Zhang Yi, an intern who was almost fired, unexpectedly acquired a miracle medical system. Not only could he accurately find out the cause of a patient's disease, but he could also practice various medical skills repeatedly in a simulation laboratory. Zhang Yi relied on the system to save lives and heal the wounded in the hospital, starting from the emergency department and completing a series of difficult operations, gradually becoming a star doctor, and then counterattacked to become the most powerful doctor. This work is adapted from the Tomato novel When the Doctor Has a Simulated Operating Room, written by Zhe Ergen Xiangcao.
