Lin Fu, a graduate student in the Department of Modern History, accidentally traveled to the sixth year of Zhongping, when Dong Zhuo was in chaos and the world was about to collapse. He was alone and helpless. With his accurate understanding of the general trend of the Three Kingdoms, he surrendered to Cao Cao under Chen Liu. At first, he was just a low-level staff member, but Lin Fu repeatedly offered good advice with pragmatic strategies: he advised Cao Cao to welcome Emperor Xian as soon as possible to serve the emperor, he offered suggestions to improve the farming system and stabilize the rear, he predicted Yuan Shao's deployment before the Battle of Guandu to help Cao's army surprise Wuchao, and he tried his best to warn Cao Cao on the eve of Red Cliff to prevent fire attacks, but he failed to follow the situation due to the current situation. He dealt with top advisers such as Xun Yu and Guo Jia, neither showing off nor hiding his clumsiness. He optimized the military and political system from a modern perspective, rectified the administration of officials, and improved ordnance technology, and gradually became Cao Cao's right-hand man. From pacifying the north to commanding troops south of the Yangtze River, Lin Fu witnessed and participated in the rewriting of historical nodes one by one, assisted Cao Cao in resolving internal and external troubles, and united people's hearts. Finally, after decades of war, he wiped out Wu and Shu, unified the world, ended the troubled times, and created a new dynasty in which the four seas were reunited.
