Review Detail of Laplaces_dream in The Honkai Revenant

I would have given it 5 stars alone because it is a Honkai Impact Fanfic. But the reason I didn't is because of World building. Now, for only 2 chapters it is natural that there wouldn't be any world building. But the thing is that for Fanfics world building is not required. But the problem is that I still cannot understand which world is this story taking place in. I mean there are elements like Honkai zombies, so you think that it is in the Honkai Impact world, but then there are also special skills, bear monsters, etc. and now I am thinking, is this taking place in Honkai world or a swords-and-magic world???
