The aging red giant, which has become a black hole, will continue to orbit the galactic center in the same cycle as its current orbit. In fact, it does not turn into a black hole and has no effect on the rest of the galaxy. Because its quality has not changed. It is like a pebble abandoned in a corner, no one pays attention to it, no one knows what magnificent events have happened around it.

This is the first thing, Xiao Yu didn't put too much thought into this matter. The second thing is that Xiao Yu is very concerned. The picture of such a level of civilization fighting may bring some unexpected benefits to Xiao Yu.

Because of the distance, most of the details of the battle have been lost after reaching Xiao Yu's observation instruments, which leads to Xiao Yu being able to observe the war from a macroscopic perspective.

The exact location of the war, within an open star cluster. The diameter of this open cluster has reached more than 100 light years, not to mention at the edge of the Milky Way, even in the interior of the Milky Way, such an open cluster is quite huge. Inside, there are at least hundreds of stars, as well as an abundance of interstellar gas.

A huge war is happening here. Xiao Yu saw that on the side of the open star cluster, several stars suddenly lost their traces, and after disappearing for a while, they suddenly appeared again.

"This should be because Taihao's body is blocking their light." Xiao Yu guessed.

While this shadow continued to advance, from the other side of the open star cluster, Xiao Yu saw another shocking scene. Several stars on the other side, at a certain period of time, suddenly increased their brightness dozens of times, as if the flame of a candle had turned into a fire. And. Their increase in brightness also follows a pattern, and seems to be due to some unknown amplification effect.

This picture, in Xiao Yu's view, is like two invisible things, approaching each other. On one side is Taihao, who can block the starlight, and on the other hand, there is a sweeper who can enhance the starlight.

Finally, the two met in the center of the open cluster.

Because the distance is too far, Xiao Yu can only observe this war from a macro level. Xiao Yu saw that the dozens of stars in the center of the battlefield had fallen into an extremely unstable state. Their luminosity is moving at an eerie rate. It is constantly increasing and decreasing, and sometimes the luminosity is even thousands to tens of thousands of times higher than usual. At their brightest, they are brighter than the Moon as seen from Earth, and at their darkest, they are completely invisible.

In order to watch the process of this war more haode. Xiao Yu deliberately slowed down his fleet and moved at a relatively slow pace. So. Xiao Yu will be able to receive these signals more quickly.

Ten years after the start of the war. Xiao Yu saw that the luminosity of a star had increased hundreds of thousands of times in an instant. This is the largest increase since the beginning of the war. Moreover, its shape. It is no longer a point, but slowly becomes an irregular plane shape.

"Did the star explode......" Xiao Yu thought silently, and in his heart, he couldn't help but think of Tianyuan Si, which was destroyed at the hands of the Guardian Alliance.

This star suffered the same fate as the Celestial Yuan IV. If in accordance with the normal life cycle. It was going to turn into a white dwarf, but because of this unwarranted disaster, it had no choice but to explode and not even leave its body.

This abnormal supernova explosion is not enough to form a neutron star or a black hole. This is an explosion in the true sense of the word, an explosion of broken bones. Under the influence of this explosion, it will completely throw the entire mass that makes up itself into interstellar space.

In the midst of this stellar wreckage, the great war continues. Xiao Yu didn't know their specific means of warfare, but through the impact of this war on the surrounding space, Xiao Yu could infer the intensity of this war.

"They seem to be evenly matched, and no one can help anyone." Xiao Yu speculated.

"It seems that the Sweeper civilization also has relevant four-dimensional space technology, otherwise, according to common sense, even a neutron battle star will be unable to resist in the face of an attack one dimension higher than itself. The Sweeper civilization is worthy of suppressing the super civilization of the Guardian Alliance for tens of millions of years. ”

Through this scene of war, Xiao Yu also made a little speculation about the ethereal seventh-level civilization above the sixth-level civilization.

"First of all, it is certain that the Sweeper civilization has not stepped into the realm of a seventh-level civilization, and the Neutron Warstar should be the product of their adventures. Through the performance of Taihao and the Sweeper civilization, it seems that the key point to break through the seventh-level civilization lies in the word 'space'. However, the other Taihao civilization that imprisoned the earth girl seemed to choose the direction of soul breakthrough, not space. Does this mean that after reaching the peak of the sixth-level civilization, one must choose a main direction of attack in order to break through to the seventh-level? Or space, or energy, or time, or soul...... This classification is also likely to be the basis for the division of various different types of Taihao civilizations, such as Type C Taihao civilization, such as Type D Taihao civilization. ”

While guessing in his heart, Xiao Yu closely analyzed the distant pictures from hundreds of light years away.

These pictures have been relayed by Xiao Yu to the Eternal Realm in real time, for the more than 2,000 Lucca scientists to study at the same time.

The evenly matched war scene lasted for another decade. Ten years later, Xiao Yu saw that from the direction of the Sweeper's civilization, an unknown object suddenly appeared.

The appearance of this object caused chaos throughout the open star cluster. Xiao Yu saw that the stars that were originally moving according to their own orbits suddenly became chaotic at this moment.

"Is there a strong gravitational pull?" Xiao Yu guessed, "Then, this thing should be the neutron battle star of the Sweeper civilization." ”

Neutron stars are also divided into several different types, there are ordinary neutron stars, if it can emit strong radiation, it is a pulsar, and if it has a strong magnetic force, then it is a magnetar. Magnetars, or pulsars, are both types of neutron stars.

Neutron stars are actually invisible, like black holes. The difference is that black holes are invisible because they can bind light, while neutron stars are invisible because they do not emit visible light.

The surface temperature of a neutron star is too high, and according to the principle of black-body radiation, after the temperature is high to a certain extent, the radiation emitted by the object will be mainly emitted in the form of X-rays, so in the visible light band, Xiao Yu cannot see this neutron battle star.

In contrast to the quietness of the visible light band, X-ray radiation is extremely intense. The radiation intensity of this neutron battle star has completely suppressed the entire open star cluster that spans more than 100 light-years.

With the appearance of this neutron battle star, from the macro level, Xiao Yu saw that the darkness representing Taihao began to be suppressed by the light representing the civilization of the sweepers. The dark area belonging to the Taihao civilization is getting smaller and smaller.

"It should be during this time that Taihao sent out a space broadcast to summon the Guardian Alliance to come to the battle. The Guardian Alliance summoned more than 500 level 4 and above civilizations to come together, and finally turned this war into a huge war that could affect the entire galaxy. ”

Sure enough, the development of things did not surprise Xiao Yu. After another period of time, Xiao Yu saw that countless stars began to converge towards this open star cluster. Xiao Yu knew that every point of light could represent a huge and powerful fleet, and each fleet could contain tens of thousands or even millions of spaceships. It's just that because of the distance, the light emitted by the engines of these spaceships converges into a point, and in Xiao Yu's opinion, it is like a faint starlight.

The fleet, which represents all the high-end combat power of the galaxy except for the Sweeper civilization, has brought an extremely obvious impact as soon as it joins the war. Xiao Yu saw that at this moment, it seemed that even the Neutron Battle Star had to temporarily avoid the edge, and the black area representing the Taihao civilization suddenly expanded at this moment, and even faintly suppressed the Sweeper Alliance.

But the good times didn't last long. Xiao Yu saw that after the war lasted for several more years, Neutron Battlestar and Taihao had a head-on collision. At this moment, the neutron battle star disappeared from Xiao Yu's observation instrument, and it was completely invisible whether it was visible light or X-ray.

"The Neutron Battle Star should have entered Taihao's body. The time has come to decide the ultimate fate of this war. Xiao Yu thought.

Of course, Xiao Yu already knew the final result. But witnessing this fierce war, Xiao Yu couldn't help but get excited in his heart.

"The inside of Taihao's body is a semi-four-dimensional structure, and I don't know what the fighting method of the neutron battle star is in such an environment." Xiao Yu silently guessed, imagining that magnificent scene.

The neutron battle star was taken into Taihao's body, and he started a fierce battle with Taihao in an invisible place. Outside, the huge fleets of hundreds of civilizations are engaged in fierce battles with the regular combat power of the Sweeper civilizations. In this war, Xiao Yu saw that at least more than 80 stars suffered from the disaster of pond fish, and they had no choice but to explode and disintegrate.

The fierce war lasted for more than 30 years. The neutron battle star has also disappeared for more than 30 years, representing the black area of Taihao, which has also been quiet for more than 30 years.

Finally, more than 30 years later, Xiao Yu once again observed the intense X-ray radiation representing the neutron battle star. At the same time that the neutron battle star appeared again, Xiao Yu saw that the black area representing Taihao was violently cracked into countless pieces, and the pieces were scattered.
