Lin Yi, a graduate majoring in traditional Chinese medicine, encountered obstacles in his job search. He accidentally activated the disease entry system and could directly see the patient's lesions, causes and symptomatic treatments. He combined his ancestral traditional Chinese medicine skills to save critically ill patients one after another in the hospital: he identified the difficult-to-diagnose Dai Yang syndrome, used ancient acupuncture to stabilize the serious illness, and uncovered the doctor's trap and the nanny's poisoning conspiracy. Being ostracized by his peers and the differences in the concepts of Chinese and Western medicine kept coming, Lin Yi stuck to his original intention of practicing medicine and used the secret technique of Tianliang acupuncture to overcome post-operative high fever, intestinal paralysis and other diseases that were difficult to treat with Western medicine. He was recognized by patients and seniors for his strength, and turned from a down-and-out intern into a backbone of the department, inheriting the treasures of traditional Chinese medicine through the combination of traditional Chinese and Western medicine.
