Wandao long distance

Chapter 699 Dimension Reduction
Li Qi next to him was also a little surprised when he heard this.

The devil prince is so arrogant.

He actually wanted to confront Shariputra in two aspects of wisdom and force.

And... Judging from what happened later, the devil prince obviously won.

But, it's a pity that Li Shiwei was only at the seventh rank, and she was only at the seventh rank at that time. She couldn't understand the debates between the devil prince and Shariputra at all, and she couldn't explain it.

It seems that no one has videotaped these debates, maybe there is some taboo.

All in all, the devil prince won both the debate and the confrontation in that one time.

"This is really... in line with the character." Yang Ning shook her head: "The Demon Prince... is really fascinating. It would be great if I could have a 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 do you feel that your father's reputation is not obvious, but only spread around the battlefield, but the devil prince is famous all over the world?"

"Your father... well, how should I put it, he's relatively low-key, right?" Yang Ning said so, then waved her hand, raised her voice, and shouted at 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 has absolutely no way to see clearly, so... Yang Ning guessed purely based on her understanding of herself.

I haven't seen each other for so long, I didn't expect this sister-in-law to make such a judgment.

Now that he was exposed, he naturally stopped pretending, put down the cup in his hand, and walked to the table over by Yang Ning.

When Li Qi arrived, Li Shiwei was obviously restrained a lot.

Yang Ning, who just called him over, also had a complicated expression.

How should I put it, when Yang Ning really felt the power of Li Qi's fourth grade, Yang Ning 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 at first, you are too annoying, you're just pretending." Yang Ning curled her lips: "I really don't know why she likes you."

Li Qi just smiled and didn't answer.

Compared with Yang Ning and Li Shiwei, he does seem a bit rigid, but there's nothing wrong with it. He really can't do such things as being wild.

"Okay, let's not talk about this, I just want to ask you, how did you win the devil prince?" Yang Ning asked.

"Well, you can't win a match at the same level, so I thought of a way at the time, took a shortcut, made a breakthrough, and won by fighting high and low, but... the price was not small, and a lot of energy was spent on it later. , and the help of the teacher, this is the cure for the sequelae." Li Qi said with a smile.

It's easy for him to say at the moment, but this matter is indeed a bit difficult, and he really got rid of it after fighting with Zhiren head-on.

It's as difficult as climbing the sky, even if it is to do it again, it's really hard to say whether you can come back alive.

Li Qi's relaxed look made Yang Ning look at him again.

Then, Jinwu patted Li Shiwei and said, "It's not easy for your dad, either. You go and play for now. I'll ask him to come over and talk to you alone later."

"Aunt—" Li Shiwei wanted to say something.

However, in a sense, she still inherited Li Qi's way of following the rules. Although she was a little dissatisfied, she still chose to leave voluntarily to make room for her aunt and father.

After Li Shiwei left, Yang Ning sighed: "It's only been a while, 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 step into the fourth rank? I just... Oh, forget it, I don't know what to say, I can't explain clearly." Yang Ning's tone was a little subtle, and she couldn't tell what it felt like.

Mixed flavors, maybe that's it.

I have already lost the so-called 'jealousy' or 'admiration'. It is really complicated, and it is difficult to describe what kind of mood it is. Even if it is already a fifth-rank, it is difficult for Yang Ning to describe what she is thinking now. .

All the thoughts were mixed together, and the words didn't match up. Just a second ago, he was talking about adventures with his little niece, but the topic turned to Li Qi inadvertently.

Whether it was inadvertently or on purpose, even Yang Ning herself couldn't tell the difference.

"There is no need to worry about these. Everyone has his own path, and walking fast may not be steady." Li Qi said.

This is not comfort, Li Qi thinks so from the bottom of his heart.

He is still trembling and cautious, not daring to slack off in the slightest.

The more you come to a high position, the more you can feel that you are walking on thin ice. "Tao" has almost infinite power. This power can shape the world. Today's real world is shaped by "Tao".

The Taoists want to understand the Tao and pursue the Tao, but the more they advance, the more they will discover the nihilistic nature of the real world and the solidity of the logical system itself.

The Taoists are trying to chase and control this power, and they are looking for traces of the 'Tao' from logic, theory, thought, and symbols.

This kind of power almost only succumbs to logic, or in other words, this is logic itself, and the world itself is born of logic in nothingness.

The more I understand, the more I fear this power, and the more I worry that I will go the wrong way.

In this case, 'fast' is not necessarily a good thing. If you just want to be fast, then joining the Tao directly 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, where the road is, and you can distinguish many forked roads at critical moments. This is faster than practicing, and it's much more important. There are too many, to be honest, I have thought a lot about the road to the fourth rank, not to mention too many, there are always hundreds of thousands, but I don't know which one to take, and I can't tell which one is right." Yang Ning sighed.

What she envied most about Li Qi is also where Li Qi's real 'talent' lies. He has a completely intuitive sensitivity to his own path, and he can always walk on it without hesitation.

"The more you struggle with these things, the worse it will be. What you have to walk is 'your own way', not the 'right way'. As long as you practice your own way, then there is no such thing as a broken way, because You have come to the end of yourself, not the end of the Tao, but the end of you."

"If you go on the 'right way', even if you are promoted successfully, I don't think...you can't go on, isn't it?" Li Qi said.

Walking one's own way may indeed lead to a dead end, but it is one's own way after all.

If we follow the path of the predecessors and absorb the experience of the predecessors, we will not go far.

But Yang Ning rolled her eyes when she heard this: "It doesn't hurt to stand and talk, and the purpose of all living beings' cultivation is different. You are a genius, and the witch god has high hopes for you. Of course you can go your own way, or even you can only go your own way." Your own path, because you shoulder the task of opening up a new path, but we are different, I just want to become stronger quickly, so that life in Luofu Mountain will be easier."

Li Qi continued to smile and said: "Isn't the path you choose to become stronger and protect Luofu Mountain also your own path? Whoever says that you have to like your own path?"

"To put it simply, your own path... No matter which way you choose, it's your own path, but how many people don't regret it after stepping out? To put it bluntly, forget it, talking about this with someone like you is a shame. That's all." Yang Ning felt a burst of irritability rushing into her heart as she spoke.

It was really crazy that I would ask Li Qi to talk about these topics.

People don't have such troubles.

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.”

"Everything, what you want is nothing more than self-consistency."

Yang Ning just shook her head: "Self-consistent, what if your self-consistent and reality do not match?"

"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 method, it can actually be considered established, right?"

"For example, look at it." Li Qi said, reaching out and waving a piece of Taoism, covering the wine glass in front of him, and naturally re-describing the surrounding 'space': "As long as you do this, the various vectors of the three dimensions of space After expansion, translation, and rotation, a superparallel polyhedron is formed. You see, some dimensions are flattened, and the expansion rate in this direction becomes 0. The expansion rate of the volume changes, resulting in the loss of some features. What’s more, one direction is lost.”

Following Li Qi's description, and a less complex description of matrix and determinant, the space collapsed.

Space itself has not collapsed, because time and space do not exist at all, but the range that matter can move in this space is only two directions.

In the normal world, this would have gone in three directions.

However, matrix A can be stretched into a three-dimensional space, but after multiplying matrix B to the left, the brand-new description generated, the world described by the newly emerged matrix C, can only be stretched into a two-dimensional space.

That is, there is one direction in space that is 'flattened'.

It has been hit by dimensionality reduction, and a direction representing the action range of matter has been flattened, and a brand-new 'description' has restricted space to this shape, and the essence of space has not changed, but now matter cannot go in that direction .

Space-time tells matter how to move, and now this small piece of space-time tells matter: "You can only move in two directions. Why? Because someone else told me so."

Who told that?

Of course it was Li Qi who was already at the fourth rank.

This is the power of the fourth rank.

Li Qi said relaxedly: "Look, as long as the interpretation of this world is slightly changed, the phenomenon will also change accordingly. In fact, no matter whether it is the definition of matter or the definition of space, there is no change at all. It is just... a revised interpretation. , so everything naturally became like this.”

Yang Ning stared at the wine glass in Li Qi's hand.

This wine glass has been 'squashed', but it is not the kind of squishing that becomes a 'painting', but it has been stripped and turned into a 'line'. These lines seem to be infinitely numerous, constantly circling , intertwined, forming an extremely complicated 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 substance in it has not changed, the space itself has not changed, but because there is one less direction, it has become this continuous fractal curve, which can infinitely fill two-dimensional and three-dimensional space , and finally a three-dimensional wine glass composed of voxels on a two-dimensional plane with both external and internal details is obtained.

Yes, the wine glass, being unfolded two-dimensionally, becomes an infinite fractal curve, and the inside and outside of the wine glass are displayed on the two-dimensional plane at the same time, but this two-dimensional plane is an infinite fractal geometry, and it has the filling in the form of non-integer dimensions. properties of space.

She didn't know what it was, but Li Qi had already shown him all of this.

In the real world, such a weird and confusing state is absolutely impossible, but logically it can exist.

However, as long as it can exist logically, it means that this phenomenon can exist, because if it does not violate logic, it means that there is no paradox, and if there is no paradox, it is enough to create this phenomenon.

Just like the brand-new elements in the laboratory, such as element No. 118 on the periodic table, the real universe absolutely does not exist, but as long as it is logically clear and there is a complete theory as the basis for its existence, then in the experiment In the chamber, it is not impossible to forcibly create this completely brand new element that the universe has never synthesized by itself.

In fact, humans already do this.

What Li Qi did was only a little higher than that.

The three-dimensional Hilbert curves composed of fractal geometry and material voxels that only exist in logical space and exist only in mathematical descriptions. These strange phenomena that he can describe can all be directly displayed as 'reality'. And what supports all of this is his Tao and cultivation.

Yang Ning stared at the wine glass, she understood what Li Qi wanted to tell her.

But... she can't do it. It's one thing to understand the principle, but another thing to actually do it. This is what makes people hate it.

So, Yang Ning turned her head and changed the subject: "Now I know why you are not liked by Shi Wei. Do you also like to talk about these things when you are with her?"

Li Qi was stunned for a moment, then smiled bitterly. The dimensionality reduction space in his hand returned to normal, but the wine glass also twisted and collapsed, turning into a pile of scraps with no prototype.

Dimensionality reduction transformation is actually a projection from high-dimensional to low-dimensional. This kind of transformation and projection is like flattening the globe and drawing it into a flat map. The information in it must be lost, so even if the space is restored, the loss It is impossible to get back the information, and naturally it will not restore the three-dimensional form.

This is entropy, and once information is lost it never comes back.
