장 185: I'll Learn For a Bit

He didn't think that after feigning as a master teacher for so long, such that everyone had already believed him to be real... that he would stumble on the lack of trivial knowledge.

If he knew that there aren't any poison masters in Tianxuan Kingdom, he would have never said such words!
