Modern historian Chen Mohun returned to the late Eastern Han Dynasty and joined Cao Cao's camp. When Bianshui was defeated, he advocated preserving fire and implemented the method of "dividing fields and fixing rents" in Yanzhou; before the Battle of Guandu, he predicted the flaw in Yuan Shao's grain road and made suggestions for a surprise attack on Wuchao; before the Battle of Chibi, he admonished Cao Cao to be wary of the danger of serial ships, but in the end it was difficult to reverse the east wind. He assisted three generations of the Cao family, defeated Ma Chao and the Han military system in Weinan, put down the rebellion in Huainan, and helped Cao Wei lay the foundation of the Central Plains with pragmatic strategies. When the Sima clan rose to prominence, he secretly arranged for Yanghu to farm and Wang Jun to repair ships, and hid the strategy of "going down the river and attacking both land and water" to destroy Wu in the "Military of Water Wars". In the end, the Western Jin Dynasty navy defeated Jianye, and Chen Mo stood on the stone city, watching the dust of the three-point unification settle down - he did not change the general trend of history, but used mortal wisdom to find a moment of peace for the people in the turbulent flow of the late Han Dynasty, and witnessed the inevitable transition of an era from division to integration.
