The Deadly Silver Spear(1977)

Silver Spear (Jimmy Wang Yu) is a deadly Kung Fu bounty hunter who has been hired to kill three martial arts experts. When the white-haired super-warrior known as The Old Hermit hears about this, he sends some of his own men to put a stop to it. But these newcomers are no match for the mighty bounty hunter, so The Old Hermit sends more, and more, and more, succeeding only in whipping up the raging martial arts maelstrom that is Silver Spear.
