Lin Fu, a graduate student in the Department of Modern History, accidentally traveled to the late Han Dynasty when Sun Jian was on his way to conquer Dong. In troubled times, there is no golden finger around, only the detailed historical context and pragmatic principles of conduct in the mind. He was well aware of the glory and regret of Sun Jian's camp, and was determined to assist Sun Jian in changing his destiny with his meager strength.
Lin Fu relied on his accurate prediction of the current situation to help Sun Jian avoid hidden arrows, integrate the old troops in Jiangdong, and consolidate his foundation; he offered suggestions to appease the nobles, encourage farmers to save food, grass, and soldiers; he also maneuvered in the alliance against Dong to gain a favorable situation for Sun Jian. He didn't just talk, he only pursued practical work, from improving military discipline to improving ordnance, from contacting allies to dividing enemy camps, he worked step by step.
With his assistance, Sun Jian was no longer a tragic hero who died young. The Jiangdong cavalry swept across Jingyang, then rejected Cao Cao in the north, defeated Yuan Shao in the east, and pacified Bashu in the west. In the war of troubled times, Lin Fu and Sun Jian's father and son worked side by side, controlling the troops with benevolence and breaking the situation with wisdom. In the battle of swords and power, they reversed the trajectory of history step by step, moving forward towards the goal of unifying the country and ending the troubled times, and wrote a new chapter of the struggle for hegemony in the late Han Dynasty.
