Well I know it's stupid to write something like this, but I see the point of author. Real people when they're facing problems, they tend to blame others. It's normal for feeble mind people to think that way just to make themselves not taking any responsibility.
Now I only want to know how would...
finally someone pick this manga, I barely remember anything at this point.
But I smelled something's off, I think it's gonna be a point soon that I would want to drop this manga because of how bullshit the logic is.
The manga part is too short though. I hope anime version make it easier and progress toward the end in just one season because I couldn't see the part where it can pause. If it's anime I think they could shorten the growing part though I know novel readers like that part but it would be pretty...
IF the 1/1 is highest level mean he got highest growth rate, then if he train hard he'll be super strong in no time. But if he's stay weak forever then the only way would be items which very stupid. I'll read for a while to see what's gonna happen then.
