Background / History

Little Fairy Doctor was already a close companion of Lu Yu during his dealings with Qing Lin. She supported his decision to take Qing Lin in and later joined him in guiding Qing Lin’s poison use, antidote techniques, and combat development 20 66.

At Jia Nan Academy, she cultivated in the Heavenly Flame Refining Qi Tower while managing medicinal ingredients and sales for Lu Yu’s pill-refining work. Her arena victories earned her the Strong Ranking position of eighty-sixth and the nickname “Heavenly Poison Girl,” a title she disliked 64.

Her cultivation accelerated after Lu Yu supplied poisons, Blood Poison, and support in forming her Pagoda Tower. The completed tower absorbed the Poison Pill that had restricted her Calamity Poison Body, allowing her to control the constitution and cultivate more freely 77 81 84.

Lu Yu later obtained the Netherworld Poison Flame specifically for her. After a two-month refinement in the Netherworld Poison Marsh, she advanced to Dou Huang and gained dark-green flame within her violet eyes 118 119. She subsequently received the Sea Heart Flame and cultivated it alongside the Netherworld Poison Flame 129 142.

Her relationship with Lu Yu develops from mutual trust and cultivation support into an openly affectionate partnership; they spend the night together after a lantern festival and continue cultivating closely afterward 129 136 137.

Appearance

Little Fairy Doctor is frequently described in white robes or a plain white gauze dress, with an ethereal, refined presence. As her strength grows, poison mist and violet light become visible around her.

• Violet or amethyst eyes, which later carry traces of dark-green flame after refining the Netherworld Poison Flame 119.
• Long dark hair; her appearance is compared to a “moon palace fairy” and a white lotus 65 130.
• Pale-purple poison qi that can condense into butterfly-shaped blades 64 65.
• Often carries a medicinal fragrance from handling herbs and preparing medicinal baths 56 150.

Personality

Little Fairy Doctor is gentle, attentive, and generous. She offers medicinal tea to Zi Yan immediately after meeting her, prepares food for companions, and regularly tends to Lu Yu after his exertions 56 77 123.

She is diligent and practical in cultivation. Despite lacking talent as an alchemist, she studies alchemy insights alongside the Seven-Colored Poison Scripture, becoming proficient at processing medicinal herbs and identifying poisonous materials 56 77.

Though usually soft-spoken, she is protective of Lu Yu and can be decisive in danger. She objected to him entering the core of the Netherworld Poison Marsh alone and volunteered her Calamity Poison Body to assist him 118. In battle, her demeanor can become cold and ruthless, as demonstrated when her poison butterflies corrode vegetation and stone at Magic Flame Valley 143.
