How can it not be dusty

82,

Although the back hole was licked and wiped, He Zhan stood up as soon as he put on his pants, and then flowed down the buttocks to his thighs.

He Zhan pursed his lips, "Professor Xu, all your semen has flowed out."

Xu Weichen took the lesson plans and the USB flash drive to go to class, kissed He Zhan before opening the door, and said, "Hey, suck it back by yourself."

He Zhan followed Xu Weichen out the door, lowered his voice and said, "Xu Weichen, you are really coquettish."

Xu Weichen raised his eyebrows slightly, "I hold a grudge, please be ready to answer questions in class later."

Because of this sentence, He Zhan didn't dare to flirt with the professor's face the whole class.

In order to avoid suspicion, He Zhan entered the classroom. He was afraid that Xu Weichen would directly ask him to answer the questions. He opened the book and made up the knowledge points of the previous class. He didn't notice when Xu Weichen came in.

When the class bell rang, he raised his head from the book and looked at the podium.

Professor Xu, who was fucking him a moment ago until he was sweating all over, changed into a meticulous, gentle and steady face in the blink of an eye. There was not a single wrinkle on his shirt, and his tie was neatly tied. Only He Zhan knew this. How much time was spent ironing clothes before they shipped out of the office.

He Zhan was ready to be called to the podium by Xu Weichen alone to hand over his mobile phone. Who knew that Xu Weichen turned on the microphone and said, "I would like to inform all students that from now on, there will be no roll call in the microeconomics class, and there is no need to hand in your mobile phone. Do what you want in class, and students who want to leave the classroom, please leave within 5 minutes."

He Zhan thought that Xu Weichen was going to do something else to harm his students, but he didn't expect that after Xu Weichen finished speaking, he opened the PPT and prepared to start the lecture.

There was a moment of silence in the classroom, and then bursts of heated discussions erupted.

Xu Weichen tapped the blackboard with his fingers, and said into the microphone: "But I think you should abide by the most basic classroom order. If you are not interested in this course, you can leave through the back door."

Of course, no one would go out without a desire to survive, but there were also several people who looked at the back door frequently, as if they wanted to leave but dared not.

Xu Weichen added another sentence: "Students who leave the classroom are anonymous, they can rejoin the classroom at any time, and they will still have a basic score. They can take the exam at the end of the semester. Thank you for your active participation in the first five weeks. See you in the exam room at the end of the semester."

Universities are not like middle and high schools. The deterrent effect of teachers on students is limited to final exams and grade points. The professors have said so, and a few brave ones really went out through the back door.

He Zhan kept staring at the back door, either because he wanted to leave, or because he couldn't figure out why Xu Weichen would do this.

Skipping class is anonymous and still gets the usual points. Isn't waiting for class to become a one-man show?

Xu Weichen raised his hand and glanced at his watch, and said, "There are still 3 minutes, and we will register after 3 minutes."

He Zhan watched the people in the classroom leave one after another. Human nature is like this. Some things are done by one person and dare not be done by a group of people. Fifty people.

Among the fifty or so people, I don't know how many are still watching, and how many are purely admiring Xu Weichen's face. There are very few people who really want to attend the class.

Xu Weichen finally chuckled, "Thank you for your recognition of my personal charm, and I'm glad that you have recognized the charm of economics and are able to gain a deeper understanding of economic laws and understand the essence of economic phenomena."

He Zhan looked at Xu Weichen in a daze, feeling sorry for him for some reason.

Seeing my students slip away one by one, I should feel very uncomfortable...

Xu Weichen said he was going to get up and answer the question, so he was the first one to hit him.

The class officially started. Xu Weichen called his name in Chinese and asked him in English: "Student He Zhan, Please recall the law of diminishing marginal utility that welcome in last week's class and explain in last week's class and explain in popular way." )

He Zhan stood up in shock, and asked Xu Weichen, "Professor, can I not use English?"

The rest of the classroom gasped twice in unison. The first gasp was because He Zhan didn't leave, and the second gasp was because he didn't leave, as if he stayed to make trouble for the professor.

Xu Weichen raised his eyebrows, "You can do whatever you want."

Like an artificial intelligence, He Zhan recited all the relevant knowledge about the law of diminishing marginal utility without emotion. After answering, Xu Weichen didn't let him sit down, but said: "Student He Zhan, you are very good at memorizing. "

He continued: "However, the study of economics should not be formulaic. I can explain the law of diminishing marginal utility more intuitively."

He Zhan also raised his eyebrows like him, "Then ask the professor to guide you?"

Xu Weichen looked deeply into He Zhan's eyes, and said slowly, "Diminishing marginal utility can also be explained by physiological phenomena. Satisfaction makes people mentally excited, but repeating the same stimulus will make people's excitement decrease."

He did it on purpose, He Zhan was sure, he deliberately emphasized "satisfaction", "stimulation" and "excitement".

He Zhan is a shameless old man who uses the class time to talk flirtatiously. He Zhan is not willing to be molested by him, so he deliberately finds fault: "Professor, what you say is too abstract, I don't understand."

Xu Weichen walked in front of him slowly, and said softly: "To give an easy-to-understand example, if it's the first time I associate with my peers, I will feel excited, but after continuously interacting with different peers, this incident will bring more excitement. The level of satisfaction given to me will decrease.”

Xu Weichen's voice became smaller and smaller, until in the end only He Zhan could hear him, "So, I will look forward to falling in love with a kid like He Zhanzhan."

The others sat too far away, couldn't hear what Xu Weichen said at the end, they just burst out laughing at the example Professor Xu gave.

He Zhan sat down and didn't listen to anything for half the class.
