I was the leader of the righteous path in high school.

Ms. Shen Yun, the math teacher of Class 35, is also the homeroom teacher of Class 14.

Although there are teachers on duty during evening self-study sessions, since it's the senior year, Mr. Shen usually stays in the teachers' office in the senior building, occasionally making "ghostly appearances" behind doors, outside windows, or in inconspicuous corners of classrooms.

The senior high school building has four floors, with classrooms and offices for each grade located on the respective grade's floor.

Apart from the Dean of Students having a separate office on the fourth floor, the entire grade only has that one office.

When Gu Yun walked in, the teachers' office was brightly lit.

Gu was not a regular here; he was an unremarkable student who never caused trouble.

His grades were abysmal in Class 35 of the senior year, so naturally he wouldn't take the initiative to ask questions or try to get attention from his teachers.

Shen Yun happened to be in the teachers' office, and Gu Yun, holding the test paper, went straight over.

"Teacher Shen, I have a question."

Shen Yun glanced up at him, and after seeing that it was Gu Yun, nodded slightly, indicating that Gu Yun should put the test paper on the desk.

Shen Yun and Zhang Qingshan are from the same cohort and are both in their forties, but they hold the title of senior teacher, belonging to the experienced teacher group.

If the old teacher's apparent inaction was out of necessity, then he has already achieved everything he could, making him a seasoned veteran teacher.

Despite having countless students, he was still very serious about them. Seeing that it was Gu Yun, who had recently "turned over a new leaf," he took a sip of tea and said, "What is it?"

He glanced at the exam paper; it was last year's college entrance exam in mathematics in Los Angeles.

The difficulty level is moderate in the college entrance examination; it's somewhat challenging, but still manageable.

First, look at the score.

121? !

Shen Yun immediately thought that Gu Yun was deceiving her, and couldn't believe it for a moment.

Normally, it's hard enough to pass an exam, and 60 or 70 is the norm. How could I possibly score 121 on a medium-difficulty college entrance exam?

It's important to know that this is definitely considered top-tier in the college entrance examination, completely different from the previous level of being half-baked and incompetent.

Shen Yun wanted to ask, but then thought of the other person's diligent attitude towards learning.

Ok……

Whether it's true or false, it's best to believe it first and not spoil the other person's enthusiasm for learning.

Shen Yun has been engaged in education for twenty years, and has seen countless students and encountered many oddballs.

He had seen true geniuses who could maintain excellent grades without much study.

Even if a student like Gu Yun, who is of average talent, suddenly has an epiphany and realizes the importance of studying hard, his potential will not be very high.

After all, a teacher who has taught a student for more than two years has a good idea of ​​whether the student is smart or not.

What's more, the other side is just giving up.

Even if I've been studying harder lately, my performance shouldn't have improved this much.

"What's wrong?"

"Look at this problem, teacher, it's an arithmetic sequence..."

A dozen minutes later, the bell rang for the next evening self-study session.

Shen Yun continued explaining the problem to Gu Yun for several more minutes before reluctantly ending the session, looking at Gu Yun with a surprised expression.

From the questions he asked himself, he could tell that Gu Yun understood the exam paper.

Sometimes my understanding is different from his, but after he points it out, I suddenly realize and deduce the correct answer.

He actually knows it?!

Shen Yun was momentarily at a loss for words. He instinctively picked up the teacup beside him, took a sip of strong tea, and said, "Gu Yun, your progress over the past two weeks has been remarkable!"

He was now certain that Gu Yun's math skills had improved significantly in just a few days.

Or perhaps they didn't take the initial placement test seriously, drifted through it aimlessly, and then prepared to make a name for themselves.

too frightening.

Shen Yun found it hard to believe that a student he considered to have average talent could have made such a great improvement in just two weeks!

To put it another way, it's like suddenly seeing your own pig turn into Zhu Bajie (Pigsy from Journey to the West).

Gu Yunke will not expose his system.

Or even if he did say it, others wouldn't believe him.

So he could only rub his nose, remembering the profound truths Shen Yun had spoken to the class before, and flattered her, "Teacher Shen, didn't you say that as long as you thoroughly understand the textbook, you can easily score over 120 in math?"

"These past few days, I've been studying all of my high school math..."

I read it through once and gained a lot.

"And I also did the '53' practice book, and finished all of it, which is why I made such progress."

"Teacher, you also said that a journey of a thousand miles begins with a single step, and a great river is formed from countless small streams. My hard work in studying is all thanks to your teachings."

"what……"

Shen Yun felt as if he had met his first love when he was young, and the other person had accepted his confession. He felt a surge of bittersweet joy and a sense of relief, and his face was full of wrinkles from smiling.

"Hey! I knew the teacher wouldn't lie to you, right? You've all been listening to me for a long time, and look, it's working!"

Gu Yun laughed and continued to flatter: "I didn't realize it before, but I've been studying hard recently and I now understand the value of your more than 20 years of teaching wisdom. It can save me from taking many detours."

"Hahaha! That's how it is, that's how it is."

Shen Yun laughed so loudly that it attracted the attention of the other teachers in the teachers' office, who couldn't help but pretend to be serious and coughed twice.

"Alright, go back to the classroom and study. If you don't understand anything in the future, feel free to ask."

Teachers all have a little dream in their hearts, especially veteran teachers.

They were all fond of teaching, enjoyed instructing gifted students, and relished the experience.

However, seeing that the mission was not yet completed, Gu Yun could not leave.

He suggested, "Teacher, there are some questions involving connections that I still don't understand. Could I ask them first?"

"For example, when you combine vectors and derivatives, don't you have to calculate the vector first and then calculate the derivative?"

It took Gu Yun a lot of time to find these kinds of questions because they were extremely rare; normal questions wouldn't even appear on them.

Fortunately, there were such test papers in the advanced class, and Gu Yun was able to find a few questions by borrowing Su Nianshan's test paper.

It must be said that it is indeed quite difficult.

Gu Yun sometimes wondered how Su Nianshan's brain worked, finding things difficult for him but easy for her.

Sure enough, a genius is a genius; you can't learn that.

Shen Yun frowned immediately upon seeing the question.

The reason is nothing other than...

This test paper was created by the grade's math team, and he was in charge of it.

How did the test papers for the experimental class end up in his hands?

Shen Yun suddenly remembered the gossip she had heard about eating here yesterday.

Oh, Su Nianshan is his sister.

Not surprising then.

He explained it to Gu Yun with a cheerful smile, and Gu Yun nodded in agreement.

The two men were teaching each other by example, appearing to be "brothers in harmony" and genuinely happy.

Their conversation was interrupted by a cough:

"Ahem!"
