Xu Yi preached a number of things, and was able to explain things in a simple and profound way, starting from very small problems and leading to big things, and all of them were true insights.
What's even better is that whenever anyone asks a question, he will answer it without hesitation.
Even though in the outer world of the Biyou Academy, various lecture halls are popular, talents gather, and all kinds of genius scholars appear and disappear, but those like Xu Yi who have reached such a profound level in the study of numbers are rare.
After three or two classes, Preaching Pavilion was completely overcrowded.
Xu Yi really enjoys this feeling. It is not the spotlight, but the collision of sparks of knowledge. While solving problems 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.
As he preached, the merit points on his lecture card were gathering rapidly. Especially after experiencing a duel, the speed of gathering merit points reached a new climax.
That duel took place in the fourth lecture of the Preaching Pavilion. Wang Moke directly overturned Preaching Pavilion with a sword, and Xu Yi had to fight.
Wang Moke, the corpse-killing master who turned into a corpse, 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 a harm to his reputation and not conducive to publicity.
Wang Moke saw exactly this and blew away the roof of the Preaching Pavilion's pavilion. He knew that Xu Yi would definitely fight.
Xu Yi really went to battle.
In fact, Xu Yi is not surprised at all by the appearance of Wang Moke.
He knew very well that when he stepped on Five Tyrants of Kongming Island's shoulders and jumped up, there would always be someone who wanted to step on his shoulders and take advantage of the situation and fly away.
Fame is a good thing, everyone wants it.
Since Xu Yi dared to give a lecture at the Preaching Pavilion, 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, all Preaching Pavilion seats were absent, and Xu Yi talked about the number of plum blossoms Thirty-Six.
A crystal screen emerged in the void. Xu Yi waved his hand and performed the calculations one by one on the crystal screen.
When he talked about the wonderful points, 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 Hat Man suddenly stood up and said, "Mr. Xu, I have a question. I wonder if sir can answer it."
Xu Yi said, "You can ask me your question. If you can solve it, I will give you the answer next time and you will just pay the merit points. get out of class is over now, and I have other things to deal with."
"Wait a minute."
Hat Man called out to Xu Yi, "My question, just the question itself, is of extraordinary value. If you can't solve it, why don't you just listen to my question in vain? And another one, if you can solve it, I will pay you a black wish bead, which 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 Hat Man, "Can't you trust me?"
Hat Man said, "In the past lectures, he was not a person who deceived the world and stole his reputation. I think Mr. Xu is not over a hundred years old, but his attainments in numeracy are better than those of monks who have accumulated hundreds of years. It also needs to be profound. If there is someone behind Mr. Xu who can give advice, and the high-level talks and difficult problems he talks about every day are all done by the experts behind him, then wouldn't it be unfair for me to ask Mr. Xu for advice?"
Xu Yi said secretly, "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 Hat Man to test whether he is real or fake, 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, Hat Man will immediately get a bad reputation on his head. 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, Hat Man dropped 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 to cut the above coordinates in detail? Is it possible to find the result?"
"Irregular curves, and even the equation can't be listed. How can I find it?"
"..."
Anyone who can listen to Xu Yi talking about the number of plum blossoms Thirty-Six in the Preaching Pavilion has profound attainments in the number path.
At this moment, Hat Man listed the questions, and they all complained that they could not understand them. The problem was naturally serious.
Hat Man 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 get through as an undergraduate.
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 named among the masters of numerology.
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 we admit that this is a question, let's solve it."
Hat Man said with a smile.
Xu Yi said, "This question is a bit complicated. I need time to meditate..."
Hat Man was about to speak, but was interrupted by Xu Yi, "You don't have to worry about me bringing in any reinforcements. I'll just meditate here. Do you need to put any restrictions on the problem-solving time?"
Hat Man was just about to say "Of course" when he suddenly realized that everyone in the pavilion had a bad look on his face. Apparently, they all thought he was deliberately causing trouble.
Hat Man said, "It doesn't matter, I believe that Mr. Xu's ability will not last for several days."
