The pacing is reeaaaaly weird. The mc waits years to be an adventurer, and it's just one chapter. Also, he keeps leveling up for nothing, his levels don't mean anything before he gets to meet the evil god. MC defeated the knight commander with a wooden sword, but struggles against the inspector of the magic academy ? The harem part isn't omnipresent, but still very annoying. I'm not a fan of summons either.
Still, it's not good, but not trash either, worth it a read if you have some spare time.
