In the refining room, Yang Chen sat cross-legged and meditated, his five hearts facing the sky, his form and spirit were introverted, but his essence was the only one, silently contemplating the Dou Da rune in the Spirit Palace. Pen "Fun" Pavilion www.biquge.info

This runic dragon and phoenix seal, octagonal hanging, looks endlessly changing. It's as if it's changing shape over time. But if you look closely, you can see that this change of form does not seem to exist. The rune was as if it had remained the same from eternity to eternity, unchanged.

This state of flux and eternity, and an indescribable spiritual charm, is quietly hidden, making people look at it as if they have infinite understandings, but the specific enlightenment is indescribable, unclear, and even elusive.

If you look closely, this rune is not a planar type, but a three-dimensional shape or even a more complex spatial topology. Even if Yang Chen's current analysis results are concerned, it is an existence with three-dimensional space, and even four-dimensional, five-dimensional or even more dimensional spatial structure. Yang Chen knew that only the higher his comprehension of it, the more he would be able to grasp its true face.

He even more faintly felt that if he wanted to completely reveal his true face, even at the level of Yang Chen's previous planetary level cultivator, he still felt that it was a distant thing. This was a feeling that Yang Chen couldn't give him with all the runes he had been exposed to before.

It can be said that the truth of all runes is the existence of high-dimensional space topology: all runes, although they appear to be flat when written, are in fact only projections on a flat surface, strictly speaking. The two-dimensional rune structure is the simplest and easiest to understand, and it is just the right time to slowly comprehend the true meaning of the rune.

In fact, even the runes contained in the seventy-two particle equations of the first order that Yang Chen has now mastered are actually the manifestations of multi-dimensional bodies in two-dimensional space in later research.

This is why, even the most basic runes, still have extremely high research value, and can even be said to be broad and profound, and there are almost endless contents to study.

However, there are still differences in the highest dimensional space of different runes. The higher this highest dimensional space, the greater the development potential of the rune. However, even the most basic runes that have no development potential and basically belong to the composition of first-order particle equations and the like, their true face is at least the existence of a four-dimensional space.

Even if it is the research of later generations, the highest is only a preliminary extension to the five-dimensional topology, as for the higher dimensions, it can only be said that there is such a thing, but what it is, I still don't know anything.

And the rune that Yang Chen visualized, even from the perspective of later generations, still couldn't see the details clearly, which meant that the true dimension of this rune was probably far more than the five-dimensional level.

This alone made Yang Chen ecstatic.

Because the higher the true dimension of a rune, not only the greater the development potential, but also the closer to the laws of the universe, once it is displayed in actual combat, even if it is just an incomplete display of two-dimensional and three-dimensional projections, the power is also powerful!

The best thing was that although Yang Chen looked unfathomable and completely incomprehensible to this rune, Yang Chen still knew that this rune that appeared in his Spirit Palace appeared in a complete state. It's just that my understanding and research of it is limited, so the real high-dimensional form I can't see, but it still exists in the Spirit Palace.

This was completely different from the other runes that Yang Chen had engraved in the Spirit Palace before.

The runes engraved by Yang Chen before were just low-dimensional projections of the true form of those runes. Due to the influence of Yang Chen's lack of cultivation, this low-dimensional projection is only two-dimensional. The high-dimensional part is completely blank. If you want to be able to upgrade to three dimensions or even more dimensions, you must also have Yang Chen's cultivation strength enough, and after understanding the runes enough, he can further engrave and improve them on the basis of the original engraved runes.

This is also the practice method of ordinary Lingwu monks.

The runes engraved in their spirit palace were just a simulation of the real runes. This simulation is, of course, not complete. And the level of the monk is reflected in the degree of perfection of this simulation.

When, when a rune is completely simulated and all the mysteries of the rune are fully mastered, all dimensional space topologies are completely simulated, becoming a complete copy of the rune, and the rune at this time is called a "true rune" - it does not even need to be completely simulated, as long as the simulation degree reaches a certain level, the rune will automatically absorb the relevant power between heaven and earth, and naturally achieve the true rune.

It's as if uranium ore will automatically undergo a nuclear fission chain reaction as soon as it reaches a critical mass. This does not require human intervention, but is carried out automatically under the relevant laws of physics.

The process of automatic completion of the true talisman when the degree of rune simulation reaches a certain level is also known as the "low-dimensional holographic mapping of high-dimensional cosmic laws", referred to as "true talisman self-perfection".

Those who don't understand the runes well can only use them as bombs, just like humans who first mastered nuclear technology, and can't control the chain reaction. And once the level of understanding is sufficient, then it is like a human being who has mastered nuclear technology in depth, and can not only build nuclear weapons, but also slow down the chain reaction and create a nuclear power plant that can control nuclear reactions. There is not much difference in absolute destructive power, but in terms of the magic of the runes, it cannot be compared at all.

But even if you don't understand the rune well, once the real rune is achieved, its power and efficiency will still be many times stronger than before.

The rune that made Yang Chen ecstatic before, not only because he saw that the potential of this rune was extremely high, and the true dimension was extremely high, but more importantly, he obviously didn't understand this rune at all, but this rune still automatically showed the characteristics of its high-dimensional existence, which only meant one thing: this rune was likely to be a true rune. Only true talismans can have so many variations and infinite uses. That kind of spirituality, even the closest analog rune to the real rune is not possessed.

He has mastered a true talisman, such a good thing, Yang Chen almost dared not fantasize like this in the most daring dream.

It's just that, even in the later generations, there are still very few people who can really condense the true talisman. The only one is not a real great monk, but just a scientist who practices by the way, and whose main job is to do research!

It was the existence of this scientist that later generations mastered a key to unlock the mystery of the true rune: runic inequality.

Under the ingenuity of this scientist's genius, a large number of unknowns of the runes are approximated in a series of mathematical ways. And with the higher-order mathematical transformation of runic inequalities, even if you are completely ignorant of these unknowns, you can still get approximate results.

In the case of underdeveloped technology, even if this approximate result with a large error is still sufficient.

When the technology is not enough, many unknowns are not unknowns, but solvable calculations. At that time, the approximate accuracy of the calculation results of the runic inequality will naturally go to another level.

This repetition can be like a snowball, pushing the study of runes to a new peak.

With the runic inequality, the earth civilization has truly stepped on the door to crack the mystery of the true rune.

Even according to the grapevine, even the Trojans still salivate over this runic inequality mastered by the earthlings. Because different civilizations have different ways of thinking, even if they are also derived, they are definitely different. They are faced with the same runes, so if these different rune inequalities can be combined to derive a newer rune inequality, the effect will be many times more powerful than the previous two separate inequalities.

The importance of this runic inequality can be imagined. Even in later generations, the complete expression of this inequality was considered top secret. Also considered top secret is the name of the scientist who derived the runic inequality.

Even if Yang Chen, who was listed as a high-level member of the "Civilization Restart Plan", had mastered all the technologies that most Earth civilizations had mastered in later generations, he still didn't know the full expression of this runic inequality. Instead, there is only a derivation. As for incomplete expressions, they are made public. But this incomplete expression is just a tool for parsing runes, and if you want to deduce the runic inequality and its principles, you can't do it at all, you have to get a derivation method.

However, in order to ensure that secrets are not leaked, this derivation method can only be understood and applied by those who have really grown up in the atmosphere of earth civilization. In this way, even if a person like Yang Chen, who has mastered the method of deriving the runic inequality, is caught by the enemy and forcibly reads the memory, the other party will not be able to deduce this inequality. Because they have not grown up in the atmosphere of civilization on the earth, no matter how clever the technology is, as long as the essence of civilization has not exceeded the earth, then it is difficult to master the derivation method. When the essence of the other party's civilization surpasses that of the earth, the technology of this inequality is too low to be used.

In short, if the previous civilization of the earth, in the face of the mystery of the true symbol, it is like the human beings on the earth can see the light in the eyes of hundreds of thousands of light years or even more distant stars, but they are far away and can never reach it. Then the human civilization that has mastered the runic inequality is like the earthlings have a spaceship with the ability to jump in space and can instantly travel countless light-years away, and those stars that can only see the light but cannot touch before can now be observed and touched by the earthlings at any time.

In a sense, the infinite demand for computing power of later generations of monks is largely due to the runic inequality. According to incomplete statistics, except for low-level monks (below the sixth order of meteorites) who are completely unable to apply runic inequalities, the vast majority of monks have almost more than half of their computing power, which is used to analyze runes for incomplete expressions of runic inequalities.

For Yang Chen, he does not yet have the ability to deduce the complete expression of the rune inequality, but it is still possible to parse the rune with an incomplete expression.

It can even be said that the runic inequality and the current true rune are simply a perfect match!
