Background / History

Hu Jiujiu first appears in the Shennong Mountains while still in an incomplete fox transformation. She helps save the injured Yao Chen from pursuing Da Dou Shi, swallowing two attackers after their Dou Qi attacks fail to pierce her teeth. She initially conceals her identity under the name “Little Demon” while joining Lin Yu and Yao Chen on their attempt to leave the mountains. 1 2

During the journey, she steals a Fire Ant Crystal and permits Lin Yu to refine it into a fifth-grade Blazing Fire Pill. Impressed by his skill, she gives him an exceptional cache of medicinal ingredients, including seventh- and eighth-grade herbs and a ninth-grade Flame Demon Heart. Despite the danger of revealing such resources, she entrusts them to him for future pill refinement because she considers him “not an outsider.” 3 4

After being found by a guard sent by her father, Hu Jiujiu returns to the Demon Clan rather than forcing Lin Yu to accompany her. She leaves him a stone-slab message revealing her true name, asking him to visit Demon Valley willingly, and warning him to stay safe. 7

In Demon Valley, Hu Jiujiu begins constructing an Alchemist Hall and medicinal-herb facilities. Human cultivators are forcibly used as laborers under the threat of her magical beasts, though the workers are paid and released when the hall is completed. 15 20 When Lin Yu reunites with her, she enthusiastically claims him as hers, protects him and his companions from the valley’s black bear, and supports his pill-refining ambitions. 16 17

Hu Jiujiu leads Lin Yu through the mountains to collect Beastfire from high-tier magical beasts. Her authority allows them to obtain nineteen seventh-tier and eleven eighth-tier Beastfires with little resistance. 19

She later spends years cultivating a technique and completes her transformation into a humanlike form while retaining her fox ears and tail. Lin Yu’s return to Demon Valley prompts an emotional reunion, and she subsequently accompanies him to Sacred Pill City. 61 63

When Demon Valley is attacked by Soul Clan experts, Lin Yu returns to defend Hu Jiujiu and her family. After the attackers withdraw, she is reunited with her injured father, the Demon Saint, at the Ashen Ruins Territory. 83 84

Appearance

Hu Jiujiu’s appearance changes substantially after completing her transformation.

• Incomplete transformation — She has a foxlike face with a protruding nose and mouth, upright fox ears, amber eyes, and a fluffy tail; her features are explicitly described as visibly non-human. 1
• Completed transformation — She becomes slender and graceful, with an exquisitely beautiful human face, waist-length silver-white hair, amber eyes, fox ears, and a bushy tail. 61
• Typical clothing — She is seen in emerald-green robes during her early journey and later wears dresses such as a light-pink gauze dress. 1 63
• Expressive traits — Her ears and tail visibly react to excitement, embarrassment, anger, and happiness. 4 17 61

Personality

Hu Jiujiu is lively, mischievous, proud, and intensely expressive. She argues readily with Yao Chen, boasts about her instincts, becomes excited over candy pills, and treats waterfalls, grilled food, and travel with childlike enthusiasm. 2 4 5

She is also unusually trusting once she accepts someone. She gives Lin Yu rare medicinal materials without hesitation, insists that he is not an outsider, and repeatedly supports his alchemy despite the danger and expense involved. 3 4 17

Her affection for Lin Yu is direct and possessive. She calls him “hers,” openly defends him from criticism, becomes deeply emotional when reunited after years apart, and is quick to forgive his absence when he brings her candy pills or rare gifts. 16 18 61 70

Away from Lin Yu, Hu Jiujiu can be domineering and volatile. She disciplines subordinates and magical beasts harshly, commands fear from Demon Valley’s workers and guards, and uses her status to get what she wants. 15 16 Her softer side emerges most clearly around family: mention of her mother leaves her briefly vulnerable, and she tearfully embraces her father after Demon Valley’s crisis. 5 6 84
