Xiao Fei continued to talk about the submarine pyramid just now, and said in a free voice: "By the way, there is also an underwater pyramid, scientists have found this submarine pyramid with a height of 60 meters, a width of 8,000 meters, and an undersea pyramid located 40 meters below the sea surface, which is suspected to be the remains of Atlantis, it is 60 meters high, about 1,500 kilometers of seabed, and the ridge line on all sides is just facing due east, due west, Due south and due north, similar to the Great Pyramid of Giza in Egypt. The discoverers believe that this is definitely not a natural occurrence.

Scientists suspect that it is related to the legendary Atlantean civilization. Legend has it that there was once a highly civilized country on Earth, but for some unknown reason it suddenly sank into the deep sea, which is still a mystery until now. The Azov Islands have long been considered to be the junction between the three continents of North America, Eurasia and Africa, and now the discovery of an underwater pyramid near the Azov Islands has made archaeologists even more curious about whether this pyramid is a relic of the Atlantean Empire. Legend has it that Atlantis regarded himself as a child of the god of the sea, and had a strong worship of the sea, and it coexisted on the earth at that time with the Lemurian civilization, which was located on an ancient continent northeast of present-day Australia. The two civilizations sank in the flood of extinction 10,000 years ago. Some researchers believe that Atlantis is located near Cádiz in Spain. The archaeological discovery of the marshland of Donana National Park in the north of Cadiz, Spain, by Froend, a professor at the University of Hartford, believes that this is the Atlantis destroyed by the tsunami. The waters of Spain and Portugal may be the real remains of Atlantis, after all, the seabed has never changed less than continental drift, and it is very mysterious. On the contrary, Charles Hapgood, a professor at Harvard University, proposed an understanding of the displacement of the earth's crust, which was even recognized by Einstein, but has not been recognized by the mainstream scientific community, and he believes that Atlantis is the current Antarctic Circle.

In 350 B.C., the ancient Greek philosopher Plato's "Dialogues" was widely circulated in ancient Greece. In the dialogues, Plato depicts Atlantis for the first time in the form of dialogues, translating the Atlantic Island, the Great Western Kingdom, and the Great Western Continent, the name of an ancient continent, country or city-state with a high degree of civilization in the legend, and in the dialogues, Plato depicts Atlantis for the first time in the form of a dialogue, the nearby island of the Atlantic, a legendary ancient continent, country or city-state with a high degree of civilization development, which is said to have been destroyed by the prehistoric flood in 10,000 BC. Modern science has found that before the Great Flood, there may have been a continent on Earth that had a highly developed civilization, and that in a global catastrophe, the continent sank in the Atlantic Ocean. The catastrophe was triggered by a massive earthquake and the tsunami that followed. The volcanic ash left the entire Mediterranean region in darkness for weeks, and plants as far away as Britain were affected. The earthquake was 4,000 times more powerful than the atomic bomb of Hiroshima. Nearly a century ago, archaeologists have found remains of prehistoric civilizations at the bottom of the Atlantic Ocean that seem to confirm this hypothesis. In folk sayings, people call this land Daxizhou, and the country that gave birth to prehistoric civilization is called Daxiguo. In fact, the scientific community has long named this mysteriously disappeared continent, that is, it follows the name proposed by Plato: Atlantis.

Brother Ichihue happened to walk past us and asked curiously, "What is Atlantis? ”

Xiao Fei's eyebrows fluttered and he said: "The Atlantean Empire is the name of an ancient continent, country or city-state with a high degree of civilization development in legends. The earliest description appears in the ancient Greek philosopher Plato's Dialogues, which is said to have been destroyed by the Prehistoric Flood around 10,000 BC. Legend has it that it was Poseidon, the god of the sea, who created the kingdom of Atlantis. On a small island, Poseidon married a girl whose parents had died and had five twins, so Poseidon divided the island into ten districts, each of which was ruled by ten sons, with the eldest son as the supreme ruler. Because this eldest son was called Atlas, the country was called the kingdom of "Atlantis". In the acropolis in the center of Atlantis, there is a temple dedicated to Poseidon and his wife, as well as a temple dedicated to Poseidon, which is decorated with gold, silver, brass and ivory. The shores of Atlantis are home to shipyards, docks filled with three-stage oars, and docks filled with merchant ships and merchants from all over the world. The Kingdom of Atlantis was very rich and powerful, and in addition to the abundant products of the islands themselves, tributes from Mediterranean countries such as Egypt and Syria were also continuous. The ten kings each held absolute power in their own territory, each with a different national organization, and in order to maintain communication with each other, every five to six years, they would meet in the Temple of Poseidon to discuss their relationship with each other and their ruling power, and when the agreement was established, they would cut off the throats of the bulls kept in the Temple of Poseidon, and write the words of the resolution on the pillars of the Temple of Poseidon with their blood, so as to increase the sanctity of the authority of the resolution. The ten kings were all wise, and their respective countries were rich and powerful. Unfortunately, it was not long before corruption began to emerge in these countries. Zeus, the head of the gods, punished the people for their depravity, causing earthquakes and floods, and the kingdom of Atlantis sank to the bottom of the sea in one day and one night. It also translates Atlantis, also known as the Great Western Continent and the Great Western Kingdom, and there is a similar narrative in the ancient Mexican manuscripts preserved in the Vatican City State (i.e., the Codex of the Vatican City State) and in the works of the Mexican Indian civilization that have survived to this day—there have been four generations of human beings on the earth. The first generation of humans was a generation of giants, not inhabitants of this place, but from the heavens. They are destroyed by hunger. The second generation of humanity was destroyed by a great fire. The third generation of humans was the ape-man, who were destroyed by cannibalism. Later, a fourth generation of human beings appeared, that is, in the stage of the sun and water, and the human civilization in this stage was destroyed by the great flood of huge waves. ”

Brother Yixiu listened to it and praised: "I didn't expect that there was such a splendid civilization in ancient times, human beings are really amazing, and I don't know if it's true or not." ”

I couldn't help but say: "It's really a magical underwater pyramid, but it's a pity that we don't have a pyramid because of China's vast land and outstanding people." ”

Xiao Fei continued to gush: "Why don't there be pyramids, in fact, we also have underwater pyramids in China, maybe it is also related to Atlantis." ”

I said curiously: "Really, why don't I know? Where is the underwater pyramid in my country?" Xiao Fei said in a sprinkled voice: "Don't you know this, it's too lonely and unheard, just in Fuxian Lake in Yunnan, Fuxian Lake, with a surface area of 216.6 square kilometers, is the second largest deep-water lake known in China except for Tianchi in Changbai Mountain in Northeast China. It has an average depth of 95.2 meters and a maximum depth of 158.9 meters. This is an amazing discovery made by diving enthusiasts known locally as water ghosts during their diving expeditions in Fuxian Lake, and the underwater pyramid of Fuxian Lake comes into view. The identity of the underwater ruins is mysterious, and there are many mysteries to be solved. What does this ancient city look like? When did it begin to be built? Is it the ancient city of Yuyuan recorded in the history books, or is it the capital of the ancient Dian Kingdom? Are they the same city? What caused it to sink to the bottom of the lake about 1,800 years ago? What was the way the people who once lived on this land lived and worked? At present, the area of the underwater ancient city has reached 2.4 square kilometers, and archaeologists have found a large number of ancient bronzes in the area around Fuxian Lake, with a total of 12 main buildings, which are scattered and scattered. So far, five buildings have been preliminarily detected, and these buildings have been artificially piled up with stones, and there are exquisite patterns and patterns carved on the stones. During the multi-day exploration, the experts were most excited by the strange carved symbols and patterns found on the moss-covered building stones. So far, there are five main important findings.

One is a five-hole slate. On a large stone slab about 1.2 meters square, the expedition team found five semicircular arrangements of round holes of different sizes. These round holes are about 3 centimeters deep, and the distance between the holes is about 15 to 20 centimeters. The large round hole is the size of a ping-pong ball, and the small one can be stuffed into two fingers, both the bottom and the perimeter wall are very smooth, and it is obvious that it is the product of artificial carving. The second is the ○|symbol. A protruding yang carving was found on a stone slab, and next to it was a concave yin carving. This is a very important finding, and experts say they can only be seen as symbols. It is possible that a vertical represents the horizon or water, while a circle represents the sun. If the relative position of the vertical and the circle is different, the meaning is completely different.

The third is the face pattern. The face is flattened, with long eyes, a short nose, and a large mouth that is jagged. Among the artifacts unearthed in Lijiashan near Fuxian Lake, there is a portrait of a sorcerer with a mouth also painted in a jagged shape.

The fourth is the sun halo pattern. Two patterns resembling radiating rays of the sun were found on a stone block, similar to those that had appeared on petroglyphs in Cangyuan Wa Autonomous County, Yunnan Province, but on land, and from the Neolithic period 4,000 years ago. This pattern found this time is underwater, is inscribed, has grooves, and represents the rays of the sun, which is more primitive.

Fifth, there is a giant stone high-rise building, that is, an underwater pyramid. Experts estimate that the underwater pyramid may have been a place of worship. The building is very large, 19 meters high and 90 meters long at the base, and it can be clearly seen on the image sonar scan that the building has 5 steps and some signs of fracture. According to reports, the first and second steps of the five steps are composed of sandstone, and the third, fourth and fifth steps are composed of hard bluestone. The main reason for the different materials of the 5 steps of the building is that the sandstone is soft and easy to carve. The various patterns and symbols found so far are found at the first level. Experts deduce that this is entirely a man-made structure, and that it may be related to sacrifices. A tall stepped building is divided into 3 floors, and the basic direction is the traditional north-south direction of ancient China, with high in the east and low in the west. It is divided into 3 floors from east to west, the first step is 10-20 meters from the water surface, the second step is 20-30 meters from the water surface, and the lowest third step is 30-40 meters from the water surface, and the steps are neat and symmetrical. The other stepped building is the most imposing. It has a total of 5 floors, the first floor is 63 meters wide at the bottom, the second floor is 48 meters wide, the third and fourth floors collapse is more serious and cannot be measured carefully, the fifth floor is 27 meters wide, and the whole building is 16.9 meters high, similar to the Mayan pyramid of the Americas, with small steps connected between each of the large steps. In another area, a circular building with a diameter of 47 meters at the base and a high south side with steps can be faintly discerned, with a serious collapse in the north and a gap in the northeast, similar in shape to the Colosseum in ancient Rome. Two tall stepped pyramid buildings and a rotunda are the most important. If it is excavated, it will definitely shock the world, I didn't expect that we also have pyramids in China. ”

I shook my head and said, "But this note says it's an underwater pyramid, and it's definitely not in China, but without further ado, let's practice in the shallow water." Xiaofei said unhurriedly to me: " Sharpening the knife is not a mistake to chop wood, anxious to eat hot tofu, I just looked, diving equipment is readily available, it seems that Mr. Wang for our trip to the deep sea to prepare the equipment is quite sufficient, but these ancients also have to learn the relevant knowledge of deep diving to go into the water, after all, the seabed is not better than the land, the sea water is unfathomable, the following situation is complicated, full of dangers, you must learn the relevant knowledge to be calm, especially Ziyue you, but also study hard, do not slacken. Because everyone else is ancient, Xiao Fei naturally stands up as a teacher and becomes everyone's deep diving teacher. Xiao Fei then took out a piece of cardboard from his bag and said: "Don't worry, I am a professional who holds the CMAS diving instructor certificate, which is produced and issued by the World Diving Federation (CMAS) and is used all over the world. So it's very authoritative, and everyone is optimistic, it's genuine. All of our beginner diving training takes place in shallow water. "I almost burst out laughing, but I still didn't say that this thing was mostly fake, and they were famous, and the famous group of thieves couldn't find anything. Although this certificate is fake, he has real talent after all. Everyone immediately cast admiring glances at Xiao Fei.

Xiao Fei continued, "Everyone is listening attentively now, but we still need time to practice and study hard later." "I've never learned to dive before, and I feel very interested, and I have saved a lot of money on tuition, which is quite cost-effective, and I can't help but concentrate and concentrate on it. Brother Yixiu couldn't help but say disapprovingly: "Who can't dive, I will hold it in one breath, diving him for more than ten meters is completely a piece of cake, easy." There is no need to study at all, it is a waste of time. ”

Xiao Fei smiled and said, "You don't understand this, we're talking about diving with equipment." One of the diving without equipment is snorkeling, and the other is free diving, snorkeling is not dangerous, and the diving depth is not deep, generally within 10 meters, sightseeing-oriented. Freediving is the most dangerous diving activity, challenging the physiological limits of human beings, because there is no decompression, so people often die due to serious diving diseases, the current world record is 124 meters, but it is very dangerous, and the time spent underwater is also limited. Recreational diving and deep-sea diving with equipment, recreational diving at a depth of no more than 60 meters at sea level, no more than 40 meters at high altitude, and a depth of more than 10 meters in the process of decompression, the decompression time is determined by the depth of the dive - this decompression time we look at the tips of the computer watch, the calculation of underwater water pressure is 10 meters as an atmosphere. Deep-sea diving has a special decompression chamber, which can increase the depth of the dive to several hundred meters after having a decompression chamber, and there are still dangers, but there is no free diving, which requires experienced divers to carry out the work. The amount of time a bottle of air can be dived depends on the diver's technique, lung capacity, and depth of dive. Their dive in the deadly abyss should be called cave diving, which is more risky than open water diving, because it is more difficult to escape and has a smaller chance of survival, so the divers who carry out the cave dive must be more than three stars. Submersibles are divided into: hard diving, soft diving, semi-locking loop air supply, on-demand air supply, and self-sufficiency; Diving methods are divided into unsaturated diving and saturated diving. The types of breathing gases are divided into: air diving, nitrogen jujube oxygen mixture, helium jujube oxygen mixture, hydrogen jujube oxygen mixture, and other gas mixtures. Nature: professional diving and recreational diving. Recreational diving, on the other hand, refers to diving activities for the purpose of underwater sightseeing and recreation, which is divided into snorkeling and scuba diving. Snorkeling is relatively simple, just use a mask, snorkel and fins to float on the surface and then watch the underwater landscape through the mask. Snorkeling can be carried out at home and abroad as long as you pass simple training and do not necessarily need to obtain a snorkeling certificate.

What we are learning now is professional diving, which mainly refers to the diving activities that require experienced professional divers in underwater engineering, underwater salvage, underwater exploration, etc. Scuba diving is a type of diving with a compressed air cylinder – not what many people think is the use of an oxygen cylinder and the use of an underwater breathing apparatus to breathe underwater. A full set of scuba diving equipment includes masks, snorkels, fins, respirators, diving instruments, tanks, buoyancy adjustment vests and wetsuits, etc., when we dive in open water, we will also carry diving knives, underwater flashlights and even spearguns and other necessary auxiliary equipment, these things are all available on the UFO, you don't need to worry, I will give you a demonstration later. In particular, you must pay attention to how to breathe in the water, simply put, you breathe with your mouth, not your nose. ”

It seems that Xiao Fei is indeed very professional, but then again, working in such a top-level thief company, this is estimated to be the basic skills that the company's employees must master, Xiao Fei talked endlessly, but also specially for us to find a shallow water to prescribe the right medicine, everyone began to operate seriously according to Xiao Fei's demonstration, I learned well, after all, modern society, professional terms can be understood as soon as you hear it, and you will learn it quickly. Wang Gongzi studied very seriously, he learned twice, and Duan Gongzi learned it, he was really talented and intelligent, worthy of being an outstanding representative of the ancient Song Dynasty, although Brother Yi Xiu was bold, but his learning ability was a little worse, and he learned three times, and the most dull was Hu Jiaojiao, who usually looked clever, but he would not operate at a critical time, and he barely learned it after ten times.

Xiao Fei continued to be elated and swore that "everyone has just listened to my tutorial and mastered the technique, you are equivalent to having a TIPS star diver certificate. Don't underestimate this certificate, TIPS is now popular in the world, and I would like to congratulate you all on successfully passing the diving study and passing the test. Finally, I would like to say that diving is a sport with a strong emphasis on team spirit. Diving is dangerous. Later, we must strictly follow the technical specifications in the diving specifications in the deep sea, the seabed situation is complicated, no matter what situation we encounter, we must be calm and calm at the bottom of the sea. After Xiao Fei's eyebrows danced, he quickly lost no time in starting the take-off saucer, this flying saucer has been unmanned, no need to operate, just enter the destination, Xiao Fei thought about it and entered the Bermuda Triangle this destination, indeed I also feel that this mysterious Bermuda Triangle is more likely to be the submarine pyramid mentioned on the note, at this moment we have no other clues to confirm which pyramid it is, but anyway, this flying saucer is fast, if it is not this submarine pyramid, we will change to other submarine pyramids, and the future will be long。 As we watched with great anticipation, the flying saucer flew quickly in the direction of the Bermuda Triangle.
