Although this world was a fantasy world, with elements like wizards and magic beasts, in the Wizard World, and indeed in most worlds, magic beasts typically didn't have things like demon cores or demon crystals.
And for those races that did have similar entities, their magic essence and demon cores were used as energy storage devices or as organs for attacking.
But the substance resembling an inner core that Richard now saw before him had nothing to do with either.
The Toad King's inner core, white as snow and about the size of a baby's head, had a calcified layer on its surface similar to limescale and weighed approximately five kilograms.
Furthermore, this inner core's shell had strong isolation capabilities, so much so that Richard's spiritual power couldn't probe its interior.
"This thing was left inside that toad's body, but don't underestimate it. When I found it, it was soaking in the toad's venom, yet it hadn't been corroded in the slightest."
