In the process of searching for another group of spirit Pirates, the sludge monster finally reached level 50 and became an elite monster.
In a special world like the demonic realm, a monster with the strength of a Lord was considered to be the true ruling class.
If one reached the king level, they could be called a Demon King, the strongest existence in the demon world.

In fact, the monsters in the human world were nothing more than cannon fodder. Their mission was to create panic and chaos.
When the human world was in chaos and cracks appeared in the dimensional barrier, the monsters of the demonic world would take advantage of the opportunity to enter.
