The protagonist, Sikong Yue, is a reclusive medical king with peerless medical skills. He has lived in seclusion in the mountains for many years. However, due to an accident, he was forced to leave the mountain and was forcibly invited by local dignitaries to treat illnesses. In order to keep him by their side and serve only themselves, the powerful men used coercion and inducement, and even ridiculed him as "just a medical beast. It is your honor to be reused by me." Sikong Yue became angry and broke up, saying "I am a doctor, not an animal. I only save good people and do not serve evil masters." With his peerless medical skills, he cured the people while exposing the evil deeds of the powerful. He finally cleared up the local evil forces and returned to the mountains and forests. However, he became a reclusive medical king that everyone respected. Some people paid a lot of money to seek medical treatment, but he only saved kind-hearted people.
