"As I thought," Shen Yuan says quietly. "Lan-gongzi is a Coldblood." He hands Lan Xichen a partially-dampened towel to clean his hand with. "He may find that he actually has greater facility with temperature-based magic now, once he's gotten in some practice. And of course he's already noticed his new resistance to cold weather."

Shen Yuan hesitates for a moment before answering the question that's really been burning on his mind. He'd assumed this would be the case given Lan Xichen's demonstrated power levels and figured it wasn't really his business anyway, but since they're on the subject... "Lan-gongzi still possesses his golden core, correct?"
