Chang Cheng, who majored in modern history + logistics, traveled back in time during the Yellow Turban Rebellion in 184. He was appreciated by Cao Cao for proposing the "fire attack to protect food + temporary compilation of refugees" policy and was appointed as a logistics officer.
With the help of the prophet, he defeated the Yellow Turbans in Yanzhou (creating the farmland system), attacked Wuchao in Guandu (cut off Yuan Shao's grain), and designed a light grain road for the northern expedition to Wuhuan. The defeat in Chibi ensured the retreat of Cao's army.
He helped Cao Pi replace the Han Dynasty and establish the Wei Dynasty, establish the country's farmland, grain roads, and disaster prevention systems, and provided logistical support to destroy Shu and defeat Wu. He eventually became the founding father and laid the foundation for Cao Wei's unification of the three kingdoms.
