Wu Xue, the Third Sister, is an extraordinarily beautiful she‑wolf with entirely gray‑white fur that shines under the moonlight. She is elegant and proud, with a taste for only the finest mate — she dreams of a pure white snow wolf from the northern mountains. She shares a close bond with Lin Xiaoxiao, often allowing the girl to snuggle beside her. She is sharp‑tongued (she calls Xie Xiaoran a fool) but kind-hearted. Her beauty attracts many suitors who leave gifts at the cave entrance. Lin Xiaoxiao adores her and often tries to comfort her when the Wolf King pressures her to find a partner.
