Introduction: Zhang Lin, a modern social animal, takes the "civilized infrastructure system" and travels to a low-civilized world where wars are frequent. The beginning is a dilapidated village with only four walls. The system does not give him magic weapons, but only teaches him how to dig wells, plow fields, smelt iron, and build cities. From providing food and clothing for a village to establishing institutional order, from resisting bandits to connecting city-states, he used modern knowledge to illuminate the wilderness, used the power of infrastructure to leverage the progress of civilization, and finally built a continent-wide civilized empire on this land.
