God the writing is so sloppy they are practically reconning recons. And also the random lore dump kinda felt like a chuunibyou dream considering we don't actually know that much about the world itself other than "it was a game, before the MC got isekai'ed into it"
The writers are also pulling things our of their asses by saying MC gets a pretty broken stun ability even though other than skill books there was no other ways of getting skills outside of your starting 2 bonus trees, should've mention that before hand so MC getting this broken stun ability is less of an ass pull. Also that shank is literally the perfect weapon for MC since it has a defense pentation passive because with it he can literally rush towards enemies, stun them with his ass pull skill, the British the hell out of his enemies with that shank and use disarm on top making it impossible to win against MC.
That clussy can being MC's party member also makes it literally impossible for him to have any financial issues, to the point MC could easily buy the skill book he wants in just a few days
Edit: I should've mention this way earlier in chapter 9 but the raid leader giving MC the drop and crystal would literally mean he risked his life only to get no money, what a literal dumb ass
