Illusionists were "fertilizing" the Holy Shell Eggs, and Ange was doing the same, except he fitted the Holy Armor onto an Elf Chariot.
"You really thought of fitting Holy Armor on a chariot, why don't you just fit it on the Conch Plane as well?" Negris complained, but couldn't help but admire this miraculous way of thinking.
Originally, Elf Chariots needed Void Chimeras to pull them. For the Void Tree, which owns all the resources of the Void, raising a few dozen Void Chimeras was an effortless task, used for pulling the chariots in peace and charging into battle in time of war.
But after Ange hatched one, he found he couldn't afford it.
Even if he cultivated the entire Master Plane with World Trees, he still couldn't afford several dozen Void Chimeras. They grew several dozen times larger than regular Chimeras when mature, but ate much more.
