Biologists of the Song Dynasty Started with Vegetation as Soldiers.

Li Yiheng, a doctor of biology, went deep into the Shiwanda Mountains of Guangxi to search for the legendary miracle drug "Lan Xianyi" in order to save his mother who was suffering from late-stage Parkinson's disease. He fell into a rift in time and space. When I opened my eyes again, it was already 988 AD, the Northern Song Dynasty. There is no system, no martial arts. He only has a little knowledge of botany, microorganisms and biochemistry and pharmacology. The sumach trees, wasps, and poisonous weeds in the mountain forest have all become weapons for his survival. From the Liao people's village to the Bianjing court, from the salt-alkali wasteland to the battlefield of Shu, he farmed, prevented epidemics, trained troops, and ran new schools, imprinting the method of studying things into this era. While he was looking for a way back, he was also digging a new road for the Song Dynasty.
