Slaughter City was created thousands of years ago by a person who had broken through the 100th rank. He created slaughter city in a way that even Title Douluos are unable to use their Spirit Abilities.
Slaughter City is governed by the Slaughter King and he has enforces even in the level of Title Douluo who have been granted the ability to freely use their Spirit Abilities despite the restriction of Slaughter City.
