The primary function of an ordinary Divine Soul Restoration Pill is to repair the essence of the Divine Soul and soul damage. However, the Flawless Divine Soul Restoration Pill not only has a stronger effect in this regard but can also restore some lost lifespan!

For cultivators, using secret techniques consumes both the essence of the Divine Soul and lifespan. Once the lifespan is exhausted, even immortals find it hard to save them, leading to a fate of death and the dissipation of the Dao.

In the mortal realm, there are many pills and Heavenly Materials and Earthly Treasures that can increase lifespan, and there are quite a few such treasures in the Spirit Realm as well. However, almost all lifespan-increasing pills can only be consumed once.

This is a rule of Heaven.
