Turns out, right from the start, the man in black had used several of Shaolin's unique skills in the duel, which included the "Prajna Palm" and the "Demon Flail" techniques. These were the techniques that Ye Weiming had mentioned earlier, used by the villain who had attacked Xuan Ku twice before.
The magnitude of the opponent's martial arts skills is undeniably sufficient for him to severely injure Xuan Ku in an ambush and retreat unscathed.
Moreover, his techniques perfectly matched Ye Weiming's previous description of the "villain."
With this combination of evidence, Xiao Feng had no reason not to suspect the man before him to be his sworn enemy, a feud that would only be resolved upon one's death!
Knowing all the underlying reasons, Ye Weiming did not attempt to clarify the misunderstanding.
Xiao Feng had mistaken this man for Xiao Yuanshan, the culprit who ambushed Xuan Ku, but Ye Weiming had already deduced his real identity.
