Anyone find it weird that Iwao was not even in the same league as Lan Di in his martial arts?
Iwao trained with and was presumably on par with Lan Di's father although admittedly Sunming Zhao was killed before he became a "legendary martial arts master".
Still why did Iwao perform so embarrassingly against Lan Di? I don't think it was a matter of age.. Iwao was only 46. My guess is that Lan Di was using the forbidden "Tiger Swallow" style that was banned because it was too dangerous and deadly?
