Long galaxy, endless journey, Xiao Yu's huge fleet, compared to the vast galaxy, is like a humble ant, trying its best to explore its current land.

This yellow dwarf star was ruled out by Xiao Yu without accident. There is only one planet in this star system, and it is too close to the main star, and the dense atmosphere keeps the heat of the star on the surface as much as possible, making the planet's environment feel like a legendary lava hell. Here, Xiao Yu did not find any traces of the existence of life.

Xiao Yu's fleet has been sailing at a curvature of thirty-five times the speed of light, and after reaching the destination, it will send a probe to explore the target star system, and the main fleet will not stop, it will be too wasteful of time.

The course of Xiao Yu's fleet is not to maintain a straight line, but to sail a distance here and there. The distribution of stars is three-dimensional, and how to design a closest course among so many targets is also a science.

The distance of a few hundred light years is nothing to Xiao Yu. In fact, in the more than 10,000 years of journey after leaving the earth, Xiao Yu has at least completed a long journey of nearly 20,000 light years. Now, Xiao Yu is less than 10,000 light-years away from the silver heart.

It's still a long way off, but the types of stars are slowly changing. Xiao Yu observed that the closer to the silver heart, the more aging stars there were. And around an aging star, it is clearly not suitable for life. So Xiao Yu decisively changed the direction of exploration and began to explore to the side, instead of continuing to approach Yinxin.

The environment of the silver heart is much more sinister than the outer environment. Here, the density of stars is very high, and multi-body star systems can be seen everywhere, with two or three here and there. And even more stars are circling each other, moving chaotically. From time to time, some aging stars end their lives with violent explosions.

This is not the most terrifying, Xiao Yu is here, and he is fortunate to witness some of the most violent energy explosions in the universe, which are unstable against supernovae.

Instability is a very special way of supernova explosion for supernovae. Before the explosion of this type of supernova, its host star was a huge star with at least one hundred and twenty times the mass of the Sun. This star explodes in a peculiar way, after a supernova explosion, nothing is left in its core, no neutron stars, no black holes. All the matter that made it up would be completely shattered in this violent explosion. All matter that is more than 100 times the mass of the sun will be thrown into space. So you can imagine what a violent event it would be.

Fortunately, this time, the instability observed by Xiao Yu was more than 5,000 light-years away from him, so it did not have too serious an impact on Xiao Yu.

"It's like something heavy sinks. Light things will rise like neutron stars. White dwarf. A heavy thing like a black hole, under the influence of the supermassive black hole in the center of the galaxy, will show a tendency to sink slowly, and eventually gather in the center of the galaxy. Can Yujian, in the Silver Heart area, is a paradise for all kinds of extreme celestial bodies. Stars such as stars or planets. Here it can only be insignificant things that are devoured and toyed with. Such a place, until I reach the sixth level civilization, I should not approach it first. Xiao Yu pondered. Such a decision was made.

It can be yujian, in a place like Yinxin, it is definitely an area with a high incidence of various extreme events. Neutron stars and black holes are quite rare in the outer reaches of the Milky Way, but they are ubiquitous here. If the situation is not good, they will also collide under the influence of various environments. Previously, in the fifth-level danger zone left by the silicon-based civilization, a white dwarf star collided with a neutron star to explode with such powerful energy, not to mention extreme events such as a neutron star collision or a black hole devouring a neutron star.

After changing direction, Xiao Yu's exploration continued.

By now, Xiao Yu's exploration has lasted for more than three hundred years, and has traveled at least eight thousand light-years away. What he saw and heard along the way gave Xiao Yu an eye-opening feeling. Such a long trip is very beneficial for Xiao Yu to refine his theory of celestial evolution.

In the past three hundred years, something has also happened within the Shenzhou civilization. Under Xiao Yu's close surveillance, Xu Junpo finally grew up, entered the Central Academy of Sciences, and began to carry out various scientific research activities under the personal leadership of Luca III. He is like a shining star, slowly rising within the Shenzhou civilization.

His performance did not disappoint Xiao Yu. In just a few hundred years, his achievements and numerous accolades have proven that he is outstanding.

The total number of intelligent creatures has now reached more than 130 billion, and the total number of scientists has finally exceeded 1 million. These more than one million scientists have been enriched into various branches and research institutes under the Central Academy of Sciences according to different specialties and scientific research directions, like parts on a huge machine, contributing their liliang to the Shenzhou civilization.

During this long journey of more than 300 years, Xiao Yu's huge fleet also took a short break for ten years. The demand for energy for curvature navigation is too huge, even if Xiao Yu has reserved resources as much as possible when he leaves that galaxy, there is still no way to support it for too long. Fortunately, this is a voyage within the river system, and there are various stars everywhere around, which can be used by Xiao Yu to replenish resources at any time.

"Is life really so scarce?" Xiao Yu thought with some sighs, "I've been looking for so long, but I haven't found a planet that has even the most basic life forms. ”

In this regard, Xiao Yu was mentally prepared early on. The long journey continued, and after a long period of more than 80 years after this break, the turning point finally appeared.

It was about 11,000 light-years away from the galactic center and about 18,000 light-years away from the solar system. Xiao Yu's fleet sailed out of curvature and suddenly appeared in the visible universe, silently observing a red dwarf star in the distance, about three light-years.

This red dwarf star clearly exhibits the characteristics of a living galaxy. Moreover, it is definitely a civilization station that is at least level four. Because, through a high-precision optical telescope, Xiao Yu found a very bright ring next to the red dwarf. The ring is only about 50 meters in diameter, the surface is very flat and smooth, but the length is more than 200 million kilometers. It is located on the ecliptic plane of this star system, slowly orbiting the red dwarf.

Xiao Yu knew very well what this thing was. This is clearly a large particle collider of a ringed star. And the civilizations that have the ability to make such things are at least fourth-level civilizations. Although a third-level civilization also has the ability to navigate within a star system, Xiao Yu does not think that a third-level civilization will have the ability to build such a great building.

"Is it still a continuous structure, not a segmented structure? This civilization is clearly lagging behind me. I used a segmented structure for the Large Particle Collider, and then I used an energy shield to construct the body, which was much easier to build and much more efficient than a continuous structure. This is most likely a fourth-level civilization. But...... The fourth-level civilization is the fourth-level civilization, after wandering in the universe for so long, there is a fourth-level civilization that is also haode. ”

This civilization is not a fifth-level civilization, which makes Xiao Yu a little disappointed. However, Xiao Yu still did not intend to let it go. You must know that even if it is a fourth-level civilization, its technology tree may involve some aspects that Xiao Yu has not mastered. Although these things are not as good as the special technology of the fifth-level civilization, they still have a certain enlightening significance for Xiao Yu.

After a short stay, Xiao Yu's fleet once again entered the curvature voyage and began to approach the star system.

"For me now, a fourth-level civilization is something that can be easily destroyed. So...... Will the intelligent creatures of this civilization also be included in the Shenzhou civilization? There are a total of twenty continent-class homecraft ships, which can carry up to 600 billion intelligent creatures. It's also a waste to have so many continent-class Homeland ships idle. Well, the more intelligent creatures there are, the better. I don't like to come as much as I want. So good, that's it. ”

Xiao Yu made this decision quickly. If you want to recover a fourth-level civilization, it is not difficult for Xiao Yu now, but the difficulty is to completely and completely subdue them. This requires a certain amount of skill. But it doesn't matter, Xiao Yu has absolute strength to rely on, under the suppression of the huge fleet, after using some small means, Xiao Yu can achieve his goal.

But after getting closer to less than a light year, Xiao Yu noticed something strange. At this distance, Xiao Yu can see more details inside this star system and obtain more information. So, Xiao Yu discovered this thing that interested him quite a lot.

It was a vast fleet of millions of ships. Through the analysis of optical signals and data on architectural engineering and spaceship construction, it can be known that these spaceships are obviously warships.

The ships were neatly arranged in the galaxy, as if waiting for some kind of enemy.

"This ...... You can't be waiting for me, right? Xiao Yu had such a thought in his heart, but he dispelled it instantly, "It definitely won't be waiting for me." It looks like they're facing a war. Very good, then I'll watch the play first. (To be continued......)
