She nods, touched at his concern. "There are herbs that help, but I don't know which—I'm not the most diligent patient. I simply take what is prescribed. But Lan Wangji gave me some medicine from his lands to help. Otherwise, cold and damp aggravate it, and dry heat is beneficial." She refrains from mentioning that she's already running low on Lan Wangji's herbs, and the fact that autumn is in the air bodes poorly. If she's meant to die here, there's no point in causing Magnus distress over it. She's already snatched her life from the king of hell a number of times; it's only right he should claim it eventually. She would just rather give it to Nangong Jingnu.
