In the seventeenth year of Kaiyuan, the Tang Dynasty was at its peak. Emperor Xuanzong and Li Longji worked hard to govern and the country was strong. However, there were hidden dangers inside the court (treacherous ministers were in power and party disputes began). The borders were not peaceful. Turkic tribes frequently harassed the borders of Hexi and Anbei, and small-scale wars continued. At this time, Li Zhaosheng returned to the point where he first entered the military camp and had not yet been involved in the core disputes. His wife and children were still there, and his enemies had not yet arisen. Everything was possible to be undone. He must not only gain a foothold in the military camp, accumulate strength, and deal with the upcoming large-scale border war, but also guard against traitors in the court and military camp, protect his family, and at the same time uncover the mysteries of his past life and avenge bloodshed.
