Su Wan is trapped in an infinite time loop of the last 12 hours before her birthday. Every midnight is the moment of her death. The scheming of family members, the betrayal of close friends, and the disguise of a lover tear away their gentle masks in cycle after cycle. Three hundred and seventy-two deaths, three hundred and seventy-two struggles, she thought that as long as she broke the reincarnation dungeon, she could escape the abyss. But when she broke free from the 12-hour time cage, she suddenly realized that all the reincarnations, sufferings, and encounters were just a game of chess set up by a high-dimensional arbiter across ten thousand generations. She and Lu Yan are twin chess pieces chosen by the gods; all past sacrifices, redemptions, and loves are entirely written in destiny.
