Review Detail of SuperMod in Astral Pet Store

There is no plot, the mc is ridiculously op, sits in his shop getting more op, and occasionally kills arrogant young masters, their entire clans, their neighbours, the dogs, cats and even goldfish. there is no worldbuilding or character development, and the story goes nowhere. the supporting cast are cardboard cutouts. I wouldnt bother wasting time. I read the raws up to about c400
