Silver Heart is a very dangerous place, and even if Xiao Yu has now reached the level of a sixth-level civilization, this has not changed. Because there are too many extreme celestial bodies in the silver heart.

This phenomenon is easy to understand, under the gravitational pull of the earth, heavy things will sink, and light things will rise relatively closely, while under the gravity of the black hole in the center of the galactic center, a large number of dense celestial bodies will gather towards the galactic center, and relatively light stars, planets and other stars will be in the periphery, these principles are the same.

The galactic heart is the densest place in the entire galaxy with the highest density of stars. There, the density of stars can even reach the point of gathering a dozen, or dozens of stars within a light-year, these crazy multi-star systems, stars mixed with all kinds of extreme stars, orbiting each other in a crazy way, and orbiting a large black hole in the center of the river system.

Yes, at the center of the Milky Way, there is a supermassive black hole, which can reach millions of times the mass of the Sun, and it controls the operation of the entire Milky Way, so that the Milky Way can gather together without falling apart.

The existence of supermassive black holes is the main liliang that created the universe. The reason why the universe is formed today is that galaxies are clustered together, and there is no star here and there is a scattered sand is mainly because of the gravitational pull of supermassive black holes.

With the development of science and technology to this day, Xiao Yu has a deep understanding of a truth, that is, every kind of life is a legend and has been developed under the influence of many factors. For example, if it weren't for the fact that many billion years ago, there was an exploding supernova near the solar system that provided enough heavy elements for the emergence of humans, humans would not have been possible. And if it weren't for the supermassive black hole at the center of the Milky Way, which brings together as many stars as the Milky Way and allows different matter to communicate with each other, humanity would not have existed.

If in the solar system. A handful of outer giants, and the disproportionately massive Moon, shielded the young Earth from crazy asteroids from outer space, and life on Earth would be wiped out at the first moment. If the moon had not created a tidal gravitational force that allowed the earth to exchange materials sufficiently, there would have been no life on the earth.

There are many, many more such conditions, so many that it is impossible to say. Under the premise of such a variety of conditions, life on earth appeared, and eventually evolved into intelligent creatures such as human beings.

But of all these premises, the supermassive black hole in the center of the river system is the largest one. In a way. Humans, no, all the creatures that are native to the galaxy, can be counted as descendants of this black hole. Without a central black hole, life in the Milky Way is impossible.

Now Xiao Yu. With a complicated mood similar to pilgrimage, he was driving fast in the direction of Yinxin.

More than a hundred years after the beginning of the curvature voyage. Xiao Yu witnessed the destruction of a star in the small universe.

The star would have been a yellow dwarf slightly larger than the Sun. It emits amazing light and heat all the time. However, the stellar energy acquisition equipment manufactured by Xiao Yu is constantly stealing its mass, and its quality is decreasing at a rate of about eight thousandths per year. The decreasing mass of the star leads to a series of subsequent events.

First of all, because the mass is reduced, its internal pressure will also be reduced. When the pressure decreases, so does the temperature. The first trigger for nuclear fusion is temperature, and the higher the temperature, the greater the pressure. The more intense the fusion reaction it takes, the more energy it releases. And as Xiao Yu continued to steal its quality, Xiao Yu saw that its luminosity was constantly decreasing, becoming dim, and gradually began to change from yellowish to dark red.

This means that its surface temperature is decreasing, which means that its radiant capacity is weakening. Xiao Yu kept stealing its quality, and its color became more and more red.

Finally, because of the loss of mass, the star changed from a yellow dwarf to a red dwarf. At this time, Xiao Yu still did not stop stealing the quality, so it began a new round of transformation, and the red light it released began to gradually dim.

It's getting darker, it's getting darker, all the way to the present. Today is a node, because from today, because the mass is too low to bring enough pressure and temperature, the nuclear fusion reaction in the core of this star has finally stopped. Without nuclear fusion, which means that it can no longer emit light and heat, it can no longer be considered a star, at least it is no longer a star in the true sense of the word.

Xiao Yu left behind hundreds of millions of images of the star, completely documenting its rapid transformation from a young star to a brown dwarf that cannot emit light. This star could have a lifespan of 10 billion years, spend its long life peacefully in space, and eventually become a red dwarf, and then spread into a planetary nebula, leaving a white dwarf in the universe as its own corpse. However, under the influence of technology, its fate has been completely and completely changed. In the course of more than 100 years, it hastily completed the rest of its lifespan that would have taken at least eight billion years to complete, and it could not even leave its own corpse.

Xiao Yu retrieved two photos from his mind. In the first photo, the star is still emitting a faint light, although it is extremely faint, but it can still be captured by the extremely sensitive optical instrument after excluding the influence of the rest of the stars in the small universe. In the second photo, the star is completely out of light.

In the first photo, the faint red light seems to be the most desperate but weakest accusation against Xiao Yu, the murderer who killed it.

Under the liliang of technology, a star is nothing at all. A major war in a sixth-level civilization could affect hundreds of stars and cause their destruction. Even if it is a fifth-level civilization, in order to encircle and intercept the fifth-level civilization alliance, Xiao Yu once carried more than a dozen stars and deliberately detonated them to cause damage to the fifth-level civilization alliance.

In the face of technology, the once mighty stars are gradually becoming weak, gradually becoming pitiful things that can be held in the palm of a civilization's hand and wantonly destroyed.

"Perhaps, it is precisely because of this that the universe hates the existence of civilization, and there is something called luck." Xiao Yu looked at the dead star and thought silently in his heart.

Xiao Yu once again destroyed a star with his own hands, turning it from a real star into a brown dwarf.

A brown dwarf is an intermediate star between a planet and a star, it is neither a planet nor a star, or it is a super-large planet, and an incomplete version of the star. A brown dwarf is not capable of hydrogen fusion, but in some locations within it, some degree of deuterium fusion may occur. This is because deuterium fusion is less demanding than hydrogen fusion. But the scale of this fusion is too small to be negligible.

Xiao Yu still hasn't stopped destroying this star, and Xiao Yu is still stealing its mass. Eventually, the temperature and pressure inside the star could not be maintained even by the simplest deuterium fusion, and it completely broke away from the stellar category and returned to the planetary category completely.

At this moment, the star, like Jupiter in the solar system, has changed from a star to a giant gas planet. The main components of stars are hydrogen and helium, and the main components of giant gas planets are also these two elements, so there is essentially no difference between stars and giant gas planets except for their mass. So when the mass of a star decreases to a certain level, it becomes a planet, and when the mass of a planet increases to a certain extent, it also becomes a star. The two can be converted into each other.

Now Xiao Yu has completed this transformation process. As the mass of this star continues to decrease and its volume continues to decrease, Xiao Yu has already assigned a large number of mass stealing instruments to work around the rest of the stars. Now this star has become a planet in the true sense of the word, but Xiao Yu still has no intention of letting it go.

There is no need for gaseous planets to exist in a small universe. It is not like stars that can provide energy for Xiao Yu, nor is it inhabited by intelligent beings like rocky planets, and it has no value to Xiao Yu. The only consequence of having no value is that it is completely destroyed by Xiao Yu, leaving nothing behind.

So, those mass-stealing instruments were still working around this planet, until its mass was completely stolen and nothing was left, and then they left here, and were assigned by Xiao Yu to another star to continue this task.

A brilliant star has completely disappeared from the universe. The purpose of its existence was simply to allow Xiao Yu's huge fleet, and the entire small universe, to advance nearly three thousand light years in a curvature way.

At this moment, Xiao Yu is manipulating a huge fleet and a small universe to stay around a star system. Because the early detection showed that there was a large number of some precious elements that Xiao Yu urgently needed in this star system, Xiao Yu needed to replenish here before he could go on the road again.

At this time, Xiao Yu received a message transmitted through space broadcasting.

"It's presumptuous, but we still make this request to you, regardless of the civilization that received this message, if you are a level 6 civilization, then, we hope you can help us...... In return, we are willing to give away this small universe to the ...... We are the Pegasus civilization. (To be continued......)
