Biodata

Power Progression

Appearance

Zi Ji is a mature, elegant woman associated with purple. She first appears suspended in the air beside Di Tian, wearing a long purple dress. 93

• Curvaceous figure.
• Long purple dress.
• Fair, delicate bare feet. 93
• Dark-purple scales emerge when she assumes her true form. 124
• Her true form is the Hell Purple Demon Dragon. 124

Personality

Zi Ji is easy-going and warm toward Xu Xiao from their first meeting, calling herself his “big sister” and readily accepting responsibility for his protection. 93 Their exchanges are often relaxed and teasing, particularly during their journey through the Far North. 102

Despite this approachable manner, she is fiercely protective of Xu Xiao and ruthless when challenged. An insult from Yu Yuanzhen immediately provokes her into attacking him at full force, and she later helps enforce Chuan Ling's demand for Blue Lightning Tyrant Dragon Clan resources. 142

She bears a strong sense of duty toward soul beasts. Zi Ji envies humanity's faster cultivation but does not regret being a soul beast, and she places faith in Xu Xiao's promise to improve the future of the soul beast clan. 98 99

Zi Ji is practical and proactive in pursuing opportunities for the soul beast race. After observing the Earth Cave Demon Spider's rapid growth within the Spirit Pagoda, she personally tests its floors with Zhong Ling, identifies the high-grade energy gained by defeating its main soul beasts, and seeks dedicated access for soul beast cultivation. 205 206 She is also willing to contemplate sacrificing herself as Xu Xiao's soul ring if doing so would advance the revival of soul beasts. 170

Her pragmatism also extends to Chuan Ling's technological development. Alongside Bi Ji and the other fierce beasts, Zi Ji supports the growth of the faction's Soul Tool capabilities, including its progress toward small-scale ninth-level Soul Tool production and research into tenth-level Soul Tools. 353 Xu Xiao explicitly trusts her loyalty and recognizes that she has no ambition to claim the Sun Moon Continent for the soul beast clan. 353

Although normally composed, Zi Ji can be openly resentful when excluded from matters concerning the soul beast clan. She is particularly upset that Xu Xiao did not summon her when the Dragon God briefly appeared. 236

She also shares Xu Xiao's mischievous willingness to scheme against hostile factions. After he explains that the heirs of the Clear Sky Sect and Blue Lightning Tyrant Dragon Clan would otherwise harm soul beasts, she agrees to help find deliberately unsuitable soul beast partners for them. 114

Abilities & Skills

Hell Purple Demon Dragon Transformation

• Can unleash dragon breath in her true form; she uses it to meet Xu Xiao's Ring Detonation-enhanced Ultimate Ice attack during their sparring match. 125

Overwhelming Aura and Suppression

Zi Ji's aura is sufficient to dominate weaker soul beasts and intimidate human soul masters.

• Her released aura kept nearby soul beasts from approaching Xu Xiao's camp in the Far North. 102
• She suppressed the severely wounded Ice Bird with her aura before killing it. 101
• Her unleashed presence forced Yu Yuanzhen to retreat and immediately address her as “Senior.” 142

• Released her aura in the Star Luo imperial palace to support Xu Xiao's demand for the Clear Sky Sect's location, forcing the emperor to cooperate. 112

Combat Strength

Zi Ji is a frontline powerhouse who acts decisively when Xu Xiao needs force behind his plans.

• Crushed an 80,000-year Ice Bird's head with one stomp. 101
• Struck Yu Yuanzhen with a full-force palm attack, sending him flying. 142
• Killed two Clear Sky Sect elders as punishment after Tang Zhan attempted to offer Xu Xiao fake items. 113
• Her presence helped Xu Xiao subdue Vast Sea City's City Lord and the leaders of its five major factions. 148
• Defeated the principal soul beasts on the first six floors of the Spirit Pagoda during her investigation into its effects on soul beast cultivation. 205
• Oversaw the Sun Moon Continent's military after its ruling families surrendered control, stabilizing the continent before Xu Xiao's ascension. 164
• Her investigation with Zhong Ling did not succeed in defeating the principal soul beasts on the Spirit Pagoda's seventh and eighth floors. 205

Soul Core

Zi Ji adopts Xu Xiao's proposed Soul Core method to increase her strength.

• Considers the method feasible and beneficial. 99
• Begins cultivation immediately after returning to the Ice and Fire Yin-Yang Well. 114
• Successfully condenses a purple Soul Core, confirming the method's viability for soul beasts. 124
• Her completed Soul Core leaves her eager to test her increased strength, though Yu Yuanzhen proves too weak to provide a meaningful measure. 146
• Later confirms that she has formed only one Soul Core, despite Xu Xiao's theory that an individual could possess as many as three. 188

Soul Beast Cultivation Assessment

Zi Ji possesses considerable knowledge of soul beast growth, heavenly tribulations, and the potential benefits of Xu Xiao's Spirit Pagoda.

• Explains that heavenly tribulations consist of nine increasingly powerful lightning strikes and warns that even she would not dare intervene directly in Zhong Ling's tribulation. 159
• Deduces that defeating the Spirit Pagoda's main soul beasts grants soul beasts an energy of a higher grade than ordinary soul power. 205
• Seeks an upper floor of the Spirit Pagoda for the soul beast clan after determining its potential to accelerate soul beast cultivation. 205 206
• Selects an initial group of three 30,000-year soul beasts—a Hell Purple Demon Dragon, an Emerald Swan, and a Demon Eye Tree—to enter the Spirit Pagoda's soul beast cultivation arrangement. 210
• Warns that hunting ordinary soul beasts within the pagoda yields slower growth than defeating a floor's principal soul beast, although it remains much faster than ordinary cultivation. 206

Her estimates for a hundred-year soul beast to reach the hundred-thousand-year level by hunting the principal soul beasts vary according to the floor used. 206

Cultivation Guidance and Support

• Guides Dragon Duke and Snake Granny in their cultivation at the Ice and Fire Yin-Yang Well. 236
• Can fly and use her soul power to support Xu Xiao in midair before he acquires flight capability. 100

Relationships

• Xu Xiao — Protected person, partner, and trusted confidant. Di Tian appoints Zi Ji as Xu Xiao's guardian under the cooperation agreement between Xu Xiao and the soul beast clan. 93 She also serves as a cultivation adviser and sparring partner, and Xu Xiao continues to trust her loyalty during Chuan Ling's later technological expansion. 112 124 125 353
• Di Tian — Fellow soul beast and the one who wakes Zi Ji to fulfill Xu Xiao's request for a guardian. 93

• Ice Emperor — Far North ally who reacts to Zi Ji's aura and later guides Xu Xiao and Zi Ji to the Snow Empress. 101 103

Story Role / Major Arcs

Appointment as Xu Xiao's Protector

Di Tian and Xu Xiao establish terms for cooperation between Xu Xiao and the soul beast clan. At Xu Xiao's request, Di Tian awakens Zi Ji—the matriarch of the Hell Demon Dragon clan—and assigns her as his guardian. Zi Ji accepts the role immediately and promises to look after him. 93

Xu Xiao chooses her because Di Tian must devote time to finding and opening Dragon Valley, while Xiong Jun's difficult temperament makes him an unreliable guardian. Zi Ji's strength and suitability as a permanent companion make her a potential pillar of Xu Xiao's developing faction. 93

Far North Expedition

Zi Ji encourages Xu Xiao to travel rather than immediately enter seclusion, and accompanies him on his planned journey to the Far North for his fifth soul ring. Although she notes that suitable hundred-thousand-year soul beasts are already available in the Star Dou Forest, Xu Xiao wants a stronger ring and a new environment to imprint within his Spirit Pagoda. 96 She supports him during his battle with the Ice Bird, prevents the creature from escaping, and personally kills it when Xu Xiao runs out of soul power. 100 101

She accompanies Xu Xiao to negotiate with the Ice Emperor and Snow Empress, supporting his plan for cooperation between humans and soul beasts and confirming the limits on soul beasts becoming gods without the Dragon God's appearance. 103 104

Zi Ji helps explain Xu Xiao's unusual Soul Ring-bestowing ability to the Far North leaders and joins the visit to the Titan Snow Demon King clan in search of a suitable fist-like External Soul Bone. 105 When Snow Empress chooses to take human form to pursue the Ice God's inheritance, Zi Ji promises to protect her while she cultivates anew. 107

Seizing the Clear Sky Sect's Secret Techniques

After Xu Xiao expresses interest in Ring Detonation, Zi Ji volunteers to seize the technique for him. They agree to confront the Clear Sky Sect after completing their Far North expedition. 101

Zi Ji's aura helps force the Star Luo Emperor to disclose the secluded sect's location. At its canyon refuge, she calls Tang Zhan out and supplies the overwhelming force behind Xu Xiao's demands. When Tang Zhan attempts to hand over false items, she kills two elders as punishment, compelling the sect to surrender its genuine secret techniques and resources. 112 113

Soul Core Cultivation

After Xu Xiao proposes a new cultivation approach, Zi Ji agrees to attempt a Soul Core. She returns to the Ice and Fire Yin-Yang Well and begins condensing it. 99 114

After more than two months of cultivation, Zi Ji successfully condenses a purple Soul Core. Her success proves that Xu Xiao's method is viable and encourages the others to consider the same path in the future. 124

She then spars with Xu Xiao on the Spirit Ascension Platform's fifth floor to test both his Ring Detonation training and her improved strength. His enhanced attack forces her to assume her dragon form and counter with dragon breath. Although outwardly calm afterward, she is impressed by the power a Soul King can produce and grows more confident in the future of Xu Xiao and his brothers. 124 125

Chuan Ling Enforcer

Zi Ji becomes a key public figure in Chuan Ling's expansion. Xu Xiao plans to use her and Ye Lin as figureheads while keeping his own position concealed. 136

She accompanies Xu Xiao on his invitation tour to Spirit Hall and the major factions. Her aura draws out faction representatives and deters retaliation, while Tian Meng's concealment allows Chuan Ling to obscure her true strength. 137 138

When the Blue Lightning Tyrant Dragon Clan provokes Chuan Ling, Zi Ji drops her disguise, defeats Yu Yuanzhen, and demands that the clan surrender 90% of its resources and secret techniques within three days. 142 She later receives the clan's delivered resources and assists Xu Xiao with Chuan Ling's affairs. 146 147

Zi Ji also receives visiting representatives during Chuan Ling's public emergence, introduces the faction's medicinal baths, and helps maintain pressure on the major human factions while Xu Xiao's identity as Grand Spirit Lord remains obscured. 143 144

Vast Sea City and Overseas Campaign

Zi Ji accompanies Xu Xiao to Vast Sea City, where her Title Douluo-level strength helps force the City Lord and five major factions into submission. 148 She later travels with Xu Xiao and Snow Empress across the sea to the Sun Moon Continent. 160

Following the Sun Moon Continent's subjugation, the continent's ruling families hand military command to Zi Ji. She maintains order while Xu Xiao prepares the establishment of the Chuan Ling Imperial Dynasty. 164

She also participates in the lengthy return voyage, joining Xu Xiao and the Ice Emperor as they use the Spirit Pagoda to make the ocean crossing more bearable. The group reaches the Douluo Continent's coastline after a year and a half. 165

Dragon Valley Vigil

Zi Ji enters Dragon Valley with Xu Xiao and Di Tian, but remains outside while Xu Xiao and the others undergo prolonged training within its pocket dimension. 176

She waits near Dragon Valley for nearly two years and immediately rushes to the site upon sensing the group's return. Relieved that Xu Xiao is safe, she reunites with him before accompanying him back to the Ice and Fire Yin-Yang Well. 180

Soul Beast Access to the Spirit Pagoda

Zi Ji investigates the Spirit Pagoda's effect on soul beasts alongside Zhong Ling after the Earth Cave Demon Spider rapidly reaches the hundred-thousand-year level. She requests one of the upper floors for the soul beast clan. 205 Xu Xiao later agrees to grant the soul beasts use of the seventh floor under conditions. 206

Zi Ji's investigation establishes that hunting the Spirit Pagoda's main soul beasts provides soul beasts with an unusual high-grade energy. After the arrangement is accepted, she begins by bringing three 30,000-year soul beasts—including a Hell Purple Demon Dragon—to participate in the soul beast cultivation program. 205 210

The initial arrangement allows only three exceptionally talented soul beasts to cultivate there at once, with replacements selected after they reach the hundred-thousand-year level. Zi Ji accepts these terms and agrees to consult the Silver Dragon King about the arrangement and the energy's nature. 206 Xu Xiao subsequently gives her a seventh-floor access token, permitting her to enter whenever she wishes. 211

She later cultivates with Bi Ji on the Spirit Pagoda's ninth floor and remains involved in Chuan Ling's defense and the expansion of its facilities. 251 253

When more soul beasts enter the pagoda, Zi Ji guides them inside under Xu Xiao's arrangements. Their accelerated growth is accompanied by the danger of earlier heavenly tribulations, so Gu Yuena advises them to stop at cultivation bottlenecks rather than advance recklessly. 255

Dragon God Aftermath and Spirit Pagoda Relocation

When Xu Xiao reveals that the Dragon God briefly appeared during events she was not informed of, Zi Ji is upset at having missed the opportunity to meet her former lord. 236

Despite her resentment, she accepts Xu Xiao's explanation that there was no time to summon her and learns of his plan to retrieve the Ice and Fire Yin-Yang Well into the Spirit Pagoda. 236

At the time of their reunion, she is guiding Dragon Duke and Snake Granny in cultivation. Xu Xiao explains that the relocation will remove the need for her to continue staying at the well. 236

Chuan Ling Soul Tool Development

Zi Ji remains involved in the later expansion of Chuan Ling's foundation. Together with Bi Ji and the other fierce beasts, she contributes to the faction's rapid Soul Tool development, which reaches small-scale production of ninth-level Soul Tools and makes progress toward tenth-level Soul Tools. 353

Divine Realm and Underworld Planning

Zi Ji attends the gathering of Chuan Ling's core members within the Spirit Pagoda when Xu Xiao calls for discussion of the future Divine Realm's rules and the Underworld's plans. Xu Xiao identifies those present, including Zi Ji, as founding members close to the heart of his organization and asks everyone to contribute opinions. 385
