My Identity As A Schoolmaster Has Been Exposed

Xu Cong's eyes twitched. He suddenly felt that he didn't understand Lin Mengjiao. This feeling was obviously...

hiss!!!

indescribable!

Lin Mengjiao's ability unexpectedly leaned up, but now she has leaned up, and she has no intention of pushing away.

Instead of pushing away this time, she raised her jade lotus-like arm and embraced Xu Cong.

"hiss…"

Xu Cong took a deep breath and slowly raised his hand to hug the girl tightly. Lin Mengjiao's skeleton is not big, but it has meat, but it is not fat!

The body proportions are perfect, and the waist is extremely slim!

Bee waist!

Probably that's it, the night is quiet!

Two people's heartbeat is fast!

Faster than usual.

"Boom boom boom! boom boom boom! boom boom boom..." boom boom! boom boom boom! boom boom boom..."

It took a long time for Lin Mengjiao to leave Xu Cong's arms and hurriedly said to him: "It's too late, the dormitory is about to close!"

The moment Lin Mengjiao wanted to leave, Xu Cong took her hand, and in the darkness, the two figures overlapped.

After a long time, Lin Mengjiao hurried away!

There are similar words in my mind: "Xu Cong, you big bad guy! Big bad guy! Big durian mang! My first kiss! Humph! Damn it, it's that kind of kind!!!"

Xu Cong pursed his mouth and smirked.

Just touch it? Is that also called it? It must be French!

Back to the dormitory, Xu Cong reflected, is this caused by the atmosphere, or is it caused by hormones in the body?

He looked at the ceiling, feeling happy, and the roommates looked left and right.

"Xu Cong is a nympho?"

"Are you in love?"

Just when they were about to ask Xu Cong, someone came.

"Boom boom boom!" A knock on the door sounded.

"Is this the dormitory of Xu Cong? Hello everyone, I brought ice cream! Can I meet Xu Cong?"

Xu Cong got up to open the door, and asked a little surprised: "Are you...?"

The other person is slender, wearing glasses, very humble and shy, "I have something to ask you, let's eat ice cream first!"

This person will come, and Xu Cong doesn't hate it.

The roommates ate his ice cream, and they were naturally polite.

"I'm in the third year of high school, I'm Liu Yixiang..." Before he could finish his words, several good buddies immediately screamed.

"Liu Yixiang? High school senior! Are you kidding? You came to our dormitory to find Xu Cong in the middle of the night and ask questions?"

Liu Yixiang is a well-known student in the school. In the previous monthly exam, he even scored second place with 20 points!

The roommates were dumbfounded and asked straightforwardly: "Senior, do you want to ask the sophomore?"

In the hearts of the roommates, Xu Cong is the N01 in the second year of high school, and he should not be able to do what he wants in the third year of high school.

Liu Yixiang looked at the crowd and asked in a little surprise: "Why, don't you know Xu Cong, you will be in the third year of high school?"

"He did an extra high school biology test paper for the mid-term exam!"

The roommates have protruding eyes and their mouths are so wide that their jaws can fall to the ground.

"What! What? What did you say?"

"My ears don't work well, can you say it again?!"

Liu Yixiang continued: "Student Xu Cong, it took more than an hour to do two exam papers, senior high school biology and senior high school biology, and then hand in the paper ahead of schedule."

Damn it!

Fuck!! Fuck!!!

The roommates are all in the head."

If their brains can open the barrage, then the whole screen will be fucking fucking..."

It's all covered by these two words, besides that, all the things in my mind can't be seen and bought.

They almost didn't retract their chins, looked at Xu Cong, and asked dumbfounded: "Really, really?!!"

Xu Cong waved his hand and said lightly: "It's all over!"

Everyone, "!!!"

Suddenly, a classmate suddenly screamed, "I remember the head teacher seemed to mention it! What did Xu Cong say shouldn't be the perfect score in nine subjects! It seems to be ten subjects!"

"Could it be this!"

"Xu Cong, you got a perfect score when you did the biology test for the third year of high school?!!!"

Other students were puzzled, "Is there anything about this?"

"I remember!"

"I seem to remember too!"

"Fuck!!!"

"Xu Cong! You are too deep too! Too strong!"

"God! I will call you Xu Shen from now on!"

Liu Yixiang looked at the crowd and took a cold breath, "Xu Cong, are you too low-key!"

"It's me instead, I think I will show it up and let them face it."

Does Xu Cong care? Attending the National Revision Conference, he was very uninterested, let alone an exam.

Xu Cong hurriedly asked the senior at the door: "Don't blow, let's get down to business, what's the question?"

"Feng Nianchang said you are good at physics, I have a question I want to ask. In addition, I also want to understand your answering skills!"

This is a clever person, people don't have any problems, ask how to learn!

Maybe this is the difference between a genius Xueba and ordinary students. Liu Yixiang handed the question to Xu Cong.

Problem: Two small balls a and b, which can be regarded as mass points, are connected by a light rod to prevent them from being in a smooth hemisphere.

It is known that the mass ratio of small balls a and b is √3:1, and the degree of thinness is √2 times the radius of the spherical surface.

When the two balls are in equilibrium, what is the angle between the thin rod and the horizontal plane?

A.45

B.30

C.22.5

D.15

There are not many words in the question, and the picture given is very simple. It is a semicircle with a pole and two points ab in the two sections of the pole.

Xu Cong watched, and the roommates also came to look at the question.

In the next second, the roommates clamped their eyes and said one after another: "Spicy eyes! I can't understand at all!"

"This is the subject of the third year of high school. I'll go, it's too difficult!"

"What the hell? I know the truth! I can understand the topic, but...I just can't do it!"

But that's it?

I can understand everything, but I can't. Liu Yixiang looked at Xu Cong.

Xu Cong spoke slowly after reading it, "Since you want to learn methods and ideas, you want to talk about your ideas."

As a student master, Liu Yixiang naturally has his own way of solving problems. He took out his pen and paper, and wrote while talking.

"Assuming that the elastic force of the thin rod on the two balls is T, the force of the small balls a and b is shown in the figure, where the elastic direction of the ball facing the two balls points to the center of the circle, that is:

Therefore, the direction of FNa is upward and rightward, that is, the direction of β1=90-45-0=45-FNb is upward and leftward, that is, β2=90-(45-0)=45=0. Both balls are subject to gravity and a thin rod. The effect of the elastic force of and the elastic force of the spherical surface, cross 0 to make a vertical line to intersect ab at the point c, set the radius of the spherical surface to R, then abc is similar to the left force triangle; abc and the right force triangle are like; from the geometric relationship These are available. "

Liu Yixiang wrote densely on the paper, and there were a lot of formulas.

"In the end, we get a=45, and then..."

Not only there are so many formulas and equations, but also diagrams to be made! Very detailed diagrams!

If this is an exam, a set of multiple-choice questions, it will take ten minutes to take the exam. What else?

The roommates onlookers found it difficult just to see Liu Yixiang's problem-solving ideas!

"Give it to me, I must give up!"

Liu Yixiang smiled bitterly, "It's me instead, I also gave up during the exam! That's why I came to ask..."

Look at Xu Cong!

Huh huh!

The dormitory is quiet, with a pair of eyes staring at Xu Cong
