Chapter 2453 Irregular

Xu Yi preached a number of things, and he was able to explain the profound things in a simple way, starting from very small problems and leading to big things, and all of them were true knowledge and insights.

What's even better is that whenever anyone asks a question, he just answers it.

Even though in the world outside Biyou Academy, various lecture halls are popular, talents gather, and all kinds of genius scholars appear and disappear, there are very few people like Xu Yi who have reached such a profound level in Shudao.

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

Xu Yi enjoys this feeling, not being the center of attention, but the collision of sparks of knowledge. While answering questions for others, new sparks of thinking will always emerge.

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

As he preached, the merit points on his lecture card were gathering at a rapid pace. Especially after a duel, the speed of gathering merit points reached 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 fight.

The corpse-killing master Wang Moke originally had no power to challenge Xu Yi, but he had the power to cause trouble. Of course Xu Yi could choose to ask the council to intervene, but that would undoubtedly be harmful to his reputation. , which is not conducive to publicity.

Wang Moke saw exactly this and flew off the roof of the preaching pavilion. He knew that Xu Yi would definitely fight.

As expected, Xu Yi went to battle.

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

He knew very well that when he stepped on the shoulders of the five tyrants of Kongming Island and jumped up, there would always be someone who wanted to step on his shoulders and take advantage of the situation to fly away.

Fame is a good thing, everyone wants it.

Since Xu Yi dared to give a lecture in the preaching booth, he was mentally prepared for the challenge.

The battle with Wang Moke had a huge influence. He killed Wang Moke in a formation, completely confirming his reputation as a genius.

Since then, his teaching career has become more and more out of control.

In the afternoon of this day, everyone in the sermon pavilion was absent, and Xu Yi gave a lecture on the thirty-six number of plum blossoms.

A crystal screen appeared in the void. Xu Yi waved his hand and performed the calculations one by one, and then settled on the crystal screen.

When he came to the wonderful point, everyone was fascinated by it. After the seventh number, the whole hall was filled with cheers.

Xu Yi was about to leave the hall when a guest in a bamboo hat suddenly stood up and said, "Mr. Xu, I have a question. I wonder if you can answer it."

Xu Yi said, "You can ask me your question. If you can solve it, I will answer it with you next time and you will pay the merit points. get out of class is over now, and I have other things to deal with."

"Wait a minute."

The man in the hat stopped Xu Yi and said, "My question, just the question itself, is of extraordinary value. If you can't solve it, why don't you listen to my question in vain? And another one, if you can solve it, I will pay you a black wish." Pearls can be used as more than a hundred merit points, but I ask Mr. Xu to read the question now and answer it immediately."

Xu Yi stared at the man in a bamboo hat, "Can't you trust me?"

The guest in Dou Li said, "In the past lectures, he was not a person who was able to deceive the world and steal his reputation. I believe that Mr. Xu is not over a hundred years old, but his attainments in mathematics are deeper than those of the monks who have accumulated hundreds of years of experience. If there is someone behind Mr. Xu’s back, and the high-level talks and difficult questions he talks about every day are all done by the master behind him, then wouldn’t it be unfair for me to come to ask Mr. Xu for advice?”

Xu Yi secretly said, "This is here to cause trouble."

While he was pondering, there were already whispers in the audience, and then they persuaded him to accept the challenge.

Whether you are really optimistic about him or want to test his authenticity, you are all happy to watch the excitement.

"In that case, please state the topic."

Xu Yi waved his hand and the crystal screen reappeared.

In this matter, he has no room to retreat. He is in a good situation right now, and his merit points are accumulating rapidly. If this good situation continues, it won't take long for him to master this skill.

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

He especially couldn't allow himself to gain notoriety.

As the saying goes, it’s not easy to be a public figure.

But the influence of a public figure is what he urgently needs.

As for the matter in front of him, if he retreats, the hater will immediately put a bad name on himself. Regardless of whether it is true or false, the influence will always be created.

What's more, Xu Yi has full confidence in his attainments in numerology.

Soon, the man in the bamboo hat wrote down his question on the crystal screen. Suddenly, there was a sound of gasping in the room, and then there was a commotion.

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

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

"How can the volume and area of ​​such an irregular sphere be calculated?"

"How about cutting a circle? How can we cut the coordinates above in detail? Is it possible to find the result?"

"Irregular curves, and I can't even formulate an equation. How can I ask for it?"

"…………"

Those who can listen to Xu Yi's talk about the thirty-six numbers of plum blossoms in the preaching pavilion have profound attainments in number.

At this moment, the man in the hat listed the questions, and they all complained that they could not understand. The problem was naturally serious.

The man in a hat looked at Xu Yi with a smile, "You also think this is not a problem?"

What he listed on the crystal screen was a graph question, with vertical and horizontal coordinates and clear scales. An irregular ellipsoid stood in the coordinates. The requirement of the question was to find the area of ​​this irregular ellipsoid.

Xu Yi wanted to say that this was not a question, but a spark suddenly flashed in his mind and he 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 past life.

In his previous life, he was not an outstanding student and barely managed to pass the undergraduate program.

He had never studied advanced mathematics at all, but he had never studied it again, and he knew that the area of ​​such an irregular ellipsoid could be found in his previous life.

What is that, what is that, right, calculus, yes calculus...

Speaking of which, Xu Yi in this world definitely deserves to be called a master of mathematics.

However, what he studied was almost all the mathematical logic of this world, and the entire knowledge system was based on this ancient mathematical thought.

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

Mathematics is not only a technology, but also a kind of philosophical thought. It is difficult for him to judge who has higher mathematical skills in this world or in the 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 question, let's solve it."

The man in a hat said with a smile.

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

Just when the man in the hat was about to speak, he was interrupted by Xu Yi, "You don't have to worry about me bringing in reinforcements. I'll just meditate here. Do you need to put any restrictions on the time for solving problems?"

Just when the man in the hat wanted to say "Of course", he suddenly realized that everyone in the pavilion looked evil. Apparently, they all thought that he was deliberately causing trouble.

The guest in the hat said, "It doesn't matter, I believe Mr. Xu's ability will not last for several days."
