Synopsis：She once apprenticed under a genius physician and was the beloved daughter of the Prime Minister, marrying into the royal family for love. Yet her husband was ruthless—on her birthday he seized her family’s estate and allowed his lover to torment her to death. Reborn in the flames, she awakens as the Regent’s concubine. This time, she vows to make every debt paid in blood: helping the Regent seize the throne, deposing the Crown Prince, crushing the vicious mistress, and transforming from a timid victim into a fearless warrior who controls her own destiny.
