Also known as Master Sun or Xiao Sun, a middle-aged reclusive master under forty with a goatee. He is from the Sun lineage, which has long practiced the arcane. He specializes in astrology, geomancy, and divination but his family's secret exorcism techniques have stagnated. He came to the Li family seeking to advance his cultivation by using the divine power of Li Moying and Wanwan. He showed deep fear and deference toward Li Moying, calling himself 'old servant.'
