In the Tang Dynasty, It Rained Slightly, but the Doctor's Heart Was Not Disappointed.

Lin Wei, a modern medical student, accidentally traveled to the prosperous Tang Dynasty. He relied on his "silver medical needle" (forged by alchemists in the Tang Dynasty, which can detoxify, provide early warning, and sense fluctuations in time and space) and modern medical knowledge to save lives and heal the wounded in troubled times. She met the upright General Xiao Che who guarded the border. From the life-and-death protection during the war in Tongguan, to the medical and military side-by-side during the Chang'an epidemic, and then to the stable defense in Shazhou during the years, the two worked together to solve the conspiracy between the remnants of the feudal town and Tubo, and uncovered the secrets of the alchemist's ruins (Gate of Time and Space, Soul-Eating Fog, and Time-and-Space Afterimage). Finally, she resigned from power and retired to Shazhou to found "Huimin Medical Center" compiled "Shazhou Medical Records", integrated the medical skills of the Central Plains, the Western Regions, and Persia, built a bridge of cross-regional medical connections, and wrote a story of love and inheritance across time and space in which "medical knowledge spreads thousands of miles and protects the world affectionately."
