Chen Mo, a graduate student in the Department of Modern History, unexpectedly traveled back to the late Eastern Han Dynasty after an accident in a museum and became an inconspicuous staff member under Yuan Shao. At that time, Yuan Shaogang had just defeated Gongsun Zan, and was sitting on the four prefectures of Ji, Qing, You, and Bing. He seemed to have a strong army, but in fact, there were internal factions, advisers had their own agendas, and they lacked vigilance against potential forces such as Cao Cao and Liu Bei. Chen Mo, who is well aware of the direction of history, has neither systematic blessing nor fantasy powers. He can only rely on his solid accumulation of historical materials and insight into human nature to survive step by step in the treacherous Ye Shogunate. He needs to first resolve the factional conflicts between Feng Ji, Shen Pei, Guo Tu, and Xin Ping, and then urge Yuan Shao to change his character flaw of "external tolerance and internal taboo", and then adjust his strategy and stabilize the rear before the Battle of Guandu, and finally assist Yuan Shao to consolidate the north, conquer Jingxiang to the south, and capture Jiangdong from the east, step by step, reverse history, help the Yuan Group break the fate of dividing the world, and realize the grand plan of national unification.
