Chapter 154 Eternal Life

Symbiotic Stones were a miraculous creation; they could replace failing parts of the human body, supply energy to the host, and extend their lifespan.

The principle of this energy supply was easy to understand. For instance, if a person had an incurable disease and their entire liver had necrotized, then the Symbiotic Stone could take the place of that person's liver, allowing the body to return to normal function.

However, this function was limited to internal organs of the body and did not include the completeness of the limbs.

Depending on the size of the stone and the extent of the host's missing bodily functions, the duration for which their energy would suffice also varied.

A complete Symbiotic Stone was a fully blue crystal. The one embedded in Corrigan's forehead had turned black, signifying that the power of the stone was nearly depleted.
