The social worker Chenze died suddenly while working overtime. When he woke up, he became a prisoner in Lishan Mountain of the Qin Dynasty. He was about to be "killed to scare the monkeys" by the supervisor. At the critical moment, a mysterious middle-aged man rescued him and said only: "You are like an old friend of mine." He did not know that this man was Qin Shihuang, let alone that he was the illegitimate son of Qin Shihuang. One wants to admit it but can't, and the other doesn't know whether he should admit it or not. Let's look at the time traveler Chen Ze, who brings systematic farming infrastructure and technological power to the country, and joins forces with his father to rewrite the fate of the Great Qin II.
