When Lin Daiyu steps into the Rongguo Mansion, everyone is smiling.
Only she sees a faceless female ghost clinging to Grandmother Jia's back.
Modern girl Lin Zhao dies unexpectedly and wakes up as Lin Daiyu, just arrived at the Jia family estate. She also awakens a System that investigates and settles wrongful-death cases in the underworld. The System tells her she has only ninety days left to live, and that the Jia and Ning mansions' century of wealth was bought with countless women's lives.
A maid in a dry well, infant bones beneath a Buddhist shrine, a paper bride sent out from the Ningguo Mansion in the dead of night... Every injustice she clears restores some of her lifespan and unlocks a supernatural ability of the underworld.
Everyone thinks Miss Lin is sickly and frail, dependent on others for shelter. Little do they know that by day she writes poetry, and by night she interrogates ghosts. She changes the fates of the Twelve Beauties while bringing the Jia family's century-old crimes before the court.
Until the Prince Jing, surrounded by baleful energy and feared by every ghost, shields her behind him. "The living are mine to interrogate, and the evil spirits are yours to judge. If the laws of heaven won't give you justice, then I'll rewrite them with you."
