Background / History

Holy Capital training and manipulated memories

Cui Xiya studied in the Holy Capital and trained to become a Paladin’s Light Fairy partner. Initially, she remembered deliberately failing her final assessment so she could escape and expose the Radiant Goddess’s true nature, although the relevant memories were missing 352.

After recovering her memories, she revealed that Saintess Istil had arranged her rejection, altered her recollections, and sent her to the Golden Commerce Guild. Cui Xiya had still been a devout believer when she accepted the Saintess’s instructions. She did not know why Istil had arranged her sale 737.

Purchase, reconstruction, and recruitment

Yang Yi purchased Cui Xiya while she was severely injured and suffering from damaged memory. Her body was shrinking, and confinement in a black bag led to a near-fatal incident in which her own saliva dissolved much of what remained of her body 341 342.

Yang Yi reconstructed her with the Limb Restoration Spell, incorporating fish bones and other materials. The repairs also improved her damaged memory. On awakening, she offered her knowledge and service in exchange for help returning to the Sea of Miracles; Yang Yi registered her as a Nightmare Star crewmate and subsequently appointed her Navigation Consultant 343 344 345.

Cui Xiya remembered her rescue as a dream in which the Great Blasphemer delivered her from death. She became his fervent follower without recognizing Yang Yi as the being she worshipped, instead interpreting his transformations as signs that he was another blessed believer 349 363 364.

Appearance

Cui Xiya is a tiny, luminous, winged fairy whose body changes substantially through reconstruction, disease, and muscle implantation 343 346 780.

• Initial reconstructed form: White skin with small silver-gray patches resembling pale tattoos, tiny fish scales beneath her left eye, and two additional pairs of silver-gray, fish-scaled wings with multicolored halos 343.
• Early measurements: 14 cm tall and 250 g when first examined through her crew panel 346.
• Fluctuating wings: Sometimes has only one or two pairs rather than three; the reduced-wing states coincide with noticeably diminished judgment or reliability 348 350 383 389.
• Post-implantation form: 18 cm tall and 1,882 g, with dimmer light, a brown tint to her formerly porcelain-white skin, visible abdominal definition, and muscular limbs 780.
• Variable build: Repeatedly gains weight through overeating and loses it through exercise and a Holy Water diet. Later weight gain can also support her training, and Big Eater turns food into a source of attribute experience 408 493 799 854.
• Giant form: An upgraded imitation scepter allows her to grow nearly thirty meters tall 1017.

Personality

Cui Xiya is proud of her intelligence and readily advertises herself as “the Learned.” Her curiosity and exceptional learning ability let her quickly acquire practical skills, including shooting and fishing. However, her enthusiasm commonly fades after a few days, leaving her broadly knowledgeable without consistent dedication to a single pursuit 350 374 391 395.

Her lack of physical strength genuinely frustrates her. Admiration for Yang Yi’s muscular physique motivates her to exercise, pursue strength enhancements, and eventually design a mech modeled on him. This ambition sometimes produces sustained effort that contrasts with her usual habit of working in short bursts 493 642.

She is gluttonous, argumentative, and boastful, but also protective of her companions. Despite constant quarrels with Cui Bisi, she shields her during dangerous battles and celebrates her advancement to Archmage as enthusiastically as if it were her own 748 836 843 1012.

Her early terror of witches makes Su Na’s examinations especially distressing. Her later loyalty to Yang Yi is much stronger: she trusts his instructions despite her doubts and becomes sufficiently ruthless to suggest killing a possible witness to protect the group 348 477 754.

Abilities & Skills

Light, Regeneration, and Aquatic Movement

Her modified fairy body combines illumination, exceptional vitality, and efficient underwater movement 346 780.

• Natural radiance: Emits light capable of dispelling darkness in the Sea of No Light 780.
• Regeneration: Can recover provided her head and wings are not destroyed. Su Na’s early examination leaves no lasting scars despite tissue sampling 348 780.
• Aquatic Wings: Grants all attributes +2, reduces swimming stamina consumption by 75%, and allows fish-like underwater movement 780.
• Underwater speech and swimming: Can speak underwater and keep pace with Yang Yi during a roughly ten-kilometer pursuit 368.

Decomposition and Craftsmanship

Cui Xiya secretes saliva that breaks down suitable substances, using it alongside miniature tools for precision fabrication 346 593.

• Initially produces Fine-quality equipment slowly; a human-sized helmet would take about half a month and would lack a blessing 350.
• Makes miniature exercise equipment, weapons, tailored clothing, and valuable Great Blasphemer statues 362 493.
• Later modifies Treasured equipment and completes an Exceptional Darkness Bodysuit, incorporating a Mid-Tier Abyss Soulstone 593.
• Installs cables and tiny components inside confined hull spaces, contributing to the Long-Legged’s outer armor installation 608.
• Her reconstructed Light Fairy variant is explicitly unable to dissolve its own body, unlike the earlier self-decomposition incident 342 346.

Memory and Learning

Memory Palace+ gives her exceptional memory and learning ability, near-perfect retention of memorized information, and Perception +3 642.

• Learns marksmanship rapidly enough to hit distant glowing targets after one night of practice 391.
• Understands the Sea of No Light’s shifting geography and explains the sacrifice, inquiry, and guidance stages of heading rituals 350.
• Teaches Cui Bisi model-making at Yang Yi’s request 790.

Martial Instruction and Marksmanship

Cui Xiya knows orthodox Paladin swordsmanship and can demonstrate correct technique even when her original body lacks the strength to apply it effectively 352 355.

• Teaches Yang Yi greatsword handling and polearm thrusting 355 404.
• Performs a textbook Supreme Holy Slash through her mech 665.
• Initially counters revolver recoil by flying toward her target before firing; the enhanced weapon later removes almost all recoil in its normal mode 374 391.
• Her technical knowledge does not guarantee victory: the upgraded Old Captain decisively defeats her in sparring 1013 1014.

Magic and Heretical Faith

Her recorded spells include Light Spell, Healing of the Flame!, and Fire Makes Me Happy! 780.

• Learns Fire Makes Me Happy! from the Book of Scorch (Middle) with help from the Fishman Great Sage’s Hunt effect 581.
• Seeks Cui Bisi’s instruction in Greater Light Spell, although the supplied scene does not confirm successful mastery 800.
• Heretical Fanatic: Grants Spirit +4 and causes frenzy at low Sanity. Praising the object of her faith increases resistance to Sanity damage 780.

Limit Overload

Limit Overload temporarily pushes her modified body beyond its normal performance 780.

• Raises every attribute except Spirit by 3 for fifteen minutes.
• Causes a rapid increase in body temperature.
• Afterward, two pairs of wings fall off and every attribute except Spirit is reduced by 5 during the weakened state.

Command and Intelligence Gathering

• Acting captain: Coordinates the Nightmare Star’s defense against Fishmen and uses Kurich’s remains to frighten the attackers into retreat 538.
• Emergency helmswoman: Keeps the ship under control in violent winds until nearly exhausting her stamina 692.
• Fairy intelligence network: Becomes the local Light Fairies’ leader in the Holy Capital and uses their connections to investigate player residences and search for Zhou Dai 750.

Equipment / Weapons / Items

• Pocket Money Pouch / Money Bag — A spatial storage item worn like a backpack. Holds money, clothing, food, books, weapons, and eventually her mech 349 377 665.
• Miniature Revolver → Silence or Burst — Enhanced with a Low-Tier Artisan Inscribed Stone into a Treasured weapon just over three centimeters long 391.
  • Six-round capacity; automatically reloads in one minute.
  • Normal shots are almost silent and effectively recoilless.
  • Once-daily Burst Mode doubles each successive shot’s power, noise, and recoil; afterward, the barrel requires twenty-four hours to cool.
• Miniature greatswords — Progresses from Fine darts used as teaching swords to a 22 cm, 1,020 g replica of Broken Iron. Later receives a Hero-level greatsword commissioned by Yang Yi 377 493 1013.
• Rusty Long-Legged Sardine Pistol — Given to her by Yang Yi and subsequently modified into a leaping mechanical mount; she feeds it small metal parts as ammunition 513 538.
• Seven-Colored Hummingbird — A firearm used during the Fishman assault 538.
• Darkness Bodysuit — Self-made Exceptional equipment that conceals her natural glow and enables invisibility. Yang Yi’s Three Eyes can still see her 593.
• Twisted Mech — A Hero-quality, flesh-and-machinery creation based on her design 665.
  • Connects to her through piercing tentacles and follows her bodily movements.
  • Flies, wields a flaming greatsword, and transforms into a giant Long-Legged Sardine.
  • Greatly increases her combat power but drains her stamina.
• Super Great Blasphemer Mech — Used to shelter Cui Bisi and defeat mirror counterparts through chains and the mech’s feeding mechanism 836 838.
• Upgraded imitation Light Fairy scepter — Won from a blind box. Its original imitation form enlarges the user without attribute bonuses; after enhancement, Cui Xiya uses it to grow nearly thirty meters tall 1017.
• New Super Great Blasphemer — The Miracle Processing Factory’s first Master-level item, produced through extensive investment of robots and captured technological armaments 1026.
  • Uses an enormous greatsword, Supreme Holy Slash, and Death Storm.
  • Its cockpit remains vulnerable to infiltration, as Yang Yi demonstrates during their sparring match 1027.
• Two Master-level daggers — Given to her by Yang Yi; each functions as a suitably sized greatsword in her hands 1133.

Relationships

• Yang Yi — Purchaser, rescuer, captain, and eventual physical modifier. She teaches him martial techniques while he funds her talents, supplies her equipment, and helps overcome her racial strength limit. He offers her the First Mate position if she can defeat the Old Captain 343 352 642 780 1027.
• Su Na — Crewmate and examiner whom she initially fears as a witch. They later cooperate on technical work; Cui Xiya also monitors Su Na’s dangerous Sanity decline and shoots Yang Yi’s outer ear to wake him in an emergency 345 348 403 608.
• Xiaoji — Fellow crewmate and combat partner. His underwater warning and fire support assist her successful defense of the Nightmare Star 345 538.
• Cui Bisi — Fellow Light Fairy, rival, and close companion. Their insults mask mutual concern: Cui Xiya protects her in battle, while Cui Bisi rescues her from the white sea and monitors her condition on Sweet Island 735 737 843 1124.
• Saintess Istil — Arranges Cui Xiya’s altered memories and sale, then later occupies her body to communicate with Yang Yi 737.
• Old Captain — Sparring opponent and the benchmark for her promised promotion to First Mate. His decisive victory exposes the gap between her training and practical combat ability 1013 1014 1027.

Story Role / Major Arcs

Cook Island

• Accompanies Yang Yi underwater, detects an acidic stench and human blood, and helps investigate the island’s Great Sea Lung body 377.
• Returns during the Fishman Great Sage confrontation and diverts his attention, giving Yang Yi a crucial opening despite disobeying orders to leave 383.
• Develops her marksmanship but is sent back to the ship before Yang Yi attempts to capture a Great Sea Lung larva 391.

Crystalline Disease and Crystal Island

• Initially reacts to infection by overeating, then resumes weight control after learning treatment may be possible. Early crystallized tissue is cut away and regenerated 408 410.
• Becomes a complete living statue. Yang Yi initially reassures her through private messages, but terminal progression eventually removes even her access to system functions 425 437.
• Is mobile again by Yang Yi’s return after Crystal Island’s destruction; his Maw of Gluttony nearly devours her because consuming Light Fairies can reduce Pollution Depth 455.

Acting Captain and the Fake-Death Incident

• Defends the Nightmare Star while Yang Yi is absent, repelling Fishmen by displaying their former king’s remains 538 575.
• Later appears dead on her crew panel during Su Na’s potion experiment, leading Yang Yi to believe he has consumed her. She is found intact in the Captain’s Quarters and subsequently protests that she is not dead 574 575.

Holy Capital

• Recovers her memories of Istil’s arrangements and reunites with Cui Bisi 735 737.
• Establishes herself as the local Light Fairy leader and gathers intelligence for Yang Yi 750.
• Undergoes muscle implantation and reconstruction, finally breaking through the strength limitation that had defined her original species 779 780.

Mirror Island and Legendary Advancement

• Protects Cui Bisi through the mirror battles; the pair use their mech to overpower mirror versions of themselves 836 838 843.
• Trains toward Fool, advances to Legendary, and tests her rebuilt Master-level mech against Yang Yi. He defeats her by entering its cockpit but acknowledges its combat strength 1012 1026 1027.

Sweet Island and Later Events

• Charges into a flower monster and is swallowed, then cuts and burns her way out in the New Super Great Blasphemer. The crew continues establishing its forward base while Cui Bisi checks her condition 1124.
• During the final battle, opens her damaged mech’s cockpit and urges Cui Bisi inside so they can retreat 1160.
• Later serves as the “King’s envoy,” remaining relatively unaffected by the salt influencing those around her 1205.
• In the extra story, accompanies Cui Bisi and first-grade students to the Homestead’s Deep Space Window and notices Yang Hao’s absence 1221.

Alternate-World Counterpart

• Li Mumu — A counterpart encountered by Yang Yi during his hospital experience. She is an academic prodigy specializing in neurology and mental illness, admired even by Su Na, but careless about everyday matters and personal grooming. She explains that people who cared for Yang Yi during medication were incorporated into his dream world as major characters 1191.
