Too many glaring issues to enjoy this
-all powerful sword knows every single god damn thing about itself and the MC's 100% unique skill
-ability to sacrifice stats with no knowledge of basic math to save some stats (spends 30% at once instead of 10% then 10% then 10%)
-author doesn't know how time works, MC is assumedly 16 maybe 17 at the most has a 5 year old flashback of "friend" about 11/12ish with full head of hair, present day he has a receding hairline and a 5 year old kid
-stats mean nothing, a basic goblin has 1/10th the stats of an enemy that is maybe 3x as strong
-MC is trying to hide identify by use of a mask but doesn't wear it while wearing the same unique armor while traveling with merchants that could easily blow his cover
-unique skill needs to advance by staying on the cusp of starvation which instead of being like a day or a few hours is less than an hour and immediately thrown out the window when a big catch arrives
-MC is just fucking boring.
