บท 89: Chapter 75 Boring Professors (First add one more update for monthly pass!)_2

It was rather inexplicable. Originally, Qian Yuhai and Lu Changzheng were quite unhappy about Qiao Ze having blacklisted their numbers yesterday.

But after hearing the exchange Qiao Ze just had with Zhang Hongcai, they suddenly felt that they couldn't entirely blame the kid...

Especially that line, "I guess your Chinese scores were never any good," almost caused Qian Yuhai to suffer an internal injury.

He really almost laughed out loud.

But this clearly wasn't the right occasion, so he had to hold it in.

What he didn't expect was, Qiao Ze suddenly looked at him and added, "I've seen Professor Qian."

Qian Yuhai asked in surprise, "Oh? You've seen me? When?"

"I've watched your 'Group Theory' series of open course videos on the internet," Qiao Ze replied.

Qian Yuhai suddenly realized...

Those were a series of videos that a student had asked permission to record and edit during his lectures years ago, and they had been posted online.
