So I'm a Spider, So What?, Vol. 4 (manga)

There's never a dull moment in this labyrinth, as that damn dragon is back again!! It's still too high level for me, so I guess it's time to escape while I can...Why does it always seem like, as soon as I get the hang of things, either I get knocked into a new (MUCH HARDER!) area or some other Big Boss comes outta the shadows to make me fear for my life all over again? I just want to know what I'm doing for once...
