Lin Fu, a graduate student in the Department of Modern History, accidentally traveled to the end of the Eastern Han Dynasty during a compilation of ancient books. It happened to be the time when Gongsun Zan defeated Liu Yu and shocked the northern Xinjiang, and became an ordinary staff member under him. Lin Fu, who was fully aware that Gongsun Zan was defeated due to his stubbornness and improper strategy, was determined to reverse the trajectory of history on his own.
He concealed the secret of time travel, and gradually gained Gongsun Zan's trust with his solid historical literacy and pragmatic management strategies: he rectified the white horses and strengthened the cavalry's mobility and coordinated operations; he offered suggestions to appease the refugees in Youji, and implemented the farming system to stabilize the rear; he skillfully used conflicts among the princes to resolve Yuan Shao's pressing advances and avoid the mistakes of the Battle of Jieqiao.
Faced with the rise of Cao Cao, Liu Bei's dormancy, and Sun Quan's separatist rule, Lin Fu assisted Gongsun Zan in uniting the weak and controlling the strong, and steadily expanded. He not only has to deal with the flash of swords and shadows in troubled times, but also needs to reconcile the factional disputes within Gongsun Zan's camp, and he also needs to find hope in the turbulent game of princes.
A journey based on Youyan and with the goal of unifying Kyushu began. Lin Fu used his mortal wisdom to help General White Horse break his fate and compete for the world in the real chaotic times of the Three Kingdoms.
