The Knife of Devil's Roaring and Soul Missing (1976)

The movie is structured much like a murder mystery, albeit one that gives the viewer a fight scene every couple of minutes. There’s a murderer who goes by the moniker Devil Swordsman gallivanting around the countryside in an outfit that looks like a ninja cloak by way of a KKK robe who’s killing all of the major kung fu masters and clan leaders with a single swipe to the face. One of his first victims is the head of the White Dragon tribe, whose son, Shan, is played by Dorian Tan Tao-Liang. Shan naturally assumes the role of detective in order to avenge his father, since that’s what people do in these movies.
