Vol 3 Chapter 690: Dyson Ball

Chapter 690 Dyson Ball
At the moment Xiao Yu is at the junction of the edge of the Milky Way and interstellar space, and the star that suddenly disappeared is near the edge of the Milky Way. It is a very ordinary red dwarf, with a very low mass and low temperature and luminosity. It has no satellites, not even asteroids or interstellar dust orbiting it. It is orbiting a nearby binary system, like a deserted gravel.
This type of star is the most numerous and least noticeable star in the galaxy, and it has little value for low or high civilization. For a civilization that wants to rely on stellar radiation to obtain living resources, its habitable zone is too small, and it is too close to the star, and there is too much harmful radiation. For a civilization that wants to use rocky planets or asteroids to obtain resources That said, it has only one bare main star, no decent planets, and no value. For advanced civilizations that use stars as fuel, such as Xiao Yu, its size is too small to be worth the effort. In short, it belongs to the star in the galaxy that has the least sense of existence and the least attention.
But now, under the circumstances that Xiao Yu is currently searching for the traces of the Guardian civilization, its disappearance is enough to attract Xiao Yu's attention. Although it is just a red dwarf, it can make such stars disappear, at least if it is a sixth-level civilization. Moreover, there are some oddities in its disappearance.
Xiao Yu saw that it first disappeared from the visible light band and various radiation bands, and then after a period of time, it disappeared from the aspect of gravitational waves. Based on this, Xiao Yu easily came up with a corollary: there is an unknown existence that is trying to hide it. This civilization took some measures to first shield its radiation band. After the work was completed, its gravity was also shielded by the technology of gravity shielding, so that it lost its trace from the large-scale visible universe.
This phenomenon immediately aroused Xiao Yu's interest. Xiao Yu made a guess almost instantaneously: "This has a great chance to be done by the Guardian Civilization. Perhaps the Guardian Civilization is to collect such unobtrusive stars and evaporate them from the earth. Then it is quietly transported away, acting as a node on the star road. Follow it first, as long as you follow it, you can find where the guardian civilization is hiding. "
Xiao Yu made a decision instantly. So Xiao Yu immediately dispatched several special concealed miniature spacecrafts and hurried towards the place. Xiao Yu knew that the guardian civilization had probably not found his trace. Because if the guardian civilization already knew that he had laid the Tianluodi net in this place. How could they still capture stars in this area?
"As long as I don't find me ... from now on, all the detectors will go into concealment. Except for tracking the spacecraft, all other types of spacecraft will also go into concealment." Xiao Yu quickly ordered. Xiao Yu's large troops did not move, but only sent a few of the most hidden small spacecraft. It's easy to find out if you dispatch a large army. It is most appropriate to dispatch a concealed small spacecraft to obtain a position information and then dispatch a large army to go under siege.
Three ultra-miniature ships, about the size of a desk in the Earth's era, sailed with a special curvature and began to move towards where the star disappeared. It is impossible for a star to move too fast during the transportation, and the speed of this small spacecraft is enough to catch up and then quietly track.
Detectors near the star are watching it quietly. Provides direction for the tracking spaceship that is coming. During the time when the small tracking ship came. Xiao Yu's speculation was confirmed, but the confirmation of this speculation made Xiao Yu even more confused.
Although this hidden red dwarf is shielded from the radiation and gravitational bands, it is impossible for a star to completely disappear from the universe, it will always leave some traces. Until now. It has traveled a distance of more than ten light years, but above this distance, the detectors arranged by Xiao Yu in advance can still detect it.
It is very strange, since this hidden star can still be observed by Xiao Yu at a distance of ten light years. Then in the previous large-scale carpet search, why did Xiao Yu not find the star road nodes arranged by the guardian civilization? Judging from the current situation, there is only one reason why Xiao Yu could not find it, and that is, the Guardian Civilization did not arrange nodes here.
This is Xiao Yu's confirmed guess, but it is this thing that makes Xiao Yu even more confused. Because if you want to travel to the Andromeda galaxy, you will definitely set up nodes in this area. Place nodes outside this area? It's not impossible, but what's the reason? Although this can make some people unexpected, the price to pay is also too great. For example, an earth person will travel a thousand kilometers north, but he set the first supply point to the south. The same at 100 kilometers.
Gradually, another speculation emerged in Xiao Yu's heart. But this speculation is too outrageous, and Xiao Yu is not sure yet.
A year later, Xiao Yu's tracking spacecraft finally caught up with the star. With the faint reflection of starlight nearby, Xiao Yu saw what the star looked like at the moment.
It has completely changed its appearance. Xiao Yu knows that this change in appearance is due to external forces. There is a layer of black unknown material film sphere covering the entire star. It is this film that blocks most of the star's radiation, including light, infrared, ultraviolet, neutrinos, gamma rays, etc At the same time, this layer of film also has very good light absorption characteristics, and only a small part of the external star's rays will be reflected back after it shines on it. This means that it is very difficult to find in the light band. If Xiao Yu's tracking spacecraft was not equipped with very sensitive optical instruments, Xiao Yu could not see it at all.
On this large black film ball, there are some bulges, and there are some instrument-like things built there. For fear of being discovered by them, Xiao Yu didn't dare to be too close, but even at observations at such a distance, Xiao Yu probably guessed that those things should be gravity shielding instruments and related equipment to support the operation of the film. There are also devices that can bring an entire star into a curvature voyage.
"Dyson Ball? Thanks to what you think of." Xiao Yu thought for some reason.
The Dyson sphere is an idea of ​​humans in the Earth's era. Humans imagined that by constructing a large ball and enclosing the entire star in it, they could achieve the effect of using all the radiant energy of the star as their own. But in the development process of Xiao Yu, the Dyson ball did not appear at all, because it was unnecessary. From the beginning of elemental decay technology, energy is not a bad thing for Xiao Yu. The abundance of material in the galaxy can be used by Xiao Yu, why bother to build things like Dyson balls. However, Xiao Yu did not expect that Dyson ball had other functions in the hands of the guardian civilization.
That is concealment, letting a star disappear for nothing.
The actions of the guardian civilization reminded Xiao Yu of some things that happened in human society in the earth era. In some times, in places where law and order are not good, at night, people often walk around and are suddenly caught in a cloth bag, and then pulled away in the dark. Now think about it, how the star's encounter at this moment was very similar to those who were abducted at that time.
After sighing secretly in his heart, Xiao Yu controlled his small spacecraft and continued to follow. By this time, Xiao Yu had basically confirmed that the EbookFREE.me, which kidnapped the stars in a cloth bag, was at least 99% likely to be the guardian civilization.
So far, Xiao Yu has tracked this stellar capture team for more than a hundred years, and the two sides have sailed a distance of more than 8,000 light-years. When this team sailed for more than 500 light years, Xiao Yu's troops had quietly started to follow them. Five hundred light years was only a voyage of more than three years for Xiao Yu.
"Sure enough, haven't the Star Road nodes been built in this area ..." As the sailing distance became more and more distant, and the pre-determined range became more and more, the speculation in Xiao Yu's heart became more and more affirmative Get up, "It seems that your voyage target is not the Andromeda galaxy ..."
It seems that at the beginning, when he heard that the Guardian civilization was going to voyage across the river, Xiao Yu subconsciously believed that the voyage target of the Guardian civilization was the Andromeda galaxy. Because people go higher, in the local galaxy group, the Andromeda galaxy is the only galaxy larger than the Milky Way galaxy. Voyages in the river system will undoubtedly have more room for development in the Andromeda galaxy. But the guardian civilization did something unexpected, and they did not choose their destination in the Andromeda galaxy.
So far, Xiao Yu has basically affirmed this, but Xiao Yu has yet to know where the guardian civilization chose the destination. This can only be inferred after seeing the location of the guardian Wenxing Road node.
Time passed by bit by bit. After the star was towed for more than two hundred years, the star-catching unit of the guardian civilization finally stopped. Xiao Yu, hiding in the dark, saw that at least thousands of similar stars have stayed here ... (to be continued ...)
