Heavy snow in Xiangnan, the birthday of the City God. A mysterious teenager, Wang Jin, holding a red oiled-paper umbrella, walked down Baimei Mountain, and after talking with the City God, stepped into the mortal world. Meanwhile, Xinhua Residential Area suffered consecutive bizarre murders, with the victims' bones and blood completely drained, leaving the police helpless. Li Shunsheng, a trainee detective captain who had witnessed Wang Jin's supernatural abilities at the City God Temple, decided to let him investigate the scene. Wang Jin used the victims' fresh blood to summon back their wandering souls, learning that the killer turned out to be a cultivator zombie; he then had Li Shunsheng hold an umbrella for a female ghost, tracing the true culprit following the wronged souls. When the Taoist talisman formation from Longhu Mountain sealing the zombie appeared in the dilapidated building, Wang Jin discovered that the prey had already escaped. He instantly leaped up the building, transforming into a long rainbow as he chased into the snowy night.
