Ok translation quality however the story is... Terrible. I have no clue how could this book possibly be so highly rated compared to the other books ranked in their 30s, it is beyond my comprehension, really.
I have some doubt that the MC was a transmigrator with a job prior coming to this world, he acts nothing like how an ***** should, he literally does ZERO planning on anything. You'll understand if you read how he uses the system he has, the most annoying to me is that he rarely does anything specific on his own but random stuff happens to him.
Plot... horrendous and super cliché, it is not even lazy writing at this point. It was SO cliché that you know he will be white knight-ed on every occasion possible; his "friends" only exists to be bullied and cry so it shows how RIGHTEOUS MC is. MC's plot armor is so THICK and comparable to [Monster Paradise] he'll basically never be threatened by anything etc.
Characters... Actually there are no characters besides MC; the MC himself already being an one dimensional character his side-kicks of a grandfather is already 0.5D and everybody else is 0.1D for they, in the event that something is happening exists to either be there to sneer at our 1D MC or repeat "This..." after each useless descriptive sentence in unison.
I think I've never read so many cliche at this point in just so few chapters. If [Monster Paradise] was my bottom book before, this book successfully replaced it being at the very bottom as, not only does it replicate clichés but RECYCLES THEM;
