Nie Mingjue proceeds to yell at him for at least ten minutes straight about respect, appropriate behavior, and other things his actions in the past five minutes did not demonstrate. 

Meng Yao is having several emotions right now. The loudest is vindictive, vengeful glee.

The second loudest is Oh Fuck That's Hot.

He finally ends with "--and when Meng Yao says I said to do something, fucking do it!" 

Xue Yang can clap pretty well with his hands tied.

Aw, yessss, excuse to kick him in the balls!

"OWW. I was being POLITE -- ahhaa, hhahaha, ow. Bitch."

Lan Zhan wasn't looking for an excuse to kick him but she absolutely will.

Wow, fucking white knight over here. That's - pretty funny actually - Xue Yang starts giggling again, even as he's bent double in pain.

"Meng Yao can finish taking Xue Yang to the dungeons, now, Sect Leader. By your leave."

He nods firmly and respectfully to Meng Yao. 

He bows deeply back, appreciative and sincere.

Then he escorts Xue Yang away, feeling warm all over in a way that, shockingly, isn't rage.

"Wow," he whispers to Wei Ying.

"Is that impressive? Madam Yu would've slapped him instead of punching him but it's not that different..."

"Oh, it's not unusually impressive. It just always impresses me to see Da-ge yell at people who misbehave like that and make everyone fall in line so quickly... I really don't think I ever could! No, I know I couldn't."

"Ah, well, everyone's different! Can you imagine me yelling at someone like that without once slipping in a smart remark? Or Lan Zhan saying that many words in a row? Or...hm, Jiang Cheng could probably do it."

"...Thanks???"

He laughs. "Ah, Wei-guniang, you are so clever about these things! I think I'd like seeing you yell at someone like that someday, smart remarks and all."

"We should return to discussing the matter of Qishan Wen."

"Yeah...they're really being a pain right now, and no doubt. There are four pieces of Yin Iron in total, right, there's the one Lan Yi had, there's the one the Flower Lady had, and...hm. Do we know if the one Xue Yang had and the one Wen Chao had are the same?"

"I doubt Wen Chao trusted Xue Yang with his piece."

"Hmm, you're probably right. So all four have surfaced but one is still unaccounted for...by anyone but Xue Yang. And even if we manage to get that one's location out of him we'll still only have half of them..." sigh. "Wen Chao is such an assbucket. We're going to have to fight the Wens for their pieces at some point. That's not going to be fun. Maybe if we turned our piece into a weapon..."

"Wei Ying."

"What? It's not like they won't use theirs against us."
