The manhwa was quite good. Although if you have read a lot of similar series, I'd guess it wouldn't impress much.

This hasn't got anything to do with xianxia/cultivation. I don't know why Ryll would throw those words randomly around here. Korea has its own martial arts series (murim stories), but this isn't one of them, not matter how you look at it. This is more like a weird isekai story happening right on Earth.
