Background / History

Qingshan Town and Apprenticeship

Xiao Yi Xian's lifelong ambition is to become an alchemist, although she also possesses exceptional talent for preparing poisons. In Qingshan Town, she uses self-developed poisons to fend off mercenaries who attempt to take advantage of her 433.

While Gu He stays at the Myriad Medicine Pavilion estate, she eagerly agrees to guide him into the Monster Beast Mountain Range to gather herbs. She subsequently performs the formal ritual of accepting him as her master 668 669.

During a cave exploration with Gu He, she recognizes rare medicinal plants, including Ice Spirit Flame Grass. Their discoveries include the Seven-Colored Poison Scripture, which she later studies to identify her Calamity Poison Body 472 433.

Accepting the Calamity Poison Body

The scripture initially frightens her: she fears that awakening her physique will make her an outcast and force her to leave Gu He's side. He reassures her that he already knew about her condition and teaches her the Poison Devouring Pill Condensing Art to control its drawbacks 839.

Determined not to disappoint him, she chooses to awaken the physique by consuming Purple Heart Orchid Grass. Gu He monitors her with soul power and checks on her after she loses consciousness 403.

Appearance

• White clothing: Appears dressed in white when greeting Gu He and emerging from poisonous water 423 362.
• Physique marking: The Calamity Poison Body is identified by a hidden seven-colored line on the lower abdomen. According to the Seven-Colored Poison Scripture, it lengthens as poison power accumulates 433.
• Concealed identity: Uses a black-robed, hat-wearing disguise during her activities in the Cloud Mist Empire and at the Alchemist Convention 297 392.

Personality

Xiao Yi Xian is lively and affectionate around Gu He, but unusually resolute when her training demands pain or danger. Daily poison consumption strengthens her endurance, and witnessing Liu Ling's painful training motivates her to work harder rather than rely solely on her superior physique 90 508 839.

Her loyalty to Gu He outweighs the attraction of a Saint's mentorship. She refuses to become Duan Tiancan's disciple even while agreeing to accept his inheritance. After experiencing numerous battles and witnessing mass death, she is no longer frightened by Gu He's soul-devouring methods 722 113.

She is merciless toward people attempting to kill her, yet caring toward her companions. She comforts Little Silver after a dangerous cultivation session and gives Nalan Yanran protective medicines before her travels 297 362 195.

• Adapts to the Netherworld Poison Fire when the protection of her Blood Lotus Pill begins to fail 725.
• Without control, leaves her body poisonous and risks harming people around her 707.

• Draws released black poison gas back into her body 807.
• Forms a black pill within her Dou Qi vortex, where additional poison gas continues to accumulate 807.

• Burns and poisons the Four-Winged Heavenly Poison Scorpion, destroying its wings and ultimately killing it 799 781.
• Expands to thirty feet during the battle with Xiao Yan 556.
