Chen Yan, a modern history enthusiast, accidentally traveled to Liangzhou in the late Eastern Han Dynasty. It happened to be a time when Ma Teng's camp was experiencing internal and external troubles - the alliance with Han Sui was crumbling, Cao Cao's forces were pressing harder, and although the northwest army was brave, it lacked structure.
He has no extraordinary power, only a solid historical context in his mind and a simple knowledge of political and military management. Relying on his prediction of the current situation, he first persuaded Ma Teng to clean up military discipline, clarify food routes, and consolidate the foundation of Liangzhou with a combination of agricultural warfare; before the conflict between Ma and South Korea intensified, he proposed a mutually beneficial alliance to resolve the rift and unite the power of the northwest.
After that, he followed Ma Tengnan to reject Cao Cao and the Eastern Alliance princes, and made side attacks at key nodes such as Guandu and Chibi to make up for the shortcomings of the Northwest Army with strategies that were in line with the times. From the border separatism to the struggle for the Central Plains, Chen Yan, as a commoner, assisted Ma Teng to escape from the historical tragedy, step by step to build the Northwest Iron Cavalry into the core force to end the troubled times and unify the country, and blazed a new road to recovery in the war of the late Han Dynasty.
