During the Republic of China, martial arts masters were scattered throughout the streets and alleys of Longcheng.
Rumors of the secret treasure Linglong Picture gradually brought them together and attracted a large number of outsiders, including foreigners. Everyone wants to get Linglong Picture. Desire permeates the city. What followed was a series of criminal cases and martial arts battles.

They joined forces with the highly skilled police captain to clear away the grievances of their master, but failed to catch the real murderer... Since then, masters of the martial arts have frequently appeared among the people.
