Obviously, Lu Yu would never get out of the Silver Star.

And the other party's communication conditions are also very strange, given that this unknown civilization has always had strange behaviors, this request seems not to be much abnormal.

The triangular spaceship outside the light bridge returned to the vicinity, but this time it did not approach recklessly, but quietly levitated outside.

Perhaps it was impossible to communicate after trying various methods, the optical bridge shielded the signal in the large universe, and in the end, the triangular spacecraft could only use the most primitive optical signal to convey information at a flickering frequency.

"Horned civilization, are you okay inside?"

"Why don't we retreat!"

"After that, I'll just think about it slowly."

Well...... I don't know if it's an illusion, how did a good eighth-level civilization come up with the taste of licking a dog?

However, Lu Yu soon realized that what the triangle spacecraft was afraid of was that he, a so-called friend of civilization, would cooperate with this unknown civilization.

And the Ring civilization ...... will be a sacrifice for their cooperation.

Although Lu Yu regarded the triangular spacecraft as a bridge to earn points, he didn't really think about crossing the river and demolishing the bridge, after all, this guy still owes him space technology!

Ignoring the triangle spaceship that was flickering more and more rapidly, Lu Yu looked at the light bridge in front of him and replied indifferently to the message of refusal.

Of course, in the universal language of the universe.

Lu Yu is no longer in the survival stage, and before returning to Blue Star, he plans to stay in the Silver Star all the time.

Even......... Back at Blue Star, maybe he'll have to stay in it for a long time.

In the light bridge, if there is a slight mistake, you can jump away immediately.

It's just that after Lu Yu's decisive refusal, the unknown civilization didn't reply for a long time as if it was stuck in a shell.

And the triangular spaceship, which was also waiting outside, even squeezed out the last stored mass to launch an attack, trying to interrupt the communication between the horned civilization and the unknown civilization.

But it was also in vain.

Mass represents energy, and the blow it had previously used to cut through space consumed most of its stored matter had no effect, not to mention that it was no longer a threatening attack.

It's just that such a provocative behavior of the triangular spaceship still didn't get a reaction from an unknown civilization, and three days after Lu Yu refused, he didn't even receive any reply.

"Is the life form of a higher civilization a strange concept of time?"

"Or is the communication between the higher civilizations so slow?"

As a carbon-based life that has not undergone body modification, Lu Yu really can't accept such a slow speed of communication.

Moreover, human scientists speculate that with the upgrading of computers, communication should be more rapid with the support of huge computing power.

This is undoubtedly another exposure of the strangeness of this unknown civilization.

It's weird!

So much so that Lu Yu was already a little speechless.

This unknown civilization said in the next second that it would dedicate all its technology trees and make friends with the Horn Clan, and Lu Yu would not be surprised.

But this kind of beautiful thing didn't happen in the end.

And reply...... still didn't wait, at this time, it had been half a month since the Silver Star entered the light bridge.

It was like a starry sky scroll spread out, and at this time, the ability was finally exhausted.

The two-dimensionalization, or the decay of the void, only extended about 0.1 light-years before ushering in the end.

Everything that has fallen into the second dimension has acquired three-dimensional properties, but it also means that their structure has been destroyed again, and a large amount of energy has swept through this star field.

And among them, it is still the three spaceships that are still as immobile as a mountain.

The fiery tide of energy could not even affect the bridge of light, which stretched an astronomical distance.

………

Earn points!

No chills!

This comforting Lu Yu can only let the Silver Star, which can leave at any time, still stay on the Bridge of Light.

And at this time he was far away too

In the penoline.

Three space battleships with special missions finally stopped at the Great Wall of Space base.

Since then, the military exercise has lasted more than 80 Earth days since the ignition and take-off of the Lagrange Space City. The unusually smooth journey and the unexpected power of the battleship's engines in space brought everyone almost a month and a half earlier than expected.

And this is already a speed unimaginable to humans.

Voyager 1, which used to depart from Blue Star, took 44 years to reach the Kuiper Belt, but now it takes less than three months for the spacecraft to get them from Blue Star to the edge of the solar system.

Whoever has to sigh, the progress of science and technology.

"Hey, hey, hey, one of the rest times is divided into three shifts, which is 10 days per shift! It's a pity that I can't take a break with you. Otherwise, we can go to the famous "good place" in the base together to relax and unwind together!"

When Yang Weili saw Bona's lewd and weird smile, there was only one thought in his mind - thank goodness he finally didn't have to take a turn with this guy!

Boehner was one of the first officers to leave the ship, and as a result, Yang Weili did not see this guy appear in the Penglai for six days. It wasn't until the seventh day that I saw a pale-faced and vain Bona appear in the dormitory, and it seemed that there was only one step left to be squeezed dry!

This X seems to be a person who almost lost contact with the guy who lost contact with X and fell asleep for a day and a night, and then came back to life on the spot, and said hello to Yang Weili early on the ninth day and left Penglai.

I thought that Bona was going to disappear until the end of the rest time, but when it was time for dinner, Bona unexpectedly appeared in the ship's cafeteria.

"I'll tell you! Today, I saw that a large number of old scientists seemed to be preparing to return to the Blue Star, as if the Blue Star would have some big strategy to ask their opinions....... you said we wouldn't suddenly stop the exercise, right?"

"Hmm."

"Why aren't you curious?"

"It's all expected, because our fleet also has a stealth mission to open up the shipping lanes of the solar system, and our early arrival this time gives Blue Star full confidence...... I'm afraid that the scientists who have returned will not stop at the forward base, and will go directly to the Blue Star, and maybe they will be able to go back and forth in three months."

Yang Weili's analysis blocked Bona's mouth and made him lose his curiosity about this matter.

"Cut, I'll have a good rest on the last day of tomorrow! This time it almost killed me! "Good place" I've figured it out for you! Locations and so on will be pushed to ...... one by one Oops! Why didn't you finish eating?!"

Human biology determines that the desire to reproduce is rooted in genes, and how to deal with physiological problems during long voyages is also a major issue.

The rapid development of human civilization has made human beings go to space without even starting self-transformation, and in the face of impulses engraved in genes, unless inhumane castration is carried out, there are not too many good ways to come up with them at this stage, which is nothing more than that long-term voyage transport ships will have accompanying the ship, and military spaceships are much more difficult, except for some auxiliary data in virtual reality, they can only be solved by devices.

Some of the mentally clean Yang Weili couldn't accept the repeated use of the imitation people, and deleted the positions shared by Bona one by one.

Another day passed, and the first officers of the Ponlai returned to the ship after their ten-day Earth Day break. It was the turn of the second group of officers to go out to relax, and Yang Weili was among them.

Compared with the advance base, the Great Wall of Space base, which has only been built in the first phase, is much smaller in terms of population and function. The base, with a fixed population of just over 7,000 people, covers an area of about 20 square kilometers and has only a large number of scientific research laboratory modules.

Most of them are researchers or engineers, and most of them work at both the post and the dormitory. As a result, the business here is extremely backward, and it is usually an intelligent person who takes care of it according to the set program, and there is not much breath of life.

After walking around the living quarters the size of three streets, taking a lot of photos of his parents, and ignoring his sister, who was asking for many Martian specialties, Yang Weili walked into the base with a cup of coffee that was said to be from the earth and a box of pineapple buns that had just been baked

in the library.

There is a lot of deep space information in this, and Yang Weili, who also has an astronomy degree, has been fascinated for a long time!

A cup of coffee, a box of pineapple buns, and a day at the library!

Perhaps this is the life that Yang Weili yearns for the most, and he often thinks that if he hadn't become an officer, he might have become a librarian after graduation!

When he finished browsing the information, he received a new email on his personal laptop.

[Major Yang Weili, your application for visit has been approved. 】

[Your e-permit for the visit will be sent with the email.] 】

[If you have a need, you can apply for a simulated body as a guide before entering the visit module, as your .........]

Yang Weili hurriedly ate the remaining half of the pineapple bun in one go and walked out of the library.

The intelligence here is even more obvious than on the blue star, as long as the appointment is made on the personal computer of the bracelet, the moment he walked out of the library, a droplet-shaped unmanned hovering car arrived at the door of the library at the same time.

Everything was designed in an efficient and concise direction, and with the pass, the hovercar was not even blocked for inspection, and Yang Weili was taken all the way to the area he wanted to visit.

The Great Wall of Space Base is located on a large asteroid in the Kuiper Belt.

The Coyinbo belt, also known as the Leonard-Coyinbo belt, is located on the outer side of Neptune's orbit (about 30 AU from the Sun) in the solar system, in a dense disk-like region of celestial bodies near the ecliptic plane, it is similar to the asteroid belt, but the range is much larger, it is 20 times wider than the asteroid and 20 to 200 times heavier.

There is more material to be used here, and the location chosen for the Great Wall of Space base is the direction in which the unknown fleet will reach the solar system nine years later.

Humanity will use this base as the core to establish a line of defense to defend the home planet.

Yang Weili overlooked the huge base still under construction, which is the second phase of the Great Wall of Space Base.

It is theoretically the largest shipyard that humans can build, and most of the 3,000 space warships planned for the future will come from here.

Since it is the production base of human future warships, the best building materials must be used, all kinds of technologies must be used the best, and the performance must also be the best.

This super-giant dock, which is still under construction, has reached more than 100 kilometers at its longest point, more than 30 kilometers at its widest point, and 2 kilometers at its thickest point, with a total area of more than 2,000 square kilometers.

The dockyard is brightly lit, and it is full of shuttle instruments and intelligent robots.

The special locomotive that specializes in the transportation task inside the dock is shuttling back and forth, accurately transporting batches of building materials to the designated place, the hoisting equipment installed with self-driving instruments is assembling huge building materials to the behemoth in front of them, and countless intelligent robots are nervously laying lines and welding materials at the connection.

Only high-end parts will be manually operated, but they are only controlled by virtual reality, and after completing one place, they will seamlessly connect to another, and only intelligent robots are on site.

In this super-giant dock, there are at least 10,000 automated factories that produce various types of spacecraft parts, and the computing modules, energy transmission modules, lighting equipment, etc. used inside the spacecraft can all be produced by these factories.

Outside the dockyard, there is a transport fleet of hundreds of ships, which are transporting large quantities of preliminarily smelted building materials from the asteroids of the Kuiper Belt day and night.

The frightening efficiency allowed Yang to witness the shipyard being built at a speed visible to the naked eye.

"I'm afraid that's the only way that humanity can have the confidence to keep that unknown fleet out of the solar system, right?"

"I don't know, how terrifying will the production speed of a shipyard of this size be when it is running at full capacity?"

"The Penglai is almost three months to build on the Blue Star right now. And here, it may only take a week? Three days?"

"Maybe I'll be able to witness it when I come back from the Oort Nebula from the exercise mission!"

Yang Weili selected a certain area of the dock, and the hovertruck quickly sent him to the designated location.

He had just gotten out of the car when an intelligent simulant came to his side.

"Hello, Major Yang."

"I'm your guide K2314D23."

This impersonant will also play the role of protection and surveillance, if Yang Weili has any actions that endanger the base, after obtaining the authorization of the administrator, he will eat the iron fist from the impersonator.

Of course, Yang Weili didn't have any anti-human thoughts, he just wanted to take a good look at this ergonomic miracle that was still under construction.

"Look here, this is the latest type of virtual sun, the light it emits has been improved by the latest technology, completely eliminating the harmful rays mixed in ordinary light, and living under such light for a long time is very good for human health."

The impersonant said as he guided Yang Weili forward.

At this time, the dock has not yet been fully built, and the interior is still cluttered, with piles of building materials everywhere, various pipes and lines exposed, and intelligent machinery shuttling and busy everywhere.

But all this can't stop Yang Weili's beautiful imagination.

He sees not only the interstellar war that may be coming, but also the future of humanity after the war, based on the shipyard that has released a powerful production capacity, and the whole people will step into the interstellar age.

The Great Wall of Space is not only the key to defending mankind, but also an important pedal for mankind to move towards the starry sky!
