On the execution ground, Lu Chong, who was studying the Classic of Mountains and Seas, was reborn as an unknown refugee, holding in his arms a cub that was judged by the church to be an evil spirit. There was no body left behind by the woman on the execution stake, but a line of ancient characters appeared in his palm on the broken slip: Spiritual Lord of Mountains and Seas.
He can correct the tampered text, but he cannot decide the fate of the alien beasts; every time he writes, he must exchange evidence, choice and price for an erased path.
The church wants to write alien beasts as evil spirits, the nobles want to turn them into prey, and the academy wants to dismantle their bloodlines. When Lu Shu leaves the first blue hoofprint in the Black Forest, Lu Chen must find the remaining pages of mountains and seas scattered across the Western Continent before all the names are rewritten.
And at the end of the broken page, buried is the truth that the two worlds have forgotten together.
