During her lifetime, she was the black ledger of Lord Yama, recording thousands of wronged souls and sins. After her death, her soul was shattered into madness, leaving only a ray of obsession. When he, the demoted surviving son of the Yin Dynasty, approached her as a spiritual medium, but he didn't know that she was the ghost of his mother; when Bai Gu Niang taught her to write, Liu Qingya lured her into the game, and Ah Tang's talismans actually rewritten the laws of the Yin Dynasty... Who dared to touch her? She is not a ghost, not a weapon, she is the torn 'justice' itself. Now, the ledger has awakened, and the underworld is about to fall.
