The laughter makes Jiang Cheng's back get even straighter; he's never liked anyone laughing around him rather than with him, but the idea of Wei Wuxian laughing at him makes him feel sick. He wants to turn around and shout at him, but he bites his tongue. Literally.

There's one magic word that gets Jiang Cheng to calm down, though, and that's the mention of his nephew.

"Jin Ling was with you?!" Why would his nephew be with Wei Wuxian again? After all the things that had happened - he feels a sudden rush of anger and hurt.

"If you were less stupid you would know he isn't here already! I would've found him!"
