When Lin Fu, a modern history teacher, was studying the collected works of the Seven Sons of Jian'an, he accidentally traveled to the Yanzhou battlefield in the fifth year of Jian'an in the Eastern Han Dynasty. When he was captured by Cao's army in the rebellion, he became an aide under Ren Jun, the general of the army of Diannong, relying on his familiarity with the farming system. Without the powerful system plug-in, only the historical materials of the Three Kingdoms and agricultural knowledge in his mind, he implemented the regional planting method in Yanzhou to increase grain production, challenged the powerful when settling the case in Puyang, and sorted out the shortcomings of grain and grass dispatch before the Battle of Guandu.
With the rise of Cao Cao's power, Lin Fu gradually moved from the grassroots to the core of Cao Wei: checking the Yuan family's household registration in Yecheng, discussing politics with scholars at Tongquetai, following Cao Cao's northern expedition to Wuhuan to deduce the terrain, and refuting the false water war strategy before the Battle of Chibi. He personally experienced the undercurrent of the dispute between the princes and witnessed the political whirlpool of the Han, Wei and Zen dynasties. He not only clashed with counselors such as Xun Yu and Guo Jia, but also lamented the fate of Cao Pi and Cao Zhi.
When the wheel of history rolled over in the 25th year of Jian'an, Lin Fu stood in Luoyang City in the first year of Huangchu, watching the new emperor Cao Pi implement the New Deal, looking back on half his life on the sick bed - he was not a "man of destiny" who changed history, but a sober person who used a modern perspective to survive in troubled times. He used every subtle choice to write his own ups and downs in the Three Kingdoms era.
