The Untamed Doctor

An explosion at the base kills a modern special agent and military doctor, and she wakes as Xi Yang, the most spoiled and worst behaved noblewoman of the Xuan Zhou dynasty. She arrives already dosed with Fiery Flame Poison, an aphrodisiac she cannot ride out alone, and the man she ends up in bed with is Zongzheng Yu, the regent prince nobody in the dynasty is willing to cross. She returns to the Xi household as the legitimate daughter and the story goes around that she lost her virtue before marriage. The mistress of the house bullies her without bothering about facts. The second branch of the family quietly hires men to kill her. The third branch works on poisoning her. The girl whose body she is wearing would have had no defence against any of it, but she is loud, quick and willing to fight, and she wins Zongzheng Yu over. As his consort she has a rank the Xi family cannot touch, and she intends to use it to avenge the dead Xi Yang and put her own branch of the family back where it belongs.
