The God of Void started explaining the possibilities of the creator of this world being alive to the real Lucifer. Considering this world used to be a B-grade star before it broke apart, their connection and knowledge about the upper realm are insufficient. Thus, it wasn't a surprise that the aborigines of this world would know about things beyond their realm. They weren't a S-grade world that had a direct connection with the upper realm.
As expected, the King of Hell was surprised with what he just heard and even asked, "Is... is this true? Does that mean my creator and my twin brother are still alive?!"
"What I said about your dad is a possibility as for you twin brother... if the one in Michael's body is like me, your brother had gone straight to reincarnation or remained in his body asleep as a soul."
