As long as the special magical energy environment can be continuously maintained, the birth of magic power can be self-sustained and continuously produce magic power!
It defies the heavens even more than a true atomic reaction!
If really replaced, it would be like a perpetual motion machine that, once charged, could continuously release more electricity!
That is also technology passed down from the magic era, a breakthrough hope of a certain mage, but was later abandoned in favor of a power of faith disguised under the name "Thought Power" which seemed more promising.
To this day, no one has attempted to research in this direction, but simply uses it as a part of spells, providing a momentary surge of enormous magic power for spellcasting.
It eventually became a casting technique to increase spell power.
However, researching that will be something for later; right now, the most important thing is to deal with the enemy in front of us.
