Chapitre 621: I Solved It

The chalk on the blackboard stopped moving.

The explanation from Lu Zhou also stopped.

Everyone in the audience was stunned.

Lu Zhou's hands hadn't stopped writing for the past hour, and now that he suddenly stopped, everyone felt a little uncomfortable.

However, everyone knew that when someone was in an unusual environment, they were bound to perform worse than usual. Some people even witnessed old professors dozing off while reporting. Also, this was a major mathematical proposition. Not only did it test the reporter's mathematics level and articulation ability, but it also tested the reporter's mental endurance.

Everyone waited in silence.

However…

10 seconds passed.

5 minutes passed.

Lu Zhou still stood still on stage. He stared at the blackboard like he was thinking about something.

Seeing how he didn't react for a long time, the audience began to worry.

Why hasn't he moved yet?
