Lin Fu, a graduate student in the Department of Modern History, traveled to the late Eastern Han Dynasty after an accident, which coincided with the time when Cao Cao first took control of Yanzhou and recruited talents. He has no extraordinary powers and only relies on the solid historical context and pragmatic understanding in his mind to recommend himself to Cao Ying. At first, he was cautious and cautious, and he distinguished himself by his practical work such as grain and grass dispatching and household registration, and gradually gained Cao Cao's attention and trust.
After that, he predicted Yuan Shao's deployment before the Battle of Guandu and made suggestions to complete the details of the surprise attack on Wuchao; on the eve of Red Cliff, he urged Cao Cao to be wary of fire attacks, stabilize the navy, and avoid historical defeat; and after pacifying the north, he proposed the strategy of cultivating farming and reorganizing officialdom to accumulate national strength for Cao's army. He always abides by his duties as a subordinate, does not take credit for himself, takes history as a lesson but does not follow it blindly. In troubled times, he assists Cao Cao in integrating the north, conquering Jingxiang, and pacifying the south of the Yangtze River. Step by step, he reverses the historical trajectory, helps Cao Wei clear out the heroes, end the war, and ultimately unify the world, witnessing the rise of a brand new unified dynasty in the Central Plains.
