Did he push the million year button
Significant downshift in writing & art quality after a bit. I suggest [Arifureta] instead. Same core premise, better quality across the board, and its main narrative is completed and available. This just isn’t really worth more than a passing glance.
To be honest, I’m surprised someone bithered to TL this manga up to ch24. It wad never amazing, but after the art switch, they just straight up changed the story and the tone. It went from 5/10 but unique, to 3/10 and highly generic power fantasy slop.
The art in this for the first 9 chapters is incredible. Possibly some of the most beautiful I’ve seen in a while. But the story is mediocre and becomes less interesting after chapter 9. And the artist changes. It’s very sad.
Ermm 100k years? the tittle itself dont inspire me to read it
slow ass manga dirt poor author with some dick ass publisher co
Don’t let the start fool you, it becomes absolute garbage after
The dungeon arc is good
I think the artist saw the story just devolve back into another mediocre copy paste isekai and he chose to keep his dignity and walk away from the adaptation. Hence the publisher had to find another manga artist to take over and here we are.
dropping it, art is gone and story is going way too fast🙁
how can art change this much, until ch9.5 was really good, then it becomes too bad😑
It has potential but it simply does not enter through my eyes. I don’t like the artistic style.
I leave it here.
It was good reading until chapter 4 but I can’t keep seeing it, it makes me feel weird
It’s like it will suffice(do).
it’s pretty boring at the start but until he discovered the dungeon it’s starting to getting interesting but the art needs some improvement.




































odd premise but a typical OP MC tale. Tbqh the art improved after chapter 9.5 rather than the other way around, some of the monster scenes prior to that were unintelligible with all the heavy black ink.
