Thirty years later.

In the depths and vastness of interstellar space.

Inside a high-speed spaceship.

With a "bang", the hatch of the sleeping pod opened, and a naked young man sat up with his head in his hands.

Five minutes later.

The fragmented memories in his brain quickly came together, and the young man remembered who he was.

He also asked, "Grandpa, are you there?"

After waiting for a while, a voice in my head replied: "I'm here, it seems that you haven't lost too many memories this time, and you quickly remembered everything." ”

"It's only been dormant for 30 years, how can you forget so much?"

Shaking his head, Yun Xinghe muttered, but still went to the infirmary, lay down in the memory recovery machine, and recovered the small part of the lost memories - the other crew members didn't have to, but he was the captain and had to know everything well.

After the memory was recovered, he returned to the bridge control hall of the Feitian, activated the power system of the whole ship, opened the panel of the spaceship's intelligent brain system, sat in the captain's position, wrote a short log first, and then asked the intelligent brain: "Xiaokong, how is the status of the various systems of the Feitian?"

"All systems are in order, and the spacecraft is well stocked...... Captain, while you were dormant, the Flying Sky entered a meteorite-dense area, but under the control of Xiao Kong, the Flying Sky successfully crossed the meteorite area without the slightest damage. ”

"How's it going, Sora is amazing, right?"

Zhi Brain seemed to be boasting in tone.

"Good job, Sora!"

Yun Xinghe nodded, the Flying Sky Brain Xiaokong is no longer the level of intelligence before, only level 7 ordinary Brain Brain, after upgrading, the crystal stone composed of pure solid UN elements that the Tree God once stored, after clearing all the information of the Tree God (including the soul), has become the "new core" of the Wisdom Brain Xiaokong.

As soon as this new core was replaced, the intelligence level of Zhi Brain Xiaokong was immediately upgraded from level 7 to level 22, which is six levels higher than the main control brain of the D-class interstellar battleship, the computing speed has increased by 8 orders of magnitude, and the storage capacity has increased by 7 orders of magnitude.

It can be said that the core of the spaceship built with floating stones is the core hardware replacement target that almost all spaceship brains dream of.

On the Feitian, the most valuable thing now is this core.

Therefore, after the birth of Zhi Brain Xiaokong, with his powerful computing power, Berekov, who calculated the route, was almost laid off (Xiao Kong's calculation was faster and more accurate), the helmsman Sugaru was completely laid off (Xiao Kong's control was more stable), and the workload of the repair officer Du Xiaopang was reduced by more than half (the spaceship has an automatic maintenance function) - Zhi Brain Xiaokong's excellent work ability, except for the captain Yun Xinghe, everyone had a sense of crisis, and said to themselves: On this spaceship, is he a little redundant?

Yun Xinghe lazily dispelled their cranky thoughts one by one, Xiaokong is indeed strong, but after all, it is only artificial intelligence, it can help him complete 99% of things, but it is impossible to do 100%.

The remaining 1%, and the most important one, must be done with the help of these highly capable partners.

The next day, Yun Xinghe woke up all the partners.

At this time, the distance between Feitian and the hidden galaxy in front of it was less than 1 light-year.

In order to facilitate observation, the speed of the Feitian was reduced to 0.6C.

"In this large area, even the starlight can't pass through, but the gravitational fluctuations are not small, and in front of it, there is really a star system, a galaxy that hides itself. ”

Lan Xiulong said, his face was a little incredible.

A "shady curtain" with a diameter of two light-years that completely envelops the entire galaxy, what level of civilization does it take to achieve this level of technological development?

At least the Blue Star Federation can't do it to such an extent.

"It's horrible. ”

Sugaru retreated and said, "Captain, if we don't go in, in case we provoke a powerful civilization that can't be provoked, won't we put ourselves in it?"

"How is this layer of black curtain made? I don't know, this may be a technology that is difficult for us to understand, but to make the black curtain so big, its thickness must be very thin, even much thinner than atoms, most likely made of quarks, or even smaller precursors, but no matter what it is made of, it is so thin that the Flying does not need to use weapons, as long as it stabs forward, it can pierce this layer of black curtain and enter the interior of this star system. ”

"There may be danger, but not so dangerous that it is impossible to deal with it. ”

"And, if this civilization is really very powerful, why did it build a shady curtain and hide itself inside?"

"What's more, you can't hide it at all like this, and you will even completely expose yourself, a star suddenly disappears, how can this kind of thing not attract the attention of other civilizations?"

"It's tantamount to telling other civilizations: I've hidden myself, you can't see me, you can't find me?"

"Isn't this self-deception, covering one's own clothes, covering one's eyes, and telling others that he is invisible, and that no one notices him. ”

"The civilization in this star system has a very high level of science and technology, but the IQ is really not flattering, and it is bold and small to make people laugh. ”

"We can try to communicate with them, and maybe, there will be unexpected gains. ”

Yun Xinghe analyzed.

Lan Xiulong on the side nodded and said:

"This civilization, there is indeed a little problem with IQ, wrapping the stars in a confined space, light and heat cannot be dissipated, the internal temperature will definitely continue to rise, and finally reach a state of heat death, if there is really a habitable planet inside, this closed state will continue for a long time, and the habitable planet will become unlivable, which is simply a chronic suicide. ”

"You can't be completely sure of this, what if this civilization has deeper considerations? A civilization that has evolved to this level can't do such a stupid thing, right? Their scientists won't take these issues into account? Or is it a politician's brain?"

Kamura Mikoto offered her point of view, feeling that things would not be so simple.

"The universe is so big, there are no wonders, it's normal for some strange things to happen, and don't imagine the brain circuits of aliens like us. ”

Yun Xinghe smiled slightly, in fact, the old man in his brain had already told him that the civilization in this dark curtain was indeed a wonder.

And it is a strange thing that often comes up with jokes in many civilizations after the galaxy entered the era of civilization and the United Nations, and even derived a lot of idioms, sayings, and famous sayings.

But this strange civilization in the shady scenes, in some scientific and technological attainments, has come to the point of amazing other civilizations.

If we can exchange some technology from this civilization, it will be of great help to the scientific progress in some fields of the Federation.

……

A year and a half later.

The Flying Sky is approaching the edge of the black curtain.

The scene in front of me makes people feel a little creepy.

Black.

Incomparably black.

It's as black as ink.

Most of the starlight was obscured, like an all-engulfing curtain against the dim background starlight behind it.

Or rather, like an abyssal waterfall that drains down.

It was incomparably large, a huge black sphere.

Like a black hole.

It gives people a sense of not daring to approach.

Prohibitive.

But in front of this dark curtain, the Feitian rushed straight in at 0.6 times the speed of light without slowing down.

I want to pierce the shady curtain directly.

In front of the large-volume object that hit at high speed, this layer of black curtain was extremely solid, and it was not pierced immediately, but it was rapidly dented inward for dozens of kilometers, like a net bag filled with things.

But to no avail, in the end, within a ten-thousandth of a second, it was washed out of a big hole.

The Flying Sky successfully entered the dark interior.

"It's so bright!"

As soon as he entered the black curtain, Yun Qiaoqiao let out a soft shout.

It is completely different from the darkness outside, the inside of the black curtain is obviously much brighter, and due to the perennial accumulation of light and heat, it is as bright as an incandescent light bulb, and the dim light and massive photons scatter and collide everywhere inside, dispel the endless darkness, and illuminate every place clearly.

The temperature inside is also much higher than the absolute vacuum.

This brightness and temperature indicate that the existence of that layer of darkness has been at least 1,000 years. ”

"In another tens of thousands of years, maybe those frozen meteorites and comets on the edge will melt into gas, and the average temperature of the planets in close orbit will also rise by hundreds of degrees, and this star system will become a big steamer. ”

"I saw a planet in the habitable zone, and alien civilizations should be on that planet. Du Xiaopang suddenly made a fuss.

"Didi~"

"Alert!"

"Near the spaceship, a batch of tracking devices appeared, which were rapidly converging towards the spaceship, judging that they were the defense devices of alien civilizations, with a speed of about 0.25C, should they get rid of it?"

The wisdom brain is empty, and suddenly sends out a crisis reminder message.
