Chapter 13

Xu Jing came to the classroom and swept the students below for the first time.

Until he saw Jiang Fuyue, he took back his eyes with satisfaction.

"Before the formal class, I'll introduce a new classmate to you. Jiang Fuyue, come up -"

Jiang Fuyue got up and went to the podium.

The girl is tall and has long legs. She arrived in a few steps. One stop must be graceful.

Xu Jing stepped back and let the platform out: "introduce yourself."

The girl's slightly cold eyes crossed the crowd and her tone was flat: "Jiang Fuyue, class 3, grade 2, senior high school."

Then

No, then.

"Cough!" Xu Jing cleared his throat, "go down, let's start class..."

One is understatement, the other is calm, but I don't know that some people under the stage have exploded!

"Shit! Shit! Jiang Fuyue joined our class? What the hell? How did she buy Lao Xu?" Sun Cheng asked.

Lingxuan also had doubts in his eyes, but he was calm: "listen to the class first."

"... oh."

There are 26 students in the Mathematical Olympiad class, half of them are senior one and half are senior two, and the vast majority of senior two students like Ling Xuan have been learning from senior one.

After all, good seedlings are focused on as soon as they enter school.

Jiang Fuyue, who is a monk on the way and ranks the last in the grade, hasn't really started the class so far.

Sun Cheng rubbed his chin and thought, "Lao Xu's operation is coquettish enough..."

Lingxuan frowned: "if you want to talk about it, don't read it beside me."

Sun Cheng's lips are turned away. Who is he doing this for?

The weekly training is conducted in the form of special topic explanation. I talked about inequality last time. It's not over yet. Continue this time.

Soon, a class passed.

Jiang Fuyue had to admit that Xu Jing did have two brushes. Not only the professional knowledge is excellent, but also the ability to guide students to think is perfect.

For example, an inequality proof problem can be divergent and extended to the Chebyshev constant problem of the unit circle, and then the square Chebyshev problem and the real interval standard Chebyshev problem can be derived.

"... OK, let's have a rest and talk about the papers next class."

As soon as he left, the quiet classroom became lively.

Jiang Fuyue turned her pen with one hand and looked at the blackboard carelessly. In fact, she was retesting Xu Jing's steps and thinking about another simpler solution.

"Do you understand?" suddenly, a slightly sarcastic voice sounded.

Jiang Fuyue turns her eyes, doesn't know, and moves away.

Sun Cheng: "

"Hey! What are you doing here?" he insisted.

Jiang Fuyue was too lazy to answer.

"I don't know. Is it to chase ah Xuan? Look at you. You're not ugly. Why do you think so?"

"Ah Xuan's vision is so high that he certainly doesn't like you. As the saying goes, there is no grass in the world. Bye, bye, next better..."

"Hello, noisy." Jiang Fuyue looked at him coldly.

With his eyes facing each other, sun Cheng was overwhelmed, and then

He blushed hopelessly.

Lingxuan didn't go to the toilet. When he came back, he saw his good brother sitting in his seat, looking dull and absent-minded.

"Sun Cheng?" he patted him on the shoulder.

"... ah?"

"What's the matter with you? Your soul is gone." he teased casually.

Unexpectedly, sun Cheng was like a cat with its tail stepped on. He was nervous for a moment: "is it so obvious?"

Ling Xuan: "

I don't know what he's doing again. Ling Xuan simply ignored it. The test paper turned over and his eyes fell on the proof question. He always felt something wrong

Sun Cheng's two fools were still whispering: "I seem to know why Lao Xu..."

As soon as the bell rang, Xu Jing appeared on time.

After opening the multimedia, I directly projected the answers on the screen, "... This set of questions is difficult. After all, it is the League prediction volume in the district. But it is not so difficult. I think many people in our class have finished it all, of course, right or wrong. Let's look at the first question first..."

Xu Jing's state at this time is completely different from that in class. It's like a tiger who has found superior prey. He is bound to take the most vigorous posture and show the sharpest claws and teeth to complete a incisive hunting.

Regular League papers have no multiple-choice questions, only fill in the blanks and answer them. The number is small, but the score is heavy.

The first eight fill in the blanks, eight points for each question, add up to 64 points.

The scores of the last three solutions are 15, 15 and 26 respectively, with a full score of just 120.

In the solution, another inequality was proved to account for 26 points, which was also the one that made Xu Jing inevitably go into a misunderstanding.

Therefore, he set aside enough time, "if you can understand this problem thoroughly today, you will have mastered half of it. Did anyone do it?"

While Xu Jing spoke, he raised his eyes and swept them. He didn't know whether he was intentional or unintentional. He walked back and forth on Jiang Fuyue several times.

The latter didn't even give him a look, lowered his head and didn't know what he was writing.

Xu Jing had a snack plug and took a deep breath: "then I'll call the roll. Ling Xuan, sun Cheng and Jiang Fuyue, you three can write on the blackboard and others can discuss freely."

Ling Xuan and sun Cheng were obviously not drawn for the first time. They looked calm when they went up.

In any case, such a problem will not lose face if you make a mistake.

Jiang Fuyue, on the first day of her life, unexpectedly won the prize and looked calm.

Tut

Sun Cheng glanced at her, and the scene of meeting her eyes again came to his mind. His heart beat faster unconsciously.

damn!

With a low curse, he quickly moved away and dared not look again.

Jiang Fuyue knew nothing about it. Even if she knew, she probably wouldn't have any reaction.

The three turned their backs and began to write on the blackboard silently.

Jiang Fuyue finished writing first, put down the chalk, and sat back in place without waiting for Xu Jing to speak.

I feel heartbroken.

Sun Cheng followed closely, but not because he had finished writing, but because he could only prove this step. Although he read Ling Xuan's answer in advance, he still retained his original idea.

"Miss Xu?"

"Well, go down."

After another seven or eight minutes, Ling Xuan ended. At this time, he occupied half of the blackboard. The dense steps and numbers jumped on it. At first glance, it was quite spectacular.

Comparing the answers of Jiang Fuyue and sun Cheng, they are too simple to be seen.

Lingxuan: "I'm ready."

Xu Jing took back his eyes and nodded at him, "go back to your seat." then he asked everyone, "do you understand what they wrote?"

Some people nod, others shake their heads.

Xu Jing said again, "one of them did it right. If you think sun Cheng did it right, raise your hand and let me see?"

Sparse three or two.

"If you think Ling Xuan is right, raise your hand."

Brush——

A large area.

"Think Jiang Fuyue did the right thing?"

The audience was suddenly silent. In such silence, Jiang Fuyue raised her hand.

She didn't look around. She was silent all the way.

When Xu Jing asked, she answered. It seemed that she was only completing a simple question. As for whether it was related to herself, it didn't matter.

Just then, the other hand in front of me hesitated and slowly raised
