The school is moving into the dungeon, and we are the first residents to do so. The school bus drilled into a tall tunnel that sloped into the ground. After walking for half an hour, we were told that we had entered the city, but what did it look like outside the car window? We could only see the intricate branch holes and the countless sealed doors on the walls of the caves, and under the row of floodlights on the high ceiling of the cave, everything was a monotonous metallic blue. The thought of spending most of the rest of our lives in this world makes us sad.

"Primitive man lived in a cave, and we lived in a cave again. Ling'er whispered, and Teacher Xiaoxing heard this.

"There is no way, children, the environment on the ground will soon become very terrible and terrible, at that time, when it is cold, spit on a mouthful, before it falls to the ground, it will freeze into Xiaoice lumps; when it is hot, spit again, before it falls to the ground, it will become steam!"

"I know it's cold, because the earth is getting farther and farther away from the sun, but why is it still hot?" asked a junior doll in the same car.

"Stupid, haven't you learned to change orbit and accelerate?" I said angrily.

"Nope. ”

Ling'er patiently explained, as if to distract from the sadness just now. "That's right: unlike what you think, the earth engine is not so powerful, it can only give the earth a small amount of acceleration, it can't push the earth out of the sun's orbit all at once, and before the earth leaves the sun, it has to circle it 15 times!

Now, the earth revolves in a very round circle around the sun, but the faster it goes, the flatter the circle, the faster and the flatter the flatter the sun goes, so later, the earth will sometimes be far away from the sun, of course it will be cold......"

"Yes...... The earth is very cold to the farthest part, but at the other end of the flat circle, it is ...... from the sun Well, I think about it, according to orbital dynamics, it's still so close now, how can it be hotter?"

What a little genius, memory genetic technology makes such a little doll an ordinary person, which is the luck of human beings, otherwise, a miracle like the earth engine that even the gods dare not think of will not become a reality in four centuries.

I said, "But there are still earth engines, little fool, and now, with more than 10,000 of those blowtorches running at full power, the earth has become a retainer for the rocket vents...... Be quiet, I'm upset!"

This is how we began to live underground, with cities like this, with more than a million people 500 meters underground, spread across all continents. In such a dungeon, I finished primary school and moved on to secondary school. School education is focused on science and engineering, and education such as art and philosophy has been reduced to a minimum, and human beings have no such leisure. This is the busiest time for mankind, and everyone has a job to do. Interestingly, all the religions on earth disappeared overnight, and people now finally understand that even if there is a God, he is a bastard. There are still history lessons, but the history of pre-solar age humans in textbooks is to us like a myth in the Garden of Eden.

My father was a low-Earth orbit astronaut in the Air Force and spent very little time at home. I remember that in the fifth year of the orbit change, when the earth was at aphelion, my family went to the beach once. The day when the planet reaches the top of aphelion is a holiday like New Year's Day or Christmas, because at this time the Earth is farthest from the Sun, and people have an illusory sense of security. As we used to go to the ground, we had to wear hermetically sealed heating suits with nuclear batteries. Outside, the dazzling pillars of the earth's engines are the main thing that can be seen, and the rest of the surface world is submerged in the glare of the pillars of light, and there is no change to be seen. We flew for a long time in a flying car, to a place where the beam of light could not shine, to the seashore where we could see the sun. The sun was the size of a baseball, hanging motionless in the sky, its light reflecting only a circle of dawn light around itself, the sky a dark dark blue, and the stars still visible. As far as the eye can see, there is no sea, and in front of you is a white ice field. On this frozen sea, there are large groups of revelers. The fireworks opened in the dark blue sky, the people on the frozen sea were partying with an abnormal feeling, there were drunk people rolling on the ice everywhere, and more people were singing different songs hoarsely, all trying to suppress others with their voices.

"There's nothing wrong with everyone desperately trying to live the life they want to live. Dad suddenly remembered something, "Heh, I forgot to tell you that I am in love with Li Xing, and I am leaving you to be with her." ”

"Who is she?" asked Mom calmly.

"My elementary school teacher. I answered for my father. It's been two years since I entered middle school, and I don't know how my dad and Mr. Xiaoxing met, maybe at that graduation ceremony two years ago?

"Then you go. Mom said.

"I'm going to get tired of it after a while, and I'll be back then, you see?"

"If you want to, of course. Mom's voice was as steady as the frozen sea, but she quickly became excited, "Ah, this one is so beautiful, there must be a holographic scatterer in it!" she pointed to a firework that had just opened in the air, and praised sincerely.

In this day and age, people are baffled when they watch movies from four centuries ago, and they don't understand how people in the pre-solar age could pour so much emotion into matters that are not a matter of life and death. When seeing the heroes and heroines agonizing or crying for love, their amazement is indescribable. In this day and age, the threat of death and the desire to escape are overwhelming, and nothing can really catch their attention and move them except the current state of the sun and the position of the earth. This highly focused attention has gradually fundamentally changed the psychological state and spiritual life of human beings, and they only glance at things like love with their peripheral eyes, like gamblers who catch a few seconds between staring at the roulette wheel and drink their saliva.

After two months, Dad really came back from Teacher Xiaoxing, and Mom was not happy or unhappy.

Dad said to me, "Li Xing has a good impression of you, she said that you are a creative student. ”

Mom looked dazed: "Who is she?"

"Teacher Xiaoxing, my elementary school teacher, Dad has been with her for the past two months!"

"Oh, I remember!" Mom shook her head and laughed, "I'm not yet forty, and my memory is like this." ”

She looked up at the holographic starry sky on the ceiling, and then at the holographic forest on the four walls, "It's good for you to come back, change these images, my children and I are tired of seeing them, but we won't adjust this play." ”

When the earth was falling towards the sun again, my family forgot about it.

One day, the news reported that the sea was melting, so my family went to the beach again. This is when the Earth passes through the orbit of Mars, and according to the amount of sunlight at this time, the temperature of the Earth should still be very low, but due to the influence of the Earth's engine, the temperature on the ground is just right. It's nice to be able to go to the ground without wearing a heating suit or a cooling suit. The sky in this hemisphere where the Earth engine is located is still the same, but when you reach the other hemisphere, you really feel the approach of the sun: the sky is a clear pure blue, and the sun is as bright in the sky as it was before it set sail. But we could see from the air that the sea had not melted, it was still a white ice field. As we stepped out of the flying car in disappointment, we heard an earth-shattering rumble that seemed to come from the deepest part of the planet, as if the Earth was about to explode.

"It's the sound of the sea!" said Dad, "because the temperature rises sharply and the thick ice is heated unevenly, much like an earthquake on land." ”

Suddenly, a thunderous and shrill sound was inserted into the low rumble, and the people behind us who were watching the sea cheered. I saw a long crack in the surface of the sea, and it cracked as fast as a black lightning bolt suddenly appeared on a vast ice field. Then, with a loud bang, such cracks appeared one after another on the sea ice, and the sea water erupted from all the cracks, forming rapids that spread rapidly on the ice sheet......

On the way home, we saw the long-barren land, where weeds were burrowing out of the ground, flowers were blooming, and young leaves were cloaking the dead forest...... All life is seizing the time to rejuvenate.

As the distance between the earth and the sun gets closer and closer, people's hearts are also tightening day by day. Fewer and fewer people came to the surface to admire the spring colors, and most of them took refuge deep in the dungeons, not to escape the impending heat, torrential rains and hurricanes, but to escape the fear of the sun getting closer. One day, after I fell asleep, I heard my mother whisper to my father, "Maybe it's really too late." ”

Dad said, "There were also such rumors during the first four perihelions. ”

"But this time it's true, I heard it from Mrs. Chandler, and her husband is the astronomer of the Navigation Committee, and you all know him. He told her that he had observed an acceleration in the accumulation of helium. ”

"Listen, dear, we must have hope, not because it really exists, but because we are to be noble. In the pre-solar era, to be a noble person you had to have money, power, or talent, but today as long as you have hope, hope is the gold and jewel of this age, no matter how long you live, we must have it! ”

Like all people, I was distraught with the arrival of perihelion. One day after school, I unconsciously walked to the central square of the city, and stood by the circular pool with a fountain in the center of the square, sometimes looking down at the blue water, sometimes looking up at the fantastic ripples of light on the dome of the square, which was reflected by the water. At this time, I saw Ling'er, who was holding a small bottle and a small tube, blowing soap bubbles. With each bunch of blows, she stared blankly at the bubbles floating in the air, watching them disappear one by one, and then blowing out another bunch of ......

"Is it fun to do this when you're so old?" I asked her.

Ling'er was overjoyed when she saw me: "Let's go on a trip!"

"Travel, where are you going?"

"The ground, of course!" she waved her hand in the air, flicking a holographic image of a sunset beach with the computer on her wrist. The breeze blows palm trees, the waves are white, and there are couples on the golden sand, and they are in black silhouettes in front of the sea covered with broken gold. "This is Mona and Da Gang sent back, they are still all over the world, they said it's not too hot outside, it's good outside, let's go!"

"They had just been expelled from school for truancy. ”

"Hmph, you're not afraid of this at all, you're afraid of the sun!"

"Aren't you afraid? Don't forget that you've seen a psychiatrist because you're afraid of the sun. ”

"But I'm different now, I've been enlightened!" Look," Ling'er blew a string of soap bubbles through a small tube, "stare at it!" she said, pointing to a soap bubble.

I stared at the bubble and saw the waves of light and color on its surface, which were surging with a complexity and delicacy that human senses could not grasp, as if the bubble knew the length of its life, and frantically interpreted the countless dreams and legends of its vast memories to the world. Soon, the rag of light and color disappeared in a silent explosion, and I saw a small patch of water vapor that seemed to exist for half a second, and then there was nothing, as if nothing had ever existed.

"See, the earth is just a little blister in the universe, snap, there's nothing, what's there to be afraid of?"

"No, it has been calculated that it will take at least a hundred hours for the earth to completely evaporate at the time of the helium flash. ”

"That's the most terrifying part!" Ling'er shouted, "We are 500 meters underground, like the meat in a pie, we are slowly roasted first, and then evaporated!"

A chill spread through my body.

"But it's different on the ground, where everything is evaporated in an instant, and the people on the ground are like bubbles, snapping...... Therefore, it is better to be on the ground when helium flashes. ”

For some reason, I didn't go with her, she went with Adong, and I never saw them again.

The helium flash did not occur, and the Earth passed perihelion at high speed, rising to aphelion for the sixth time, and people's tense nerves relaxed. Since the Earth's rotation has stopped, on this side of the Sun's orbit, the Earth's engine on the Asian continent is running in its direction, so it stops before passing perihelion, and only occasionally makes some attitude adjustments, and we are in the quiet and long dark night. The engines on the American continent run at full power, which becomes the retainer of the rocket vent. Since the sun was also in the Western Hemisphere at this time, the heat there was even more terrifying, and the grass and trees were smoking.

In this way, the Earth's orbit change is accelerating year after year. Whenever the earth rises toward aphelion, people's hearts relax as the distance between the earth and the sun increases, and when it falls towards the sun in the new year, people's hearts tighten day by day. Every time we reach perihelion, rumors spread in the community that the helium flash of the sun is about to take place at this time, and it is not until the earth rises again to aphelion that people's fears subside with the dimming sun in the sky, but the next fear is brewing...... The human spirit is like swinging a cosmic swing, or more appropriately, experiencing a cosmic Russian roulette: the rise to aphelion and the fall to the sun are turning the magazine, and the passing perihelion is pulling the trigger! The nerves at each pull are more tense than the last, and I spent my teenage years in this alternating fear. In fact, if you think about it carefully, even at aphelion, the earth has not left the power circle of the sun's helium flash, and if the sun erupts at that time, the earth will be slowly liquefied instead of being vaporized, and that result is really not as good as at perihelion.

In the Age of Escape, great catastrophe ensued.

Due to the acceleration generated by the Earth engine and the change of orbit, the balance of the iron-nickel core in the Earth's core is disturbed, and its influence passes through the Gutenberg discontinuity and spreads to the mantle. Geothermal escaping and volcanoes are rampant on various continents, which is a deadly threat to human underground cities. Since the sixth orbit change cycle, magma seepage disasters have occurred frequently in the dungeons of various continents.

I was walking home from school that day when the alarm went off when I heard the town hall announcement:

"All the citizens of F112 City should pay attention to the fact that the barrier in the north of the city has been damaged by in-situ stress, and magma has infiltrated! Magma has infiltrated! Now the magma flow has reached the fourth block! The exit of the highway has been blocked, and all the citizens have gathered in the central square and evacuated to the ground through lifting. Note that the evacuation should be carried out in accordance with Article 5 of the Emergency Law, and again, the evacuation should be carried out in accordance with Article 5 of the Emergency Law!"

I looked around at the labyrinthine passages around me, and the dungeon didn't look anything unusual right now. But I know the danger now: there are only two underground roads leading to the outside, one of which was blocked last year because of the need to reinforce the barrier, and if the remaining one is blocked, the only way to escape is to escape through the elevator that leads through the shaft to the surface.

The lifts are small enough to take a long time to get the city's 360,000 people out, but there's no need to fight for a chance to survive, and the coalition government's emergency law has everything in place.

In ancient times, there was an ethical question: when the flood came, should a man who could only save one person save his father or his son?

When I arrived at the central square, I saw a long queue of people by age. Closest to the elevator entrance are babies held by robot nurses, then kindergarten children, and then elementary school students...... I was at the top of the middle of the line. Dad is now on duty in low-earth orbit, and there are only me and my mother in the city, and I can't see my mother now, so I run along the long line, and I didn't go far before I was stopped by soldiers. I know she's in the last section, because the city is mainly a school center and there are few families, and she is already one of the older ones.

The long line moved forward at a heart-wrenching pace, and when it was my turn to step into the elevator three hours later, I didn't feel at all relaxed, because there were more than 20,000 college students between my mother and my survival......!

Two and a half hours after I reached the surface, the magma engulfed the city at a depth of 500 meters. I imagined my mother's final moments: she, along with the 18,000 people who had not been able to evacuate, watched the lava pour into the downtown square. The power was out, and the entire dungeon was covered only with the terrifying dark red glow of magma. The tall white dome of the square gradually darkened in the heat, and all the victims may have been killed by the thousands of degrees of heat before they even touched the magma.

But life goes on, and in this harsh and terrifying reality, love still flashes charming sparks from time to time. In order to ease the tensions, on the twelfth aphelion point, the coalition government actually resumed the Olympic Games after a two-century hiatus. I participated in the Olympics as a sled rally competitor in a sled that drove from Shanghai across the frozen Pacific Ocean across the ice to New York.

After the starting gun sounded, hundreds of sleds set off on the frozen ocean at a speed of about 200 kilometers per hour. At first, there were a few sleds with them, but after two days, they disappeared from the horizon, either in front of or behind.

At this time, the light of the earth engine behind me was no longer visible, and I was in the darkest part of the earth. In my eyes, the world is made up of a vast starry sky and an infinite ice sheet that stretches in all directions, and this ice sheet seems to stretch all the way to the end of the universe, or it is the end of the universe itself. And in the universe of infinite starry sky and infinite ice fields, I am alone! The avalanche of loneliness overwhelms me, and I want to cry. I hurried as hard as I could, the rankings no longer mattered, just to get rid of this terrible loneliness before it killed me, and the imaginary shore seemed to have no idea at all.

At that moment, I saw a figure appear in the sky. When I got closer, I saw a girl standing beside her sleigh, her long hair fluttering in the cold wind on the ice. You know what it means to meet a girl at this time, and the rest of our lives will be decided. She is Japanese and her name is Kayoko Yamabin. The women's group set off twelve hours ahead of us when her sleigh got stuck in a crack in the ice and broke a slide bar. I helped her fix the sleigh and told her how I felt.

"You're so right, I feel that way! yes, it's like you're the only one in the universe!

You know, when I see you from afar, it's like seeing the sun rise!"

"Then why didn't you call a rescue plane?"

"This is a race that embodies the human spirit, you know, the wandering earth can't be rescued in the universe!"

She waved her little fist and said with a persistence that is characteristic of the Japanese.

"But now we have to bark, we don't have a spare bar, your sled can't be repaired. ”

"Shall I take your sleigh with me, then? if you don't care about the rankings. ”

Of course I didn't care, so I walked the rest of the long way with Kayoko in the frozen Pacific Ocean.

After passing through Hawaii, we saw the light on the horizon. On the endless ice field, illuminated by that little sun, we sent a marriage application to the Ministry of Civil Affairs of the coalition government.

When we arrived in New York, the judges of the event had been waiting impatiently and had left. But there was an official from the Civil Affairs Bureau waiting for us, who congratulated us on our newlyweds and then began to fulfill his duties: he waved his hand to draw a holographic image in the air, on which tens of thousands of dots were neatly arranged, which is the number of marriages registered with the coalition government in the world in these days. Due to the harsh environment, the law stipulates that only one out of every three newlyweds has the right to have children, which is decided by lottery. Kayoko hesitated for a long time at the tens of thousands of dots in mid-air, and clicked on the middle one.

When that dot turned green, she jumped for joy. But I don't know what it feels like in my heart, is it lucky or unfortunate that my child was born in this time of misery? The official was so elated that he was very happy every time a couple "lit green", and he took out a bottle of vodka, and the three of us took turns drinking it one by one, and we all toasted to the continuation of mankind. Behind us, the distant sun gilded the Statue of Liberty with its faint glow, and across the horizon was the uninhabited skyscrapers of Manhattan, casting their shadows long and long on the silent ice of New York Harbor. I was drunk and hazy, and tears welled up in my eyes.

Earth, my wandering earth!

Before parting, the official handed us a bunch of keys and said drunkly: "This is the house you got in Asia, go home, oh, what a good home!"

"What's so good?" I said nonchalantly, "the dungeons of Asia are full of dangers, which you certainly don't experience in the Western Hemisphere. ”

"We're about to have a danger that you won't realize, and the Earth is going through the asteroid belt again, this time in the direction of the Western Hemisphere. ”

"The last few orbit cycles also passed through the asteroid belt, isn't it a big deal?"

"It's just grazing the edge of the asteroid belt, and of course the Space Fleet can handle it, and they can use lasers and nuclear bombs to remove all those little rocks from Earth's path. But this time...... You haven't watched the news? This time the Earth is going to pass through the middle of the asteroid belt! The fleet can only deal with the big rocks, alas, ......."

On the plane back to Asia, Kayoko asked me, "Are those rocks big?"

My dad is doing that job in the space fleet right now, so I know something despite the government's usual blockade of information to avoid panic. I told Kayoko that the rocks were as big as a mountain, and that a 50-million-ton thermonuclear bomb could only make a small hole in it. "They're about to use the most powerful weapon in human hands!"

I told Kayoko mysteriously.

"You mean antimatter bombs?"

"What else could it be?"

"What is the range of the space fleet?"

"Now they have limited power, my dad said only about 1.5 million kilometers. ”

"Ah, then we can see it!"

"It's better not to look. ”

Kayoko still watched it, and she didn't wear goggles. The first flash of the antimatter bomb came from space shortly after we took off, when Kayoko was admiring the stars in the sky outside the porthole of the plane, which blinded her eyes for more than an hour, and her eyes were red and swollen and tearful for more than a month. It was a heart-wrenching moment, as antimatter shells kept hitting asteroids, and annihilation flashes of bright light in the dark space, as if a group of giants in the universe were taking pictures with flashing lights around the Earth.

Half an hour later, we saw the fire meteors, which dragged their long tails of fire through the sky, giving people a terrifying beauty. There are more and more fire meteors, each of which streaks longer and longer in the air. Suddenly, the fuselage trembled with a loud bang, followed by a continuous loud bang and tremor. Kayoko screamed and threw herself into my arms, apparently thinking that the plane had been hit by a meteor, when the captain's voice rang out in the cabin.

"Please don't panic, this is a supersonic pop caused by a meteor breaking through the sound barrier, please wear headphones, otherwise your hearing will be permanently damaged. Since flight safety is no longer guaranteed, we will make an emergency landing in Hawaii. ”

Then I stared at a meteor, which was so much larger than the others that I didn't believe it could burn up in the atmosphere. Sure enough, the fireball sped across most of the sky, getting smaller and smaller, but it still fell into the sea of ice. From an altitude of 10,000 meters, a small white dot appeared at the place where the sea surface was hit, and the white dot immediately spread into a white circle, and the circle quickly expanded on the sea surface.

"Is that a wave?" Kayoko asked me in a trembling voice.

"It's a wave, a wave of hundreds of meters. However, the sea freezes, and the ice will quickly decay. I said to myself, soothing myself and not looking down again.

We landed in Honolulu soon and were arranged by the local government to go to the dungeon. Our car walked along the coast, the sky was full of fiery meteors, and the red-haired demons seemed to burst out at the same time from a point in space.

A meteor hit the surface of the sea not far from the coast, and no water column was seen, but a white mushroom cloud formed by water vapor rose high. The swell came from under the ice to the shore, and the thick ice rumbled and broke up, and the ice took on the shape of a wave, as if a group of soft beasts were swimming in a line below.

"How big is this one?" I asked the officer who had come to pick us up.

"No more than five kilograms, no bigger than your head. However, I just received a notice that on the sea surface of 800 kilometers to the north, a 20-ton one had just fallen. ”

At this time, the communication machine on his wrist rang, he glanced at it and said to the driver: "It's too late to get to Gate 204, let's find an entrance nearby!"

The car turned a corner and stopped in front of an entrance to a dungeon. When we got out of the car, we saw several soldiers at the entrance, all of them staring motionlessly in one direction in the distance, their eyes full of fear. We all followed their gaze, at the line between the sky and the sea, we saw a black barrier, at first glance it seemed to be a low cloud on the horizon, but the height of the "cloud" was too uniform, like a long wall across the sky, and then look closely, the wall is still inlaid with a line of white edges.

"What's that?" Kayoko timidly asked an officer, and the answer she received made our hair stand on end.

"Waves. ”

The tall iron gates of the dungeon rumbled shut, and after about ten minutes we felt a muffled sound coming from the ground, gurgling, like a giant rolling on the ground. We looked at each other, and we all knew that the 100-meter-high wave was rolling through Hawaii and would roll across all continents. But another kind of vibration is even more terrifying, as if there is a giant fist constantly hitting the earth from space, in the underground this vibration is not large, can only be vaguely felt, but each vibration goes straight to the depths of our souls. It's a meteor that's constantly hitting the ground.

The brutal bombardment of our planet continued intermittently for a week.

As we walked out of the dungeon, Kayoko exclaimed, "Oh my God, how is this the case!"

The sky is gray because the upper atmosphere is filled with dust from asteroids hitting land, and the stars and the sun disappear into this endless gray, as if the whole universe is under a fog. On the ground, the sea water left behind by the huge waves froze before it could recede, and the surviving high-rise buildings of the city stood alone on the ice, hanging long ice cubes. A layer of impact dust fell on the ice, and the world was left with only one color: gray.

Kayoko and I continued our trip back to Asia. As the plane crossed the already meaningless International Date Line, we saw the darkest night ever seen. The plane seemed to be sneaking in a sea of ink, and looking at the world outside the cabin without a trace of light, our mood was also extremely gloomy.

"When will it end?" Kayoko murmured. I don't know if she was referring to this journey or this life of suffering and disaster, I now feel like there is no end to either. Yes, what if the earth sailed out of the helium flash circle and we were able to escape? We were only at the bottom of the long ladder, and our bones would be turned to ashes when our hundred great-grandchildren climbed to the top of the ladder and saw the light of new life. I don't dare to imagine the hardships and hardships in the future, let alone the muddy road with my lover and children in sight, I am so tired that I can't walk anymore...... Just as I was suffocating with grief and despair, a woman's exclamation rang out from the cabin: "Ahhh

I followed the sound and saw that the woman was snatching a pistol from a man next to me, who had apparently tried to bring the muzzle of the gun to his temple. The man was thin and stared blankly at the infinite distance ahead. The woman buried her head in his lap and began to weep.

"Quiet. The man said coldly.

The crying was gone, only the hum of the plane's engine was soft, like an unchanging mournful music. It was in my sense that the plane had stuck to this great darkness, motionless, and the whole universe, except the darkness and the plane, was nothing. Kayoko was clung to my arms, cold all over.

Suddenly, there was a commotion at the front of the cabin, and someone was whispering excitedly. I looked out the window and saw a hazy light in front of the plane, blue and shapeless, very evenly seen in the night sky in front of me that was filled with crashing dust.

That's the glow of the Earth's engine.

A third of the Earth engines in the Western Hemisphere had been destroyed by meteorites, but the damage was less than predicted before the voyage began; In terms of power, they are capable of escaping the Earth.

In my eyes, the hazy blue light in front of me was like the bright light of the sea after a long ascent from the deep sea, and my breathing became easier again.

I heard the woman's voice again: "Honey, pain and fear are things that can only be felt when you are alive. Dead, dead and nothing, there is only darkness over there, it is better to be alive. What do you say?"

The emaciated man didn't answer, he stared at the blue light in front of him, tears streaming down his face. I knew he could live, and as long as the blue light of hope was on, we could all live, and I remembered my father's words about hope.

As soon as we got off the plane, Kayoko and I didn't go to our new home in the dungeon, but instead went to the space fleet base on the ground to look for my father, but at the base, I only saw a cold medal posthumously awarded to him. The medal was given to me by an Air Force Major General, who told me that during an operation to clear the Earth's path of asteroids, an asteroid fragment blasted by an antimatter bomb hit my father's single-seat miniature spacecraft.

"The relative velocity of the stone and the ship was 100 kilometers per second, and the impact vaporized the cockpit of the ship instantly, and he did not suffer at all, I assure you, not at all. The general said.

When the earth was falling back into the sun, Kayoko and I went to the ground again to see the spring, but we didn't see it.

The world was still gray, and under the gloomy sky, there were frozen lakes formed by the remnants of seawater, and there was not a trace of green to be seen. Impact dust in the atmosphere blocks sunlight and makes it difficult for temperatures to rise. Even at perihelion, the sea and the earth did not thaw, and the sun took on a hazy halo, as if it were a ghost behind the crashing dust.

It was three years before the impact dust in the sky dissipated, and humanity finally passed perihelion for the last time, rising towards aphelion. At this perihelion, people in the Eastern Hemisphere had the privilege of witnessing one of the fastest sunrises and sunsets in Earth's history. The sun rises above the sea level and quickly crosses the sky, and the shadows of everything on the earth quickly change angles, as if they are the second hands of countless clocks. It's also the shortest day on Earth, with less than an hour.

When the sun sank to the horizon an hour later and darkness fell on the earth, I felt a pang of sadness. This fleeting day seems to be a brief summary of the 4.5 billion years of Earth's evolutionary history in the solar system. Until the end of the universe, it will not return.

"It's dark. Kayoko said sadly.

"The longest night. I said. This night in the Eastern Hemisphere will last for 2,500 years, and it will be a hundred generations before the dawn of Centauri will once again illuminate the continent. The Western Hemisphere will also face the longest days, but much shorter than the nights here. There, the Sun will soon rise to the zenith, and then remain at that point and gradually diminish until within half a century, it will merge into the constellation and become indistinguishable.

Following its predetermined course, the Earth ascends to the conjunction with Jupiter. The plan of the Navigation Committee was that the orbit of the Earth's 15th circle would be so flat that its aphelion would reach Jupiter's orbit, and the Earth would pass by Jupiter at a distance of almost collision, and the Earth would eventually reach escape velocity under the pull of Jupiter's enormous gravitational pull.

Two months after leaving perihelion, Jupiter was visible to the naked eye, and it started as a faint point of light, but soon took on the shape of a disk, and after another month, Jupiter was the size of a full moon above the Earth, dark red, and the streaks on it could be faintly seen. At this time, some of the pillars of light of the Earth's engine, which had been vertical for 15 years, began to swing, and the Earth made its final attitude adjustment before the rendezvous. Jupiter gradually sank below the horizon, and for more than three months, Jupiter was on the other side of the Earth, and we could not see it, but we knew that the two planets were in the process of meeting.

One day we were suddenly told that Jupiter could be seen in the Eastern Hemisphere, and people rushed from the dungeons to the surface. When I stepped out of the city's sealed doors and onto the surface, I found that the Earth's engines that had been on for 15 years had all been turned off, and I saw the stars again, indicating that the final rendezvous with Jupiter was underway. People were staring nervously at the western horizon, and a dark red light appeared on the horizon, and the area of light gradually expanded, extending to the entire width of the horizon. I now found that there was a neat boundary between the dark red area and the dark starry sky, and the boundary was in an arc, and the huge arc crossed from one end of the horizon to the other, and slowly rising, and the sky under the huge arc turned dark red, as if a dark red curtain the size of the starry sky was separating the earth from the whole universe. When I came back to my senses, I couldn't help but gasp, the dark red curtain was Jupiter! I had known for a long time that Jupiter was 1,300 times the size of the Earth, and now I really felt its enormity. The sense of dread and depression that the cosmic troll felt as it rose over the horizon is difficult to describe in words, as one journalist later wrote:

"I don't know if I'm in a nightmare, or if this entire universe is a nightmare in the Creator's huge, perverted mind!" Jupiter rose in terror, gradually taking over half of the sky. At this point, we could clearly see the storm in its clouds, which churned the clouds into confusing chaotic lines, and I knew that beneath the thick clouds was a boiling ocean of liquid hydrogen and liquid helium. The famous Great Red Spot appeared, a great vortex that had sustained Jupiter's surface for hundreds of thousands of years, so large that it could swallow three entire Earths. At this time, Jupiter has occupied the whole sky, and the earth seems to be a balloon floating in the sea of dark red clouds boiling with Jupiter! And Jupiter's great red spot is right in the middle of the sky, like a giant red eye staring at our world, and the earth is shrouded in its eerie red light...... At this time, no one can believe that the small earth can escape the gravitational field of this huge monster, from the ground, the earth can not even become a satellite of Jupiter, we are about to fall into the hell covered by the boundless sea of clouds! But the calculations of the pilot engineers are accurate, the dark red confused sky is slowly moving, I don't know how long it took, the western horizon revealed a black corner, the black is rapidly expanding, there are stars twinkling in it, the earth is rushing out of Jupiter's gravitational clutches. At this time, the alarm screamed, and the gravitational tide generated by Jupiter was advancing inland, and it was later learned that this time the tide was more than 100 meters high and the wave once again swept the entire continent. As I ran into the sealed door of the dungeon, I took one last look at Jupiter, which still occupied half of the sky, and found a clear scratch in Jupiter's sea of clouds, which I later learned was the trace of the Earth's gravity on the surface of Jupiter, and our planet also pulled up huge waves of liquid hydrogen and liquid helium on the surface of Jupiter. At this time, Jupiter's huge gravitational pull is accelerating the Earth into outer space.

By the time it left Jupiter, the Earth had reached its escape velocity, and it no longer needed to return to the sun where death lurked, and flew into the desert of outer space, and the long era of wandering began.

It was in the dark red shadow of Jupiter that my son was born deep in the earth's strata.
