In the continent called "Iseland", the four major races (humans, elves, dwarves, orcs) once had a tragic war over the ancient artifact "Eye of Creation". After the artifact was shattered, seven fragments were scattered, each of which was sealed by the guardians of each race. Three hundred years later, Mordred, the leader of the dark forces, was resurrected through "blood magic" and tried to collect the fragments to rebuild the artifact and rule the world. In this turbulent era, an ordinary boy named Zhou Hang (Sabe) accidentally awakens the rare "Elemental Resonance" physique and becomes the only magician who can control the four elements at the same time.
