Base [4]

Damien's low-level Void Essence leaked from his body and surrounded that of the man in front of him. He had acted quick, as his prior experience had already told him what'd happen if he failed to devour a Nox on time.

Even the devil worshippers would turn into inky liquid when they died. Damien had already formulated a theory on the reason for this.

It was due to the unnatural mana within their bodies.

The Nox were a strange species. Although Damien had already qualified the mana they used as Death mana, it wasn't pure death mana. Or rather, it was a breed of death mana that was unnatural. 

But the Nox were born to handle such unnatural mana. As a trade-off, their intelligence was low like beasts and they lost the ability to use any other forms of mana.

It was the same concept of balance that the whole universe functioned on.
