How does this have a 8+ rating?! This is such dogwater I almost drowned in my own puke trying to read it.
In all honesty, it's pretty bad, for a manga which is all about trade in another world, the mc doesn't know jack shit about it, makes such obvious stupid mistakes trade wise and the author doesn't punish him and at least makes him learn and grow in that way. Nope, just plot armor. Generic self insert,plot armor,self pleasing shit. Hard drop
