After Yang Ling tamed the Burning Fire Elf King successfully, he didn't stop. He continued using Earth Evasion Spell to teleport around, and he tamed the heavily injured Burning Fire Elves.
In the eyes of the mercenaries and adventurers, the top-grade Fire Crystals that the Burning Fire Elves would turn into after their death were too precious. But in Yang Ling's eyes, the Burning Fire Elves' value couldn't be measured by Crystal Coins.
As long as he tamed a team of Burning Fire Elves, he would be able to form a team of Spellcasters that would provide the Magical Beast Army's great magic support.
A centipede could wiggle even after its death!
After the Burning Fire Elves lost the Burning Fire Restriction and the Smelting Pond, their power dropped drastically, and they were uttered defeated by the humans' allied armies. But their fighting prowess was still no small matter because they were inborn Fire Spellcasters.
