The veiled woman said in such detail, Chu Yunsheng had obtained the theoretical foundation of the ancient book, and his strength was a little transparent, and he said keenly: "You mean to say that the sunny era we lived in before was actually a kind of closed space, but the difference is that ours is a three-dimensional closed space?" ”

"You can understand that." The veiled woman nodded, pushed the model of her newly made zuò in front of her, and said: "It is really a bit troublesome to make a model of the zuò Klein bottle with a ribbon, although it is not very similar, but the meaning is okay, it is just two Mebius circles just now glued to each other, there is no distinction between inside and outside, and then you can imagine that its sides have no borders, so that the entire three-dimensional space cycle as one."

In fact, it can no longer be used as a model to describe the enclosed three-dimensional space, because it is too simple, and the real enclosed three-dimensional space can only be vividly established by standing in the four-dimensional space, just like we stand in the three-dimensional space to establish a closed two-dimensional space such as the Mebius circle, and there must be one more dimension to see the closed model of the low-dimensional space. ”

Chu Yunsheng was a little puzzled: "Since this bottle can't describe the closed three-dimensional space, what do you want to use it to illustrate?" ”

The veiled woman gestured, stretched out four fingers, and said, "The fourth dimension, use it to make you understand more clearly that the enclosing of the three-dimensional space can only be done in the fourth dimensional space, because the real Klein bottle model must also be established in the fourth dimensional space."

So what I want to tell you is that the closure of any space can only be achieved in a high-dimensional space that is at least one dimension above this space. ”

Chu Yunsheng thought for a while and said, "I can't understand, although I don't know much about science, but I've heard of it, isn't time the fourth dimension?" In this way, we are not closed, at least we can still feel the storage of time. ”

The veiled woman smiled, shook her head, and said, "At the beginning, I already said that time is not a dimension, it is just an axis, and when the axis of time and the space with dimensions are combined, a world with meaning can be established."

So for example, you can't say that two-dimensional plane space does not have zài time, and their space also has zài timeline, so if the creatures in two-dimensional space regard "time" as a dimension, they will ridiculously think that they are already living in three-dimensional space, but in fact the real three-dimensional space is what we see, with three-dimensional space such as length, width, and height, rather than a space composed of only two dimensions, length and width, and time.

As an axis, time exists in any dimensional space, one-dimensional space, two-dimensional space, three-dimensional space, and even four-dimensional space, and each space's understanding of time is also different because of the limitation of dimensions, and the law of time adapted in two-dimensional space cannot explain all phenomena in three-dimensional space, and in the same way, three-dimensional space, the theory of time in the sunshine era cannot explain all phenomena in four-dimensional space.

This kind of contradiction is like the understanding of a line by creatures in two-dimensional space, in their understanding, this line can only bend left and right, but it can never cross and pass through itself, nor can it tie a knot, but in three-dimensional space, it is normal for a line to cross and tie a knot. ”

Chu Yunsheng couldn't fully understand what she was saying, but he knew one thing, the first thing he had to do with his cultivation of the ancient book method was to break down the three-dimensional space barrier, establish a "channel" with the Heaven and Earth Yuan Qi through another dimension, and cultivate his own ontological Yuan Qi and power, and this dimensional channel may be the fourth dimension that the Veil Woman said.

So, he thought for a moment and said, "According to what you said, in the previous Sunshine Era, we were isolated from the fourth dimensional space, right?" So, what should the true fourth dimension be? ”

The veiled woman untied the ribbon, held it in her hand, did not answer Chu Yunsheng directly, pointed at him, and then pointed to Mu Xijun by the fire in the distance, and said slowly: "Actually, you already feel it, you don't need to ask me, your power, her power, all come from the laws of the fourth dimension, you can feel the existence of the fourth dimension when you calm down, if you still can't understand, I can give you another example."

In the two-dimensional plane space, we draw a circle line and put something in the circle, for the creatures in the two-dimensional space, because of the blockage of the circle line, there is no way to take this thing out of the circle. ,

And when we use the extra dimension of the three-dimensional space and take this thing away from the sky, the creatures in the two-dimensional space will feel that this thing has disappeared out of thin air and cannot understand it, and their scientists will come up with the conjecture of high-dimensional existence, and their history will give birth to many myths and legends, and even religions, but they are all used to explain the mystery of the disappearance of this thing.

Similarly, in the three-dimensional space, we can't take out the egg white and yolk from an intact egg, but the fourth dimension can, it can swagger in front of us, without damaging any part of the eggshell, and then directly take the egg white and yolk inside, for us, the egg white and yolk also magically disappear from the eggshell. ”

After Chu Yunsheng listened. But he said seriously, "I can indeed feel the fourth dimension you are talking about. But I can't get the egg whites and yolks out of the shell! ”。

The veiled woman froze for a moment. It seemed to be thundered by Chu Yunsheng's words, and he laughed and said: "You can't understand it so rigidly, otherwise you won't understand anything, you can think carefully about how your strength came from?"

If you will be your body. The flesh of zài in three-dimensional space is likened to an eggshell. Then compare those energies in the universe to egg yolks and egg whites, if there is no fourth dimension of existence. Do you have a way to "pack" this energy into your body?

The results are clear. There's nothing you can do to get that energy into your body! But take advantage of the fourth dimension. But this can be achieved very smoothly, to put it simply, it is the example of the egg I just given, but the process is exactly the opposite. In the fourth dimension of the channel, magically put the egg whites and yolks back into the eggshell! ”

Chu Yunsheng was shocked in his heart. The veiled woman's argument now was very similar to the cultivation process he had experienced from ancient books. If he didn't have the fourth-dimensional space channel to break through the three-dimensional space barrier, he really wouldn't be able to refine the Heaven and Earth Yuan Qi into his body at all, let alone any ontological Yuan Qi.

But soon a small new problem appeared, he could feel that the fourth dimensional passage was because of the ancient books, and the awakened humans could use it because they could "awaken", so why can't the rest of the people feel the fourth dimensional world now?

Chu Yunsheng guessed and asked, "So, are we now in the four-dimensional space that has been unlocked and closed in the third dimension?" Still is? ”

"It was unraveled a few years ago. But one by one", the veiled woman paused, looked at the faint light shooting out of the sky, and said, "Whether it is the closure of the space or the unsealing of the space, the process is far more complicated than the example I simulated just now. It requires a complex and changeable process. Even over and over again. This is also an important reason why we still can't see the sun, and there are still so many monsters.

It's a bit of a struggle to explain, but I can try, but it's up to you to understand it.

Let's take two-dimensional plane space as an example. Think of it as a flat sheet of white paper. If we fold it, or roll it up, whatever it is, as long as it takes on a three-dimensional shape and appears in three-dimensional space, you can think of it as the process of bringing it back from two-dimensional to three-dimensional space.

So many places that were originally not crossed on the flat white paper overlapped in three-dimensional space. This overlapping phenomenon can continue to be inferred to the fact that in the process of recovering from a closed three-dimensional space to a four-dimensional space, there is also an overlap of some three-dimensional space points, so it is not difficult to imagine why there are invading channels of bugs and monsters in many places.

But this is the true face of the world, and these overlapping points were originally created before the three-dimensional space around us was closed, and now they are only restored to the last moment before the closure.

Again, it's the same for energy, they overlap and interfere with each other, in the process. Some of the light that hits the Earth from the sun is blocked out to another place. But energy and space are different, they move very fast, and the overlapping barrier formed by the energy is completely unsealed. Calm will soon return, and the sun will be restored. ”

Chu Yunsheng nodded, a little dizzy, after the unsealing of the heavenly rail. The sun will be restored. He knew this from ancient books, but he couldn't deduce a specific date because he couldn't understand the theories. The veiled woman's explanation is more vivid and easy to understand, so she refers to Muxi County in front of the fire. "Say so." Once this process is over, and we are completely in the four-dimensional space, then will all human beings eventually "awaken" like her? And what about feeling the fourth-dimensional space channel? ”

The veiled woman did not answer him immediately. Instead, he retied the veil on his face, and after a while he said, "That's all I can sue you." You don't have to threaten me with death anymore. I admit that I will tell you so many things just now. It's because of your death threats. But the question you're asking now is already the core question!

Until I find out who you really are, even if you kill me now, I won't say anything more, because it already threatens our safety, and I really don't know much about the core issue, my mission is not this, so even suing you sounds like something unintentional.

However, there is one thing I can say to sù, and I have also told sù the people of the Botanical Forest, what you call awakening. Not necessarily a good thing. And not being able to wake up is not necessarily a bad thing, this world. Whether it's three-dimensional or four-dimensional, there is no absolute good thing or bad thing. To be continued, support the author. Support genuine reading! These two chapters may seem rather dry. But. The book has grown to more than a million words. A character needs to come out and briefly describe the principles of the worldview of this book, and there is another chapter later
