Chapter 25 Good Teacher Ranjie
Without giving the new and old classmates much time to exchange pleasantries, Ranger just followed a few people into the classroom.

The moment he saw Qiao Yu, Lan Jie couldn't help but smile. He came to the classroom five minutes early today just to see if this kid was here. Now that he saw him, he felt relieved.

"Ahem, everyone isn't here yet, but let me introduce them to you all first. Today we have a new student in our Olympiad class, Qiao Yu. Although Qiao is from the junior high school department, his math level is very high. If you have any questions in the future, you can find an opportunity to ask him. Of course, he is younger than all of you, so I hope you can help Qiao Yu more in your life."

Although considering that saying this in class might undermine the confidence of many students in the Olympiad class, Ranger decided to give these high school kids a hint first.

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

The same is true for mathematics. After all, various training and exams are required in daily life.

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.

Rather than getting hit later, it is better to give these arrogant guys a clear message in advance.

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

Of course this is normal.

Sixteen or seventeen years old is the age when children are proud and arrogant. Those who are selected into the Olympiad class are the best in mathematics in the class. They can usually get full marks in exams. How can they accept that a junior high school student has a higher math level than them?
Fortunately, Qiao Yu had gotten used to being watched over the past two days, so even though all the attention was focused on him, he didn'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 tacitly approve him to help these "classmates" answer questions for a fee.

On the one hand, they advertised him, saying that he was very good at mathematics, and also said that they hoped that everyone would take care of him in life. How could they take care of him in life? Of course, the only way is to redistribute wealth.

Teacher Lan is indeed a good person. Knowing that he had a difficult life, she spared no effort to help him find money.

Qiao Yu felt that the teacher's intention was appreciated. It was not good to always take advantage of one or two people, as it would easily make them spend all their living expenses. But if it was the entire Olympiad class, everyone could pool their money together to buy him out, and his price could be set a little higher. If so many people shared it equally, each person would not have to pay much, which was perfect.

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

He has to go to the Internet cafe to ask him to help solve such simple problems. His math ability is probably just that level.

When his deskmate from Class 13 asked him for help, he still had to have some dignity. Their friendship was there, so he was too embarrassed to talk about the price. But when facing these people he was not very familiar with, he had no scruples.

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

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

Qiao Yu probably counted in his mind and found that there were more boys than girls in the Olympiad class. If he wasn't counted, there were a total of 18 people, 15 boys and 3 girls. Unfortunately, the three girls didn't seem very pleasing to the eye.

From this point of view, it probably makes sense that Xia Keke was named the class beauty of the Rocket Class.

"Okay, let's start the class. Today we have a new student, Qiao Yu, who I have just introduced. Let me briefly tell you that 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 will mainly discuss several solutions to functional equations. The purpose is to hope that through the explanation of the questions, everyone can understand how to choose the method to deal with when encountering functional equations.

First, let’s look at this example…”

For Lang Jie, today's class was also a brand new experience. With Qiao Yu in the classroom, he tried his best to show his teaching level.

There was no way out. Qiao Yu sitting down and listening to the class was both a motivation and a challenge for Ranger.

The main reason is that he really doesn't have a clear idea of ​​Qiao Yu's true mathematical level.

From Qiao Yu's own description, he probably taught himself some of the math content that undergraduates would only be exposed to, such as calculus and linear algebra. But if one only has an average undergraduate level and understands Xiaolibaba's math competition questions, one would definitely find them very difficult.

But during the phone call yesterday, the kid felt that Xiaolibaba’s previous competition questions were not difficult, and he had ideas for most of them.

All he could say was that his strength in the real world was unknown, and he would become stronger when facing a stronger opponent.

So if he didn't explain it well and made Qiao Yu lose interest in mathematics, then he would be committing a great sin.

Time passed quickly. After explaining three questions, most of the time, Langjie's eyes unconsciously fell on Qiao Yu.

And then I was somewhat disappointed.

After all, he is an experienced front-line teacher. He can still tell whether students are listening attentively or pretending to listen attentively but are actually daydreaming.

It is obvious that Qiao Yu belongs to the latter.

Although this guy had nothing in his hands, 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.

Qiao Yu had already done one of the examples in today's lesson in his office that day, and he answered it perfectly. It was really meaningless to continue listening to him explain it again, and it was completely impossible to attract his interest.

But if you talk about deeper content, others won’t be able to keep up.

Why not prepare training questions for this kid in the next Olympiad class? It will be a good opportunity to test the limits of his abilities. Unfortunately, I didn't prepare any today...

After finishing the two questions, Langjie simply called out Qiao Yu's name.

"Qiao Yu."

"what?"

"Well, you can explain the last example question today to everyone."

Qiao Yu, who was thinking about what flavor to try today after eating spicy strips for two consecutive days, raised his head and looked at the blackboard in front of him.

The blackboard had been wiped clean, and a question was displayed on the electronic screen next to it.

"Are you thinking of advertising for me?" This thought popped up in 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.

As he walked a few steps toward the podium, Qiao Yu was still sighing in his heart that Teacher Lan was so honest that he felt a little embarrassed.
