Rebel Princess: The Divine Doctor Outcast帝凰之神医弃妃

A modern military doctor accidentally time-travelled during her mission. She became Feng Qingchen, the daughter of the late general of the ancient Tanglin Kingdom, and found herself in a bandit's den.  With her life endangered, Feng Qingchen grabbed a scalpel from the medical system and killed a few bandits. When she left the bandit's den and was about to wander the world free and unfettered, Wanyin, the servant girl of the owner of her body suddenly appeared to stall her. Feng Qingchen's fiancé, Prince Luo, rushed over with his army just to find Feng Qingchen in dishevelled clothes. Doubting her chastity, he ordered her to commit suicide.
