Review Detail of LUCKY1488 in I Created A Dungeon In A Cultivation World

I really enjoy this book I just got caught up but great story but a few issues I'm having with it how is he so broke and the side characters have so many soul coins when most of them have only had access to getting them for a month but they got more then the dungeon master he seemed to.be making more when he was in the 3 kingdoms but now that he's in a stronger place he can't even make 100k from his raids it's not adding up since he got 10000 from one peak qi gathering realm unless he's getting less cause he's stronger but that don't make sense either can someone explain pls
