Chapter 699 Dimensionality Reduction
Li Qi, who was standing next to him, was also somewhat surprised when he heard this.
The Demon Prince was so arrogant.
He actually wanted to fight Shariputra with both wisdom and force.
And... judging from what happened later, the Demon Prince obviously won.
But, unfortunately, Li Shiwei was only a seventh-rank, and she had just reached the seventh-rank at that time. She could not understand the debate between the Demon Prince and Shariputra at all, and had no way to narrate the incident.
It seemed that no one recorded these debates, perhaps because of some taboo.
In short, the Demon Prince won both the debate and the force in that one incident.
"This is really... in line with the character." Yang Ning shook his head: "The Demon Prince... really makes people yearn for it. It would be great if I could fight with him."
"I heard that my father had a fight with him, and my father won." At this time, Li Shiwei suddenly said: "Why does it feel that my father's reputation is not well-known, but only spread around the battlefield, but the Demon Prince is famous in the world?"
"Your father... well, how should I put it, he is relatively low-key, right?" Yang Ning said so, then waved his hand, raised his voice, and shouted to Li Qi who was pretending over there: "Li Qi! Stop pretending, come here!"
Li Qi was stunned.
Can Yang Ning actually see it? This is really-
This is unlikely to be done through perception. Li Qi is confident that he has been promoted to the fourth rank, and Yang Ning will definitely not be able to see it clearly, so... Yang Ning is guessing purely based on his understanding of himself.
Obviously, they haven't seen each other for so long, but I didn't expect this sister-in-law to be able to make such a judgment.
Since he was exposed, he naturally didn't pretend anymore, put down the cup in his hand, and walked to the table on Yang Ning's side.
Li Qi arrived, and Li Shiwei was obviously more restrained.
Yang Ning, who had called him over, also had a complicated expression.
How should I put it? When Yang Ning really felt Li Qi's fourth-grade power, he always felt a little sour.
"I thought you wouldn't call me." Li Qi smiled and sat over.
"I didn't want to call you, you're so annoying, so pretentious." Yang Ning pouted: "I really don't know what she likes about you."
Li Qi just smiled and didn't answer.
Compared with Yang Ning and Li Shiwei, he did seem a little rigid, but there was nothing wrong with it. He really couldn't do such a thing as being unrestrained.
"Okay, let's not talk about this. I called you here just to ask you, how did you beat the Demon Prince in the first place?" Yang Ning asked.
"Well, it's impossible to win in a battle of the same level, so I thought of a way at that time, took a shortcut, broke through in the battle, and won by beating the opponent with a high score, but... the price was not small, and I spent a lot of energy later, and the teacher helped me, so I solved the sequelae." Li Qi said with a smile.
He said it very easily at the moment, but this matter was indeed a bit difficult. He really fought with Zhiren head-on to get rid of it.
It's as difficult as ascending to heaven. Even if it happens again, it's hard to say whether he can come back alive.
Li Qi's relaxed look made Yang Ning look at him again.
Then, Jinwu patted Li Shiwei: "Your father is also not easy. You go and play first, and I'll let him come over to talk to you alone later."
"Aunt——" Li Shiwei wanted to say something.
But in a sense, she still inherited Li Qi's obedience to the rules. Although she was a little dissatisfied, she still chose to leave on her own initiative to make room for her aunt and father.
After Li Shiwei left, Yang Ning sighed: "It's only been a short time, and you've already reached the fourth rank..."
"It's not as easy as you think." Li Qi said.
"Of course I know it's not easy. How can it be easy to enter the fourth rank? I just... Oh, forget it, I don't know how to say it, I can't explain it clearly." Yang Ning's tone was a little subtle, and he couldn't tell what he felt.
A mixture of emotions, maybe that's it.
I have lost the so-called "jealousy" or "admiration" and the like. It's really complicated and hard to describe what I feel. Even though I'm already at the fifth rank, Yang Ning can hardly describe what I'm thinking now.
All the thoughts are mixed together, and the words don't make sense. Just a second ago, I was still talking about adventures with my little niece, but the topic turned to Li Qi inadvertently.
Whether it was inadvertent or intentional, even Yang Ning himself couldn't tell.
"There's no need to dwell on these. Everyone has their own way. Walking fast doesn't necessarily mean walking steadily." Li Qi said so.
This is not comfort, Li Qi thinks so from the bottom of his heart.
He is still trembling with fear and being cautious, not daring to slack off.
The higher you get, the more you feel like you are walking on thin ice. The Tao has a nearly infinite power, which can shape the world. Today's real world is shaped by the Tao.
The Tao-chasers want to understand the Tao and pursue the Tao, but the more they advance, the more they will find the nothingness of the real world and the solidity of the logical system itself.
The Tao-chasers are trying to pursue and control this power. They look for traces of the Tao in logic, theory, thought, and symbols.
Such power is almost only subject to logic, or in other words, this is logic itself. The world itself is born from logic in nothingness.
The more you understand, the more you fear this power, and the more you worry that you will go the wrong way.
In this case, "fast" is not necessarily a good thing. If you just want to be fast, then directly merging with the Tao is the fastest shortcut.
"It's not about whether it's fast or not, but... you can clearly know what you want, what you're afraid of, know where the road is, and you can also distinguish many forked roads at critical moments. This is much more important than practicing fast. There are too many. To be honest, I have thought about a lot of ways to go to the fourth level. There are hundreds of thousands of ways to go, but I don’t know which way to go, and I can’t tell which one is right. "Yang. Ning sighed.
What she envied most about Li Qi was also his true 'talent'. He had a completely intuitive sense of his own path, and he could always walk on it without hesitation.
"The more you struggle with these things, the less you can do it. What you have to take is your own path, not the right path. As long as you practice your own path, there is no such thing as severing the path, because You have reached your end, not the end of the road, but the end of you."
"If you follow the 'right path', even if you succeed in getting promoted, I think... you won't be able to continue on that path, right?" Li Qi said.
If you follow your own path, you may indeed be cut off, but it is your own path after all.
If we follow the path of our predecessors and absorb their experience, we won't get far.
But when Yang Ning heard this, he rolled his eyes: "It doesn't hurt when you stand and talk. The purpose of cultivation for all living beings is different. You are a genius. The Witch God has high hopes for you. Of course you can go your own way, even if you can only walk Your own path, because you have the task of opening up a new path, but we are different. Now I just want to become stronger quickly so that life in Luofu Mountain can be easier."
Li Qize continued to smile and said: "The path you choose to become stronger and protect Luofu Mountain is also your own path, isn't it? Who said you have to like your own path?"
"To put it simply, your own path... no matter how you choose it is your own path, but how many people don't regret taking it out? To put it bluntly, forget it, saying this to people like you is embarrassing yourself. That's all." As Yang Ning spoke, she felt a wave of irritation welling up in her heart.
It was really crazy that I would ask Li Qi to talk about these topics.
People don't have this kind of trouble.
But Li Qi continued: "Maybe you think it's all nonsense, but... in fact, it is still very useful. At least it can eliminate anxiety. I also had this kind of anxiety when I was promoted to the fourth rank, but later I discovered that, It’s actually of no use.”
"All things seek is nothing more than self-consistency."
Yang Ning just shook his head: "Self-consistency, so what if your self-consistency does not match reality?"
"If it doesn't match reality, then it doesn't match. Is the universe like this from the beginning? What if there is another possibility for the universe? Maybe not just another one, but countless other possibilities. As long as it can be established based on logic, If it has a complete description, it can actually be considered valid, right?”
"Look, for example." Li Qi said, stretched out his hand and waved out a piece of Taoism, covering the wine glass in front of him, and naturally re-described the surrounding 'space': "As long as you do this, you can combine the vectors of the three dimensions of the space. After stretching, translation, and rotation, a super-parallel polyhedron is formed. You see, some dimensions are flattened, and the scaling rate in that direction becomes 0. The scaling rate of the volume changes, causing it to lose part of its characteristics. Also, a direction is lost.”
With Li Qi's description and a less complicated description of matrices and determinants, space collapsed.
Space itself has not collapsed, because time and space do not exist at all, but there are only two directions within which matter can move in this space.
In the ordinary world, this would have gone in three directions.
However, matrix A can be expanded into a three-dimensional space, but after left multiplication by matrix B, the new description generated, the world described by the newly emerged matrix C, can only be expanded into a two-dimensional space.
That is, there is one direction in space that is ‘flattened’.
It has been hit by dimensionality reduction. A direction that represents the scope of material action has been flattened. A new 'description' has limited space to this. The essence of space has not changed, but now matter cannot go in that direction. .
Space-time tells matter how to move. Now this small piece of space-time tells matter: "You can only move in two directions. As for why? Because other people told me this is the case."
Who told that?
Of course it was Li Qi, who was already at level four.
This is the power of the fourth grade.
Li Qi said easily: "You see, as long as you slightly change your interpretation of the world, the phenomena will also change. In fact, there is no change in the definition of matter or space. It's just that... the interpretation has been modified. , so everything naturally became like this.”
Yang Ning stared at the wine glass in Li Qi's hand.
This wine glass was 'flattened', but it was not flattened into a 'painting', but stripped away and turned into a 'thread'. These lines seemed to be infinite and constantly circling. , entangled, forming an extremely complex pair, but the special shape of the wine glass can no longer be seen.
This is still a wine glass. Yang Ning can feel that the nature of the matter in it has not changed, and the space itself has not changed. However, because there is one missing direction, it has become this continuous fractal curve, which can fill two- and three-dimensional spaces infinitely. , and finally got a three-dimensional wine glass composed of voxels on a two-dimensional plane with both external and internal details.
Yes, the wine glass was unfolded in two dimensions and turned into an infinite fractal curve. The inside and outside of the wine glass were simultaneously displayed on the two-dimensional plane, but this two-dimensional plane was an infinite fractal geometry, with the characteristic of filling space in the form of non-integer dimensions.
She didn't know what it was, but Li Qi had already shown it to him.
In the real world, such a weird and confusing state could never exist, but it could exist logically.
However, as long as it could exist logically, it meant that this phenomenon could exist, because it did not violate logic, which meant that there was no paradox, and if there was no paradox, all we had to do was create this phenomenon.
Just like a brand new element in the laboratory, such as element 118 on the periodic table, which absolutely did not exist in the real universe, but as long as it was logically clear and there was a complete theory as the basis for its existence, it was not impossible to forcibly create this completely new element in the laboratory that the universe had never synthesized on its own.
In fact, humans have already done this.
What Li Qi did was just a little higher than that.
Those spaces that only exist in logic, the three-dimensional Hilbert curve composed of fractal geometry and material voxels that only exist in mathematical descriptions, these strange phenomena that he can describe can all be directly presented as "reality", and what supports all this is his Tao and cultivation.
Yang Ning stared at the wine glass, she understood what Li Qi wanted to tell her.
But... she couldn't do it. Understanding the principle is one thing, and actually doing it is another thing. This is what makes people hate it.
So, Yang Ning turned her head and changed the topic: "Now I know why you are not liked by Shi Wei. Do you like to say these things when you are with her?"
Li Qi was stunned, then smiled bitterly, and the dimensionality reduction space in his hand returned to normal, but the wine glass also twisted and collapsed directly, turning into a pile of waste that could not see the original shape.
Dimensionality reduction transformation is actually a projection from high dimension to low dimension. This transformation and projection is like flattening a globe and drawing it into a flat map. The information in it is definitely lost. Therefore, even if the space is restored, the lost information cannot be recovered, and naturally it will not be restored to a three-dimensional form.
This is entropy, information lost can never come back.
