However, when Zhan Fei was smiling, countless people's eyes were focused on him, and Guo Xin and Zhou Tai both sweated for Zhan Fei, this is a black face class, black face has always been black-faced, many people in the class are very afraid of black face, Zhan Fei actually laughed at the climax of Black Face's speech, this is simply challenging the limit of Black Face's patience!

And after seven or eight seconds, Zhanfei found that the noisy classroom suddenly quieted down, everyone looked at him, and then he looked up at the podium, and the black face also stopped lecturing, with his hands behind his back, looking at Zhanfei with interest.

This time, Zhanfei finally knew what he had done, hurriedly restrained the smile on his face, and looked at Hei Mian cautiously, and Hei Mian also said slowly: "This classmate, I want to ask you, is my lecture so funny?" ”

Zhan Fei knew that this was the prelude to the coming storm, and he immediately stood up straight, and then said: "Sorry teacher, I was excited for a while, please forgive the teacher!" ”

Black Face listened and said, "Excited for a while? Can you tell me about the excitation method? ”

Heimian said, holding the blackboard eraser in his hand, and then slapped it on the table, and if it was usual, I am afraid that Zhanfei's body rhythm would be like that table, and he would be scared directly, but this time, he is not afraid, all the students who are afraid of the teacher are poor students!

All students who study well are the objects of the teacher's key care, and the treatment of poor students in all aspects is different, Zhanfei has experienced the treatment of excellent students before the university, and when he comes to the university, he has also experienced the treatment of poor students, before, he is a poor student, so in the face of black-faced teachers, he will tremble with fear.

But now that his intelligence has soared, he can proudly say that I will be an honor student! Facing the teacher, he was naturally not afraid, but in fact, what Hei Mian said before was written on the blackboard, and Zhanfei only glanced at it and saw it clearly.

Originally, his eyes were slightly short-sighted, and it was not easy to see the blackboard clearly when he sat in his position, but his agility value increased a little, and Zhanfei's vision returned to normal, so he could see so clearly.

Then, Zhanfei said: "Because the derivation of the coordinate parameter equation is really interesting, I never understood before, what kind of point vector parameter of the straight line L will be..."

Next, Zhanfei said a difficult point that the black side on the blackboard was talking about very fluently, and the black side of this difficulty was going to be talked about in two classes, because this knowledge point has extremely high requirements for three-dimensional thinking ability and logical deduction ability, and it is extremely difficult for students to master.

Even if it is rote memorization, it is difficult for most students to master, and this knowledge point is difficult and focused, so he is ready to take out a large class to talk about it, and Zhanfei's laughter before did make the black face very angry, if Zhanfei can't give a reasonable reason, then he is also ready to make an example of the monkey, deducting the usual points of Zhanfei.

After all, if Zhanfei listened carefully to the class, he was on the podium, standing tall and seeing far away, so Zhanfei's performance throughout the class, he knew everything, basically except for wandering his mind or sleeping, but he didn't expect that this student's answer was completely unexpected by him.

This poor student has thoroughly understood and understood this knowledge point, to know the way, until now, Xu Jiaorong, who is the best student in the entire department, is full of doubts and has not been able to understand it at all!

But Zhanfei has already understood it, he can understand that people who study mathematics, after being trapped by a difficult problem, and then suddenly solve the problem, that kind of ecstasy and excitement is indeed difficult to suppress, and it is understandable that Da Lu laughed.

And what surprised Hei Mian even more was that Zhanfei explained this knowledge difficulty in simple terms in his own words, and the process of this explanation was even better than what his professional tutor said.

At least, after Zhanfei finished speaking, many students who were still in a daze showed a sudden expression, they had spoken for a full thirty minutes before, it was better for Zhanfei to give a brief description of five or six minutes! Suddenly, Heimian's opinion of Zhanfei also changed greatly, this is a genius student!

No matter which teacher has a very friendly attitude towards gifted students, as for the situation of Zhanfei's distraction in sleep, it was completely ignored by the black face, and people slept and wandered, and they thoroughly analyzed the difficulties that you couldn't understand for a long time, this kind of student, is it necessary to study seriously like an ordinary student?

Genius has to be treated specially, so next, Hei Mian said: "Very good talk, what is your name, classmate?" Zhanfei listened and was stunned for a moment before he spoke: "My name is Zhanfei, teacher." ”

"Okay, Zhanfei, sit down."

And Zhanfei listened and sat down, at this moment, the students in the class looked at Zhanfei in surprise, what kind of character is Zhanfei, who doesn't know what to do? He has never listened carefully to a class, and he relies on copying every time he takes the exam, but he has mastered such a difficult knowledge so quickly?

Even Han Ling Han Dahua, who was sitting next to Zhan Fei, temporarily forgot about Zhan Fei's obscene behavior before, and looked at Zhan Fei with a surprised look, while the fat man Zhou Tai stared at Zhan Fei carefully, and then said, "You kid, what kind of elixir have you eaten?" How did you become so powerful all of a sudden? ”

Zhanfei listened and said, "What do you know, my brother is usually just a little low-key, but in fact, my brother is a very awesome character!" ”

When Zhou Tai heard this, he directly patted Zhanfei's arm and said, "Pull it down!" ”

Because of Zhanfei's previous explanation, Heimian was originally going to spend two classes to finish a key point and add difficulty, and he finished it in one class, and the effect was much better than he expected, but in the second class, Heimian directly assigned a question, so that everyone tried to apply the knowledge point in the previous class.

After all, understanding and mastering are two concepts, and Heimian also wants to strike while the iron is hot, so that everyone can thoroughly grasp this knowledge point, such a simple topic, Zhan Fei glanced at it and threw it aside, such a simple topic, he was too lazy to do it, for him, doing this question, it was as simple as doing one plus one equals several, and he naturally disdained to do it.

As for the words of Zhou Tai and others, like Zhanfei, they also threw the question aside and played with their mobile phones, of course, they didn't disdain to do it, but they didn't know how to do it at all, Zhanfei is a major, there are more boys and fewer girls, and most of the girls are more obedient and well-behaved than boys.

Han Ling was the same, tilting his head, biting the cap of the pen, his brain was constantly running there, trying to find a solution to the problem, but it was really not easy to do this problem for a while and a half, so after twenty minutes, Han Ling had no clue.
