Outer Path — Samsara of Heavenly Life Technique (Earth-2356)

The Outer Path — Samsara of Heavenly Life Technique is a reincarnation Force technique used through the Outer Path, which can infuse new life into the bodies of the dead in exchange for the user's own life.

Usage
When this technique is activated, the King of Hell emerges from the ground and releases the souls of the deceased from its mouth. These souls may be recalled from even the crossroad between life and the afterlife, and are then returned to their rejuvenated bodies. The exact limitations of this technique are unknown, but on one occasion, it was able to resurrect a large number of individuals who had recently died. While using this technique, the caster is severely weakened; for instance, Nagato's hair turned white as a result of overexerting his power. Ultimately, once the technique is finished, the user invariably dies.

This technique can also be used to transform the corpse vessel of an individual revived by Summoning: Impure World Reincarnation into a real body of living flesh and blood.
