If you're looking for Japanese isekai manga, I do have a list, but it's all mixed with action, slow-life etc.

If you want Korean isekai manhwa, I don't have a list yet for it, though there's a lot already existing if you wanna look for them.
As a general rule though, any isekai comics related to cooking or farming, they're mostly slow-life and relaxing, so I would recommend looking for those.

I was wondering why I stop reading this, other than to marinate this. Well, I know why now. This manhwa is exhausting. Oh, it's definitely a fun read, full of action. But it's precisely because it's full of action that it because exhausting to read. Not enough downtime to cool off from all those burning hot action scenes. I literally need to read a relaxing, slow-life peaceful manga to recover.
So yeah. Awesome manhwa, but also tiring to read. I'll come back in a bit after reading a slow-life isekai manga.
