On the edge of the fantasy continent, there is a cursed sea area, and the Misty Island is suspended in the center of this sea area. According to legend, in ancient times, a powerful evil spirit was sealed here, and his resentment turned into a fog that lingers all year round. Every thousand years, when the last ray of dusk forms a specific angle with the seven mysterious spiers on the island, the seal will loosen, the power of evil spirits will leak out, and the terrifying creatures and strange phenomena on the island will intensify. At the same time, the Misty Island hides a mysterious treasure that can control the cycle of life and death, attracting countless spiritual practitioners to come to explore regardless of danger, but most of them never return.
