Datang: Kill Li Shimin at the Beginning

Chengxin: "Miss Zhuge, I know you are a descendant of Wuhou. I am Li Chengxin, yes, the one who killed Li Shimin. I will formally propose marriage to you now." Cheng Xin: "Miss Guan, I know that you have a prominent family and you are a descendant of the Martial Saint, but I, Li Cheng Xin, am not bad either. My father is the Yin Prince Li Jiancheng. We can be said to be a perfect match. It would be better to choose the right date than to meet the other. How about we get married today!" This novel and its characters are purely fictitious.
