Power Progression

Stage / Realm / Level	Chapter	Notes
Rank 50, awaiting a fifth soul ring	47	Reveals that she has reached rank fifty. Requests a soul beast just over ten thousand years old, explaining that its attribute is unimportant for her food-type martial soul.
Five-Ring Soul King	74	Demonstrates her fifth soul skill, Soul Power-restoring Amethyst Orange, during the Second Team selection battle. The supplied passages do not identify the ring she ultimately absorbed.

• Medicinal assistance: Ju Zi credits cultivation medicine with allowing her to approach the Five-Ring Soul King stage before twenty; without it, she believes she might still be a Three-Ring Soul Elder 48.
• Cultivation ceiling: She expects breaking through rank sixty to be almost as difficult for her as for an ultimate-attribute soul master. This limitation helps motivate her departure from Mingde Hall 117.
• Engineering level: A Level 5 compressed explosive exceeds her independent capabilities during the workshop scene; Lin Qing helps her resolve its design problems 46.

Background / History

Ju Zi’s father was a chef who was killed by the Star Luo Empire. Her mother subsequently became gravely ill from grief and died. These losses left Ju Zi orphaned and determined to avenge her parents, particularly against White Tiger Duke Dai Hao and his family 48 50 94.

She later became Crown Prince Xu Tianran’s maid. During the Second Prince’s assassination attempt, she took a potentially fatal blow intended for Xu Tianran, earning his trust and unusually free access to his residence. Her obedient conduct concealed a practical objective: obtaining the empire’s military power to pursue revenge 53 54.

Appearance

Ju Zi has exceptionally fair, delicate skin and an innocent-looking face. Her soft, sometimes sleepy expression contrasts sharply with her political caution and capacity for violence 31 47 100.

• Skin: Translucent, snow-white, and described as remarkably smooth 31 46 47.
• Expression: Misty eyes and a dazed look at her tournament debut 31.
• Distinguishing feature: A slender, long neck 46.
• Clothing: Wears fitted white clothing during the Jingyang expedition and an orange-red gown at the imperial birthday ball 47 118 119.

Personality

Ju Zi is gentle, playful, and attentive with people she trusts. She exchanges teasing compliments with Lin Qing, accepts criticism of her cooking, and expresses gratitude through meals and caregiving. Her years in the Crown Prince’s residence have also taught her to read expressions and adjust her behavior to others’ moods 46 52 98.

Her ambition is inseparable from grief. She wants military command because Star Luo will not surrender Dai Hao; she acknowledges that, if it did, she would no longer need to pursue an army career. Beneath her innocent appearance lies a ruthless resolve, demonstrated when she deliberately cripples Dai Yueheng during the tournament final 94 100.

She recognizes her weaknesses without readily accepting them as permanent. Though frightened of facing Lin Qing and inexperienced in combat, she enters their match rather than retreat and later requests intensive training so she can contribute more than food-type support 31 75.

Her apparent loyalty to Xu Tianran becomes increasingly conditional. Once she trusts Lin Qing, she shares the crown prince’s secrets and eventually proposes replacing him rather than submitting to his plans for her future 54 55 121.

Abilities & Skills

Food-Type Martial Soul

Ju Zi produces fruit with supportive effects. Her food-type skills make her particularly useful to soul engineers whose weapons consume large amounts of soul power 48 74 75.

Soul Skill	Effect	Documented Use
First skill: sour green tangerine	Increases spiritual power by approximately 10% 48.	Uses it on Lin Qing during the Jingyang expedition 48.
Second skill: sweet yellow tangerine	Heals physical injuries and eases muscle fatigue 48.	Provides recovery support to Lin Qing 48.
Fifth skill: Soul Power-restoring Amethyst Orange	Rapidly restores 30% of the consumer’s soul power 74.	Sustains Xiao Hongchen and Keke’s heavy cannon fire during team selection 74 75.

• Her food-type martial soul allows flexibility when selecting a soul beast’s attribute for a new ring 47.
• During team battles, she positions herself behind heavier attackers rather than acting as a frontline fighter 74.

Soul-Tool Research and Fabrication

Ju Zi’s strengths lie in theory, inventive design, and manufacturing rather than practical combat 31 36 43.

• Excels in the Hongchen Class’s written theory examination 36.
• Earns admission principally through her soul-tool manufacturing score despite a weak combat result 43.

• Works on orange-shaped compressed explosives, but needs Lin Qing’s assistance with a Level 5 version 46.
• Participates in field testing the All-Terrain Automatic Detection Soul Tool across forest and underwater routes 47.

Combat and Targeted Training

Ju Zi initially relies on explosive soul tools and support skills. Lin Qing later helps her develop practical cannon use and attacks tailored to the White Tiger martial soul 31 75 82.

• Uses martial-soul oranges alongside orange-shaped high-explosive soul tools in her first match against Lin Qing 31.
• Learns basic sword forms, but performs them rigidly and lacks an instinctive feel for melee combat 75.
• Studies the White Tiger lineage’s familiar soul skills and Dai Yueheng’s individual combat habits 82 93.
• Blocks Dai Yueheng’s White Tiger Annihilation Strike with an Invincible Shield, then uses the Hellfire Cannon to blast away an arm and a leg 100.

Cooking and Dancing

Ju Zi inherits her father’s culinary aptitude and is also a skilled dancer 52 113 119.

• Prepares Bronze Hellfire Dragon meat during the Jingyang expedition 47.
• Brings Lin Qing an elaborate recovery feast and welcomes his criticism that her osmanthus cakes are too sweet 52.

• Flying Soul Tool — Used during the Jingyang escape; shot down before Lin Qing rescues her and Keke 50 51.

• Invincible Shield — Protects her from Dai Yueheng’s attack in the tournament final 100.
• Hellfire Cannon — Used to cripple Dai Yueheng in front of Dai Hao 100.

Relationships

• Keke — Best friend and fellow student under Xuan Ziwen. They survive the Jingyang crisis together, care for Lin Qing, and plan to enlist together with Keke serving as Ju Zi’s deputy 46 50 52 117.
• Xu Tianran — Crown prince and patron whose trust she earned by protecting his life. He attempts to use her relationship with Lin Qing to secure imperial support and demands that she produce an heir; she privately rejects this future 53 57 109 121.
• Xuan Ziwen — Hongchen Class instructor and research mentor. Recognizes her inventive manufacturing talent and supervises her five-person study group 43 46.
• Grandma Lin — Warmly approves of Ju Zi’s considerate behavior and cooking, regarding her and Lin Qing as a suitable match 98.
• Zi Mu — An admirer whose advances she rejects. She tells Lin Qing that Zi Mu lacks qualities she likes, including sufficiently good looks 46.
• Ye Guyi and Meng Hongchen — Teammates whose affection for Lin Qing creates tension around Ju Zi’s growing closeness to him 52 98 119.
• Dai Hao and Dai Yueheng — Targets of her vendetta against the White Tiger Duke’s family. She studies Dai Yueheng’s fighting habits and severely injures him during the final 93 94 100.
