The protagonist, Chen Yang, was born in a remote mountain village and is the heir to a declining family of shamans and healers. His family was once renowned for its healing arts, but a mysterious calamity gradually brought it to ruin. Now, only Chen Yang and his elderly grandfather remain to depend on each other. At school, Chen Yang is often bullied by wealthy students like Zhao Yu because he comes from a poor background and keeps a low profile. During a school health check, a teacher suddenly falls gravely ill and loses consciousness. The school doctor is helpless. Drawing on the basic knowledge of healing passed down through his family, Chen Yang attempts to help. After a few acupuncture needles, the teacher slowly comes around. Zhao Yu and the others are jealous and resentful, and make life even harder for him.
Not long afterward, Chen Yang's grandfather becomes seriously ill and bedridden, leaving Chen Yang distraught. While sorting through old family belongings, he accidentally triggers a mechanism and finds a mysterious jade pendant. A vast body of knowledge floods into his mind: the long-lost, complete inheritance of his family's healing arts, including unique acupuncture techniques, herbal remedies, and methods for communicating between yin and yang. Chen Yang begins studying day and night, trying out his newly learned techniques to treat his grandfather. Gradually, his grandfather's condition begins to improve.
