Thirty years later.

In the deep and vast interstellar space.

Inside a spaceship traveling at high speed.

With a "crash", the hatch of the sleeping cabin opened, and a naked young man sat up with his head in his arms.

five minutes later.

The fragmented memories in his mind were quickly put together, and the young man remembered who he was.

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

After waiting for a while, a voice in his head replied: "I'm here. It seems that you didn't lose too many memories this time, and you remembered everything quickly."

"It's only been dormant for 30 years. How could it be possible to forget so much?"

Shaking his head, Yun Xinghe muttered, but went to the medical room, lay down in the memory recovery machine, and recovered the small part of the lost memory - other crew members did not need to, but he was the captain and must know everything.

After the memory recovery was completed, he returned to the Feitian bridge control room, started the entire ship's power system, opened the spacecraft's brain system panel, sat in the captain's seat, first wrote a short log, and then asked the brain: "Xiao Kong, What’s the status of Feitian’s various systems?”

"Every system is normal, and the supplies on the spacecraft are sufficient... Captain, while you were sleeping, the Feitian entered a meteorite-dense area, but under Xiaokong's control, the Feitian successfully passed through the meteorite area without any damage. .”

"How about it, isn't Xiao Kong awesome?"

Zhinao said in a boastful tone.

"Well done, Sora!"

Yun Xinghe nodded. The Feitian Zhi Nao Xiao Kong is no longer as intelligent as before, and is only an ordinary level 7 brain. After upgrading, the crystal composed of pure solid UN elements that the tree god once stored Shi, after clearing all information about the tree god (including his soul), became the "new core" of Zhinao Xiaokong.

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

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

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

Therefore, after the birth of Zhi Nao Xiao Kong, with his powerful computing power, Belekov who calculated the route was almost laid off (Xiao Kong's calculations were faster and more accurate), and the helmsman Sugaru was completely laid off (Xiao Kong's control was more accurate). Smooth), repair officer Du Xiaopang's workload has been reduced by more than half (the spacecraft has an automatic maintenance function) - Zhi Nao Xiaokong's excellent working ability, except for the captain Yun Xinghe, everyone has a sense of crisis, saying to himself Soliloquy: Am I a little redundant on this spaceship?

Yun Xinghe lazily dismissed their random thoughts one by one. Xiaokong was indeed powerful, but after all, it was just artificial intelligence. It could help him complete 99% of things, but it could not do 100%.

The remaining 1%, which is also the most important 1%, must be completed with the help of these capable partners.

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

At this time, the Feitian was less than 1 light-year away from the hidden galaxy ahead.

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

"This large area cannot even be penetrated by starlight, but the gravitational fluctuations are not small. There really is a star system in front of it, a galaxy that hides itself."

Lan Xiulong said, with a look of disbelief on his face.

A "shady curtain" with a diameter of two light-years that completely envelops the entire star system. What level of scientific and technological development does a civilization need to achieve?

At least the Blue Star Federation cannot do this.

"horrible."

Sugaru retreated and said: "Captain, why don't we go in? If we provoke a powerful civilization that we cannot provoke, wouldn't we be putting ourselves in it?"

"How was this black curtain created? 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. It is very likely that it is It is composed of quarks, or even smaller protons, but no matter what it is composed of, it is so thin that the Feitian does not need to use weapons. It only needs to poke forward lightly to break through this shady curtain and enter this world. The interior of a star system.”

"There may be dangers, but they are not so dangerous that they cannot be dealt with."

"And if this civilization is really powerful, why does it build a shady curtain to hide itself inside?"

"What's more, it's impossible to hide like this, and it may even expose yourself completely. A star suddenly disappears. How could such a thing not attract the attention of other civilizations?"

"This is equivalent to telling other civilizations: I have hidden myself, you can't see me, you must not be able to find me?"

"Isn't this self-deception and deception? Take off your clothes, cover your eyes, and then tell others that he is invisible, so that no one can notice him."

"The civilization in this star system is indeed very technologically advanced, but its IQ is really unflattering, and its courage is so small that it makes people laugh."

"We can try to communicate with them. Maybe we will get unexpected results."

Yun Xinghe analyzed.

Lan Xiulong on the side nodded and said:

"This civilization does have some problems with its IQ. If the star is wrapped in a closed space, light and heat cannot escape. The internal temperature will definitely continue to rise and eventually reach a heat death state. If there is really a habitable planet inside , if this closed state lasts for a long time, the habitable planet will become uninhabitable, which is simply chronic suicide."

"It can't be completely concluded. What if this civilization has deeper considerations? A civilization that has evolved to this level shouldn't be able to do such stupid things, right? Wouldn't their scientists consider these issues? Or maybe Is it because the politicians are crazy?"

Koran Mikoto put forward her point of view and felt that things would not be that simple.

"The universe is so vast that it is full of wonders. It is normal for some weird things to happen. Also, don't imagine that the brain circuits of aliens are the same as ours."

Yun Xinghe smiled slightly and said, in fact, the old man in his mind had already told him that the civilization in this shady world was indeed a strange thing.

Moreover, after the Milky Way entered the era of the United Nations of Civilizations, it was often used as a joke among many civilizations, and even spawned many idioms, sayings, and famous sayings.

But this strange civilization in the shady world has reached a point where other civilizations are amazed by its scientific and technological achievements.

If some technologies can be exchanged 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 Feitian is approaching the edge of darkness.

The scene in front of me was a bit creepy.

black.

Extremely black.

Dark as ink.

Most of the starlight is blocked, and against the dim background starlight behind it, it looks like an all-devouring curtain.

In other words, it is like an abyss waterfall flowing down.

It is extremely huge, a huge black sphere.

Like a black hole.

It gives people a feeling of not being able to approach.

It’s daunting.

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

I want to expose the dark side directly.

In front of the large object that hit at high speed, this black curtain was extremely strong. It was not penetrated immediately. Instead, it quickly sunk inwards for dozens of kilometers, like a net bag filled with things.

But it was to no avail. In the end, a big hole was flushed out within a ten thousandth of a second.

Feitian successfully entered the shady interior.

"It's so bright!"

As soon as he entered the dark scene, Yun Qiaoqiao let out a soft cry.

Completely different from the darkness outside, the inside of the black curtain is obviously much brighter, and due to the accumulation of light and heat over the years, it is as bright as an incandescent bulb. The dim light and massive photons scatter and collide inside. Dispel the endless darkness and illuminate every place clearly.

The temperature inside is also much higher than that of absolute vacuum.

"This brightness and temperature indicate that the black curtain has existed for at least 1,000 years."

"In tens of thousands of years, maybe those frozen meteorites and comets on the edge will melt into gaseous state, and the average temperature of the planets in close orbits will also rise by hundreds of degrees, and this star system will become a large Steamer."

"I saw a planet in the habitable zone of life. Alien civilization should be on that planet." Du Xiaopang suddenly made a fuss.

"Didi~"

"alarm!"

"A group of tracking devices appeared near the spacecraft. They are quickly gathering towards the spacecraft. They are judged to be defense devices of alien civilization. The speed is about 0.25C. Do you want to get rid of them?"

Zhi Nao Xiaokong suddenly sent out a crisis reminder message.
