Earth Era

The crescent moon in the sky has gradually set, and the stars have quietly hidden their figures. A bright color has appeared in the eastern sky, but that bright color is only limited to the horizon and cannot affect the entire sky and the world.

It was early in the morning, the world was still in the dark stage, and the sun had not fully risen. Very few people would choose to get up so early on this winter morning, but Xiao Yun suddenly sat up from the bed at this time, and then breathed heavily.

There was an automatic climate control in the room, but it was broken and not working. So the temperature in this room is not high, it can even be said to be a little cold. Xiao Yun's naked chest was exposed to the slightly cold air. If you look carefully, you can still see the fine beads of sweat emerging from under the skin.

I don’t know how many times it has been. Ever since Xiao Yun returned from the "Raqqa" galaxy, Xiao Yun has fallen into an endless nightmare. In the full month after returning home, Xiao Yun woke up from nightmares at least half of the mornings. Every time he woke up, Xiao Yun would break out in a cold sweat, and this time was no exception.

Those scenes have been swirling in Xiao Yun's mind. No matter how hard Xiao Yun tries to forget, they always stay in Xiao Yun's mind and refuse to leave.

The debris from the explosion, the tragic deaths of teammates, the dark sky, the ferocious monsters... all these elements intertwined into a big net in Xiao Yun's mind, entangling Xiao Yun tightly and never letting go.

In a precise sense, seventeen years have passed since this incident, but if we only count the time when Xiao Yun was awake, this time is shortened to less than five years. Because the Laqa galaxy is nine light years away from the most distant observation station of human civilization, and that observation station is... twenty-five light years away from the solar system. At a distance of thirty-four light-years, Xiao Yun spent twelve years of hibernation and a total of almost five years of waking up, sailing at twice the speed of light for seventeen years before he finally got out of La La. The Ka Galaxy returned to the solar system and its home on the earth.

Seventeen years to be precise, five years if you only count the time you were awake. But if Xiao Yun's own personal feelings are used to measure it... Xiao Yun feels that it happened yesterday. It seems that just a moment ago, my teammates died tragically, and it seems that the base that I and my teammates worked hard to build was occupied just a moment ago...

Xiao Yun panted for a few minutes before slowly calming down. Xiao Yun raised his head. I saw the familiar decorations in the room. There was already some faint light spilling into the room through the curtains, giving everything in the room a hazy beauty.

After finally confirming that he was on earth, Xiao Yun's mind stabilized. At this time, it was obviously impossible to continue sleeping, so Xiao Yun climbed out of the bed, picked up something to eat, and prepared to report to the Academy of Computing Sciences in a while.

Although such a tragic thing happened. But life still has to go on. As a member of the Academy of Computing Sciences under the Central Academy of Sciences, Xiao Yun's research tasks are also very heavy.

But at this moment, there was a knock on the door. Xiao Yun put on his coat a little irritably, walked over and opened the door, and saw two cold faces.

One of them waved the certificate marked "Deep Space Security Investigation Agency" in front of Xiao Yun, and then said: "Hello Xiao Yun, we have been ordered to investigate the attack by unknown beings in the Raqqa galaxy that you have experienced. We I have some questions to ask you and hope to get your cooperation."

Now that human civilization has truly entered the interstellar era, it has left its footprints on hundreds of alien star systems. The investigation and data collection of extraterrestrial civilizations have once again attracted people's attention. The Deep Space Security Investigation Agency is such an organization. They are responsible for investigating all events that humans encounter during space exploration activities that may be related to extraterrestrial civilizations. Therefore, what Xiao Yun experienced will inevitably attract their attention.

The truth is, count this time. Xiao Yun has been questioned by people from the Deep Space Security Investigation Agency seven or eight times since he returned to Earth. The people from the Investigation Bureau retrieved in detail the flight log of the "Stardust" spacecraft that Xiao Yun was aboard and monitored the footage. He carefully analyzed every part of the spacecraft that was damaged or affected by external objects, and repeatedly asked Xiao Yun many questions in a serious and even somewhat cumbersome manner.

This may be a sign of seriousness and responsibility for the people in the Investigation Bureau, but it is not the case for Xiao Yun. Every time he is interrogated, for Xiao Yun, it is equivalent to opening up the scars of the past again and exposing the pain in his heart again. Therefore, Xiao Yun has never been angry with the people in the Investigation Bureau.

But there is nothing that can be done about it. Cooperating with the Deep Space Security Agency's investigation has been written into the regulations for space exploration practitioners, no matter who they are or what their identity is. As long as deep space exploration is involved, the Bureau of Investigation has the power to interrogate him.

So Xiao Yun could only suppress the impatience in his heart. Xiao Yun turned around and walked into the room. He turned his back to the two people in the Investigation Bureau, and then said coldly: "Please come in."

The two Bureau officers showed no inkling of the unpopularity. They followed Xiao Yun into the room with serious faces, and then sat down opposite Xiao Yun unceremoniously. One of the investigation bureau personnel took out a recording tool, and another asked: "Xiao Yun, the Laqa galaxy belongs to a place that our human civilization has never set foot in. Human civilization has extremely strict regulations on exploring such a star field. Everyone on the Stardust spacecraft has identities and professional backgrounds related to deep space exploration. As an artificial intelligence expert, why would you follow the Stardust spacecraft to the Raqqa galaxy?"

This is the fifth time Xiao Yun has been asked this question. Xiao Yun has heard that some investigators like to repeatedly ask the same questions to the people under investigation, and then record all the answers, and compare the differences between these answers to find breakthroughs. Obviously, what Xiao Yun is facing at this moment is That's right.

But Xiao Yun knew that he was not lying. So apart from getting increasingly impatient, Xiao Yun didn't feel any panic or nervousness at all. Xiao Yun said: "The Laka Galaxy is a sub-brown dwarf galaxy, and its main star is a cold star. According to research from our Academy of Computing Sciences, we believe that a special chip material may be formed in such a cold star. Computers made using this kind of chip material will have very powerful computing capabilities. That’s why I applied to join the Stardust spacecraft after I learned that the Central Academy of Sciences had begun organizing a multi-department joint exploration plan for the Raqqa galaxy. Go."

Brown dwarfs are a strange type of star. Their mass is so low that it cannot trigger hydrogen fusion. Compared with real stars, they are more like an existence between planets and stars, or they are failed stars.

There are many such stars in the universe, but because they are too dim and the temperature is too low, it is not easy to find them.

Compared with brown dwarfs, sub-brown dwarfs are even harder to discover. Subbrown dwarfs have a lower mass than brown dwarfs, and they cannot even trigger the fusion of deuterium and lithium, but they are not like planets. Because they have the same formation process as normal stars, they are all formed due to the collapse of nebulae, and their mass is much greater than that of planets in the usual sense. To say they are stars, they are too small and too cold.

The Laca Galaxy is one such star system. Therefore, although the Laqa galaxy is only a few dozen light-years away from the solar system, human civilization has not discovered this star until recently. The Laca galaxy cannot trigger internal nuclear fusion reactions. It only maintains its stability with electron degeneracy pressure - the same form of existence as a white dwarf. But its surface temperature is much lower than that of a white dwarf, only a few hundred degrees Kelvin - this temperature is about the same as the human body.

It is precisely because during the research process Xiao Yun believed that there would be a very special material existing on this kind of star, and this special material is very suitable for developing more advanced computer chips, Xiao Yun, an artificial intelligence expert, applied to follow The Stardust spacecraft went to this star system to explore together.

After hearing Xiao Yun's answer, the researcher was silent for a moment, and then continued to ask: "Based on the information we have obtained now, we know that in the entire Academy of Computing Sciences, you are the only one who thinks that there are stars above cold stars. A special material will help in the development of new computing chips."

Xiao Yun replied angrily: "So you think it was a conspiracy for me to follow the Stardust spaceship to the Raqqa galaxy? Do you think this was a premeditated thing, and I killed everyone else on the spacecraft?" crew, and then pretended to encounter an unknown alien creature, and then I escaped alone?"

"We don't think so. We have surveillance data to prove your innocence." The investigator said, "We are just wondering... if there is any relationship... between you and those unknown alien life forms you mentioned. .”

Xiao Yun was stunned for a moment, and then asked: "Why do you say that?"

The researcher replied: "Because... there are three hundred and sixty-seven people in total, and all of them are dead except you. So do you think this is your luck? Or is it because of some necessity?" ( To be continued~^~)
