This figure that was as large as a mountain released waves of terrifying aura, causing the surrounding underworld monsters to shiver.
Just by looking at its size and aura, one could tell that it was a true demon King.
A monster at the level of a Demon King, the master of a domain in the netherworld, controlling a vast territory.
There were countless monsters in the underworld, and the Demon King never lacked cannon fodder. When they launched a war, their tactics were often simple and direct.
Drive the cannon fodder to launch a fierce attack, causing serious consumption of the target, and when the time is right, the Demon King will personally appear.
It was unknown how many enemies had been defeated by such a simple tactic and ended up as the monster slaves of the underworld.
Even if he was unwilling, he was powerless to change it.
The servant was in the depths of the soul and bound by the Mark of the Demon King, unable to escape.
