The Assassin King of Tang Dynasty

He traveled to the Sui Dynasty and became Li Yuan's adopted son and became a confidant with Yang Guang, but in the end he had no choice but to watch Yang Guang hang himself. He had a good relationship with Li Jiancheng and Li Shimin, but he still could not prevent the Xuanwu Sect. In the end, he could only go to the west, but he became the most powerful empire in history.
