At this time, a knock sounded on the office door. Everyone turned to look and found An Xiyu standing there.
"Mr. Ye, I'm sorry to disturb you, I am Professor Guo's assistant. Professor Guo sent me here. I have something I'd like to discuss with Xiang Beifei. May I borrow Xiang Beifei for a moment?" An Xiyu was very polite to Ye Changfeng.
"Sure, Xiang Beifei, you go ahead." Ye Changfeng recognized An Xiyu, a student whom Professor Guo thought highly of; he was aware of that.
Xiang Beifei left the office and followed An Xiyu outside, where they both stood in the corridor.
"What's the matter?" Xiang Beifei asked.
"You are the class representative for the Introduction to Defense of Jiuzhou course this year." An Xiyu said.
"Oh right, seems like that's the case."
