Since the initial data is not yet complete, Xiao Yu still doesn't know how much matter and space he has to eject in order to reduce the speed of his small universe to zero and finally merge with the big universe. But come to think of it, this dwarf planet with a volume of about 20 billion cubic kilometers should be enough.

Under Xiao Yu's manipulation, billions of engineering robots were put on this dwarf planet, working day and night. This number only includes humanoid engineering robots, not counting the rest of the various large machines, as well as the more than 2 million village-level spaceships that serve as transportation missions. Space 3 and Space 4 have been built, and they were transported to the vicinity of the dwarf planet by Xiao Yu along with Space 2. This will save a lot of time and greatly speed up the progress of the project.

So, in this lonely star system, such a strange scene happened. Countless robots and mechanical equipment are busy on the planet like ants, they are like biting bread, viciously tearing off the debris from the planet, these debris is quickly transported away by the spaceship, placed in the designated place, and then thrown out by the space weapon along with the space itself.

A line that is combined into a circle has the largest area, and similarly, a face, curled into a sphere, is the largest in volume. In order to project the most substances with the minimum power, Xiao Yu also carried out preliminary processing of these transported materials. The specific method is to put together a certain mass and volume of matter, place a gravity bomb in the middle of the matter, and then detonate it.

After the gravity bomb is detonated, the jumbled matter will coalesce into a similar standard sphere due to gravity. Then, before the gravity bomb effect is lost, the space weapon will tear this piece of space apart. Directly eject it.

Every time space debris is ejected, hundreds of millions, billions of tons of material are ejected, and after three months of work, the diameter of the planet has been reduced by a full 500 kilometers.

This means that it has lost a considerable amount of quality. But its kinetic energy is still there, and it is still orbiting the white dwarf at its original speed. A decrease in mass means a decrease in gravity, and gravity binds it less, so that its orbit expands outward by hundreds of thousands of kilometers.

The calculation of the orbit of the small universe has been going on. The shrinking number shows that the distance between the small universe and the large universe is constantly decreasing. Ahead is success, and Xiao Yu is moving forward step by step.

It's crazy engineering. In the more than 10,000 years since he left the earth, Xiao Yu has destroyed more than one planet. For example, it will be blown up, for example, it will be pushed directly into the star. But such a crazy way of destruction. Xiao Yu is still the first time. Moreover, Xiao Yu estimates that in the big universe, there will be no existence that will adopt this method.

What a huge and crazy thing to completely dismember a planet!

Thankfully, the planet is a dwarf planet, and there is no liquid lava inside. The extremely low temperature also made it impossible to exist in liquid water or other liquid substances, which saved Xiao Yu a lot of trouble.

During the project, Xiao Yu also took the opportunity to study the geological composition of the planet in detail and improved his theory of planetary evolution a lot.

Little by little, time passed. Everything was as Xiao Yu expected. The small universe is getting closer to the big universe, and the spatial stability of this small universe is getting lower and lower. This means an increase in the efficiency of space weapons, and up to now, a space weapon has been able to eject tens of cubic kilometers of material in a single shot.

Time has passed quietly for a year, and the appearance of this small universe has been completely changed by Xiao Yu. The fragments of the battleship that can be seen everywhere have been recovered by Xiao Yu, and the fragments with useful value have been properly kept by Xiao Yu, and those with no use value are mixed with those materials from dwarf planets and thrown out directly.

By now, the diameter of this dwarf planet has been reduced to less than 200 kilometers, and it has become a veritable asteroid. Due to its own pressure, although it is not possible to form liquid lava inside it, it is still possible to increase the temperature normally, in fact, in the process of digging by the robot, the closer it is to the core, the higher the temperature, until it has risen to nearly 300 degrees Celsius.

There is another point, also due to its own pressure, the material density of the planet's core will be very high, although it has not yet reached that exaggerated point, but the obstacles to Xiao Yu's engineering progress are still very obvious.

The working environment began to deteriorate, and the progress of the project was seriously hindered. Xiao Yu thought about it for a while, and simply didn't do anything, and directly sent special engineering robots to drill several large holes hundreds of kilometers deep on the core of the only remaining planet, buried a large-yield nuclear bomb in it, and then directly detonated it, and with a dazzling flash of light, the little material left by the planet Zuihou was also blown to pieces.

The planet finally completely disappeared in Xiao Yu's hands, and there were not even bones left.

After blowing the planet into pieces, the progress of the project went much smoother, but Xiao Yu gradually became worried. Now Xiao Yu has a large amount of shiyan data, and he can basically calculate how much matter needs to be ejected to slow down this small universe to a stationary state.

The results of the calculations seem to confirm Lucca-3's guess that in Xiao Yu's calculations, the mass of the ejection needed to make this small universe completely stationary is about the same mass as the mass of the dwarf planet.

This is basically not a coincidence, and this fact illustrates the arrangement of the Torol civilization from the side. Xiao Yu also began to believe that this dwarf planet was really left by the Torol civilization, specially for the dwarf civilizations that entered later to slow down this small universe.

But this calculation result is only approximate, Xiao Yu is not able to get too accurate data at present, that is to say, to reduce the speed of this small universe to zero, the actual mass required may be a little wrong with this, it may be more than the overall mass of this dwarf planet, and it may also be a little smaller than the overall mass of this dwarf planet.

If it's a little smaller, then there is no problem, but ...... What if you need more mass than this planet?

Don't forget, even if this result is only a 0.1 percent error - you know, the Torol civilization has left this relic for hundreds of thousands of years, and it doesn't seem unusual for a slight error of 0.1 percent to occur in these hundreds of thousands of years.

But if you do the conversion, you will find that things are not so simple.

The total mass of this dwarf planet is about 2 trillion tons, and the mass of 0.1 percent is 200 million tons. With so much quality, where is Xiao Yu going to find it?

There is no doubt that the white dwarf will have a lot of mass, but with Xiao Yu's current level of technology, he does not have the strength to do anything to a white dwarf.

In addition to this white dwarf, there are a large number of fragments of warships in this small universe, but their total mass, at most, does not exceed one billion tons, which does not play a big role.

When there are no foreign objects to borrow, Xiao Yu can only start with his own things. But one thing to know is that a national-level spacecraft only has a mass of a few hundred million tons. If there is really a 0.1% error, even if all of Xiao Yu's spaceships are used to fill this gap, it will not be enough.

"If things really develop like this, I have no choice but to cut the corpse of this fourth-level beast." Xiao Yu thought secretly, "The corpse of this fourth-level beast has a total mass that has almost reached the trillion ton level. But I'm going to use this thing to build a ship...... Hey, let's hope it doesn't come to this. ”

"Let's throw the rest of this planet out first." Xiao Yu sighed secretly, cheered up, and began to put the finishing touches on this work.

In the current small universe, the dwarf planet has completely disappeared, and its huge body is only a few asteroid fragments with a diameter of only a dozen kilometers. Xiao Yu didn't intend to let go of its corpse, and the space weapon was activated, and he quickly threw these things out.

After completely dismembering the dwarf planet and throwing it all out, Xiao Yu once again carried out a big cleaning in this small universe, and all the damaged parts, the fragments of the battleship that had no recovery value, and all the garbage were gathered together, about 300 million tons--all thrown out at one time.

Everything has been done so far. Xiao Yu began to wait quietly.

At this moment, the small universe is overlapping with the large universe. To verify whether the small universe has been offset by Xiao Yu with all the kinetic energy, there is a very simple way, that is, to see if the small universe will leave the big universe again. If you leave, it proves that the small universe still has kinetic energy, and your own things have not been done. If the small universe does not leave the big universe again, then it proves that it has succeeded, and in the next time, you only need to wait quietly, and in a month at most, the small universe will be assimilated by the big universe.

And the answer to this question is very simple, that is, it constantly emits low-power spatial cracks, and indirectly calculates through the strength of the cracks.

The space-1 on the China spacecraft was in this situation, and one after another tiny space cracks flashed in front of it and disappeared quickly...... (To be continued......)

PS: zuihou has been a day, and I'm trying to ask for a monthly pass!
