Xu Zhiwei is a graduate of modern clinical medicine. When he woke up, he became the most unpopular Xu Changzai in Dayin's harem. What's worse is that as soon as she opened her eyes, she was taken to Hanzhang Hall for questioning. The imperial concubine was poisoned, the queen urged her to die, and the queen mother forced her to confess. The whole palace was waiting to see how a rootless concubine would die with dignity.
Xu Zhiwei has no system or golden fingers, only observation, judgment and first aid instincts trained in modern medicine. She relied on drug detection, syndrome differentiation, and reasoning step by step to protect herself. She also relied on ancient books and modern understanding to support each other. She struggled to gain a foothold among the Imperial Hospital, the harem, and the court. She gradually changed from a "disposable" chess piece to a person that no one dared to touch easily.
As for the young emperor Xiao Heng, he only used her as a tool to break the situation at first, but through life and death and temptations, he saw that she would not flatter, shrink, or despise human life. The palace is like a prison, and the phoenix is like a blade. She enters the situation with a medical heart and breaks it with a clear mind. Between the intrigue and pulling, she slowly moves towards the person who is equally calm but is willing to make an exception for her after all.
