Not only were other ordinary students surprised by Qin Yuchen's extraordinary memory, but even Su Qi, who also had an extraordinary memory, couldn't help but be surprised at this time.

In her first life, she didn't have such an extraordinary memory, and she knew that people who didn't have such a talent could only achieve the purpose of remembering by looking and reciting things over and over again.

But the result of this is that no matter how many times you repeat it, you will always forget the place again, and you will never be able to remember not only the knowledge points, but also the location of the knowledge points like Qin Yuchen, and you can also accurately find out which book, which page, and which line this knowledge point is in.

She knew that Qin Yuchen's position in remembering these knowledge points was definitely not deliberate, but ......

After reading it, it will naturally be remembered.

Because she is like this now, she never forgets it, but she remembers what she has seen at a glance, whether it is a long or short paragraph, or the page number and accompanying illustrations that she accidentally aimed at.

It's just that the reason why she has such an extraordinary memory is because of the experience of being reborn.

Compared to a cultivator like her who could cultivate to achieve immortality, Qin Yuchen was just a mortal.

Such a mortal has such a ability, and it is more than enough to call it a genius.

Su Qi suppressed the surprise in his heart and began to listen carefully.

If she had already read the high school math books, she would no longer need to write down the positions of the knowledge points mentioned by Qin Yuchen like other students, and then go back to review.

However, the cruel truth is that even if she has a great memory, she has not had time to read the book, so she can only write honestly.

So when Qin Yuchen's eyes inadvertently swept to Su Qi, who was in the bottom two position of the first group, he saw the little girl holding a pen with her head down, writing very seriously.

Although she lowered her head slightly, her back was very straight, and her neck was already a slender swan neck, and there was a perfect curve between her lower heads.

Because she lowered her head, her hair fell slightly, and she brushed her hair behind her ears as she wrote......

Such inadvertent actions make the already dazzling people even more distracting.

Qin Yuchen's gaze couldn't help but soften a lot.

Although Zhao Chengfeng didn't want to see Qin Yuchen, he had to admit that Qin Yuchen's teaching level was the highest among all the teachers he had ever seen, including all the teachers in the subject of mathematics.

Even if Teacher Gao compares with him, it is much worse, so aside from seeing him, Zhao Chengfeng also plans to take class seriously.

But......

It didn't take long for him to be serious before he found out that Teacher Qin was deserting?

What are you doing deserting?

Zhao Chengfeng's eyes widened, and he raised his hand and stood up......

"Teacher Qin, I have read books on advanced mathematics, and the last question about this problem, is it feasible to use the knowledge of calculus to solve it?"

Zhao Chengfeng stood up too suddenly, and the question was too sudden, and a different teacher, especially the teacher who was deserting, might not be able to react for a while, but who is Teacher Qin?

He just has the ability to desert and at the same time, he perfectly answered Zhao Chengfeng's sudden question.

"It can indeed be solved with the knowledge of calculus, which specifically involves the first-order differentiation, that is, the differentiation corresponding to the first derivative of the function." Qin Yuchen took the chalk and turned around and wrote on the blackboard.
