If there were elemental spirit stones, there would naturally be elemental spirit crystals.
Attribute Spirit Stones didn't have much use. They were much more helpful to attribute martial artists than ordinary Spirit Stones.
However, the cultivation of attributed martial artists could increase, but attributed spirit stones could not.
Once an attributed martial artist made a breakthrough, then whether it was ordinary spirit stones or attributed spirit stones, they would no longer be of any help to him.
If he wanted to cultivate, he had to use Spiritual Crystals.
However, Spiritual Crystals were the product of extremely dense Spiritual Stones.
Ordinary Spiritual Stones that were extremely dense could produce ordinary Spiritual Crystals. Attribute Spiritual Stones that were extremely dense could also produce Attribute Spiritual Crystals.
Attribute Spiritual Crystals were of equal help to Attribute Spiritual Stones to ordinary martial artists.
