Bruce Tuan 7-Promise (1979)

Flamboyant kung-fu stylings and arterial blood-spray are let loose when the fantastic jade sword, a weapon that can kill a man without even touching him, is lost by the very person who was supposed to be keeping it safe. A search quickly reveals a conspiracy involving rogue Shaolin monks, powerful ruling families, and ever mysterious deadly Green Dragon Gang. When the dagger is used in a murder, and an unknown man is found barely alive in a box at the bottom of a river, the questions get more numerous, and trust is something that comes and goes quickly as the wind.
