Review Detail of 3rdFattyWiggles in Reborn as a Indominus-Rex

The writer barely puts any effort into the story. The leveling system makes no sense. The MC kills a creature of the same lv as himself and gets 10 levels out of it? makes not sense. He could have just stated that his species gets a massive exp multiplier and I would have been satisfied but the author doesn't. MC has no caution towards his hostile surroundings even when he cold get casually rekt by a high level creature or humanoid. The only remaindering quality of is that the MC fights like a "CLEVER GIRL" but that part of the story is typically never as indepth as i would have liked.
