Modern man Zhao Yufan traveled through time and became the second son of the Qin Dynasty. Knowing that he would be executed by Hu Hai if he did not change, he pretended to be stupid and went to Sanchuan County to take up a post. In Sanchuan County, he used the knowledge of later generations to develop the economy, recruit talents, develop firearms, and secretly prepare for power. The sudden death of Qin Shihuang disrupted the plan. Zhao Yufan quickly deployed and ordered Han Xin to lead his army to surround Xianyang, using internal agents and red cannons to build momentum. After entering the city, he killed the treacherous ministers, took control of the situation, suppressed the anti-Qin forces with thunder, and revolutionized the government. Qin Shihuang, who faked his own death as a test, was also shocked by Zhao Yufan's actions, and a change concerning the fate of the Qin Dynasty began.
