Chen Yan, a graduate of the Department of Modern History, unexpectedly traveled back to the late Eastern Han Dynasty and became an unknown minor official under Ma Teng, the warlord of Liangzhou. At that time, Dong Zhuo's chaos was just over, and the Central Plains princes were separatist. Liangzhou was located on the border, barren and chaotic. Although Ma Teng's forces had elite cavalry, they were subject to internal and external difficulties. There were Qiang and Barbarian attacks in the west, and powerful neighbors such as Cao Cao and Yuan Shao in the east. The fate of the father and son was already doomed to tragedy.
Chen Yan has no golden fingers, only a thousand years of historical knowledge and a pragmatic mind. He devoted himself to assisting Ma Teng. He first offered strategies to pacify the Qiang and Hu tribes, integrated Liangzhou's internal forces, and then implemented the strategy of colonizing valleys to enrich military resources. During military training, he innovated the method of formation warfare, exploiting strengths and avoiding weaknesses to create elite cavalry.
Faced with the chaotic situation of heroes vying for the throne, he sized up the situation, helped Ma Teng unite alliances, divide powerful enemies, avoid the fatal traps in history, and steadily advance eastward based on Longyou. From pacifying Liangzhou to competing in Guanzhong, and then commanding the Central Plains, Chen Yan fought side by side with Ma Chao and others, making up for the shortcomings of power with wisdom and overcoming the difficulties of fortune with perseverance, gradually reversing the fate of Ma Teng's camp, vowing to support Han Zuo from decline and unify the world in this troubled time.
