Ding Chen, a student of modern history, traveled through time and became Ding Chen, the nephew of Cao Cao's original wife, Mrs. Ding, who coincided with the rebellion of Zhang Xiu in Wancheng. He warned in advance to save Cao Ang, who was supposed to die, and cleverly used suspicious soldiers to coerce the people to force Zhang Xiu to surrender for the second time. After receiving the title of Tian Ling from Yiyang, Ding Chen found a secret copper mine, recruited refugees with wages to mine and smelt copper, subdued the fierce general Wei Yan, and held the lifeline of making money. In the troubled times of the late Han Dynasty, he took root in business and made money while leveraging the power of the Cao family to rise step by step.
