Chen Mo, a graduate of the Department of Modern History, accidentally traveled to Liaodong at the end of the Eastern Han Dynasty and joined Gongsun Kang's command. At that time, although the Gongsun family ruled in Liaodong, they were faced with the pressure of Cao Cao's power, the harassment of Goguryeo, and the difficulties of loose internal forces. The situation of partial peace was in danger.
Chen Mo has no golden fingers. He only relies on the historical context and modern governance thinking in his mind. He first provides Gongsun Kang with suggestions to rectify the government and promote high-yielding crops to improve people's livelihood. Then he helps him train troops and horses and improve ordnance to strengthen the military. He also provides suggestions to divide and disintegrate surrounding tribes, quell the troubles of Goguryeo and Wuhuan, and consolidate the foundation of Liaodong.
After that, he used the historical nodes of the aftermath of Guandu and the Battle of Chibi to formulate a strategy for Gongsun Kang to "sit back and watch the chaos in the Central Plains while accumulating strength to make progress", secretly united allies, encroached on the borders, and gradually included Liaodong and Youyan in the territory. From being safe in Liaodong to competing in the Central Plains, Chen Mo assisted Gongsun Kang with his mortal wisdom, rewriting the pattern of the Three Kingdoms step by step, and starting a road to unification that began in Liaodong.
