Nie Huaisang does not like wars. He has never been much of a man for glory or honor, and as far as he's concerned the Wen should stop killing people so he can go home and paint fans and play with his birds.
But no one consults Nie Huaisang about matters of geopolitics, and so here they are.
Nie Huaisang has devoted himself to the prospect of survival with a level of grim determination that would be surprising to anyone who had ever seen him wield a saber, go on a night-hunt, or indeed do much of anything that he doesn't want to do. He has faked innumerable undetectable maladies, arranged for himself to be assigned to guarding caravans on the safest routes, and initiated a dozen boys into the wonders of sexuality before leading them to the conclusion that if he, Nie Huaisang, went off to battle then he might die and they would never get a blowjob again.
Nie Huaisang is tired of this. It takes effort. Nie Huaisang has never before done anything requiring effort and it is just as awful as he always thought it would be.
Right now, Nie Huaisang has attached himself to Lan Xichen to fetch him tea and confidential documents. To Nie Huaisang's mind, this strategy has four fundamental merits:
1. The First Jade of Lan is one of the most talented cultivators in the world.
2. While this is the case, he is spending his time not in battles, which kill people, but doing paperwork, which has never been known to kill anyone.
3. He is a warm, generous, and patient man, unlike Nie Mingjue, who has a distressing tendency to yell about bravery and the duty of the Nie when he notices what Nie Huaisang is up to, or worse be calmly disappointed.
4. Lan Xichen is an absurdly, unreasonably beautiful man and Nie Huaisang is optimistic that he can add him as Boy Initiated Into The Wonders Of Sexuality #13, although the fact that he doesn't drink is a problem.
And so Nie Huaisang happens to be nearby when a hole spontaneously opens up under Lan Xichen. He is far away from the hole to begin with and running in the other direction, and then it literally warps into a sort of ellipse so that it catches him and he falls in.
This is very unreasonable.
