Cen Yan, an ancient books researcher, was drawn into a world of dungeons driven by "The Classic of Mountains and Seas". Each dungeon corresponds to the natural rules of an ancient beast.
He must break the rules within a limited time to escape, and every time he uses a "word order" to rewrite the rules, he will lose a piece of memory.
When he traced his missing sister Cen Yu all the way, he discovered that "The Classic of Mountains and Seas" was not a book of myths, but a legacy of ancient wars. . .
