Chen Mo, a modern history enthusiast, accidentally traveled to the Jianxing period of Jihan Dynasty, which coincided with the key point of Zhuge Liang's Northern Expedition and joined the army of the later master Liu Chan. He does not have any extraordinary abilities. He only relies on his familiarity with the history of the Three Kingdoms and basic modern understanding to assist Ji Han in every detail.
He first improved agricultural tools and promoted drought-resistant crops to boost mulberry farming in Shu and alleviate the grain shortage in the Northern Expedition; he also organized grain road stations, optimized logistics supply efficiency, and provided stable support for the front line. At the court, he tactfully advised Liu Chan to balance the forces of various factions and reuse capable ministers such as Jiang Wan and Fei Yi to prevent eunuchs from interfering in politics.
After Zhuge Liang died of illness, he helped stabilize the government and proposed to Jiang Wei a new strategy for the Northern Expedition of "steady defense and encroachment" to reduce unnecessary losses. Externally, he used historical context to cleverly drive a wedge between the Sima family of Cao Wei and the Cao family. At the same time, he contacted Soochow to contain Cao Wei, and gradually disintegrated the hostile camp.
Over the decades, Chen Mo used his mortal power to assist Liu Chan in gradually reversing the decline of the Ji-Han Dynasty, and finally led the Shu army to conquer Luoyang, reunifying the Han Dynasty and completely rewriting the historical regret of "luckily thinking about Shu".
