I Became a Fake System

There are various systems in the City of Ten Thousand Realms System. The killing system wants to kill me, the devouring system wants to eat me. The show-off system wants me to be its younger brother, and the team-fighting system wants me to kill someone. The good guy system wants me to be a bad guy, and the hero system wants me to be a devil. I'm sorry, I want to live well, so I can only ask you to die! I am a fake system, and I am determined to become the master of the system! PS: The introduction is a bit serious, but it is actually a relaxed introduction.
