The Reborn Emperor and Empress

She is one of the top 10 all-around doctors in country A who is both Chinese and Western medicine. On her way to work one day, in order to save a family of three, she resolutely crashed into a car and died on the spot. However, she time-traveled into the body of Miss Ninth, a concubine of an imaginary dynasty's Prime Minister's Palace. She was not favored? Being bullied? Being used as a pawn by the prime minister's father and betrothed to the prince who was once victorious and powerful in the world but was unexpectedly lame? And how she worked step by step to become a medical goddess and empress who was passed down through the ages.
