Two great mountains stand side by side: the Maoshan Sect, which uses talismans to drive out evil, enters the world to save lives, and practices nimble Taoist arts; and Mount Longhu, which uses thunder techniques to suppress demons, upholds the nation and protects the Dao, and practices upright arts. Their philosophies differ, and they compete with each other.
· Spiritual qi revival, with demons and evil spirits running rampant: In a modern urban setting, monsters and spirits quietly take root in human desires, giving rise to a "hidden world."
· The Supernatural Affairs Bureau: A covert government agency established to manage supernatural incidents and maintain a delicate balance between the two sects.
