Lu Xuan transmigrates into a parallel world and becomes the owner of an unknown horror house, only to discover that his NPC employees are all top-tier demon kings: Hua Guo Jinqi, Huaxia Corpse King, and Vampire Dracula. Several members of the Special Forces Team from Longguo, accidentally chased by a skeletal demon, stumble upon this mysterious horror house and realize its NPCs are actually powerful demon kings.
