I Came From The Mortal World

Chapter 69 On the Circle
It turns out that this secret book, to be precise, is not a secret book of martial arts, at least in Xu Yi's view, it should not be attributed to a secret book of martial arts, but a notebook, a proof, a martial artist with advanced arithmetic knowledge, and another A certain idea put forward by a wise man, the overthrow and proof made, and a book of essays recorded.

And the discussion of the whole essay revolves around polygons and circles.

When he opened this secret book, at first, he couldn't believe his eyes, he almost thought that he had traveled back to the earth again, otherwise he would see someone discussing geometry in this world.

However, after thinking about it for a while, he came to his senses.Circles and geometry are not so profound knowledge, another time and space, the ancients thousands of years ago are also studying.

Of course, Xu Yi is not interested in discussing geometry. Although he has received so-called higher education in another time and space, he has long lost interest in book knowledge.

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

It is mentioned in the book that a great calculator surnamed 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 directly made with rulers and rules.

The implication is that other regular polygons cannot be made with rulers or rules.

In response to this conjecture, the wise man proposed a conjecture on the construction of a regular seventeen-sided ruler and compass, and used more than ten pages of content to prove this conjecture.

With such a profound knowledge of arithmetic, which warrior would study it intensively?
Xu Yi has practiced martial arts for more than two years, but he has never heard of it.

Even if he listened to Master Zhou talking about the world's martial arts, he never heard Master Zhou say that there is a lineage of arithmetic.

With such a secret book appearing in the world, people who don't understand it will talk about it, and there are very few people who know it. Even Xu Yi, if he didn't have the knowledge of his previous life, would definitely use this secret book as a ghost drawing talisman.

Even with the knowledge of mathematics in his previous life, it would take Xu Yi a lot of mental effort to fully understand this exposition.

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

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

During this long time, apart from understanding the exposition in the book, Xu Yi was actually following the explanation in the book, using rules and regulations to forge this regular seventeen-sided shape.

After this painting, there will be dozens of sheets of paper, even though his cultivation is advanced now, his eyes are red from the heat.

As time passed bit by bit, Xu Yi was still drawing at his desk, and the faint halo from the pearl in the corner stretched his figure extremely long.

After drawing on 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 poked hard on the ground by him and broke in two.

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

He drew it!
A most standard regular heptagon!

Just use a ruler!

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

This moment, to him, waited like eternity!
Laughing for a long time, Xu Yi's figure flickered, and he stood in the center of the room. His figure spread out, and he saw streaks of light and shadows wandering around the room, filling the room with wind.

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

If it is said that Xu Yi's agility in the past was light and agile, then Xu Yi is now floating.

I don't know where to start, and I don't know where to stop.

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

This secret book is here to practice!
It sounds quick, but in fact it is extremely difficult. This exercise is unusual, and the other exercises either pay attention to the strengthening of medicine, or the change of moves, and the transformation from simple to complex.

Therefore, when practicing, it is necessary to grind the skills with water and rely on time to polish them.

And this set of movements, strictly speaking, 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 a total of fifteen pages, the first fourteen pages are all about rulers and gauges to get shape, and it was not until the end of fifteen pages that the wise man expounded the idea of ​​using circles into martial arts.

Xu Yi understood the first fourteen pages, but the No. 15 page was completely incomprehensible.

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

This is also the biggest reason why countless buyers did not regard this book as a secret book of exercises in Shuranfang back then.

Xu Yi walked around the room slowly, thinking in his mind, "The main purpose of this body technique is to seek the perfect circle. Within a circle, you can reach it in a blink of an eye. If you turn a circle into a square inch, you can really return to the original place." It’s so wonderful, why not call it Guiyuanbu.”

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 intact, so he wrapped his waist bag around his upper body again, put on a bamboo hat, and went up the stairs. After a while, he went out to practice kung fu house.

The moment the door was opened, the breeze was blowing, mixed with the tangy fragrance of flowers, the sky was as far as the eye could see, the sun was setting, and the tired birds were returning. It was another evening.

Xu Yi was inexplicably terrified, and hurriedly took out the Yujing number plate, 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 taken aback. He never imagined that it took two days and two nights just to draw a circle.

What is even more frightening is that, counting the day of pretending to be sick at home, tomorrow is the time for a battle. If you delay for another day, you will miss the decisive battle.

Xu Yi didn't dare to delay, so he just started, but he didn't know that before he took two steps, there was a sound of a gong, and he heard a wild shout, "The bamboo hat man has come out!"

In an instant, hundreds of people from all directions, like groundhogs, jumped up from nowhere and quickly surrounded Xu Yi.

The leader was Lei Ye, the man in Tsing Yi who was thrown flying by Xu Yi in the cafeteria that day and fell to the ground hard.

It turned out that Lord Lei led a group of people from the Hero Club to show off in the cafeteria that day, but he kicked Xu Yi on the iron plate, almost breaking his toe.

Under the watchful eyes of everyone, the self-proclaimed hero will suffer such a big loss and face such a big face, how can he give up.

So, after everyone in the Hero Club had a discussion, they decided to get back on the stage.

Unexpectedly, Xu Yi turned around and went into the practice room, and retreated. This retreat lasted a full two days and two nights.

The Hero Club had no choice but to use a stupid method. Fortunately, after finding out the number of Xu Yi's practice room, they sent someone to wait there.

This is how the present scene came about.

Seeing being surrounded by the crowd, Xu Yi strode forward without blinking an eyelid.

When he moved, the encirclement immediately loosened. That day - the impression he left was too strong.
