Background / History

Zi Ji belongs to the dragon population of the Star Dou Great Forest. Gu Yuena regards her as a promising member of the dwindling Dragon Clan: her Hell Demon Dragon King bloodline possesses yin-water and devouring attributes, and she is worth nurturing toward greater strength 29.

When Gu Yunxiao begins formal cultivation, Bi Ji is assigned to teach theory and cultivation, while Zi Ji takes responsibility for practical combat. At the ceremony establishing him as the Soul Beast Clan’s young lord, Zi Ji initially teases him, then becomes serious following Di Tian’s warning. After witnessing Yunxiao’s martial soul and the Dragon God’s authority within it, she kneels with the other ferocious beasts and pledges her service 10 12.

She remains his instructor through the following four years. Before he leaves for the human world, Gu Yuena selects Zi Ji and Bi Ji as his guardians and conceals their soul-beast auras. The arrangement also gives Zi Ji access to Yunxiao’s bloodline power, which Gu Yuena expects to benefit her development 16 17 28 29.

Appearance

Zi Ji’s human form is described as a beautiful, voluptuous woman whose fiery bearing contrasts with Bi Ji’s gentleness 12.

• Hair: Purple, draped over her shoulders 12.
• Eyes and lips: Deep-purple eyes and purple lips 109.
• Build: Fair skin, a narrow waist, and long, slender legs 12.
• Usual clothing: Appears in purple clothing during Gu Yunxiao’s forest training 16.
• Disguise: Wears a black robe and mask during the ambush on Xuan Zi and Xian Lin’er 159.

Personality

Zi Ji is playful, provocative, and openly affectionate toward Gu Yunxiao. Even as a ferocious beast, she can present herself like a lively young woman rather than an imposing elder. She dislikes being treated as an outsider and readily volunteers to help him or serve as his sparring target 17 18.

Her confidence conceals insecurity about her place in his heart. She recognizes that his childhood bond with the Three-Eyed Golden Lion is stronger than her own relationship with him, but refuses to give up, believing affection can deepen over time. Her initial hesitation before expressing her feelings also shows that she fears rejection despite her teasing manner 17 42 43.

She combines personal attachment with dependable service. Although disappointed when an assignment separates her from Yunxiao, she is satisfied to be useful to him. Her rivalry with Bi Ji includes smug teasing, but does not prevent gratitude, cooperation, or consideration 61 62 64 82 83.

Toward opponents, Zi Ji can be cold and contemptuous. She resents Mu En’s use of the title “Dragon God Douluo,” and dismisses Xuan Zi as weak after defeating him. Nevertheless, she accepts Bi Ji’s reminder that Yunxiao ordered a beating rather than a killing 37 161.

Abilities & Skills

Hell Demon Dragon King

Zi Ji is a True Dragon whose natural attributes are yin water and devouring. In human-facing combat, she manifests a Hell Demon Dragon martial soul; her dragon form is also called the Abyssal Demon Dragon 29 60 159 161.

• Absorbs large quantities of cold-spring water as cultivation nourishment 61 64.
• Possesses an unusually pure dragon bloodline, immediately recognized as dangerous by Shrek’s elders 159.
• Overpowers Xuan Zi’s Taotie Avatar and knocks him out of it 159 161.
• Can exert enough aura pressure to crush Yan Shaozhe’s Martial Soul Avatar 168.

Dragon Clan Combat Instruction

Zi Ji teaches Gu Yunxiao dragon combat techniques rather than merely elemental control 17.

• Arranges increasingly difficult practical lessons in response to his requests 23.
• Uses a thousand-year Titan Giant Ape and a thousand-year Dark Gold Terrorclaw Bear as sparring opponents, including a two-on-one test 23 24.

• Carry him at high speed without noticeably slowing down 60.
• Shield him from strong winds with soul power 60.
• Guard cultivation sites and move weaker companions away from dangerous breakthrough energy 163.
• Their original guardian assignment covers emergencies and major matters, not ordinary disputes among Yunxiao’s peers 28.

Concealment and Covert Operations

• Distributes dragon blood to selected students through staged opportunities 131.
• Personally verifies that the recipients finish refining it before reporting success 135.
• Spreads information intended to prompt Tang Ya to seek out Bei Bei 131.

Bloodline Enhancement and Suppression

Refining Gu Yunxiao’s blood essence strengthens Zi Ji’s Dragon Clan bloodline, but also increases her instinctive submission to him. She identifies this effect and reports it, helping him recognize the wider uses of his bloodline 60 77.

• Her True Dragon bloodline has the potential to advance toward a Dragon King bloodline; Yunxiao promises to help her pursue it 60 61.
• Dragon King bloodline advancement is described as comparable to becoming a god without obtaining a divine position; Zi Ji has not yet achieved it 61.
• Yunxiao’s aura can frighten her and make resistance difficult despite her greater cultivation strength 64 74.
• The bloodline link appears to let Yunxiao sense her thoughts, though its full capabilities remain under investigation 77 78.

Relationships

• Gu Yunxiao — Young lord, student, protected charge, and romantic partner. Zi Ji teaches his practical combat, serves him in the human world, and receives bloodline-enhancing support from him 17 28 42 60.
• Gu Yuena — Dragon Clan sovereign and patron. Selects Zi Ji as Yunxiao’s guardian, conceals her aura, and encourages her bloodline development 28 29.
• Bi Ji — Fellow guardian and affectionate rival. Their teasing competition gives way to mutual support at the cold spring, and they cooperate in protecting Yunxiao 46 62 64 163.
• Three-Eyed Golden Lion — Rival for Yunxiao’s attention. The Lion distrusts Zi Ji’s teasing, while Zi Ji envies their longstanding closeness 10 12 17.
• Snow Empress and Ice Empress — Fellow soul-beast allies and Dragon God Hall associates. Zi Ji guards their heavenly tribulations and congratulates them afterward 68 69 77.
• Xuan Zi — Combat opponent. Zi Ji defeats him during a masked ambush, but lets him flee in accordance with Yunxiao’s orders 159 161.
