The weak marquis's daughter Eleanor is poisoned by her husband Victor and his mistress, stripped of her family fortune, and even implicated in her grandfather's brutal death. After being cornered with no way left to retreat, Eleanor casts off the fear forged by her trauma and turns to alchemy, weaving terrifying hallucinations to launch her counter-kill. Through step-by-step schemes, she burdens the villains with a million blood debts, ruins their reputations, and turns them on each other. In the end, she is crowned Grand Duchess of the Empire, completing an iron-blooded comeback.
