My Girlfriend Who Develops Through Development

After saying that, he glanced at An Youyu at the back of the classroom.

Lin Mo, who was watching the show, smirked, "This old man is obviously up to something!"

Hearing this, An Youyu remained expressionless.

Under everyone's gaze, she stood up, walked down the corridor to the podium, and nodded politely to Qi Bei.

Before Qi Bei could say anything, she picked up a piece of chalk from the podium and quickly drew a miniature mathematical model on the blackboard to the side.

After listing them, the calculations begin.

When she had calculated about one-third of the way through, she suddenly stopped, pointed to the latest calculation step, and said in a clear voice, "Classmates, please look, this mathematical model has now calculated about one-third of the way through. What would happen if we used formula number one at this point?"

As soon as she finished speaking, many students took out paper and pens and quickly began to calculate.

Qi Bei, Ye Hongjun, and the other two looked at the calculation breakpoints on the blackboard, quickly substituted the first formula into their minds, and after a simple mental calculation, the eyes of the four of them widened.

Wonderful!

That's great!

About seven or eight minutes later, a gasp suddenly rang out in the classroom.

"Fuck——"

A boy stood up in shock, holding up his scratch paper, and exclaimed, "Substituting into formula number one, we can directly calculate the final result! This is simply amazing!"

The students who hadn't actually done the calculations all looked incredulous after hearing what the boy said.

What kind of international joke are you kidding?

An Youyu's miniature mathematical model on the blackboard had only calculated about one-third of the results. By substituting it into formula number one, the remaining two-thirds of the calculation process could be omitted to obtain the result.

so funny!

But soon someone else stood up to prove it, "It really can calculate the result, wow! It's like magic, amazing!"

A girl who had also calculated the result looked at An Youyu on the stage and couldn't help but swallow hard. "An Youyu, how do you know so much about Formula One?"

"Teacher Qi didn't even mention this usage yesterday... I bet he didn't know it either, how do you know?"

Upon hearing this, Qi Bei's face flushed red, and he glared at the female student who had spoken, "What do you mean, 'Even I don't know?' How do you know I don't know?"

The female student gave an awkward smile. "Since Teacher Qi knew that, why didn't you tell us yesterday that Formula One could be used like that?"

"This one……"

Qi Bei coughed lightly, "Yesterday I just couldn't think of this solution yet."

"Shh..."

A chorus of boos erupted.

Qi Bei glared at him and said, "Anyone who boos again, get out."

"..."

Many students secretly grimaced, but dared not say anything.

Just then, a laugh came from the back of the classroom; the laugh naturally came from Lin Mo.

Qi Bei's gaze immediately locked onto Lin Mo, and he asked irritably, "What are you laughing at, kid? Did you eat farts?"

Lin Mo stopped laughing. "Professor Qi, could you please be mindful of your image?"

“It’s fine to talk like that in private, but this is a class. As a teacher, you should be mindful of your words and actions. Look at what you just said. As a teacher, do you think that’s appropriate? Do you behave like this when you’re teaching at Tsinghua University?”

The math students were secretly astonished to see Lin Mo actually retort.

Although they only attended one of Qi Bei's classes yesterday, Qi Bei managed to teach them the meaning of strict discipline in just that short class.

Even Ye Hongjun showed surprise in his eyes after hearing Lin Mo's words.

If it were him, he wouldn't dare say such a thing.

Qi Bei's lips twitched. "You're not a math major. I'm already being lenient by letting you audit the class. Don't be ungrateful. If you disrupt the class again, don't blame me for kicking you out."

After saying that, he turned to the female student who had spoken earlier and said, "Didn't you ask An Youyu a question? Hurry up and ask it."

The girl opened her mouth, "Teacher Qi, I just... asked."

Lin Mo's smile widened, but this time he didn't make a sound.

This old man...

That's funny!

Qi Bei frowned. "You already asked? I didn't hear you. Ask again."

An Youyu blinked. "I heard you."

Qi Bei: "..."

An Youyu looked at the girl who asked the question and explained, "I created this formula. During the National Mathematics Competition, I encountered a relatively simple problem that required a lot of calculations, so I wanted to take a shortcut and created this formula."

"Oh right, not only Formula One, but all twelve formulas on the screen were created by me. Compared to everyone else, I do know more about these formulas."

After saying this, she looked around timidly and asked hesitantly, "Does anyone have any questions?"

quiet!

At that moment, the entire math classroom was completely silent.

The silence lasted for four or five seconds before being broken by a gasp.

"She...she created them? All twelve formulas were created by her?"

Upon hearing this, the atmosphere in the math classroom instantly became as turbulent as boiling water.

"No wonder, no wonder!"

"My God! She can even create mathematical formulas? Is this the terror of a perfect scorer?"

"This... why does it give me the feeling of being a frog in a well, with a limited perspective?"

"Create a formula? One or twelve? My high school teachers never taught these things!"

"Dude, do you think a high school teacher could do that on their own?"

……

"Quiet!"

The moment Qi Bei's voice rang out, the classroom fell silent.

Qi Bei glanced at Li Jinzhao, who was standing there in a daze, and said, "These formulas all come from An Youyu's exam paper in the National Mathematics Competition Finals. She has more authority to speak on these formulas than anyone else."

"If she doesn't agree with your categorization, then you're wrong. If everyone categorizes things the same way, then everyone is wrong."

"Li Jinzhao, is there anything else you'd like to say?"

Li Jinzhao, who was suddenly called out, tensed up and shook his head like a rattle drum. "N-nothing to say."

"Sit down."

Qi Bei turned to An Youyu and nodded, "Girl, now that you're on stage, go ahead and explain the remaining eleven formulas in one go."

"it is good."

An Youyu naturally wouldn't refuse Qi Bei's request. After this brief respite, she was much calmer than before.

For the next twenty minutes or so, only An Youyu's voice could be heard in the large math classroom.

Formulas that are incredibly obscure to math students become remarkably simple under An Youyu's explanation.

Her explanations were quite direct and highly efficient, making them easy to understand. In particular, the imaginative and unconventional ideas she displayed during her explanations were captivating.

An Youyu, her mouth dry, stopped explaining. "Okay, that's about it."

Turning around, she habitually looked towards the back of the classroom and saw Lin Mo leaving through the back door. A hint of doubt flashed in her eyes.

why did you leave?

The moment that thought crossed her mind, her heart skipped a beat.

That bastard...

Could he really have gone to chat up the female senior?

"Clap clap..."

Qi Bei clapped his hands and came up to An Youyu, "Brilliant, a truly brilliant presentation."

The three mathematics academicians on the bench on one side also spontaneously applauded.

Absolutely brilliant!

As they clapped, a look of amazement flashed across the eyes of the three of them.

How could an eighteen-year-old girl have such a high level of mathematical ability?

They wouldn't have believed it if they hadn't seen it with their own eyes!

Is this the legendary genius?

Seeing that Qi Bei and the three academicians of mathematics had applauded, the students below the stage, who had come to their senses, followed suit and applauded as well.

At this moment, the way they looked at An Youyu was noticeably different from how they had looked at her at the beginning.

At first, they were simply amazed by An Youyu's stunning beauty and temperament, but now they are impressed by her mathematical abilities.

Why do they have to amaze them with their talent when they could make a living based on their looks?

Everyone here is a freshman from the senior year of high school, so why is An Youyu so outstanding?

really……

Without comparison, there is no harm!

Qi Bei noticed An Youyu's pursed lips and then waved to Ye Hongjun.

Ye Hongjun quickly got up and went to Qi Bei, whispering, "T-Teacher, what's the matter?"

Upon hearing the title 'teacher,' Qi Bei raised an eyebrow and responded in a low voice, 'Who told you to call me teacher?'

Ye Hongjun gave a guilty smile, "Teacher, I was indeed wrong about what happened back then, but so many years have passed..."

Before he could finish speaking, Qi Bei interrupted, "Do you think it's appropriate to talk about such old, trivial matters in class?"
