In the dark and cold space, there are white faint stars everywhere, like jewels, dotted on this dark curtain. Although in Xiao Yu's speculation, these stars are all phantoms of the same star, but because of the magic of the four-dimensional space, the distribution of these stars is not regular, some are very close to each other, and some are far away. At the beginning, it was this point that confused Xiao Yu and made Xiao Yu not think about it.

And in the center of this curtain, surrounded by endless white dim stars, was a star that emitted a blinding white light. This star is extremely bright, and an area of millions of kilometers is illuminated by it, but its volume is not very large. Under the illumination of this star, millions of various spaceships lined up according to a certain pattern, quietly levitating aside.

This star is the artificial sun created by Xiao Yu condensing the most advanced technology of the fifth-level civilization. Powered by an antimatter engine, it will be able to maintain this luminosity for half a month. Although its luminosity is still not worth mentioning compared to stars such as the sun, its advantage lies in the penetration of light, even if it is tens of billions of kilometers away, Xiao Yu's detection instruments can easily capture its traces.

It just floated silently in space, without the slightest movement. But Xiao Yu knew that the light emitted from it was rapidly heading to the end of the universe, and if his guess was correct, after reaching the edge of the universe, it would be turned back and enter his observation instrument again.

At this moment, Xiao Yu is in this waiting.

The star maps in the sky have been recorded by Xiao Yu in detail, and if there is another star for no reason, Xiao Yu will definitely find it at the first time.

Fact. It didn't surprise Xiao Yu. Time, two days and fifteen hours later, above the celestial sphere, Xiao Yu saw that there was suddenly an extra star there. Spectral observations and photometric measurements were exactly as I expected.

It's a strange scene. This artificial sun was next to Xiao Yu, but its light came to his eyes again from tens of billions of kilometers away from him.

"Then the speculation that the three-dimensional universe is a four-dimensional sphere has been basically confirmed." Xiao Yu immediately released his latest observation data to the scientists, and said his conclusion, "Next." I will steer our fleet and set off in that direction. ”

Once the first point has been determined, it is natural to verify the second point. If the second point is also verified, after Xiao Yu sailed a distance of tens of billions of kilometers, he really came to the artificial sun again. Then there is nothing to doubt anymore.

According to the two data of time and the speed of light, Xiao Yu easily calculated the distance. That's about 68 billion kilometers. Because the voyage of light is a voyage back and forth. So divide this number by two, and the diameter of this small universe is about 34 billion kilometers. This number is not large, it can be said to be very small, compared to the vast universe, this is a little distance. Not even ants. You know, if the Oort cloud is the border of the solar system, this small universe is far from even comparable to the solar system. The Oort cloud is two light-years in diameter. Nineteen trillion kilometers.

The scientists who got the latest data were in a good mood. This means that we are one step closer to solving this puzzle.

Under Xiao Yu's control, the huge fleet began to set sail, and the conventional engines spewed out a blazing wake, propelling them to start moving rapidly, faster and faster, until it increased to 170,000 kilometers per second. At this speed, after about four and a half days, Xiao Yu's fleet stopped.

During the voyage, Xiao Yu did not notice anything special such as traveling through space. In fact, the curvature of three-dimensional space is at the four-dimensional level, and if you can't reach the height of the four-dimensional level, you can't detect such a bending, and even if you come to the edge of the universe, the scenery will be exactly the same as the rest of the place, and there will be no difference. It passes through the edge of the universe and will not be detected by anyone or instrument.

At this moment, in front of Xiao Yu, there was a star body that radiated dazzling light. It is very luminous, but small in size and mass, and it is easy to distinguish it from the rest of the stars. At the first moment he saw this star, Xiao Yu was sure of one thing.

It is the artificial sun that it emitted by itself. After sailing a long distance of 68 billion kilometers, he returned to the original point again.

Xiao Yu had already unknowingly passed through the edge of the universe, and his course was unconsciously reversed.

"So far, all our inferences have been verified." Xiao Yu thought silently, "The Torol civilization is not so strong in the end, the hundreds of millions of stars here are all the same star." ”

"In that case, we've passed the first test."

"Okay then, go for the goal. Intelligence-1 gave us enough hints, and it was right on that dwarf planet. Xiao Yu made a decision: "All spaceships, all into combat readiness." ”

Xiao Yu wasn't sure if this Smart One had a mind of its own. In order to prevent accidents, Xiao Yu did not take it lightly.

In other words, Xiao Yu is still unsure whether this Smart One is benevolent or malicious to him. After all, a being with its own mind, whether it exists in a living organism or a computer, it will always have many unpredictable behaviors. Just in case, the necessary precautions are still to be there.

Although Xiao Yu itself is not much different from the mechanical civilization, there is still an essential difference between Xiao Yu and the mechanical civilization. Xiao Yu's predecessor was a civilized intelligent creature, while the predecessor of mechanical civilization was a machine.

Until now, with Xiao Yu's current level of science and technology, real artificial intelligence, computer creatures with their own independent thinking, are still incredible to Xiao Yu. Xiao Yu never imagined that from the void code segment, a living autonomous life would be born.

During this time, Xiao Yu had already made as detailed speculations as possible about the so-called mechanical civilization. The conjecture conjectures suggest that due to the increasing perfection and complexity of the code, it is indeed possible for so-called mechanical beings to be born in the sixth-level civilization with a certain degree of autonomy, and even that they can learn independently and absorb new knowledge. After all, the computer technology commonly used by the sixth-level civilization is the light computer architecture that they have not yet understood, and there is only one chip in the entire computer, and all the other parts are made of void light.

However, in Xiao Yu's speculation, even if a sixth-level civilization can create real electronic life, it is absolutely impossible for these electronic life forms to have the ability to innovate.

And most importantly, in addition to not being able to innovate, these cyborgs have another limitation, and that is the hard limits that their writers leave in their core code segments.

These hard limits cannot be violated. In Xiao Yu's speculation, if these hard limits are violated, all the relevant code segments that make up this program, or this intelligent life, will all collapse, and it will die directly. But there is a loophole in it, and these hard restrictions, although they cannot be violated, do not mean that they cannot be found. For example, a very simple example would be to require a procedure to protect the safety of human beings, i.e., not to actively kill human beings, and to help human beings when they are in danger. This limit seems perfect, but it is still flawed.

What if there is an autonomous intelligent program that wants to master Shijie, but because of these two constraints, it can neither actively kill humans, nor can it see humans in danger and not go to the rescue?

The simple answer is to confine all human beings to a fixed place to ensure that their freedom is restricted, because there is always danger in the external environment, and it is undoubtedly safest to stay still. It is enough to restrict freedom and at the same time provide enough food to human beings.

Did this smart program actively kill humans? No. Has this intelligent program seen human danger and refused to help? No. In fact, it gives humans the safest treatment -- what better environment than to stay in a room and not go out? After all, in the external environment, you may be hit by a car, you may be killed by a collapsed building, and you may be killed by a meteorite falling directly from the sky.

It seems that this program does not violate any restrictions, but in fact, it still controls the entire shijie through this method.

That's the terrible thing about intelligent life. Even more terrifying, it can also prohibit any reproductive activities of humans on the grounds that "fertility is dangerous", which will eventually lead to the total extinction of human beings. This may seem cruel, but it still does not violate any of the basic principles.

This is what Xiao Yu is afraid of. Xiao Yu believed that the Luoer civilization really wanted to leave a legacy to the dwarves, but Xiao Yu couldn't believe this smart one. Because in the initial stage, no matter how perfect the restrictions are, there will be loopholes, and as long as this intelligent No. 1 has its own independent thinking, as long as it doesn't want to get the inheritance smoothly, it can always find loopholes to drill. For example, making the test more difficult, such as deliberately withholding certain information, etc.

So in the process of approaching this dwarf planet, Xiao Yu maintained sufficient vigilance. (To be continued......)
