It turns out that this secret book, to be precise, is not a skill secret book. At least in Xu Yi's view, this should not be attributed to a skill secret book, but a notebook and a proof. A warrior with profound knowledge of arithmetic has a strong influence on another person.

A certain idea put forward by a wise man, overturned and proved, and recorded in an essay.

The entire essay's discussion actually revolves around polygons and circles.

When he opened this secret book, he couldn't believe his eyes at first. He almost thought he had traveled back to the earth, otherwise he would never see someone discussing geometry in this world.

However, as soon as his thoughts changed, he came to his senses. Circles and geometry were not profound knowledge. In another time and space, the ancients thousands of years ago were also studying them.

Xu Yi would certainly not be interested in just discussing geometry. Although he had received so-called higher education in another time and space, he had long since lost interest in book knowledge.

The reason why this book aroused Xu Yi's strong interest was because at the end, the wise man proposed the possibility of integrating learning with martial arts.

The book mentions that a great mathematician named Sui put forward 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 compasses.

The implication is that other regular polygons cannot be made with rulers and gauges.

In response to this conjecture, the wise man came up with the conjecture of a regular heptagonal ruler and compass, and used more than ten pages to confirm this conjecture.

Which warrior would study such profound arithmetic knowledge?

Xu Yi studied martial arts for more than two years and had never heard of it.

Even though he listened to Master Zhou talking about martial arts in the world, he never heard Master Zhou say that he had a lineage of arithmetic.

When such a secret book appeared in the world, people who didn't understand it naturally talked about it, and there were only a few people who knew it. Even Xu Yi would definitely turn this secret book into a ghost painting if he had not had the knowledge in his previous life.

Even with the arithmetic knowledge from his previous life, Xu Yi still had to spend a lot of effort to fully understand this discussion.

Thanks to the enhanced strength of his soul, his intelligence is far higher than in his previous life.

Otherwise, even if a wise man gives a detailed proof, he will not be able to understand it.

During this long period of time, Xu Yi not only understood the discussion in the book, but also followed the explanations in the book and used rules and regulations to forge the regular heptagon.

After this drawing, there were dozens of pieces of paper. Even though he had advanced in cultivation now, his eyes were red.

Time passed bit by bit, Xu Yi was still hunkering down at his desk and drawing, and the faint halo of light emitted by the pearl in the corner stretched his figure extremely long.

After finishing the last piece of paper, he squatted on the ground and drew until half of the room was filled with ink lines. With a click, the ink pen was stabbed hard on the ground and broke into two parts.

Xu Yi jumped up and hit his head heavily on the top of the wall. He didn't feel any pain at all, he raised his neck and laughed desperately, causing the clear water in the cauldron to ripple in circles.

He drew it!

A most standard regular heptagon!

Just use a ruler!

At this moment, there is no one on the empty mountain, and the water is flowing and the flowers are blooming.

For him, this moment felt like eternity!

After laughing for a long time, Xu Yi swayed and stood in the center of the room. He spread out his body and saw streaks of light and shadow wandering around the room, filling the room with wind.

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

If Xu Yi's movements were nimble in the past, then Xu Yi's movements now are fleeting.

I don’t know where it starts, and I don’t know where it ends.

The moment he settled down, the floor of the room was already filled with densely packed circles one after another, large or small.

This secret book is here to be practiced!

It sounds fast, but in fact it is extremely difficult. This technique is extraordinary. Other techniques either focus on the support of drugs or the changes in moves and the transformation of traditional and simple techniques.

Therefore, when practicing, most of the water grinding techniques are needed and polished over time.

Strictly speaking, this body technique is a derivative of arithmetic, just like one plus one gets two. Once you understand the principle, you will be able to do it.

Just like this secret book, there are fifteen pages in total, and the first fourteen pages are all about rulers and gauges to obtain shapes. It is not until the end of the fifteenth page that the wise man elaborates on the idea of ​​using circles into martial arts.

Xu Yi understood the first fourteen pages, but the fifteenth page became incomprehensible.

Perhaps the wise man's attention was never on martial arts, so in the end, he didn't even record the name of this set of movements.

This is also the biggest reason why countless buyers at Suishifang did not regard this book as a secret book of exercises.

Xu Yi slowly walked around the room, thinking in his mind, "The essence of this body method is to seek the beauty of the circle. Within a circle, a flash of thought can arrive, and the land of a circle can be transformed into a square inch. In fact, you can return to the original state."

It’s so wonderful, why not call it Guiyuan Step.”

After deciding on the name, Xu Yi had no reason to stay here for a long time. He checked his waist bag carefully and found that everything was in good condition.

house.

The moment I opened the door, I felt a cool breeze blowing on my face, carrying the scent of flowers. I could see the sky, the sun was setting in the west, and the tired birds were returning. It was evening again.

Xu Yi was inexplicably horrified and quickly took out the jade crystal number plate and printed it on the black disc in the center of the door. The light flashed and a six character appeared on it.

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

What's even more scary is that, including the day of pretending to be sick at home, tomorrow is the day of the battle. If we delay for another day, we will miss the decisive battle.

Xu Yi didn't dare to delay, so he walked out. Unexpectedly, before he had taken two steps, there was a clang of a gong and a loud shout, "The man in the hat is coming out!"

Suddenly, hundreds of people came from all directions like groundhogs, jumping over from nowhere and quickly surrounding Xu Yi.

The leader was none other than Mr. Lei Ye, a man in Tsing Yi who was thrown away by Xu Yi in the cafeteria that day and hit hard on the ground.

It turned out that that day, Mr. Lei led a group of people from the Heroes Association to show off their power in the cafeteria, and ended up kicking Xu Yi on the iron plate, almost breaking his toes.

In full view of the public, a self-proclaimed hero would suffer such a big loss and suffer such a big loss, how could he give up?

So, after everyone from the Heroes Association had discussed it, they decided to get back on their feet.

Unexpectedly, Xu Yi turned around and went into the practice room to retreat. This retreat lasted for two days and two nights.

The Heroes Association had no choice but to use clumsy methods. Fortunately, they found the number of Xu Yi's training room and sent people to wait here.

Only then did the current scene happen.

Seeing being surrounded by people, Xu Yi strode forward without twitching his eyelids.

With his move, the encirclement immediately loosened. The impression he left that day was too strong.
Chapter completed!
