Under Roy's wish to hear the details, Mephisto hesitated a little but still told him about the trouble he had encountered.
Mephisto, known as the King of Hatred, was recognized as a big boss-level demon in the Abyss, Heaven, and the human worlds. This was without a doubt. His resounding name spread across many worlds, and his dark believers were all over the Infinite Worlds.
Demon kings of this level could be said to be able to fight wherever they wanted and destroy wherever they wanted. It was difficult to find an opponent in the Infinite Worlds, but this did not seem to be the case.
As the saying went, if you walked by the river often, how could you not wet your shoes? If you walked too much at night, you would encounter ghosts… These words were probably used to describe Mephisto.
