In the 22nd year of Jian'an, Chen Mo, an ordinary history student, accidentally passed through Cao Wei and became a poor scholar in Hanoi County. At that time, Sima Yi was still under the command of Cao Pi and was hiding in the abyss. There was an undercurrent of competition for the reserve position within Cao Wei, and Shu and Wu were watching from outside. Chen Mo had no supernatural powers, but relied on his solid knowledge of the history of the Three Kingdoms to assess the situation and join forces with Sima Yi.
He made suggestions to stabilize Guanzhong's grain and grass to help Sima Yi fight against Shu, warned against Gongsun Yuan's sudden movements in Liaodong, and helped sort out Luoyang City's defense before the Gaoping Ling Incident. He never tried to reverse the historical trend. He only turned the hidden dangers in the history books into opportunities to break the situation at key points as a poor scholar, helping Sima Yi to resolve the criticism in the court and stabilize the military power.
From resisting Zhuge Liang's Northern Expedition to assisting Sima Shi and Sima Zhao in controlling Cao Wei, Chen Mo has always hidden behind the scenes, accompanying the Sima family through decades of ups and downs with his mortal wisdom, and finally witnessed the Western Jin Dynasty replacing the Wei Dynasty and the reunification of the nine states, and he also became the unknown "Mr. Assistant Government" in the Sima family's ancestral hall.
