The Divine Doctor's Spoiled Little Demon Consort

A gifted modern doctor wakes up as the timid, useless third legitimate daughter of a general’s household, branded with the curse of having been born to kill her mother. Scheming concubines and bullying sisters? She’ll serve them all a dose of poison! Her enemies from two lifetimes covet her future husband. Take him, then! She has her eye on that seemingly frail, easy-to-handle pushover! So much for the pushover she was promised. What’s with all those mysterious identities? She can’t get him under her thumb and instead ends up completely at his mercy. She wants a refund! He says, “The goods have been sold, and I’ll throw in the favor of the whole realm. Still want to return them?” Since he’s so sincere, she might as well make him her backer and forge a path to dominate the world, wielding medicine as her ultimate weapon!
