Outside The Tower
William looked at the Artifact Spirit, who was still present in the room. He was thankful for the Spirit's assistance since without it he would probably have failed at the 101st floor against the Medusa, but its presence also meant that William couldn't safely upgrade any of his Talents.
He would have liked to upgrade some Talents before leaving, but it couldn't be helped.
"Senior, I'm going to exit the tower now, is that alright?"
"No need to ask me for permission. Just do whatever you please. By the way, there's no need to hide your Space or Time Magic, we already know..." the Artifact Spirit disappeared as he said the last few words, leaving William, Atticus, and Uri alone on the 200th floor.
They knew this whole time? Damnit, I hid myself for nothing! William complained inwardly, even though he had already suspected this.
He didn't think on it too much.
