Tomb of the Concubine: I Am a Detective in a Cursed World

(No CP + suspense reasoning + micro-horror, the heroine's IQ is online throughout the whole process, and the reasoning to break the curse is full of excitement!) Traveling through a strange world full of curses, I was caught by the most vicious curse in the world, and the evil spirit kept calling me mother! Once I became the "mother of curses" that everyone avoided, others would die if they encountered the curse, but I relied on hard-core reasoning skills to survive: A murder case in a secret room in a deserted village, I uncovered the man-made conspiracy under the illusion of a curse; There were suspicions about a murder caused by a curse in the air on campus, and I deduced logic to calm the panic of the whole school; A series of curses have been placed on the ancient house. I uncovered the rules of the curse and killed the mastermind behind it! No system, no CP, rely solely on IQ to break the situation, and use the wisdom of a detective to tear apart all the evil spirits! But the more I unravel the curse, the more frightened I become. This curse that calls me my mother actually hides the ultimate secret of the entire cursed world—— And I have been cursing the most critical piece on the chessboard from the very beginning!
