Background / History

Physician in Qing Shan Town

Xiao Yi Xian dreamed of becoming an alchemist, but her innate attributes prevented her from pursuing that profession. She instead became a physician devoted to saving lives and worked as a pharmacist at Ten Thousand Medicine Hall in Qing Shan Town. Its business flourished after hiring her, taking customers away from World-Saving Hall 28.

Since childhood, people who discovered her Poison Body had feared and avoided her. Despite its danger, she remained committed to healing others and resisted deliberately consuming poison 26 28.

Meeting Xiao Ze

World-Saving Hall arranged to poison her through a box of pastries. Recognizing an impending outbreak, she fled Qing Shan Town for the Magical Beast Mountain Range. Xiao Ze followed the corrosive handprints she left behind and found her unconscious in a valley 26 28 29.

After absorbing poison from her palms, Xiao Ze explained the name and dangers of her constitution. She initially defended herself with homemade poison powder, but her concern quickly shifted to whether the outbreak had harmed him. His ability to touch her safely convinced her that he also possessed a Calamity Poison Body 27.

She agreed to accompany him after he offered to help her cultivate and control her poison. They returned to Qing Shan Town, found physical evidence of the poisoning plot, and left after Xiao Ze killed its mastermind and accomplice 28 29 30.

While gathering herbs, they discovered a concealed cliffside cave. Xiao Yi Xian received the Seven-Colored Poison Scripture, whose records confirmed Xiao Ze’s explanation of her constitution. She subsequently accompanied him to Wu Tan City and met Xiao Xun’er 30 31 33.

Jia Nan Academy and Dark Alliance Leadership

At Jia Nan Academy, Xiao Yi Xian trained alongside Xiao Ze and Xiao Xun’er, entered the Inner Academy, and reached the Strong Ranking after advancing to Dou Ling. During Origin Heart Flame body tempering, her body released poisonous purple mist that required an elder’s protective barrier 66 98 99 107.

After reaching Dou Wang, she helped protect the Xiao Family’s relocation to Jia Nan City. She later became an Inner Academy elder, although the academy’s leadership debated the danger posed by her constitution 128 153.

During the Inner Academy’s turmoil, she unleashed her poison body and killed several Dou Wang experts, forcing the opposing side to deploy a Dou Emperor against her. Xiao Ze afterward absorbed her excess poison to restore her constitution to its pre-outbreak condition 180.

Her contributions and strength made her the academy’s leading choice, aside from Xiao Ze, to oversee Dark Academy. In his absence, she developed the organization, looked after the Xiao Family, and led the Dark Alliance. Her rule in the Black Corner Region became forceful enough to make numerous factions submit 184 321 335.

Resolving the Calamity Poison Body

After the Misty Cloud Sect conflict, Xiao Ze fulfilled his promise to remove her constitution’s hidden danger. Before entering seclusion, Xiao Yi Xian arranged Dark Academy’s responsibilities, while Azure Scales and Queen Medusa guarded the treatment site 334.

Xiao Ze used his origin essence blood to form a protective rune on her forehead, then gathered the poison throughout her body into it. Condensing the poison in her heart alone took three days. Completion gave her full control and enabled her breakthrough to Dou Venerate 335 336.

The treatment also deepened their relationship. Xiao Yi Xian understood Xiao Ze’s words as assurance that she could receive the same care as Xiao Xun’er, easing the emotional restrictions she had placed on herself 334.

Cold Poison Secret Realm

At higher cultivation levels, ordinary poisons ceased to improve her strength. Seeking a resource potent enough for a Dou Saint, she entered the Cold Poison Secret Realm with Xiao Ze and detected the faint toxicity permeating its mist 474 591 592.

They discovered the Ten Thousand Poisons Pool and identified the danger of a hidden Azure Frost Sky Poison Scorpion. After Xiao Ze captured the scorpion and recruited it as Sky Scorpion, Xiao Yi Xian began cultivating in the pool under its guard 593 595.

She later emerged from seclusion and reunited with Xiao Ze. Rather than merely depleting the pool, her own Dou Saint-stage Calamity Poison Power had increased its toxicity. They then prepared to leave the secret realm 651 652.

Appearance

• Features: Gentle, beautiful features, crimson lips, fair hands, and a fresh, ethereal bearing 27.
• Build: A notably slender waist and delicate-looking figure 27 33.
• Clothing: Appears in a white dress at her first encounter with Xiao Ze and again wears white at her reunion with Xiao Xun’er 27 412.
• Constitution marker: A faint seven-colored line on her lower abdomen identifies the Calamity Poison Body; it lengthens as poison accumulates 27.
• Poison manifestations: Seven-colored hues appear on her cheeks during the early outbreak. Origin Heart Flame tempering makes her face alternate between green and purple while purple mist rises from her body 27 107.
• Calamity Rune: The completed forehead rune shines with purple-gray light when the final portion of poison enters it 336.

Personality

Xiao Yi Xian is compassionate even when frightened. Upon waking beside an unfamiliar man, she prepares to defend herself but soon asks whether her poison has injured him. Her greatest fear is becoming a poison master responsible for countless deaths, directly opposing her wish to save lives 27 28.

She is loyal and considerate toward Xiao Ze and his companions. She guards him while he learns Purple Cloud Wings, supports Xiao Xun’er through cultivation breakthroughs, and treats helping the Xiao Family as a way to share Xiao Ze’s burdens 31 49 80 321.

Her gentleness does not prevent ruthlessness toward enemies. As Dark Alliance leader, she subdues Black Corner Region factions through bloody methods. Xiao Ze’s influence also makes her more cautious: she prepares a poisonous net before confronting two Dou Zong experts rather than attacking without an escape-prevention plan 317 335.

She remains shy about affection and sometimes feels jealous of Xiao Xun’er’s place beside Xiao Ze. Nevertheless, the two develop genuine warmth, and Xiao Yi Xian later greets Xiao Xun’er with sincere happiness 33 98 412 526.

Abilities & Skills

Calamity Poison Body

Her special constitution converts consumed poison into cultivation power, allowing exceptionally rapid early advancement 27 592.

• Poison accumulation: Before treatment, outbreaks increase its toxic power and bring it closer to losing control 26 180.
• Fatal risk: Excessive accumulation can overwhelm the bearer, causing countless poisons to corrode the body from within 26 27.
• Large-scale danger: A complete eruption can poison an enormous region; Xiao Ze warns her that it could turn an empire into toxic land 27.
• External release: Produces corrosive traces, poisonous vapor, and toxic mist capable of endangering nearby people 26 107 121.
• High-level limitation: Ordinary poisons become ineffective at the Dou Saint stage, making rare, exceptionally potent toxins necessary for rapid improvement 474 592.
• Thunder incompatibility: She does not absorb Thunder Power because its destructive energy would harm her without providing a cultivation benefit 406.

Calamity Rune

Xiao Ze’s treatment concentrates her poison into a rune created with his origin essence blood. It suppresses the poison, protects her Soul Power during treatment, and ultimately removes the constitution’s control problem 335 336.

• Stores her condensed Calamity Poison Power 336.
• Absorbs newly generated poison power and converts it into power she can fully control 336.
• Allows subsequent poison consumption and exchanges with Xiao Ze to benefit her without their former double-edged effects 368.

Poison-Power Exchange

Xiao Yi Xian and Xiao Ze exchange Calamity Poison Power through physical contact to improve their cultivation 116 121.

• Before the rune’s completion, exchanges cannot occur too frequently because she struggles to control sudden increases in poison 116.
• Xiao Ze can instead absorb excess poison to stabilize her after an outbreak 180.
• Once her constitution is controlled, frequent exchanges help her improve faster than Azure Scales and Queen Medusa during the documented period 368.

Medicine and Poison Craft

Her training combines practical medical knowledge, medicinal-herb identification, and poison preparation 28 31.

• Makes a poison powder capable of instantly subduing a Dou Zhe 27.
• Accurately identifies rare herbs, including Purple Blue Leaf, White Spirit Ginseng Fruit, Snow Lotus Seed, and Ice Spirit Flame Grass 31.
• Uses Poison Pills prepared through poison-scripture knowledge when Xiao Ze’s pure poison power is unavailable 211.
• Detects extremely faint toxicity in the Cold Poison Secret Realm’s mist and senses poison within its medicinal materials 592.

Combat and Spatial Movement

• Poison warfare: Kills several Dou Wang experts during the Inner Academy conflict 180.
• Poison threads: Creates an encircling net to prevent two Dou Zong experts from escaping and subsequently kills them 317.
• Spatial movement: After reaching Dou Venerate, twists space to cross the distance to Xiao Ze 336.
• Great Heaven Creation Palm: Successfully learns the technique alongside Xiao Ze, Queen Medusa, and Azure Scales 439.

Leadership

• Oversees Dark Academy and develops its strength during Xiao Ze’s absence 184 211 321.
• Promotes experts recruited from the Black Corner Region, while acknowledging that doing so brings both advantages and problems 321.
• Helps coordinate cooperation between Jia Nan Academy and the Anti-Cloud Mist Sect Alliance 319.
• Arranges organizational duties before extended treatment and seclusion 334.

Relationships

• Xiao Ze — Rescuer, cultivation partner, and romantic attachment. His acceptance gives her hope of controlling her constitution; she later kisses him before beginning seclusion in the poison pool 27 28 334 595.
• Xiao Xun’er — Fellow cultivator and sister-like companion. Initial jealousy develops into cooperation and sincere affection, although Xiao Yi Xian still feels some bitterness over Xiao Ze’s public commitment to Xun’er 33 49 412 526.
• Azure Scales — Companion whom she helps cultivate by capturing snake-type magical beasts. Azure Scales guards her treatment, and the two offer each other comfort during Xiao Ze’s engagement announcement 180 336 526.
• Queen Medusa — Fellow companion and ally who guards the cave during her treatment; the two also cultivate Great Heaven Creation Palm together 336 439.
• Great Elder — Academy authority involved in approving her elder application and Dark Academy responsibilities. Her dangerous constitution makes his support cautious 153 184.
• Xiao Yan — Xiao Ze’s brother and an ally in negotiations against the Misty Cloud Sect. She accompanies him back to the Inner Academy and helps discuss cooperation 317 319.
• Xiao Zhan, Xiao Ding, and Xiao Li — Members of Xiao Ze’s family whose safety and development she helps maintain during his absence 128 321.
