There is something wrong with how Nie Huaisang's body collects mana. He's magical-- the mals that have haunted him since he was a child are proof enough of that-- but he can do pushups for ten hours straight and get barely enough mana to light a bulb. He can draw on the other enclavers, sort of, but any spell he casts takes ten times as much mana if he's lucky.
Nie Huaisang doesn't want to die.
It has been the primary goal of Nie Huaisang's life ever since he understood what a mal was not to die.
It would be one thing if he had the sort of personality that kept you alive in the Scholomance. But he's frustrated by tedious tasks, he breaks into tears when he's overwhelmed, and he gets overwhelmed easily and often; he can't handle stress or conflict or high-stakes decisions.
He leans into it a bit, once he figures out how hard it's going to be for him not to die. Safer to be underestimated. Safer for people to believe that not being the sort of person who will be able to survive is a choice.
(He's good at art. He likes art. In another world, he was born without magic, and he paints. But that's not the world he's in.)
When he was a child, he had his da-ge*, his brilliant badass da-ge, who spoke a dozen languages and fought like he was dancing and like he breathed, who loved him and was frustrated by him in equal measure, and da-ge killed the monsters under the bed that were a metaphor for every child other than him. And then when he was twelve, da-ge went off to school, and Nie Huaisang had to take care of himself.
Da-ge was going to take care of him again, now. He had two years of da-ge keeping him safe before he had to find another protector. Simple enough.
Nie Huaisang ran sprints every single day; he had three very good pairs of running shoes in his pack. He trained himself, constantly, in situational awareness, so that it was second nature to check every room he entered for mals. (It made people think he was just paranoid. Safer, to be thought paranoid.) He had a first-aid kit; he wounded himself, carefully causing pain but not damage, so he could practice doing up his wounds while in too much pain to think. He needed tradable goods to keep himself safe, and he thought carefully about what would be valuable that the adults wouldn't have thought of. So he taught himself to brew prison moonshine and to write quite good pornography. He made Wei Wuxian carry most of his supplies so he could fill up his load with as many pounds as possible of visual pornography in as many different types as he could find, on paper as light as he could.
(Wei Wuxian tossed out the mana crystals to make space. Nie Huaisang noticed, but he didn't ask. It's safer to be underestimated.)
He got to take his art supplies with him. He could draw porn with that. Maybe presents for people's lovers. Another way to be valuable.
The induction made him puke, of course.
