Lin Fu, a graduate of the Department of Modern History, accidentally traveled to Nanjing Middle School in the third year of Jianxing. On the eve of Zhuge Liang's southern expedition, he was trapped under Meng Huo's command. At that time, various tribes in the south and central were fighting. Although Meng Huo had prestige, he lacked a strategy. The Shu Han was suppressing the territory in the north, and Sun Wu was coveting it in the east. Lin Fu relied on his solid historical understanding and basic agricultural and industrial knowledge to help Meng Huo integrate tribes, improve farm tools, and train soldiers. He first relieved the Shu Han from the difficulties of conquering the south, and then united with the southwestern tribes to consolidate their foundation and gradually escape from the fate of "seven captures and seven manipulations." He broke through the Three Kingdoms from a southern perspective. Amid tribal suspicions and powerful enemies, he helped Meng Huo move from the leader of the South to the stage of competing in the Central Plains, trying to rewrite the fate of Pian An and create a different outcome of the Three Kingdoms.
