The geological features of the planets selected by human scientists are pretty good. Basically, there will be no accidents such as earthquakes and volcanic eruptions, and no unknown microorganisms have been detected.

However, due to its geographical location in the outer space of the planetary system, rare earth elements may be relatively small.

In order to reduce the possibility of being discovered by the human branch of "bright galaxy", human beings can only choose such a very peripheral planet, and the initial industrial development may be difficult.

Fortunately, in the process of developing planetary engines, human beings have mastered the technology of mining deep crustal resources. As long as it takes some time, the problem of lack of rare earth minerals should be solved.

The first engineers of the past have started excavators to excavate underground cities They are the most hardworking people, working in the dark environment, even the high brightness of the nuclear fusion lamp also dare not light.

According to the photos, another human Mothership, bright galaxy, is moving slowly in the synchronous orbit of the third planet, with a long space elevator below.

It seems that there is a good development of human beings over there.

However, human beings on both sides have been separated for more than 400 years. Anything can happen in such a long time. It's even harder to integrate directly.

Therefore, human beings in Kunlun Mountain do not place their own safety on other people, even though they may be ready for refuge Still can't trust each other completely.

Just in the past, the new human civilization with a large number of people in hibernation is the most vulnerable time, and relying on oneself is the safest behavior. So secretly landed on a peripheral planet, God knows it or not, so slowly developed.

After the general's report, another diplomat came to power to report on the progress of contacts with the tosian civilization.

Humans chose the star 1 light-year away, while the tosian civilization chose a red dwarf 1.2 light-year away. The distance between the two stars is very close, about 0.5 light-year.

The two sides did not stay together. Even though the two civilizations have formed a deep friendship, it is a wise choice to separate them in this most vulnerable period when most of the machinery and equipment are abandoned.

Well, this is also a defense, that is also a defense. It sounds like a mouse, but it's impossible.

"We plan to restart communication between the two sides in 10 years. We have signed a large number of cooperation treaties with Toshi civilization, including science and technology mutual benefit agreement, data exchange agreement and so on. "

"If we really have curvature technology, I believe that in the future, we will meet again."

Zhang Yuan nodded, this plan is very safe, there is no problem.

Next, there are various details about the relocation of all human beings. Although such details have been discussed many times, at this moment, with the first-hand geological data, we need to discuss them according to local conditions.

Ye Kaifu, an engineer, raised his hand and said, "I'm not sure The density of the planet is low and geological activities are not frequent. It's not complicated to build a shelter. It's OK to dig one by yourself in a few years. I think three or five years will be enough! "

"So the second group of people who land must be a large number of Engineers The required machine models are A235, a421 The model of deep crust drill is.... "

After the whole program passed quickly, the second batch of people entered the flying saucer.

In the second batch of transportation, half of the space is still mechanical tools, and the other half is loaded with about two million engineers, all of whom are in hibernation. These flying saucer systems are not good enough to support millions of people living in them, so most people have to hibernate.

In addition, there are about 50000 sober people. These are doctors and nurses responsible for awakening.

Zhang Yuan's wife, Lin Xuanxuan, also left in the second group.

They don't need to hibernate.

Engineers have to quickly build their own shelters on that alien planet, while doctors and nurses are responsible for waking up the hibernating population.

There is not much room for progress in hibernation technology. It is impossible to work as soon as you wake up from hibernation. No matter how long you have to rest for a week.

The third batch was ordinary people and a small amount of equipment.

After saying goodbye to the Kunlun Mountain carrier and the underground city, these people all happily lay in the hibernation warehouse, and a large number of hibernation warehouses were pulled into the flying saucer by some large high-speed trains.

In order to move faster, people built 40 million hibernation barns in the past few years. Everyone was assigned one. After arriving at the target location, the train drove out again and into the underground base to unload the hibernation warehouse. Then these trains will become industrial trains, carrying minerals back and forth.

As for the hibernating population, they will wait in line to wake up.

There are so many people in need of thawing that doctors can't take care of them at all. In addition, the underground shelters haven't been built so quickly. Before it is completely built, its ability to survive is not strong.So the whole process of thawing will be gradual, which may last about ten years.

These related matters have been informed in advance, and everyone knows it.

Time passed quickly, flying saucers went back and forth for another three months, and then the fourth batch, the fifth batch, the Sixth Batch

Zhang Yuan and other cadres left in the last batch. By this time, the vast majority of the population had been evacuated, and pangunao had been reloaded onto a flying saucer and carried over.

The new human civilization also bid farewell to the high level of Toth civilization.

The two sides have been together for 1500 years. Although there is a little contradiction between them, they have finally achieved their big goal.

Really It's not easy!

Even if people don't get curvature technology in the end, the friendship between the two sides will last forever and will continue.

"Good luck to us! Good luck to you, too

The individual life span of the tosian civilization is longer, but their leadership has changed for such a long time.

The supreme leader is no longer the former giant salamander, but a smaller one with his two tentacles swaying.

The captain said, "I hope we will have curvature technology when we meet again later We will be able to cooperate further then! "

"Of course, we also want to have a pair of real eyes! We'll cooperate then! "

The simple separation ceremony soon ended, and a lot of machinery and equipment were abandoned here, including the underground city where they used to stay, and gradually stopped running.

Zhang Yuan sees that a long stagnant Planetary Fortress outside the window, re ejecting colorful ion flames. The artificial intelligence carefully prepared by both sides has started the final stage of work.

Looking up, you can see that the Kunlun Mountain, which has been with human beings for a long time, quietly stays in the upper space of the big ice hockey.

This Mothership is too big to move away, but it will stay here to witness the collision of neutron stars.

People are going to abandon this Mothership for thousands of years. From glitzer 581 to here, she completed her mission.

The engineers set up the relevant program very well. When the neutron star really collides, it should hide behind the big ice hockey, and then send a series of pulse data in the direction of human beings

"I still remember starting from glitzer 581, Kunlun Mountain was brand new. It was very high spirited at that time. " Li Zhendong, sitting next to him, sighed.

"Maybe, hiding behind the big hockey, she will survive Millions of years later, what about being picked up by other civilizations? "

"Goodbye, Kunlun mountain!"

"Goodbye!"

A lot of people are saying goodbye to this former mothership.

Zhang Yuan sighed in his heart and got into the hibernation warehouse

Goodbye, Kunlun mountain!
