This is the level of OP tedium that most isekai fantasy series can only dream of attaining. Funnily enough most of them tend to have some loose sort of plot along the way.
This is about the level of Re:Monster though, in that all that ever happens is the protagonist just gets stronger and stronger and savages more and more opponents easily... with the bonus feature that any remotely interesting character gets removed from the "story" periodically to keep the focus on the boring-as-fuck protag. Like it is actually teasing that something interesting might happen, then suddenly "TOO BAD, TEDIUM-TIME!"... There genuinely is no plot. Just a dull bastard going "I'm gonna learn this skill"-timeskip-"I mastered this skill".
I think I'm actually in danger of falling asleep from the boredom.
