Review Detail of Chibixx in Mushoku Tensei Arthur

I like volume 1. Now for volume 2, not so much. There is too many added oc characters into the story that I wish the author sticks more to the original storyline. For how story development is going, in my opinion very slow. Over 60 chapters in, we barely reach volume 2 of the original novel. Author adds too much stuffs that it delay the story development. Author needs to pick up the pace to the story like 10 chapters per volume. This fanfic is good but it's just go too SLOW***W. How can the fanfac be on volume 3, when the original novel is still at volume 2? That's is how you know, the story is so slow.
