Legend has it that the map holds the treasures of emperors throughout the history of the Central Plains, along with secrets of the Northern Song royal house. As a result, it becomes the object of desire for people from every faction.

Through a series of arduous struggles, he uncovers a foreign conspiracy, puts an end to internal strife, and finds love along the way.
