Chen Yan, a graduate student in the Department of Modern History, accidentally traveled to Jiangdong in the second year of Xingping in the Eastern Han Dynasty. It happened to be when Sun Cegang led his troops to pacify Danyang and wanted to conquer Jiangdong. He does not have any extraordinary abilities. He only relies on his familiarity with the historical trends of the Three Kingdoms. He started as a low-level clerk, and gradually won the favor of Sun Ce by accurately predicting the situation of the Lujiang war and providing suggestions to appease the Jiangdong nobles.
After that, he assisted Sun Ce to avoid the disaster of Xu Gong's disciples and consolidate the foundation of Jiangdong; he also proposed the strategy of "paying equal attention to agriculture and warfare", built water conservancy, reorganized armaments, and promoted the rise of Jiangdong's economy and military power. Facing separatist forces such as Cao Cao and Liu Bei, he took history as a lesson and proposed the strategy of "uniting Jing to resist Cao and slowing down Bashu" to help Sun Ce gradually break through geographical limitations and advance step by step towards the goal of unifying the world and revitalizing the Han Dynasty. He used mortal wisdom to rewrite the fate of Sun Ce's camp in troubled times and write a unique chapter of the unification of the Three Kingdoms.
