Riemannian geometry, on the earth, was proposed by the German Göttingen School mathematician Riemann. This is an extension of Euclid's fifth axiom and a generalization of Euclidean plane geometry.

Because of the mysterious correspondence between the two worlds, or simply the evil taste of a certain heavenly way, this kind of geometry with positive curvature can still be called "Riemannian geometry" or "Riemannian geometry" in China. The monk of the Ten Thousand Laws Gate, the curved heavenly demon Riemann relied on this geometry to achieve enlightenment.

Riemannian geometry is the mathematical basis of general relativity and is used to describe the space-time model of general relativity. "The essence of gravity is the curvature of space-time", and this "bending" is the curvature of Riemannian geometry.

Therefore, Ai Changyuan also geometrically transformed Riemann into the Heaven Collapse Palm, so that he could master this anti-heaven killing move during the Qi training period.

Wang Qi was not a little sure of winning against Ai Changyuan, but after watching yesterday's fight, he found his chance to win.

"It's very good that you use Riemann geometry and transform Riemann geometry into the Collapse Heaven Palm, which not only reduces the difficulty of this martial art, but also strengthens its power—but this also makes you have to rely on rubbing pills to make moves!"

Vientiane Tianyin transforms into a true form of gravity, formless and phaseless, and extremely difficult to deal with. If nothing else, the ability to directly interfere with blood flow alone should not be underestimated. "Whim" is a high interest as an adjective, but as a verb or noun without modification, it will only kill people.

Since Vientiane Tianyin did not practice qi at all, it was not included in the Immortal Temple. The Crack Peak Ai family is the descendant of the Venerable Yuan Li, and this miracle can be learned at home. Without knowing the mental method, it is difficult for Wang Qi to peek into the flaws.

But Riemannian geometry is traceable! especially if someone has been good at it in their last life.

"So, what I have to do now is to integrate Riemannian geometry into my knife technique - I don't need to create my own set of knife techniques that are completely rooted in Riemannian geometry, I just need to integrate the arithmetic of this geometry with my knife skills!"

What Wang Qi has to do now is not to create another sword method, but to add a few points of Riemannian geometry arithmetic on the basis of Bai Ze's true array slash and thunder sound chord knife method.

Riemannian geometry is closely related to differential manifolds, partial differential equations, and multiple complex functions. And the Thunder Yin Chord Knife Technique and Bai Ze True Array Slash are also martial arts derived from calculus. Wang Qi hadn't thought of this sword technique before, just because he failed to incorporate the most important concepts of calculus, such as "limit" and "infinity", into martial arts.

The more basic the concept, the more difficult it is to apply it in a more advanced way. Originally, it would take a few months to a few years for Wang Qi to get to this point, but the accident a few days ago saved Wang Qi from these hard labors.

Lingbao fractal diagram, this mysterious figure fixed in Wang Qi's soul, also contains the mystery of "infinity". In the three days that Wang Qi calmed down his demons, he also touched on some of the mysteries of fractal diagrams. This led him to find a way to incorporate calculus into his swordsmanship.

Of course, this is only the way to go. Wang Qi is still a long way from entering the Olympics. But even so, he is already too far ahead of ordinary people who can't get in.

While Wang Qi was struggling to calculate a set of knife techniques that could break the Heavenly Palm, Ai Changyuan was also doing similar things. He was thinking about the elephant phase wave gong and the breaking method of the heavenly entropy technique.

This boy was honest in his study. Unlike Wang Qi, Ai Changyuan is proud and proud, but he has always been a model of the lion fighting the rabbit and doing his best - what is more valuable is that he never dies. At this point, some little master of death should indeed learn from him.

The cultivators of Venerable Yuanli's time had a strong attachment to the theory of cause and effect. The Crack Peak Ai family retains the atmosphere of that era. Under the influence of his ears and eyes from childhood to adulthood, Ai Changyuan was convinced of a famous saying of Bai Ze Shenjun - the victory or defeat of the monk's fighting method had already been decided before the battle.

After the ethereal path of the ethereal palace, the determinism was shaken to a certain extent, and many monks began to discuss meaningless questions such as "will a meteorite suddenly fly over and kill me and my opponent when you are ready to stand in the middle of your feet", and then conclude that "the outcome of the battle is probabilistic". But Ai Changyuan never believed this. He's always been as prepared as he can be.

At this time, the winter solstice had just passed, and the days were not long, and it was not long before it entered the night. Lu Chichiyo, who stayed with Ai Changyuan, activated the lighting magic seal in the room. Seeing her friend's frowns, she was a little worried, and asked, "Changyuan Changyuan, is the enemy very tricky this time?"

Ai Changyuan nodded: "It's true." It's hard for me to think of a foolish way to beat him. The only thing that comes to mind now is to avoid melee combat as much as possible. ”

Lu Qianqian was taken aback: "Why, Changyuan, your fist and foot kung fu is obviously so strong!"

"It's not about the fists and feet, it's about the mind. Ai Changyuan put down the pen in his hand and asked, "Do you remember his first competition?"

Lu Qianqian hurriedly nodded: "Remember, Kunzhong Xuan!"

"He just used his fist lightly, and Kun Zhongxuan's 'crustal qi' automatically collapsed from the inside. This is the viciousness of the Heavenly Entropy Formula. If it is attacked by the entropy increase force, it will stagnate internally, or go mad into the demon body and die—of course, the most common way to die is spontaneous combustion and rainbow. Ai Changyuan said: "I attack strong and defend weak, if it is disrupted, it will be very bad." ”

Lu Qianqian blinked: "Then you are using Vientiane Heaven to attract the opponent's blood from a long distance?"

"I've never played against a practitioner of the Elephant Wave Gong, so I don't know what's so subtle about this practice. However, since it is a phase wave, it should also have the ability to disturb gravity. ”

"Do you want to use the Heavenly Palm as soon as you start?"

"I have that idea, but I have to think about it again. Ai Changyuan closed his eyes and nodded his head: "And you can't ignore his attainments in knife skills." ”

That guy is actually the same type of attack as me, so can you use a round of strong attack to win it directly...... No, "guarding the weak" is only relatively speaking, and the whole body is protected by phase waves...... I haven't seen anyone break the defense yet......

Looking at Ai Changyuan, who was thinking seriously, Lu Qianqian suddenly felt full of confidence: "Anyway, Changyuan, you are the best!

Ai Changyuan smiled and patted the girl's head, but his thoughts drifted away.

Tomorrow...... You won't let me down.
