The Janitor Monk was the single most powerful character to appear in Jin Yong's stories. The Janitor Monk took the identity of a Shaolin monk, but nobody knows if the incredible abilities he exhibited were Shaolin martial arts. Some speculate that his skills are Shaolin skills taken to the Nth Degree. Others believe he might be a Siu Yiu Sect member (perhaps even the teacher of Mo Ngai Tze, etc.). Yet others believe that what he used was not martial arts at all, but divine power.
So what do you think?
