At this moment, the human fleet is almost reaching the Wells 0350-5658 system.

Although his ultimate goal is Wang Liang's three-star system, he is not going to go there directly at the moment, but to make a transit in this galaxy.

The Wells 0350-5658 galaxy is only about 0.6 light-years away from Chen Yue's ultimate target, the Wangliang Samsung system. Such a close distance that some studies believe that Wang Liang's three-star system is not actually a two-star system, but should be added to the Wells 0350-5658 star and regarded as a three-star system.

You must know that among the famous South Gate two-star system, one of its most famous stars and the closest star to the Sun, Proxima Centauri, is about 0.21 light-years away from the other two stars.

0.21 light-years, and 0.6 light-years, are about the same order of magnitude.

Although Proxima Centauri is 0.21 light-years away from the other two stars, a total of three stars are still revolving around each other, and there is a gravitational relationship.

According to this algorithm, the Wells 0350-5658 star, and Wang Liangsan's double star system, may also be regarded as a whole, a three-star system.

However, after detailed observations, Chen Yue still denied this view. He believes that there is no gravitational relationship between the star Wells 0350-5658 and the two stars of Wang Liang's star system. The two sides just "accidentally" passed by. After a long time, the distance between the two will become farther and farther apart, and eventually they will be completely separated.

These two are two independent wholes, there is no gravitational relationship, and they cannot be regarded as one.

Wells 0350-5658 is a brown dwarf.

Brown dwarfs can be considered incomplete stars. Its mass is too small to sustain hydrogen fusion in the core, and only deuterium or lithium fusion can be performed. As a result, their surface temperatures are extremely low, possibly only a few hundred degrees Celsius. Compared to the 6,000 degrees Celsius temperature on the surface of the sun, this temperature is really not worth mentioning.

Jupiter is the most massive planet in the solar system, 318 times the mass of Earth. It's a real big guy among planets, but it's nothing compared to stars.

Even brown dwarfs, which are considered inferior stars, are about 13 to 80 times the mass of Jupiter.

The mass of the Sun is up to 1,047 times that of Jupiter.

Wells 0350-5658 is one such brown dwarf. Its mass was measured by Chen Yue and confirmed to be 46 times the mass of Jupiter, 14,600 times the mass of the Earth, and 4.4% of the mass of the Sun.

Although its mass is much larger than that of Jupiter, its volume is only one circle larger than Jupiter, and it can even be counted as about the same size. This means that it is many times denser than Jupiter.

The brown dwarf star is also surrounded by an ice giant with a mass about the mass of Neptune. This ice giant is surrounded by many rocky moons. Its moons are no smaller than those of Jupiter in the solar system.

Chen Yue's ultimate goal is these moons of this ice giant.

At this moment, after several years of long deceleration, the huge human civilization fleet has finally arrived at the periphery of this brown dwarf.

As an aware, the human fleet did not enter the system directly. Chen Yue first sent some small spy satellites, reconnaissance spaceships, and the like to thoroughly search this star system to confirm that there were no other forces before he really began to enter.

Yes, even if the Wang Liang Samsung system, which is only 0.6 light-years away, is fighting to the death, the Wei A galaxy - this is Chen Yue's abbreviation for the Wells 0350-5658 galaxy, as for this ice giant star, it is referred to as Wei B - but there is still no one here, not even a spaceship has arrived.

Chen Yue had already mastered this information through Otto before, so he set the final destination here.

The reason for the lack of interest here is actually quite simple: this galaxy has no value.

Level 3 civilizations don't really value those more rudimentary resources, such as gold, silver, copper, iron, tin, aluminum, zinc, carbon, and so on. Because the reserves of this thing are so large, there are many of them in any galaxy, and they can't be used up at all.

The third-level civilization values some rarer compounds. These compounds are extremely difficult to manufacture artificially and produce in very low quantities, yet they are extremely versatile. These compounds are usually formed over a long period of time and in a special environment through special mechanisms.

For example, there is a common species called Torin on icy dwarf planets far from the stars. It is made of simple organic compounds such as methane and ethane that are irradiated by ultraviolet light. It is a copolymer, not a pure compound, with no definite chemical formula and no clear mixture to correspond to.

There's no way something like Torin can form on Earth. It is also difficult to manufacture it by technical and chemical means. If you want to get it in large quantities, you have to find a way to mine it on an icy dwarf star, far from the star.

Of course, Tollin is of little use for anything other than burning it. However, some special compounds or copolymers, which require a special environment and a special mechanism like Torin, and are difficult to manufacture artificially, can only be extracted from nature, but have great value.

For example, for the third-level civilization stage of science and technology creation is extremely important, according to Otto, the Southern Star civilization called blunt gold, which is widely used in the photosensitive elements of deep space detection radars, the key circuits of large-scale supercomputing, the jet ports of ion thrusters, the inner walls of high-efficiency nuclear fusion reactors, the internal circuits of ultra-distant communication equipment, and so on.

Blunt gold is probably a copolymer of some metallic elements and organic matter in a special environment, and like Tollin, there is no clear molecular formula or mixture.

Chen Yue has also entered the third-level civilization stage at this moment, and there is also a corresponding demand for blunt gold. In order to obtain blunt gold, Chen Yue developed a very complex preparation route, tossing and turning, painstakingly, and the annual output was only about 1,000 tons, which was completely insufficient.

Even to some extent, the shortage of blunt gold, as well as some other compounds or copolymers, has affected the speed of Chen Yue's industrial development.

In the binary star system, some distant and cold planets orbiting two stars at the same time, because they periodically receive different types of light and radiation from the two stars, through natural mechanisms and for a long time, relatively rich deposits of blunt gold can naturally form under their ice.

Wang Liang's three-star system is a dual-star system. At the same time, there happen to be two planets orbiting two stars.

Chen Yue knew that this was the real reason why the Southern Star Civilization and the Blue Moon Civilization were fighting in Wang Liang's three-star lineage.
