This story feels like it had some potential but it probably wasn't meant to be.
The MC's personality and behavior is really childish and immature, the author already forgot to give him rewards for completing a mission, the translation quality and editing is pretty bad and it eventually get's tiring to read.
Also the way that stats, leveling and skills are made really in depth will in most stories become too much and overly complicated where it gets hard to keep up with, both for the readers and the author. If you can do it well enough then it's good, but otherwise not so much.
