What I remember is that the MC entered this "Dark" world after using some treasure cause he was deemed a threat(people wanted his treasures) by the "good sects". He's already been there for a while, I think I got to a part where he finally got back that crown thing the the -fruit picker demon person's master- owned and then killed the person who killed the fruit pickers master. I know this isn't very accurate but it's the best I can remember.
