When Internet writer Qiu Xiaobei opened the door of Room 304 of Qinghe Apartment, he could no longer escape this cursed place shrouded in blood mist. The dark red blood mist swallows the light, and missions with letters of blood come one after another. The reflection of the ghost in the power distribution room at midnight, the resentful woman in red in the deserted village of the ancient house, and the countdown to death in the closed space. Every mission is a game of life and death.
Rules are the only life-saving talisman, death certificates are the last resort, and cursed objects hide both ways of survival and murderous intentions. In the abyss of absolute fear, human greed and betrayal are more deadly than evil spirits. The improvised tenant alliance oscillates between suspicion and trust.
