It was some thirty or so years after Siu Yeun San and Mo Yung Bok first snuck into the Shaolin Temple in DEMIGODS & SEMIDEVILS that they were finally (after the Heroes' Conference at Shaolin) confronted by the Janitor Monk, who subdued them and ended their decades-long feud. Siu Yeun San and Mo Yung Bok were such great martial artists that it's not hard to imagine them being able to stealth their way around everybody at Shaolin for thirty years . . . *except* for the Janitor Monk. Given the Janitor Monk's nearly god-like abilities, it seems unlikely that he didn't know they were there. If he did know, however, why did he wait so long before acting against them?
