"Nowhere can you do it."

I don’t know if it was Xu Sheng’s illusion, but the boy’s speech was clearly the same tone, but he didn’t sound that cold.

Xu Sheng pointed to the first key question.

In addition to the knowledge points I learned in my second year of high school, this question is indeed combined with the formula theorems learned in the first year of high school, which is a comprehensive question type. Shao Zhan took out a piece of calculation paper from the side, stacked it on the question list, and then wrote down Gao's theorem: "I'll push it, you can watch it."

He said, drawing the axis on the paper.

"The mathematical definition of a function is to give a non-empty set of numbers a," Shao Zhan wrote an a on the axis, "Imposing the corresponding rule f to a, denoting as f(a)."

Shao Zhan starts with the basics.

Xu Sheng thought that Shao Zhan would be like him when he gave a question, regardless of whether others could understand it or not. No matter how unkind he looked, he didn't seem to be able to explain the question carefully.

However, unexpectedly, Shao Zhan had a clear idea of ​​the topic and did not say a single nonsense. He even stopped and asked him after he finished a key point: "Do you understand?"

Xu Sheng actually understood, but he really lacked enthusiasm for learning. Even if he listened to what Shao Zhan said, he was still in a state of not being able to do anything, and did not miss any opportunity to temporarily escape from the state of learning.

He supported his chin with one hand, and Shao Zhan's natural and oppressive face appeared a little dispersed at this moment. Xu Sheng leaned over slightly and asked in a long tone: "Teacher, if I don't understand, can you say it again?"

This sentence is so meaningless by the teacher.

The description of Xu Sheng as a friend of a woman is not accurate. As long as he is not serious, he can easily create some illusion. For example, at this moment, he looks like an absent-minded student who is trying to tease the bad students of the tutor.

"If you understand, do it yourself."

Shao Zhan ignored him and said coldly: "Read the question, don't look at me."

"You don't look at me," Xu Sheng said with a pen hooked up, "How do you know I'm looking at you?"

As long as you can not talk about learning, Xu Sheng can tell any lies.

"If you have a cold face like this, your learning efficiency will be reduced... Do you have to take care of the students' mood?"

"Or let's talk about something else," Xu Sheng said again, "If there is no partner, what about the person you like."

The cicadas outside the window were gradually weakening, and the lights were turned off. The corridor in the dormitory building was extremely quiet. Shao Zhan pinched his pen, looked cold and didn't say anything. He looked up and saw that he only met a pair of eyes with a slightly smile.

Shao Zhan was stunned for a moment.

At this moment, the time just jumped to the 10 o'clock lights, and the whole building suddenly fell into darkness.

Xu Shengxin said that the lights were turned off, and the tutoring time should be over. He felt the darkness and reached out to close the title. However, after the lights were turned off, the room was really dark and could not adapt for a while. He couldn't see anything in front of him, so he grabbed Shao Zhan's hand directly.

It was obviously his own hand, but it seemed to have a completely different temperature from him.

Until the darkness, a cold voice asked, "Have you touched enough?"
