Lin Yu, an emergency doctor at a modern small hospital, accidentally activated the "god-level medical system" and gained instant mastery of all medical knowledge, ability upgrades, and access to advanced medical equipment blueprints and other incredible functions. In the medical world where traditional medicine and modern technology fiercely collide, he started out as a despised low-level doctor. With his expertise in systematically integrating Chinese and Western medicine, he repeatedly solved difficult diseases in emergency rescues, academic summits, cross-border rescues and other scenarios. For example, he used traditional Chinese medicine to conservatively treat gastric perforation, and used gene editing technology to cure rare diseases. In an open and covert battle with Zhou Ming, deputy chief physician of a tertiary hospital, he exposed his conspiracy to collude with the mysterious and dark pharmacist association.
