Ever since Gong Yu, Mo Yun and Zuo Yunfeng formed a study group, Gong Yu and Zuo Yunfeng basically had their lunch at Mo Yun's house.

Today at noon is no exception.

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

The afternoon classes are relatively easy.

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

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

At first, Zuo Yunfeng was worried that Gong Yu had not come to school for a week and must have fallen behind in his studies, so there was no way to help him catch up on the recent courses.

But unexpectedly, Gong Yu was not affected at all. She spoke about the questions as if she had done them thousands of times before.

What’s even more frightening is that Gong Yu always likes to simplify complex questions, giving Zuo Yunfeng a sense of sudden enlightenment.

Soon, the school bell rang.

As soon as the students heard the bell, they ran towards the vast sky like birds released from a cage, breathing the free air.

Today's classroom monitors happened to be Gong Yu and Zuo Yunfeng, so within ten minutes, they were the only two left in the classroom.

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

When Liu Xiaodan entered the classroom, she saw this scene.

At first, she thought Gong Yu wanted to call Zuo Yunfeng and Mo Yun to ask her to help with their homework, but when she heard that Gong Yu was actually explaining the questions to the two of them, she couldn't help but feel surprised.

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

It seems that what Gong Yu said about bringing her textbooks to Gui City and not needing tutoring was true.

Gong Yu was actually able to read a book on her own without a teacher’s explanation?

This is simply the standard of genius!

When Liu Xiaodan thought about the fact that she had taught a talented student, her heart beat faster and she could hardly contain her excitement.

Subconsciously, she did not disturb Gong Yu's explanation, but stood quietly at the door listening, and also wanted to hear how deep Gong Yu's insights into the topic were.

Upon hearing this, Liu Xiaodan became even more excited.

Gong Yu not only knows the knowledge in the textbook very well, but can even draw inferences from one question to another and come up with opposite questions for Zuo Yunfeng and Mo Yun to do.

Moreover, Gong Yu's approach to solving the problem also surprised Liu Xiaodan.

She had never thought of such a solution to the problem.

In fact, Gong Yu only used the Olympiad mathematics that was highly praised by later generations to solve the problem.

Originally, Liu Xiaodan thought that Gong Yu would give the answer directly, but Gong Yu patiently guided the two of them step by step towards the correct solution, allowing them to think for themselves and finally come up with the answer.

Liu Xiaodan really appreciates this teaching method.

It not only increases students' enthusiasm for participation, but also allows everyone to use their brains to think, and ultimately transform knowledge into their own and be able to use it flexibly.

What made Liu Xiaodan even more unbelievable was that Gong Yu not only explained the knowledge that had already been learned, but also applied the knowledge that had not been learned since then to the current questions.

Even when Gong Yu was explaining an unfamiliar concept, Liu Xiaodan discovered that Gong Yu was explaining knowledge that would not be taught until the next semester.

Could it be that Gong Yu has already finished studying the textbooks for next semester?
