The huge treasure vault was blasted open, and neatly arranged demonic crystals could be seen everywhere. They were piled up like a small mountain.
These demonic crystals were a type of heavenly resource unique to the Demon Realm, something similar to the spirit stones of the Central Plains.
However, spirit stones were formed by absorbing the spirit energy of heaven and earth, while demonic crystals were treasures formed by absorbing the demonic energy of the Demon Realm.
They both contained enormous energy, but the energy inside was completely different.
If it was someone else, they wouldn't be interested even if they saw the demonic crystals, because they couldn't use them at all.
This was the same as how the demons of the Demon Realm could not directly use the spirit energy between heaven and earth. They had to transform heaven and earth into an environment suitable for the production of demonic energy.
