Chen Yan, a graduate student in the Department of Modern History, accidentally traveled through time while inspecting the ancient battlefields of the Three Kingdoms. It happened to be the eve of the confrontation between Yuan Shao and Gongsun Zan at the Jie Bridge in the third year of Chuping, and he became a refugee outside Yuan Shao's military camp. Relying on his familiarity with the history of the Three Kingdoms and basic modern common sense, he was fortunate enough to be recommended by Chun Yuqiong to meet Yuan Shao. Although he did not show his "prophet" edge, he was temporarily trusted with his pragmatic grain and grass management suggestions and battlefield investigation ideas. Since then, he has been deeply involved in the factional disputes between Yuan Shao Group's internal review, Feng Ji, Guo Tu, and Xin Ping. He must not only avoid the risk of Yuan Shao's suspicion and indecisiveness, but also at key points such as the Guandu confrontation and the Jingzhou game to improve warehousing, rectify military discipline, and distribute Strategies such as transforming enemy camps gradually reversed the decline of Yuan Shao's camp, helping him pacify Gongsun Zan, disintegrate Cao Cao's alliance, and subdue Liu Biao's forces. Ultimately, he promoted the Heshuo army to sweep the world and find a path to unification in troubled times that was very different from history.
