Ying Zheng was born in Handan, Zhao. At that time, his father Qin Gui was a proton sent by Qin to Zhao. Later, a war broke out between Qin and Zhao, and Qin Gui fled back to Qin with the help of Lv Buwei. However, Ying Zheng and his mother stayed in Zhao's court. Because of the special status of mother Evonne, both mother and son survived.
Later, Qin made people reign and took Ying Zheng and his son back to the State of Qin. Three years later, thirteen-year-old Ying Zheng ascended the throne. Because he was too young, the power of Qin was in the hands of the Prime Minister and other officials.
Ying Zheng's biological mother, Evonne, used to be Lv Buwei's concubine. Because she was taken back by the Qin barbarians, she gave birth to Ying Zheng. After the death of Qin makes, the two rekindled their old love, regardless of the young Ying Zheng's face, and often had private meetings in the palace. Although this matter has not spread on the surface, people will talk privately that Ying Zheng may be Lv Buwei's son.
With the growth of Ying Zheng, Lv Buwei wanted to get away as soon as possible, so he recommended Toy Boy Ai to Evonne. Ai's behavior is even more absurd. He and Evonne successively gave birth to two sons, and proclaimed himself Ying Zheng's father. He also negotiated with Evonne to kill Ying Zheng and make his son emperor.
At this time, Ying Zheng has gained a foothold in Qin. After several years of forbearance, he decided to solve his mother's problem once and for all. He ordered a thorough investigation and killed Ai Checha, Zhu Sanzu and Evonne. He also announced that he would sever the mother-child relationship with Evonne and move Evonne to a remote and harmonious place.
Ying Zheng doesn't want to let his mother's old lover Lv Buwei go, but Lv Buwei's influence in North Korea is not small, so it is not easy to do it directly. Ying Zheng withdrew its rights. First, he dismissed Lv Buwei as prime minister, and then ordered him to move to Shu. Lv Buwei looked at his hard-earned power and wealth for decades, and thought that the king of Qin would kill himself sooner or later, so he drank the poisoned wine and committed suicide.
