The Great Fan Kingdom was founded by the Baili clan and coexisted with the Lang clan across the mountains, with constant warfare. The Fan Emperor and the crown prince passed away one after another, and the younger son of the emperor, Baili Hao, ascended to the throne. At that time, Hao was still very young, so his mother, Empress He, assisted in governance. Although the late crown prince's sons, Baili Hongxuan and Baili Hongshuo, were loyal to the young emperor, and Baili Hongxuan frequently achieved military victories to ensure the safety of the people of the Fan Kingdom, Empress He, influenced by treacherous ministers, remained wary of the two brothers. Although the young emperor trusted the brothers and intended to support them, he was also limited in his capabilities. The new leader of the Lang clan, Ming Yefeng, discovered the true identity of Baili Hongyi, the daughter of the Plain King, and the mystery of Hongyi's background pushed the Baili clan toward the abyss. At this time, a mysterious figure noticed unsettling signs emerging in the royal city of Yecheng in the Fan Kingdom and secretly laid plans, hoping to gather strength to protect the people of the world.
