"Shhh..."
"From a brain computing capacity perspective, replacing mana with Free Energy Elements to perform casting spells will substantially increase the casting difficulty. It's like using First Circle Magic standards to release Zero-Circle Magic, or Second Circle Magic standards to release First Circle Magic, which feels like a losing proposition. However, this issue can also be resolved.
One solution is to release only those spells that are less powerful and have simple spell models, so the added difficulty is not too high and within an acceptable range.
Perhaps releasing less powerful spells will not be very effective in a battle, but what if not just one spell is cast, but ten, twenty, or even hundreds simultaneously?
In the present world, all magic requires the operation of mana.
