Zuo Yunfeng also felt Liu Xiaodan's gaze.

At first, he thought that Liu Xiaodan was staring at him, and he was so frightened that he kept checking in his heart whether he had made a big mistake.

When he knew that Liu Xiaodan saw Gong Yu, not him, he was secretly relieved.

I'm scared to death.

"Brother Yu, you disappeared for three months at once, it seems that you were remembered by Teacher Liu!"

Zuo Yunfeng's gloating voice made Gong Yu helpless.

She didn't want to disappear for three months at once!

But even if she disappeared for three months, Liu Xiaodan didn't need to stare at her like this, right?

It made her look like a fugitive from prison.

The classmates in the class all felt Liu Xiaodan's strange gaze, and they all looked in the direction of Gong Yu, as if the words "ask for more blessings" were written in their eyes.

Liu Xiaodan has been extremely strict recently, as if he had been stimulated, forcing them out of breath.

It's good now.

Gong Yu's appearance diverted Liu Xiaodan's attention, and they were finally able to breathe a little fresh air.

"Jingle bell—"

The melodious bell rang for the end of class, and Liu Xiaodan seemed to be a machine that had been turned off, and instantly stopped the sound of the lecture.

She casually said that she was out of class, and called Gong Yu to the corridor.

"Brother Yu, take care."

Zuo Yunfeng patted Gong Yu's shoulder, causing Gong Yu to cry and laugh.

in the hallway.

"Teacher Liu, I'm sorry, I suddenly took so many days off......"

Before Gong Yu's words were finished, Liu Xiaodan suddenly asked, "Have you caught up with your learning progress?" ”

"Yesterday, I finished reading Zuo Yunfeng's class notes."

"Then you'll take the next class for me."

“……”

Teacher, is it so casual?

Not allowing Gong Yu to refuse, Liu Xiaodan had already made a decision and patted Gong Yu's hand, "There are still a few minutes to go to class, you go in first to prepare and think about what to say." ”

Gong Yu: "......"

Mr. Liu, do you know that it is only a few minutes?

What did she think about these few minutes?

Catch the ducks on the shelves, and don't bring them so fast!

Gong Yu complained in his heart, but he didn't refuse, turned around and went back to the classroom.

Before turning around, she subconsciously glanced at Liu Xiaodan more.

Liu Xiaodan's face seemed to be a little abnormal.

The weather in May was not too hot, but Liu Xiaodan's forehead was covered with fine beads of sweat, as if she had exhausted all her energy after teaching a class.

Gong Yu was puzzled and returned to his seat.

Soon, the class bell rang again.

Under the doubts of all the classmates, Liu Xiaodan sat in Gong Yu's position, and Gong Yu took the textbook and went to the podium.

Calm, calm, without a trace of timidity.

This courage is not at all like a student who is on the podium for the first time, but like a senior professor who gives lectures all year round, which makes people feel awe.

However, Gong Yu hasn't come to a few classes since school started, can she really give a lecture?

What's more, Gong Yu also disappeared for three months.

She, can she really do it?

Although the doubts of the classmates were not spoken, the skeptical eyes had already explained everything.

If it were someone else, he would definitely be so weak that he couldn't even speak.

But Gong Yu not only did not feel empty-hearted, but confidently opened the book and wrote down the upcoming lesson on the blackboard.

【Quadratic Functions】

"Quadratic functions? Isn't this what Mr. Liu is preparing for the next lesson? ”
