In 2025, Building No. 9 Of the "Wanghailou" community in Binhai City was named the "Soul-locking Building". In the past ten years, 13 bizarre deaths occurred. The deceased were all residents of Room 302. The circumstances of death were exactly the same as the description of the "Soul-locking Curse" in a book "Secret Records of Forbidden Arts" during the Republic of China - the pupils were dark and unfocused, and a bloody curse mark appeared on the chest. Before their deaths, they all claimed to "see a woman wearing a cheongsam." The official classified the case as a "serial copycat murder", but residents of the community firmly believe that buried under the foundation of Building No. 9 Is the skeleton of Su Yutang, a popular actress in the Republic of China. She was betrayed by her lover and died tragically in a pig cage.
• Curse puzzle: Is it really a resentful spirit seeking life, or is someone using the legend to kill people serially? The order of death and the details of the curse seals of each deceased are highly consistent with the "Secret Records of Forbidden Arts". The murderer (or the resentful spirit) seems to be completing some kind of "ritual";
• Psychological thriller: Room 302 will amplify the residents' sense of guilt and make them fall into a "guilt illusion" - the betrayer sees the person who has been let down, the abuser relives the scene of violence, and ultimately self-destructs in fear;
• Rule-based horror: When staying in Room 302, you need to abide by three "survival rules" (① do not open the closet after 11 o'clock at night, ② do not pick up red embroidered shoes in the corridor, ③ do not respond to the singing in the mirror), and those who violate it will have trouble within 48 hours;
• Double reversal: On the surface, it is the revenge of the vengeful spirit, but in fact it hides a family grudge that spans three generations. The "soul-locking curse" is a man-made killing method, and the legend of the vengeful spirit is a smoke bomb to cover up the real murderer.
Very interesting, rich suspenseful horror novel
