Web novel is ok. There's ton of filler food chapters early on that drag down the whole plot. There were cut from the Light novel to give you a clue about them. The novel is by far best when the author is combining the scifi and fantasy elements, but his character interactions feel very one sided. Alan doesn't really show signs of development as of yet, but we're only 70 translated chapters in. All in all, I don't recommend the novels over the manga here, as the manga cuts a lot of the slack, and quickens a lot of slower parts.
