Chapitre 424: Instructor Xu's Self-Reflection (1)

However, the more this was the case, the more Instructor Xu was afraid.

Normally speaking, logical errors would be carried out from the beginning to the end. Then wouldn't he be finished?

But that was not right. If he had made such a big mistake, shouldn't Professor Chi have pointed it out immediately? Why would he call back now?

Instructor Xu's mind could not help but be filled with a string of question marks. In the end, it suddenly became clear.

He seemed to have understood!

It wasn't that the professor didn't notice his mistake, but he was waiting for him to react. That was why he didn't point it out immediately. Who knew that he would be so stupid that he still didn't realize which step he did wrong. Then, the professor waited for a long time after the call ended, but he didn't get a reply. He couldn't take it anymore and called again.

However!

Even now, he still didn't know where he had gone wrong.
