In 626 AD, the Xuanwu Gate uprising broke out and the Eastern Palace was massacred. Li Chengdao, the son of Li Jiancheng, led the old officials of the Eastern Palace to flee Chang ’an and enter Europe from the Western Regions.
Ten years later, Li Chengdao destroyed the Eastern Roman Empire and established the Great Qian Empire.
Under the watchful eyes of countless Roman citizens, he ascended the throne like a god and proclaimed himself emperor in Constantinople.
Holy Emperor!
On the day of his ascension, the envoys of the Abbasid Caliphate, the Persian Empire, India, and the countries of the Western Regions prostrated themselves on the ground, and all the countries submitted.
Three months later, Li Chengdao gathered his troops and personally led the expedition. With the Han army as the main force and the Roman slaves as the logistics, he crossed thousands of miles from the Western Regions to kill his way back to the Great Tang!
When the horse was in Chang ’an, Li Chengdao was sitting on the dragon chair in Taiji Hall. Wei Zheng scolded Li Shimin,""You are a traitor who killed your brother and forced your father. Why didn’t you bow to the Great Qian Emperor?”
