He had just transmigrated into Li Chengdao, the son of Li Jiancheng, and encountered the incident at Xuanwu Sect. A large number of people were charging towards the Eastern Palace, determined to eliminate the root of the problem.
Li Chengdao led the Eastern Palace Crown Prince’s guards to attack Xuanwu Gate and escape from the Imperial City. They killed their way into the Heavenly Policy Manor and captured Zhangsun Wugou, Li Chengqian, and the others as capital to escape Chang ’an.
Li Shimin was not threatened, so Li Chengdao cut off Li Tai’s head in public.
In the confrontation between the two armies, he scolded Li Shimin for being a traitor and dragged Li Ke to death with his horse.
After escaping from Chang ’an, he raised his arm as the imperial grandson, and all four sides responded immediately. He brought millions of soldiers and charged back to Chang’ an.
Taiji Palace, angrily rebuked Li Shimin: Rebel, why don’t you kneel when you see me?
