Theos walked through the halls of the Zero Class building of the Academy, and not just any Zero Class, but the Third Year Zero Class, the most powerful class in the entire Academy.
Seeing the various doors around him, Theos did not pass through any of them. This was because he had increased his physical abilities with negative mana, consequently, his senses were also improved.
Thanks to that, he could hear which room had or didn't have people in it.
Several minutes passed like this. Because of the sheer size of the building, it was no exaggeration to say that it could take a whole day to explore it. Therefore, Theos increased the speed of his search, being a crimson blur to anyone who had seen him.
*Clanch* *Clink*
Theos' senses detected the sound of metal clashing against metal. Moving closer to the door of the room emitting the sound, Theos was sure... There is only one person in there.
