ideas for riders to write

I never really understand what not many riders don't make the character wipe their own conservation like I understand it be but I don't understand in the world of conservation this is so affectionate I mean for crying out loud the closest thing to Korean conservation is that The copier from the previous ones so maybe like I don't know a system that can help the main character to create cultivation but have a restriction of sort like for example gold for example like the more powerful useful or anything that sort the higher the gold needed for example of course so I don't know go a concept like that please
