Medical student Yang Ming was accidentally bound to the "Medical Inheritance System". He thought it was just to assist in diagnosing diseases, but he discovered that the system could continuously upgrade and unlock new abilities as he treated patients and solved difficult and complicated diseases. He started from his own small clinic that was on the verge of bankruptcy. With his upgradable system, he cured celebrities' strange diseases and resolved hidden diseases of high-ranking officials, and became famous all over the world. What followed was not only honors and followers, but also suppression by medical giants and the prying eyes of ancient medical forces. When the system was unlocked to the highest authority, he suddenly discovered that behind modern society, there was a medical battlefield related to the fate of the country and the survival of mankind.
