Datang: No, There Is Only One Prince Today!

Traveling through Wude for nine years, he became Li Chengqian, the eldest son of General Tiance Li Shimin. There are still thirty days left before the Xuanwu Gate incident! This time, it's the other way around. There is only one prince today, and that is me, Li Chengqian! ! ! Li Jiancheng: "Oh no! Fourth brother, didn't you say you have made all the arrangements? Why in this Xuanwu Sect, we are completely suppressed by the second brother and the others!" Li Yuanji: "Brother! What a variable! This little bastard Li Chengqian is the biggest variable! He actually called me a uglier person! I'm so angry!" Li Chengqian: "Li Shimin, with the gun in hand, follow me! After the Xuanwu Gate Incident, I will make you the crown prince! After the Changle Gate Incident, you have to beg me to be the emperor!" Li Shimin: "Cheng Qian! Who is the father of whom among us? Also, can I really only sit on this throne for one morning?" Yuchi Gong: "I am a die-hard fan of Li Chengqian. When he asked me to kill Li Shimin, I didn't hesitate!" Empress Changsun: "Chengqian, you actually asked me to help you be a matchmaker with Zheng Guanyin and Princess Chao! Isn't this ridiculous! It messes up the hierarchy!!" Thirty-six Kingdoms of the Western Regions and Eighteen Tribes of the Grassland: "Give me the honorific title for the Emperor of the Tang Dynasty! He is called!! Heavenly Khan!!!"
