Son of the Swordsman (1970)

Synopsis

When Master Leung tries to rob Wong I-Hsia of a precious cargo he must protect, Wong I-Hsia fights him off with the iron palm and makes his escape. Too old and weak to continue his mission, Wong I-Hsia entrusts the cargo to his eldest son Wan Fu, who wastes no time in proving his fighting skills as he slays 50 of Master Leung's men fighting off a forest ambush.
