Is more than the series is following a pretty defined structure:
Plot related arc->filler/breath chapters->repeat
Certainly not the most optimal way to handle a story but somewhat expected. The author is fond of having polls on his website to allow the fanbase to pick what monster girl is gonna be introduced next. This usually leads to good moments where more world building is don but in others the attempt falls a little flat.
The recent farm chapter is the by far the lowest point with the fanservice being even more prominent than the usual and having some developments that contradict the rule sof the setting. Luckily, the next arc is focused on Mero and shows a lot of promise.
