Background / History

Physician of Qingshan Town

Xiao Yi Xian works at Myriad Medicine Hall, treating mercenaries injured in the Monster Mountain Range. Her gentle manner and medical skill attract customers who specifically seek her treatment. Despite working as a physician, her ambition is to become an alchemist 50.

Her earlier life is only briefly hinted at. Being called “Xian'er” brings back painful memories; she recalls that she last heard the name before turning ten. She conceals her distress rather than explaining her past to Yan Lin 51.

Becoming Yan Lin’s Disciple

Yan Lin approaches her at Myriad Medicine Hall and offers to accept her as his disciple. Initially skeptical because he appears close to her own age, she accepts after he demonstrates his strength and presents medicinal pills, Earth-grade cultivation methods, and Profound-grade Dou Techniques. His concealed motives include copying her Tribulation Poison Body and drawing her into his service 50.

Before leaving Qingshan Town, she persuades Yan Lin to spare the hall’s staff and owner, Mr. Yao. She also shares the location of a secluded valley suitable for cultivation and prepares supplies for their journey 52 56.

Poison Master’s Ruins and Valley Training

On the way to the Monster Mountain Range, Xiao Yi Xian learns that Mu Li has used her assistant, Li Fei, to obtain information about a cave ruin she discovered. His plan to follow her and seize its treasures leaves her frightened and furious. Yan Lin kills Mu Li and subsequently eliminates the Wolf Head Mercenary Group 57 59.

Inside the ruins, the Seven-Colored Poison Scripture reveals her constitution and its fatal consequences. Her initial despair gives way to hope when Yan Lin explains that the Tribulation Poison Body can be controlled through a Poison Pill. She also learns the Purple Cloud Wings before moving with him to the secluded valley 60 61.

Yan Lin subjects her to demanding practical combat training despite her lack of fighting experience. She perseveres through exhaustion, then continues following his regimen while he is away. Her cultivation reaches four-star Dou Zhe, and she later checks on him daily during his breakthrough seclusion 62 76 77.

Life at the Saint King Palace

After traveling through Black Rock City, Xiao Yi Xian learns that Yan Lin is the Snake People Clan’s Saint King. She accepts his identity without fearing him personally, although her broader apprehension toward the Snake People has not entirely disappeared 79 80 84.

Yan Lin brings her before Medusa and emphasizes her potential as a future pillar of the clan. She settles into the Saint King Palace and quickly becomes close to Qing Lin. Her feelings for Yan Lin also become harder to hide, particularly when she considers his relationship with Medusa 85 86 87 88.

She continues preparing and consuming increasingly potent poisons. Yan Lin warns her against excessive consumption and works toward obtaining the ingredients and alchemical expertise needed to control her constitution; these preparations remain incomplete in the supplied material 100 118 149.

Appearance

Xiao Yi Xian is a young woman whose beauty is distinguished by a fresh, ethereal manner rather than an overwhelming appearance 50.

• Hair: Silky, dark hair 84.
• Eyes: Clear, bright eyes repeatedly compared to spring water 50.
• Build: A slender waist 61.
• Clothing: Initially wears a pale white dress; later appears in light or pale purple dresses 50 62 76.
• Expression: A gentle smile while treating patients; becomes noticeably livelier and more playful around Yan Lin 50 59.

Personality

Xiao Yi Xian is compassionate and treats injured patients equally, regardless of their appearance or background. Her concern extends to intervening when Yan Lin intimidates Myriad Medicine Hall’s staff and owner 50 52.

She is curious but not indiscriminately trusting. She initially questions Yan Lin’s qualifications and later recognizes that his explanation of the sinister Myriad Soul Banner is dishonest. Nevertheless, she chooses not to press him because she believes he will not harm her 50 59.

Her determination shows in enduring painful technique cultivation and high-intensity sparring. She is also frugal: when offered a fourth-grade Restoration Pill for soreness, she considers it wasteful and suggests ordinary pain-relieving powder instead 60 62.

Around Yan Lin, her reserve gradually gives way to affection, teasing, and a desire for companionship. She becomes disappointed when he must enter seclusion and struggles to voice her distress over his closeness to Medusa 62 76 87 88.

Abilities & Skills

Tribulation Poison Body

An innate constitution that allows Xiao Yi Xian to grow stronger by consuming poison. Her attribute panel identifies it separately from cultivation talent and lists no alchemy talent 60 63.

• Converts consumed poison into cultivation gains, enabling unusually rapid advancement 76.
• Makes poisonous ingredients and mushrooms beneficial to her rather than ordinary dietary hazards 76.
• Produces seven-colored poisonous mist during cultivation 100.
• Requires time to absorb Poison Power; sufficiently intense consumption can leave her unconscious until the process finishes 100 128.
• Creates a powerful craving for poison, making repeated consumption difficult to restrain 100.
• Carries a catastrophic eruption risk. Xiao Yi Xian states that an outbreak can destroy all life within a thousand miles, while the scripture describes possessors eventually dying in agony from accumulated poisons 60.

Poison Pill Control Methods

Yan Lin presents the Poison Pill Method as a way to control—not cure—the Tribulation Poison Body. Condensing accumulated toxins into a Poison Pill would allow its possessor to manipulate internal Poison Power freely 60.

• Her attribute panel includes the Netherworld Poison Fire Pill Condensing Method, which uses Netherworld Poison Fire to refine Tribulation Poison Gas 62 63.
• The method requires a seventh-tier Spirit Absorption Pill, alongside the poison fire and other preparations 63.
• Her early cultivation is insufficient to refine the Netherworld Poison Fire, delaying the plan 63.
• Yan Lin considers temporarily sealing an outbreak through Venerable Tianhuo if permanent control cannot be prepared in time 100.
• No successful Poison Pill condensation or refinement of the Netherworld Poison Fire is documented for her 149.

Medicine and Poison Preparation

• Treats and bandages mercenary injuries at Myriad Medicine Hall 50.
• Recognizes rare medicinal herbs in the Poison Master’s ruins, including Snow Lotus Seed, Purple Blue Leaf, and Ice Spirit Flame Grass 59.
• Identifies highly toxic medicinal ingredients and prepares poisons for her cultivation 76 100.
• Produces increasingly potent poison, though its strength remains insufficient for Yan Lin’s much higher cultivation requirements 100.

Purple Cloud Wings

A flying Dou Technique obtained from the Poison Master’s ruins 60.

• Learning it requires painfully opening branch meridians in her back; she faints during the process 60.
• Successfully cultivates the technique with Yan Lin’s guidance 60.
• Initially lacks flight control and crashes into Yan Lin during practice 60.

Other Techniques and Training

• Seven-Colored Poison Scripture: A poison scripture suited to her constitution; also supplies the information through which she identifies the Tribulation Poison Body 60 63.
• Roaring Lion Chant: A sound-wave Dou Technique listed on her attribute panel; no use in battle is documented 63.
• Practical combat training: Receives intensive sparring instruction from Yan Lin, beginning with no combat experience 62.

Equipment / Weapons / Items

• Ruins scrolls — Receives the Seven-Colored Poison Scripture, Purple Cloud Wings, and Roaring Lion Chant from Yan Lin 60.
• Restoration Pill — Receives a fourth-grade pill that heals injuries and restores Dou Qi after learning the Purple Cloud Wings 60.
• Training supplies — Given healing pills and a scroll containing Yan Lin’s cultivation guidance after sparring 62.
• Five-Patterned Purple Gold Card — Given by Yan Lin for personal spending in Black Rock City; she initially declines before accepting 80.

Relationships

• Yan Lin — Master, protector, and romantic interest. His guidance restores her hope of surviving her constitution, but his recruitment and training also serve his hidden goal of copying her traits. She wishes to be more than merely his disciple 50 60 62 63 84.
• Hai Bodong — Supportive elder and additional teacher. Knowing about her poison body, he does not regard her as a bringer of disaster and takes care in instructing her 80.
• Qing Lin — Close friend. They quickly become like sisters after meeting at the Saint King Palace; Qing Lin later helps Yan Lin understand Xiao Yi Xian’s unhappiness 87 88.
• Queen Medusa — Initially a feared figure, later someone whose relationship with Yan Lin causes emotional uncertainty. Medusa learns of Xiao Yi Xian’s potential and permits her accommodation at the Saint King Palace 85 86 88.
• Mr. Yao — Owner of her former workplace. Xiao Yi Xian intervenes to have Yan Lin spare him 52.
• Mu Li — Unwanted suitor who plots to seize her discovered ruins. His surveillance and manipulation provoke her disgust before Yan Lin kills him 57.
• Li Fei — Assistant who betrays her confidence by supplying Mu Li with information about the cave ruin 57.

Notable Quotes

“But once the Tribulation Poison Body erupts, all life within a thousand miles will be destroyed, and it will affect those around me too. Master, you... aren't afraid?” 60

“Other than my parents, you are the person who has treated me best in this world.” 84

Trivia

• Xiao Yi Xian is older than Yan Lin, despite being his disciple; she privately complains that he calls her “Xian'er” so naturally 62.
• She especially enjoys mushrooms. Poisonous varieties offer both a meal and a cultivation benefit through her constitution 76.
