In order to absorb this Eternal Frost Crystal, Roy first thought of devouring and digesting it directly.
However, ignoring how to swallow a sword into his stomach, after studying it, Roy found that he could not digest this thing because it could not melt at all.
It would be troublesome if he could not digest such a large piece of ice and freeze his stomach instead…
As for transforming the shape of the Eternal Frost Crystal and then using it to make items such as rings or embedding it into the Cold Winter Armor, Roy thought about it, but he later gave up on this idea.
