Just turned over a new leaf and became a wise and intelligent student

Chapter 66 I kept the teacher out of class
"Hello? Teacher Ji? Oh, yes, it's me, Zhang Jingxian from the senior year. I want to trouble you for something."

"Yeah, okay, then I'll ask him to come find you now."

Zhang Jingxian was gentle and kind when she was on the phone, and she didn't have the energy to scold people at all like she did in the classroom.

Xu Qingshan just stood there and laughed.

He didn't want to go and act out some awkward, second-year drama of "contempt - self-proof - slap in the face" with a strange teacher.

This beauty trap is so effective, it can be solved with just one phone call.

"Okay, go to Houde Building, Grade 1, Class , and find Teacher Ji. I'll get Teacher Lou's Physics Competition books for you during evening study. You can study these, but your grades in other subjects must not drop."

Zhang Jingxian's beautiful eyes were rolling, pretending to be angry, but she was actually full of charm.

"Thank you Miss Zhang, it turns out that a beautiful lady's face is very useful."

Xu Qingshan pretended to be serious and teased Zhang Jingxian, but he walked away quickly, avoiding the teacher's light hit, and went towards the direction of the first grade Houde Building.

"Smelly boy"

Zhang Jingxian's cheeks were flushed.

She opened the lesson plan and continued to prepare the review plan for next week.

Xu Qingshan walked through the corridor towards Houde Building. When he passed Class 1, he caught a glimpse of Jiang Huanxi, who was curled up in her seat and poking at something with an eraser, and was stunned for a moment.

What is this silly girl doing?

Jiang Huanxi was sitting there concentrating on poking the eraser with a mechanical pencil that had no refill, and he was becoming autistic as he did so.

What a big deal!

Not only did she fail to redeem herself in this biweekly exam, she even ranked below Xu Qingshan in the grade!
She only scored 657, not even in the top ten in the class!
Ranked exactly 25th in the grade!
Damn Xu Qingshan.

But it seemed like it had nothing to do with him, it was just his own confused mind.

Jiang Huanxi was very conflicted. In her clever little head, she was wondering if Xu Qingshan was using this dirty competition method to surpass her.

But after carefully reviewing it, I feel that it is more because I think too much.

Her kindness made her feel that condemning Xu Qingshan was unfair to him.

Xu Qingshan originally wanted to say hello to Jiang Huanxi, but seeing her strange and conflicted expression, he thought it was inconvenient and just continued walking forward.

Not long after.

He found Class 1 of Grade 2 at the end of the north corridor on the second floor of Houde Building. He went up the stairs and passed Class 1 to reach Class .

Tong Tong is in Class 1.

He walked calmly and confidently past the windows of Class 1 and Class 2 of Grade , like a male god who had accidentally entered the viewfinder of the window frame.

Xu Qingshan walked as fast as a dragon and had a nimble figure. His tall figure and elegant and handsome face were like a bullet that hit the hearts of his freshman classmates directly.

When a person's appearance and temperament are handsome to a certain extent, he can be attractive to both men and women.

The first year of high school also has self-study classes at this time, but they have to leave school early.

Everyone was packing up to leave, but when they saw the visitor outside the window, they stopped what they were doing.

There was an oval-faced girl in Class 1 who was staring out the window in a daze. When she saw Xu Qingshan, her brain froze for a moment, then she immediately reacted and hurriedly pushed her deskmate next to her.

"Tong Tong, Tong Tong! Your brother, your brother is here."

The girl's voice revealed excitement, and if you didn't know her, you would think she was a celebrity visiting.

"my brother?"

Tong Tong was concentrating on doing his homework. He was a little dazed when his deskmate pushed him like that. He just looked up and saw a familiar figure standing at the front door of the classroom.

"Hello, Teacher Ji. I am the student who asked Teacher Zhang to ask for your help. Can I come in?"

Xu Qingshan spoke in a low voice and with a respectful attitude.

"come on."

Teacher Ji, who was sitting behind the podium and wearing a pair of black-framed glasses, was about thirty years old. There were some papers and a few books piled on the podium desk. It seemed that he was correcting students' homework.

Xu Qingshan walked to the podium. He saw Tong Tong sitting in the middle of the class. He smiled at her restrainedly, then half-knelt beside the podium to communicate with Teacher Ji.

"Hello, teacher. My name is Xu Qingshan."

"Teacher Zhang said you want to learn the basics of the Mathematical Olympiad on your own?"

"Yeah, I want to improve my thinking."

Xu Qingshan quietly explained his thoughts to Teacher Ji.

"Okay, your idea is good, but don't be too stubborn." Teacher Ji pushed his glasses and took several books and a stack of printed exercise books prepared for Xu Qingshan on the table and put them in front of Xu Qingshan.

He thought about it and took out another piece of paper from the book.

There was only one question on a large piece of paper, and the question was not long.

"However, I just called your teacher Duan, and he said that you have great potential in reasoning logic and organizing your thoughts. Here is a question. Take a look at it. I will now explain to you the relevant knowledge points of the question. They are also marked for you in the Olympiad textbook. If you can solve it within three days, you will not be charged for these materials."

Teacher Ji had a smile on his face.

“Does this material cost money?”

Xu Qingshan curled his lips. He thought he could get it for free, but it seems that the beauty trap was not strong enough.

"Nonsense, these are all the inventory of the Digital Competition Team, and the school finance department needs to reconcile the accounts."

Teacher Ji pointed at the question with his finger.

"Stop talking nonsense and try it first."

Teacher Ji glanced at the time and saw that there were still ten minutes before school was over, so it would be okay for her to explain the question to this handsome young man who had a good impression of her.

"Ok."

The freshman students in the audience heard the conversation between the two and looked at Teacher Ji and the handsome senior on the stage with curiosity.

Teacher Ji began to briefly explain the necessary knowledge points to Xu Qingshan based on the questions on the test paper.

The paper is very blank, with only two lines for the question.

1.求最大实数M，使得对任何n都存在正数数列（ai）i=1的n方，（bi）i=1的n方使得2bi≥b i-1 +b i+1，2≤i≤n-1；ai平方≤1+i∑j=1 ajbj，1≤i≤n；并且an=M。

Xu Qingshan watched it very seriously.

He didn't know that this was a question that Teacher Ji had picked out from the national mathematics team selection exam held earlier this year.

Just now, when Teacher Ji was briefly explaining the knowledge points, he was listening very attentively.

to be frank.

When Xu Qingshan was doing the math questions for the college entrance examination before, he didn't have this feeling. There were only various routines and different ways of asking questions to cause trouble for the test takers.

He felt that this brief, yet-to-be-ended contact seemed to have given him a glimpse into the charm of mathematics.

"Okay, that's all. You can read it now and ask me if you don't understand anything. I'll go eat when the bell rings because I have to teach an evening class."

Teacher Ji’s attitude is already very good.

But this was also because he heard about the handsome young man in front of him from Zhang Jingxian and Duan Yongming, and he suddenly came to his senses and sprinted to more than 200 points in more than a month.

What teacher wouldn’t like such a potential student?

It’s just that Teacher Ji is the instructor of the Longjiang Experimental Mathematical Competition Team. From the perspective of the mathematical competition, he thinks that it is very strong for a student like Xu Qingshan who has no foundation to figure out this selection question in three days.

"Okay, teacher."

Xu Qingshan had already picked up a pen and listed the relevant knowledge points that Teacher Ji had just explained to him, while looking at the questions and the knowledge points.

I only watched it for a little over a minute.

Xu Qingshan's pen, which had just stopped, started moving again.

Teacher Ji looked at the tip of the pen curiously. He wanted to see what Xu Qingshan could write right now.

Is he fooling himself? Or does he have some ideas?

It’s better not to watch.

At first glance, he couldn't get out.

"Dingle bell bell bell bell"

The bell in Class 1, Grade rang.

But Xu Qingshan's pen was still moving, and Teacher Ji's eyes were still watching. The two men were extremely focused. The classmates in the class looked at the combination painting on the stage, thought for a moment, and then quietly ran out of the classroom.

Tong Tong originally wanted to wait for Xu Qingshan to say a few words.

But after observing Xu Qingshan and Teacher Ji for a while, she felt that they were not the kind of people who could be interrupted, so she gave up the idea.

The sky outside the window changed from bright to dark, but the lights in the classroom remained on.

Some students returned to the classroom after lunch, and Xu Qingshan and Teacher Ji were still there, one writing and the other reading.

What others fear most is the teacher staying after class.

Xu Qingshan was so good that he kept the teacher out of class and kept him under control for an hour!
