Unlike the open storefronts of the Free Trade Zone, the Arms Preparation Area located three levels underground didn't have any 'shop fronts' but was a row of warehouses sealed by steel doors.
In front of each warehouse with different signage, there was a Water Mirror screen, with several attendants responsible for making introductions.
If customers wanted to make a purchase, they would click on the desired weapons on the screen to pay, and once in the safety area, puppets would deliver the purchased arms.
Upon close observation, one could notice that at each warehouse door there was a pale golden talisman prohibition, which looked quite dangerous; even the Sword Spirit advised not to get too close.
