I've Been Killing Slimes for 300 Years and Maxed Out My Level, (Light Novel) Vol. 05

I've been killing slimes for 300 years-and now I'm finally visiting my first dungeon! I didn't really want to go at first, but after exploring uncharted ruins and collecting hidden treasure, I discovered that the whirlwind life of an adventurer...really isn't for me. Plus, between our big visit to Beelzebub's house and sending my daughters to school, things have gotten so busy, I've almost forgotten how to take it slow!
