An entire modern residential community, complete with all its facilities and a population of one hundred thousand, transmigrates along with its land to a primitive otherworld resembling the Spring and Autumn period. The head of the residents' committee is forced to become the "city lord," leading a group of modern citizens skilled at lying flat, cutthroat competition, and filing complaints. Using property-management methods, the Civil Code, and the productivity of cutthroat competition, they reshape the rules of civilization for an entire age.
