I Am the Medicine Emperor

A university PhD in agriculture inexplicably transmigrates to the cultivation world. Using his agricultural expertise, he improves spiritual herbs and medicines, gaining resources and growing stronger. Along the way, he cultivates hybrid rice and improves farming tools and crops, helping ordinary people live happier lives. By consolidating the resources of cultivation sects, he increases his cultivation and becomes a powerful figure in the cultivation world. When foreign enemies invade, he leads the entire cultivation world in resisting them, and ultimately attains the Dao and ascends to immortality.
