While Oliver was waiting outside, Leon walked into the test chamber. It was a large spherical room with a metallic stele at the center.
The SMB officers were standing behind a glass panel on the other side of the room, observing and giving directions to him.
"Walk forward and place your hand on top of the metal block in front of you." A voice spoke through the speakers attached to the wall of the room.
The room was designed that way to isolate the mana response from the individual. Other people within the room would have caused the measurement device, the stele at the center, to produce erroneous measurement.
Meanwhile, it also acted as a protective barrier that prevented SMB officers from being harmed by the weird and unpredictable abilities of the superhumans.
"Okay." Leon snapped out of surprise and walked towards the stele.
