The students in the Department of Physics are not stupid, a small number of them can understand a little bit, and the rest can think about it for a while, and most of them can figure it out.

When the boy beside him was racking his brains and thinking about the problem but couldn't do it, Jiang Jianzhi unscrewed the cap of the pen and wrote a series of complex formulas in the opponent's notebook.

Reaching out and clicking on the notebook, Jiang Jianzhi looked up at the boy.

The boy who asked the question immediately remembered it. This is the knowledge he learned last semester. As long as he reversed it, he could solve the problem that troubled him.

Boy: "..."

At that moment, the boy's face turned red, and he felt that Professor Jiang didn't say anything, and his eyes seemed to say everything.

The last student also stepped down with a blushing face, and Jiang Jianzhi got up to wash his ink-stained hands.

As soon as the unsmiling Professor Jiang left, the large classroom where the needles could be heard came to life in an instant, discussing everything.

It has been almost two weeks since the art department moved to the Lanxi campus. The school forum post bar has been discussing this matter endlessly. Recently, the topic has always been unavoidable.

The place where the art department takes classes is not the same as the physics department, but this does not prevent everyone from talking enthusiastically:

"The dance majors are all good looking, each with a leg length of 1.8 meters. What did they eat to grow up?"

"I saw a young lady dancing folk dance this morning in the three cafeterias. She was amazing. She was white and beautiful, and her waist was thinner than my thighs."

"There are also some very good-looking people in the painting profession. If you compare them like this, we will not be able to play the grass in an instant."

"Where are you going? I told you that I went to the forum of the old campus to find out. There is a senior who just graduated..."

When Jiang Jianzhi came in through the back door, a classmate happened to flip through the photos saved from the forum to show the people around him, his voice was uncontrollable excitement and excitement:

"Look, look, does this senior Qi Bai look amazing? It's a pity that he graduated this year, otherwise we can meet him this time."

Qi Bai?

Hearing the familiar name, Jiang Jianzhi paused, standing behind the student and swiping at the other's phone, what caught his eye was a face with sharp eyebrows.

It was indeed Qi Bai.

But his hair was still black at the time.

The pixels of the photos are not high, and the facial features can be seen clearly, which looks like a long-distance candid shot.

Not knowing that the professor was standing behind them, someone took a closer look and said directly, "Isn't this my dream lover?"

"Don't think about it, this is gay, your gender can't be eaten by the lover of your dreams."

"Ah? Really fake?"

"Be true, everyone in the old school knows it."

A boy in the front row heard the discussion behind him and couldn't help but turn around and joke: "Huh? Then my chance is..."

The boy maintained the posture of turning around, but the words behind him stopped abruptly, like a goose strangled by his neck, his eyes widened and his face full of horror.

"How's it going?" Seeing that he froze, the person who spoke first thoughtfully helped him add:

"Senior Qi Bai is gay, is your chance here?"

Boy: "..."

"What the hell are you doing?"

Aware that his expression was wrong, the man followed his gaze and turned his head to look behind him, facing Professor Jiang's indifferent face.

"!"

The mobile phone in the man's hand fell on the table without a firm grip, and there was a loud 'click'.

Not caring about the phone, the man stood up and said, "Teach, professor..."

The classroom that noticed something was wrong was quiet again. Jiang Jianzhi looked away from his mobile phone and looked at his students with a light tone:

"I said at the beginning of the semester that I was not allowed to bring mobile phones in my class."

Today's students rely too much on electronic products. They don't listen carefully when they play with their mobile phones in class. They use their mobile phones to take pictures of the knowledge points that must be memorized.

Therefore, Jiang Jianzhi is not allowed to bring mobile phones in class, and requires students to take notes with their hands and minds.

He is strict. When a student is one or two points short of passing the final exam, he will not, like some teachers, try his best to give one or two points to let the students have a pleasant vacation.

Some old professors were afraid that Jiang Jianzhi's ruthlessness would cause dissatisfaction among students, and advised him not to be so serious.

Sometimes it is enough to open one eye and close one eye, so that the failure rate is low, and the teachers and students of the school are happy.

Jiang Jianzhi said with a stern face: "They are so embarrassed to be happy after the exam?"

Professor Jiang seeks truth from facts, and the old professor: "..."

Old Professor: Excuse me.

Jiang Jianzhi is only a few years older than these students, and he has also taught students older than himself, but no one dares to question him——

At least no one dared to take out his mobile phone in his class.

Not to mention playing games online.

At this time, Professor Jiang's expression was flat, and his tone of voice was exactly the same as usual, not even a questioning.

But the student whose gossip was caught was beating fast. She didn't expect Jiang Jianzhi to come in through the back door, and apologized nervously, saying that she would not bring her mobile phone to class next time.

Jiang Jianzhi didn't buy it: "Before the next class, review it in three thousand words."

The student bowed his head: "...Yes."

In the end, Jiang Jianzhi swept away the boy who said that Qi Bai was gay and that he had the chance to leave.

Isn't it just a hilarious sentence, I didn't bring a mobile phone illegally, why did Professor Jiang look at me like this?

On the podium, Jiang Jianzhi looked at the students below who lowered their heads to hold quails, and his voice was cold:

"The recess is for you to relax, revise and sort out the newly received knowledge, not for you to talk about others behind their backs."

"Next time a similar situation occurs, I can write a recommendation letter to the school and ask you to transfer to the journalism department next door."

This is the first time that Professor Jiang has punished someone to write a self-criticism since he taught them for so long, and anyone with a discerning eye knows that he is angry.

Everyone thought that Professor Jiang was displeased when the students brought their mobile phones into the classroom, but they didn't expect that his first sentence was to tell them not to talk about others.
