Daliang, a feudal dynasty that seems prosperous but is actually full of crises. Land annexation was serious, the imperial examination system was rigid, powerful enemies were watching from outside, and powerful officials controlled the government internally. The male protagonist traveled through time and became an emperor. He used modern thinking to unite with the "Four King Kong" in the harem to carry out land reform, technological rejuvenation, military expansion, and diplomatic disruption, transforming Daliang from a crumbling dynasty into a prosperous empire. "My harem is all pillars, and my country is all bricks. There are no useless women, only emperors who don't know how to use people."
