wow it took 11 chapters for the MC to stop being useless and for his ancestors to stop being a burden? I almost dropped this shitpile. Let's see if it redeems itself.
It is so infuriating to see the MC live as a slime. As I understand it, they're always nagging away as voices in his head. He could tell the old assholes to shut the fuck up. Or ask around for a way to get the curse removed. You know, getting rid of the useless junk draining your mana away. But no, it's just bullshit nagging chapter after chapter.
I mean, the dude is far from being useless. The only reason he's been seen as lacking is because of the jewel eating away at his mana. If it weren't for it, he would have been fine.
