Yun Heng, a master's graduate from Zhongzhou University of Traditional Chinese Medicine, offends the head of a department at a top-tier hospital and faces rejection everywhere in his job search, leaving him with no choice but to take a position at a grassroots community hospital. Unexpectedly, he awakens a medical simulation space that allows him to simulate diagnoses and treatments, correct mistakes, and advance his skills. With the system's support and his solid medical expertise, he starts as an overlooked young practitioner of traditional Chinese medicine, successfully treating long-standing illnesses and medical emergencies one after another. As he earns patients' gratitude and trust, he humiliates the colleagues who once ostracized him and attracts the attention of experts from provincial hospitals, who come personally to recruit him. Thus begins his remarkable rise as a master of traditional Chinese medicine from the grassroots.
