Three Kingdoms: Saving Cao Cao at Wancheng

Cao Zheng accidentally transmigrates to the Three Kingdoms era, becoming Cao Anmin’s twin brother and Cao Cao’s nephew. Though the two are brothers, their personalities are completely different. Cao Anmin relies on his connections to follow Cao Cao, while Cao Zheng studies under a master in childhood and grows up to become one of Cao Cao’s leading generals through his own abilities. The first thing Cao Zheng does after completing his training is rescue Cao Cao, who is being pursued by Zhang Xiu. From then on, Cao Zheng helps Cao Cao conquer the land, train a new army, establish a military academy, and reform the system. In the end, he becomes regent of the Cao clan, serving four generations of rulers before dying at the age of seventy.
