I read the whole series in an hour. I was expecting another typical mid series of an MC who uses everything, but it's slightly better than the usual. Not just the MC, but the side characters (excluding the original party) are quite intelligent. The system/functionality of Guilds is explained at outstanding levels even those new to manga can become experts after a few chapters. As mentioned, the MC is terribly OP at basically everything as it conjures his own techniques/spells/formulas unique to his use alone. Cool yeah, well not entirely. Power scaling is a bad problem in this manga, even at the latest chapter, it's not possible to understandhow the MC obtained or utilizes such OP stuff. Sure he looks and becomes strong, but there are too many questions pointing at "how" did he become like this.
