Background and History

Ming Detang cover

Gu Xi entered Ming Detang before Xue Nianbing and was placed at the academy through the Sun Moon Royal Family. Jing Hongchen identifies her Bright Phoenix Martial Soul as rare and notes that she is likely connected to Xu Tianran's faction. Xue Nianbing quickly suspects that “Gu Xi” is an assumed identity and considers the possibility that she is Death Douluo Ye Xishui. 355 358

Her first meetings with Xue Nianbing are marked by confrontational banter. She tries to establish seniority over him, but he repeatedly calls her “little sister,” mocks her affiliation with Xu Tianran, and refuses to explain why his body is stronger than hers. Despite her anger, Gu Xi immediately recognizes that he is far more difficult to manipulate than expected. 355 366

Her public profile initially describes a Rank 68 Soul Emperor and Sixth Tier Soul Engineer of approximately Xue Nianbing's apparent age. Meng Hongchen finds it unusual that such an outstanding student is unfamiliar to her. The Gu Xi persona includes a prepared background, lodging, and academy identity, allowing Ye Xishui to maintain the disguise beyond individual encounters. 348 363

After observing Xue Nianbing's extraordinary Soul Rings, Gu Xi consults the Rakshasa Divine Sense about his potential. Its warning that he may soon surpass both her and Long Xiaoyao makes her increasingly anxious to act before his advancement to Soul Saint. 354 366

Mutual deception

Gu Xi approaches Xue Nianbing intending to secure his Deity inheritance and the power of the Golden Ancient Tree. To earn his trust, she presents herself as a covert asset within Xu Tianran's faction who has endured hardship while gathering intelligence on the Holy Spirit Cult. She shares portions of the cult's hierarchy and history while withholding key truths. 367 369 390

Xue Nianbing plays along while privately probing her for information about Ye Xishui, the Holy Spirit Cult, and its former leader. Their repeated dinners, outings, and verbal sparring gradually become more personal, though both initially regard the other as a potential threat. 367 370 371

Her fabricated account claims that Evil Soul Masters murdered her parents because her inherited Bright Phoenix Martial Soul countered them. She says she gained Xu Tianran's trust to investigate the royal family's connection to the cult, while also serving as his concealed preparation against its members. She then claims to seek Ice Snow Palace's assistance in taking revenge. Xue Nianbing recognizes these explanations as an attempt to gain his confidence rather than accepting them as established facts about her past. 360 361

When discussing Ye Xishui's history, Gu Xi favors an account in which the previous cult leader used her to divide Mu En and Long Xiaoyao. She states that Ye Xishui exploited the two men rather than loving them. Her hostility toward Old Ghost Zhongli reflects his attempt to force himself on her; the Rakshasa's intervention prevented the assault, and she subsequently killed him and took control of the cult. Her lingering hatred also contributed to her use of the Zhongli Three Brothers as expendable probes against Xue Nianbing's possible protectors. 361 362

Gu Xi helps Xue Nianbing and Nana attack a Holy Spirit Cult branch, using Bright Star Fire Rain to destroy its assembled Evil Soul Masters before proceeding into the underground facility. Her willingness to eliminate members of her own organization is consistent with her prioritization of personal ambitions over the cult. 370 371

During the academy exchange matches, she reveals a seventh-rank Soul Tool and combines it with her Bright Phoenix abilities, impressing spectators and Jing Hongchen. Xue Nianbing ultimately wins their duel, and she leaves embarrassed and angry after misunderstanding his intentions. 376 377 378

Identity and exposure

Long Xiaoyao recognizes Gu Xi as Ye Xishui after observing her unusual closeness with Xue Nianbing. Gu Xi admits that she possesses Twin Martial Souls, but tells Long Xiaoyao that her relationship with Xue Nianbing is merely an act designed to obtain something from him. 391 392

Her explanation to Long Xiaoyao is also intended to retain his support as a powerful fighter. Despite his devotion, she views their connection primarily in terms of interests, contrasting it with the unfamiliar warmth she later experiences with Xue Nianbing. 383 417

Before her eventual separation from the Rakshasa, Ye Xishui participates in the Holy Spirit Cult's confrontation with Ice Snow Palace. The palace's multiple Limit Douluo and the uncertainty surrounding its hidden master make her unwilling to risk the cult's destruction, and the attacking force retreats after the Snow Empress demonstrates her strength. 394 395

While accompanying Xue Nianbing on a journey ostensibly connected to Soul Ring hunting, Gu Xi's calculated attachment develops into genuine affection. Her conflict intensifies as the Rakshasa Divine Sense urges her to seize Xue Nianbing's inheritance, while she increasingly hesitates to harm him. 424 427 428

The journey includes a search for a Ten Thousand Year Holy Light Spirit Phoenix. Under Gu Xi's guidance, the pair gradually approaches the Evil Demon Forest while the Holy Spirit Cult prepares its arrangements. During this period, Xue Nianbing's cooking, reassurance, and their growing physical closeness deepen her feelings. After a kiss, she seriously asks whether he likes her and insists that he take responsibility for their developing relationship. 416 417 419 420

After the Rakshasa attempts to strike Xue Nianbing, he reveals that he had known she was Ye Xishui from the beginning. The failed scheme leaves Gu Xi severely injured in body and soul. She later awakens in the Ice and Snow Plane, where she recovers and accepts her feelings for him. 429 439

His disclosure that he has always known her identity also causes profound emotional distress: she interprets their shared experiences as possible hypocrisy and feels betrayed despite her own original deception. The ensuing confrontation involves both Ye Xishui and the Rakshasa attacking him. 421 423

Gu Xi's recovery remains incomplete because the Rakshasa retains origin energy taken from her, preventing her from advancing further unless it is returned. The Rakshasa subsequently acts independently while seeking to restore its own strength. 439 440

After the separation, the Rakshasa possesses Death Douluo's body and seeks to restore its power through members of the Holy Spirit Cult, while Gu Xi awakens separately in Xue Nianbing's plane. Gu Xi explains the limitations caused by the division of her soul and body, but shows far less concern about her lost advancement than Xue Nianbing expects. 431 432

Gu Xi ultimately decides to be with Xue Nianbing. He offers her a future place at Ice Snow Palace as either a teacher or student, while still maintaining surveillance due to her past identity and hidden knowledge. 441

She chooses to remain Gu Xi publicly, while accepting that Ye Xishui is also part of her private identity. Rather than seeking revenge against the Rakshasa for taking most of her body's origin, she experiences an unusual sense of peace and regards her former obsession with becoming a god as less important than staying with Xue Nianbing. 433

Return to Ice Snow Palace

Following the conclusion of the exchange program, Gu Xi travels with Xue Nianbing, Juzi, Keke, and Nana to Ice Snow City. Although she and the other newcomers are initially nervous about meeting Xue Nianbing's existing companions, the Snow Empress and Ice Empress receive them amicably. 447 448

Gu Xi participates in the welcoming banquet at Ice Snow Palace alongside Xue Nianbing's other women, formally beginning her life within his household. 448

Before their departure, she initially fears that Xue Nianbing's return to the palace means he will leave her behind. Learning that he intends to take her with him replaces that anxiety with relief. Their approach to Ice Snow City coincides with the arrival of the God Kings of Life and Goodness, prompting Xue Nianbing to stop concealing his identity as palace master. 432 439

The institution that becomes her home is later renamed the Ice Snow Divine Temple after Xue Nianbing completes the unification of the Douluo Continent. 643

Appearance

Gu Xi is a striking woman with golden hair and golden eyes. She is noted to resemble Qian Renxue, Ye Guyi, Jiang Nannan, and Gu Mingli, though each carries a distinct temperament. 523

• Golden hair and golden eyes 523
• A breathtaking smile that can briefly soften her ordinarily cold demeanor 370
• Often presents herself with a proud, composed bearing, especially when maintaining the Gu Xi disguise 365

Personality

Gu Xi is proud, strong-willed, and highly competitive. She dislikes losing control of a conversation, yet Xue Nianbing's taunts repeatedly leave her angry, speechless, or flustered. Her outward poise contrasts sharply with her tendency to react emotionally when he challenges her identity, motives, or inexperience. 355 366 368

As Ye Xishui, she is calculating and willing to deceive, exploit relationships, and make sacrifices for power. Her original pursuit of dual divine positions outweighs her loyalty to the Holy Spirit Cult, which she regards as expendable if it no longer serves her goals. 369 390

Her growing attachment to Xue Nianbing destabilizes that resolve. She begins to value his concern and companionship despite suspecting that his kindness may be partly calculated, and eventually chooses emotional security over her former obsession with godhood. 425 428 441

After arriving at Ice Snow Palace, Gu Xi remains quick to bicker with Xue Nianbing, but accepts her place among the women close to him. 447 448

Xue Nianbing's description of Ye Xishui as both vicious and pitiful briefly touches her long-frozen emotions. His refusal to judge the circumstances he has not personally witnessed causes her to show sincere warmth, although she initially suppresses it in favor of her ambition to obtain the position of Dual God King. 360 362

Following her recovery, she becomes willing to answer his questions honestly and reveals her impaired condition. Her lack of resentment over the stolen origin energy marks a substantial change from her earlier fixation on power: she feels more relaxed than before and places their relationship ahead of further cultivation. 432 433

Abilities & Skills

Bright Phoenix Martial Soul

Gu Xi possesses the rare Bright Phoenix Martial Soul, the same Martial Soul attributed to Yan Shaozhe. Its light-aligned nature is presented as especially effective against Evil Soul Masters. 358 369

• Phoenix Fireline — launches concentrated phoenix fire attacks. 384
• Light Power — employs light-attribute power during combat. 384
• Golden Flame Fire Pillars — summons pillars of golden flame across the battlefield. 384
• She deliberately suppresses her displayed strength to avoid exposing too much of her true power. 384
• Bright Star Fire Rain — her Fourth Soul Skill releases flaming meteors whose golden flames consume the sinister aura of Evil Soul Masters as fuel. It annihilates the assembled Soul Ancestors and Soul Kings at a cult branch. 370
• Phoenix Fireline is identified as her First Soul Skill, while Light Power is her Second Soul Skill. She channels Phoenix Fireline through the Golden Flame Soul Guiding Spear, demonstrating her ability to integrate Martial Soul attacks with Soul Tools. 376
• Her light power significantly suppresses the Great Holy Spirit, reducing his effective strength before their confrontation. 371
• The strength of Bright Star Fire Rain leads Xue Nianbing to suspect that her displayed Soul Ring colors conceal substantially older rings. An all–Ten Thousand Year configuration is his inference rather than a confirmed public reveal. 370

Twin Martial Souls

Gu Xi admits to Long Xiaoyao that she possesses Twin Martial Souls, a secret that helps explain the discrepancy between her assumed identity and her actual capabilities. 391

Her admission also occurs during Long Xiaoyao's direct recognition of her as Ye Xishui. The Bright Phoenix is the Martial Soul openly used by her Gu Xi persona. 383

Soul Engineering

Gu Xi is a Seventh Rank Soul Engineer, a qualification she conceals until her exchange match with Xue Nianbing. 384

• Uses high-level Soul Tools in direct combat. 384
• Her Soul Engineer rank and hidden strength lead Jing Hongchen to consider her a genius potentially comparable to Xue Nianbing. 384
• Xue Nianbing considers her to possess knowledge comparable to that of a pseudo-tenth-rank Soul Engineer, making her potentially valuable to Ice Snow Palace. 441
• Her initial academy profile lists her as a Sixth Tier Soul Engineer. Jing Hongchen interprets her later seventh-rank reveal as an advancement she has not formally submitted for assessment, though her concealed identity complicates that public interpretation. 348 376
• As Ye Xishui, she already possesses Rank 9 Soul Engineering expertise and numerous Level 9 Soul Tools, which Xue Nianbing considers a major reason to be wary of her. 350
• Her retained pseudo-tenth-rank technical knowledge is explicitly cited when Xue Nianbing offers her a teaching or student role after her recovery. It does not establish a newly awarded tenth-rank qualification. 433

Spiritual Power and Rakshasa Influence

Gu Xi possesses spiritual power at the Limit Douluo level, allowing her to function within conditions that would overwhelm ordinary Soul Masters. 385

• Her mind formerly contained the Rakshasa Divine Sense, which pressured and manipulated her toward obtaining Xue Nianbing's inheritance. 425 428
• The Rakshasa's interference contributes to Gu Xi's internal conflict and later leaves her soul and body divided. 428 440
• She cannot progress further unless the Rakshasa returns the origin energy taken from her. 440
• After Gu Xi's recovery, the Rakshasa acts independently to restore its own strength. 439
• Even her Limit Douluo-level spiritual power only allows her to perceive a few meters through the obscuring field used by Xue Nianbing during their duel. 377
• As her emotional attachment develops, she becomes less able to perceive the Rakshasa Divine Sense's private thoughts. The Rakshasa secretly intends to exploit her feelings and use her body for its own rebirth. 417
• The separation leaves the Rakshasa possessing Death Douluo's body while Gu Xi recovers independently in the Ice and Snow Plane. Most of her body's origin remains with the Rakshasa. 431 432 433

Equipment

• Golden Flame Soul Guiding Spear — a seventh-rank Soul Tool used in her duel against Xue Nianbing. 384
• Soundproofing Soul Tool — isolates her private conversation with Xue Nianbing while she presents her fabricated background and motives. 360
• Level 9 Soul Tools — associated with her original identity as Ye Xishui and considered part of her concealed combat threat before her separation from the Rakshasa. 350

Relationships

• Xue Nianbing — Initially targets him for his Deity inheritance while he covertly investigates her identity. Their mutual manipulation develops into genuine affection, and Gu Xi ultimately chooses to remain with him at Ice Snow Palace. After recovering, she is willing to disclose what she knows and accepts his offer to take her home with him, although he continues to monitor her. 371 429 432 433 441 447 448
• Rakshasa Divine Sense — An intrusive divine presence formerly within her mind that encourages her to seize Xue Nianbing's power and later takes much of her origin energy. It subsequently acts independently in an attempt to restore its strength. Its earlier intervention prevented Old Ghost Zhongli from assaulting her, but it later sought to exploit her attachment to Xue Nianbing for its own rebirth. 362 417 425 428 439 440
• Long Xiaoyao — A former devoted associate who recognizes her true identity as Ye Xishui. Gu Xi reassures him that her apparent intimacy with Xue Nianbing is only an act, despite her developing feelings. She values his usefulness as a fighter but does not experience the same warmth toward him that she feels for Xue Nianbing. He is later slain by Xue Nianbing. 383 391 392 417 591
• Xu Tianran — Gu Xi is associated with his faction under her public identity, though she insists that she is not the same as him and claims to have approached him for her own purposes. As Ye Xishui, she is his adoptive mother; their political relationship is characterized by mutual suspicion rather than complete loyalty. 358 361 366 369
• Nana — Assists Nana against a Holy Spirit Cult branch while Xue Nianbing privately recognizes Gu Xi as Nana's superior within the larger organization. The two later return to Ice Snow Palace in the same group. 377 447
• Juzi and Keke — Travel with Gu Xi and Xue Nianbing to Ice Snow Palace after the exchange program, where they are welcomed alongside her. 447 448
• Snow Empress and Ice Empress — Welcome Gu Xi to Ice Snow Palace and include her in the gathering of Xue Nianbing's companions. Before her change of allegiance, Ye Xishui confronts the palace and recognizes the danger posed by their strength. 394 395 448
• Mu En — Part of Ye Xishui's historical entanglement with the Black-White Twin Saint Dragons. While discussing that history under her Gu Xi identity, she describes him as having recognized the previous cult leader's scheme and withdrawn from it. 361 362
• Old Ghost Zhongli — The former Holy Spirit Cult leader who used Ye Xishui in his schemes and attempted to force himself on her. She killed him and assumed control of the cult, but her hatred of him persisted long afterward. 362
• Jing Hongchen — Knows Gu Xi as a royal-family-backed Ming Detang student and recognizes her apparent talent during the exchange duel. He remains cautious about her connection to Xu Tianran and does not intend to favor or harm her solely on that basis. 350 376
