What to Do in the Dungeon?

Hello sir (handshake), is there anything we can help you with? Don't be afraid of what I'm about to say. We are Mithril level, we will not be afraid. Please tell me. I just had my neck broken by a peanut! Who is Peanut? No one, it's a peanut-shaped stone! What are you laughing at? I remember happy things. What happy thing? My wife gave birth to a baby. Why are you laughing again? Well... My wife also gave birth. Are your wives the same person? Right... No, they gave birth to children on the same day. I repeat it again! I'm not kidding! Right... Let's get down to business. That... The peanut you just mentioned, is it powerful? It's not a matter of whether she is strong or not! She is really that kind of... Rare kind... Her speed is sometimes so fast that she cannot see clearly, her body is extremely hard, and her strength is like that of a dragon, very powerful. Unfortunately, it was too dark that day and I couldn't see its face clearly... You bully others too much, I have tolerated you for a long time! My wife gave birth to a baby. You were obviously laughing at me, but you never stopped! Sir, we are strictly trained not to laugh no matter how funny it is... Unless we can't help it. It's better than this, sir, you go back and wait for news. We will notify you as soon as there is any progress.
