In the small universe, the solar system, and on Mars, Xiao Yu and Zhang Shengya are still sitting side by side on the high mountains. In the dark sky, the vast war scene still continues.

But Xiao Yu knew that the night was not peaceful at the moment. At the foot of Xiao Yu, in the midst of this huge mountain, a huge construction operation is underway. Endless amounts of equipment and supplies are being transported to the hollowed-out peaks and quickly installed. In order to speed up the progress of the project, Xiao Yu even used weapon-grade equipment. This huge construction has begun since the emergence of microscopic civilization. By now, it has lasted more than two hours.

Xiao Yu's huge construction ability is fully displayed here. However, no matter how large the scale of the construction carried out in the shadows, there is still no trace of it from the outside. The beasts were still asleep in their places, and the unknown insects were still squeaking. The stars are dotted, and the night is as cool as water.

This is the last time to be together, and then they will be separated, and the two may be separated by hundreds of millions of light years from each other, and they may never see each other again. Xiao Yu didn't want to spoil the atmosphere here. But these construction actions are also necessary just in case. Therefore, Xiao Yu can only choose this hidden form of construction.

At this moment, in the space laboratory, the neutron battle star is still spinning at high speed. Its size has increased significantly, so its rotation speed is constantly decreasing. However, if you calculate the distance traveled by a point on the equator line in a certain amount of time, its rotation speed does not actually slow down.

Circle after circle, the spatial fluctuations spread out like water ripples. Each circle of space ripples represents at least tens of billions or hundreds of billions of tons of mass that have been converted into space.

Xiao Yu knew that from this moment on, the Neutron Battle Star had been irreversibly damaged. This kind of damage is impossible to repair with at least the technology of a sixth-level civilization. The damage was deepening, half an hour later. It will completely destroy the Neutron Warstar.

If a neutron star keeps losing mass, what will it end up becoming? According to common sense, it seems that it should become a white dwarf. But that's not the case. After the mass of the neutron star is reduced to a certain limit, its own gravitational pull will not be enough to maintain such a tight structure, and it will expand catastrophically. In the process of expansion, this momentary explosive force will exceed the limit of a star's ability to maintain its own balance, so it will explode to pieces, and it has no chance of becoming a white dwarf star gently.

The same question, what does a white dwarf become when it keeps increasing its mass? According to common sense. It seems to turn into a neutron star. However, this is only under ideal conditions, and it is unlikely that such a thing will happen in the real cosmic starry sky. When the mass of a white dwarf has gathered to a certain extent, the extreme environment can trigger an uncontrolled nuclear fusion reaction, and a nova explosion will occur. And when the mass of the white dwarf accumulates to the Chandrasekhar limit, it is about to reach the critical mass of the neutron star. It also can't become a neutron star smoothly. It will have another type of more violent explosion - a Type Ia supernova explosion, which will eventually blow itself to pieces.

White dwarfs slowly become neutron stars. Or something that a neutron star slowly becomes a white dwarf. It only exists in theory. Xiao Yu had never observed such a thing in the real cosmic starry sky.

It is clear that if the current situation continues, then the fate of the Neutron Battlestar will also be like this. It will explode violently, releasing an explosion of energy no less than a supernova explosion, completely destroying the space laboratory as well as completely destroying itself - the space laboratory is a disposable.

The fierce battle with micro-civilizations continues. However, from the current point of view, the microscopic civilization has no chance to achieve its goals. They may be victorious, but the destruction of the Neutron Battlestar is already doomed.

Xiao Yu made up his mind from the beginning. Since the Neutron Battlestar cannot be its own, then it must be destroyed. The Sweeper's civilization has too much grudge against himself. So the Sweeper civilization must be exterminated. No amount of quid pro quo will change that. Unless the person who comes has the ability to threaten his own life.

When defeating the Guardian Civilization, the Micro Civilization has the ability to threaten his own life, so Xiao Yu chooses to compromise. At present, the microscopic civilization no longer has the ability to threaten his life, so Xiao Yu chooses to persevere to the end.

"Xiao Yu, stop. We can promise you a tenfold increase in the value of the chips that are ready to be exchanged. You can get detailed star maps within 10 million light-years, learn the secrets of different types of civilizations, and where they are often active. We can even tell you something about an eighth-level civilization, or tell you something about the Rebel Alliance. As long as you let go of the Neutron Warstar, let go of the Sweeper civilization. You should know that even if we can't save the Neutron Battlestar, we still have the ability to keep pestering you in the future and causing you great trouble. For the sake of a sweeper civilization, it's not worth it. ”

At this time, Xiao Yu received a message from the microcosm civilization.

"No, it's worth it relative to my feelings. Because they killed my comrades, they set up and secretly calculated me for millions of years. If I don't wipe out the Sweeper civilization, I won't be able to calm down. Micro-civilization, don't talk about it anymore, it's useless to talk about it more. Let's talk by our means. Xiao Yu said lightly.

"To each his own means, right? It's good, it's good. "The microcosm sent another message, and then there was no sound. At the same time, countless microscopic civilization ships suddenly gathered together again. They flew out of the space shield, flew from different ships, flew out of the void, and finally converged into a colorful ribbon that floated gently through space.

Their movements were very fast, and they had disappeared before Xiao Yu could see them clearly. The next moment, they came to the edge of Xiao Yu's small universe. They are trying to invade Xiao Yu's small universe.

The small universe that the Sweeper civilization has spent a lot of energy and has failed to break through at a huge cost, but it seems to be just a decoration in front of the microscopic civilization. Although the small universe is a small universe, after all, it has a diameter of more than one light year, and it is still too big, and Xiao Yu has no way to completely protect it.

The moment the microscopic civilization began to invade the small universe, Xiao Yu issued an order.

"Beasts, whatever you are doing now, I command you to come to me within a minute...... There's a very strong enemy coming in, and you're in danger......"

All of a sudden, whether it was day or night, whether it was playing or sleeping, the beasts flew at the same time, like rockets, converging towards Xiao Yu at an incredible high speed, and converging at the foot of the mountain peak where Xiao Yu was.

Xiao Yu was still at the top of the mountain, and at this time Xiao Yu had already stood up and looked up at the sky. A point of light appeared in the sky, small at first, but expanding in the blink of an eye. It wasn't big, but it had an extremely bright flash, and it had a tail trailing behind it, like a meteor. It was rushing towards Zhang Shengya quickly.

"Do you want to take hostages and threaten me to let Neutron Battlestar go? How could I not have prepared in advance. Xiao Yu smiled faintly and shook his head.

The meteor rushed swiftly towards it, and as it passed through the sky, the huge image of war vanished for a moment, and then shattered like glass. It didn't stop at all, it continued to move forward at a rapid pace. It was already very close to this mountain, and even the light emanating from it had already reflected Xiao Yu and Zhang Shengya, as well as the rest of the things above the peak. But Xiao Yu didn't move.

When the distance between it and Xiao Yu was shortened to less than a hundred meters, a protective shield emitting a faint red light suddenly lit up. As if it had hit a wall, the meteor formed by the convergence of microscopic civilizations suddenly stopped. A faint ripple spread over the massive shroud.

Micro-civilizations collided for the second time, but they still came to naught. They didn't collide a third time, but suddenly they dissipated, disappearing like extinguished candles. At the same time, they dispersed into hundreds of billions of small individuals and once again plunged into the spatial shield.

"You can't break through the space lab, you can't break through the Sun spacecraft, and you can't break through this layer of protection either. Although the power and strength of the shield here are not as strong as those of the Space Laboratory and the Sun spacecraft, the area to be protected here is very small. A decrease in area means an increase in unit power. More than two hours of construction time was enough for me to finish the construction here. ”

A little ripple appeared on the space shield, and a little bit of flash. From here, the ripples and flashes of light appear as if they were above the sky. All of a sudden, the stars shone brightly, and the scene was extraordinarily magnificent.

"Aya, don't be afraid, with me, no one can hurt you." Xiao Yu said softly.

And at this time, another part of the instrument also began to be activated. Since Xiao Yu had already taken precautions against the microscopic civilization's invasion of the small universe and the hostage-taking to force him to comply, how could he not make the rest of the arrangements and make a plan to make the microscopic civilization suffer a dark loss.

"This is the second time that you have gone against me, and if you don't let anything be left, how can I just let you go." Xiao Yu thought lightly. (To be continued......)
