Review Detail of DEvilLoynis in Reincarnated With The Strongest System

After 74 chapters I have to rate this book a 3.5. A few issues I have is that it took 70 chapters to get a monster rating system. Also we have no idea how the people other than mc level up or get stronger. Grandpa makes a big deal with him getting stronger killing monsters after all, which is odd. Little thing like leaving out what his level is as well. It's not clear if his main job lvl is his or not. Not sure why he has to go to Temple to advance main class but not sub. Little things like that constantly get annoying and only require a bit of early rewriting.
