Damien spent a few more days in the cell before anyone came to get him, but that wasn't bad for him at all.
Rather than a burden, it was a benefit.
It was impossible for Damien to marvel at the Heavenly World itself. The world was just too big for him to even begin to understand its beauties with such a small stay here.
However, its mana was both beautiful and ever-present.
Its perfection was incredibly beneficial for him to study, because it was a force closer to existence than anything he'd seen in the lower universe.
On top of that, his mana was a unique energy that could transmute into anything. Learning the ins and outs of other energy forms would strengthen him greatly, and the moment he fully understood them and gained the ability to combine or dissect them with a thought, he would reach an entirely new level of power that nobody could touch upon.
It was interesting.
