"Bad news! It's a Corruption Ceremony! Stop him quickly!"
Seeing the black-red glow spreading around the Black Dragon, Yulster's expression changed instantly.
Sebastian's demeanor also became grave.
As an Elf who had lived for hundreds of years, he was not unfamiliar with the "Corruption Ceremony."
It was an evil Divine Art created by the Blood Demon Duke Yabaton, capable of assimilating those with gaps in their souls into His fanatical Believers.
Those assimilated would become Undead Creatures, stripped of all emotions, with nothing left in their hearts but fervor for the Blood Demon Duke.
Their strength, too, would be greatly increased due to the corruption and the fall...
However, such an evil ceremony was quite troublesome to carry out.
Especially for corrupting those powerful beings, which often required lengthy preparations and day after day of prayers to congeal the power of the Blood Demon Duke.
