Emergency doctor Chu Tianqing accidentally traveled back in time to the Zhenguan period of the Tang Dynasty. He was bound to the "Modern Community Hospital" system and used modern medical skills and advanced equipment to open private clinics to treat diseases and save lives. He treated Empress Changsun who had an asthma attack, diagnosed Li Shimin's hypertension, and cured Cheng Yaojin's high fever. He shocked the government and the public with his miraculous medical skills. After becoming brothers with Li Shimin, resolving disputes between powerful people, and promoting first aid knowledge, he not only gained points to upgrade equipment, but also won people's hearts. He eventually became the legendary doctor of the Tang Dynasty, and was involved in emotional entanglements and palace adventures.
