Phoenix Rebirth Technique

A high-level medical technique which allows Ryun to fully activate his body's chakra pathway system without breaking the Eight Gates. Doing so allows him to more easily flow chakra to different parts of his body and heal himself, creating the illusion of constant regeneration. Using this technique, he subverts the need for the Eternal Mangekyō Sharingan by regenerating the cells in his eyes, restoring sight to his Mangekyō Sharingan even after it has been overused.

According to Ryun, this technique takes precise chakra control and massive volumes of chakra, as it consumes a large amount of chakra while active. In a major battle, in which Ryun needs to conserve his chakra, he is often forced to wait until after the battle to use this technique. If need be, he can also use this technique to heal other parts of his body if they are damaged; fixing broken limbs and even ruptured internal organs with ease, so long as he has enough chakra to preform the technique.

The technique also posses a risk to Ryun's lifespan, as. By speeding up this process to allow himself to heal, he actually shortens his lifespan by a small amount each time he uses the technique.
