Legion-1 ignored his sarcastic comment and continued, "Secondly, if you are truly Monarch High Heaven, you are supposed to be dead. So you shouldn't be here."
"Thirdly, we found out that you were replaced by someone or something dangerous who, for your information, is the creator of this world. So no, we don't want to have anything to do with you even if you are Monarch High Heaven."
He had stopped because the only people who should know about their last meeting are Legion, Monarch High Heaven, the entity who replaced Monarch High Heaven, or entities too powerful for them to sense, like the Will of the void universe.
If this god is any of the three, then he has no use hiding or pretending. They would truly know his identity.
The god smiled and said, "Don't be like that. I have a sweet deal for you. You will like it because you won't have to do anything in exchange for what I have for you. So you can be sure that I am not going to cheat you."
