Speedread up to chapter 208 by machine translation with minor edits after chapter 24.
I suppose those later chapters may be more enjoyable when a proper translation is out.
I liked the premise, protagonist being stuck in a gamified world, with a curious lack of obvious numbers to track progress.and many other stats being hidden to its inhabitants. The protagonist gets some advantages, namely cheat skills and insta-respec to potentially exploit all of them and extremely cautiously starts (ab)using them, problem is, he or the author hamstrings that progress progressively.
He can see empty skill slots on items, numeric levels on peoples' jobs and so on, but still has no hp/mp display for some reason.
At the beginning he gets a uber weapon by spending 63 of the 99 skill points he starts out with, notices he can respec and disintegrate the sword to get the points back to put them into better categories, like exp gain multipliers and magics and stats.
And here my headache starts, for whatever reason the author refuses to get rid of said sword to ie.: increase stats, use more jobs at once or anything really useful in favor of keeping "it" around, even after he can make weapons which would be an adequate replacement for the darned thing. Which becomes obvious at around chapter 60.
He is the only one which can safely create equipment with added effects, gets tons of gear which has 4+ skill slots in the early chapters, and even by chapter 208 has at most filled two slots on any given item, if even that.
In the draft released as chapter 9 where he hints at characters introduced a few dozen chapters later he has a "5x attack increase" slotted into a weapon, an old one. Guess what, he still hasn't made a weapon of that kind by chapter 208.
He is also constantly MP bound, expending it rapidly, but refuses to raise the stat or decrease the expenditure with appropriate skills he could make by the dozen well before getting his fourth party member.
MP in that world when nearing zero relate to a terribly depressed mindset, make of that what you will.
My issue, the progress of the story is hindered, as most chapters at 120+ are more or less battle or eating descriptions where the ever increasing party members each attack some demons, evade and so on, the exploitation of the worlds' system grind to a painstakingly detailed halt when he tests his latest theories and frets over whether his special nature can be discovered or not.
I'd have preferred much more progress, in lieu of that draft chapter.
The world also could have done without slavery, his bought party members really are nothing more than hired npcs to satisfy his needs. All fine if they weren't actual people.
At times this series can be intriguing but the lack of real story or progress later on just annoys me.
Would have rated this a ten for the bits of the premise I liked alone.
But I suspect the author wants to sell more volumes and has no idea how to fill those other than slowing progression down to a crawl, a pity.
