Really?? You should travel more! People from Liyue are great! I would know, I'm one of them!

[He says it with a slight snort, giggling at his own joke.]

Wait, are you serious?? Mondstadt doesn't have exorcists? Then how do you handle your evil spirits?? Surely you don't sing songs and drink wine to banish them!

[Though, what a sight that would be! It would definitely be an odd exorcism if he came with ozmanthus wine and a dizi flute. People from Mondstadt sure are weird!]

[But when Diluc asks about his friend, Chongyun lights up like a lantern. In fact, a few more dreamotion lights light up around him as well.]

Yes, of course! Xingqiu is my close good friend! We've known each other for years, we're best friends! He's the second son of the Feiyun Commerce Guild, and he singlehandedly revived the lost martial arts of the Guhua Clan! He also gives me very reliable knowledge on where to find evil spirits. He's a very good friend! I don't know where I'd be without him. Look, he even made me this tassel, as a sign of his belief in my becoming an exorcist!

[And he's going to get all up in Diluc's personal space as he turns to show off the tassel on his hip, attached to his Vision.]
