The State of Qi wrote a letter to Qin, saying that it was willing to use the country as a betrothal to marry Princess Ji Wei to the King of Qin. However, there are three requirements: first, Qi's appointment will only take effect after Qin unifies the remaining five countries, and Qi will surrender without a fight; second, Qin must promise not to attack any country for three years after marrying Princess Ji Wei; third, Qin Wangzheng's harem cannot admit another person. As soon as this letter came out, everyone in the world was shocked. They marveled at the virtuousness of the king of Qi for his country's efforts to bring peace to the world after three years of war. However, I don't know that Qi's intention is to internalize Qin, and its plan is that when Qin unifies the world, the country's name will be Qin, and the country's system will be Qi. Let's see how Princess Ji Wei solves the crisis of Qin and transforms Qin into Qi.
Purpose: Only benevolent government can rule the world
