At the end of the Northern Song Dynasty, a sudden change in the palace leaked information about the hidden location of the "Sheji Map" of the Northern Song royal family.
Legend has it that this "Sheji Map" contains the treasures of the emperors of the Central Plains and the secrets of the royal family of the Northern Song Dynasty. This has aroused the covetousness of people from various factions.
Prince Zhao Kai of the Northern Song Dynasty was ordered to protect the Sheji Tu when he came of age, and met Fang Baihua, the daughter of the leader of Manichaeism. After a series of difficult struggles, he uncovered foreign conspiracies, settled internal disputes, and gained love.
