Yin-Yang Release: Chakra Regeneration Technique

This technique is a Dōjutsu accessible to the Rinnegan, noted to be the pinnacle of Medical Ninjutsu.

Usage
The user focuses eyes on a damaged or destroyed area, slowly forming the chakra into the destroyed or damaged or removed area, harnessing the spiritual energy which creates form out of nothingness, using the chakra as a medium, imagines that body area in its original state, using chakra in order to turn this thought to reality. The user then uses the physical energy to breathe life into the new area of the body, making it as good as new. Though this process is extremely difficult, Heiwa has mastered it to the point where he can perform it in under five seconds. This process can be applied on other people as well.

This technique, though a derived technique from the sage's itself, does cost a lot of chakra, but only according to the amount of damage to be healed.
