Modern young man Chen Mo accidentally traveled back to the late Eastern Han Dynasty and joined the army of Liaodong Gongsun Kang. At that time, the Central Plains was raging with war. Cao Cao, Liu Bei, and Sun Quan each occupied one side. Although the Gongsun family was sitting in Liaodong, they were trapped in the border areas. Wuhuan and Goguryeo were watching outside, and they lacked food, grass, and soldiers inside. It was difficult for them to have a say in the competition among the heroes.
Chen Mo had no extraordinary power, but relied on the historical context and superficial knowledge of governance in his mind. He proposed to Gongsun Kang the strategy of reclaiming wasteland and accumulating grain, and improving agricultural tools to increase the yield per acre. He also suggested training the frontier troops, learning from the Central Plains' military methods to make up for the shortcomings of the Liaodong cavalry, and at the same time pacifying the surrounding Hu people in Sui and stabilizing the rear.
During Cao Cao's northern expedition to Wuhuan and Sun Liu's confrontation with Jingzhou, Chen Mo assisted Gongsun Kang in setting up a camp step by step, first taking over the Liaodong counties, and then trying to conquer Youyan, gradually growing from a border force to a force that could compete with the princes of the Central Plains, and finally embarked on a journey to conquer the Central Plains, end the troubled times, and help Gongsun Kang unify the world.
