Dr. Deng Australian immigrants

I suggest reading Liu's Ground Gun, which contains a discussion on this issue.

Quoted from Liu's "Ground Gun"

…………

According to legend, in the middle of last century, after learning that China's first nuclear test was completed, Mao Zedong's first question was: "Is that a nuclear explosion?" I don't know whether it is intentional or unintentional, but this question is actually very expert. The key technology of fission nuclear bomb is centripetal compression. When a nuclear bomb is detonated, the fissile material is compressed into a compact sphere by the explosive force of conventional explosives wrapped around it, reaching the critical density, triggering a severe chain reaction and producing a nuclear explosion. All this will happen in a millionth of a second, and the centripetal compression of fissile material must be extremely accurate. Even the smallest centripetal pressure imbalance may blow up the fissile material before it reaches the critical density. In that case, what happened was just an ordinary chemical explosion. Since the birth of nuclear weapons, researchers have designed various shapes of compressed explosives with complex mathematical models. In recent years, they have tried to obtain accurate centripetal compression by various means with the latest technology. "Sugar coating" is one of such technical ideas.

Sugar coating is a kind of nanometer material. When making fission bombs, people wrap nuclear explosives with "sugar coating", and then wrap a layer of conventional explosives outside the "sugar coating". "Sugar coating" has the function of automatically balancing and distributing the surrounding compressive stress. Even if the compressive stress produced by the explosion of the outer explosive is uneven, the nuclear explosive wrapped by it can still be compressed accurately centripetally through the balanced distribution of the "sugar coating" stress.

Shen Huabei said: "The white sphere you see surrounded by eight nuclear warheads is an alloy material coated with sugar, which will be subjected to great centripetal pressure in a nuclear explosion. This is a study that we plan to carry out during the whole destruction process. After all, this is a rare opportunity: when all the nuclear bombs disappear, it is difficult to produce such a large instantaneous compressive stress on the earth in a short time. It will be interesting to test what the material will become and what will happen under such a great centripetal pressure. We hope that through this research, we can find the bright future of' sugar coating' technology in the civil field. "

A UN official said: "You should put graphite in the' sugar coating' so that we can get a big diamond every time we explode, and the costly nuclear destruction project may become profitable."

Hearing a few laughs in the earphone, officials without technical background are always despised on this occasion. "The pressure generated by the 800,000-ton nuclear explosion is many orders of magnitude greater than the pressure to convert graphite into diamond." Some people say.

Shen Yuan's bright children's voice suddenly sounded in everyone's headphones: "Of course, the Big Bang didn't produce diamonds. Let me tell you what it is: it's a black hole! A little black hole! It will suck us all in, suck the whole earth in! Through it, we will drill into a better universe! "

"Ha ha, son, the pressure of this nuclear explosion is too small ... Dr. Shen, your son's small head is really unusual!" Kevinsky said: "What about the test results? What did that alloy become? I don't think you can find it? "

"I don't know yet. Let's go and have a look. " Shen Huabei pointed to the front and said. The nuclear explosion made the huge hole in a regular spherical shape, so the bottom of the hole was a small basin. In the middle of the basin in the distance, several headlights shook. "That's from the sugar-coated experimental project team."

Everyone walked towards the center of the basin, and it felt like walking down a long hillside. At this time, Kevinsky suddenly stopped, then squatted down and put his hands on the ground. "There is vibration underground!" "

Others felt it, too. "It won't be an earthquake induced by a nuclear explosion, will it?"

Zhao shook his head: "The geological structure in the area where the destruction site is located has been repeatedly investigated, and it will never induce an earthquake. This vibration is not an earthquake. It appeared after the explosion and has continued to this day. Dr. Deng Wenyi said that it is related to the' sugar coating' test. I don't know the specific situation. "

As they approached the center of the basin, the vibration from the depths of the stratum gradually increased until the soles of the feet were numb, as if a rough wheel was spinning wildly in the depths of the earth. When they came to the center of the basin, one of a small group of people stood up. He is Deng mentioned by Zhao just now, the person in charge of the nuclear explosion compression test project of materials.

"What's that in your hand?" Shen Huabei asked, pointing to a mass of white things in Deng's hand.

"fishing line." As he spoke, Dr. Deng and the group of people squatting in a circle on the ground stared at a small hole in the ground. This hole appears on the surface of melted and condensed rock, with a diameter of about 10 cm and a very regular circle. The edge is very smooth, like a hole drilled by a drill. Zheng Yiwen's fishing line is constantly being put into the hole. "You see, more than ten thousand meters have been put, which is far from the bottom. After radar detection, this hole is more than 30,000 meters deep and is still extending. " "How did you come?" Someone asked. "The compressed test alloy emerged, and it sank into the stratum, just like a stone sinking on the sea. This vibration is transmitted when passing through dense strata. "

"God, this is a miracle!" Kevinsky exclaimed, "I thought the alloy was just evaporated by the high temperature of the nuclear explosion." Deng said: "If there is no icing, it will be like that, but this time it will be compressed into a new material form by the centripetal pressure of icing, and then it will be evaporated. It is more appropriate to call it supersolid, but we already have this name in physics, so let's call it a new solid. "

"You mean, the specific gravity of this thing is compared with the specific gravity of formation rocks, just like the specific gravity of stones and water?" "Much bigger than that. The main reason why stones sink in water is not the specific gravity, but because water is liquid-the specific gravity of water does not change much after freezing, but the stones placed on it will not sink. Now the new solid matter actually sinks in the solid rock, which shows how amazing its density is! "

"You mean it turned into neutron star matter?"

Deng shook his head: "We haven't measured it accurately, but what is certain is that its density is much smaller than the degenerate matter of neutron stars, which can be seen from its sinking speed. If it is really neutron star material, it will sink into the stratum like a meteorite falling into the atmosphere, causing volcanic eruptions and major earthquakes. It is a material form between ordinary solid state and degenerate state. "

"Will it sink into the center of the earth?" Shen Yuan asked.

"Maybe, son, because after sinking to a certain depth, the stratum material will become liquid, which will be more conducive to its sinking!"

…………

Antarctic courtyard "imaginative people are often helpless in the cold." On the contrary, those who grasp the historical trend in reality have only a brain with poor imagination. " Your son, on the other hand, is one of the few people in history who combined the two. Many times, reality is just an island in his fantasy ocean, but if he wants, he may turn his world over at any time, making fantasy an island and reality an ocean. He is the best sailor in two oceans ... ""I know my son, so you don't have to waste time on it. " Shen Huabei interrupted Deng Yang.

"But you wouldn't think how high Shen Yuan climbed in reality and how much power he had, which enabled him to turn his most abnormal fantasy into reality. It's a pity that society didn't find this danger early. There may have been people like him in history, but like asteroids that grazed the earth, they all disappeared into the vast space without releasing energy in this world. It's a pity that history gave your son a chance to create disaster with abnormal fantasy.

"In the fifth year after you entered hibernation, the world's competition for the Antarctic continent has achieved initial results: this continent has been identified as a region of global development, but all major countries have won a large exclusive economic zone for themselves. It is the only hope for major countries to get rid of the economic recession caused by environmental problems and resource depletion to make themselves prosperous in the economic zone of the Antarctic continent as soon as possible.' The future is above the earth' became a well-known slogan at that time. " Just then, your son put forward that crazy idea, claiming that the realization of this idea would turn the Antarctic continent into the yard of this country, and it would be more convenient to go to the South Pole from Beijing than from Beijing to Tianjin. This is not a metaphor, but it is true that the travel time is shorter than that of Tianjin, and the energy consumption and pollution are less than that of Tianjin. At the beginning of that famous TV speech, the audience all over the country laughed as if watching a farce, but they soon quieted down because they found that the idea really worked! This is the idea of the Antarctic courtyard, and then a disastrous Antarctic courtyard project began based on it. "

Speaking of which, Deng Yang was inexplicably silent.

"Go on, what's the idea of the Antarctic courtyard?" Shen Huabei urged.

"You will know." Deng Yang said coldly.

"Then can you at least tell me what all this has to do with me?"

"Because you are Shen Yuan's father, isn't it very simple?"

"Is bloodline popular again?"

"Of course not, but your son's numerous confessions make bloodline theory suit you. When he became world-famous, he sincerely claimed that most of his thoughts and characters were formed from his father before he was eight years old, and the following years only supplemented some knowledge details. He also said that the original creator of the Antarctic courtyard idea was also his father. "

"What? ! Me? Antarctica ... Courtyard? ! This is simply ... "

"Let me finish the last point: you also provided the technical foundation for the Antarctic courtyard project."

"What do you mean? ! "

"Of course, it is a new solid material. Without it, the idea of the Antarctic courtyard is just a dream. With it, this abnormal fantasy immediately becomes a reality. "

Shen Huabei shook his head in confusion. He really can't imagine how the ultra-high density new solid materials turned the Antarctic continent into the courtyard of this country.

At this moment, the car stopped.

= = = = = = = = = = = = = = = = = = 4. After getting off at the ghost gate, Shen Huabei saw a strange hill. The mountain is a single rust color, and no grass can be seen. Deng Yang tilted his head to the hill and said, "This is an iron mountain." Seeing Shen Huabei's surprised eyes, he added, "It's just a big piece of iron." Shen Huabei looked around and found several such iron mountains nearby, standing abruptly on this vast plain with strange colors, giving people a strange scenery.

Shen Huabei can walk now. He and the gang staggered towards a tall building in the distance. The building is a perfect cylinder, hundreds of meters high, with a smooth surface and no openings. As they approached, they saw a heavy iron gate sliding to one side, revealing an entrance. A group of people came in and the door closed tightly behind them.

In the dim light, Shen Huabei saw them in a place like a sealed cabin. On the smooth white wall hung a long row of sealed suits like spacesuits. People take off a sealed suit from the wall and put it on. With the help of two people, he began to put on one of them. In the process, he looked around and saw a closed sealed door opposite. There is a red light on the door, and there is a luminous digital display next to it. What he saw was atmospheric pressure. When his heavy helmet was tightened, a transparent liquid crystal display area appeared in the upper right corner of the mask, showing rapidly changing numbers and graphics. He only saw that it was the self-inspection of each system inside the spacesuit. Then, he heard a low hum outside, as if something had started, and then noticed that the air pressure displayed above the opposite door was rapidly decreasing, and it dropped to zero after about three minutes. The red light next to it turned green, and the door opened, revealing the darkness inside the sealed building.

Shen Huabei confirmed his guess: this is a transition cabin from atmospheric zone to vacuum zone, so the interior of this huge cylinder is vacuum.

A group of people walked into the entrance and the door closed behind. They were in the thick darkness, and the lights on several people's helmets were on, and several beams of light appeared in the darkness, but they could not shine far. A familiar feeling appeared, and Shen Huabei couldn't help shivering, and there was an inexplicable fear in his heart.

"Go ahead." Deng Yang's voice rang out from the headphones. The halo of the headlights reflects a small bridge in front, less than one meter wide, and the other end extends into the darkness. It is unclear how long it is, and the bridge is dark. Shen Huabei stepped onto the small bridge with trembling legs, and his heavy leather boots made a hollow sound on the thin iron deck. He stepped out of a few meters and looked back to see if the people behind him had caught up. At this time, everyone's headlights went out at the same time, and the darkness swallowed everything. But it only lasted for a few seconds, and blue light suddenly appeared under the bridge. Shen Huabei turned around, only he got on the bridge, and everyone else crowded around the bridge and looked at him. In the blue light from the bottom up, they look like a group of ghosts. He looked down at the railing by the bridge, and the fear of blood coagulation almost seized him.

He stood on a deep well.

The diameter of this well is about ten meters, and there is a round hole on the wall at regular intervals, indicating that there is a deep well in the dark. He is standing in the middle of a small bridge across the wellhead. Seen from here, the well is bottomless, and countless gaps on the shaft wall gradually shrink until they become a little bit. He seems to be looking down at a big target with blue light.

"Now start the trial and pay back what your son owes!" Deng Yang said loudly, and then turned a wheel installed at the bridgehead with his hand, muttering "For my abused youth and talent ..." The bridge tilted at an angle, and Shen Huabei grabbed the railing on the other side and tried to stand firm.

Then Deng Yang gave the wheel to the orphans left by the central fracture disaster, and they also turned hard: "Give me my melted mom and dad ..." The inclination angle of the bridge increased a little.

The wheel was passed to the orphan girl left by the bolt loss disaster. The girl glared at Shen Huabei and turned the steering wheel hard: "For my evaporated mom and dad ..."

The attempted suicide man who lost all his wealth grabbed the steering wheel from the orphan girl left by Bolt's loss disaster: "For my money, my Rolls Royce and Lincoln, my beach house and swimming pool, for my ruined life, for my wife and children who queued up for relief in the cold street ..." The bridge has turned 90 degrees, and Shen Huabei can only sit under the railing with both hands.

The man who suffered from schizophrenia because he lost all his wealth also scrambled to turn the wheel with the man who tried to commit suicide because he lost all his wealth. His illness is obviously not good enough, and he didn't say anything, just smiled at the deep well below. The bridge was completely overturned, and Shen Huabei hung upside down above the deep well with both hands grasping the railing.

At this point, he doesn't have much fear. He looked at the bottomless gate of hell at his feet, and his short life flashed in his mind like lightning: childhood and adolescence were gray, and I couldn't remember how much happiness and happiness there were in those times: after going to society, he succeeded academically and invented the "sugar-coated" technology, but he didn't let life accept him; He struggled in the spider web of interpersonal relationship, but it became more and more entangled. He has never really experienced love, and marriage is just a last resort. When he made up his mind never to have children, children came into this world ... He is a person who lives in his own world of thoughts and dreams, an alternative that most people hate, and he can never really blend in with the crowd. His life is always lonely, sailing against the current. He once had hope for the future, but this is the future: his dead wife, his son who has become a public enemy of mankind, polluted cities, and these hateful perverts. It turned out that he made up his mind to know the truth before he died. It doesn't matter now. He is a tired walker, and his only desire is liberation.

In the cheers of the group of people at the well, Shen Huabei let go of his hand and fell to his destiny goal with blue light.

He closed his eyes and was immersed in the weightlessness of falling. His body seems to have become transparent, and all the unbearable weight in life has left him. In the last few seconds of his life, a song suddenly sounded in his mind. That is an old Soviet song taught by his father. No one could sing this song before his hibernation. Later, he went to Moscow as a visiting scholar, hoping to find a bosom friend, but this song was also lost in Russia, so it became his own song. Before reaching the bottom of the well, he could only sing one or two notes in his heart, but he believed that when his soul finally left his body, the song would continue in another world ... Unconsciously, the slow-paced song in the middle had been sung in his heart for a long time. At this moment, his consciousness suddenly woke up. He opened his eyes and saw himself constantly passing through one blue halo after another.

The decline continues.

"Ha ha ha ha ....." Deng Yang's laughter rang out from the headphones. "Dying people feel good, don't they? ! "

He looked down and saw a series of concentric circles with blue light. He kept crossing the largest circle, and a new small circle appeared in the center of the circle and expanded rapidly. Looking up, it is also concentric circles, but its movement is the reverse of the previous picture.

"How deep is this well?" He asked.

"Rest assured, you will always come to an end. The bottom hole is a hard and smooth steel plate. With a beep, the patties you smashed in will be thinner than paper! Ha ha ha ha ... "

At this time, he noticed that a red line appeared in the LCD area in the upper right corner of the mask: you have reached the depth 100 km and the speed 1.4 km/s, and you have crossed the Moho surface. From the crust to the mantle.

Shen Huabei closed his eyes again. This time, there was no Song in his mind, but he was thinking as quickly as a cool computer. When he opened his eyes again half a minute later, he understood everything: this is the Antarctic courtyard project. Hard and smooth bottom steel plate does not exist, and this well has no bottom.

This is a tunnel that runs through the earth.

Verb (abbreviation for verb) big tunnel "is it tangent or through the center of the earth?" Shen Huabei asked, just thinking in the form of language.

"Smart mind, thought of it so quickly!" Deng Yang sighed.

"Much like his son." Someone followed, which sounded like an orphan left by the central rupture disaster.

"It passes through the center of the earth, from Mohe in China to the Antarctic Peninsula in the easternmost part of the Antarctic continent." Deng Yang answered Shen Huabei.

"Is that city Mohe just now? ! "

"Yes, it flourished as the starting point of the earth tunnel."

"As far as I know, crossing the earth from there should reach southern Argentina. Yes, but the tunnel is a little bent. "

"Since the tunnel is curved, will I hit the wall?"

"If the tunnel goes straight to Argentina, you will definitely hit it. That kind of straight earth tunnel can only be realized on the earth axis running between the poles. This tunnel with a certain angle to the earth axis must consider the rotation factor of the earth, and its bending just allows you to pass smoothly. "

"Oh, great project!" Shen Huabei sincerely praised.

You have reached the depth of 300 meters. P~。 T, the speed is 2.4 ~ a "-I/S. It has entered the mantle viscous material area.

He saw that his frequency of passing through the aperture was accelerating and the density of the upper and lower concentric circles increased a lot.

Deng Yang said: "Building a tunnel through the earth is not a new idea. In the eighteenth century, two people put forward this idea. One is the mathematician Mobutu, and the other is the world-famous Voltaire. Later, the French astronomer Fran Marion put forward this plan again, and first considered the factors of the earth's rotation ... "

Shen Huabei interrupted him and asked, "Then how do you say that this idea came from me?"

"Because those people in front were just doing thought experiments, and your thoughts influenced a person, who later used his demonic talent to promote the realization of this fantasy."

"But ... I don't remember mentioning this to Shen Yuan."

"What a forgetful person. You put forward an idea that later changed the course of human history, but you forgot it. "

"I really can't remember."

"Then you can always think of the Argentine named Becado and the birthday present he gave your son?"

You have now reached the depth of 1 500 km, the speed of 5. 1 km/s, and entered the rigid matter area of the mantle.

Shen Huabei finally remembered. It was Shen Yuan's sixth birthday, and Shen Huabei invited Dr. Becado, an Argentine physicist in Beijing, to be a guest at home. At that time, the top two countries in South America had risen. Argentina claimed a large area of land on the Antarctic continent, immigrated to Antarctica in large numbers, and rapidly developed nuclear weapons, which shocked the whole world.

In the subsequent process of global denuclearization, Argentina, as a nuclear power, naturally joined the United Nations Destruction Committee, and Shen Huabei and Becado were experts in a technical group of this Committee.

At that time, the gift that Begado brought to Shen Yuan was a globe. It is made of the latest glass material, which reflects the rapidly developing technical level in Argentina. Its refractive index is the same as that of air, so there is no glass ball. The continents on the earth seem to hang between the poles. Shen Yuan likes this gift very much.

In the chat after dinner, Becado took out a China newspaper and showed Shen Huabei a political cartoon on it, which showed an Argentine star kicking the earth.

"I don't like it," Begana said. "China people's understanding of my country seems to be limited to football, and this understanding has extended to international politics. In your eyes, Argentina has become an aggressive country. "

"You know, after all, Argentina is the farthest country from China on earth, and you are opposite the earth." Zhao said with a smile and took the fully transparent globe from Shen Yuan. On it, China and Argentina are overlapped by a super transparent sphere.

"Actually, I have a way to make the two countries communicate better," said Shen Huabei, taking over the globe. "Just dig a tunnel from China through the center of the earth."

Begana said: "That tunnel is also more than 12 thousand kilometers long, which is not much shorter than the plane route."

"But the travel time will be much shorter. Think about jumping in from this end of the tunnel with a travel bag ... "

Shen Huabei's original intention is to change the topic from politics. He succeeded, and Begana became interested: "Shen, your way of thinking is always different ... let me see: I will keep accelerating after I jump in." Although my acceleration will decrease with the increase of falling depth, it will indeed accelerate all the way to the center of the earth. When I pass through the center of the earth, my speed will reach the maximum and the acceleration will be zero; Then I start to slow down and rise, and the value of this deceleration will increase with the rise. When I reached Argentina on the other side of the globe, my speed was exactly zero. If I want to go back to China, I just need to jump off that plane again. If I want, I can do eternal simple harmonic vibration between the northern and southern hemispheres. Well, it's wonderful, but the travel time ... "

"Let's do the math." Shen Huabei turns on the computer.

The calculation results will come out soon. Under the ideal average density of the earth, it takes 42 minutes 12 seconds to jump into the earth tunnel from China, cross the earth with a diameter of more than 12000 km, and land in Argentina.

"Travel quickly!" Begana said happily.

You have now reached 2800 &; "Depth, speed of 6.5 km/s, you are crossing the Gutenberg discontinuity. Enter the core.

Shen Huabei, who was stumbling, heard Deng Yang say again, "That night, you must not have noticed that your son was staring at those big eyes full of aura and listening to your words with rapt attention. You can't even know that he stared at the transparent earth by the bed all night. Of course, you may have influenced your son countless times. You have planted many seeds of fantasy in Shen Yuan's mind, and this is just one of the flowers. "

Shen Huabei stared at the rapidly rising shaft wall four or five meters away from himself, and the high frequency coming from around the aperture blurred the surface of the shaft wall.

"Is this a new solid material?" He asked.

"What else can it be? What other materials have the strength to build such a tunnel? "

"How did such a huge amount of new solid matter come into being? How to deal with and process this material with a large specific gravity that can sink into the stratum? "

"It can only be said in the simplest way: continuous small nuclear explosions produce new solid substances. The core technology is of course your' sugar coating', and its production line is huge and complicated; New solid materials have many density grades, and materials with lower density will not sink into the stratum. Use it to build a large area foundation, put high-density materials on it, and its pressure will be dispersed by the foundation, so it can float on the ground. Using similar principles, this material can also be transported. As for the processing of new solid materials, the technology is more complicated and may be beyond your knowledge. In a word, the new solid material is already a huge industry, and its economic scale exceeds that of steel. It is not only used for the Antarctic courtyard project. "

"So how was this tunnel built?"

"First of all, let me tell you something: the basic component of tunnel construction is well circles, and each well circle is about 100 meters long. The whole tunnel consists of about 240,000 well circles. As for the specific construction process, you are a smart person, maybe you can figure it out yourself. "

You have now reached a depth of 4 100 km and a speed of 7.5 km/s, which is in the middle of the liquid core.

"open caisson?"

"Yes, it is open caisson technology. First, the well circle is sunk into the stratum from China and South Pole, and spliced into a line running through the earth. Step 2, take out the stratum material in the spliced well circle to form the tunnel. The iron mountain you see outside the tunnel entrance is an iron-nickel alloy drawn from the core of the tunnel. The specific construction depends on the underground ship. This kind of machine which can travel in the stratum is also made of new solid materials. Some models can travel deep in the core, and they can locate the open caisson circle in the stratum. "

"In this way, only120,000 wells are needed."

"supersolid materials under the pressure of the deep earth and high temperature is no problem, but there are many fluids underground, shallow is flowing magma. What is more dangerous is that the liquid iron-nickel flow in the core has a huge shear impact on the tunnel. The strength of new solid materials can withstand this impact, but the connection between wells is not. Therefore, the tunnel consists of two layers of wells, the inner well circle is close to the outer well circle, and the two layers of wells are staggered, so that

You have now reached 5400 &; ~ Li depth, speed 7.7 km/s, close to the solid core.

"Next, I think you should tell me something about the disaster caused by the Antarctic courtyard project."

= = = = = = = = = = = = = six. Disaster "The first disaster of the Antarctic courtyard project occurred twenty-five years ago, when the project entered the final stage of exploration and design, requiring a lot of underground navigation. On an expedition, an underground spaceship named "Sunset Six" crashed into the mantle and sank into the core. Two of the three crew members on board were killed, and only one young female pilot survived. She is still imprisoned in the earth's core and will spend the rest of her life in a narrow underground spaceship. The neutrino communication equipment on that ship has lost its transmitting function, but it may still receive it. That's right: her name is Shen Jing and she is your granddaughter. "

Shen Huabei's heart twitched.

At this crazy speed, the cracks on the shaft wall have become an organic whole in Shen Huabei's eyes, making the shaft wall of this giant well emit harsh blue light. Shen Huabei, which is falling rapidly, seems to be crossing just a visit and entering a past that is not far away but has never been experienced.

You have now reached the depth of 5800~ "Li, the speed is 7.8 km/s, and you have entered the solid core. Close to the center of the earth!

"In the sixth year of the Antarctic courtyard project, a tragic central fracture disaster occurred. As mentioned earlier, the tunnel consists of two layers of wells that are interlaced with each other. During the installation of the inner well, the J~'-F substance in the connected outer well must be hollowed out first, so as to avoid mixing impurities between the two wells and affecting the sealing performance between the two wells. In the construction, the technology of hollowing out a section of outer well ring and putting it into a section of inner well ring is adopted, that is, during the construction of the core section, when the outer well ring is hollowed out and the inner well ring is not in place, the two outer well rings, including the joint, will bear the impact of iron and nickel flow in the core separately. Originally, the joint of the two sections of well rings adopted very strong riveting technology, which should be able to withstand the impact of iron-nickel flow for a long time in design. However, more than 490 kilometers into the core, there is an unusually strong iron-nickel flow in two newly hollowed oil wells, and its speed is five times the highest speed observed in a large number of previous explorations. The strong impact force dislocated the two well circles, and the core material with high temperature and high pressure suddenly poured into the tunnel and rose rapidly along the completed tunnel. After learning of the fracture, Shen Yuan, as the chief engineer of the project, immediately ordered the closure of the security door located on the discontinuous surface of Gutenberg, which was called Gutenberg Gate. At this time, more than 2,500 engineers are under construction in the tunnel nearly 500 kilometers under the gate. After learning of the fracture, they also evacuated by high-speed elevator in the tunnel. * * * There are more than 130 elevators, and the last elevator keeps a distance of about 30 kilometers from the rising iron-nickel flow along the tunnel. In the end, only 6 1 elevator had time to pass the Gutenberg gate, and the rest were swallowed up by the core flood with the temperature exceeding 4000 degrees after the gate was closed, and 1527 people were buried in the center of the earth.

"The central rupture disaster shocked the whole world, and Shen Yuan was strongly condemned by two sides at the same time: one side thought that he could wait until all the elevators passed through the Gutenberg gate before closing it. At this time, the flow of iron and nickel is still 30 kilometers away from the gate. Although the time is short, it is still in time. Even before the gate was closed, there was a safety door on the Moho surface (the interface between the surface and the mantle)-Mohoven. The extremely angry victim's family accused Shen Yuan of intentional homicide. In this regard,
