Fu xia shen qiang chu san hai (1966)

Lanky Fellow has a typical cynical SW like way to earn his living. He observes valuable transports of money or gold, but when they are robbed he doesn't intervene, but follows the robbers and then brings the loot back to collect the insurance. When his "job" brings him in conflict with the notorious outlaw Gus Kenneback, he has personal reasons to protect the money as Kenneback was once responsible for the death of Lanky's brother.
