The protagonist Lu Chen is a private detective. Disappearances occur frequently in the city, but in fact, fairies and demons secretly prey on humans. He joined the secret organization "Vigil Division" and relied on reasoning to track the strongholds of the three clans. It was discovered that he wanted to use the city's spiritual veins to refine medicine, and combined with the superpowers to sneak into the altar, destroy the ceremony and seal the spiritual vein nodes, temporarily ensuring the safety of the city.
