Three Kingdoms: Starting from Wancheng to Save Cao Cao

Cao Zheng accidentally traveled to the Three Kingdoms period and became Cao Anmin's brother and Cao Cao's nephew. However, although the two are brothers, their personalities are completely different. Cao Anmin relies on relationships to follow Cao Cao, while Cao Zheng studied under a teacher when he was young and became Cao Cao's general by relying on his own ability when he grew up. The first thing Cao Zheng encountered after leaving the army was to save Cao Cao who was being chased by Zhang Xiu. After that, Cao Zheng helped Cao Cao conquer the world, trained new troops, founded a military academy, reformed the system, and finally became the regent of the Cao family and assisted four generations of kings until he died at seventy.
