Lin Wan is the most diligent resident doctor in the emergency department of a city hospital. After a night shift, her consciousness can receive "emergency orders" from another world. On one side are the performance appraisals and difficult and urgent diseases of modern hospitals; on the other side are the plagues, difficult childbirths, quackery and destiny of the Jing Dynasty. She used evidence-based medicine to establish an "evening hall" and a life-saving network in ancient times, and she also used ancient cases to feed back the modern operating table.
The system can report numbers, be venomous, and make people angry, but it never makes a decision for her; saving people's lives is a waste, making wrong diagnoses is deducting reputation, and every cheating of hers is marked with a price.
When she was pushed by sentient beings from both worlds to the Taiyuan Hospital and the rules level, she realized that this system, the previous host, and the "demon doctor" who was burned to death thirty years ago were hiding the same plan to use the will of all sentient beings as a sacrifice.
This time, she wants everyone to save themselves.
