There's a hidden quest

Slurp! To clear Chapter 2 in just 30 minutes while also doing exploration quests, your analytical skills are truly brilliant, hmph! Just like when you shared your legal knowledge last time, you've pointed out an efficient strategy, how merciful. I'll be watching to see you meticulously clear the remaining Chapter 3, hmm!

This dungeon had an error today... Since I've already installed it, I guess I'll just forget about the dungeon and try to play through it.

Whoa~ that's amazing! Wonder if I have one too? 😂

Am I the only one not getting the hidden item? ㅠㅠ
