At the Beginning, He Forged an Imperial Edict to Scare Li Er.

A young man in the 21st century wakes up and becomes Li Ke, the third son of Li Shimin. At this time, on the eve of the Xuanwumen Incident, Li Shimin had not yet made up his mind whether to kill his brother and his father. Li Ke, knowing full well that he would be tolerated by his eldest grandson Wuji and destined to have a miserable future, decisively forged Li Yuan's imperial edict to kill Li Jiancheng and directly put Li Shimin on the throne. Since then, Li Ke has won great favor from Li Shimin, Yuchi Gong, Fang Xuanling and other former officials of the Qin Palace. … A few years later, Li Ke's reputation overshadowed that of the Tang Dynasty, and the people called him the Holy Prince. Li Chengqian's position as heir apparent was greatly threatened. Above the court, Changsun Wuji and Hou Junji framed Li Ke for rebellion, and Li Shimin believed the slander. In a desperate situation, Li Ke cut off Changsun Wuji's head with a sword, ordered the dragon cavalry to trap the Tai Chi Palace, and looked at Li Shimin with a dull look: "Since my father believes that my son is rebelling, I should just rebel."
