Casey Cao seems to be murmuring something. Go ask her what's going on.
Casey Cao: Snow beast spirit... It's the snow beast spirit... I must worship the snow beast before it's too late.
Casey Cao: I don't want to die here... I want to live to a hundred years old!
You: Ms. Cao, you said "worship the snow beast" just now...?
At the mention of the snow beast, Casey Cao throws you a malicious look.
Casey Cao: You city girls don't think the snow beast is some sort of adorable animal, right?
Casey Cao: This isn't a children playhouse...
You: (Ms. Cao seems to believe in the snow beast legends. Let's play along.)
You: I just want to help. We might be able to leave the mountain if the snow beast is appeased...
Casey Cao's attitude softens when you mention leaving the mountain...
Casey Cao: Help? Perfect timing, I have something you can do.
Casey Cao: We better hurry. I just remembered what the first step was...
You: (She just remembered?)
Casey Cao: When the snow beast first met Lady Qingnu, she fed it some snow water, which the snow beast liked very much.
Casey Cao: So our first step is to get some clean snow water as an offering to the snow beast.
You: Clean snow water?
Casey Cao: Yes, yes, get to it! It must be clean!
You: Okay... I'm on it.
