Background / History

Physician in Qingshan Town

Xiao Yi Xian spends many years in Qingshan Town, where she witnesses numerous travelers lose their lives in the Monster Beast Mountain Range. At the Myriad Medicine Pavilion, she treats a steady stream of patients while cultivating at the Dou Zhe realm 17 19.

She meets Bai Xiaoran on the road and invites him to stay at the pavilion, initially mistaking him for a girl. After learning his gender, she remains captivated by his appearance; his medical knowledge and cultivation also earn her respect 17.

Mu Li repeatedly harasses her and attempts to force her into marriage by threatening the pavilion. Bai Xiaoran drives him away. During a later journey into the mountains, she removes venom from Bai Xiaoran's snakebite, and the pair obtain the Seven-Colored Poison Scripture, which she seeks to suppress her unstable constitution 18 19.

When Bai Xiaoran returns injured after killing Mu Li, she treats him and washes his clothes. She subsequently conceals him in a cellar beneath her room during Mu She's search, then relays Mr. Yao's proposal to destroy the Wolf Head Mercenary Group. She joins the resulting night raid 25 26.

Becoming the Heavenly Poison Girl

After leaving Qingshan Town, Xiao Yi Xian travels to the Chu Yun Empire, where poison masters are widespread. A kind couple helps her during an eruption of her poison body, but both die after touching her. Their deaths make her question the value of kindness, while her awakened constitution proves increasingly difficult to suppress 97.

She eventually becomes the Heavenly Poison Girl and leader of the Poison Sect. The sect infiltrates the Chu Yun Imperial Family, reducing it to a tool for controlling the empire 96 97.

Unhappy that Bai Xiaoran intends to marry Yun Yun, she abducts him from his wedding and seals his cultivation to prevent escape. Despite acknowledging that she has committed many bad deeds, she insists that she never intended him harm and now has the strength to protect him 97.

Alliance Against the Ten Thousand Scorpion Sect

When a Chu Yun Imperial Family attacker poisons Bai Xiaoran, Xiao Yi Xian kills the assailant and extracts the poison herself. Bai Xiaoran then explains that acquiring another Heavenly Flame could allow him to help her completely control the Calamity Poison Body 98.

She supplies intelligence for the Jia Ma Empire's surprise attack and agrees to hold back the Ten Thousand Scorpion Sect. Her spies report Xie Biyan's strength, and she reveals that a Soul Hall Protector previously approached her about capturing Bai Xiaoran 99 100.

During the sect's destruction, she kills Xie Shan with a poison needle and activates her Calamity Poison Body against Xie Biyan's Human-Beast Fusion. Her Calamity Poison Blood leaves him fatally poisoned; after Bai Xiaoran helps her evade his final attack, she finishes him with her sword 101.

The Poison Sect subsequently takes control of the Chu Yun Empire. Xiao Yi Xian leaves with Bai Xiaoran, both to remain near him and to benefit from his Heavenly Flames' ability to suppress her constitution 101.

Traveling Companion and Protector

In Black Emperor City, Xiao Yi Xian confronts Blood Demon Old Ghost over threats to Bai Xiaoran. She later reveals her Calamity Poison Body to deter Earth Demon Old Ghost from demanding that Jia Nan Academy surrender them 105 108.

Before their Central Plains journey continues, Bai Xiaoran learns Yao Tianhuo's Heavenly Capital Fire Seal, a method intended to delay her poison body's eruption for three years 111.

She reunites with Bai Xiaoran after a Sandstone Blast separates them, helps repair Tianya City's Space Wormhole, and pilots their ship. After a Space Storm leaves them injured, Han Xue's caravan rescues them 115 116 117.

While assisting the Han family, Xiao Yi Xian kills a Hong family Dou Emperor with one strike and later helps Han Fei defeat Hong Tianxiao. During their subsequent escape from Wind Lightning Pavilion forces, she uses poisonous gas to stall their pursuers and treats Bai Xiaoran's severe injuries afterward 118 123 127 128.

Mastering Her Constitution

While traveling from Starfall Pavilion to meet Bai Xiaoran, Xiao Yi Xian falls into conflict with Ice River Valley, whose valley master collects rare constitutions. Cornered in Luoshen Ravine, she is struck by Ice Venerable Strength; the resulting Profound Ice Qi threatens to erode her body within a month 143 144.

Bai Xiaoran rescues her with support from Xuan Yi and Ye Xinlan, removes the icy energy with Heavenly Flames, and supplies recovery pills. Xiao Yi Xian admits that she ventured out because she missed him and promises not to repeat her reckless behavior 144.

She and Bai Xiaoran defeat a Heavenly Poison Scorpion Dragon Beast to obtain its magical core. After Xuan Yi saves them from Snake Old Man's ambush, the group secures access to the Ye Family's Yang Fire Ancient Altar 145.

At the altar, Xiao Yi Xian endures shattered meridians and an unstable poison-pill formation before her body is repaired and her constitution brought under control. She emerges as a Dou Zun 146 147.

Ice River Valley renews its pursuit. Ice Venerable reveals that his own Calamity Poison Body was acquired later in life and that he wants her innate constitution to compensate for its deficiencies 148.

She continues accompanying Bai Xiaoran through the Pill Domain and remains concerned about Soul Hall activity. With Yao Chen's later assistance, she completely refines her constitution and reaches seven-star Dou Zun 153 186 223.

Personality

Xiao Yi Xian begins as an approachable physician who offers a stranger lodging and worries that conflict with Mu Li could endanger the entire pavilion. Her experiences with the Calamity Poison Body harden her: the couple's accidental deaths undermine her faith in kindness, and she later executes an attacker who threatens Bai Xiaoran without hesitation 17 18 97 98.

Her care for Bai Xiaoran combines loyalty with possessiveness. She shelters him, treats his injuries, and considers unleashing her dangerous constitution to give him a chance to escape. Yet she also abducts him, restrains him against his wishes, and uses medicine to impair his resistance during intimate encounters 26 97 137 145.

She enjoys teasing him about his appearance and becomes jealous of other women seeking his attention. Her mischievousness persists after her rise to power, but she also accepts criticism following her reckless encounter with Ice River Valley and endures extreme pain to gain control over her constitution 19 122 144 146 164.
