Lin Fu, a student of the Department of Modern History, accidentally traveled to the Jiaping period of Cao Wei in the Three Kingdoms and became an inconspicuous staff member in Sima Yi's mansion. He has no extraordinary skills, and only relies on the solid historical context in his mind and his insight into the current situation of people's hearts to quietly become the core of the Sima camp. At that time, Sima Yi had power in both the government and the public, but he was suffering from internal and external troubles. Cao Wei's clan was jealous, Shu Han Jiang Wei's Northern Expedition, and Soochow Sun Quan were eyeing him. Lin Fu stayed dormant and endured, offering strategies to stabilize the situation before the Gaoping Ling Incident, optimizing logistics arrangements on the Guanlong line of defense, and helping the Sima family clear obstacles in the secret fight in the court. He did not take credit or violate the rules, and acted in a way that was in line with the times. He assisted Sima Yi to consolidate his power, helped the brothers Sima Shi and Sima Zhao integrate their forces, and avoided the historical setbacks in the process of unifying the Sima family. From appeasing the refugees, rectifying the administration, and formulating a strategic blueprint for conquering Shu and conquering Wu, Lin Fu used his meager efforts to promote the current situation, witness and participate in a great cause of unification that spanned decades, and finally assisted the Sima family to wipe out the world, end the troubled times, reunite the nine states, and write a historical chapter in which guests from other worlds helped rejuvenate the country.
