February arrived in the blink of an eye.
After a month, He Yujie, Xia Yuanli, and Xu Qitai had quickly adapted to life at Cambridge University.

Looking at the seven or eight little pulleys twisting and winding across the simple blackboard, the three of them felt their heads swell. They realized they were frogs at the bottom of a well.
Wasn't Newtonian mechanics just F=ma? How had it become such an advanced body of knowledge the moment it passed through Teacher Li's hands?

He Yujie's eyes gleamed. "Big Brother Li is a hundred times better than Instructor Davis!"
Xu Qitai sighed even more emotionally. "Big Brother Li
