With the development of science and technology to the current level, Xiao Yu has the confidence and confidence to make such a promise. Anyway, in Xiao Yu's opinion, everything is just a consumption of computing power. It takes a lot less computing power to make some amusement facilities, cook some food, or use biotechnology to breed a few things that they think are "beautiful women" than it would take to study the technology yourself.

It's a sure-fire deal.

The treatment of the Lucca civilization was somewhat different from that of the captured civilizations. After this long time together, the ability and loyalty of the scientists of the Lucca civilization have been verified, and the treatment that Xiao Yu gave them, in addition to the material life treatment that is equal to or even beyond the other civilizations, there is also the most precious thing that the rest of the civilizations extremely look forward to and dare not hope for - dignity.

No matter how much Xiao Yu did for those captured alien scientists and how much treatment he gave them, in Xiao Yu's eyes, they were always just a piece of goods, and when they encountered danger or were not of equal value, they would be abandoned by Xiao Yu without hesitation. Lucca creatures don't. If it wasn't Lucca scientists who fell into the Azure Market at the beginning, but scientists from other civilizations, whether Xiao Yu would save them or not, it would be a matter of two things.

During the period of entering the curvature voyage, Xiao Yu held an extremely grand award ceremony for Lucca II, and gave it the most honorable status in Lucca civilization. Looking at the slightly envious and jealous eyes of Luca No. 3 and Luca No. 4, Xiao Yu was very proud in his heart: "It is precisely because of your envy and jealousy of Luca No. 2 that you have the motivation to work harder for me." ”

In stark contrast to the captured creatures of the Merian civilization. Xiao Yu had lost his patience to recruit them, because Xiao Yu found that no matter what means he used, it would not work for them. Differentiation doesn't work. Discriminatory treatment does not work, and bloody punishment does not work.

"I don't know how the creatures within their civilization can have such strong loyalty." Xiao Yu thought stupidly, and simply froze them all, saving a little resource while saving worry. Xiao Yu plans to sell them all after they are thawed and resurrected after encountering the trading market.

Time is just such a flourishing. Slip away in a state of vitality.

Gradually, twenty years have passed, and the fleet of the Molian civilization has never caught up. This point, when it makes Xiao Yu's heart relax a little. There are also some doubts.

"Could it be that a faster-than-light detection instrument based on tachyon technology. There will be some kind of restrictions. Or maybe I was running too fast and they didn't have time to catch me? That's why you didn't chase after you? Kindness...... Anyway, it's always haode if you don't chase it. I've escaped two hundred and fifty light-years away, and that's far enough, right here, there's a star here. There's also a planet orbiting it, which is a great place to develop technology. Xiao Yu thought and retreated from the curvature voyage.

"It's so beautiful to see the starry sky again." Exit from the curvature of the voyage. Xiao Yu, who once again received the visible light signal, looked at the beautiful starry sky and couldn't help but sigh.

The pitch-black universe is like a huge black cloth that fills the heavens and the earth, and on this black cloth, the stars are like beautiful gems dotted on it. There is a certain pattern in the density distribution of gemstones, the more you go to the opposite place of Xiao Yu's sailing, the more sparse it becomes, and the further forward it becomes, the denser it becomes.

Here, the Milky Way can be seen clearly, and its shape is somewhat different from what you see on Earth. On a clear summer night, the Milky Way seen above the earth was in the shape of a long ribbon, and in Xiao Yu's position, the shape of the Milky Way showed a circular trend, which changed from a belt to an extremely flat oval.

Moreover, from Xiao Yu's position, several cantilever arms of the Milky Way can be clearly distinguished, such as the Perseus arm, the swan arm, etc. Even the Orion Arm, where the sun is located, is impressively visible.

This shows that in the more than 10,000 years since leaving the earth, Xiao Yu, who has been running around, has left the scope of the Orion Arm. By comparing the Heroes Sky Record with the measurements of some benchmark neutron stars, Xiao Yu found out where he was currently located.

"I ...... Probably a little outside the middle of the centaur arm, it is almost 5,000 light-years away from the current sun. Hey, when you have time, I'd better go back to my hometown and have a look. Xiao Yu sighed, "I don't know if any other creatures have entered the solar system during this time, and I don't know if the base I left on Titan is still there." Those wood spirits, as well as Venus and Mars, I don't know what the situation is now. ”

Xiao Yu looked at the direction of the sun, his thoughts were stirring, and he walked towards the target star in a conventional way.

Here, there is a relatively dense area of stars. The distance between the two nearest stars is generally not more than five light-years, which is not much different from the density of the region where the Sun is located.

Similarly, this place is about the same distance from the silver center as the sun is from the silver center, about 23,000 light years.

Xiao Yu's target star is a red dwarf star, and its mass is only 180 times the mass of Jupiter, which is less than one-fifth of the mass of the sun.

This mass means an extremely long lifespan, and there are many seemingly counterintuitive phenomena in the universe. For example, the smaller the mass of a star, the longer the lifespan, and the opposite is true for a black hole, where the more massive the black hole, the longer the lifespan. In general, matter always has a larger volume and more mass, but this is not the case with neutron stars and white dwarfs, where the smaller the volume, the greater the mass.

The planet of this red dwarf star is more appropriate to be a companion star than a planet. The companion star, a brown dwarf, has reached twenty times the mass of Jupiter. Because its mass is too small, it cannot maintain luminosity through hydrogen fusion and cannot become a main-sequence star. However, deuterium fusion can occur inside them, so there is still a certain amount of energy radiating from them. This energy is mainly emitted in the form of infrared rays.

It does not emit visible light, so these brown dwarfs are extremely difficult to observe in the universe and can only be seen by gravitational oscillation and astronomical telescopes in the infrared band.

This pair of stars, in the universe, orbit together around an invisible point. This point is their particle.

The rotation of two stars around constitutes a binary star system, and if the mass difference is not too large, then they constitute a two-body problem. Unlike the three-body or many-body problem, the two-body problem has a clear solution. Xiao Yu saw that this pair of binary stars were following a predictable and stable orbit and were moving with each other.

In this star system, to Xiao Yu's surprise, there was a rocky planet. The rocky planet is about the same mass as Mercury, and it is orbiting the brown dwarf.

Brown dwarfs, as they are called "failed stars", are a type of star between a gas giant and a low-mass star, so the planet's status is awkward. One of the definitions of a planet is that a planet must orbit a star, but whether a brown dwarf can be called a star is really worth exploring.

"Regardless of whether the brown dwarfs can be called stars or not, and whether this star with the mass of Mercury is a planet or a moon, they can bring me plenty of supplies." Xiao Yu thought about it, and threw the somewhat tangled question out of his head.

In addition to this Mercury-sized star, there are many asteroids in this binary star system, and the number is expected to reach 10 million. There are also many comets made of volatile gases, as well as dwarf planets, tiny rocks, etc., which together make up this vibrant star system.

Xiao Yu's huge fleet braved the rain of bullets and bullets to advance towards the rocky planet. Xiao Yu will be stationed here, with the help of the abundant material resources here, a comprehensive and detailed combing of his current scientific and technological system, and at the same time, speed up the research and development process of new technology, and upgrade his spacecraft again after having new achievements.

While advancing, Xiao Yu also manipulated the telescope equipped on the spacecraft to explore the surrounding stars.

"Well, the types of stars around this binary star system are quite rich, and there is actually a red giant there...... And it's fifteen times the mass of the sun. This means that a supernova explosion will occur soon. There's a yellow dwarf, and there's a red dwarf......"

Xiao Yu recorded the data while observing.

"Huh? Something is wrong with this star. After the telescope's barrel turned in the other direction and aimed at a seemingly ordinary star, Xiao Yu quickly discovered that something was wrong.

This star, only half a star.

In Xiao Yu's line of sight, only half of the star is glowing, and the other half is completely dark, not only in the visible light band, but also in the infrared and ultraviolet bands. Even, Xiao Yu couldn't even be sure if there was something there.

"What's going on? Is it possible for such a thing to exist in the universe? This star shocked Xiao Yu. If such a thing really exists in the universe, then more than 90% of Xiao Yu's scientific theories will be overthrown.

The star is undoubtedly a star, and it can be easily identified by spectroscopy of the luminous half, photometric analysis, etc. But it's only half glowing. This causes it to look like a semi-circular moon, which is unusually weird. (To be continued......)
