Kapitel 509: 501

The volume of this inner core was quite large; using it to refine elixirs to enhance one's own cultivation or to feed insect pets was a good choice.

There is actually a significant difference between the inner cores of demon beasts and demon insects.

If intended for human consumption, neither type of demon core could be swallowed directly; one needed to find a Pill Alchemist to refine them into elixirs before they could be taken. The failure rate of refining any demon core into an elixir was considerably high.

Even for Master Zi Zhou, the highest skilled alchemist in Miaodan Pavilion, the success rate of refining a Demonic Beast Inner Alchemy Elixir was only around 30%.
