Folklorist Gu Yan stepped into the mist-shrouded fishing village just to record the ancient "tide festival". When the villagers' lyrics resonated strangely with the fragments of "Mountains of Madness" he had collected, he realized that this was not superstition, but a survival code written by the ancestors with their lives. An "Animated" "Folklore Decoding Book", with tidal changes caused by misunderstandings time and time again, Gu Yan walked between fishing fires and ancient books, peeling away the fog of time, and finally condensed the shocking discoveries into a book, allowing the submerged wisdom to see the light of day, and guarding the light of reason hidden in ancient rituals.
