Xu Yi preached several things and could be easy to understand, start from small problems, lead to grandeur, and all his insights were revealed.

What's even more wonderful is that whenever someone asks questions, he will break them.

Even though the Biyou Academy is surrounded by the world, the lecture halls are popular, the gathering of talents, and various geniuses are everywhere, it is rare for those who have studied such a profound realm like Xu Yi.

After three or two classes, the preaching pavilion was completely overcrowded.

Xu Yi enjoyed this feeling very much. It was not the focus of everyone's attention, but the collision of knowledge sparks. While answering questions for others, there will always be new sparks of thinking.

Day after day, year after year, Xu Yi gradually got used to this kind of life.

With the preaching, the merit points in his talisman gathered rapidly, especially after a duel, the speed of the merit points gathered to a new climax.

The duel took place in the fourth lecture of the preaching pavilion. Wang Moke directly overturned the preaching pavilion with one sword, and Xu Yi had to face the battle.

Wang Moke, a powerful corpse-beheading man who became a corpse, had no power to challenge Xu Yi, but he had the power to cause trouble. Xu Yi could of course choose to ask the Council to intervene, but in that case, it would undoubtedly hurt his reputation and be unfavorable to preaching.

It was precisely because Wang Moke saw this that he directly lifted the roof of the sermon pavilion, and he knew that Xu Yi would definitely go to war.

Xu Yi really went to the battle.

In fact, Xu Yi was not surprised by Wang Moke's appearance.

He knew very well that when he stepped on the shoulders of the Five Hades of Kong Ming Island and jumped up, there would always be people who wanted to step on his shoulders and take advantage of the situation to fly.

Fame is a good thing, everyone wants it.

?Xu Yi dared to speak at the preaching pavilion, so he was mentally prepared to face the challenge.

The battle with Wang Moke has a great influence. He killed Wang Moke in a formation and completely confirmed the title of genius.

The career of teaching has become increasingly out of control since then.

In the afternoon of that day, the preaching pavilion was not absent, and Xu Yi talked about the thirty-six numbers of plum blossoms.

A crystal screen appeared in the void, and Xu Yi waved his hand to perform the method, and each formula was settled on the crystal screen.

When the wonderful things were spoken, everyone was fascinated by the audience. After the seventh number, there was a lot of cheers.

Xu Yi was about to take over the hall, and a guest at the hat suddenly stood up, "Mr. Xu, I have a question, I don't know if you may solve the problem."

Xu Yi said, "You can tell me the question. If you can solve it, I will give you the answer next time. You can pay the merit point. Now that get out of class is over, I have something to do."

“Let’s wait.”

The guest of the straw hat called Xu Yi, "My question is only a question, and it will be of great value. If you cannot solve it, wouldn't you listen to my question in vain? Another thing, if you can solve it, I will pay a black wish bead that can be used as a hundred meritorious points, but I ask Mr. Xu to read the question now and answer it immediately."

Xu Yi stared at the guest of the straw hat, "You can't trust me?"

The guest of the straw hat said, "Past lectures are not people who are not fooled by the world. I think Mr. Xu's age will not exceed a hundred, but his attainments in mathematics are even deeper than those of the monk who have accumulated hundreds of years. If someone behind Mr. Xu's backs, and the high theories he talks about every day and the difficulties he analyzes are all done by the masters behind him, then I will ask Mr. Xu for advice, wouldn't it be unfair?"

Xu Yi said secretly, "This is here to smash the situation."

While he pondered, there were already whispers in the field, and then he persuaded him to take the challenge.

Whether I really like him or want to try out what he is true or false, I am happy to watch the excitement.

"Since that's the case, please tell me the question."

Xu Yi waved his hand and the crystal screen reappeared.

In this matter, he had no room for retreat. At present, his situation was great and his merit points were accumulated rapidly. If this great situation continued, it would not take long before he could mature this talisman.

But all of this must be based on a good reputation.

He especially cannot let himself be infected with a bad reputation.

The same thing is said, it is difficult to be a public figure.

But the influence of public figures is what he urgently needs.

If he retreated, the hat guest would immediately fall into his reputation. No matter whether it is true or false, his influence would always be created.

What's more, Xu Yi has sufficient confidence in his attainments in mathematics.

Soon, the man in the hat fell on the crystal screen and suddenly, there was a burst of air in the field, and then, disturbances broke out.

"Absurd, this is not the topic at all."

"I think you are just here to make trouble. Is there such a problem in the world?"

"How can we find the volume area of ​​such an irregular sphere?"

"How about the circle cutting technique? How to cut the coordinates above carefully? Is there any possibility of finding a result?"

"Irregular curves cannot even list the equations, how do you need to find them?"

“…………”

Those who can listen to Xu Yi’s 36 numbers of plum blossoms in the preaching pavilion have profound attainments in the numbers.

At this moment, the Guest of the Tube Lai listed the question, and they all said they couldn't understand it, so the problem was naturally serious.

The guest of the straw hat looked at Xu Yi with a smile, "You also think this is not a question?"

What he listed on the crystal screen is a graphic question, with two coordinates vertically and horizontally, with clear scales and an irregular ellipsoid standing in the coordinates. The requirement of the question is to find the area of ​​this irregular ellipsoid.

?Xu Yi wanted to say that this was not a question, but a spark suddenly flashed through his mind and subconsciously said, "This is indeed a question, an excellent question."

It turned out that in an instant, Xu Yi's memories suddenly exploded, and he suddenly thought of his previous life.

In his previous life, he was not an excellent student and barely got into undergraduate studies.

He had never learned advanced mathematics much, but he had never learned it again and knew that the area of ​​such irregular ellipsoids could be found in his previous life.

What is coming, what is coming, by the way, calculus, yes calculus...

Speaking of which, Xu Yi in this world is definitely worthy of being a master of mathematics.

However, almost all he learned about the mathematical logic of this world, and the entire knowledge system was based on this ancient mathematical idea.

Even so, Xu Yi deeply understood the magnificence and vastness of mathematical knowledge.

In addition to technology, mathematics is also a philosophical idea. It is difficult for him to judge who has the best mathematics skills in this world or in his previous life, but he absolutely believes that the mathematical ideas he has received in this world are profound and transcendent.

"Mr. Xu, since you admit that this is a problem, please solve it."

The guest of the straw hat smiled.

Xu Yi said, "This question is a bit complicated, I need time to meditate..."

The guest of the straw hat was about to speak, but was interrupted by Xu Yi, "You don't have to worry about what kind of reinforcements I'm going to move. I'm meditating here. What restrictions do you need to make in terms of problem solving time?"

The guest of the straw hat wanted to say "of course", but he suddenly realized that all the people in Manting looked bad, and obviously they all made him intentionally make trouble.
