"The Demon Lords Descend"
After all, just like Queen Rachel, Atherton also left a little part of his wing near his back to make it easier when he wanted to re-cultivate his wings.
After the first wing was down in less than a second, the sword cut down once more and the second wing also fell.
The King didn't even flinch or blink an eye at the pain and immediately manipulated the blood he spilled after he pulled out his teeth to carry his broken wings to the center of the two magic circles in the air.
The two magic circles formed something like a huge, invisible pillar where people could appear inside the pillar.
The king's own blood carried the wings and threw the wings into the magic circle, instantly giving the last two sacrifices to summon the demons.
Atherton had the bloodline of the demon lord, so he didn't need to offer his soul for this sacrifice.
