Chen Xi, a college student in the Department of Modern History, accidentally traveled to Gongsun Zan's army in the late Eastern Han Dynasty. At that time, many heroes were rising together. Although Gongsun Zan supported the elite white horses and righteous followers, he was trapped in strategic shortsightedness and lack of internal affairs. Chen Xi, who has no system and no golden fingers, relied on modern knowledge and understanding of historical trends to gradually gain Gongsun Zan's trust, starting from improving farm tools and organizing farm fields. He made suggestions to improve weapons and rebuild intelligence networks. He reversed the defeat in the Battle of Jieqiao with the help of suspicious soldiers. He also advocated uniting with Xianbei to defeat Wuhuan and stabilize the foundation of the north. Facing powerful enemies such as Yuan Shao and Cao Cao, Chen Xi strategized and helped Gongsun Zan burn the enemy's supplies during the confrontation in Guandu. Then he sent his troops south to unify the world with the strategy of uniting vertical and horizontal alliances. Finally, he assisted Gongsun Zan in establishing a new dynasty, starting a legend that rewrote history with modern wisdom.
