Modern screenwriter Su Jinyao transmigrates into the body of the legitimate daughter of a marquis's household—only to be framed by her stepmother and stepsister right from the start, nearly drowned alive under clan law. Armed with forensic knowledge and mind-reading abilities, she analyzes herbal residue, reclaims her dowry, dismantles poison plots, and exposes a top-secret military conspiracy—striking back at every turn, tearing open the dark secrets festering in both the marquis's inner court and the imperial court.
