Fading Sect: Purged Heaven

Fading Sect: Purged Heaven also known as Chaos Dragon's Breath is a Hashū technique invented by Ryuuki. It is known to be Ryūjin Shinkō's counterpart. This is because just like Ryūjin Shinkō mimics the Tailed Beast Ball with water, Fading Sect: Purged Heaven mimics the famous tailed beast skill with Hashū.

Description
When Ryuuki uses this technique he takes advantage of his tremendous lung capacity by inhaling deeply. His inflated lungs are quickly filled to the brim with chaos energy in the same way fire chakra is gathered when he uses Fire Release: Great Fireball Technique. The amount of chaos energy in his lungs is still not enough so he compresses the chaos energy to its utmost limit to make room for him to gather even more chaos energy is his lungs. With a loud roar, Ryuuki decompresses the chaos energy resulting in a massive blast of chaos energy that spews from his mouth.

The power of the blast depends on what form Ryuuki is in. When he is in his tailed beast form, the blast is noticeably stronger. Powerful enough to eradicate an entire island, leaving a whole in the ocean where it once was. When used in his human form, Ryuuki is capable of leveling an entire forest.The blast can do a lot more than just hit its target with an absurd amount of blunt force. The pressure of the chaos energy allows it to harm opponents on a cellular level as well, damaging its targets chakra circulatory system to the point that it is almost unhealable. Occasionally, particles of chaos energy will seep into the opponent's chakra circulatory system to continually harm its victim even more until they are dead or it has been expelled from the body.
