Chen Mo, a modern history enthusiast, accidentally traveled to Liangzhou in the late Eastern Han Dynasty and joined Ma Teng's army. At that time, although Ma Teng had a separate army, he was in deep trouble: he was frequently harassed by Qiang and Hu in the west, suppressed by Cao Cao's forces in the east, and there were many internal disloyalty among the generals. Chen Mo has no extraordinary abilities and only relies on his familiarity with the situation of the Three Kingdoms and pragmatic strategies to start from the bottom of the staff.
He first offered suggestions to improve simple agricultural machinery and promote drought-resistant crops to alleviate the shortage of military food; then he assisted Ma Teng in training cavalry, divided and united the Qiang and Hu tribes, and gradually consolidated the foundation of Liangzhou. Subsequently, he advocated uniting with Jordan, avoiding the real and attacking the weak, and at the key node of the confrontation between Cao Cao and Yuan Shao, Liu Bei and other forces, he created an alternative development path for Ma Teng's camp and avoided the traditional mistakes.
In the turbulent times, Chen Mo used history as a guide to resolve several internal and external troubles, and promoted Ma Teng's forces from settling in Liangzhou to competing in the Central Plains, step by step towards the goal of unifying the world, and this period of late Han Dynasty history gradually took a different direction.
