And here I thought it could be something interesting from the flashback, with the guy getting banned for being perceived to be useless, BUT IF HE CAN DO AND CREATE ANYTHING HE WANTS WITH SAND, THEN WHAT'S THE POINT OF THE STORY!?
I wanted to see some smart uses of sand, like heating it up to create glass and make money that way, or maybe even use his "sand sense" ability to avoid monsters and detect food sources, but the guy just makes his own castle complete with complex decorations, furniture and a bed with no effort, and then DESERT ANTS GIVE HIM HONEY!!!!
Come on, this is worse than isekai slop!
