[00:00:00->00:10:00] On January 27, 1995, the U.S. Polar Expedition to Antarctica experienced a series of mysterious and puzzling events.Early that morning, a thick gray mist surrounded the science station where the expedition was located, and the sky, which should have been the beginning of the day, was shrouded in gloom.The expedition members were puzzled by the unusual phenomena of noticing a piece of freshly cooked bread in the snow and men riding on a frozen lake.As time passes, the expedition discovers a creature that appears to be dead but undecayed, a phenomenon that confuses them even more.After some discussion, the expedition decided to use a weather probe to measure this strange phenomenon.However, the data returned by the probe was even more shocking - it showed the same day and month as the current one, but the year was completely different, pointing to 1965.The discovery triggered a great deal of panic among the expedition.They started double-checking all the equipment, but everything seemed to be working fine.After many attempts, they realized that every time they launched the probe, the chronometer always showed a bygone era.Just as the expedition is feeling desperate, the seemingly dead creature suddenly disappears and the device returns to normal.This event made the expedition realize that they may have encountered some sort of temporal anomaly.Meanwhile, the video is interspersed with stories of strange events at the U.S. Polar Station in the waters of the North Atlantic in August 1994, and the mysterious appearance of a baby after the sinking of the Titanic in 1912.These events all seem to be related to time anomalies, further adding to the confusion and fear of the expedition.Scientists have begun to explore possible scientific explanations behind these phenomena, including theories such as time gates and parallel worlds.The video mentions historical examples such as the 19th-century American Civil War scene witnessed in flight by Soviet fighter pilot Viktor Orlov in 1976, and the medieval European scene seen by NATO pilot Roitman over Florida in 1993.These examples suggest that time gates or spatio-temporal anomalies may not be isolated events, but rather global phenomena that span multiple centuries and regions.Ultimately, the video explores hypotheses about the existence of parallel worlds and the possibility of time gates as a gateway to different worlds.Scientists believe that in certain specific anomalous zones, the boundaries thin, allowing humans to transition from the real world to other spaces and dimensions.These studies have not only challenged our traditional understanding of time and space, but have also opened up infinite visions of the unknown.The video concludes with the research of Russian scientist Nikolai Kozyrev, who proposes that there is another universe parallel to ours in the universe, and that it is possible to time travel through tunnels of black and white holes.Although these theories are full of science fiction, they provide a new perspective for exploring time anomalies and inspire people to explore the mysteries of the universe.[00:10:00->00:20:00] The video shows a boy in a purple shirt and glasses standing in a room, talking to the camera.He describes a mysterious scientific station located in the Soviet Union that specializes in the peculiar phenomenon of locust flight.The boy mentioned that the flight of locusts had once been a feature of the country, and that the State had invested a great deal of effort in that regard, not only by studying bacteriology, but also by creating bacteriological weapons, climate-constructed weapons and biological weapons, such as those capable of destroying everything like a swarm of locusts.These weapons are so powerful that they are capable of destroying hundreds of hectares of fortifications.The video then switches to a close-up shot of a clock whose hands seem to be running normally, but the boy continues his narration, mentioning that the fortifications are actually meant to keep an eye on an island that is believed to be a portal to another dimension.As the music plays, the scene shifts to a flower swaying in the wind, followed by a beautiful view of mountains and clouds, creating a mysterious and calming atmosphere.Local residents believe that the island has a portal to another time and place, and mysterious creatures have appeared many times.Next, the video shows a group of people walking through a dark forest, seemingly lost and looking for a way out.The density and blurriness of the forest adds to the mystery of the scene.The video then shows a man on a horse trailer, wearing a hat and seemingly enjoying the ride.This image suggests a time lapse, as the man's attire seems out of place in the background setting.The video continues, showing an incident in 1984 where a police officer detained a man who was trying to leave a certain place.The scene of men dressed in red silk robes and talking to people in Japanese or Chinese seems unusual and suggests a time warp.The video also mentions that after a long search, the police found a suitable interpreter, and that the interpreter was surprised when the interrogation began because the detainee spoke a rare dialect of Japanese.The video goes further in depth, presenting a stranger in traditional Japanese clothing who reveals during interrogation that he is a Japanese born in 1718 and has royal blood.He tells the story of how he ended up on the shore of an island after a stormy boat ride in the middle of a storm.This series of events was considered by Soviet scientists to be a case of a temporal anomaly, similar to those encountered by previous expeditions in Antarctica.The video concludes with a return to the research of the Soviet scientific station, where scientists are convinced that these cases and many others like them prove that there are many places on Earth where strange things happen, places known as "Devil's Traps", portals to space-time anomalies.The video uses the Khoroshevsky District of Moscow as an example of a region that, as one of the most geologically hazardous areas, may also be a hotspot for spatio-temporal anomalies.The video ends with the image of a thinking man, suggesting that mankind's exploration of the unknown will never stop.[00:20:00->00:30:00] The scene of the video unfolds in a sea of mystery and unknown, with a soundtrack that creates a tense and curious atmosphere.The image begins by showing a beautiful night sky. The light of the matches, like the stars in the universe, illuminates the dark sky, bringing the audience a visual experience that transcends reality.The video then switches to a smoke-filled room where a woman dressed in black is dancing in the center, her movements light and graceful, contrasting with the smoke around her, as if telling a story of time and oblivion.As the music picks up the pace, on-screen credits reveal the deeper meaning behind the scene: the scientist was forced to destroy his device and all his drawings after making a potentially world-changing discovery.This scene not only adds a layer of tragedy to the video, but also hints at the risks and challenges involved in scientific exploration.Next, the video shifts to a stormy sky, the dark clouds seem to foretell ominous, but the light of the lightning bolt illuminates the whole world in this moment, bringing a symbol of hope and light.The textual narration further emphasizes the mystical nature of the gates of time, noting that these portals to other dimensions open only in the extremes of the natural elements.This passage not only paints a picture for the audience of the intertwining of natural forces and supernatural phenomena, but also triggers infinite fantasies about the unknown forces of nature.The video then shows people strolling through the stormy streets, who don't seem to be afraid of the cold and chaos, but instead find joy in it.This scene contrasts with the stormy skies of the previous text, showing the resilience and optimism of humans in the face of the forces of nature.The video goes on to delve into the case of spatio-temporal anomalies, gradually building a grand narrative about time gates and spatio-temporal anomalies through the presentation of a series of historical events, such as anomalies recorded in the 12th century and the discovery of the Maltese underworld in the 1940s.These stories not only enrich the content of the video, but also further deepen the viewer's desire to explore time travel and the unknown.At the end of the video, returning to the research at the Soviet scientific station, scientists are convinced that these spatio-temporal anomalies are not isolated events, but are characteristic of specific locations on Earth.By showcasing the beautiful scenery and mysterious atmosphere of these locations, the video conveys the human curiosity and spirit of exploration of the unknown, while also hinting at the risks and unknowns that these explorations may entail.The video ends with the image of a thinker, leaving the viewer with unlimited space for reflection and inspiring infinite reverie on the mysteries of the universe.[00:30:00->00:40:00] In the current segment of the video, the screen shows a scene of exploration filled with mystery and the unknown.A man in a white shirt, flashlight in hand, is traveling through a narrow, dark tunnel, his journey of discovery filled with tension and curiosity.The darkness of the tunnel's interior contrasts with the brightness of the outside world, and every step is taken with extreme caution.He was followed by his girlfriend, who was holding a candle in one hand and a long scarf in the other, which became her lifeline at the crucial moment, acting as a rope to help her overcome the tunnel's perils.As they go deeper, the scene suddenly switches to a huge underground hall, where Louise (presumably one of the heroines) finds herself standing on a small step downhill, surrounded by deep darkness.She raised the candle and tried to illuminate her surroundings, only to realize that the depths of the hall seemed to hide some unknown danger.Just then, the sight of several hair-covered creatures appearing in her line of sight, trying to extinguish her candle with something soft and damp, sent a wave of horror through her.Louise hurriedly searched for a way back and eventually miraculously found a path back to the surface.The twist in this scene not only shows her resourcefulness and courage, but also hints at the complexity and danger of the underground world.The video is interspersed with footage of other explorers, including a man on a bicycle traveling through a tunnel in the dark and a terrifying scene of a woman being attacked by a monster in a darkened room, clips that further heighten the tension of the video.The video goes on to delve into the meaning behind these explorations, and through the narration of a boy in glasses and a purple shirt, the viewer learns that these underground structures and mysterious creatures may be connected to the acoustic knowledge of an ancient civilization.Experts have found that these underground shrines utilize special acoustic effects that can alter one's state of consciousness and even activate certain parts of the brain to promote meditation and hypnosis.The video concludes with a series of shots of beautiful natural landscapes and historical sites, returning to marvel at the wisdom of ancient civilizations.These underground structures are not only marvels of technology, but also symbols of mankind's exploration of the unknown and pursuit of truth.The video ends with the image of a thinking man, leaving the viewer with endless room for imagination and inspiring a passion for exploring the mysteries of the universe and time.[00:40:00->00:50:00] In the video, the camera switches to a group of explorers who are struggling to climb the rock, seemingly searching for a mysterious location and enjoying the breathtaking view from the top of the rock.The soundtrack creates an atmosphere of historical chronicles with subtitles that read, "Historical chronicles tell some absolutely amazing things." The camera then pans to the interior of a cave, where camera shake reveals details of the caves, which appear to be naturally occurring, possibly caused by erosion or geological processes.The caption further explains that the formation of these caves dates back to 2300 BC, marking the end of the era of the Maltese temple builders.The explorers continue deeper into the cave, the light in their hands casting mysterious shadows in the darkness as if they were exploring a lost civilization.The walls of the caves are inscribed with ancient symbols, suggesting that this was once an important site for an ancient civilization.The subtitle mentions that the Maltese temple builders created a brilliant civilization that included many cultural monuments that suddenly disappeared at some unknown point.The camera pans to a woman in a black jacket and pants as she navigates a narrow, dark tunnel, and a voice in the background explains that many mysterious subterranean objects have suddenly and inexplicably disappeared, which has become a major mystery explored by modern researchers.The image shows a group of explorers standing in front of a huge stone wall, seemingly exploring the ruins of an ancient city, as they scrutinize the historical traces at the site in an attempt to unlock the secrets of an ancient civilization.The video goes on to show a range of theories and hypotheses about ancient civilizations, including natural disasters leading to the demise of civilizations and invasions by foreign enemies.However, the subtitle emphasizes that no single theory can fully explain the disappearance of the Maltese temple builders.Some archaeologists believe that these ancient inhabitants may have secretly evacuated the island through tunnels in the ground, and that these tunnels may even lead to other times or dimensions.The video shows a man in a helmet holding a flash light as he explores a dark tunnel, his every step seemingly cautious.There seems to be a mysterious point of light at the end of the tunnel, hinting at unknown secrets.The video also shows footage of other explorers, including a man riding a bicycle through a tunnel in the dark and a woman being attacked by a monster in a dark room, scenes that further heighten the tension of the video.The video concludes with a series of shots of beautiful natural landscapes and historical sites, returning to marvel at the wisdom of ancient civilizations.A boy in a purple shirt tells the room that these underground structures are not only marvels of technology, but also symbols of mankind's quest for the unknown and the pursuit of truth.The video ends with the image of a thinking man, leaving the viewer with endless room for imagination and inspiring a passion for exploring the mysteries of the universe and time.[00:50:00->01:00:00] In the video, the scene switches to an ancient Chinese painting showing a man in ornate clothing and a crown, who appears to be a ruler or king.The narrator explains that this great enlightened man ruled the Celestial Kingdom between 259 and 210 B.C., the reign of Qin Shi Huang.The video further explains that the country had reached a state of splendor before the death of Qin Shi Huang, and that the emperor had ordered the construction of a huge burial chamber on Mount Li (shown in the video as "Lai Sha Shan") during his lifetime, which was only discovered on the day of the emperor's funeral.As the video progresses, the screen shows a beautiful sunset scene with the sun slowly setting on the horizon and the sky filled with brilliant clouds, hinting at the mystery and magnificence of the tomb of Qin Shi Huang.Next, the video shows a man dressed in black standing in front of a mountain, who seems to be showing something to the viewer, as the background music and images create a sense of historical weight.The video further reveals that Qin Shi Huang's tomb was not only massive, but also extremely lavishly decorated with rivers flowing through it, but these rivers were actually made of mercury, symbolizing the emperor's vision of the afterlife.The mausoleum replicates Chinese cities, forests and mountains, and even the Great Wall of China is available in miniature.Experts in the video point out that the replicas not only demonstrate Qin Shi Huang's desire for eternal rule, but also the level of technology and artistic achievement in ancient China.The video shows a scholar wearing glasses and a white jacket sitting in front of a green screen as he details the findings in the tomb, including thousands of terracotta warriors, each with their own distinctive features, apparently based on images of real soldiers.Scholars also mentioned that the terracotta warriors were very well crafted, using paints and varnishes that would ensure that the statues would remain intact for the next 5,000 years.The video emphasizes the grandeur and mystery of Qin Shi Huang's tomb through a series of shots of beautiful natural landscapes and historical sites, leaving the viewer with endless room for imagination.At the end of the video, the scene returns to modern times, showing the story of a farmer who accidentally discovered the Terracotta Warriors in March 1974 while digging a well near Mount Li.The discovery shocked the world, and archaeologists quickly intervened, gradually unveiling the mystery of Qin Shi Huang's tomb after years of excavation.The video ends with the image of a deep-thinking scholar, suggesting that mankind's exploration of ancient civilizations will never stop, and that the discovery of Qin Shi Huang's tomb is just the tip of the iceberg, and that there may be more unknown wonders waiting to be discovered in the future.[01:00:00->01:10:00] The video shows a man in a white shirt standing in front of the camera, looking directly at the camera as he expressionlessly tells a story about Shi Huangdi.As the video progresses, the screen switches to different scenes, each with subtitles that complement the content of the screen.Close-ups of men's faces are replaced by multiple images, including a smiling man holding a hat, a woman advertising a product or service, and a man walking through a door into a dimly lit room.In the video, subtitles and images together reveal the brutal rule of Emperor Shi Huangdi and his desire for power.Shi Huangdi unified China through extreme means, suppressing all those who opposed him and even executing thousands of intellectuals and nobles who were perceived as a threat.Meanwhile, in his quest for immortality, he dispatched a large number of expeditions in search of the legendary elixir of immortality, but ultimately these efforts ended in failure.Shi Huangdi's fear comes not only from the reality of his enemies, but also from his worries about the world after death.To ensure his safety in the afterlife, he ordered the construction of a vast mausoleum containing not only rivers made of mercury, but also thousands of terracotta warriors designed as his army to protect him from his enemies.A key turning point in the video is when Emperor Shi Huangdi decides to execute 4,000 of his best warriors to accompany him into the afterlife, and a senior councillor warns of the possible consequences of this decision.The councillor pointed out that if the best fighters were killed, the people might revolt, which would lead to the collapse of the empire.Eventually, Emperor Shi Huangdi accepted the counsellor's advice and decided to use terracotta figurines instead of living human beings, a decision that not only protected his soldiers but also left a stunning artistic legacy for future generations.The video goes on to show how the mausoleum was built, and the subsequent archaeological discoveries.Through radiocarbon analysis, the scientists determined that the plant pollen found on the terracotta warriors came from different regions of China, suggesting that the duty of making these terracotta figures was assigned to various provinces of the empire.The video also reveals the traps and mechanisms in the mausoleum, which are designed to protect it from grave robbers.Nonetheless, the mausoleum was ransacked after the fall of the Qin Dynasty by rebels who made use of the real weapons in the terracotta warriors.The video concludes with a discussion of modern archaeological discoveries, showing the restoration of Qin Shi Huang's tomb and an evaluation of the most controversial ruler in history.Through a series of shots of beautiful natural landscapes and historical sites, the video highlights Qin Shi Huang's tomb as a symbol of ancient China's technological and artistic achievements, as well as leaving behind many unanswered questions that inspire unlimited visions of ancient civilization.The video ends with the image of a deep-thinking scholar, leaving the viewer with endless space for reflection and reminding people of the complexity of history and the many facets of human nature.[01:10:00->01:20:00] The video shows a man in a jacket and what appears to be a rat talking to the camera, his expression is serious and he seems to be telling an important story.He referred to the allegations regarding mercury-containing pills, which had accused him of finding medications that did not contain mercury, and even questioned how he had found them.A beautiful garden appears in the video, and the setting appears calm and peaceful, while the subtitles continue the legend of the elixir of immortality, which seems to have taken place in 200 BC, three years after the establishment of the Qin Empire.The scene then switches to a bird singing in the forest, with background music and natural surroundings creating a harmonious atmosphere.The subtitles continue the story of the legend of the elixir of immortality in 200 B.C. and the fall of the Qin Empire three years later due to an onslaught of internal and external factors.The video features a beautiful sunset scene in a city where the sky is lit up with vibrant colors and the city's buildings look beautiful in the sunlight.The subtitle mentions that the Qin Empire collapsed three years later due to the impact of internal and external factors, further emphasizing the tragic nature of this turning point in history.The video then shows a tense and orderly scene as a group of people stand in front of the burning building as they try to extinguish the blaze.The subtitle explains the collapse of the Qin Empire under the attack of internal and external enemies, further revealing the complex reasons for the fall of the Qin Empire.Next, the video shows an explosion that fills the room with smoke and flames, seemingly caused by a gas leak.The subtitle mentions that the internal enemies of the Qin Empire still rest in mercury to this day, alluding to the rivers of mercury in Qin Shi Huang's tomb and its symbolism.The video then shows beautiful natural scenery, including sunsets over mountains and lakes, sunlight reflecting warmly off the water, and skies covered in shades of orange and pink.The caption mentions that some believe the mercury was meant to protect the remains of Qin Shi Huang, as many believed that the age of the legendary emperor was imminent.In the video, a man dressed in traditional Chinese clothing stands in front of a painting depicting a Chinese emperor, and the caption mentions that the legendary emperor will be resurrected and his army of terracotta warriors will come to life to reconquer the world.This scene connects ancient legends with modern archaeological discoveries, inspiring viewers to think about history and the future.The video goes on to show beautiful natural scenery, including an old bridge and beach dwellers, with captions referring to Mr. William Monroe's experience in June 1890 in a small town in northern Scotland, where he saw a mysterious creature, which sparked a discussion of mermaid lore and historical records.The video concludes with a display of various legends and historical accounts of mermaids, including legends from different countries and regions, as well as research on old ship logs by Canadian historians in the late 1970s.These stories not only enrich the video, but also deepen the viewer's interest and curiosity in the mysterious creature of the mermaid.Through a series of beautiful natural landscapes and historical scenes, combined with subtitled narration, the entire video transports viewers into a world full of mystery and historical fascination, inspiring exploration of the unknown and ancient civilizations.[01:20:00->01:30:00] In the video, the footage shows a rocky island surrounded by sea water, which from the air appears to be a pure land undisturbed by humans.Next, the video switches to footage of a man in a water suit diving underwater, sinking into the water and then seemingly resurfacing, a scene that is full of mystery and suggests some sort of supernatural or unknown force.The scene suddenly shifts to a dark scene with the sound of a train in the background, creating a horror movie atmosphere.The caption explains that English traveler Father Henry's ship suffered a tail attack, but the marina did not have any attacks related to fish tails on women's bodies.This narrative echoes the mysterious phenomena encountered by previous expeditions in Antarctica, further deepening the audience's curiosity about these supernatural events.The video then features a beautiful shot of an aquarium with creatures swimming freely in clear blue water, seemingly in contrast to the previous tense scene.However, the subtitles continue to emphasize the plot of the attack on Father Henry's ship, a contrast that gives the viewer a deeper sense of the unknown and danger in the ocean.The video goes on to show a group of people hurrying through the tunnel, seemingly looking for something.The quick and tense movements of these characters add to the urgency of the video.This is followed by a group of surfers enjoying the waves in the ocean, a scene that again contrasts with the tension of the previous text and reflects man's love and reverence for nature.As the video progresses, the beauty of the sunset gradually unfolds in front of the viewer's eyes, with the shimmering of the sea and the brilliant colors in the sky creating a serene and beautiful atmosphere.However, the credits mention a man recording the back of a mermaid in his diary, an episode that pulls the viewer's mind back to the mysterious creatures of the ocean once again.The video shows a woman dressed in white standing in front of a wall with a mysterious shadow behind her that appears to be singing.This scene creates a mysterious and slightly scary atmosphere through the contrast of light and shadow, depicting a legend about mermaids for the audience.The scene is followed by a man walking on the beach, slapping his feet against the water, while the scene appears to be lighthearted, again reflecting the video's narrative style of alternating tension and relaxation over and over again.The video concludes with a series of shots of beautiful natural landscapes and historical sites that demonstrate mankind's passion for exploring the unknown.A man in a blue shirt sits in front of the camera and details mermaid lore and the historical record, emphasizing the global nature of these mysterious creatures and the many sightings throughout history.The video ends with the image of a thinking man, leaving the viewer with endless space for imagination and inspiring a desire to explore the unknown world of the ocean depths.[01:30:00->01:40:00] The video shows a man in a helmet riding a boat on the water, enjoying the beautiful nature around him, with the sun shining on the sparkling water, adding a bit of peace and tranquility.Behind this serene scene, however, lies a disturbing reality.The video's subtitles reveal that the mysterious underwater creatures have attracted a great deal of attention from the military, and national intelligence agencies are trying to track them down.The agencies used sonar weapons to probe underwater in an attempt to capture the creatures' beams, but the results were unexpected.Next, the video switches to a young man in a blue shirt who stands in front of a black background with a serious expression as he narrates to the camera.He explained that intelligence agencies of various countries are trying to destroy these creatures through special operations underwater with sonar weapons, such as high pulse or sonic booms.However, these attempts do not appear to have been successful.The video shows underwater creatures being destroyed by a sonic boom, but then all the destroyed creatures are washed ashore as if some supernatural force is protecting them.The scene of the video switches again to show a beautiful sunset scene, with the sun casting a warm orange glow over the water and the sky covered in brilliant colors, creating a serene and beautiful atmosphere.The subtitles continue to tell that not long ago, these mysterious creatures died suddenly somewhere, an event that unraveled the mystery of this place.The video mentions a training camp that took place on the western shore of Lake Baikal in 1982, where swimming combatants from the Trans-Baikal military district were training on the lake, and when the divers descended to a depth of 50 meters, they encountered a creature that was more than three meters tall.The creatures' bodies were encased in a shimmering coat and their heads were hidden under a spherical helmet, but they were clearly no ordinary divers.The video shows divers coming face-to-face with the creatures, who initially seem to make friendly eye contact with the divers, which solves part of the mystery.In order to uncover more secrets, the drill commander orders the capture of one of the creatures.A special team of the most experienced divers, well-equipped, attempted to catch the creatures in nets.However, when the hunters cast their nets, some powerful force instantly pushes the entire group overboard, causing all the crew to suffer from Kesson's Syndrome, a serious illness that remains a mystery.The video goes on to show the salt problems these creatures have along Lake Baikal and the question of whether or not they are intelligent.The video mentions that the underwater inhabitants are intelligent, but their numbers have become so small that contact or communication with them often occurs when they mysteriously surface.The video concludes with a reference to a report released by the National Oceanic and Atmospheric Administration (NOAA) that emphasizes the importance of atmospheric research and mentions that mermaids exist and inhabit bodies of water around the world.The video ends with a display of fish-tailed beauties from cave murals that were found in the Late Paleolithic period, about 30,000 years ago.These murals not only show early human imagery of mysterious creatures, but also suggest that the existence of these creatures may have spanned a long history.The video ends with the image of a group of people exploring a cave in the darkness, using torches to light up a narrow passageway, full of curiosity and the spirit of exploration of the unknown.Through these scenes and narratives, the video inspires the viewer to fantasize about the underwater world and its mysterious creatures.

C. Because these people entered the underground labyrinth and encountered toxic gas emissions that induced hallucinations, leading them astray until they succumbed.
D. Because these people entered the underground labyrinth and had their brain consciousness disrupted by sound waves of a certain frequency, and ended up lost in the caves and died.

Answer: D

Why do people who enter the underground labyrinth end up disappearing?

Because these people entered the underground labyrinth and had their brain consciousness disrupted by sound waves of a certain frequency, and ended up lost in the caves and died.

Several teens stumble upon an underground labyrinth and are driven by curiosity to enter the caverns, where they all eventually disappear. [00:23:38->00:24:15]

A number of volunteers entered the dungeon in search of the youths, only to have them all disappear as well. [00:24:16->00:24:31]

The archaeologists, with the help of their tools, enter the third level of the underground labyrinth, where they find the remains of those lost in the caves. [00:28:12->00:28:47]

Scientists have discovered that underground labyrinths are special structures that resonate to produce sound waves of a certain frequency to disrupt the consciousness of the brains of those who break into the caves. [00:36:20->00:37:51]

Scientists continue to explain the mysterious acoustic phenomena of the underground labyrinth, where a prolonged screeching sound, as if moaning from the depths of the earth, has been heard in the caves, and it is this strange sound wave that disrupts the cerebral awareness of those who enter the caves, causing these people to get lost in the caves and eventually disappear.

The video's footage focuses on a narrow tunnel that a man in a hat is carefully exploring.The flashlight in his hand cast a weak beam of light that illuminated the uneven tunnel walls ahead.The air inside the tunnel seemed to freeze, only the sound of the man's footsteps and breathing echoed in the silence.He scrutinized every detail of the tunnel walls as if looking for some kind of clue.The narrator of the video mentions that these tunnels are the ventilation system for the tomb of the pharaoh's wife, but surprisingly, the vents do not lead to the surface.They didn't even extend to the interior of the catacombs, but came to an abrupt end halfway through.The man continued on and a door sealed by a metal plate appeared at the end of the tunnel.The two metal stud handles on the door stood out in the dim light.The man tried to open the door with the tool in his hand, but apparently to no avail.The next scene switches to a group of researchers busy in a lab.They wore blue lab coats and focused on operating various equipment.In the background, a drone hovers in the air as if monitoring the process.The narrator explains that it wasn't until 1990 that a robot assembled specifically for this mission finally managed to crawl through the 63-meter tunnel and reach the sealed door.However, the robot also failed when it tried to open the door in 2002.The scene switches again to show the robot exploring the tunnel.The robot crawls slowly as the camera captures every detail of the tunnel's interior.When the robot reaches 63 meters, it notices an obstacle ahead - a door sealed by a metal plate.The robot tries to drill a hole and insert a camera, but finds another door 20 centimeters behind it, almost identical to the previous one.The video goes on to show the complexity and mystery of these tunnels.Researchers have tried to unlock the secrets behind these tunnels and doors, but have never been able to break through.It wasn't until 2002 that another robot came to the door again, and this time it managed to drill a hole in the door and point the camera at the opening.However, the footage coming back from the camera showed that there was still a door behind it, which further deepened the researchers' confusion.At the end of the video, the footage shows the researchers discussing in the lab.They seem to be exploring the real purpose of these tunnels and doors and why they are designed as they are.The narrator mentions that the design of the tunnels and doors may hide some unknown secret, and that the key to unlocking these secrets has yet to be found.Researchers continue to conduct a variety of experiments and analyses, but have so far been unable to fully unravel the mysteries of these ancient structures.[00:20:00->00:30:00] The video gradually switches from an old map to a modern aerial view.A black-and-white image of a mountainous region with a meandering river running through it appeared first on the screen in what appeared to be an ancient image.The narrator mentions that it wasn't until the 1970s that this mysterious land became known to the world.The scene then switches to a shot of a drone flying over a city.The drone is equipped with a camera that captures high-resolution images of the city, including buildings, roads and infrastructure.The narrator explains that at the turn of the century, it was imperative to build on the original site to cope with the city's growth.The image then shows a busy traffic scene in the city, with traffic flowing on the roads on what appears to be a busy day.The narrator mentions that a pyramidal freeway overpass needs to be built in place to improve traffic conditions.The camera then focuses on a busy route with yellow lines marking the planned route.The video goes on to show a map of the highway with a yellow circle marking accident-prone locations.The narrator emphasizes the need for a pyramidal freeway overpass at that location to improve traffic safety.The camera then switches to the Pyramid of San Andres, a pyramid that appears to be built of stone and located in the desert, with tourists seen in the background taking pictures around the pyramid.The narrator mentions that St. Andrew's is a proof that Europe had a highly developed civilization before the Romans, before the rise of the Roman Empire and Christianity.However, scientists do not believe that this evidence is sufficient to protect the monument.The scene switches to a group of tourists exploring around the pyramids and learning about their history.The video goes on to show the importance of preserving monuments.The narrator mentions that the preservation of the oldest European cultural monuments is now of great significance.The camera then switches to a group of people in ancient costumes walking through the streets, seemingly recreating some historical scene.Then a woman in ancient Egyptian decorations stood in the room, wearing a crown and looking like a queen.The narrative of the video continues to go deeper, mentioning the French culture's quest for beauty, which the French must travel to Egypt or Mexico to experience.The camera switches to a group of people dressed in white meeting in a room, one of whom appears to be a leader.The narrator mentions that the French had to travel to these distant places to experience the beauty of the ancient civilization.The final part of the video shows pyramids and similar structures from around the world.The camera switches to a man on a skateboard traveling on a dry road, seemingly enjoying the ride.The screen then shows a satellite view of the Earth's surface, focusing on the Arctic region.The narrator mentions that some content on Google Maps periodically disappears, which has sparked a lot of speculation.The video ends with an aerial view of an airplane flying over a field, which appears to be flying high in the sky.The narrator mentions that the disappearing contents may be secrets that for some reason should not be known to the public.The final line of the video is thought-provoking: is everything so simple and straightforward in our world? [00:30:00->00:40:00]### Narrative description of current video content

The camera of the video focuses on a complex diagram depicting a pyramid, with the individual parts labeled in detail.The pyramid is made of different materials and each part has a unique function.The narrator explains that the pyramid is not only an ancient structure, but also an energy conversion device.Pyramids convert energy into a usable form by means of resonant oscillating circuits, a technique described in modern language as an energy conversion device.The pyramid was surrounded by stone rings that were built to receive the vibrations of the pyramid through inductive coupling, making the temple a resonance center for the vibrations of the pyramid.The scene switches to a 3D animation of the pyramid, which emerges in the shape of a triangle and seems to float in the air.The narrator goes on to explain that the pyramid not only serves as a conversion station for energy, but also transports energy to the next device through underground tunnels.These underground tunnels are not only a path to the temple, they are a waveguide that transfers energy efficiently.The video shows a virtual tour of the Great Pyramid of Giza, starting from a bird's-eye view and gradually switching to a 360-degree panoramic view of the pyramid's grandeur and complexity.Next, the video shows an aerial view of the Pyramids of Giza, which are located in the middle of the vast desert and appear to be particularly grand.The narrator mentions that for many people, these pyramids are just ancient temples, but the science and technology behind them goes far beyond the imagination.Researchers are busy in their labs trying to unlock the secrets of these pyramids and tunnels.They operated a variety of equipment in an attempt to understand the true purpose of the pyramid.The video goes on to show the inner workings of the Giza pyramid, where the researchers demonstrate the intricate design of the pyramid's interior through 3D modeling and virtual reality simulations.The narrator mentions that the internal structure of the pyramid includes not only traditional burial chambers, but also a complex series of tunnels and waveguide systems, the design and construction techniques of which remain a mystery.The final part of the video shows pyramids and similar structures from around the world, from the Pyramids of Giza in Egypt to the ancient city of Teotihuacan in Mexico.The narrator mentions that these ancient structures not only demonstrate human ingenuity, but also suggest some sort of global system.However, why the system no longer works, and the real purpose behind it, remains an unsolved mystery.The video ends with an aerial view of an airplane flying over a field, and the narrator poses a thought-provoking question: is everything really so simple and straightforward in our world?

The video gradually switches from an ancient map to a modern satellite view, demonstrating the evolution of human civilization and the constant progress of exploration.These ancient pyramids and mysterious structures are not only a reminder of our past, but also a revelation of the future.[00:40:00->00:50:00] The video footage focuses on a drone flying over a river, equipped with a camera that captures breathtaking images of the river and its surrounding landscape.The river meanders through lush valleys and the sunlight glints off the water, creating a serene and beautiful image.The narrator mentions that civilization built such an extraordinary city, but we have begun to answer questions about the city and what we have become, which are unanswered questions.The camera then switches to a city of tall buildings with airplanes flying through the sky.The city scene is bustling and busy, with traffic on the roads and skyscrapers standing under a blue sky.The narrator goes on to say that the city and what has become of us are unanswered questions.Until answers are found, our planet appears to be undergoing a protracted experiment in civilization that has been going on for tens or even hundreds of thousands of years.The scene then shifts to an aerial view of a forest, with the airplane flying high in the sky, the green of the forest covering the ground, and sunlight shining through the canopy of trees, creating dappled light.Again, the narrator emphasizes that this experiment in civilization has been going on for tens, if not hundreds of thousands of years.Next, the camera switches to the interior of a cave, in the center of which sits a statue of Buddha made of white stone.The interior of the cave was dimly lit, with only a few beams of sunlight spilling through the opening onto the statue, giving it a solemn appearance.The narrator mentions that traces of these civilizations exist not only in cities and natural landscapes, but are also hidden in ancient caves and statues.The scene then switches to a library full of books, which are neatly arranged on the shelves, and the camera pivots to capture the details of each book one by one.As an aside, the narrator mentions that most people remember the Pyramid of Cheops, one of the Seven Wonders of the World, from their high school history classes.The camera then focuses on the Great Pyramid of Giza, the world's most famous pyramid, which attracts countless visitors with its impressive size and construction techniques.The video goes on to show several other structures from the Seven Wonders of the World, including the Hanging Gardens of Semiramis, the statue of Zeus in Olympia and the Temple of Artemis in Ephesus.These ancient structures not only demonstrate human ingenuity, but also suggest some kind of global system.However, why the system no longer works, and the real purpose behind it, remains an unsolved mystery.The final part of the video shows pyramids and similar structures from around the world, from the Pyramids of Giza in Egypt to the ancient city of Teotihuacan in Mexico.The narrator mentions that these ancient structures not only demonstrate human ingenuity, but also suggest some sort of global system.However, why the system no longer works, and the real purpose behind it, remains an unsolved mystery.The video ends with an aerial view of an airplane flying over a field, and the narrator poses a thought-provoking question: Is everything really so simple and straightforward in our world? The video gradually switches from an ancient map to a modern satellite view, demonstrating the evolution of human civilization and the constant progress of exploration.These ancient pyramids and mysterious structures are not only a reminder of our past, but also a revelation of the future.[00:50:00->01:00:00]### Narrative description of current video content

The video's footage focuses on Lake Vostok in Antarctica, a lake hidden under a thick sheet of ice and virtually isolated from the rest of the world.The camera switches to the ice on the surface of the lake, which takes on a distinctive transparency as sunlight shines through it into the depths of the lake.The narrator mentions that the temperature of the lake is kept at 10 degrees Celsius due to the geothermal heat underneath, and the ice is several meters thick.These conditions keep the lake from freezing and provide a unique environment for the organisms in the lake to survive.Next, the video shows icicles in the lake that seem to act as natural insulators, protecting the biological organisms in the lake.Scientists speculate that these icicles not only preserve organisms, but may also provide a stable environment for organisms in the lake to survive.The camera switches to creatures in the lake, including slow swimming seals and various fish.The narrator mentions that these creatures have evolved over millions of years and have adapted to this extreme environment.The video then shows the location of Lake Vostok and the surrounding ice.The camera looks down from the air and shows huge glaciers and icebergs that seem to be slowly melting and splitting apart.The narrator mentions that Lake Vostok is located under the Antarctic ice sheet, which is several kilometers thick.Scientists have studied the organisms in the lake intensively and have discovered some unique gene sequences that do not match any known organisms.The video goes on to show researchers working in the lab.They wore blue lab coats and operated a variety of advanced equipment in an attempt to unlock the secrets of these genetic sequences.The narrator mentions that the complexity and uniqueness of these gene sequences exceeded scientists' expectations, and that some of these genes even match eukaryotic traits.The camera switches to microscopic bacteria and viruses, showing the fine structure of these microorganisms.At the end of the video, the screen switches to a global map marking the location of Lake Vostok.The narrator mentions that the lake is not only a scientific marvel, but may also hide key human clues to ancient civilizations and biological evolution.The video ends with an aerial view of an airplane flying over an icy lake and snow-covered mountains, and the narrator poses a thought-provoking question: is everything really so simple and straightforward in our world?

The video gradually switches from an ancient map to a modern satellite view, showing the evolution of human civilization and the constant progress of exploration.These ancient lakes and mysterious structures are not only a reminder of our past, but a revelation of our future.The final image of the video is framed on a beautiful Antarctica glacier, with the sunlight shimmering on the ice, creating a serene and mysterious atmosphere.[01:00:00->01:10:00]### Narrative description of current video content

The video's frame focuses on a building in front of which a man in a white shirt and black pants stands, holding a camera.He appeared to be engaged in some kind of filming or investigation, and his surroundings seemed quiet and serious.The camera then switches to a large stone structure which appears to be an old monument.The camera rotates slowly around the structure, revealing its stunning paintings and details.The delicacy of these details makes one marvel at the skill of the ancient artisans.The narrator of the video mentions that the stone structure weighs about 500 to 600 tons, the size of which is usually just billets, and will presumably be used for construction or other large projects.The camera then switches to an aerial view of a rocky area with a large tree in the center, surrounded by a dense forest.The narrator explains that the amount of rock removed was about 400 cubic meters, which equates to about 1,000 tons of weight, further emphasizing the massive size of this stone structure.Next, the video shows a man with a light bulb in his hand walking through a dark and narrow cave.His flashlight cast a faint beam of light in the darkness, illuminating the tunnel wall ahead of him.He scrutinized every detail as if looking for some kind of clue.The narrator mentions that the construction and design of these tunnels is full of mystery, and scientists are still researching the true purpose of these tunnels.The video goes on to show a man on a skateboard, wearing a helmet and seemingly enjoying the excitement of the ride.He walks through a beautiful park with trees and green vegetation in the background, the sunlight pours through the leaves on the ground, creating dappled light and shadows.The narrator mentions that these ancient structures not only demonstrate human ingenuity, but also hint at some sort of global system, but why this system no longer functions, and the true purpose behind it, remains an unsolved mystery.Next, the video shows an aerial view of the city taken from a drone.Drones fly over cities, capturing high-resolution images of buildings, streets and people.The city looks busy and bustling with traffic on the roads and skyscrapers standing under a blue sky.The narrator mentions that the growth and changes in cities are part of human civilization, but the history and secrets behind these changes are still worth exploring.The final part of the video shows pyramids and similar structures from around the world, from the Pyramids of Giza in Egypt to the ancient city of Teotihuacan in Mexico.These ancient structures not only demonstrate human ingenuity, but also suggest some kind of global system.However, why the system no longer works, and the real purpose behind it, remains an unsolved mystery.The video ends with an aerial view of an airplane flying over a field, and the narrator poses a thought-provoking question: is everything really so simple and straightforward in our world?

Question: Mystery Base Discovered Hiding Military Secrets What happens when secrets are released to the world?

Choices:
A. The release of secrets from mysterious bases typically results in widespread public panic, as the information is often exaggerated or misinterpreted by media outlets.
B. Military secrets revealed from mysterious bases often lead to immediate international conflicts, as nations scramble to protect their interests and respond to the exposed information.
C. Mysterious bases are not the main places where military secrets are hidden, but rather camouflage used to distract the public's attention The secrets that appear on the surface may be used to conceal deeper hiding places, and the real secrets may exist in other, more secretive locations.
D. When secrets from mysterious bases are disclosed, they are usually outdated or decoy information, designed to mislead adversaries while safeguarding current operational strategies.

Answer: C

Mysterious bases are not the main places where military secrets are hidden, but rather camouflage used to distract the public's attention The secrets that appear on the surface may be used to conceal deeper hiding places, and the real secrets may exist in other, more secretive locations.

The video references the mysterious base widely believed by the public to be a place to test new weapons systems, and its secrecy has sparked much speculation. [00:00:02->00:02:21]

The video further discusses that this may have been a diversionary move, and that the secrets revealed on the surface may have been used to conceal deeper hidden locations. [00:03:23->00:06:20]

The complex of military installations in the video purposely protects the secrecy of these locations, and their external exposure may imply a conscious intent to hide other locations. [00:06:20->00:08:21]

Question: Why was the facility complex in the Nevada desert not officially recognized until later?

Choices:
A. The complex was initially classified as a temporary research site, and its permanent status was only confirmed after extensive evaluation.
B. The facility's remote location and harsh environmental conditions delayed the completion of necessary infrastructure for official recognition.
C. Initial funding constraints and bureaucratic delays in government approvals postponed its formal acknowledgment.
D. This is because of the early need to maintain strict confidentiality of its use and activities to avoid disclosure of sensitive national information.

Answer: D

This is because of the early need to maintain strict confidentiality of its use and activities to avoid disclosure of sensitive national information.

The video points out that the facility within the Nevada desert was long kept secret from the public, and was not officially recognized until later in the year. [00:00:20->00:02:21]

The video's brief mention around its use suggests a sensitive nature, and there are references to possible testing of the new weapon system. [00:02:21->00:03:36]

Combined with a general awareness of the need for military secrecy, it is hypothesized that the early avoidance of exposure was to protect nationally classified technology development and testing. [00:03:36->00:06:21]

Choices:
A. Modern engineers lack the physical strength and endurance required to replicate the labor-intensive methods of ancient Havasuite masons.
B. Contemporary construction regulations and safety standards prevent the use of traditional Havasuite building practices.
C. The precise geological conditions and materials available in ancient times have been permanently altered by environmental changes.
D. This is because they have mastered building techniques unknown to modern science and have unique tools and cultural backgrounds that meet the specific needs of their society.

Answer: D

This is because they have mastered building techniques unknown to modern science and have unique tools and cultural backgrounds that meet the specific needs of their society.

The video shows the incredible precision of the polygonal masonry work at Machu Picchu. [00:57:07->01:07:58]

The narrator mentions that modern craftsmen try to imitate but ultimately do not fully succeed, implying that there is a technological and material discontinuity. [01:07:58->01:10:58]

Ancient craftsmen may have developed completely different construction methods than modern ones based on specific societal needs that cannot be deduced in reverse purely from surviving remains. [01:12:58->01:15:58]

Question: How many messages might the unique genetic sequence of a mysterious Antarctic lake suggest?

Choices:
A. It implies 3 kinds of information
B. It implies 4 kinds of information
C. It implies 2 kinds of information
D. It implies 5 kinds of information

Answer: A

The first in the video hints at the ecosystem of Lake Vostok, which is isolated from the outside world by being covered in ice for long periods of time, which gives the lake's organisms a unique evolutionary path. [00:48:31->00:49:58]

The second in the video hints at the fact that scientists have discovered a gene sequence that does not match any known organism and is more specific than expected. [00:50:57->00:51:58]

The third in the video hints at the profound influence of ecology on the evolution of life, while informing the exploration of extraterrestrial life and biodiversity research. [00:52:03->00:53:58]

Question: Assuming the claim that the mysterious ancient candle-like igniter is over half a million years old is confirmed, what would be the impact on the perception of human history?

Choices:
A. The discovery would imply that early humans relied solely on natural phenomena for fire, diminishing the role of technological innovation in ancient societies and their survival strategies.
B. This would suggest that the development of fire technology was a global phenomenon occurring simultaneously across multiple ancient civilizations, rather than a localized innovation.
C. It would confirm existing theories about the gradual evolution of human technology, reinforcing the linear progression model of human civilization without introducing significant changes to the historical timeline.
D. This will dramatically rewrite the human perception of our own technological development, suggesting that a highly developed civilization or human ancestors with advanced technology may have existed in a far more ancient period, breaking the linear pattern of human civilization development in the traditional perception.

Answer: D

This will dramatically rewrite the human perception of our own technological development, suggesting that a highly developed civilization or human ancestors with advanced technology may have existed in a far more ancient period, breaking the linear pattern of human civilization development in the traditional perception.

The video mentions the controversial claim that the ancient candle-like igniter is over half a million years old. [01:13:03->01:3258]

Assuming that the claim is confirmed, it suggests that technology and civilization beyond imagination existed in the distant past.

Humanity will be in a relatively primitive stage during this period and will break the traditionally perceived linear pattern of human civilization development.
