Appearance

Bi Xiao is described as dainty, naive, pure, and innocent, with almond-shaped eyes and a delicate appearance. 1 15

• Often wears an expression of open curiosity or confusion.
• Her immortal power manifests as azure-green escape light. 8
• When wielding the Dragon-Phoenix Flute, dragon and phoenix phantoms circle around her. 26 27

Personality

Bi Xiao is playful, impatient with long seclusion, and easily excited by new opportunities. She initially treats Lei Xiao with the curiosity of a child, but quickly accepts him as her fourth brother and becomes deeply protective of him. 1 3

Although confident in her own fortune and cultivation, she regularly trusts Lei Xiao's judgment in dangerous or politically uncertain situations, including his decision to avoid King of the East's discourse. 4 8 Her devotion to her sisters is equally strong: she rushes to return when her breakthrough vision reveals Yun Xiao and Qiong Xiao in danger, and she is injured trying to purge the Sha Qi within Qiong Xiao. 13 22

She holds a lasting grudge against Zhao Gongming for preventing her from helping Lei Xiao during his battle with the Innate Yin-Yang Baleful Qi Flood Dragon. 27 28

History

Three Immortal Isles

Bi Xiao takes human form alongside Yun Xiao and Qiong Xiao after completing their tribulation on Three Immortal Isles. When Lei Xiao suddenly appears within the island's intact Innate Great Array and calls himself their younger brother, she is the first to question his identity. 1

Soon afterward, powerful sea-clan cultivators attack the islands in pursuit of presumed innate spiritual treasures. Bi Xiao helps her sisters sustain the Innate Great Array, then grieves when Lei Xiao exhausts himself using Purple Heaven Divine Thunder to save them. 1 2

Journey for the Dragon-Phoenix Flute

After Lei Xiao awakens from his long recovery, Bi Xiao eagerly agrees to leave Three Immortal Isles with him, both to escape the boredom of seclusion and to protect him with her superior cultivation. 3

Three years later, she senses a personal opportunity drawing her southeast. Despite the mist's ability to consume divine sense, she enters the island with Lei Xiao. The illusion traps her for what feels like tens of millions of years and later drives her into the Dragon-Phoenix Battlefield's central killing zone. Lei Xiao saves her at great risk. 4 5 6

Injured but determined to rescue him, Bi Xiao follows the treasure's call to an azure jade flute. The Dragon-Phoenix Flute recognizes her, and she uses it to shatter the illusion realm and recover Lei Xiao. 7

Fire Region and Tongtian's Discipleship

Bi Xiao accompanies Lei Xiao into Tang Valley's Fire Region, using the Dragon-Phoenix Flute against the Fire Demon God's fiery crows before Lei Xiao recognizes that killing them accelerates the entity's revival. 9 10

After a thousand years of refining her flute, she reaches the mid-stage Taiyi Golden Immortal realm. Her breakthrough vision reveals Yun Xiao and Qiong Xiao in danger, prompting her and Lei Xiao to return immediately. 13

Tongtian seeks Bi Xiao as his fated disciple, calling her unusually unlucky after she endured four life-and-death tribulations in only a few hundred years. With Lei Xiao's approval, she becomes Tongtian's personal disciple and then sincerely asks Tongtian to accept Lei Xiao as well. 14 15

Conflict with Zhao Gongming

While Lei Xiao confronts the Innate Yin-Yang Baleful Qi Flood Dragon, Zhao Gongming prevents Bi Xiao from going to his aid. After Lei Xiao returns safely, Bi Xiao confronts Zhao Gongming with the Dragon-Phoenix Flute and remains hostile even after he joins Tongtian's sect as a registered disciple. 27 28

• Tongtian — Her master. He accepts Bi Xiao as a personal disciple and imparts the Nine-Turn Primordial Essence Art. 15 16
