Background / History

Physician of Green Mountain Town

Xiao Yi Xian became a respected physician in Green Mountain Town, where injured people sought her gentle care and medical expertise. She dreamed of becoming an alchemist and regularly sought instruction from visiting practitioners, but her attributes were unsuitable for pill refinement 15.

She met Gu Fei while working at the Ten Thousand Medicines Shop. His identification of Blood Lotus Essence impressed her, and learning that he was an alchemist prompted her to invite him on a herb-gathering expedition. That evening, she brought him dinner and her annotated medical books to ask for guidance 15 16.

Betrayal and Departure

During the expedition, Mu Li followed her to obtain treasure she had discovered beneath a cliff. His knowledge exposed the betrayal of her assistant and confidante, Li Fei. Gu Fei refused Mu Li’s offer to divide the treasure, protected Xiao Yi Xian, and killed him when he attacked 18 19.

Xiao Yi Xian then asked Gu Fei to help retrieve the cliffside treasures. Among them was the Seven-Colored Poison Scripture, which revealed that she possessed the Woeful Poison Body 19 20 22.

Back in town, Boss Yao confined and interrogated her about the treasure, while Mu She sought revenge for his son’s death. Gu Fei killed both men. Recognizing that she could no longer safely resume her former life, Xiao Yi Xian left for a secluded Small Mountain Valley she had discovered, accompanied by Gu Fei 23 24.

Controlling the Woeful Poison Body

In the valley, Xiao Yi Xian activated her constitution but consumed too much poison and remained unconscious for three days. After waking, she feared that Gu Fei would reject her or suffer from contact with her poison. His acceptance reassured her, although she continued avoiding unnecessary physical contact out of concern for others 24 26.

She later left the valley with Gu Fei and grew close to Qing Lin, whose feared bloodline reminded her of her own circumstances. When she disclosed her constitution to Qing Lin, Gu Fei announced that he could resolve its hidden danger 36 44 45.

After gathering the necessary materials, Gu Fei performed the Poison Pill Method at the Ye Family’s Yang Fire Ancient Altar. Xiao Yi Xian successfully drew her poison energy into the condensed pill, gaining complete control of her constitution. Their relationship became explicitly romantic following their time at the altar 79 80 82.

Marriage and Family Life

In the Gu Realm, Xun’er attempted to undermine Xiao Yi Xian by presenting her former marriage to Gu Fei as an ongoing claim. Xiao Yi Xian briefly feared that she was “the other woman,” until Gu Fei confirmed that the divorce was final. He also defended his intention to marry her before the clan elders, securing his grandfather Gu Lie’s support despite concerns about bloodline 108 109.

Xiao Yi Xian was unsettled by news of a proposed Yan Clan marriage for Gu Fei, but his reassurance steadied her. She later welcomed Cai’er into their household and became friendly with her. Gu Fei discovered Xiao Yi Xian’s pregnancy through his soul force 118 119 128.

After becoming a mother, Xiao Yi Xian wanted to show Xiao Xianle the Small Mountain Valley associated with her early bond with Gu Fei. She chose to remain there with her young daughter rather than continue long-distance travel. Later, she lived in the Gu Realm and reunited joyfully with Gu Fei after his two-year absence 131 134 183.

Appearance

• Hair and eyes: Purple hair and violet eyes 15.
• Build: Slender and graceful, with an exceptionally narrow, willow-like waist 15 107.
• Early clothing: A pale white dress secured with a green sash 15.
• Bearing: A gentle smile and fresh, ethereal air distinguish her appearance 15.
• Constitution marker: The Woeful Poison Body is identified by a faint seven-colored line on the lower abdomen, which lengthens as poison energy accumulates 26.

Personality

Xiao Yi Xian is gentle, compassionate, and deeply invested in medicine. She finds persistent wealthy suitors irritating but struggles to reject them harshly. Her carefully maintained, extensively annotated books show her diligence, while her excitement at herb-rich locations reflects how strongly medicinal study absorbs her attention 15 16 17.

She is also prone to pessimism and overthinking. Waiting alone for Gu Fei leads her to imagine abandonment, while her constitution makes her fear rejection and the possibility of harming those she loves. Her initial reluctance to touch Qing Lin stems from this concern, not dislike 26 35 45.

As she becomes comfortable with Gu Fei, she grows more cheerful and openly expressive. She can be jealous—pulling him away from students admiring women and questioning Cao Ying’s warm greeting—but ultimately chooses to trust him 42 67 90.

Her desire to grow stronger sometimes exceeds her patience. Even after gaining control of her poison body, she pushes herself with excessive toxins and experiences pain while converting them 69 95.
