When a bunch of adventurers go missing in a supposedly starter dungeon, a high-rank adventurer is sent in to investigate.

Well, it seems like the slimes who took the kingdom are all sentient, so… good end?

Assuming all those sentient slimes have an intact ego at least, you can say that this is barely an apocalypse. They're basically living in almost the same way as before, except they're slime.
Unless...

Counterpoint: it doesn't seem to be guaranteed that being turned into a slime will allow you to maintain your ego, so it's not gonna be a 1:1 conversion rate. And plus, the slimes are probably usurping whatever reigning authority there is in the region
