Since Gong Yu, Mo Yun and Zuo Yunfeng formed a study group, Gong Yu and Zuo Yunfeng's lunch was basically solved at Mo Yun's house.

Today noon is no exception.

The three of them had lunch while tutoring, and then went to school together.

Afternoon classes are relatively relaxed.

Because it was the critical moment of the third year of junior high school, the physical education class was changed to a self-study class.

After reading the book for a while, Gong Yu began to tutor Zuo Yunfeng.

At first, Zuo Yunfeng was worried that Gong Yu hadn't come to school for a week, and the course would definitely be left behind, and there was no way to tutor him for the latest course.

But he didn't want to, Gong Yu was not affected in any way, and when he talked about the topic, it was as if he had already done it a thousand times.

What's even more terrifying is that Gong Yu always likes to simplify complex topics, which makes Zuo Yunfeng feel like he is sudden.

Soon, the bell rang for the end of school.

As soon as the students heard the bell, they flew to the open sky like birds released from their cages, breathing free air.

Today's classroom duty students happened to be Gong Yu and Zuo Yunfeng's turn, so within ten minutes, there were only two of them left in the classroom.

After a while, Mo Yun also walked in with his schoolbag on his back, skillfully took out his textbook, and began to listen to Gong Yu's lecture seriously.

When Liu Xiaodan entered the classroom, he saw such a scene.

At first, she thought that Gong Yu wanted to ask Zuo Yunfeng and Mo Yun to help her with her homework, but when she heard that Gong Yu was actually giving a lecture to the two, she couldn't help but be surprised.

What surprised her even more was that Gong Yu explained exactly the topic that she had been absent from class for a week.

It seems that Gong Yu said that she brought her textbooks to Guishi and that she didn't need tutoring.

Gong Yu was able to read a book by himself without a teacher's explanation?

That's the standard of genius!

When Liu Xiaodan thought that he had taught a genius student, his heart beat faster with excitement, and he couldn't restrain his excitement.

Subconsciously, she didn't bother Gong Yu's explanation, but stood quietly at the door and listened, wanting to hear how deep Gong Yu had on the topic.

Hearing this, Liu Xiaodan's mood became even more excited.

Gong Yu not only knows the knowledge in the textbook well, but can even draw inferences from one topic to the other for Zuo Yunfeng and Mo Yun.

And Gong Yu's solution ideas also surprised Liu Xiaodan.

She really didn't think of such a way to solve the problem.

In fact, Gong Yu only used the Olympiad that was respected in later generations to solve the problem.

Originally, Liu Xiaodan thought that Gong Yu would give the answer directly, but Gong Yu patiently induced the two of them step by step to go to the correct way of solving the problem, let them think for themselves, and finally came up with the answer.

This kind of teaching method makes Liu Xiaodan appreciate it very much.

It not only improves the enthusiasm of students to participate, but also allows everyone to use their brains to think, and finally transform knowledge into their own things, which can be used flexibly.

What makes Liu Xiaodan even more unbelievable is that Gong Yu not only explained the knowledge he had already learned, but even the knowledge he did not learn in the future could be applied to the current topic.

Even, when Gong Yu was explaining an unfamiliar theory, Liu Xiaodan actually found that Gong Yu was explaining the knowledge that would be taught in the next semester.

Gong Yu has already finished studying the textbooks for the next semester.
