With a light cough from Mr. Cao Jiuzhang, the advanced mathematics class began.

Speaking of which, Cao Jiuzhang's class is still good, and this teacher doesn't like to talk nonsense, everything he talks about is full of dry goods, and the board books are also the essence of the essence.

Why, this is either the journalism department or the foreign language department, and the level of mathematics is all scum, which really lives up to the high level of this old pedant.

Knowing that Cao Jiuzhang was not easy to deal with, the classmates present were taking notes carefully. After a class, everyone's notes were memorized, although everyone knows the words written on the notes, but what exactly they mean, only God knows.

But there are always special people, there is only one person in this classroom, and he didn't even write a word, this person is Lu Chen.

Halfway through the second class, Shen Xiyan finally couldn't help but be curious, and asked in a low voice, "Lu Chen, why don't you take notes?"

"You see you've all taken notes, isn't it a waste for me to take notes again? ”

Shen Xiyan glanced at him angrily, "You dream, I'm not going to show you!"

"That's right...... Why did WeChat block me?" Lu Chen asked taking the opportunity.

"You dead pervert~ pervert, what's wrong with me blocking you?" Shen Xiyan said in a low voice, "I'll tell you, don't think about the best show, I'll let everyone vote for the program of the girls in our class! People from other departments must vote for their own people! You just wait to learn how to bark ......"

Shen Xiyan was smiling proudly, and suddenly felt that something was wrong, why was she so quiet? She suddenly found that Lu Chen was already sitting upright, her eyes looked at the podium, and an ominous feeling immediately enveloped her whole body. She slowly raised her head and saw that Ximen Fuxue was looking at her with a serious face, and her blood was about to coagulate for a while.

Ximen Fuxue put down the chalk in his hand and said word by word: "This female classmate, please stand up." ”

Shen Xiyan looked embarrassed, and slowly stood up under the pitying gaze of more than a hundred people, his face was already red to the base of his neck.

Some of the boys began to mumble under their breath.

"Look, the school girl is going to be unlucky......"

"Who's going to save my school girl?"

"Roll rough, the school flower is my ......"

……

Lu Chen was about to see the joke, when suddenly Cao Jiuzhang looked at him, "And this male classmate, you also stand up." ”

Lu Chen secretly sighed, so he could only stand up, and smiled at the West Gate Blowing Snow without knowing whether he was alive or dead, "Teacher, is there something wrong with you?"

……

As soon as the words came out, the whole classroom was quiet, and everyone looked at him like a monster, this buddy is a cow, what a cow! Dare to blow snow and stab with Simon! His advanced mathematics is definitely hanging, I guess I won't want to pass it in my life!

Cao Jiuzhang was also stunned for a moment, he hadn't seen such a calm student in front of him for at least ten years.

Coughing lightly, Cao Jiuzhang said, "Tell you to get up, of course there's something!"

"Teacher, you say, I will definitely help if I can......"

Wow......

Everyone laughed, this kid's brain is in water!

Jin Xin and Zhang Jianing next to Lu Chen were stupid, Jin Xin tugged at Lu Chen's clothes vigorously, he knew that Lu Chen was more hanging, but big brother, don't hang yourself in front of Ximen Blowing Snow, he is an old devil who can't see blood!

Shen Xiyan's heart was even more cold, he was really miserable by Lu Chen today! It's not a good thing to encounter this dead metamorphosis, and he still has this attitude towards Cao Jiuzhang now, if you die, you will die, don't pull Miss Ben with you!

Cao Jiuzhang's expression became more serious, and the murderous aura in his eyes had penetrated the thick reading glasses and shrouded Lu Chen's body.

"If you don't think math class is useful, you can leave the classroom now and don't have to come back to it in the future!"

The death-like silence lasted for more than ten seconds, and this sentence was equivalent to a death sentence for the math scores of the two. Everyone's eyes are even more pitiful, some boys can't help but gloat, they deserve it, boy, who let you sit with the school girl!

Finally, Shen Xiyan couldn't help it, and said timidly: "Teacher Cao, I'm sorry, we ...... just now"

"I was chatting just now!" Cao Jiuzhang said word by word, "I can see it clearly!"

"I ......" Shen Xiyan was speechless, and began to think about how to ask his father for help and let him come forward to settle this matter.

Lu Chen suddenly smiled, and said with a relaxed face: "Teacher, you misunderstood! We didn't chat! You spoke so well, we didn't have the heart to chat at all!"

"Classmate, what is your name, is it from the Department of Foreign Languages or the Department of Journalism?" The anger in Cao Jiuzhang's eyes was even heavier, this student dared to ridicule the teacher to his face?

The classroom was quieter, and everyone thought that this boy was finished, Cao Jiuzhang was a veteran figure of Haidong University, in this case, he asked the boy about the details, obviously he didn't plan to give up, what would be waiting for this boy?

You must know that Cao Jiuzhang really expelled a student who didn't know how to advance or retreat, and it is said that the student was still the child of a certain leader in Haidong City, but he still left Haidong University in disgrace.

"Brother Chen!" Jin Xin tugged Lu Chen's arm hard below, and said in a low voice, "Please stop playing, okay?

Shen Xiyan also realized that something was wrong, and she quietly stepped on Lu Chen fiercely below, hoping that he would shut up quickly.

Lu Chen didn't seem to notice it at all, and continued: "Teacher Cao, I'm Lu Chen from the Department of Foreign Languages! Seriously, your class is very good, just like the concept of limits you just talked about, that is no longer imparting knowledge, but talking about philosophy, or world view! In fact, I have always believed that mathematics is the ultimate discipline in this world, the most abstract and incisive understanding of this world, and the basic tool of all sciences. Now everyone is familiar with the names of Newton, Einstein, Pohr, Planck, and other physicists, but they don't know that if there is no mathematics, they will not be able to play any of them! What is the name of the book that records the famous Newton's three laws? It is called "The Mathematical Principles of Natural Philosophy?" One can imagine the importance of mathematics!

The classroom has been quiet and you can hear a needle falling on the ground, everyone is looking at Lu Chen like a monster, I will strangle it...... Isn't that crazy?

Cao Jiuzhang was also taken by Lu Chen to distort his rhythm, he couldn't figure out if this boy was deliberately making trouble, but what Lu Chen said really spoke to Cao Jiuzhang's heart. Having studied mathematics for most of his life, he certainly thinks that mathematics is the most beautiful subject.

Then, Lu Chen changed his words and said to Cao Jiuzhang's class, "In the last lesson, you introduced the concept of limit from the paradox of tortoise and rabbit racing, which is indeed very appropriate, and you emphasized the ...... about the limit theorem."

Lu Chen crackled like a talk show and began to talk endlessly, and now Cao Jiuzhang was really stunned, because Lu Chen actually synthesized the key points he talked about and said them completely, without missing any details, and finally, when Cao Jiuzhang stopped the lecture and asked Shen Xiyan to stand up, Lu Chen stopped talking.

He smiled faintly and said, "Actually, we really didn't talk just now, we just discussed what you talked about a little, and the girl next to me was too slow to take notes, and she didn't remember them all, so she was asking me ......."
