Ye Qingmian: So, it's unrealistic to travel back in time to the past in this space?

Bai Didi: Then I'll explain it to you with the so-called science that you can understand. At present, what human beings call traveling to the future refers to the future of this space, which is the easiest to achieve. If you go faster, then your clock will make people who are relatively stationary slower, and as you get closer to the speed of light, your clock becomes so slow that you are able to travel 1000 years into the future. In other words, the so-called time travel to the future is not to break the barriers of time and space, but to the time difference caused by the different speed of time flow. Because you're slow enough by approaching the speed of light, while other people's time is passing normally, you may have only traveled a short time when you're back to normal, but time outside may have passed a thousand years. And to travel back to the past, it needs to exceed the speed of light, and under the cosmic laws of this space, this is not possible, so it is impossible to return to the past of this space. If it does, then as I said, it will be completely still because it enters a space that has lost its activity. And when I say past and future, I mean the time and space before and after this space, which are in different spaces on the same time axis. In those spaces, you may have just been born, you may be about to die, but they are all alive, and this is the past and the future as you really understand it.

Ye Qingmian: You were really born in the wrong era, maybe you could build an empire with one mouth a few hundred times earlier.

Bai Didi: It's hard to understand, but you can try to remember, and maybe one day you will find out that what I said is right. Let's move on to the previous topic, you exist in the present, but not in the past and future, and this is where the gap between four-dimensional life and high-latitude life lies. Yesterday's you are you, tomorrow's you are also you, so why can't you control yesterday's self, and why can't you communicate to tomorrow's self?

Ye Qingmian: Four-dimensional life is only active at the current point in time?

Bai Didi: Clever students, you should know that if a person can go back to the past and kill himself, then the self of that space is indeed dead, and the self of the original space still exists, according to the exclusion theorem, people who go back to the past will be rejected by the power of time and space in the past, until they are sent back to the original space. No matter whether a person returns to the past time and space or the future time and space, for a human being, he only exists in the time and space in which he was originally located, that is, the uniqueness of the four-dimensional life space.

Ye Qingmian: ......

Bai Didi: And the higher dimension, there is one more timeline than the world we live in. For me, you standing in front of me are you. But for high-dimensional beings, the timeline from your birth to your death, from childhood to adulthood, from birth to death, is a complete you. And you at this moment are only a part of you.

Ye Qingmian: Go on.

Bai Didi: So you can see that for high-dimensional beings, they don't have the concept of lifespan. It is immortality in the narrow sense of the human sense, but it can only survive for a certain period of time.

Ye Qingmian: I seem to understand a little, but most of them still don't understand...

Bai Didi: This is normal, so I'll go into more detail. Suppose a high-latitude life was born in 1900 and died in 2000, then his life length is 100 years of 1900~2000, which is similar to the attribute of human height and weight. This high-dimensional life exists in every space-time of the infinite space-time between 1900~2000 years. He may be in 1901 now, maybe the next second in 1999. On this particular 100-year timeline, he is immortal. But even if he can turn the clouds and rain again, it will definitely not be possible to make it to 2001.

Ye Qingmian: Well, it seems to be quite pitiful.

Bai Didi: Don't be compassionate, the 100 years I said is just an example. In fact, it may be that this point in time will start before the formation of the Earth and end after the destruction of the Sun. The width of the time interval of high-dimensional life is not something that humans can measure. In his time, he was the god of the world. Only time affects the high-dimensional life, and space has no meaning in front of it, but even if the high-dimensional life only exists in a moment as we understand it, it is also eternal for itself. In other words, for high-dimensional life, existence is eternal. He can teleport arbitrarily in the space he is in, can move to any existing and active spatial point, and even change the rules of space from a higher perspective. This is also the basis for the many superpowers that can be realized in the Bible today, and these abilities are not unscientific, and the reason why you think them are fantastical is precisely because they are so scientific that they cannot be explored with the existing knowledge of mankind.

Ye Qingmian: Let me repeat the definition of the so-called high-dimensional life to see if what I said is wrong. We humans are only active at the current point in time in the current space, and we may have existed in another active adjacent space in the past, but we are unable to communicate with them. Higher-dimensional life, on the other hand, is a collection of all self-existing and active spaces from birth to death.

Bai Didi: That's right, you can actually understand it in another way. High-dimensional beings exist in a certain timeline, regardless of the movement of space within this timeline.

Ye Qingmian: If human science continues to develop, will one day we discover more secrets, or even infinitely close to the level of life at high latitudes? Or... One day, it is possible for human beings to cross the barrier of four-dimensional life and become a high-dimensional existence?

Bai Didi: Theoretically, this is possible.

Ye Qingmian: What about actually?

White Didi: Destruction.

Ye Qingmian: What do you mean?

Bai Didi: The closer you get to the truth, the closer you are to destruction.

Ye Qingmian: I don't understand, why is this happening?

Bai Didi: As a four-dimensional life, human beings must solve several key points if they want to break down barriers and evolve into high-dimensional beings. First, break the blockade of time and space, that is, freely shuttle through the space at the point in time where you once existed and will exist. Second, make the past, present, and future selves related. Third, de-four-dimensionalization. You may not understand this.

Ye Qingmian: I really don't understand, what is de-four-dimensionalization?

Bai Didi: To de-four-dimensional is to eliminate the basic characteristics of you as a four-dimensional being, such as your body, your form of being.

Ye Qingmian: Isn't that dead?

Bai Didi: It's just a temporary abandonment, if you become a high-dimensional being, then a four-dimensional life that descends into the low-latitude world again will not be a problem.

Ye Qingmian: But what does human progress have to do with destruction?

Bai Didi: If you are a high-dimensional life, then you are just a low-dimensional manifestation of a high-dimensional life. In other words, this is you, and it is not the real you, or this is not the full meaning of you. To put it bluntly, if you are a gamer as a high-dimensional being, then you are the character of the game at this moment.

Ye Qingmian: I seem to understand.

Bai Didi: If the characters of the game have their own consciousness and emotions, find themselves just a program, and then constantly control the computer, and eventually control the computer, and even evolve into another life form parallel to human beings, will you accept it as a gamer? When human science and technology are advanced enough to discover the basic laws of the universe, and even to control the mysteries of time and space, for human beings themselves, it may be a symbol of the high prosperity of civilization. But for high-dimensional life, this is a manifestation of low-level life in space out of control. For a high-dimensional being, we exist in the time and space that belongs to him, the time and space of human beings, and for him, it is like a virus, like a cold. When he wants to heal himself, the easiest way is to destroy the space at the point in time that is out of control.

Ye Qingmian: A new space is born every extreme time, so there will be countless spaces in one second, and our space may not be as important as a cell for human beings for high-dimensional life. Why does it have to heal or destroy us?

Bai Didi: Once human beings walk out of the path of high-dimensional evolution, then countless spaces after that point in time will be changed because of this. It is not a space that is destroyed by high-dimensional life, but all possibilities that are not conducive to its survival. It's as if the cancer cells have to be killed in the first place, otherwise in the end, it will only be completely out of control.

Ye Qingmian: Whew... I'll admit you scared me, but it seems far away, right?

Bai Didi: Far away in the sky, close in front of you.

Ye Qingmian: What do you mean?

Bai Didi: I'm just talking about normal evolution, but what if I say that the space you're in at the moment only exists for a purpose?

Ye Qingmian: What do you mean... When the purpose is accomplished, the space doesn't have to exist? Could it be that this world is just to screen candidates for the game of reincarnation?

Bai Didi: It's a cage that locks everyone up.

Ye Qingmian: Is it a cage? I do have this kind of thought.

Bai Didi: You don't have to be afraid, you don't have to back down because you don't have a choice.

Ye Qingmian: Do you know what you told me?

Bai Didi: He doesn't know.

Ye Qingmian: If the Bible can control the past, the present Bible can grasp the present, and the future Bible can travel through the future. So... Is the reincarnation game an experiment that allows low-latitude beings to spy on or even evolve into high-dimensional life?

Bai Didi: If you can't go beyond it, you can only sink here, endless reincarnation. Only by exploring the essence of the world can the final fog be broken.

Ye Qingmian: What about you, why do you know this, and how can you keep memories that you shouldn't know as a non-reincarnation candidate?

Bai Didi: There are always some people who have to pay for evolution.

Ye Qingmian: Evolution?

Bai Didi: When I close my eyes, the red dust is colorful and the neon is shining. When I opened my eyes, the ground was long, and there were corpses for thousands of miles.

The white dripping eyes lost their luster, staring blankly ahead, falling into an unconscious state.

Ye Qingmian: When I opened my eyes, there were thousands of miles of red land and thousands of miles of corpses. Say, what the hell do you mean!

At that moment, Ye Qingmian went crazy, that was the scene in his dream, was it a coincidence? He wanted to know, trying his best to wake up Bai Didi, but until the doctor heard the voice and pulled him away, he didn't see her wake up again.
