At the end of the Eastern Han Dynasty, the time traveler Lu Fan brought his farming system to build a deserted village into a prosperous land county. He tried to avoid danger, trained his troops, opened banks, and built city walls. However, he accidentally bumped into Cao Cao and Xiahou Dun who were on their way to conquer Dong, and he also dealt with Mi Zhu and other merchants.
