In the next day,
Mack woke up, still feeling a bit dizzy, opened his eyes and stood up. Walked to the bathroom of the room, took a shower and cleaned himself, and when leaving the bathroom, he saw an old man waiting for him.
"Geez, you scared the shit out of me."
Said Mack, caught unprepared for that bald head.
[Stop joking, today is the first day of your training, get dressed and we will leave]
"Ok Ok"
Said Mack, already grabbing his clothes by the side of the bed.
The girl had left a long time ago.
Seeing Mack dressed, with his backpack, and the two swords, the old opened the door.
"By the way.... How did you get in?"
Asked Mack, not sure how this old man entered his locked room.
He was sure he locked the door after the girl left.
