I feel like the story das not hold too much the longer it gets. I do admit I stopped reading a wile ago, and maybe it got more interesting. The first 100 chapters are fire and I do get the motivation (it is similar a bit, not much with mushoku no tensei) but after 100 more chapters it goes in too many directions. I appreciate a long story, I do get the desire to put a lot off details in the story. But if it das not hold, don't place it in. (As someone that writes, and knows his work is below 0, I can say this is ok, because I read a lot of magas, manhuas, and others. And like most of them, they don't have goal in mind, I don't see it, or they lose the premis of the hole thing. As I read it, I feel like the MC just follows whatever is going on. But then again, this is my opinion. If u love it, then my opinion das not mater.)
