Zheng Hongjie: ......

Students: ......

"It's all classmates, can you save some face?" Zheng Hongjie whispered.

"That's not good, I'll save face for you, did you save face for me before? Eat it, maybe after eating, you will open up your skills to do better, and you will thank me when the time comes. Sui Xiaotian sneered.

Zheng Hongjie glared at Sui Xiaotian angrily, nodded and said, "Okay, I'll eat, you wait for me." ”

"I'll wait, hurry." Sui Xiaotian hugged his shoulders and prepared to watch a good show, I, Huang Liang, am not afraid, will I be afraid of you, this guy?

"This person really does what he says, domineering."

"It seems that the most offended thing in our school is Sui Xiaotian."

"yes, yes."

"Don't say it, hurry, find a good position, get ready to watch the play, and eat the test papers!"

All the students were ready to watch the play at this time, and everyone had schadenfreude on their faces.

Looking at the roll in front of him, Zheng Hongjie was ruthless, directly tore off a piece and stuffed it into his mouth, and then began to chew.

When everyone saw that he really ate the rolls, they all admired him.

"Take your time, don't choke." Sui Xiaotian watched him try to eat the rolls and handed over a glass of water.

The guy who fell into the well!

However, Zheng Hongjie still took the glass of water with red eyes, and the rolls were indeed too unpalatable.

In this way, during a recess, Zheng Hongjie ate all the rolls. Sui Xiaotian watched him finish eating with a smile, patted him on the shoulder and said, "If you want to make trouble with my brother, come here, but you have to think about it, next time it won't be as simple as eating rolls." ”

Many students looked at Zheng Hongjie and their hearts were full of sympathy.

Not only do you have to eat the rolls, but you also have to be ridiculed, the point is that you also lost to the worst scumbag in the class, if I really find a crack to drill down.

But looking at Sui Xiaotian again, many students feel that this person is really hidden. And he will be revenged, and he must not be offended in the future.

Zheng Hongjie glared at Sui Xiaotian at this time and said, "Don't worry, I will definitely think about it next time." I didn't expect you guy to cheat, it's so shameful. ”

His words also expressed the thoughts of many students, but many students also felt that such grades could not be made by cheating. But thinking of such an incredible thing that a crane tail suddenly scored so high, they had to doubt it.

"What if I wasn't cheating."

"If you're not cheating, then I'll call you grandpa."

"You really don't want to die in the heart of the Yellow River." Sui Xiaotian said with a smile.

"You trash, dare you prove it." At this time, Zheng Hongjie was like a red-eyed gambler who wanted to turn over the book, and he said with a stalk on his neck.

"Then you can wait and call me grandpa in a moment." Sui Xiaotian turned around and returned to his seat, just as the class bell rang.

The head teacher walked into the classroom with the paper and announced the start of the class with a bang.

"Please open the paper, and we will explain the big part of the paper in this lesson."

The head teacher opened the paper, glanced at the big question, thought about it and said: "Actually, the best answer in this physics paper is not Ding Xinran, but Sui Xiaotian, your answer to the last big question is very novel." ”

After hearing this, everyone looked at Sui Xiaotian with incredible eyes again. Especially Ding Xinran, and Sui Xiaotian looked at these gazes, and his heart was naturally very comfortable.

"Thank you, teacher, for the compliment." Sui Xiaotian smiled shyly.

"But I still want to ask Sui Xiaotian first, is your result really answered?" The head teacher asked with a pleasant face.

It is not easy to produce a second champion seedling in the class, but unfortunately, this Sui Xiaotian has too much moisture, even he has to wonder if Sui Xiaotian is cheating.

"Yes, teacher." Sui Xiaotian stood up and said directly: "That's it, teacher, I'll explain the last few questions of the physics paper this time." ”

Don't you believe me, this time, I'll use my strength to speak.

Are your faces ready?

The head teacher was obviously stunned, and then he nodded and said, "Yes, if you make a mistake, I will correct it." ”

It's not that there are no classmates in the class who come up to talk about the topic, in fact, Ding Xinran, as the first place in the class, often comes to the stage to talk about the papers, and now he is almost as good as the teacher.

And Sui Xiaotian actually recommended himself, and the head teacher naturally couldn't ask for it. He also wanted to know if Sui Xiaotian really had this strength.

Sui Xiaotian walked up to the front desk, looked at the complicated eyes of all the classmates and smiled, and then picked up the chalk.

"Please take a look at question 18, I believe everyone finds it more difficult. But don't be afraid, there are many ...... for this problem" Sui Xiaotian was walking on the podium, but he didn't use psychics.

In fact, all the test questions and solutions in this paper, even if you don't use the ghost Zhou Yao, Sui Xiaotian can answer them all.

Because when the psychic is over, the knowledge left by Zhou Yao will become his own.

"There is a pair of parallel metal plates in the vacuum, 6.2cm apart, and the potential difference between the two plates is 90V. What is the kinetic energy of the divalent oxygen ions that accelerate from rest to the other? ”

Sui Xiaotian began to answer on the blackboard with chalk: "First, let's use the first method, Newton's second law:

F = ma;

E = U\/d;

F =-qE; (q& amp; amp; lt; 0)

v^2 = 2ad;

(E is the field strength!) )

Find the kinetic energy (mv^2)\/2 =-qU;

F =-qE; Then we ask for strength.

E = U\/d; Then ask for field strength.

Ft = mv;

It's over, you need t to find v to find kinetic energy...

How to find t? We know that ions move in a straight line with uniform acceleration, and we know the displacement, according to s = (1\/2)at^2

Asking for acceleration,It's not about using Niu Er to find acceleration.。。。 ”

Although all the students listened carefully, they were all dumbfounded.

This guy can really make it!

After answering Sui Xiaotian, he said: "Of course, this is the first solution, let's take a look at the simpler one." ”

"From the point of view of energy, energy is conserved, and electric potential energy is converted into kinetic energy.

That is: initial kinetic energy + initial potential energy = final kinetic energy + final potential energy.

0+0=E+qU;

E=-qU; ……”

Now all the students have one thought left, that is, this guy is hanging!

Looking at Sui Xiaotian on the stage, the head teacher's heart turned upside down.

If he had some doubts before, now there is not the slightest doubt. Sui Xiaotian may still have some youth in explanation, but his knowledge does not have any moisture.

These questions were all made by himself. He even asked Sui Xiaotian some very difficult questions, and Sui Xiaotian answered them all.

"Genius, or monster?" The head teacher didn't know what to say. Sui Xiaotian began to talk about other questions again, and they were completely standard answers.

Many students also can't understand how this usually inconspicuous scumbag became the current top student?

Of course, there is a person's heart at this time, but it is getting colder and colder.

And his face is getting paler and paler, but this person is Zheng Hongjie.

Sui Xiaotian used his ability to beat his cheating theory beyond recognition, and every time he explained a question, his face would turn red.

And now, Sui Xiaotian has spoken six multiple-choice questions and several big questions, and his heart has sunk to the bottom of the sea.

Do you really want to call him grandpa?

Of course, there is another person, whose feelings have become extremely complicated.

She had never cared about Sui Xiaotian before, and she hadn't even looked at him. But today, Sui Xiaotian showed an excellent side in front of her, and it can be said that this man is a blockbuster.

Similarly, she also knew why Sui Xiaotian made that bet with her. If his other grades are not too bad, it is enough to be admitted to Yenching University!

"This damn liar!" Thinking that Sui Xiaotian deceived her about the gambling contract, she was going to become his girlfriend after Sui Xiaotian was admitted to Yenching University, she blushed for a while.

Yourself, why did you fall for it?

It's just that who would have thought that Sui Xiaotian, who was just a scumbag at the time, would have a counterattack one day?

Standing in front of the stage at this time is Sui Xiaotian, a scholar, probably, he is really different. Ding Xinran's eyes were complicated, looking at Sui Xiaotian's expression, he was no longer all disgusted.

Sui Xiaotian didn't stand on the stage for too long, and it was over after doing a few difficult problems, after all, he had already proved that he was absolutely not cheating, and slapped those who thought he was cheating in the face.

When he walked down, the head teacher nodded and said, "Very well done." ”

God is pitiful, Sui Xiaotian has been in high school for three years and has never been praised by any teacher, but this time, he finally got the teacher's approval.
