Really making your case here, Zixun. (Life would be so much easier if it was Zixuan who was good at wards. ...actually no, but it would be a different class of difficult. Zixuan, at least, would not be doing this in public. He appreciates that Shanghai may want the distraction, but could they at least not drag Chang'an into it?)

"What a confident statement."

"You were the one who failed to specify a surname!"

"Because I had no clue of Hu Zixuan's existence."

"How is that my fault!"

He pinches the bridge of his nose. "It's not your fault, but I had no way of knowing what you were assuming, or that you had such a particular definition of incest? You are the one he knew there were two Zixuans, you could have asked!" (That is very much your fault.)

"Look, everyone agrees you shouldn't fuck your lover's cousin! I feel like this is very basic etiquette!"

"He has a point, I don't want to sleep with someone who's sleeping with Jiang Cheng."

"But you're not related."

"Thank God."

"He's still my shidi."

"We're all shidis. Doesn't that imply that if you're sleeping with one of us you shouldn't sleep with anyone of us?"

"- What does 'incest' mean?" Masozi asks Nie Huaisang, when he translates this to English. He's not familiar with the word in either language. 

"Yeah, but Jiang Cheng is my shidi shidi. You know."

"Right. I'm definitely not having sex with someone who's having sex with Wei Ying."

"See!"

"He might have diseases."

"Hey!"

Nie Huaisang processes that Masozi said something. "Incest is when you have sex with a family member."

It is so weird having a conversation where everything he says gets translated, and then creates a debate on the definition. ...Though he did walk into that one.

(And sleeping with two different cousins might be playing with fire, but that is why he asked.) "What etiquette text did you get that one out of, Zixun?"

"The Book of Is There Literally One Hole, Just One, In Which You Have Not Stuck Your Dick, Jing Yi."

"Well, I think we have established I'm not sleeping with Hu Zixuan."

"....Huh. Is doing that bad?" It certainly seems mysterious and inexplicable that someone would want to, but honestly that's already true of sex in general, for Masozi. 

"That's a complicated question."

"You watch too much porn."

"If you have a baby with someone closely genetically related to you then they're more likely to get a genetic disease? If it's gay it's fine, just like sex in the Scholomance, but unlike sex in the Scholomance most people think it's really gross and don't want to do it."
