Xiao Yu already knew what kind of mechanism was to prevent him from leaving, but Xiao Yu didn't know the principle of this mechanism, the reason for it, and how to crack it.

"Maybe it's really because the spatial structure has been changed." Xiao Yu thought silently, "Only when the space-time structure is changed can a battleship be reversed immediately without the need for time." The reason why I didn't observe spatial abnormalities before may be that my observations are not accurate enough. As long as I understand this space-time structure, there will be no obstacle for me to get out of here. ”

If this is really due to the change of the structure of time and space, then its principle will be no different from the space labyrinth technology that Xiao Yu has mastered, it is nothing more than a high-tech content and a low-tech content, and their basic principles are the same. According to Xiao Yu's familiarity with the space maze technology, after detecting the distorted space-time structure clearly, Xiao Yu will feel like looking at the map to break through the maze without any difficulty.

Xiao Yu sent a huge scientific research fleet with a large number of observation instruments and set off, while the main fleet remained in place as an observer, so as to facilitate his access to two sources of information at the same time. The spacecraft, carrying ultra-precision space observation instruments, came to a certain point and then stopped.

This point is a point that Xiao Yu has accurately observed after hundreds of thousands of failures. At this point, the mechanism similar to the reversal of time and space will not be triggered, and once this point is crossed, that mechanism will be triggered immediately, and Xiao Yu's fleet will be completely flipped over. This point is that tipping point.

Just above the tipping point. The sophisticated observation instruments carried by this fleet began to observe the current space. Xiao Yu first carefully measured the impact of the existence of quasars here, and then completely eliminated this influence through data calculation, restoring the original space that was closest to the real situation now. Then, he carried out an in-depth analysis of this original space, trying to find clues that the spatial structure had been changed in this space.

But the final result disappointed Xiao Yu. Under the observation of Xiao Yu's most accurate and sophisticated instruments, Xiao Yu did not find any abnormalities in the spatial structure here.

"So...... Does this mean that it wasn't the structure of the space that prevented me from leaving? Xiao Yu muttered to himself, giving up his plan to find a flaw in the spatial structure. The reason is very simple, Xiao Yu has already tried his best and still can't find a flaw in this regard, which means that even if it is really because of the spatial structure, he can't leave. With his current level of technology, he can't find a breakthrough here. It is better to give up wasting time in this area altogether and look for other aspects, and maybe you can find a breakthrough.

Time passes little by little. After an unsuccessful attempt to find a breakthrough in spatial structure, Xiao Yu began to try another approach.

After Xiao Yu's on-the-spot exploration, near this quasar, no matter which direction he tried to leave here. After advancing to a certain distance. will encounter a reversal of direction, and then leave to become close to this situation. This suggests that what stands in the way is a spherical structure that completely envelops the quasar. However, this spherical structure has a special property that does not prevent things from the outside from entering its interior, just as matter from the companion galaxy can enter it unhindered, and it does not prevent natural objects such as light and stones from leaving it. It seems that the only thing that is hindered is the craft and the artifacts that he has built.

Then a question arises. The question is simple, why rocks and light. Something like radiant energy can get out of here, but your own battleship can't? What is the essential difference between one's own warship and these stones?

Xiao Yu tried to completely destroy a spaceship, turning it into a pile of broken copper and iron, and then gave it a certain initial acceleration to see if it could break through the limits here.

Not far from the tipping point, the curvature-navigating spacecraft released the pile of scraps, and the conventional accelerator propelled the pile of debris forward for a while, accelerating it to a speed of ten kilometers per second, and then the accelerator automatically detached from it. So, in the starry sky of the universe, this pile of waste flew straight towards the location of the barrier.

Xiao Yu's spacecraft made a close observation of the place. In Xiao Yu's line of sight, this pile of ruins slowly approached the place where the ruins existed in the observation, but in the next moment, its direction was reversed. It is still moving at a rate of 10 kilometers per second, and it seems that its inertia has not been affected in the slightest.

Xiao Yu's attempt failed again.

"Is it forbidden for any unnatural creature to leave here?" Xiao Yu thought about it quite unwillingly, and a new idea popped up.

Xiao Yu captured a meteorite that came quickly, according to its atomic and molecular structure, using the material on his spaceship, using his own advanced technology to create a stone that was exactly the same as this meteorite, and then threw the stone over again, wanting to see if this stone could leave here.

If this stone is said to be a natural creation, it is made by Xiao Yu through extremely advanced technology, and if it is said to be a scientific creation, it has exactly the same structure as a natural creation. It can be regarded as a contradiction, and to Xiao Yu's surprise, such a contradiction has successfully passed through the barrier here and entered the outer cosmic space.

Xiao Yu sighed a little helplessly-even if it was an artificial creation, he could leave here, but could he really forge all his spaceships into stone? If you are all forged into stone, how can you survive?

This experiment was considered a success, but it was meaningless to succeed, and Xiao Yu still had no clue about how to get out of here.

Xiao Yu once again started a new attempt. This time, Xiao Yu tried to use the method of leaving the semi-four-dimensional Taihao to create a barrier for himself, Xiao Yu tried to create a Klein bottle, or a four-dimensional creation that can only be fully displayed in the five-dimensional space, the Luoya Cup, but without exception, the unification failed.

Xiao Yu was not discouraged, and after a little thought, Xiao Yu made a new attempt......

Just before the most violent celestial body in this universe, Xiao Yu tried again and again. There were many times when a new idea came up, Xiao Yu was overjoyed, thinking that he had definitely found a way to succeed, but unfortunately, the final result was all failure.

Failure, failure, or failure.

"What the hell is going on?" Xiao Yu thought a little desperately, "Could it be that I really have to be trapped here and never be able to leave?" I've tried everything I can think of, everything I can do with my technology...... I have synthesized the technology of the four civilizations of micro-civilization, computing civilization, architectural civilization, and space civilization, and I still can't solve the problem here, who created such a barrier? ”

In the process of Xiao Yu's continuous attempts, nearly ten years have passed. Xiao Yu even tried to use a super giant chain reaction space bomb, but it was still useless except to make this space more and more violent.

"Whether it's logical, or theoretical, or physical, I should be able to get out of here, but why, I just can't leave? Why am I still stuck here? ”

There is simply no way to explain this situation. Even, after being busy for so long, Xiao Yu didn't even know what it was and what was stopping him from leaving.

Xiao Yu's fleet stopped at the critical point, looking at the starry sky outside without any abnormalities, in a daze. There doesn't seem to be anything abnormal here, but Xiao Yu knows that as long as he moves forward a little more, his direction will be reversed, and he will once again change from the quasar of the principle to the quasar close to this quasar. This scene has been repeated here a million times.

Xiao Yu has no way anymore, because all the conceivable methods, no matter how ridiculous Xiao Yu has tried. But Xiao Yu still had no intention of giving up. After so many years in this universe, no matter how difficult and dangerous things Xiao Yu has encountered, the current situation, no matter how dangerous it is, it is dangerous, but he will die immediately, right?

Shaking his head slightly in his heart, Xiao Yu calmed down, started a new round of calculations and research, and began to continue to look for the next way.

But at this time, a burst of ethereal "music" was felt by Xiao Yu. It doesn't seem right to say that it's music, it's just a message, but it gives Xiao Yu a feeling of music. Moreover, Xiao Yu can analyze the information from this "music" very smoothly.

"There lived a strange boy near my house, his hair was getting longer and shorter, he cut off his arm and found that it was still on top of his body, he was full of food but his stomach was still hungry, he turned on the light and the room was still dark, oh, there lived a strange boy near my house, I wonder why everything in the world is reversed in you, weird boy, weird boy ......" (to be continued......)
