Kapitel 303: Chapter 303: Uncle Si, you won't be able to chase Weiwei like this

Duan Feihan returned from working overtime at the company and inquired with the Duan Family's butler before striding towards Duan Xingye's bedroom.

Duan Xingye hadn't locked the door, so engrossed in solving problems that he didn't even hear Duan Feihan knocking.

Duan Feihan walked in and saw Duan Xingye scratching his head over a math fill-in-the-blank question and said indifferently, "Negative square root of three."

Duan Xingye jumped in surprise and looked toward the tall and handsome man, "Fourth Uncle, when did you get here? I'm doing my homework! Negative square root of three? Oh yeah, that's right, I made a mistake just now! Fourth Uncle, you're impressive, still able to do college entrance exam problems years after finishing grad school?"

Anyone else would have long forgotten.

His Fourth Uncle gave him the answer straight away in his head without even needing scrap paper. Ah, that's the difference, so frustrating.
