During the Republican era, martial arts masters were scattered throughout the streets and alleys of Longcheng.
Rumors of the Linglong Map, a hidden treasure, gradually drew them together and attracted a large number of outsiders, including foreigners. Everyone wanted the map. Desire spread throughout the city, bringing with it one crime after another and one martial arts clash after another.
The sole descendant of a family wiped out in an unsolved massacre decades earlier was murdered just as they revealed the treasure’s whereabouts. The first female forensic investigator to return from studying abroad, fluent in Cantonese, was assigned to solve the case. Teaming up with a highly skilled police captain, she sought to clear her master’s name, but they failed to catch the real killer... From then on, martial arts masters began appearing in the streets and among ordinary people.
With factions converging on the police department, they had no choice but to join forces with a fortune-teller skilled in the arts of divination and geomancy, a musician who could control people with her playing, an eccentric old man from the Tai Chi school, and a mischievous old gentleman who knew how to enjoy life. In this turbulent martial world, they must protect what matters most to them!
