The Four Evil Gods Sects are searching for the source of Purification Crystals, and so is the Alliance.
The reason the Four Evil Gods Sects, whose high-level combat strength is weaker than the Alliance's, can hold their ground against the Alliance is due to the pollution of the Evil God's forces, making it difficult to fight them.
If the Alliance masters the method to produce Purification Crystals, the threat of the Four Evil Gods Sects will be greatly reduced.
Thus, both sides are trying their utmost to find it.
However, what they don't know is that the method to produce Purification Crystals cannot be replicated.
This is a unique and unparalleled skill, exclusive to Li Cunxu's Pure Crystal Dragon, even if there were a second Pure Crystal Dragon in the world, it couldn't grasp it.
The Four Evil Gods Sects and the Alliance are doomed to be futile; they will never find it.
