Jeff's oxygen cylinder

Director of Ordnance Jeff was the solid backing of everyone in the fire station. He carried a thick equipment bag full of gear and emergency sets that can be easily replaced. Jeff obtained this oxygen cylinder when he first became a fire fighter. He asked many retirees to sign on it and felt much honored as if he was fighting side by side with the seniors... However, the last signature on it was the Mechanical Hound's teeth mark. If you are in possession of this item, give it to Belm at the entrance to the Underground Laboratory 1F (Adventurers at Lv. 121 or higher may go and exchange) Obtain by killing the Removal Director of Ordnance Jeff.
