He Zhizhou, once a surgical genius who stood at the pinnacle of the world, conceals his identity and retreats into an easygoing life in the emergency department, slacking off whenever he can. He sleeps and plays games at work, writes sloppy medical records, and is regarded by the entire department as a useless employee who got his position through connections. The department director gives him a deadline to get fired. Yet whenever critically ill patients teeter on the brink of death, he effortlessly brings them back to life. He only wants to coast through his days, but the entire hospital ends up begging him to save lives!
