There are many hidden safes in Dying Light 2 Stay Human that reward the player with answers to some of the game's biggest secrets.
The Bazaar safe is at, of course, the Bazaar. Specifically, it is in Old Villedor at the top of the Church Tower. This is one of the safes you'll find later in the game and it requires a ton of stamina.

The poster has a skull on it and reads Rock Music Station. Interact with it and the code will be added to your Collectables inventory. You can then read a math problem, 5x100+15-5=, that will
