v2 Chapter 348： Sieve (1/2)

If it is proved, then everything is easy to say, but if it can't be proved, then Qin Luo's reputation will be completely cold, and even a high-level infamy will be on the back.

So lofty? Seeking a dead end?

Hearing what Ye Father said, Ye Liang nodded in agreement.

This guy Qin Luo is doing it himself.

Qin Luo didn't hear the ridicule of Ye family father and son, but even if he heard it, Qin Luo would only smile.

As a schoolmaster with a system, he really couldn't see Ye family father and son in his eyes.

Even after Ye Liang made a wonderful report on topological functions, the same was true.

Qin Luo writes very slowly, writing every word and word carefully, but as time goes by, there are more and more calculations on the whiteboard.

”1. If D cannot be adjacent to ABC at the same time, the number of colors does not increase, if D cannot be adjacent to C, then DC uses one color...”

”2. If D is adjacent to ABC at the same time, on the plane, then D must be in the center or the periphery of the adjacent graph of ABC...”

”3...”

Five minutes, ten minutes, half an hour...

As time passed, the slowly noisy discussion disappeared, the slowly hearty voice disappeared, and in the end there was no breathing even, and the whole lecture hall fell into dead silence.

”Did you bring paper and pen?” When Qin Luo's formula occupies more than half of the whiteboard, Wang Xuecai turned to look at the assistant teacher behind him.

The teaching assistant is a graduate student, about twenty-four or five years old. After he heard Wang Xuecai's words, he always took out the paper and pen with the briefcase and handed it to Wang Xuecai.

”Give me a copy too.” Song Baoguo said suddenly.

”And me.” Zhou Haizhong was not to be outdone in the next second.

The assistant twitched his mouth and silently emptied his briefcase.

”Thank you.”
