Interference of Mount Koryū

Using Senjutsu chakra, Jurokuido, Keiku replicates the region around [Mount Koryū] to span the area for many miles. Due to his Senjutsu Chakra being tuned to the mountain, Keiku is immune to its chakra nullifying effects, allowing him to use chakra while the opponent can not.

Even though chakra is required to live, this technique makes it to were targets can survive without chakra.
