The weekend is over, and the storms of the previous two days have subsided.

At the school gate, there were crowds of people, shoulder to shoulder, and the students wore the uniforms of Jianghai No. 1 Middle School, which were all white and blue.

At the entrance of the school, a piece of granite marble more than two meters high is engraved with four big characters of Jianghai No. 1 Middle School.

The students who can be admitted to Jianghai No. 1 Middle School are all smarter, hard-working, and lucky.

Fang Ding is also in the flow of people.

Not outstanding.

It's just that I have a schoolbag on my back, and my whole temperament feels weird.

Stepping into the classroom with door number four, I sat down in the penultimate row by the window.

The penultimate row is the window seat, usually the protagonist's seat. Some people have analyzed that it is because of the good lighting, which can drag out the protagonist's delicate facial features and sharp edges and corners.

"Jingle Bell~"

A crisp class bell rang.

A tall female teacher in a black suit, holding a stack of textbooks and materials in her arms, walked calmly onto the podium.

He has fair skin, wears a pair of black gold-rimmed glasses, his eyes are embarrassed but not spiritual, and his long black and delicate hair is draped over his shoulders, which looks generous and decent, and has a unique style.

In Fang Ding's memory, this personal information soon surfaced-

Willow in the stream!

The math teacher of the fourth class is also their homeroom teacher.

He is in his thirties, but he is well maintained, and he is still in the state of twenty-five or sixteen.

However, this Teacher Liu was a violent temper and started a fire, and the whole class was silent, and no one dared to touch her brow.

But generally not the overall grades of the class declined, or major accidents such as student fights, Liu Zaixi's temper is still very good.

"Start class!"

There is not much nonsense, Mr. Liu has already written the blackboard and wrote down four big words: space vector!

An important part of high school math.

I have to say that Mr. Liu's explanation can be described as vivid, every word is exquisite, fascinating, and empowering.

In a short ten minutes, the students have a deep understanding of spatial vectors.

The whole classroom was silent, all thinking seriously.

Suddenly, a deep and long snoring broke the atmosphere.

"Fang Ding, wake up." A little fat man next to him hurriedly tugged at the corner of Fang Ding's clothes with his hand, but Fang Ding was too heavy to sleep, and he was unconscious.

The lecture came to an abrupt end.

On the podium, Liu Zaixi helped the frame of the mirror, his face became gloomy and terrifying, there seemed to be a fierce light flashing in his eyes, and the whole person was like a peerless fierce god, and everyone was frightened and lowered their heads, not daring to look directly.

The little fat man quickly retracted his hand, frightening and motionless, and the cold sweat behind his back wet his clothes.

"Fang - Ding ——!"

Teacher Liu was furious, like a lion roaring in Hedong, Fang Ding woke up from his sleep and was frightened.

"I'll go, I just heard the sound of a tiger roaring." Fang Ding touched the cold sweat and complained.

"Li Chenglong, why are you sweating so much behind your back? Is it so hot? Fang Ding looked at the little fat man who was sitting precariously, and said incomprehensibly, not noticing the earth-shattering murderous aura coming from the podium.

"Fang - Ding ——!"

"Huh? Arrive! Fang Ding stood up unconsciously. Suddenly, I saw the fierce Liu Zaixi on the podium.

Subconsciously hit another spirit.

But he couldn't help but complain in his heart: "The fear of the owner of the original body for Liu Zaixi is engraved into the depths of the soul!"

Even me, facing the fierce Liu Zaixi, I have a certain fear. ”

This is terrifying, isn't it!!

"Dare to sleep in my class, are you not small?"

Liu Zaixi's lenses reflected the fierce light in her eyes, and the murderous aura made the entire fourth class tremble.

Only then did Fang Ding react, it was really too monotonous the knowledge on the water blue star, he just skimmed through the content of the textbook roughly, and then integrated the space vector.

When people are bored, they are easily mentally tired.

So, drowsy, isn't it a matter of course?

"Mr. Liu, I didn't sleep!" Fang Ding began to make something out of nothing, and his tone gradually returned to normal, "Teacher Liu, I really didn't sleep, I was thinking about what you said just now. ”

"Humph! Full of nonsense, Fang Ding, when did you learn to be oily and slippery? Liu Zaixi snorted coldly, extremely angry.

"Teacher Liu, I'm really thinking about the problem, why don't I make it for you on the spot on the same day?" Fang Dingyi said in a righteous manner, looking extremely innocent.

Liu Zaixi lifted the frame of his glasses, and sneered at the corner of his mouth, this question, but the big question of the college entrance examination two years ago, you still made it on the spot, unless you are a genius.

"Good! If you can't do it, call me a parent! ”

Liu Zaixi said coldly, but he sneered in his heart, he will be hung on the blackboard later, you don't ask for mercy.

Fang Ding smiled faintly, walked calmly, and walked to the podium step by step.

Picking up the chalk, he suddenly thought of something, turned back to Liu Zaixi and said, "Teacher Liu, I want to make a bet with you, if I do this question, then you have to allow me not to listen to your class in the future." ”

"What?" Liu Zaixi has brought so many students, and there is still a person as strange as Fang Ding.

secretly said in his heart: "If you want to pretend to be thirteen and pretend to the end, then I'll see how you end up later." ”

He lifted the frame of his glasses again, and in the lenses, a touch of cunning flashed, and he also said: "I promise you!" However, if you can't do it, in the future, for all my math homework, you will have to pay twice as much as your normal classmates. Can you do it? ”

"Good!"

Fang Ding didn't think about it, and agreed.

Under the podium, Li Chenglong, who was sitting precariously, was stunned.

Did Fang Ding take the wrong medicine today, or was his brain kicked by a donkey?

Dare to speak like this, and he is not ashamed to solve the problem on the spot.

Just now, he listened carefully to the class, and Mr. Liu said that there were no more than ten of them in the college entrance examination that year.

Fang Ding estimated that he had overslept, and he would have good fruit to eat in the future.

Almost everyone had this idea, the same eyes, looking at the fool's eyes, staring directly at Fang Ding.

In the eyes of everyone, Fang Ding moved the chalk!

I saw that he glanced at the topic, took a random point, and established the coordinate system.

Then, one coordinate point after another was listed, very fast, and almost not calculated.

You know, taking coordinate points, in a space, there are many things used.

Trigonometric functions, the Pythagorean theorem, geometric calculations, the difficulty of this problem is to take the coordinates.

But in less than a minute, Fang Ding wrote densely, almost half of the blackboard.

Thirty seconds later, Fang Ding stopped his pen, patted the dust off his hands, and sat back in his original position.

There was an uproar down there.

"Well, this step is right here, isn't it?"

"How are the coordinates of point B calculated?"

"Can this coordinate still be taken like this?"

…………

On the podium, Liu Zaixi looked stunned.

The originally gloomy face has long been thrown out of the clouds.

Because of this problem, it took him more than five hours to solve it at the beginning. Moreover, the method is not as simple as Fang Ding's.

At this time, Fang Ding's voice sounded at the right time: "Teacher Liu, do you still count what you promised me?" ”
