Tang Dynasty: Li Jiancheng, the King, Returned to Chang'an and Proclaimed Himself Emperor

With only three days left before Xuanwu Gate, Li Jiancheng received a piece of news from the future. [The changes of Xuanwumen, the rule of Zhenguan, Li Shimin became the emperor through the ages...] Many news show that he is no longer the second Tang emperor after Li Yuan. Knowing the news about the future, Li Jiancheng immediately made various plans. "What! I didn't see the prince in Xuanwu Gate, and I didn't see the prince in the East Palace either? Where are the others?" "Damn it, where are the people, where are the people!" Li Jiancheng disappeared. Although the Xuanwumen incident was still won, it seemed that he had not won. The King of Qin and everyone in the Prince's Palace were always uneasy and worried about the return of that person... The orthodox of the Tang Dynasty!
