Yea I've started feeling the same. The manga started out as "I'm pretty strong, so I'll start adventuring", then slowly started switching over to "I'm a noble and will slowly develop my land by being passive and having everything handed to me on a silver platter."
Like even that town he simply just...acquired. Sure he probably paid for it, but how "convenient" it is that there's just an entire empty town he can purchase. Everything readily built already. And then with some bullshit "magic" he teleports it all to where he wants it. No effort, no thinking. Just "here's a readily made town, and poof it's now where I want it to be".
And so many isekai manga do this. They start out with at least a half-interesting premise, but then devolve into "slice of life, but it's a medieval fantasy setting and the MC is a blank slate."
But even then, I’m fine with slice of life in the mc is actually living up to his expectations, not just passively going about everything with the golden finger of “coincidence” and people feeding him ideas or saving them every other chapter. I really want a good Isekai that’s unique or at least one that’s not the same plot rewritten
Maybe you're already reading these, but some suggestions:
-Otherworldly Sword King's Survival Records
-The Dark Magician Transmigrates After 66666 Years
-The world after the fall
-Infinite Mage (not really an isekai, but still fantasy with magic and battles)
-Tensei Shitara dai Nana Ouji dattanode, Kimamani Majutsu o Kiwamemasu (warning; the author was probably a shota writer before this, but the manga is actually pretty damn good.)
-Legend (takano Masaharu)
-Saving 80,000 Gold Coins in the Different World for My Old Age
-The Diary of a Middle-Aged Teacher's Carefree Life in Another World
-Tensei Shitara Ken Deshita
Thank you!
I’ll be honest, i started reading this cause the adventure was fund. However it suddenly became more of a “daily life of a noble” than adventuring. and then, even then he barely does anything. idk if he’s an idiot or just incredibly indifferent and nonchalant to everything but any problem that crops up he’s pretty much spoon fed the solution by everyone around him while he goes “hmm
