Thanks for the chapter!
I'm surprised Al isn't wanted by the Kingdom and Empire for all his antics. Also, while there aren't corpses what does he do with victims? A good trap is one which activates, does its job, and resets on it's own without requiring supervision. So trap would be better if slime came out of something in pit or was already on the bottom, negative energy collected and stored automatically, and victim teleported out of dungeon. Although if doesn't kill intruders and ejects them they'll be able to tell other people about location and setup of dungeon which could create a large raid group to form and storm through dungeon. Guess will have to wait and see what happens to her along with other devilish plans Al has. Good Irene was with MC for her own reasons rather than Al sending her. Hopefully she'll learn to have a better sense of self value and how to defend herself as time passes. Be funny if sleeps with MC several times on own initiative but refuses Al coldly along with slaps or spells if he pushes too far.
