Is this question in Chapter 317 difficult?

The third teaching building.

In the large lecture theater on the second floor.

Chen Yu sat in the corner and listened carefully to Professor Zhong Feiyu's differential geometry class on the podium.

Although he has now completed the study of the system tasks, received the reward, and accepted new tasks, Chen Yu will still come to every class taught by Professor Zhong Feiyu.

On the one hand, Chen Yu is very clear that he can never be considered to have finished the course of differential geometry. The differential geometry course he has taken now can only be regarded as the beginning of differential geometry. Differential geometry is a very big topic nowadays. In the field of research, there is a lot of profound knowledge in this field that he has not yet learned. Even in terms of textbooks, he has only completed part of the study of the large field of differential geometry, and there is still a large part to follow. It's something he hasn't finished lea
