"Although I don't feel very tired, I should head back to the gun store first," Zhang Yanhang thought. His supplies on hand weren't particularly plentiful, so this time, he planned to use the hundred slots of the storage box to completely empty the gun store. He had actually wanted to do this before, but the waist bag's slots were insufficient.
But now, with the storage box, things were different. With plenty of slots to spare, Zhang Yanhang only needed to stash all the firearms and ammo from the gun store into the storage box, and he would no longer need to waste time visiting the gun store in the future.

Fifteen minutes later, Zhang Yanhang had successfully returned to the gun store and had loaded all of the firearms and ammunition into the storage box.
