What 稻 said above about world 7 ^. That place is a wreckage even for level90s so unfortunately you have a very long grind ahead of you before you even want to think about going there

I can't speak from experience because when my team was level40 I had many events to grind them on with minimal resource loss. What's said already is pretty good though I'd like to add that if you don't mind troop and resource loss then just go ahead and clear 5-4, you'll get the most exp from there for now + grinding for rare swords if you don't have them already.

As for KBC - I just trigger them anyway since imo they're not that bad so long as you have an evenly levelled team and the exp at boss node is like 3x what you get a regular node lol my citadel grew up with the kbc and we're now close buddies :D

Level40 will barely get you past some of the events if you want to grind for new swords and kiwame items (?) so if I were you I'd definitely grind up a 90s team that I can rely on during events and PvPs. Good luck :)
