Xiao Feiyu

Biodata

Appearance

Xiao Feiyu appears to be a beautiful young woman around twenty years old, despite possessing the cultivation of a level-97 Super Douluo. Lu Shiyuan describes her as having a gentle, mature, wife-like charm. 3 4

• Often presents a soft smile and an indulgent expression around Lu Shiyuan. 20
• Her lightning manifests as azure-blue currents around her pale fingertips. 15
• Her calm exterior can become openly intimidating when Lu Shiyuan is threatened. 15 23

Personality

Xiao Feiyu is affectionate, teasing, and intensely protective toward Lu Shiyuan. She repeatedly calls him “Xiao Yuan,” rubs his head, and treats him with a familiarity he initially finds suspicious. Her private recollection that she had been willing to sacrifice her life for him in a previous life establishes an attachment she does not initially explain to him. 3 16

As a mentor, she is uncompromising. Her three-month regimen subjected Lu to aura pressure, waterfall training, sparring, lightning stimulation, meditation, and combat instruction; she later allows him to recover naturally from battle wounds so he can learn his physical limits. 4 22 She is also secretive and strategic, withholding major information until Lu becomes strong enough to handle it. 3 21

Outside her circle, Xiao Feiyu can be cold and ruthless. She uses overwhelming force to control dangerous situations, yet does not seek needless slaughter: she heals the Nether Wolf after Lu defeats it and respects his choice to spare it. 6 22

Her protectiveness sometimes conflicts with her commitment to Lu Shiyuan’s independence. When he and Xiao Wu fought Evil Soul Masters during their journey to Suotuo City, she nearly intervened in anger, but accepted Yun Qingluo’s argument that they needed to survive genuine danger themselves. Afterward, the women destroyed the attackers’ stronghold. 46

Despite her confidence in Lu Shiyuan, she is cautious about changes to the future she remembers. She initially welcomes favorable deviations involving Xiao Wu and Spirit Hall, but later worries that even small, uncontrolled changes could undermine a carefully rehearsed long-term plan. Her trust in Lu remains stronger than her trust in herself. 29 49

• Restored the critically injured Nether Wolf after Lu Shiyuan completed his mission, allowing it to leave alive. 22

Combat Instruction

Xiao Feiyu personally shaped Lu Shiyuan’s early cultivation foundation.

• Provided the Lu family’s advanced meditation technique, which improves Soul Power cultivation and tempers the body. 3
• Designed a daily training schedule of at least twelve hours, combining physique tempering, meditation, combat practice, lightning stimulation, and lessons. 4
• Trained Lu through one-sided sparring, contributing to his ability to fight above his apparent cultivation rank. 4 14
• Explained that Soul Ring absorption limits depend on physique, Martial Soul quality, and accumulated Soul Power rather than a universal first-ring limit of 423 years. 3
• Her early lightning tempering helped prepare Lu’s body to withstand the opposing energies of the Ice and Fire Yin Yang Well, where otherwise his meridians would likely have suffered grave injuries. 29
• Explained that Lu’s unusually dense Soul Power and powerful Martial Soul require him to accumulate substantially more Soul Power per level than an ordinary Soul Master, accounting for his slower-than-expected advancement. 59

Knowledge of Lu Shiyuan’s Secrets

Xiao Feiyu knows details that Lu considers impossible for an outsider to know.

• Identified the one-of-a-kind Void-Time Dragon Eyes and Star God Heavenly Orbit immediately. 3
• Knew that Lu receives Soul Rings by completing system missions rather than hunting soul beasts. 3
• Demonstrated unusual understanding of the system’s mission requirements, but refuses to explain the source of her knowledge until Lu is stronger. 21
• Advised Lu to conceal the true name of the Void-Time Dragon Eyes and use “Heterochromatic Twin Eyes” publicly until he became strong enough. 5
• Privately connected the origin of his Martial Soul to an unidentified being, without explaining that connection to him. 59

Previous-Life Knowledge & Long-Term Planning

Xiao Feiyu retains memories of a previous life involving Lu Shiyuan. She and Yun Qingluo also compare present developments with scenes they had previously seen, recognizing that the current course of events is not identical to their expectations. The precise means by which they returned and obtained this knowledge remain unexplained. 3 29 39 49

• Participates in a long-term plan intended to prepare Lu for a future disaster; Yun Qingluo states that they still have more than ten years to prepare during their stay at the Ice and Fire Yin Yang Well. 29
• Warned Lu against eliminating Tang San early because Tang San still had an important use in their plans. 20
• By the return from the Zhu Family visit, recognizes that Lu has formed a theory about her and Yun Qingluo’s origins; he chooses not to demand an explanation. 37
• Knows that excessive intimacy between Lu and the women sharing her circumstances could attract the attention of unidentified dangerous beings before he is ready. She warns that doing so would endanger both him and those connected to him. 65

Immortal Herb & Soul Skill Assessment

Xiao Feiyu possesses knowledge of immortal herbs, Martial Soul evolution, and Soul Skill selection.

• Explained how the ultimate ice attribute of the Profound Frost Condensed-Jade Branch could support Dugu Yan’s evolution from a Jade Phosphor Serpent into an Ice Dragon. 27
• Directed Xiao Wu to Lovesick Heartbreak Red and understood the significance of whether she could claim it. 29
• Helped Yun Qingluo select an area-of-effect control direction for Dugu Yan’s third Soul Ring, then personally accompanied Dugu Yan on the hunt. 30
• Tested Dugu Yan’s Permafrost Prison and judged that its control effect would reliably work against Soul Kings, while its effectiveness against stronger opponents was uncertain. 31
• Recognized the potential synergy between Xiao Wu’s enhanced armor-piercing attacks and Dugu Yan’s control abilities. 31

Equipment / Items

• Lu family meditation technique — Returned to Lu Shiyuan as his inheritance; it is several times more efficient than common methods and also tempers the body. 3
• Carrot-pendant necklace — Given to Xiao Wu; conceals her soul-beast aura and must not be removed. 7
• Dragon-head necklace — Left for Lu Shiyuan; conceals his aura and disguises the color of his Soul Rings. 11
• Soul Tool — Used to store and carry the Lu family meditation technique. 3
• Xiao Wu’s identification papers — Obtained from a Spirit Hall branch during the return to Notting City, allowing Xiao Wu to enroll at Nuoding Academy under a documented human identity. 10

Background & History

Xiao Feiyu arrived in Notting City after sensing the aura of Lu Shiyuan’s Void-Time Dragon Eyes. She introduced herself as his wife, then clarified that she had known his parents, Lu Hao and Chen Yun, and had come to care for him. Although Lu distrusted her, her knowledge of his Twin Martial Souls and system missions forced him to accept that she was connected to his hidden past. 2 3

Before Lu enrolled at Nuoding Academy, Xiao Feiyu took him near the Star Dou Forest for three months of extreme training. The regimen increased his physique to roughly three times that of an ordinary One-Ring Soul Master and prepared him to absorb a thousand-year first Soul Ring. 4 During this period, she identified the newly transformed Xiao Wu as a Hundred-Thousand-Year Soul Beast, but showed no intent to harm her. She later gave Xiao Wu an aura-concealing necklace and supported Lu’s decision to bring her to Notting City. 4 6 7

Xiao Feiyu initially appeared to leave Notting City after Lu began at Nuoding Academy. In reality, she remained nearby as part of a plan to draw out Tang Hao after Lu provoked Tang San. When Tang Hao attacked, she defeated and severely wounded him, warning him never to target Lu again. 8 15 She subsequently departed to handle other affairs, promising to return within a year. 16

Upon returning, Xiao Feiyu accompanied Lu and Xiao Wu to Sunset Forest for their second Soul Ring breakthroughs. She supervised Lu’s solo battle against a three-thousand-year Nether Wolf, ensuring the encounter remained dangerous enough to force genuine growth while retaining the ability to intervene if necessary. 20 21 She later supported Lu’s scheme to approach Dugu Bo and helped establish an alliance centered on treating Dugu Bo and Dugu Yan’s inherited poison. 23 24

Ice and Fire Yin Yang Well

After Yun Qingluo joined the group, Xiao Feiyu traveled with them to Dugu Bo’s herb garden. She helped explain the value of the immortal herb offered to Dugu Yan as Yun Qingluo encouraged Dugu Bo to join their side. 25 27

While Lu endured the spring’s opposing energies, Xiao Feiyu encouraged the worried Xiao Wu to strengthen herself so she could share his future burdens. She then brought Xiao Wu to Lovesick Heartbreak Red, which accepted Xiao Wu after she offered essence blood while thinking of Lu. Xiao Feiyu was surprised by the firmness of Xiao Wu’s devotion. 29

During the group’s stay, Xiao Feiyu and Yun Qingluo discussed changes from the events they remembered. Although the differences were unexplained, Xiao Feiyu regarded the developments involving Xiao Wu and Spirit Hall as favorable. She also helped Dugu Yan obtain her third Soul Ring and assessed the younger women’s new abilities before Lu emerged from the well at level thirty. 29 30 31

Star Luo City

To complete Lu’s mission of fifty consecutive individual Soul Arena victories without attracting prolonged attention in the Heaven Dou Empire, Xiao Feiyu accompanied him, Yun Qingluo, and Xiao Wu to Star Luo City. After their arrival, she took Lu to register at the Great Soul Arena while Yun Qingluo arranged accommodations. 33

When Lu intervened on Zhu Zhuqing’s behalf, Xiao Feiyu accompanied him to the Zhu Family. Her Soul Ring display frightened the Spirit Cat Duke into promising that Zhuqing would no longer be mistreated. On the return journey, Lu indicated that he had guessed something about Xiao Feiyu and Yun Qingluo’s origins, but would focus on becoming stronger rather than prying. Xiao Feiyu also anticipated arranging for Dark Shadow to look after Zhuqing. 36 37

She later watched Lu’s attempt at his fiftieth consecutive victory alongside Xiao Wu and Zhu Zhuqing. After he obtained his third Soul Ring, she supported leaving Star Luo City, noting that an expected short trip had lasted more than half a year and that events had already diverged from her previous life. 37 39

Suotuo City and Shrek Academy

Four years later, Xiao Feiyu told Lu and Xiao Wu that they needed to learn to travel without relying on their protectors. In reality, she and the other women followed them from a distance. They refrained from intervening during the pair’s battles with Evil Soul Masters to preserve the value of the experience, then wiped out the attackers’ stronghold a day later. 40 46

During the journey, the women also encountered Tang Hao again. He fled as soon as he sensed Xiao Feiyu, escaping despite her summoning her Martial Soul to pursue him. After reuniting with Lu in Suotuo City, the group purchased and renovated a large villa near Shrek Academy and moved in before registration began. 46

An account of Ning Fengzhi’s earlier investigation reveals that Xiao Feiyu had discovered and fought Sword Douluo Chen Xin, seriously injuring him. She spared him because she remembered the help he had provided in her previous life, and Ning Fengzhi subsequently abandoned the investigation. At Shrek’s registration, she asked Chen Xin to convey her regards to Ning Fengzhi and announced that they expected to visit Heaven Dou City in about a year, when Ning Rongrong’s Martial Soul would undergo a complete transformation. 49

After Zhao Wuji injured Lu during their sparring match, Xiao Feiyu, Yun Qingluo, and Ye Youying confronted him. Their combined pressure forced him to prostrate himself, but after they withdrew, he discovered that his hidden injuries had healed and his Soul Power had increased to level seventy-seven. Xiao Feiyu described the outcome as their gift of thanks. 57

Protective Restrictions and Later Affairs

When Ye Youying feigned drunkenness to get closer to Lu, Xiao Feiyu and Yun Qingluo confronted her after sending him away. Xiao Feiyu warned that crossing the line could attract dangerous beings’ attention prematurely, and rejected Ye Youying’s assurance that she had only intended to cuddle with him. 65

Xiao Feiyu and Yun Qingluo subsequently remained behind to handle undisclosed matters while Ye Youying accompanied Lu and the Shrek students to the Star Dou Forest. Xiao Feiyu explained that completing these tasks during his absence would make future matters easier. 67 68

After Lu’s return, Xiao Feiyu understood his intentions through a brief exchange of glances and invited Ning Rongrong to speak privately. She told Rongrong that she knew why Ning Fengzhi had sent her to Suotuo City and that Lu was willing to help fulfill the Seven Treasure Glazed Tile Sect’s wish. Their coordination was attributed to the close understanding built over six years together. 92

Relationships

• Lu Shiyuan — Her primary concern; she calls herself his wife, serves as his mentor and protector, and vows to protect him even with her life. Her devotion originates in a previous life, but she restricts intimacy because of the danger posed by unidentified beings. By Chapter 92, their years together allow them to communicate their intentions through glances alone. 3 15 65 92
• Xiao Wu — Protects Xiao Wu’s identity with an aura-concealing necklace and supports her place beside Lu, though her initial statement that Xiao Wu would benefit him remains unexplained. She later directs Xiao Wu toward Lovesick Heartbreak Red, encourages her to become strong enough to support Lu, and privately explains that certain conditions must be met before greater intimacy is possible. 6 7 29 74
• Yun Qingluo — Long-standing associate and fellow Super Douluo; the two share a familiar, playful dynamic and jointly support Lu Shiyuan. They grew up together, can readily sense one another’s aura within Star Luo City, and cooperate in their preparations against the future disaster. 25 29 33
