At the end of the Warring States Period, King Qin Zhuangxiang's son Ying Zhao was trapped in Handan as a hostage. His mother Zhao Ji was bullied by Zhao's powerful men, and when she was about to die, she activated the "Emperor's Hegemony System." The system gives progressive scripts such as "Proton Counterattack", "Power to the Qin Palace" and "Unification of the Six Kingdoms". After completing the scripts, you can get rewards such as increased military force, the surrender of famous ministers, and the love of beautiful women. Ying Zhao began to endure and seek survival. He first slapped the Zhao generals in the face to save his mother, and then planned to escape back to Qin. Through the system, he helped conquer famous officials such as Li Si and Wang Jian, defeated powerful officials such as Lu Buwei and Lao Ai, and became the king of Qin. Then he swept through the six kingdoms, destroyed Han, Zhao, Wei, Chu, Yan, and Qi, and established the Qin Empire, claiming the title of First Emperor. In the process, he acquired Zhao Qingli, the princess of Zhao State, Tian Wenjiang, a talented girl from Qi State, Mi Yuechan, the mountain lord of Chu State, and other harems, and finally realized the ultimate script of "ruling the world".
