Yan Hua continued: "Let me explain the four-dimensional space to you first, before I told you that the four-dimensional space is one more dimensional than the three-dimensional space, let me first assume that there are a group of intelligent creatures living in the two-dimensional space, they are flat people, that is, the so-called two-dimensional creatures, they can only see the line when they see the world in the two-dimensional space, the perspective between the two-dimensional creatures, the so-called life and objects are lines of different lengths, and we, that is, human beings, I call it three-dimensional creatures, we see all the surfaces, and then go further."

And when two-dimensional creatures are placed in three-dimensional space, and then look at the original world, they can also see the whole picture, that is, the plane, such as a landscape painting, then when three-dimensional creatures are put into four-dimensional space, and human beings use their eyes to see the three-dimensional space, what will it look like?"

Li Qing was stunned for a moment, she vaguely understood something, but she still couldn't use her mouth to get out of the feeling, stuck in her throat.

Yan Hua explained with a smile: "To put it simply, it is the kind that can see all faces, perspective, I can not only see your front, but also see your back, and I can also see your internal organs, which are clearly visible, and everything in the closed object can be seen clearly in the four-dimensional space." ”

"Is that so? It's not that people have no secrets. Li Qing imagined the picture that Yan Hua said, shuddered a little, and instinctively hugged his hands in front of his chest.

"Hehe, yes. ”

Yan Hua took a sip of coffee and continued: " It is difficult to describe the high dimension in words, because we are three-dimensional creatures after all, not four-dimensional creatures, we can only understand through some logical reasoning, plus the facts we understand, such as four-dimensional space, it is very appropriate to describe it with such an example, the barbershop was very small in the past, and the owner of the barbershop in order to increase the sense of space, will put two mirrors on the front and back walls, when you sit in the barbershop, you will find that the space is very large, because the space in the mirror is infinitely extended, bottomless, this is the four-dimensional space, and our three-dimensional space is just one of the images in the mirror。 ”

Li Qing's eyes widened slightly, his mouth opened slightly, and he wanted to say something, but he closed it again.

The picture that came to her mind was naturally the picture that Yan Hua described, which made her feel very real and appropriate.

"If you think about it, our universe is a thin piece of paper with 16 billion light-years of paper, and the universe we see is deep and vast, and the world is just a cross-section of the four-dimensional space. Yan Hua also had a hint of amazement on his face.

The human mind is a very interesting existence, it is very illusory, but it is real, and every human being has an independent mind, which is even more amazing.

Yan Hua continued: "Let's go back to the question itself, what form will the real body exist in the world of fiction?"

Li Qing immediately said, "Could it be in the four-dimensional space?"

Yan Hua shook his head and explained: "This is impossible, because you said that you have been attached to a character in the world of the novel, then the real body of this character exists in the four-dimensional space, how can the spirit exist in the three-dimensional space? According to your hypothesis, the spirit and the body are separated, and there is no scientific verification that the human spirit can be separated from the body, that is, the so-called soul existence." ”

At the same time, he continued: "Now we assume that there is really a connection point between the three-dimensional space and the four-dimensional space, and the three-dimensional space is one of the cross-sections in the mirror corridor, and the connection point is naturally the three-dimensional space, and there is a bulge on its surface, so we regard it as a bubble, and this bubble temporarily connects the three-dimensional space and the four-dimensional space together, if people enter this bubble point, if they can survive normally, then they can temporarily see the three-dimensional space through the perspective of the four-dimensional space, and see everything." ”

"But if it coincides with the real body of a fictional world, and the spiritual world is superimposed, I now think that there should be a special area between this bubble, that is, between the three-dimensional space and the four-dimensional space, which is formed at the junction of the three-dimensional and four-dimensional space, which cannot be determined and described, but if the character who appears in the fictional world from the real world really lives in a possessed form, then her body should be in this special area, and she herself and the consciousness of the body itself have formed a special opposition, or it is possible to merge。 ”

Li Qing still basically understood, although she had to be separated from the three-dimensional space, Yan Hua described it very well, her thoughts flowed, she remembered that Li Xue said that she would communicate with Wu Mengjie in her dreams, and even share her memories, which just confirmed a certain guess phenomenon of Yan Hua.

Li Qing said with a smile: "Perhaps, the possessed person and the person in the novel world, the two can meet in dreams, and memories can check each other." ”

Yan Hua also said with a smile: "This is also a very interesting description, but the characters of the two worlds are fused together in such a special way, which is very special in itself, what kind of changes will happen, it is difficult to say, everything can happen." ”

Li Qing then asked: "That person really went from the previous world to the world of fiction, and it is a real body, will she have special abilities? such as stealth, through walls or something, can this ability be controlled?"

Yan Hua asked the waiter to refill a cup of coffee, took out a cigarette again, and said, "We seem to have said a similar question last time, that time it was about people in the real world going to the world of fiction, will the real body be harmed, right?"

"Hmm. Li Qing nodded.

"Then according to the last theory, people from the real world arrive at the world of fiction, in fact, they are other life forms, assuming that they are all carbon-based life forms, and the environment and conditions of survival are the same, and it is a special state for human beings to enter the world of fiction in the real world, which is not a high-dimensional to a low-dimensional, but a dimensionality reduction in another sense, after all, the space we live in and the world of fiction are three-dimensional space, but they are not the same space, but the world of fiction is indeed based on the real world, so it is also 'dimensionality reduction'. ”

Yan Hua continued: " Everything we say is to assume the existence of the fictional universe, otherwise everything is not true, in this case, our real body is a very special state in the fictional universe, although the two universes are extremely similar, and human life is almost the same, but the essence is still different, even if the rules are exactly the same, but they are still two rules, just like two twins, even more like twins, but the essence is still different, his set of rules does not apply to real human beings, human beings in a sense, have special powers, according to religious description, that is, the power of God。 ”
