There is no world map, so we don't have any idea where anything is located.

But it IS clear that the deepest part is in the core of the Demon Realm.

There are multiple Demon Realms all over the world, some big and some small.

If you mean the Royal Demon Realm where the DemonLord resides, probably at its core where the density of Demonic Energy in the air could monsterise a hero near-instantly.
