Shen Qingqiu sticks out a hand for her to shake in the universal it's a deal gesture. "Cultivation," he says. "The setting I came from—not originally, obviously, because I'm from the real world, but like, just now, before I was here, it's xianxia. Like, ancient Chinese fantasy? Basically I—well, the guy whose body I'm in, technically—cultivated a golden core, which kind of stores up spiritual energy, which I can then use to do stuff like that. And also fly on my sword, and heal really fast, and exorcise ghosts, and a bunch of other stuff. Have you met Lan Wangji? He can use cultivation to talk to ghosts. I was kind of hoping he'd teach me, but I think he sort of hates me now, so." He stops talking, embarrassed by how excited he'd gotten about being able to talk about PIDW as a setting, rather than pretending it was reality or whatever. Nice infodump, you dork.
