Background / History

Little Doctor Immortal worked as a physician and gathered herbs with Myriad Medicine Hall's expedition in the outer Monster Mountain Range. During one such expedition, a Variant He Yuan abducted her after the mercenary captain fled rather than confront the beast. The creature had been secretly controlled by Dai Changsheng as part of his plan to approach her. 132 133

Dai Changsheng killed the He Yuan and presented himself as her rescuer. He recognized the seven-colored mark on her abdomen as evidence of the Poison Body of Calamity, then gave her the Seven-Colored Poison Scripture to explain the condition. Learning that continued contact with poisons would eventually awaken the constitution and lead to her death, she briefly fell into despair. 133

Dai offered to gather the materials needed for the Poison Pill Method—including three Heavenly Flames, Bodhi Body Transformation Saliva, and the core of a seventh-tier Sky Poison Scorpion Dragon Beast—in exchange for her lifelong service. She accepted immediately, reasoning that she owed him her life and would rather become strong enough to control her own fate than remain helpless. She thereafter asked to be called Xian'er. 133

She accompanied Dai Changsheng into the Amethyst Winged Lion King's cave, where she witnessed him effortlessly kill the beast with Infinite Void and Eight Extremes Collapse. Afterward, she relocated with him and Qing Lin to the Snake People's royal city, where Dai provided poisons, cultivation pills, and protection under Queen Medusa's care. 133 136 138

During the war against the Ten Thousand Scorpion Sect, Xie Biyan's Demon Poison Spot was deliberately allowed to strike her. Rather than suffering its fatal effects, she treated its Poison Dou Qi as nourishment; refining it carried her to the Dou Zong realm. 161 166

Dai later acquired the seventh-tier Sky Poison Scorpion Dragon Beast's magic core and brought her to the Ye Family's Yang Fire Ancient Altar. Using three Heavenly Flames, the magic core, and Bodhi Body Transformation Saliva, he helped her condense a poison pill. This removed the Poison Body of Calamity's loss-of-control risk and allowed her to consume poisons freely. 166 167

After the Poison Pill Method succeeded, she cultivated in poison-rich regions such as Luoshen Ravine and the magma sea near the Ancient Emperor Cave Mansion. She later travelled with Dai Changsheng, Qing Lin, and Zi Yan through the Barren Ancient Region in search of the Bodhi Ancient Tree. 167 175 181

Appearance

Little Doctor Immortal is first described in white clothing “as pure as snow” while gathering herbs. By the Luoshen Ravine expedition, she has snow-white hair and wears a purple-and-white gown. 132 166

• A seven-colored line on her abdomen marks her innate Poison Body of Calamity. 133
• Has bright, clear eyes; her expression is repeatedly noted as shifting from fear and despair to determination. 133
• Her hair is snow-white by the time she reaches Luoshen Ravine. 166

Personality

Little Doctor Immortal begins as a compassionate but vulnerable physician, deeply frightened by the prospect of being powerless when attacked. The abduction by the Variant He Yuan becomes the turning point in her outlook: she chooses a dangerous path of cultivation rather than accept a peaceful but defenseless life. 133

She is resolute once she commits to a decision. She accepts Dai Changsheng's terms without bargaining, endures the pain of poison-pill formation, and faces the Sky Poison Scorpion Dragon Beast's leader with open contempt. 133 166 167

Despite her rapid advancement, she remains devoted to Dai Changsheng and maintains close ties with Qing Lin and Zi Yan. She is also capable of calm confidence around poisons that would terrify other cultivators. 138 175 182

Abilities & Skills

Poison Body of Calamity

An innate poisonous constitution that allows its bearer to grow stronger by consuming toxins.

• Poison exposure awakened the constitution and rapidly accelerated her cultivation. 133 160

• Poison that would kill ordinary cultivators can serve as nourishment for her. 160 161
• Her body is so poisonous that microscopic Poisonous Insects die immediately after entering it. 182

Poison Pill Method

A method that condenses all accumulated toxin into a controllable internal poison pill.

• Required three Heavenly Flames, Bodhi Body Transformation Saliva, and a seventh-tier Sky Poison Scorpion Dragon Beast magic core. 133 166
• Dai Changsheng used the three Heavenly Flames to drive her toxins into her abdomen, where the magic core and Bodhi Body Transformation Saliva enabled formation of the pill. 167
• After succeeding, she could devour poisonous substances without fearing that her constitution would lose control. 167

Poison Cultivation and Combat

Little Doctor Immortal turns poisons into cultivation resources and can employ them against hostile poison cultivators.
