Background / History

Childhood and Qingshan Town

When Xiao Yi Xian was a child, her Calamity Poison Body erupted and killed everyone else in her village. As its sole survivor, she feared repeating the catastrophe and wished to escape an existence in which her own body could endanger others 166.

She became Qingshan Town’s only physician, treating injured mercenaries and earning considerable respect through her work. At this stage, she mixed medicinal herbs with ordinary flames rather than refining true medicinal pills 143. Her reputation discouraged Mu Li from openly offending her, although she recognized his intentions and disliked his persistent attention 144 145.

Meeting Su Mu and Xiao Yue

Xiao Yi Xian met Su Mu and Xiao Yue in the Monster Beast Mountain Range after the pair became lost. She reassured the accompanying mercenaries, befriended Xiao Yue, and brought the two travelers to Myriad Medicine Hall in Qingshan Town 143 146.

Xiao Yue repeatedly encouraged her to become Su Mu’s disciple. Xiao Yi Xian hesitated because she considered her talent unremarkable, feared his reaction to her physical condition, and did not want to burden him 145 146.

When Mu Li attempted to take Xiao Yue away, Xiao Yi Xian intervened and offered the protection of Myriad Medicine Hall. The mercenaries’ continued surveillance eventually threatened the hall’s business, prompting its owner, Mr. Yao, to press her for a solution 147 148 150. She proposed escorting her guests out safely, still unaware of their true strength 151.

Becoming the Third Disciple

After witnessing Su Mu’s abilities and concern for her, Xiao Yi Xian accompanied him and Xiao Yue to a treasure cave in the Monster Beast Mountain Range 161 164. A Poison Scripture found inside described the Calamity Poison Body, alarming her and leading to a discussion of its dangers 164 165.

She disclosed her constitution and childhood tragedy to Su Mu. He promised to help her, although the solutions he initially described were beyond his immediate resources. Despite worrying that accepting a master for treatment might seem selfish, she chose to trust him and performed the discipleship ceremony, becoming his third disciple 166.

Su Mu transmitted the cultivation portion of the Myriad Medicine Codex of Poison and Healing. Its initial circulation was painful, but it brought her medicinal and poisonous energies into harmony. She subsequently reported unprecedented health and effortless control over her Dou Qi 169 170.

Training and the Iron Mercenary Group

Xiao Yi Xian chose to continue traveling with Su Mu. During secluded training in a valley, she studied medicinal materials, refined medicine and poison, and rapidly increased her strength 172 173 175.

In Black Rock City, she incapacitated He Qiang’s guards when they threatened her master 185. Later, at the Iron Mercenary Group’s headquarters, she challenged Xiao Li for provoking Su Mu and defeated him, establishing her prestige among the mercenaries 201 202 222.

Her intimidating reputation softened as she distributed ordinary pills in return for help obtaining ingredients. She also developed a moisturizing, skin-nourishing face mask, improving her relationships with the group’s members 222.

Appearance

Xiao Yi Xian has a gentle, graceful appearance and a distinctive temperament that Su Mu finds increasingly attractive the longer he observes her 143 164.

• Gentle features: Her beauty contrasts with the danger of her constitution and poison techniques 166 222.
• Desert-related changes: During her stay in the desert, she notices darker, rougher skin, motivating her cosmetic research 222.

Personality

Xiao Yi Xian is compassionate but not oblivious to danger. Her medical work saves many mercenaries, yet she recognizes Mu Li’s intentions and understands how a lack of strength leaves people vulnerable to coercion 143 145 152. Although accustomed to death in a mercenary town, she is initially shaken by Xiao Yue’s ruthless fighting 155.

Her reluctance to accept Su Mu stems from insecurity and consideration for others rather than indifference. Once she trusts him, she openly discusses her cultivation needs and becomes fiercely protective of him, confronting opponents who threaten or insult him 146 166 170 185 201.

She is generous with Xiao Yue and diligent in her research. She gives up a valuable flying technique for her friend, offers medicinal materials to her master, and insists on testing cosmetic products on herself before allowing others to use them 167 168 222. Her quieter demeanor also includes a playful side: she struggles to suppress laughter at Xiao Yue’s embarrassing mishaps 163 171.

Abilities & Skills

Calamity Poison Body

Her innate constitution converts ingested poison into poison battle qi, allowing rapid cultivation without conventional painstaking training 164 165.

• Poison serves as an energy source rather than an ordinary threat to her body 164.
• Uncontrolled toxic power can turn against its host, causing immense suffering and widespread destruction 165 166.
• Its childhood eruption left her the only survivor of her village 166.
• Su Mu identifies merging with Netherworld Poison Fire or forming a Poison Pill with Heavenly Flame assistance and special materials as possible control methods; neither is used for her immediate treatment 165 166.

Myriad Medicine Codex of Poison and Healing

This peerless cultivation technique converts both medicinal and poisonous power into usable energy. Maintaining their balance allows Xiao Yi Xian to control her Calamity Poison Body 168 170.

• Restores harmony between her two internal energies and makes her Dou Qi easy to command 170.
• Supports rapid growth through consuming medicines and poisons; cultivation remains faster than ordinary people’s even without consuming them 170.
• Requires suitable medicinal resources to balance poison intake 170.
• Contains extensive knowledge of medicinal materials, pill refinement, and poison preparation 168.
• Can eventually produce the Myriad Poison Saint Body and Myriad Medicine Saint Body at its peak; she has not attained these constitutions in the documented chapters 168.
• Her first consecutive breakthroughs draw on accumulated medicine and poison, so she expects later sessions to be less dramatic 171.

Medicine and Pill Refinement

Xiao Yi Xian begins as a skilled physician and develops true pill-refining abilities under Su Mu’s instruction 143 173.

• Treats injured mercenaries using prepared herbal medicines 143.
• Prepares ointment and offers it to Xiao Yue after a flying mishap 171.
• Uses the Golden Jade Exquisite Lamp for refinement. Her early pills contain too many impurities for ordinary people, but their mixture of medicine and poison suits her cultivation 173.
• Practices with low-grade ingredients and gives away ordinary pills to compensate mercenaries who help supply materials 222.

Poison Techniques and Combat

Her poison expertise lets her threaten opponents beyond the level of ordinary Dou Zhe 185.

• Incapacitates He Qiang’s guards with a light scattering of powder 185.
• Can prepare poisons capable of dealing with Dou Shi and posing a threat to Da Dou Shi 185.
• Uses poisonous silver needles and dark green Dou Qi gauze against Xiao Li 202.
• Knocks a Rock Snake unconscious with poison before Su Mu uses it to test Qing Lin’s ability 208.
• Exercises restraint during the match with Xiao Li; Xiao Yue explains that a serious poison attack could have prevented him from entering the stage at all 202.

Cosmetic Research

She applies medical knowledge to skin care after experiencing the effects of the desert climate 222.

• Successfully develops a moisturizing, skin-nourishing face mask using special desert ingredients 222.
• Does not achieve a successful whitening formula during the documented experiments 222.
• Tests preparations on herself first and keeps possible side effects within controllable limits 222.
• Offers cultivation resources to female volunteers participating in product trials 222.

Equipment / Items

• Seven-Colored Poison Scripture — Cave treasure describing poison preparation and the Calamity Poison Body; Su Mu gives it to her as his first gift as her master 164 166.
• Golden Jade Exquisite Lamp — Peerless refining tool obtained through her Goddess Gift Pack and later given to her by Su Mu. Her early refining sessions produce no failures, which the narration attributes tentatively to the lamp’s hundred-percent success rate 167 173.
• Roaring Lion Chant — Mysterious Tier High-Level sonic-wave Fighting Skill allocated to her from a stone box; she shows little interest in it, and no use is documented 167.
• Poisonous silver needles — Concealed weapons used during her match with Xiao Li 202.
• Medicine and poison powders — Prepared substances consumed to fuel and balance her cultivation 170.

Relationships

• Su Mu — Master. His medical knowledge, protection, and help controlling her constitution overcome her initial hesitation; she later defends him against threats and insults 150 166 169 185 201.
• Xiao Yue — Close friend and senior disciple sister. Xiao Yue arranges their first introduction to Su Mu, supports her after learning her secret, and remains concerned about her health despite envy of her cultivation speed 145 166 169 170.
• Mr. Yao — Owner of Myriad Medicine Hall. Grants her considerable authority but pressures her to resolve the mercenary surveillance affecting his business 150.
• Mu Li — Unwanted pursuer. She recognizes his intentions, keeps him at a distance, and opposes his attempts to take Xiao Yue away 145 146 147.
• Xiao Li — Sparring opponent. She challenges him for provoking Su Mu and defeats him, earning prestige within his mercenary group 201 202 222.
• Qing Lin — Fellow disciple. They follow Su Mu’s instructions during the Rock Snake test, with Xiao Yi Xian’s poison helping prepare the beast 208.
