Ancestor Grandma is the spirit residing within Jiang Yi's Spirit Tablet, claiming to be the ethereal fairy sister who appeared in Jiang Yi's dream. She declared Jiang Yi the 108th-generation successor of Wuming Daoguan and taught her fire-conjuring incantations. Described as fierce and demanding, she complains about the sect's decline from a grand courtyard to a dilapidated wooden cabin. She senses red cash on Jiang Yi and wastes it on snacks, roast chicken, clothes, and novels, burning the offerings. Restless for years, she has been urging Jiang Yi to leave the mountain, tormenting her with dreams where Jiang Yi is jolted like a dog. Despite her complaints, she relies on Jiang Yi to sustain the sect, and Jiang Yi suspects the misfortune lies with Ancestor Grandma rather than herself.
