Chen Mo, a graduate student in the Department of Modern History, accidentally traveled to the Taihe period of Cao Wei, which coincided with the beginning of Sima Yi's military power. He has no extraordinary martial arts or extraordinary powers. He only relies on the solid historical context in his mind and his thorough understanding of the general trend of the Three Kingdoms to join Sima Yi's command.
From guarding Jingxiang to resist Zhuge Liang's Northern Expedition, to offering advice to quell the Gongsun Yuan Rebellion in Liaodong, and then lying in wait to assist in the Gaoping Ling Revolution, Chen Mo always hid behind the scenes, assisting Sima Yi with strategies that suited the current situation. He avoided historical detours, resolved internal constraints, coordinated the relationship between generals, and cleared obstacles for the Sima family in troubled times.
He witnessed the undercurrents of the Wei and Jin changes, experienced the war-torn competition in the Central Plains, and used mortal wisdom to deal with the Cao Wei clan, aristocratic families and hostile camps. There is no miracle that changes destiny, only step-by-step planning, and finally assists the Sima family in three generations of management, wiping out Wu and Shu, ending the troubled times, realizing the unification of the world, returning peace to the nine states, and allowing this magnificent history to reach a predetermined but more profound ending with his participation.
