The Barrier: Final Annihilation Method is considered to be a technique of last resort. By creating a barrier similar to the Four Corner Yang Formation using Yang Release, the user seals of a particular area of their choice, then by using their own body as a medium, they create black water from nothingness using Yin Release to form inside the barrier that will destroy any organic material inside the barrier's boundaries including the caster and whoever is trapped with them, with the water leaving nothing behind, not even bones. Materials made of metal or stone will not be destroyed.
