In the vast East China Sea, there is an abyss named Guixu, where many waters gather and all souls end.
Lin Mu, an amnesiac boy, woke up from the cold sea water with nothing but a black scale with a mysterious vertical pupil engraved close to his chest. He was rescued by fishermen on a small island in the East China Sea, but he didn't know that he had become the center of attention.
In the depths of the ancient ocean abyss, the imprisoned dragon god "Chiyuan" screamed sadly, calling for the owner of the scales; the sea-robbers "Sea Wolf Gang" and the mysterious land-based "Abyss Seekers" heard the wind and vowed to seize the key to the ruins; and under the peaceful mirage island, the secret passages left by the ancestors were revealed to the light because of the scales, pointing to the bottomless abyss at the end of the mist.
As memory fragments emerged, Lin Mu discovered that he had a bond with Chi Yuan that transcended reincarnation. The scales are both the source of power and the shackles of fate, and they also lead him towards the all-devouring graveyard of time - Guixu.
