Inside the Earth Age, the plant culture area "Aruba" grows luxuriantly. The living area is well lit and the rooms are tidy.

Most of the pangolins were sleeping soundly, and a small number of them jumped out and greeted them respectfully when they saw the humans, and this gratitude came from the bottom of their hearts.

For Zhang Yuan, the older he grows, the more difficult it is to be happy from the heart, and the more he experiences, the higher the threshold of happiness will be, and this time, Zhang Yuan can't help but be happy.

Not only Zhang Yuan, but almost all human beings have produced an indescribable happiness.

Obsession is beautiful, and immaturity is also beautiful. Perhaps human mathematics is still lacking to a great extent, or perhaps, no matter how advanced mathematics is, it is impossible to calculate everything......

Zhang Yuan casually looked at it, their living space is very small, about 1 square meter per person. Like humans, the living space needs at least 10 square meters, but the Gliese people only need 1 square meter, so it is not cramped with 3 million people.

And this small living space is also very comfortable for them, and the satisfaction is very high.

After a general round, the group returned to the Starry Sky Harbor.

The air pressure gate closed slowly, and Zhang Yuan couldn't help but feel a sense of nostalgia from the bottom of his heart......

This should be the last time they will log in to the Earth Age. Once you leave, you will never be able to return to this spaceship in your lifetime.

Man is always a creature that misses the past, more than 3,000 years ago, the starting point of all stories began with this mothership.

People have laughed, cried, and told stories of one kind or another. Three thousand years have passed in a hurry, and even the civilization of the earth has gradually declined, but she, the mothership, has carried 500,000 human beings, successfully reached the other side of the starry sky and helped people through the most difficult time.

This kind of reluctance is probably the emotion of parting, not only Zhang Yuan, but also Captain Zhao, Li Zhendong, Ye Kaifu and others, all of whom have similar emotions.

"There's nothing to be sad about...... The most important thing is to say goodbye to her. It's her mission! ”

Captain Zhao patted him on the shoulder.

yes, there's nothing to be sad about.

Now, the "Earth Age" is about to embark on another great journey to the stars, the large centrifugal ship is rotating evenly, and 20 years of restoration have rejuvenated this mountain-sized mothership.

This is the pride of a mothership!

The Earth Age carries more than just human ...... There is another civilization, all hope!

Zhang Yuan couldn't help but praise: "She is definitely the greatest spaceship in human history!" ”

This time, everyone sincerely hopes that the other party will reach the finish line smoothly and complete their mission.

"Thank you...... We will always remember this kindness in our hearts. ”

Gan Yaduo, the leader of the Gliese civilization, also looked back and looked at it for a long time, every time he looked at it from a distance, he would be shocked by its huge majesty, and even when it took so long to tinker, it was really hard to imagine what kind of existence the human mother civilization that built it in the first place.

It saluted respectfully, its heart filled with the ambitions of the pre-stard expedition, and ......

Li Kaiqiang, the kind of reluctance to his home planet.

But soon, its eyes became resolute again.

It's not just a deal anymore.

After 42 years of development, the two sides have formed a deep friendship, and because of the help of the Gliese civilization, the development speed of human civilization has far exceeded the original expectations of the new civilization. The design standards of the space elevator, as well as the throughput capacity of the Star Port, exceeded the original budget.

Many engineers of the Gliese civilization were also involved in the construction, and together with the great productivity of the universal factory, they also made a great contribution.

Even on the distant planet Woodoid, there is a small nuclear fuel collection site that belongs to humans!

People already have enough power to collect nuclear fuel from the surface of gaseous planets.

"This way, please."

Everyone boards a rail train and heads to the living quarters of Starport.

This civilization meeting can be regarded as the last official meeting of the two civilizations, and the main content of the discussion is about some difficulties in interstellar colonization.

Although the level of science and technology of the Gliese civilization is not bad, most of the technology is not developed by itself, and it is highly dependent on foreign countries, and it has never colonized foreign stars, so it has no experience in this area.

These things can't be made up in just over forty years.

Therefore, the human side has no intention of hiding this information privately, and it can almost be said that it is all about giving it away.

Captain Zhao said solemnly: "Friends of the Gliese civilization, this time, your target is 157J3X5 4.2 light years away, a yellow dwarf star with moderate luminous intensity, our astronomical telescope has observed several terrestrial planets with suitable gravitational environments, and I don......'t know if there is an atmosphere for the time being."

"And after all these years of observation, we have never detected an unknown electromagnetic signal, it should be an ownerless planetary system."

"I hope your luck won't be as ...... as ours"

All the attendees laughed softly. Humans have sent electromagnetic waves in the direction of "157J3X5" beforehand, but there is no response.

A map of the starry sky was displayed on the large screen, marking the route of the Earth Age.

Zhang Yuan took the lead in expressing his opinion: "I won't say much about the control engineering of the spacecraft. Even if something goes wrong, as long as it's not a big problem, you should be able to fix it......"

One of the engineer leaders of the Gliese civilization nodded, "This must be fine, don't worry." ”

In the process of repairing the ship, the engineers of the Gliese civilization also learned a lot of new knowledge, so maintaining the normal operation of the ship is quite simple.

Zhang Yuan continued: "The most important thing is the rest of the things. For example, the selection of planets, geological engineering, and the improvement of planetary atmospheres...... Professor Liu, let's first introduce the selection of planets and the development steps of underground cities......"

"Okay."

One human scientist after another came to the stage and gave a complete introduction to some of the historical experiences of human civilization in alien colonization.

The pangolins at the bottom were all very attentive to the lectures, recording, and asking questions from time to time, and they all received very good answers.

Just kidding, these valuable experiences may be life-savers!

The journey of 4.2 light years, at a speed of 7/1000 of light, would take about 600 years to reach its destination, so according to the lifespan of this group of Gliese people, they would not even need to hibernate for a long time to survive this long time.

From this point of view, long-term dormancy and long life are a good thing.

They don't have much historical baggage, and those who are willing to get on the spaceship have dragged their families on the spaceship. And those who are reluctant to get on the spaceship can almost be said to be two species.

After all the human experience was taught, the leader of the Gliese civilization came to power and expressed his heartfelt gratitude.

"May our friendship last forever."

"May we all become a greater civilization."

Bang Bang Bang!

There was warm applause in the venue, and the last meeting came to an end.
