The screen changed again. At this time, everyone was inside the space battleship Feijin, in a circular corridor.

Tianpeng and others were very surprised. They had been looking at the battleship outside before, but when they got inside, they realized how huge the battleship was inside and how small they were.

"How many people can this battleship accommodate?"

"Under normal circumstances, it can accommodate a population of 2 million, but the number of humans in Feijin has exceeded 3 million. Now let alone lack of energy, even food is scarce. Humans will not be able to survive for half a month."

Tianpeng and others saw a dense crowd of people standing under the circular corridor. They were arguing, as if the riot was caused by unfair food distribution.

The elder waved his hand again, and the screen jumped to the cabin of the time machine.

There is a huge time machine parked in this large cabin, which is estimated to be able to transport thousands of people each time it is run.

The elder explained: "This time machine took about 200 years to develop and went through numerous scientific research teams. Finally, Dr. Lin completed the final stage."

Tianpeng saw countless people walking into the time machine, and they also brought many personal belongings with them.

"To what time can this time machine be transported?" Jiang Hao asked curiously.

"If you use the time on your current surface as a standard, it would be 220,000 years ago. At that time, the earth had the most perfect environment, and early Homo sapiens, the primitive humans, had already appeared."

The elder waved his hand again. This time the picture was of the earth 220,000 years ago.

A total of more than 3 million human beings came to the earth successfully. They forgot all the sorrow and pain, cheered and celebrated crazily...

In this way, Lin Hope and Exmila became heroes of mankind, and mankind even erected two statues for them. However, the happy days did not last long, and mankind only lived peacefully on the earth for about 200 days. Once again,

Bad news comes.

"The detector has detected that a super comet is heading toward the Earth. With this collision, life on Earth is likely to be exterminated. The impact time is 30 days later, and human beings are running out of time."

"How could a comet hit the earth 220,000 years ago?" Jiang Hao asked in surprise.

"Have you ever heard of the butterfly effect? ​​In the original timeline, everything was set up. But the sudden arrival of more than 3 million people broke the original settings, destroyed the original timeline, and infinitely amplified the butterfly effect. Human beings

Not only has it greatly affected the development of the earth, but it has also affected the development of other planets in the universe. The super comet originally would not have hit the earth, but would have passed by it, but now it has hit the earth."

"What happens after that? How do humans get through this?"

"Human beings were too greedy when they traveled through time and brought too many things from the future. Maybe it was these things from the future that caused the comet to hit the earth, but it was also these things that saved mankind."

"I understand, in order to survive, human beings began to dig into the ground and kept digging underground." Tianpeng guessed.

"It's easy for you to say it, but it's hard to do it. Although humans at that time had highly developed technology and powerful tools, it was not that easy to create an underground world." The elder waved his hand again and turned the screen.

.

At this time, Tianpeng and others found themselves in a mine, with countless people working and digging underground.

With 20 days left before the impact, humans have already dug more than 5,000 meters underground, and began to expand the space crazily at more than 5,000 meters. The rocks brought up from the underground are piled on the land, like a large mountain range.

In order to survive, human beings are racing against time to transform the underground, transporting various soils, plants, and domestic animals from the surface, and finding ways to energize the underground to ventilate and purify the air in the underground world, and then connect underground water facilities to create facilities.

Facilities that can carry out small-scale artificial rainfall.

With one day left before the impact, the first underground world was formed.

In this initial underground world, the space here is very large. Various simple houses and facilities have been built. Those high-tech tools are very terrifying and have given mankind great convenience. Without those high-tech tools, the underground world would not be possible.

It can be done.

After that, the comet came to the earth as promised.

With a loud bang, the only passage connecting the surface to the underground world was buried. At this point, the underground world and the surface world were isolated.

The screen disappeared and the entire room turned white again.

The elder led everyone out of the room, but everyone's hearts still couldn't calm down for a long time. They always felt that something was missing.

"Elder, you haven't said anything about what happened next?" Tianpeng asked.

"What happened next? Human beings have settled in the underground world, and they don't know what's going on on the surface."

"Why don't humans in the underground world go to the surface? It should be okay to rely on those tools, right?" Jiang Hao asked.

"Because of fear! Human beings in the underground world are forbidden to go to the surface, and all underground people begin to believe in theology."

"theology?"

"It means believing that there is a God in the world, and that everything is a punishment from God to mankind. Humanity must atone for its sins and will never be allowed to return to the surface again. However, these are also theories created by rulers to facilitate their rule. In fact, the official explanation is

:In order to reduce the butterfly effect, humans should no longer interfere with the world on the surface.”

"What about primitive humans? Those early Homo sapiens." Tianpeng asked.

"Although Homo sapiens are also human beings, they are very different from us. Therefore, humans did not bring all Homo sapiens with them at that time. They only brought some of them. At first, those Homo sapiens were mainly used for research, but later those Homo sapiens were used for research.

Human intelligence has been well developed and gradually integrated into human beings."

"I am referring to the Homo sapiens on the surface." Tianpeng emphasized.

"Needless to say about the Homo sapiens on the surface, they survived, lived through the end of the world, and then continued to multiply. Your ancestors are those Homo sapiens on the surface who survived."

"Have the underground people never thought about returning to the surface? Isn't this abnormal? It's been more than 200,000 years, and they have never thought about it? Absolutely impossible." Jiang Hao asked.

"Come with me to another holographic room. That room records the history of the underground people."

Everyone followed the elder to another room. After closing the door, the room switched to a highly developed underground world.

The current underground world is no longer the original underground world. There are houses, high-rise buildings, robots, aircraft and other things that represent a high degree of civilization. The streets are full of people, and everyone seems to have arrived in a metropolis.

"Is this a festival? Why are there so many people?" Li Ming asked.

"No, it's just that there are too many people. After all, the underground world is not as big as the land world. The growing population has quickly become the biggest problem for mankind. In just over 100 years, the population of a small underground world has reached more than 100 million.

"

I’m busy today, so I’ll do a small update, and I’ll do a big update tomorrow, and I’d also like to thank the new tippers.
Chapter completed!
