Chen Mo, a graduate of the Department of Modern History, unexpectedly returned to the late Eastern Han Dynasty and joined the army of Liu Yan, who had just entered Shu. At that time, the world was about to be in chaos, the aftermath of the Yellow Turban was not over, and the feudal regimes were beginning to emerge. Although Liu Yan wanted to spy on the artifact, he was trapped in Yizhou's internal and external troubles. Chen Mo has no extraordinary power, and only relies on his understanding of the direction of history to assist Liu Yan in every detail. He made suggestions to stabilize the local power, straighten the administration, promote improved agricultural tools to increase grain, and practice new methods of recruiting troops to strengthen the military. When the princes were vying for the throne, he advised Liu Yan to avoid his edge, accumulate strength, recruit talented generals who had been buried in troubled times, and link up with reliable reinforcements to resolve fatal crises. From quelling the civil strife in Yizhou to competing for important areas in Hanzhong, from checking and balancing Cao Cao and Liu Bei to disintegrating the Jiangdong Alliance, Chen Mo used ordinary people's wisdom and worked step by step to help Liu Yan and his son consolidate their foundation, and gradually became a force sweeping the world. This is a journey of hegemony based on the real historical framework, using wisdom to turn things around, assist the Yizhou Group to break through its destiny, point its sword at the Central Plains, and pacify the world.
