Leaving the Shenzhou civilization is equivalent to abandoning all the previous foundations, which means that everything except scientific and technological knowledge has to start all over again. And reconstruction is not something that can be done overnight, or even in a hundred years.

The current Xiao Yu only barely has the ability to build continent-level spaceships. The New Asia spaceship was built by Xiao Yu in 50 years after sacrificing many of the rest of the construction of the project.

The reason for this is not that Xiao Yu's computing power is not enough - in fact, since coming to Titan, Xiao Yu's computing power usage rate has not exceeded 10% at its peak. The main reason is that Xiao Yu's industrial base is too weak, the number of machinery and equipment that can be used is too small, and it is difficult to explode in a short period of time, which leads to the phenomenon that Xiao Yu has no computing power but no machinery and equipment that can be manipulated.

The previous construction capacity of the Shenzhou civilization was gradually accumulated and developed in the development of nearly 100,000 years, and each step of development had a solid industrial and theoretical and planning foundation, and it was very difficult to reproduce this entire development process in a short period of time. This is not something that can be done in a short period of time.

Now, Xiao Yu's development time is only two hundred years, and in these two hundred years, he has developed from a second-level civilization to a sixth-level civilization level of construction power, which is already a very remarkable achievement. And to restore the construction capacity of the Shenzhou civilization, Xiao Yu estimates that it will take at least three thousand years to do it. As for the construction of stellar-class warships, it will be fifteen hundred years from now.

Think about it, with the industrial base and industrial accumulation of the Shenzhou civilization, it will take a thousand years to build a stellar-class battleship, and the current Xiao Yu's industrial strength is not a little worse than that of the Shenzhou civilization, and the stellar-class battleship is not even a little bit worse. For Xiao Yu now. Continent-class ships are already the limit.

Now Xiao Yu has a total of more than 30,000 warships of various types. In this fleet, there is only one continent-class spaceship, the New Asia spaceship, Xiao Yu's flagship. There are 10 national spacecraft and 200 provincial spacecraft. At this moment, except for the Asia spacecraft sitting in the solar system, most of the other spacecraft have embarked on a long voyage. Under Xiao Yu's command, these spaceships carried a large number of mechanical equipment, and each of them sailed a distance of half a light year from the solar system. He then releases a large amount of equipment he is carrying, and then moves on to the next location to release another batch of instruments.

What Xiao Yu wants to cut is a spherical space with a diameter of one light year centered on the sun. The battleship controlled by Xiao Yu was moving on the surface of this big ball. Xiao Yu selected tens of millions of key space nodes. On top of these space nodes, each node must be equipped with a corresponding space cutting equipment.

After the New Asia spacecraft was built. Xiao Yu's industrial facilities were all invested in the construction of space cutting equipment. Under Xiao Yu's full strength. The construction of tens of millions of space cutting equipment only took Xiao Yu more than ten years. It took Xiao Yu another three years to install these equipment, one year to debug and test, and after a total of 20 years, all the preparations have been made.

At this moment, in the invisible depths of the universe, there are already tens of millions of space cutting instruments distributed there according to certain laws. Together, these instruments form a sphere. The entire solar system is encased in it.

The commissioning and testing have ended, and the over-distance communication equipment has been installed on these devices, and Xiao Yu has maintained communication without delay at all times. As long as Xiao Yu gives an order, tens of millions of space instruments will be activated at the same time. Cut out space, including the solar system.

"The solar system is my homeland, and I can't tolerate such a thing as the sun being destroyed. The destruction of Tianyuan IV was enough to make me feel guilty, and such a thing could not happen again under any circumstances. Xiao Yu muttered to himself, "My two lives were given to me by the sun, and she is more important than my life." I swear that even if I die, I will not allow anyone to destroy the sun. ”

"So, let's do it." Xiao Yu silently gave an order.

A command was sent from the main control computer of the spacecraft and simultaneously transmitted to tens of thousands of instruments distributed within a light-year diameter in the form of over-distance communication. With the command given, these instruments are in action at the same time.

Half a light-year away from the Sun is a void. There is basically no matter here, it is not in the Kuiper Belt, nor is it part of the Oort Cloud, which is a vacuum within the Solar Empire's sphere of influence. In the midst of this place, there is something that clearly bears the marks of the creation of intelligent beings. It has an irregularly shaped appearance, with a length of several hundred meters at the longest point and more than 30 meters at the widest point. There's something like an antenna that extends out of it, and there's something like an indicator on top of it that's flashing constantly.

The Elemental Decay and Antimatter Hybrid Engine provides it with ample power, and within it, a series of precision instruments of the Level 6 civilization are in operation. With a command in the distance, in an instant, it was activated, and the instruments based on space technology began to operate, and the energy was so compressed that it could interact with space. It is in such a mechanism that the space is cut open.

If it is just an instrument, then it will only cause a spatial rift at most, no matter how powerful the spatial rift is, it is insignificant compared to the large universe, and it is only a matter of time before it is eliminated invisibly by the self-healing ability of the large universe. But now the situation is different. Around it, above and below it, on its left and right, at almost equal distances, there was another identical space-cutting instrument. Tens of millions of space-cutting instruments were launched together, and at this moment, a small universe including the solar system had been cut out.

Before cutting the small universe, Xiao Yu had accurately calculated the four-dimensional momentum of the entire small universe and made countermeasures in advance. After the small universe was cut out, under Xiao Yu's other order, the instruments left inside the small universe began to operate, and the traction spacecraft reserved outside the small universe also began to start at the same time. As a result, this small universe is like a kite that has been put into the sky, and there is a line between it and the ground that pulls it and controls it from flying away.

The small universe has been successfully pulled, but Xiao Yu, who is in the solar system, has not seen any change in the sky through optical equipment. It also takes time for light to propagate, and the light from the rest of the stars and the starry sky can still continue to travel for half a light-year, that is, after half a year, the cosmic starry sky in the small universe will instantly dim, and all the stars will disappear at the same time. Then it will be replaced by the sun's rays that will be folded back, and the sun's figure will fill the entire starry sky of the small universe with the passage of time.

The entire solar system has disappeared from the universe. A small universe with a diameter of one light year has been cut out, and correspondingly, a huge black hole with a diameter of one light year has been left in the large universe. Under the healing power of the great universe, it is rapidly shrinking. It is estimated that it will only take a maximum of an hour for it to disappear. At that time, the distance between two things on both sides of this black hole, which were originally one light-year apart, will be greatly reduced due to the movement of space.

In fact, Xiao Yu didn't know what the black hole-like void left behind after cutting the space was, although Xiao Yu was already quite familiar with this kind of black hole. Xiao Yu once tried to launch a detection device into this black hole-like object, but any device launched into this black hole eventually lost contact with Xiao Yu. Even Xiao Yu once launched a provincial-level spaceship equipped with a complete sixth-level civilization level shield into this kind of black hole, but this provincial-level spaceship also lost contact with Xiao Yu.

Xiao Yu has conducted a series of analyses on this kind of black hole from the spatial level, but there is no definite conclusion, the only thing that is certain is that this kind of space black hole has some similarity with the material black hole in the universe.

"Maybe it's technology in the seventh-level civilization category, no, it could be the technology in the eighth-level civilization category. Through this kind of space black hole, it may be possible to develop some kind of stargate-like technology. ”

Of course, Xiao Yu knew that these things were just his own guesses, how they would develop in the future, as an intelligent creature in the sixth-level civilization category, Xiao Yu really had no way to determine these things.

The matters related to the small universe have been completed, and Xiao Yu began to manipulate the towing spacecraft to tow the small universe slowly. At this moment, there is only one star in the small universe, the sun, and Xiao Yu can't use the sun as fuel. The rest of the fleets that carry stars have already departed, and this small universe will soon become crowded.

Thirty years later, there are more than 100 stars in this small universe. In the past few decades, Xiao Yu has been carrying out the construction of basic industrial facilities. It's just that this is a long-term thing, and it will take a long time to restore the industrial capacity of the peak of the Shenzhou civilization.

"Leave the Milky Way, continue to collect stars along the way, expand the size of the small universe, and when you reach the edge of the Milky Way, it is estimated that you will be able to collect enough stars as fuel." Xiao Yu thought silently, manipulated the towing spaceship, and embarked on the road out of the galaxy. (To be continued......)
