In a county town that was conquered by the rebel army and reduced to wasteland, Li Mo, a Ph. D. In history who traveled through time and became a down-and-out scholar, used the modern military database in his mind to start by instructing farmers to dig toilets and build isolation areas. He then used standardized systems and industrialized thinking to rebuild social order, and finally built the "Three No Matters" zone into a military and economic fortress to crush the feudal princes.
