It turns out that this secret book is not a secret book of martial arts. At least in Xu Yi's opinion, it should not be attributed to a secret book of martial arts, but a note, a proof, a warrior with advanced math knowledge, overturned and proof of some idea proposed by another wise man, and recorded an essay.

The whole essay actually revolves around polygons and circles.

When he opened this secret book, he couldn't believe his eyes at first, almost thinking that he had penetrated back to the earth, otherwise he would have seen someone discussing geometry in this world.

However, when his thoughts changed, he realized that circles and geometry were not very profound knowledge. Another time and space, the ancients thousands of years ago were also studying it.

If he were just discussing geometry, Xu Yi was of course not interested. Although he had received the so-called higher education in another time and space, he had long been interested in the knowledge in books.

The reason why this book made Xu Yi have a strong interest was that at the end, the wise man proposed the possibility of incestuous martial arts.

The book mentions that a great calculator named Sui proposed an interesting theory.

Regular triangles, regular quadrilaterals, regular pentagons, regular pentagons, and polygons with twice the number of sides mentioned above can be made directly with rulers and gauges.

The implication is that regular polygons other than this cannot be made with rulers or standards.

The wise man responded to this conjecture, put forward the conjecture of the ruled plaque of the regular heptagram, and used more than ten pages of content to confirm this conjecture.

With such a profound knowledge of mathematics, who can do a martial artist to study it carefully?

Xu Yi has been practicing martial arts for more than two years, but has never heard of it.

Even though he heard Master Zhou talk about martial arts in the world, he never heard Master Zhou say that there is a lineage of calculation.

If such a secret book appears in the world, naturally people cannot understand it and few people can understand it. Even if Xu Yi had not had the knowledge of his previous life, he would have definitely used this secret book as a ghost painting talisman.

Even if you have knowledge of mathematics from your previous life, Xu Yi will take a lot of effort to fully understand this discussion.

Fortunately, his soul strength has increased and his intelligence is much higher than his previous life.

Otherwise, even if the wise man gave a detailed proof, he would not understand it.

During this long period of time, Xu Yi was not only understanding the arguments in the book, but also using rules and regulations to draw cats and forge the regular seventeen-sided shape according to the explanations in the book.

After this painting, there were dozens of pieces of paper. Even though he had already achieved great success, his eyes were red.

Time passed by bit by bit, and Xu Yi was still at his desk to make pictures. The faint halo of the pearls in the corner of the wall pulled his figure very long.

After finishing the last piece of paper, he squatted on the ground to draw, drawing half of the room, full of ink threads. With a click, the ink pen was poked heavily on the ground by him and broke into two pieces.

Xu Yi jumped up and his head hit the top of the wall. He felt no pain at all. He raised his neck and laughed desperately, shaking the clear water in the cauldron and rippled in circles.

He drew it!

The most standard regular heptadec-shaped shape!

Only use ruler!

At this moment, there was no one in the empty mountains and the water flowed and flowers bloomed.

This moment, for him, waited for eternity!

After laughing for a long time, Xu Yi shook his body and stood in the middle of the room. His body unfolded, and he saw lights and shadows wandering indoors, and the room was filled with wind.

At this moment, he was in the corner of the west wall, and the next moment, his figure appeared in the south.

If Xu Yi's body movements were light and quick in the past, then Xu Yi is now floating.

I don’t know where to start, but I don’t know how to stop.

The moment the body settled, the floor of the room was filled with dense circles, one after another, big or small.

This secret book is practiced here!

It is actually extremely difficult to say that it is fast, and this technique is extraordinary. The other technique either emphasizes drug support, or emphasizes changes in moves and transformations in traditional and simple ways.

Therefore, when practicing, you need to practice water grinding techniques and rely on time to polish them.

Strictly speaking, this set of body techniques is a derivative of mathematics, just like one plus one to two. Once you understand the principles, you will know it.

As for this secret book, there are a total of fifteen pages, and the first fourteen pages, all discuss the ruler and the shape is obtained. It is not until the end of the fifteenth page that the wise man explained the idea of ​​using round into martial arts.

Xu Yi understood the first fourteen pages, but the fifteenth page was unreadable.

Perhaps the wise man's attention has never been better than martial arts, so at the end, even the name of this set of body techniques has not been recorded.

This is also the biggest reason why countless buyers did not regard this book as a secret book in Suiyifang at all.

Xu Yi slowly walked around the room and thought to himself, "The key to this body method is to seek the wonder of the roundness. Within a circle, a flash of thought will arrive. To transform the land of the roundness into a square inch, you can actually get the wonder of the return of the Yuan. It is better to call the return of the Yuan step."

After deciding his name, Xu Yi had no reason to stay here for a long time. He carefully checked his waist bag and everything was missing. He wrapped his waist bag on his body, put it on a hat, and went up the steps. Before long, he left the practice room.

The moment I opened the door, the breeze blew on my face, mixed with the fragrance of flowers, and I looked at the sky, the setting sun, and the tired birds returned, and it was another evening.

Xu Yi was inexplicably terrified and hurriedly took out the jade crystal sign and printed it on the black disc in the center of the gate. The light flashed, and a six-character appeared on it.

Xu Yi was shocked. He never thought that just drawing circles would take him two days and two nights.

What I was even more afraid of is that if I included the day when I was sick at home, tomorrow would be the time to make an appointment. If I delayed another day, wouldn’t I have missed the decisive battle?

Xu Yi did not dare to delay and could do it. However, he didn't know that he had not taken two steps. A clang gong sounded and a wild shout, "The man from the hat is coming out!"

In an instant, hundreds of people from all directions rushed over like marmots, and quickly surrounded Xu Yi.

The leader was the man in Qing Ye, who was thrown away by Xu Yi and smashed him to the ground on that day.

It turned out that day, Lei Ye led a group of people from the Heroes Club to show off his power in the cafeteria, but he kicked Xu Yi's iron plate, which was like a broken toe.

In front of everyone, a hero who claims to be extraordinary will suffer such a great loss and suffer such a big loss, how can he give up?

So, after the discussion was over, the heroes decided to find the place.

I didn't know that Xu Yi turned around and went into the practice room and went into seclusion. This seclusion lasted for two days and two nights.

He had no choice but to use stupid methods. Fortunately, he found Xu Yi's training room number and sent someone to wait here for the rabbit.

This is where the current scene comes.

Seeing that he was surrounded by everyone, Xu Yi didn't twitch his eyelids and walked with big strides.
Chapter completed!
