Catalog of the Netherworld

Every ghost building is a living map, and every ghost master marks his own death coordinates. What Feifei and Dudu have to do is to find all the puzzle pieces on the map and piece together a way to survive. Yong'an Building, abandoned hospital, last subway, midnight amusement park... 49 Ghost maps, 49 rules, every time you step into it is a game of life and death. Feifei can hear the footsteps of ghosts, can hold his breath and cheat death, and can break the rules and reassemble them. The price is that the right eye turns red, the black line spreads on the right hand, and the sunny smile is swallowed up by the evil bird of prey day by day. Dudu has no abilities at all. He only has a ruffian spirit, a Tianjin accent, and an almost animal-like intuition - and the hand that never lets go of Feifei's clothes. The mastermind behind the scenes, "Wanxiang", whispered in the abyss: Become me and you will live forever. Feifei looked at the black line on his right hand that was almost reaching his heart and smiled. "Eternal life? No need. It's enough for him to live."
