The voice fell silent for a moment, but Mephisto could still feel a certain gaze focusing on him. Shortly after, the air vibrated slightly, and that voice, as if emanating from the world itself, once again rang beside him.
"You're right, the one who truly makes the decisions is still me, and this is already the most likely method to succeed,"
"You've done well, and if all goes smoothly, after this battle, you will truly become the lord of the second layer of Hell. As for the matters in the Mortal Realm, if you can handle them well, I have another reward for you."
The voice had calmed down, and the odd feeling in the words earlier seemed like an illusion. That's right... A slight loss for a World Lord was not something to be overly concerned about.
If another method were used, either the risk would be greater, or it would ultimately cause severe damage to the Origin of the Nine Hells. If this move isn't effective, then we'll cross that bridge when we come to it.
