Through the lens of these dedicated probes, Xiao Yu carefully observed the surface of the star. As the distance gets closer, the star becomes more luminous and larger.

At a distance of only 50 million kilometers, the star looks like a millstone, and at a distance of 20 million kilometers, it has become the size of a house and is so bright that it is impossible to look at directly. When the distance was reduced to three million kilometers, it had already occupied Xiao Yu's entire lens. Of course, above this distance, Xiao Yu's probe had already dodged to the side covered by the ghost clan to avoid the star's amazing energy.

In fact, strictly speaking, a star, like a gas giant, has no clear boundaries. The farther away they are from the host star, the thinner the matter, and the closer they are, the higher the density of matter, and the density of matter from low to high is a gradual process, and they do not have a solid surface like rocky planets.

Xiao Yu speculated that at a distance of three million kilometers from this star, if there was no ghost race covering here, his probes should have already touched the surface atmosphere of this star.

Above this distance, the radiation energy of the star reaches an alarming level, and the various high-energy charged particle streams, that is, the stellar winds, are unusually strong, and any device that relies on radio communication is paralyzed here due to the influence of various radiation, various particle flows. The light here is so intense that it almost overwhelms the matter. At this distance, if the influence of stellar gravity is excluded, the propulsion of these rays alone can accelerate Xiao Yu's instrument from a standstill to a speed of tens of kilometers per second.

This is the light pressure. Photons do not have a resting mass, but they carry energy in motion. In the age of the earth. Humans have also used the light pressure of sunlight to carry out interstellar travel, but it has not been implemented later due to various reasons. After Xiao Yu has mastered the technology of controlled nuclear fusion, there is no need to use light pressure.

The star is only a medium-sized star. There is even a class of giant blue stars in the universe whose luminosity can even reach or temporarily exceed the Eddington luminosity limit, that is, the outward pressure of light exceeds the star's own gravitational pull. When this happens, a large amount of stellar material will be pushed away from the star by its own light pressure and thrown into space. Because the discarding of matter reduces the luminosity of the star, its luminosity falls below the Eddington luminosity limit. This is the kind of giant star that maintains its own dangerous equilibrium in this state.

That kind of crazy star, thinking about it makes Xiao Yu feel cold. In the midst of astronautics. Xiao Yu would rather detour nearly a hundred light-years more than get close to them, that kind of star is really unprovoked, maybe they will explode at any time, and at the same time as they directly become a black hole. Wipe out all living creatures in the vicinity for hundreds of light-years.

Thankfully, there are only a handful of stars in the universe. Xiao Yucai doesn't have to worry about the supernova explosion affecting him all the time.

After Xiao Yu's probe and the star were closer to three million kilometers. Xiao Yu began to manipulate his probes to accelerate in reverse. This is a necessary procedure, and if you don't do this, the gravitational pull of the star will keep speeding them up, eventually causing them to hit them directly.

Because of the angle, this star is just a curved crescent moon shape in Xiao Yu's eyes at this moment. But just the crescent moon that leaked out heated the surface of Xiao Yu's detector, which was two million kilometers away, to more than 300 degrees Celsius.

At this distance, the exact shape of the crescent moon is not discernible in a full-luminosity photograph because the light is too intense. causes it to look like an irregularly shaped polygonal star. Only after reducing the luminosity by a factor of hundreds or thousands can you barely see its original shape.

Fortunately, Xiao Yu's detectors all use ultra-distance communication, and the internal instruments of the detector are all equipped with the strongest anti-radiation materials, so they are not affected by the radiation of this crescent.

This is the closest Xiao Yu has been to a star in more than 10,000 years. The last time I got so close to a star was when I made a circumsolar trip in the solar system. The previous binary system could not be counted, because a brown dwarf could not be considered a real star at all.

"The power of a star is something you can never experience if you don't get close to it." Xiao Yu sighed secretly in his heart.

Xiao Yu aimed the probe's camera at the half of the star that was covered by the ghost race. What Xiao Yu saw was a vast black plain. That's right, under the cover of the Ghost Clan, the surface of this star has become an extremely gentle plain, with little undulation.

The stellar atmosphere here is also gone. Because of the Ghost Race's cover, only half of the star's atmosphere remains. Xiao Yu speculated that this half of the star's atmosphere may have been frozen into liquid or solid because of the isolation of heat, and finally fell to the surface of the star.

That's the Ghost Clan's big deal. Stars that don't have a fixed surface are pressed out of a surface by the ghost race.

After continuing to get closer, Xiao Yu realized that all his previous preparations had been in vain. Here, indeed, as the Ghost Clan said, all heat, all radiation is cut off by it. Therefore, on this side of the star, except for the strong gravitational pull, there is no difference from interstellar space, the same cold, the same cold.

After the distance was reduced to 200,000 kilometers, Xiao Yu could no longer see the full picture of the star. In Xiao Yu's eyes, all of them were the kind of black plains that didn't have much ups and downs, endless, and boundless. At this distance, the crescent-shaped star was also blocked behind because of the angle.

"Senior, I'm here." Xiao Yu sent a radio broadcast to the star.

The reply from the Ghost Clan came quickly: "The surface of the stars here has been crushed solid by me, and you can land here as you like." After landing, do whatever you want to study, don't bother me again for a short time, I'm tired and need to rest. ”

"Haode, senior, go and rest." Xiao Yu said respectfully.

I don't know weishenme, at this time, Xiao Yu remembered the old cat he raised when he was on the earth. Every winter, the old cat always lazily leaned against the fireplace, closed its eyes and refused to move, and every time it had to rely on the servant to bring cat food to its mouth, it would eat a little, and then continue to rest.

At that time, Xiao Yu knew that this old cat would not live long. The facts did not exceed Xiao Yu's expectations, and the old cat died before he even made it through that winter.

"Even if you are as strong as you, do you have such a time when you are old and about to die?" Looking at this ghost clan who was once strong and brilliant, but now he only looked like a twilight old man, Xiao Yu had mixed feelings in his heart.

Thousands of specialized probes have landed on the star's surface in different locations. The gravitational pull here is hundreds of times that of the Earth, and if a person lands here, then in an instant, he will be crushed to the bone, and his body will be crushed into a thin sheet under his own weight. However, Xiao Yu's detectors were built with the environment in mind, so they will not be affected by these strong gravitational forces.

It wasn't until he landed on the surface of the star that Xiao Yu discovered the true situation here. At the foot of Xiao Yu's instrument was a layer of black translucent object that seemed to be very thin, but extremely tough. Through this layer of objects, you can even see the surface of the star up close.

These things attracted Xiao Yu's full attention. At such a close distance, it can even be said that there are not many opportunities to observe the surface of the star at zero distance, so Xiao Yu naturally has to cherish it.

"This translucent black film should be the body of the predecessor of the ghost clan. The predecessors of the ghost clan said that it was illogical and did not exist in this universe, but it was a miracle that an existence with zero total mass and total energy actually showed an entity, and it was so tenacious that even a star could not be damaged in the slightest. ”

"When the Ghost Clan's predecessors were at their strongest, it is estimated that even a natural neutron star, or a white dwarf, could not damage its body structure. Come to think of it, a badly injured and dying sixth-level beast can survive on the surface of the white dwarf, not to mention the ghost clan seniors who can go head-to-head with the neutron battle star. ”

Xiao Yu thought secretly.

Through this translucent black film, Xiao Yu carefully observed the stellar material beneath it.

This black film seems to have an extremely superior light-blocking function, and through its filtering, the stellar material appears in front of Xiao Yu with a faint yellow color. This is in line with Xiao Yu's previous inference based on the principle of blackbody radiation. According to the principle of blackbody radiation, a star of this mass, this temperature, should have been yellow in the first place.

These yellow, fluid-like stellar materials were surging angrily at the foot of the instrument Xiao Yu had made, like a crazy sea. However, no matter how violent their movements and how huge their energy is, they have never been able to break through the barrier of this black film. At most, this layer of black film is lifted up to a small bump no more than 100 meters high, which looks like a small dirt mountain on the black plain.

The strength of the ghost clan is fully revealed at this moment. (To be continued......)
