Nie Huaisang has perfected the art of fading into the background; even when he's calling attention to himself, it's in a way designed to distract from what he's actually trying to do. He knows what it will take, how long he'll have to live like this, and he doesn't mind, not if he can achieve his goals at the end of it.

He's a cultivator; he can live as long as he needs to - unnoticed, unremarkable, unseen - in order to get his revenge for his brother's murder... and he will.
