“Hey,” Lao Nie protested mildly. “Who’s the father here, me or you?” “If a-die wants a new wife, little uncle will find one that isn’t inclined to kill him.” That sounded like a recitation. “Then what’s even the point,” Lao Nie grumbled, and reached out to ruffle his son’s hair, enjoying how Nie Mingjue yelped when he did, glaring up at him with offended dignity.

I entrust you with his care, for my sect cannot be trusted with it.”
