Keepers of the Mountains and Seas

In ancient times, after Dayu controlled the floods, he ordered Boyi to compile the "Book of Mountains and Seas", which was actually a "book of alignment of heaven and earth" - the mountains, rivers, strange beasts, and secret realms recorded in the book are not fixed, but "dynamic records" that are constantly revised as the spiritual veins of heaven and earth flow. Every page hides the calibration code of "record" and "reality". There is a lineage of "scripture keepers" in the world, and their core mission is not to simply protect ancient books, but to use the codes in the books to correct "recording deviations" caused by disordered spiritual veins, so as to prevent the secret realm from overlapping and collapsing with the real world.
