In the first year of Zhenguan, 16-year-old modern boy Lin Xiaoman accidentally traveled through time. He took the "Family First Aid Manual" left by his parents and opened "Xiaoman Medical Clinic" in Liujia Village outside Chang'an City. He used modern medical knowledge to break the dysentery epidemic, make alcohol for disinfection, and create isolation therapy to deal with measles. He also broke the old custom that "women are not allowed to study medicine", founded a medical school, and trained folk doctors. The whole book combines the spirit of Zhenguan and the spirit of fireworks, and tells the story of the young doctor's benevolence and perseverance across time and space, as well as the chapter of saving the world resulting from the collision of modern medicine and ancient wisdom.
