Xu Yi preached several times, able to explain the profound things in simple terms, starting from very small problems, leading to grand ones, and what he said were all insights.
What's even more wonderful is that whenever someone asks a question, he will immediately destroy it.
Even though the world outside Biyou Academy is full of lecture halls, gatherings of talents, and all kinds of talented scholars, there are very few people like Xu Yi who have reached such a high level of research in several ways.
After two or three classes, the mission booth was completely overcrowded.
Xu Yi enjoyed this feeling very much. It wasn't the attention of everyone, but the collision of knowledge sparks. While answering other people's questions, there would always be new sparks of thinking.
Day after day, year after year, Xu Yi gradually got used to this kind of life.
Along with the speech, the merit points in his lecture card were rapidly accumulating, especially after a duel, the accumulation speed of merit points reached a new climax.
That duel happened in the fourth lecture of the Mission Pavilion. Wang Moke directly overturned the Mission Pavilion with a single sword, and Xu Yi had to fight.
Wang Moke, the corpse-slaying powerhouse, did not have the right to challenge Xu Yi, but he has the right to make trouble. Of course Xu Yi can choose to ask the council to intervene, but that will undoubtedly damage his reputation. , is not conducive to preaching.
It was precisely this that Wang Moke was able to see, and he directly lifted the roof of the mission pavilion. He knew that Xu Yi would definitely fight.
Xu Yi really went out to fight.
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 tyrants of Kongming Island and jumped up, someone would always want to step on his shoulders and take advantage of the situation.
Fame is a good thing and everyone wants it.
Since Xu Yi dared to speak at the preaching booth, he was mentally prepared for the challenge.
The battle with Wang Moke had a lot of influence, and he killed Wang Moke, completely confirming his reputation as a genius.
Since then, the teaching career has become more and more out of hand.
In the afternoon of this day, all the seats in the preaching pavilion were absent, and Xu Yi gave a lecture on counting plum blossoms thirty-six.
A crystal screen appeared in the void, and Xu Yi waved his hand to perform the calculations, and each calculation was settled on the crystal screen.
When it came to the wonderful point, everyone was fascinated by it, and after the seventh number was finished, there was already a burst of applause.
Xu Yi was waiting for the hall to be closed when a man with a bamboo hat suddenly stood up, "Mr. Xu, I have a question. I don't know if you can answer it."
Xu Yidao, "You can tell me the problem. If you can solve it, I will answer it with you next time, and you can pay the merit point. get out of class is over now, and I have other things to deal with."
"Wait a minute."
The bamboo hat guest stopped Xu Yi, "My question, just the question itself, is of great value. If you can't solve it, why don't you just listen to my question. Another thing, if you can solve it, I will pay you a black wish." Zhu, 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 bucket hat guest, "Don't you trust me?"
The bamboo hat guest said, "In the past lectures, I was not a person who did not deceive the world. In my opinion, Mr. Xu's age may not be over a hundred, but his attainments in numeracy are deeper than that of monks who have accumulated hundreds of years. If there is someone behind Mr. Xu to help, and the high-level theories that he talks about every day and the problems he solves are all done by the expert behind him, then I am not wronged to ask Mr. Xu for advice?"
Xu Yi secretly said, "This is to spoil the situation."
While he pondered, there were whispers in the field, and then they all persuaded him to accept the challenge.
Whether you are really optimistic about him, or want to test his authenticity, you will be happy to watch the fun.
"Since that's the case, let's talk about it, Your Excellency."
Xu Yi waved his hand, and the crystal screen reappeared.
In this matter, he has no room to retreat. Right now, he is in a good situation, and his merit points are accumulating rapidly. If this good situation continues, he will be able to cultivate this card in a short time.
But all of this has to be based on a good reputation.
He especially couldn't allow himself to be stained with notoriety.
Again, it's not easy to be a public figure.
But the influence of public figures is what he urgently needs.
For the matter in front of him, if he quits, the hat maker will immediately put his notoriety on his own head. Whether it is true or not, the influence will always be created.
What's more, Xu Yi has sufficient confidence in his attainments in the way of numerology.
Soon, the man in the bamboo hat wrote down his question on the crystal screen. In an instant, there was a gasp in the room, and then there was commotion everywhere.
"Ridiculous, that's not the topic at all."
"I think your Excellency is here to make trouble. Is there such a problem in the world?"
"How can the volume and area of such an irregular sphere be calculated?"
"How about the circle cutting technique? How to cut the above coordinates in detail, is it possible to find the result?"
"Irregular curves, I can't even list the equations, how can I ask for it?"
"..."
Those who can listen to Xu Yi's narration of the thirty-six plum blossoms in the mission pavilion have profound attainments in numbering.
At this moment, the bucket hat guest listed the topic, but they all said they couldn't understand it, so the problem was naturally serious.
The bucket hat guest looked at Xu Yi with a smile, "Do you also think this is not a problem?"
What he listed on the crystal screen was a graphics problem, with two vertical and horizontal coordinates, with clear scales, and an irregular ellipsoid stood in the center of the coordinates. The requirement of the problem was to find the area of this irregular ellipsoid.
Xu Yi really wanted to say that this is not a problem, but a spark flashed in his mind, and he subconsciously said, "This is indeed a problem, an excellent problem."
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, so he barely passed his undergraduate degree.
He didn't learn advanced mathematics at all, but he never learned it again, and he also knew that there was a way to find the area of this irregular ellipsoid in his previous life.
What is that, what is it, by the way, calculus, yes calculus...
Speaking of which, Xu Yi in this world is definitely worthy of the title of master of numerology.
However, almost all of what he studied was the mathematical logic of this world, and the entire knowledge system was based on this ancient mathematical thought.
Even so, Xu Yi deeply understood the magnificence and vastness of mathematical knowledge.
Mathematics is not only a technology, but also a kind of philosophical thinking. He does not judge who has the highest mathematical skills in this world or the previous life, but he absolutely believes that the mathematical ideas he has received in this world are profound and detached.
"Mr. Xu, since you admit that this is a problem, let's solve it."
The bucket hat guest smiled.
Xu Yidao, "This topic is a bit complicated, I need time to meditate..."
The bamboo hat guest was about to speak, but was interrupted by Xu Yi, "You don't have to worry about me bringing in some reinforcements, I'll just meditate here, do you have any restrictions on the time you need to solve the problem?"
The bamboo hat guest was about to say "Of course", when he suddenly noticed that everyone in the pavilion looked unfriendly, obviously, they all thought he was deliberately causing trouble.
The bamboo hat guest said, "It's okay, I believe Mr. Xu's ability, he won't be untied for several days."
