Xuan Nu, also known as Xuan Nu of the Nine Heavens, is an ancient female immortal and a Taoist goddess from the pre-Qin era. She is renowned as the teacher of the Yellow Emperor, having instructed him in the Arts of the Bedchamber, which ultimately led to his legendary Ascension after bedding three thousand women. Qing Ni selected this prestigious identity to impersonate when interacting with the First Emperor, who recognized the name's significance and was deeply honored by what he believed to be a genuine encounter with such a revered immortal figure. The title carries connotations of both spiritual mastery and esoteric teachings.
