Webnovel are a little different than traditional novels (in my opinion)
I've seen MANY webnovels that are extremely long and readers seem to be perfectly happy with that. Of course, I imagine that the writer is keeping a good pace and continuing to move the story along.
It may also depend on how long each of those episodes are too. If they are on the shorter side, then it makes sense to have more episodes.
You would have to review the story to see if the pacing is too slow. If it is, then you may need to make some adjustments. I would focus on the content. If it's good, people probably won't mind that it's long.
