Have you tried this "The Legendary Moonlight Sculptor" yet, the art might kinda seems like what people might not like at first but it will get better. But I think this is discontinued for I know, if u want to know the rest u can read the novel.
this one meets all your requirements I think

oh but it does have things like "invaders" which I'm sure you'd be familiar with , but the whole concept of it is and what it's based around is more different than all the reused stuff you've read
Thanks y'all (づ￣ ³￣)づ
Can you guys recommend me an action manhwa with a unique plot? All I see these days is dungeons and necromancers. I'm kinda tired of the same tropes being repeated over and over
