There are countless divine waters in the world, with varying ranks and levels, and perhaps only Joseph Gourd could fully articulate this.
The stone here is Divine Spirit Water, or more precisely, an "aggregate" of another form of Divine Spirit Water.
Most of the time, Divine Spirit Water exists in various aggregated forms. This water naturally aggregates various materials. Even the softest sand, when dripped with Divine Spirit Water, becomes as hard as steel. Just like this huge rock, when Ethereal Devin used an iron scoop to hit it, it only left a white mark.
Only on the night of a full moon, when it absorbs enough moonlight, will it completely extract and return to its liquid form.
But after the full moon, it still returns to the aggregated state.
This Divine Spirit Water is an excellent object for repairing damaged magical instruments, and after being further refined by Joseph Gourd, it can seal its opponents below the Fourth Great Realm in battles!
