The planets selected by human scientists have a decent geological appearance, with 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 the "Bright Galaxy", human beings can only choose this kind of very peripheral planet, and the initial industrial development may be more difficult.

Fortunately, in the process of developing planetary engines, mankind has mastered the technology of exploiting resources deep into the earth's crust, and the problem of lack of rare earth minerals should be solved with some time.

The first engineers of the past have turned on excavators to excavate underground cities...... They are the hardest working people, working in the dark, and they don't even dare to light the high-brightness fusion lamp.

The photos show that the other human mothership, the Brilliant Galaxy, is moving slowly in the synchronous orbit of the third planet, and a long space elevator appears below.

It seems that the human race over there is doing well.

It's just that the humans on both sides have been separated for more than 400 years. With such a long period of time, anything can happen. It's hard to fit right in.

Therefore, the humans of this branch of Kunlun Mountain will not completely pin their own safety problems on others, even if the other party is likely to have prepared a shelter...... I still can't fully trust each other.

The new human civilization, which has just passed and is hibernating, is the most vulnerable, and relying on oneself is the safest behavior. Just sneakily landed on an outer planet, unknowingly, and it was good to develop it slowly.

After the general's debriefing, another diplomat came to the stage to report on the progress of contacts with the Toth civilization.

Humans chose the star 1 light-year away, while the Toth civilization chose a red dwarf star at 1.2 light-years, and the two stars are very close together, about 0.5 light-years.

The two sides did not continue to stay together. Even if the two civilizations have forged a relatively deep friendship, it is wise to separate from each other at this time when most of the fragility is the time 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 is timid, but this is also a thing that can't be helped.

"We intend to restart communication in 10 years' time. We have signed a large number of cooperation treaties with the Toth civilization, including scientific and technological reciprocal agreements, data exchange agreements, and so on. ”

"If there is really curvature technology, I believe that in the future, everyone will still have a time to meet."

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

Then there are the details of the relocation of all mankind, which have been discussed many times, but at this moment, with first-hand geological information, they need to be discussed in accordance with local conditions.

Engineer Ye Kaifu raised his hand and said, "...... The density of the planet is on the low side, and geological activity is infrequent. It's not complicated to set up a shelter, it takes a few years to dig one yourself, I think three or five years is enough! ”

"So the second batch of people who landed must be a large number of engineers...... The required machine models are A235, A421...... The model of the deep crust drilling rig is ......"

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

Half of the second shipment was still made up of mechanical tools, and the other half was loaded with about two million engineers, all of whom were in hibernation. These UFO systems are not very good, and it is difficult to carry millions of people living in them, so most people have to hibernate.

There are also about 50,000 awake people, and these are the doctors and nurses who are responsible for reviving.

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

They don't need to hibernate.

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

There is not much room for progress in the technique of hibernation, and it is impossible to be able to work vigorously as soon as you wake up from hibernation, and you have to rest for a week.

The third batch is the general population and a small amount of equipment.

After saying goodbye to the Kunlun Mountain Mothership and the underground city, these people all lay down in hibernation chambers in high spirits, and some large high-speed trains pulled a large number of hibernation chambers into the flying saucers.

In order to move more quickly, people have made 40 million hibernation chambers in the past few years. Each person is assigned one, and upon reaching the target location, the train re-exits and enters the underground base to unload the hibernation chamber. These trains will then become industrial trains, carrying minerals back and forth.

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

With so many people in need of thawing, the doctors simply can't take care of them, plus the underground shelters haven't been built so quickly. Until it is fully built, it is not very capable of sustaining life.

So the whole thawing process will be gradual, probably lasting about ten years.

These relevant matters have been informed in advance, and everyone knows it in their hearts.

Time passed quickly, and the flying saucer went back and forth, another three months, and then the fourth, fifth, and sixth batches......

Zhang Yuan and other cadres were the last to leave. At this time, the vast majority of the population had been evacuated, and Pangu Brain had been reloaded onto flying saucers and carried over.

The new human civilization also said goodbye to the upper echelons of the Toth civilization.

The two sides got along for 1,500 years, and although there were a little contradictions in the middle, they finally achieved their big goals.

It's true...... It's not easy!

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

"Good luck to us! Good luck to you guys too! ”

The individuals of the Toth civilization lived longer, but for such a long time, their leadership team has also changed.

The Supreme Leader is no longer the big baby fish he used to be, but a smaller one, and his two tentacles are dangling.

The captain said, "I hope that when we meet again in the future, we will already have curvature technology...... We will be able to cooperate further when the time comes! ”

"Of course, we also want to have real eyes! Let's work together when the time comes! ”

The simple separation ceremony was soon over, and a large number of mechanical equipment was abandoned here, including the underground city where it had been staying, and gradually ceased to function.

Zhang Yuan saw that outside the window, the planetary fortress that had been stagnant for a long time was re-spewing out colorful ion flames, and the artificial intelligence carefully prepared by both sides began the final stage of work.

Looking up, you can see that the "Kunlun Mountain", which has been with mankind for a long time, is quietly staying in the upper space of this big ice hockey ball.

This mothership is too big to be moved all together, but will stay here and witness the collision of neutron stars.

People are about to abandon this thousand-year-old mothership. From Gliese 581 to here, she has fulfilled her mission.

The engineers were very kind to program that when the neutron stars actually collided, it would hide behind the big ice ball and send a series of pulses in the direction of humans......

"I still remember that when we set off from Gliese 581, the Kunlun Mountain was still brand new. It was really high-spirited at that time. Li Zhendong, who was sitting next to him, sighed.

"Maybe she'll survive hiding behind the big puck...... Millions of years later, what about being picked up by other civilizations? ”

"Goodbye, Kunlun Mountain!"

"Goodbye!"

Many are saying goodbye to the former mothership.

Zhang Yuan sighed in his heart and went into the hibernation warehouse......

Goodbye, Kunlun Mountain!
