After the Villain is Reborn, I Hold My Golden Thigh

Outside the classroom, Lan Yin originally planned to chat with the teacher, whom Principal Chen called a professor, in the corridor at the entrance of the classroom.

However, her plan changed after Principal Chen proposed to go to the principal's office.

The classrooms of Class 11 of the third grade are on the second floor, and the principal's office is in a separate teacher's office building behind the teaching building.

It takes three minutes to walk from here to the principal's office.

Again and again, the class time is over halfway through.

But it doesn't matter, she said that we only talked for ten minutes.

Except for the time wasted on the road, Lan Yin felt that she should be able to answer the questions the other party wanted to ask in a few words.

…

A few minutes later, in the principal's office.

Beside the guest sofa by the window, Lan Yin was not polite and chose a single sofa closer to the door to sit down.

One step away from her, Principal Chen and Professor Mullin sat side by side on the couch and began their short chat.

Principal Chen picked up a test paper he had taken out from the desk drawer half a minute ago.

Professor Mullin, who was beside him, took the test paper and carefully held it in his hand.

"Student Lan Yin, this paper is yours, right? Can you tell me the solution to the last question of the test paper in detail?"

Professor Mullin spoke with sincerity and a hint of asking for advice.

Although he is a professor of mathematics at the university, in front of Lan Yin, he did not pinpoint his identity.

In his mind, academic level is the standard to measure a person's status.

At this time, Professor Mullin has been studying this question for three days!

After three days, he, a math professor, couldn't understand the girl's unique problem-solving method, so he came to Ningcheng No. 1 Middle School to find the person who solved the problem.

Lan Yin raised her eyes and glanced at the problem-solving steps on the exam paper in Professor Mu's hand.

In the next second, she finally knew the reason why the math professor in front of her asked her to chat alone!

——When she was taking the monthly exam, she was not paying attention, and the method she used to solve math problems was beyond the syllabus!

As for the problem-solving formula beyond the outline, in fact, in the near future, even in ten years, someone will discover this new mathematical idea.

But now, her problem-solving method is unprecedented.

Lan Yin lowered her eyes, she thought for a moment, considering whether to disclose this problem-solving method in advance?

Now that something has been revealed in her test paper, instead of letting this question make a lot of noise in the entire mathematics community, it is better to be generous and improve the mathematics level of the entire country.

What's more, this kind of problem-solving method is still the most elementary thing for her.

It's also because it's too elementary, so she used it habitually during exams...

After a while, Lan Yin, who had a clear decision, looked up at Professor Mu.

"Do you have a pen?"

She spoke in a light tone. The slightly soft and clear voice in the original vocal cords seemed to be a booster in Professor Mullin's heart at this moment! ——

"Yes, yes, yes!" Professor Mullin was a little excited.

He said, and took out a delicate-shaped pen from the inner pocket of the suit jacket he was wearing.

Then, his subconscious reaction was to respectfully hand the pen to the girl with both hands——

"Student Lan Yin, you use this." Professor Mullin's tone was respectful.

The best comes first, if the girl can teach him something, then she is his teacher.

Regardless of age.
