"The Book of Mountains and Seas" is not simply a geographical annals, but a fragment of the "authority genealogy", recording the "true names" and "attribution of authority" of all things. If anything has a name, its principles can be summoned; if it loses its name, its principles are scattered. After the "Disaster of Overturning Seal Script" in ancient times, the true names were scattered, the contracts of the gods were broken, and the world of Jiuye was shattered.
