After the skull level, what is left is the labyrinth, in fact, this labyrinth has been explored by Xiao Xuan, Qiye and Bodhi many times, under the accumulation of experience in one reincarnation, it has been figured out, in the last reincarnation, Xiao Xuan directly followed the marks on the notebook recorded by Bodhi before his death, that is, it took a little time to pass, and did not encounter any big obstacles, nor did he encounter any danger, it can be said that it is very simple, It's the least technical of all the levels, and of course, this sentence is also based on the hard work of the previous reincarnation.

However, this time, the original simplest thing has become not simple, because Xiao Xuan, Bodhi, and Qiye actually entered according to the original route, went around, and walked out of the original entry point, which is equivalent to them going around in a circle and returning to the same place.

If you are an ordinary person, you should continue to walk again to see if you have made a mistake, if it is still the same again, it is very likely that you will come back several times, after all, you have the "correct answer" in your hand.

But Xiao Xuan didn't do this, because there were three people walking together, since he, Bodhi and the Seven Nights Monk walked together, they didn't go to the exit but went around in a circle, and returned to the entrance, which proves one point, that is, the so-called "standard answer" in his hand, it is wrong.

The labyrinth is very large, and it is condensed in space, and if you can't get around, you must go out of it, and the walls of the labyrinth are made of 10,000-year-old ice. If you want to destroy it, it's very difficult, and if you can't see the whole picture and know the layout of the maze in your heart. Even if you destroy a few walls, it won't help.

"Why is this changing?"

Bodhi is asking himself and others, this question, in fact, does not need to be asked, but since it is asked, it means to the bright side. Let's discuss and brainstorm. Facts have proved that in the face of the wisdom of Xiao Xuan, Bodhi and the Seven Nights monks, there are really not many obstacles and problems that can be stopped.

"Amitabha. The poor monk felt that our measures to break through this time were different from before, so it caused the changes in the current labyrinth, for example, in the previous many passes, when we walked here, someone should have died, or rather, we did not cross the river demon, and did not break through three levels in such a devastating way. In short, to look for different places, to find tangent points that may trigger changes in the maze. There are so many of them, and at the moment, the poor monk thinks that the problem we want to solve is how to get out of this labyrinth, not why it has changed. After the Seven Nights Monk finished speaking, Xiao Xuan and Bodhi both nodded. Expressing his approval of Nanaya's words.

"Labyrinth, what is it? It is a layered layer of space. Here, we will lose our place, lose our direction, lose the path we have taken before, and naturally lose the path we should take. But here, why are we lost? Whether it's you, the monk, the Bodhi, or me, each of us, when we reach this realm, we already have an extremely terrible perception, we can sense the breath we have left, we may not be able to predict the path we will take, but we will never forget the path we have walked. Xiao Xuan's speed of speech became faster and faster, it seemed that he had discovered something, and began to prepare to tell his confusion.

"That's right, we didn't get out this time, we didn't get lost in the maze, we actually walked in through the entrance again, which is a very important point." Bodhi said in a deep voice.

"Amitabha, in fact, this also seems to mean that the path we took before was still right, but in the middle of the way, something should have happened, so that we didn't go to the exit but walked back to the entrance again." The Seven Nights Monk stretched out his fingers and knocked on the ground, as if he was knocking on his own wooden fish, but, after a while, the Seven Nights Monk picked up a snowflake on the sole of his shoe, and his face showed a touch of contemplation, and said: "This snowflake, obviously in the degree of condensation, is different from the surrounding snowflakes, it was brought into the labyrinth by the poor monk, and brought out, it seems to be less condensed than the surrounding snowflakes for a while." ”

Hearing this, Xiao Xuan raised his head and said directly: "It's time, after we entered the labyrinth, halfway through, we were stolen of time, so we unknowingly, we walked out again the way we came." ”

"Captain, do you mean that the current labyrinth is no longer a three-dimensional space, but a four-dimensional space?" Bodhi asked with some confusion, while looking at the maze in front of him, "Is this really four-dimensional?" ”

In physics, the parameter that must change to describe a changing event is called dimension. A few parameters are just a few dimensions. For example, the position of a "door" is described only by angles, so it is one-dimensional rather than two-dimensional.

To put it simply: zero-dimension is a point, with no length, height, or quantity. One dimension is a line composed of countless points, only the length, not the width or height of it. A two-dimensional is a surface made up of countless lines, with length, width, and no height. A three-dimensional body is a body composed of countless faces, including length, height, and quantity.

Because the human eye can only see three dimensions, it is difficult to interpret more than four dimensions. Just as a person with normal intelligence and born with only one eye and one ear (so that there is no binocular effect, binaural effect), it is difficult for him to understand distance, and he is likely to think that the world is two-dimensional. To put it simply: n-dimension is the space formed by two or more n-1 dimensional objects perpendicular.

"If there is a time factor in this labyrinth, it will be much more difficult, no, it is too difficult, because our level has not yet reached the level where we can contact time." Bodhi continued.

"That's right, our level and ability can't affect time for the time being, we can only affect space, but this labyrinth is not a four-dimensional space in the real sense, but a pseudo-four-dimensional space, it can only steal our time, but can't make up for us, otherwise, we will not just return from the same way as this, but will keep repeating and playing circles in this labyrinth, and before we know it." Xiao Xuan stretched out his hand, took off his glasses and wiped them.

"Since it is not a four-dimensional space in the real sense, and it is not the influence of time in the real sense, we still have a chance." Bodhi replied, and then Bodhi shrugged his shoulders again and said, "Now, what we have to discuss should be how to get back the time we have been stolen. ”

"Amitabha, the poor monk thinks that it is difficult to get back the time that has been stolen, and the difficulty is too great, and our Chinese team is a little powerless now. However, in fact, the poor monk felt that we could change our thinking, change our approach, or simply turn it upside down. ”

"Yes, we can use the entrance as an exit and walk in backwards, and let it steal our time when the time comes." Xiao Xuan made this suggestion, and at the same time threw a notebook to Bodhi, and said: "As for how to walk backwards, you plan first, calculate the location of the node, and wait for us to be stolen from the time, to ensure that we are on the road out of the maze." Here, don't forget to consider Einstein's theory of symmetry."

For Einstein's four-dimensional space, it is generally believed that space is axisymmetric, or centrally symmetrical. For example, if a person in 3D space enters 4D space and "rotates" it in an appropriate way and then returns to 3D space, then he will be 'axisymmetric' (this is of course not possible in 3D space, unless a 3D version of the Mebius strip is used). Of course, since no one has entered the four-dimensional space, this is only an analogy from the two-dimensional space and cannot be verified. But the idea of the timeline and the phenomenon of the moment of disarray of time and space are consistent with this.

A figure from two-dimensional space cannot be symmetrical in two-dimensional space, but when entering three-dimensional space, it can be flipped back to two-dimensional space, symmetry can be achieved, because it cannot be flipped in two-dimensional space, only rotated or translated. Therefore, we can speculate that the three-dimensional object enters the four-dimensional space, and then returns to the three-dimensional space, and the object may be "axisymmetric".

This is a very difficult calculation, because the coordinate system it establishes, in addition to length, width and height, there is also time, because there is one more, so there are countless possibilities, and it is extremely difficult.

However, Bodhi still didn't say a word and began to calculate, and she calculated very quickly, and from her eyes, it could be seen that she was really thinking, and she also looked like she had a clue.

This kind of calculation lasted for a full 3 hours, and then, Bodhi redrew a walking diagram, and then stood up, and when he stood up, his body staggered but he quickly stood up again, and said helplessly: "Hehe, I sat for a little longer, and my legs were a little numb, which of you took it to check it?" ”

Xiao Xuan and Qiye glanced at each other, and finally both of them laughed together, Xiao Xuan said directly: "If even the Qiqiao exquisite heart is wrong, if we check it again, it will be in vain, let's go, let's go through this labyrinth." ”

On this new route, the Chinese team and others re-entered the entrance, and then, walking and walking, they walked out, looking back, the maze was already behind them, they had already walked out, Bodhi's calculation was accurate. (To be continued)
