Singularity
"The fourth matter is related to your existence as the Singularity. Now that you have reached this level, you are subjected to the world's stability. You can exert your power and all kinds of power in the world, but as a result, if anything happens, I'll be the one to deal with you directly. You might be able to exert your trick, but in the end, I'm still the one holding your power."
After hearing about the situation, Theo didn't feel anything wrong with it. Since his power had surpassed anyone's, even if he were to be besieged by a lot of Saints, he could still do something about it. That was why the world would have priority over him in controlling his power since the world was the one who gave it to him in the first place.
"Alright. I understand the fourth one." Theo nodded with a serious expression.
"Last but not least, it's a matter of the agreement between us."
