Before wiping the blackboard for the fourth time, Chu Long seriously studied the faces in the Lecture Hall.
He was certain that no one understood anything anymore.
But only a very small number of people left. Most stayed, perhaps out of politeness, perhaps because they had nowhere else to go, or perhaps because they wanted to stay and take pictures.
Chu Long continued writing with his scalp tingling, his hand moving as fast as Jorge's, because Song He's speech through the earpiece was also flying along. If he paused even slightly, he would fall behind.
An hour passed.

Chu Long's throat felt scorched, and his entire body was drenched in sweat. He wrote and spoke at the same time:
"From this, we obtain a smooth manifold of dimension 2m less than K-1. Therefore, Equation 8-19 satisfies the Song He Zero Measure Set..."
"K2 and K3 can be covered by infinitely many Song He coordinate charts. Therefore, there is an injective immersion from Ni into space G..."
"Take any positive smooth exhaustion function on L. By Definition 9-7, we obtain..."
"Thus, the Song He Manifold conjecture holds!"
After Chu Long finished speaking, he suddenly froze himself, as if he had been struck by a petrification spell. He stood rigidly in front of the blackboard, completely motionless!
The audience in the Lecture Hall was dozing off. Some people vaguely heard that final sentence and jolted awake, their heart rates beginning to soar!
For several seconds, the entire Lecture Hall fell into an eerie silence.
The silence startled awake some audience members who had been on the verge of falling asleep. Like students who had been dozing in class and suddenly realized the teacher had stopped speaking, they looked around in bewilderment, not understanding
