After rushing back from the northern border, taking advantage of the sudden cold weather in the south of the Yangtze River, Lu Tong and the others started decorating their new house again.

When they left more than three months ago, the house had been built. In order to allow Qiu Siyuan and the others to adapt to the life style of humans on Earth and to take into account the characteristics of their living environment in Kuiper's old human space city, Cui Jianfeng tried his best to make the house as bright as possible.

Sufficient and spacious.

Because Lu Dazhu's murder case has been canceled by Zheng County Magistrate, and the case of dehumanizing a god and committing rebellion has been going on for a long time, but nothing was found. As people like Lu Hechang, Gao Zhao, and Zheng Mingjie began to investigate the so-called dehumanizing of gods,

As their awareness of the incident increased, they all lost interest in the so-called debasement and were too lazy to ask any more questions.

Soon, Qiu Siyuan took Liang Haiming, Sun Xiaogang and others from the Chunlai Inn in front of the county government to live in the house prepared for them by Cui Jianfeng and others. In order not to attract the attention of the villagers, Qiu Siyuan and others did not use the money they brought after moving in.

Instead of generating electricity for lighting equipment, they use vegetable oil lamps for lighting like the villagers. That is, put vegetable oil in a plate on the lamp stand, put a lamp made of cotton on the edge of the plate, and light it with a flint.

The villagers only knew that a group of people had moved here from the county town, but they did not know that these movers were actually the astronauts that the village had been talking about before.

Cui Jianfeng also worked with County Magistrate Gao to provide Qiu Siyuan and others with three household registration files of Datang residents transferred from Shengtang County to Wucheng County. Based on these certificates, Cui Jianyong gave Qiu Siyuan and others a portion of land in Liuhe Village for their farming purposes.

After that, Qiu Siyuan rarely left the village. Just like the farmers in the village, he began to learn farming skills, tried his best to communicate with the farmers, and wanted to integrate into the new round of earth civilization as soon as possible. Of course, as the person in charge of communication with humans on earth,

As a member of the Kuiper Space Expedition, he sometimes has to go back to his space city in the Kuiper Belt. Once he goes there, it takes more than ten days to go back and forth.

After Lu Tong and Qiu Siyuan in Liuhe Village went sightseeing in the Kuiper Belt and the outer shell of the solar system, they realized that the world around them was not like the folklore, where there was heaven and the Jade Emperor, but there were people living like themselves.

Planets in space or man-made space cities. In this way, he also became very interested in Qiu Siyuan's life history. He often asked Qiu Siyuan to talk about his life experiences during the last round of earth civilization.

Because Lu Tong often mentioned his experiences in the last round of earth civilization, Qiu Siyuan often fell into deep thought, recalling his time in the prehistoric civilization period that would never return, and recalling his unbearable experience in that apocalyptic disaster.

During the last round of earth civilization 700 million years ago, Qiu Siyuan was a physics teacher in a school in a coastal city at the southern end of the continent called Laurasia. This city was called Laurasia.

Linyang City is the largest city in Asia.

The level of human civilization at that time was much higher than today. Human beings had entered space and built cities and settled in space. However, the living materials in the space cities still relied on the earth. Although humans at that time also conducted breeding experiments in space and also produced products.

All green foods cannot survive independently from the earth. This is because the materials that maintain normal human life, such as food, cannot be synthesized independently of the earth's biological and food chains. Although green foods produced in space can

Normal consumption, but through biological research, humans have discovered that green food produced in space cannot guarantee all the substances necessary for human life activities, because many essential substances for human life activities are missing in these products. If consumed for a long time, humans will also

Life is weakened and goes extinct. For this reason, although relevant scholars have carried out research and want to improve the food structure produced by growing in space, it has unexpectedly happened that naturally produced green food on the earth cannot be copied. That is,

It is said that without leaving the earth, it is difficult for humans to live for a long time on food produced in space. The main reason is that the ingredients in this food are different from the food produced in the biological chain in nature on earth. Many important ingredients are missing, so it is not supported.

necessary conditions for the long-term survival of human beings.

However, an unexpected catastrophe unexpectedly changed the peaceful life of the last round of earth civilization, causing the last round of earth civilization to play its tragic ending song.

That was caused by the crash of the innermost planet in the solar system at that time, that is, it hit the sun.

Just because of the collision of this planet with the sun, the orbits of the inner planets were retracted. Venus was retracted to near the orbit of the inner planet that crashed into the sun, and the earth was retracted to near the orbit of Venus. This means that the earth is separated from its original position.

The solar system is the only orbit suitable for the emergence of life. In this way, the last round of human beings on earth has entered the countdown to life.

And what about Mars? Mars has shrunk in close to the orbit of the Earth, which is the only orbit in the solar system suitable for biological activities. This also provides an opportunity for the birth of Martians.

In this case, three completely different options appear in front of the people on earth, namely:

The Earth School: advocates that humans move underground, build underground residences, and move farming underground to create a self-sufficient underground living environment.

Iskra School: Emphasizes that humans move to Mars, transform the atmosphere and soil of Mars, and continue to live the same life as on Earth. This is the prototype of the Martians.

Space School: advocates going into space and using spaceships or space cities to survive in the space between Jupiter and the Earth. Some of them propose flying into deep space and living on terrestrial planets outside the solar system.

The three factions competed fiercely for personnel, divided resources, and implemented their own projects, making people living in the shadow of the doomsday increasingly nervous. People also supported the faction that believed to be correct according to their own opinions.

, thinking that when a disaster strikes, I can find a safe place to continue living.

The planet that was about to hit the sun was named Gen at the time. Space scientists had long predicted based on its orbital parameters that it would hit the sun in a few decades. They also predicted that its crash would bring consequences to humans on Earth.

A devastating disaster. The main reason is that if the inner planet crashes, it will affect the original layout of the inner planet and cause the orbit of the inner planet to shrink inward. This means that the earth will be separated from its original environment, the only place in the solar system suitable for biological derivation.

Orbit. In that case, because the Earth's orbit shrinks to near the orbit of Venus, it will become unbearably hot, the ground will be scorched, vegetation and houses will be burned, and the atmosphere will become as turbid as Venus, and humans will no longer be able to survive.

This planet is difficult to observe because it is closer to the sun. Qiu Siyuan is a physics teacher and sometimes leads his students to observe various celestial objects using telescopes. Gen Star is also a celestial body that attracts their attention.

Because human civilization in the last round of earth civilization was higher than today, humans at that time had entered space and even built structures on Sanlun (the satellite of the earth at that time), Mars and Galaxy (the parent body of the asteroid belt).

Space Palace. This means that most people agree to go into space or move to Mars.

However, there are still some people who are obsessed with life on earth, so there are also many people who turn to underground life.

"Did you often travel to the moon at that time?" Lu Tong was fascinated by the stories told by Qiu Siyuan, and asked about it from time to time.

"The moon that orbited the earth back then was not the moon now, but another earth satellite, which is the third wheel I just talked about."

"Three wheels?" Lu Tong looked at Qiu Siyuan strangely, feeling incredible: "Isn't it the current moon?"

"Yes."

"Where is the third round now?" Lu Tong asked curiously.

"I'm not sure. Anyway, when I first came to Earth after being resurrected by the Kuipers, I felt that the current moon was different from the thirty-year-old moon I saw back then."

"What's the difference?"

"The moon I saw back then was red in color, but the moon now is silvery white, and it seems to be much smaller than the moon we had back then."

"What's going on? Is the moon shrinking too?"

"How do I know? I had been dead for more than five thousand years at that time. However, I heard from the Kuiper Fire Source astronauts that the 3rd wheel was shattered when it hit the Milky Way, and its remains are today's asteroid belt."

"Oh," Lu Tong's eyes widened in surprise: "According to you, there was a planet called Silver Star before?"

"Yes, its size is slightly larger than the earth." Qiu Siyuan's eyes flashed with tears: "Unfortunately, now I can no longer see it."

"Then have you been to Silver Star?"

"Yes," Qiu Siyuan said with a painful expression and tears in his eyes: "At that time, during holidays, I would take my parents, wife, and children with me to travel to the Galaxy in our own space shuttle. Later, my parents passed away.

We were also told before that when they passed away, their bodies would be transported to the Silver Star for burial. Who would have expected that."

"So there are your parents' graves on Silver Star?" Lu Tong asked again with his eyes wide open in disbelief.

"Yes." Qiu Siyuan burst into tears and sobbed: "After I was woken up by the Kuipers, the first thing I wanted to see was the Silver Star visiting my parents' cemetery. But who would have expected that my Silver Star would

It has become a gravel belt.”

"So, it's been a very long time since your death. It's so long that we can't believe it."
