It tells the story of Lin Ran, a security guard at a low-level hospital. He was framed and fired for preventing a medical incident and was banned from the industry. When he was desperate, he was helped by Lao Zhou to find a new job. However, on his first day at the new hospital, he accidentally traveled to the ancient "Yong'an Top 3A Medical Center" and still established himself as a guard. Faced with the chaotic order of ancient medical clinics, medical troubles, bandits, plagues and other crises, he abandoned his confusion and combined modern security thinking with ancient reality to learn first aid, set rules, and fight against evil forces. In the process of adhering to kindness and justice, he counterattacked from a down-and-out little man to a "predator" who protects medical clinics and patients, completing the story of self-salvation and growth.
