In the hallway, Henry swung his head left and right. There were so many open doors to choose from. Subtle pulses of mana circulated everywhere as magic circuits littered the doors, frames, and walls.
The petty man walked past them and entered a room.
Henry turned to Felicia and casually waved his hand.
"See you later."
Henry entered the nearest room. All of the rooms appeared to be the same. There was no use for him to try to outsmart whoever made this library. His class was too low to succeed in doing that.

Henry hadn't held the door handle, but it closed as soon as he was in. A mana crystal glowed at the ceiling of the room. It was much shorter and reachable compared to outside.
There was a table there. A book lay open under the light.
Henry walked towards it. A question was asked on its surface.
"What is mana?"
