[TL: DR - Ning bought a map of the tunnels with all of his energy and is making his way to room 34 where Khrom is at.]
Ning found a few kidnapped people in the rooms between 30 and 33, as well as a few more people he had to kill. After saving the kidnapped people, he let them know which direction to go towards and he went towards room 34.
Room 34 was situated at the center of the tunnel system and had easy access in all directions. So, Ning had to be extremely careful to not let the bandits know he was there.
The lanterns along the walls flickered as Ning finally opened the door to room 34.
The man inside reacted swiftly and looked up. He was an old man with a rough beard and a very well-built body. He was quite dirty and looked like he hadn't taken a bath for days.
When he saw Ning with the bloody cloth, he quickly reacted and swiftly stored away all the money and other items he had in front of him.
