Review Detail of Recklesspen in An Extra’s POV

Don't get me wrong, this is a great story, annoying as hell but great nonetheless. Author, I have some questions (1) why does the MC sometimes act like a regressor? (2) you keep referring to the MC's class as a commoner but he already has a class and no longer a commoner. (3) the MC was level 99 and he doubt he could defect a level 12 otherworlder necromancer why?
