Based on the mythical creatures and characters in "The Classic of Mountains and Seas", a "mythical world" setting is constructed. At the beginning of the story, the protagonist accidentally discovered a fragment of an ancient "Book of Mountains and Seas". When he flipped through it, he was sucked into the world of the book and became a "visitor from another world" who could communicate with mythical creatures. His arrival broke the balance of the mythical world and triggered a series of chain reactions.
