In the next few months, Emrys visited all the top forces of the world and personally killed many Supreme Cosmic Apprentices and Exalted Cosmic Apprentices, and many of them submitted to him early on to save their own lives.
He forced all the top forces to bow down to him and truly established his rule from then onward. Just like that, he became the ruler of the world.
However, the trial didn't end there which confused Emrys. After all, the trial was for him to become the ruler of this world, and he achieved exactly that feat. Generally speaking, the trial should have ended, but it didn't which in itself was a big question mark.
