Li Chongbai sat on the elevator with a solemn face, his eyes flashing with anxiety.
"Pei Yu, go directly to the eighth floor," he instructed.
His apprentice, Pei Yu, who followed behind into the elevator, immediately pressed "8" and then turned back to look at Li Chongbai.
"Teacher, how did you come up with that ten-page prescription last night? I've read the treatment method written on it, it's even better than the treatment plan you proposed yesterday afternoon," Pei Yu said.
Li Chongbai's eyes flickered with struggle. He opened his mouth to speak but hesitated.

The eighth floor arrived quickly, and the elevator doors opened instantly.
Li Chongbai stepped out first.
A puzzled Pei Yu followed behind, constantly asking, "Teacher, what's wrong with this prescription? I can't see any problems with it."
