This play is the third in the series of Daqin Empire. It tells the story of the King of Qin, with the help of Xuan Di, Bai Qi and Li Qi, who weakened the six countries and conquered Jiuding, and laid the foundation for the great-grandson Qin Shihuang to unify the world many years later.
The main plot is: Soon after Qin came to power, countries launched a series of merger wars. The State of Qin seized this opportunity and joined forces with Qi Lian Heng to plunder the vast land of Wei. As a result, the Warring States reached the stage of the three pillars of Qin, Qi and Zhao. At this time, the State of Qin and Wei Ran were in power, the Empress Dowager Xuan was in power, and the kingship of Qin was sidelined. At this time, the situation was very favorable to the State of Qin: Su Qin, a military strategist, secretly made an appointment with the prince to go to the State of Qi to "destroy" the State of Qi with the goal of destroying it. Faced with domestic political difficulties and favorable opportunities abroad, Qin Zhao and Wang Yiran began to use Fan Ju to expel Wei Ran and abolish the power of Empress Dowager Cixi.
At the same time, in collusion with Su Qin, the soldiers attacked Qi. Zhao Haoqi of Qin sent his generals to Leitian, and successively launched four major battles, namely, Yi Que, Ying Du, Huayang and Changping, and wiped out more than one million troops in the four dynasties of Han, Wei, Qi and Chu, which made a fundamental turning point in the rise and fall of Qin and other countries. Since then, the state of Qin has risen.
