Without giving the new classmates or old classmates much time to chat, Lan Jie almost followed a few of them into the classroom.

The first time he saw Qiao Yu, Lan Jie couldn't help but raise the corners of his mouth slightly. Today he came to the classroom five minutes early just to see if this kid was here. Now that he saw it, he felt at ease.

"Ahem, everyone hasn't arrived yet, but I'd like to introduce it to you first. Today we have a new student in the Olympiad class, Qiao Yu. Although Qiao is from the junior high school, he has a very high level of mathematics. If you have any If you don’t understand anything, you can find an opportunity to ask him for advice. Of course, he is younger than you, and I hope you can help Qiao Yu more in life."

Although considering that saying this in class might undermine the confidence of many students in the Olympiad class, Lang Jie decided to give these high school children a thorough explanation first.

Just like the classic line in Zhou Xingxing's movie, a stylish man, no matter where he is, is like a firefly in the dark, so obvious and outstanding...

In fact, the same is true for mathematics. After all, you also need to undergo various training and examinations.

Those who can enter the Olympiad class must have an IQ above the average. After a few classes, everyone will be able to figure out their respective levels.

Instead of being hit when the time comes, it is better to give these arrogant and arrogant people a clear explanation now.

Everyone in the classroom focused their attention on Qiao Yu, and most of them looked unconvinced.

Of course this is normal.

Sixteen or seven years old is the age when you are arrogant and arrogant. If you are selected into the Olympiad class, you are the best in mathematics in the class. You can get full marks in the exams without any accidents. How can you accept a junior high school student in mathematics? The level is higher than them?

Fortunately, Qiao Yu has become accustomed to being watched by people in the past two days. So even if all the eyes are focused on him, it doesn't feel uncomfortable.

On the contrary, he was in a good mood at this time.

He felt that Teacher Lan's words just now seemed to be a tacit consent for him to help these "students" answer questions for a fee.

While advertising for him, he said that his mathematics level is very high, and he also said that he hoped that everyone could take more care of him in life. How can he be taken care of in life? Of course, the only way is to redistribute wealth.

Teacher Lan is indeed a good person. He knew that his life was difficult and spared no effort to help him find money.

Qiao Yu realized that the teacher's wishes were realized. It is indeed not good to always catch one or two people raking in the wool. It is easy for them to spend all their living expenses. But if it is the entire Mathematical Olympiad class, everyone can pool money together to buy him a hand. The price can also be set a little higher. If so many people share it equally, everyone doesn't need to pay much, which is perfect.

Anyway, in Qiao Yu's opinion, this so-called Olympiad team is just a temporary grass-roots team.

For simple questions like that, I have to go to an Internet cafe to ask him to help me solve them, and my mathematical abilities are probably about the same.

When his classmates in Class 13 asked him for help, he still wanted to save face. The friendship between classmates was there and he was embarrassed to talk about the price, but he had no scruples when dealing with these unfamiliar people.

Along with the whispers in the classroom, another group of people came in soon. When everyone was seated, the class bell rang on time.

However, the discipline was probably not as good as usual. Many newcomers looked at the back row after being reminded by people around them.

Qiao Yu probably counted the numbers in his mind. There were more boys than girls in the Olympiad class. Not counting him, there were a total of eighteen people, fifteen boys and three girls. Unfortunately, none of the three girls seemed very good. Eye-catching.

From this point of view, it probably makes sense for Xia Keke to be named the star of the Rockets class.

"Okay, let's start class. Today we have a new classmate, Qiao Yu, who I have introduced just now. Let me tell you briefly about his future classmates. Although he is still a junior high school student, his math level is very high. I hope everyone can Learn more from him.

In the last class, we talked about the relationship between the roots and coefficients of polynomial equations. Today we mainly discuss several solutions to functional equations. The purpose is to explain the topic so that everyone can understand what to do when encountering functional equations. How to choose a treatment method.

First let’s look at this example question…”

For Lang Jie, today's class is also a brand new experience.

With Qiao Yu in the classroom, he put in a lot of effort to demonstrate his teaching standards.

There was no way, Qiao Yu sat down and listened to the lecture, which was both motivation and challenge for Lan Jie.

The main reason is that he really can't figure out Qiao Yu's true mathematical level now.

Listening to Qiao Yu's own explanation, he should have taught himself some mathematics content that only undergraduates would be exposed to, such as calculus and linear algebra. But if you are just an ordinary undergraduate and understand the mathematics competition questions of Little Libaba, you will definitely feel that Very difficult.

But during yesterday's phone call, this guy felt that the previous competition questions for Little Libaba were not difficult, and he had ideas for most of them.

He can only say that his strength is unknown when he encounters it in the real world, and he becomes stronger when he encounters someone strong.

So if Qiao Yu loses interest in mathematics because of his poor teaching, then his sin will be great.

Time passed quickly and three questions were answered. In fact, for most of the time, Lan Jie's eyes fell on Qiao Yu unconsciously.

Then I was somewhat disappointed.

After all, he is an experienced front-line teacher. He can still tell whether the students are listening carefully or pretending to listen carefully when in fact they are distracted.

Obviously Qiao Yu belongs to the latter.

Although this guy was empty-handed, didn't bring any other props, and wasn't lying there sleeping, his unfocused eyes couldn't deceive anyone.

But after thinking about it, he felt relieved.

One of the example questions I’m going to talk about today was one that Qiao Yu had already done in his office that day, and his answer was perfect. It’s really not interesting to continue listening to him explain it again, and it’s not going to attract his interest at all.

But if you talk about deeper content, others can’t keep up.

It's better to prepare training questions for this kid in the next Olympiad class, just in time to test the limits of this kid's ability. Unfortunately, there is no preparation today...

After finishing the two questions, Lan Jie simply clicked Qiao Yu's name.

"Qiao Yu."

"ah?"

"Well, let's explain the last example today to everyone."

Qiao Yu, who was thinking about what kind of flavor he should try for today after eating spicy noodles for two days in a row, raised his head and looked at the blackboard in front of him.

The blackboard has been wiped clean, and a question is hanging on the electronic screen next to it.

"Are you trying to advertise for me?" A thought came to Qiao Yu's mind. He glanced at the eyes that turned their heads and looked at him curiously, and walked towards the podium without any resistance.
