The Earth Element

The Black Rock Prison Method was an earth-type King Grade Celestial Method. It contained the Gravitational Space Profundity that was the most important law of earth. The combination of Gravitational Space Profundity and the Earth Elemental Profundity would form an independent space made out of black rocks to imprison people. At the same time, the caster would be able to control the gravity through the Gravitational Space Profundity in the independent space.
