Just as three-dimensional space is relative to two-dimensional space, four-dimensional space has one point closest to three-dimensional space. For example, if there is a small ball on a two-dimensional plane, and it is one decimeter away from the white paper that represents the two-dimensional shijie, then the closest point to the three-dimensional shijie object in the two-dimensional shijie represented by the white paper is undoubtedly directly below the small ball.

Because only directly below this ball is the vertical distance between the two, and the vertical distance is the shortest distance. Any point that deviates directly below will not form a straight line perpendicular to the two-dimensional plane with the ball, and the distance between them is not the shortest distance.

From this, it can be seen that in the three-dimensional shijie, there must also be a point closest to the four-dimensional shijie object. This point, above the scale of the four-dimensional space, in the fourth dimension, this straight line, perpendicular to the three-dimensional space.

Although the three-dimensional creatures cannot concretely imagine and understand the magic of the four-dimensional space, the specific position of the object in the four-dimensional space and the closest point of the three-dimensional shijie can be deduced mathematically. In fact, this mathematical method is not complicated, and the fourth-level civilization can also easily come up with the answer.

In this way, one of the biggest prerequisites has been satisfied, that is, the dwarves of the fourth-level civilization can also find the entrance to the ruins of the Torol civilization through this method. After all, the remnants of the Torol civilization are reserved for the dwarves.

Xiao Yu only made calculations for a very short time before coming to a conclusion. During the calculation, the location of this point has been identified by Xiao Yu in the three-dimensional image.

"It's such an amazing thing." Xiao Yu felt a little emotion in his heart. Three-dimensional shijie creatures, i.e., unaware of the existence of the fourth dimension. It is impossible to make an intuitive guess about the fourth dimension, and human beings cannot clearly imagine what the fourth dimension is like imagining a cup or a table, but through the tool of mathematics, it can be expressed very clearly.

"Then it's decided." Xiao Yu said, "I will take our fleet and rush to the reservation location within the reservation interval." ”

"The host, I think. You don't really have to take the risk yourself. Just send a sapient creature as the leader, and then send some combat liliang to follow. You must understand that we are not here to fight, our purpose is only to obtain the relics of the Torol civilization. "After Xiao Yu announced the next action Jihua. One scientist suggested.

Xiao Yu only thought for a moment, then manipulated his phantom and shook his head slightly: "In this ruins." The relics of the Torol civilization are very important to me. Only if I go there in person can I have the greatest certainty of getting it. Not to mention. In my reasoning, there is only a 6 percent chance that the operation will be destroyed, in other words, a 94 percent chance that we will be safe, and it is well worth the risk. After all, it's just a relic. And not the battlefield. ”

Seeing that Xiao Yu was so resolute, the scientist stopped talking. In fact, Xiao Yu understands its mind very well. Out of consideration for the control of these intelligent civilization creatures, Xiao Yu took control of all spaceships. It's all in their own hands. As long as he dies, all intelligent and civilized creatures under his control will also die. The scientist was obviously worried about this problem, so he didn't want Xiao Yu to take the risk. After all, their lives are all tied to Xiao Yu.

But Xiao Yu has a deeper consideration. Until now, Xiao Yu could not fully trust the loyalty of these alien intelligent creatures. Under their own control, of course, the loyalty of these creatures is not to be worried, but what about being out of their control?

Who knows, after entering the so-called new shijie, these ships will still be able to be under their control? In Xiao Yu's inference, there is a high probability that over-distance communication is not suitable for four-dimensional space, then, in order to avoid this problem, Xiao Yu needs to authorize them to complete control of the spaceship, and then they enter the ruins, if they are really lucky enough, get the weapon called Split Space, and then manipulate the spaceship out of the ruins again, relying on this weapon to deal with themselves?

The huge difference between the civilization levels made Xiao Yu not sure that he could rely on his current strength to fight against a spaceship equipped with a sixth-level civilization weapon, even if there was only one such spaceship.

So Xiao Yu chose to take a risk in person.

There are other benefits to choosing this way. Xiao Yu, who has a huge computing power, is always much stronger than the rest of the intelligent creatures, and he has the greatest chance of successfully obtaining these relics of the Torol civilization by going there himself. After considering all these considerations, Xiao Yu chose to go there himself.

"So be it, I'll lead all the ships to the predetermined location in three days, and if I can, all of them will enter the ruins." Xiao Yu announced his decision.

The expressions of the scientists who heard Xiao Yu's decision were different, some were calm, some were worried, and some were excited. Xiao Yu looked at these different expressions, and there was no fluctuation in his heart.

All kinds of orders had been issued, and Xiao Yu's fleet quickly completed the assembly, and then rushed to the reserved place. Since this is close to the star, it is not possible to sail in curvature, so this voyage is a regular sub-light voyage.

Watching the huge star that was constantly changing its trajectory as if it was suffering from sheep epilepsy getting closer and closer, Xiao Yu's heart was calm as usual.

The arrival of a message made Xiao Yu's mood fluctuate a little, and Xiao Yu secretly thought, "This guy is still following me." ”

That's right, this message is about that fourth-level beast. The detection data showed that after Xiao Yu's huge fleet began to set off towards the predetermined target, this guy also began to move his position and continued to follow Xiao Yu loomingly.

"You've been with me for hundreds of years...... It's time for a break. Xiao Yu smiled coldly in his heart, "After getting the weapon of Split Space, I will see where else you can run." ”

Xiao Yu's current weapon system is actually not advanced compared to Xiao Yu's level of technology, at least compared to the Molian civilization. Xiao Yu believed that if he really obtained a space weapon from a sixth-level civilization, his shortcomings would be fully compensated.

"At that time, I will have four maintenance shields in defense and space weapons in attack, who else in this galaxy can pose a threat to me except for the sixth-level civilization? It's just a small fourth-level beast, not enough to worry about. ”

After a few days of regular sailing, Xiao Yu's fleet had arrived at the place where it was booked. A series of orders were issued, and the robots and the leaders of the various clans faithfully fulfilled Xiao Yu's orders, such as raising the alert level, reassuring their respective clansmen, and telling them not to panic no matter what situation they encountered.

Because in Xiao Yu and Luka II's speculation, the dwarves would be the key to open the door to the new Shijie, Xiao Yu made special arrangements for this, relaxed the concealment of the forty Homeland spaceships, and deliberately exposed them. Regardless of whether it is useful to do this, Xiao Yu believes that it is better to do it than not to do it well.

"Okay, let's start waiting." All the preparations have been completed, and the rest, whether the specific way to enter the ruins is as I speculated, can only be left to the heavens in the underworld to grasp.

Time passed bit by bit, and everything in the starry sky was as silent as ever, there were no planets, no comets, no asteroids, only the huge star, which was as bright as ever, in the face of this empty cosmic space, exuding its own heat in vain.

Xiao Yu's thoughts drifted far away.

Xiao Yu began to think about a question, a profound question, that is, what is all this for? What's the point?

This star does not emit heat, and even if it exists, it will not have any effect on the outside world, it is insignificant, it is ignored, and at the same time it is unconscious, so what is it for?

Not only this star, but there are many such things in the universe. It doesn't matter if they exist or not, but they do exist. Xiao Yu couldn't understand that all of this existed because of Weishenme.

Perhaps existence itself is a meaning? Or is there really an all-knowing and all-powerful God in the universe who controls all of this in secret?

This question has already begun to be thought about by humans in the Earth Era, but it was not until he became a fifth-level civilization that Xiao Yu still did not come up with an answer to this question.

"The universe is vast, and there are so many secrets hidden in it, whether it is in natural sciences or humanities and philosophy, there are many questions waiting for me to explore. Perhaps, the meaning of the existence of intelligent beings is here, in the continuous exploration, solve one unknown after another, at the same time, contact more unknowns, and then start a new round of exploration until the end of life. But my existence is not limited by time, if nothing else, I will have an infinite lifespan, so where is the meaning of my existence? ”

A sudden message interrupted Xiao Yu's thoughts and brought Xiao Yu back to his senses.

"My people, welcome to Shijie in Torol."

In the midst of the silent waiting, the ruins of the constantly changing position crept in. At the moment of arriving at the scheduled time, Xiao Yu's brain received such a message. (To be continued......)
