Modern forensic doctor Su Wan dies suddenly on the autopsy table and transmigrates into the body of the Prince of Jing’s bride, brought into the Southern Liang royal family to bring her sickly husband good fortune. She opens her eyes straight into a deathtrap: the original owner has been accused of having an affair with a guard and is bound hand and foot, kneeling in a torrential downpour, with three options laid before her: a white silk noose, poisoned wine, or a dagger. The violent prince sits beneath the corridor roof and sneers, “Choose how you want to die.” When a twenty-first-century medical System collides with the bloodline of an ancient clan of Gu poison masters, a tale of love and political intrigue spanning three kingdoms unfolds, as she transforms from a stand-in bride into the true mistress of the prince’s household.
