In ancient times, the Moon Tribe guarded the Moonwheel Secret Realm, which maintained the balance of the three realms. The battle between the immortals and the Moon Tribe thirty thousand years ago led to the Moon Supreme being sealed away and Chidi's fall, after which the secret realm was closed. The last Moon Guardian still alive awakens and discovers that Tai Sui's demonic energy is seeping into the three realms through cracks in the seal, while the fated curse of the Goddess of Xishan threatens to unleash a new catastrophe. At this moment, undercurrents stir in Cangyan Sea, Yunmeng Marsh, and the Immortal Realm. Ancient formations have been lost, the Moon Tribe's secrets lie buried, and a covert struggle over the fate of the three realms quietly begins.
