Kyon took the choice of enchantment seriously. He had enough resources to enchant a human soul up to the advanced grade. First, he needed to test the waters experimenting on a relatively cheap rat.
Lovr picked up the animal and cast the most promising enchantment of enhancing pure energy that required all the nine elements.
As expected, the new enchantment replaced the previous one. The effects didn't stack.
Kyon infused the rat with Synergy and forced it to release some pure energy to test the changes.
{Hm… How curious! The element has become two stages more powerful. It means it will be only eight stages more powerful after a master grade enchantment. Not too much.}
Any practitioner in the world would hit him in the head for this outrageous statement. Eight stages for the fundamental element with a single grade! Wasn't it a blessing from above? Pure energy could be used for both defense and attack! This arrogant bastard was a tad too presumptuous!
I've calculated the exact mass of the weapons in different arcs, including the final ones, and concluded that these numbers are so extreme they're virtually inconceivable. I will have to sacrifice "realism" in favor of beauty. You might want to consider it a beneficial convention.
