The difficulty of Zhang Ye's questions!

Sunday.

The next morning.

The day before the deadline for the submission of the exam questions, everyone woke up and ate the breakfast delivered to them. Every team's question setters were called to a meeting by their respective team chiefs to begin another day of work, to compile and summarize everyone's questions, then analyze and discuss it as a group.

Mathematics team.

"Dean Pan."

"Oh, you're here?"

"Everyone has arrived."

"Uh, Teacher Zhang is not here yet."

"You haven't seen him since yesterday?"

"That's right, I did not see Professor Zhang since the night before yesterday. I think he stayed in his dorm the entire time, then I heard he went to get more information and past exams."

"The deadline's tomorrow, so we have to finish the rough draft of the Mathematics exam today, or else it'll be too late. Get someone to call for Professor Zhang."

"Alright, I'll go."

Right at this moment, Zhang Ye walked into the office from outside.
