Emergency doctor Shen Hengzhi traveled through time and became the criminal daughter of Beishuo Huanyi Bureau, and was in a desperate situation. With her cutting-edge modern medical knowledge, she bucked the trend in the palace where the epidemic was raging: she saved the dying empress dowager through isolation and infection control, and was awarded the title of "Jin Cai Nv"; she opened a free clinic for palace residents, used nutrition to recuperate the emperor, and won the emperor's trust. She is far more than just a medical practitioner - using auditing techniques, she peels off old accounts and uncovers the shocking story of embezzlement of millions of military dollars by the queen's relatives; when her opponent counterattacks with witchcraft, she actually demonstrates forensic evidence in court, overturning a century-old family in the court. From a sinful girl to a queen, she established the Royal Female Medical College to control the medical affairs of the inner court. When the emperor was chronically poisoned and his life was hanging by a thread, she used accurate toxicological analysis to find out the real culprit. In the end, she was the mother of the world, supervising the country's governance, and covering the nine palaces and the common people of the world with the fragrance of modern civilization.
