Su Chen is an ordinary doctor in the emergency department of the No. 1 Hospital in the city, but his calmness, decisiveness and superb medical skills are far beyond ordinary people. He also hides a little-known golden finger - the emergency all-round system, which can analyze symptoms in real time and unlock top diagnosis and treatment technology. The emergency department is a battlefield of life and death, with emergencies happening every day, including serious injuries from car accidents, acute abdomen, and cardiac arrest. Every consultation is a race against death. Lin Hao, a malicious doctor in the same department, was jealous of Su Chen's talent and secretly tried to ruin Su Chen's career by stumbling upon him, stealing credit, and tampering with medical records. In the face of Lin Hao's difficulties and various serious problems, Su Chen always adhered to his original intention as a doctor. With calm judgment, superb medical skills and the help of golden fingers, he regained the lives of patients from the hands of death and resolved Lin Hao's conspiracy time and time again. From the ordinary doctor who was questioned, to the emergency department backbone who shocked the whole hospital, to the city-renowned emergency expert, Su Chen used a scalpel and a kind heart to become a god on the emergency front line, writing a passionate legend belonging to the emergency doctor.
