In Hong Kong in 1983, there was an undercurrent surging under the neon lights. Chen An, a small antique shop owner who looks cynical and speaks eccentrically, is actually a descendant of a strange family who can "change destiny by borrowing luck." When his family set up a trap to seize the ancestral compass and pushed him into the death trap of Kowloon Walled City, Chen An relied on his poisonous mouth and his luck skills to fight his way through the gray area of Hong Kong's comprehensive world. From the unsolved cases at the Yau Ma Tei Police Station to the internal purges of Hongmen, from the duel between thousands of people on the gambling boat to the occult battle at the Peak of Victoria Peak, this feminine man uses the gentlest tone to play the most ruthless game. When the family discovers that what they have released is not an abandoned son, but Yama who has accepted his fate, the rules of the world of Hong Kong Island need to be rewritten.
