1899 Temptations of a Devil God

Adrian did not just think of the devil summoning magic circle as he noticed a small fly that suddenly settled on his shoulder. The moment he was about to swat the fly was the moment his head was suddenly filled with a magic formula in the language of the devils. Adrian knew this language due to him collecting a tome in the secret vault of the Devil God Beelzebub.

If one were to ask if Adrian did sneakily take it, then yes, he did but he also knew that the Devil God Beelzebub noticed him. If the Devil God Beelzebub did not say anything about it, then he just took that as an approval. What Adrian did not know is that this also meant that the Devil God Beelzebub will have a sneak peek in his life but only in the mortal realm where the eyes of gods can see.
