In the gap between neon lights and steel bars, the century-old game between the "Ring of Apocalypse" and the "Shadow Organization" has never stopped. Elementalists are divided into five levels according to the number of elements they control. From the bronze level to control a single water ball, to the legendary level to manifest a rift in time and space, the evolution of each emblem is accompanied by tearing pain: Lin Yu's water pattern will eventually integrate fire, thunder, wind, earth, and metal, weaving a six-color scale on the wrist, becoming the key to balancing the world, or opening the lock cylinder of the abyss.
