Background / History

Four years before her introduction, Gu Yuyue had just graduated from the Police Martial Academy when Chen Wu's mother died during the Golden City Beast Tide Disaster. Though unrelated to Chen Wu by blood, Gu Yuyue returned to Jincheng at age twenty-two, joined the police station where their mother had worked, and assumed responsibility for raising him. Her work kept her busy, but she made a point of returning home whenever missions allowed. 20

She had been a peak Rank Eight martial artist upon graduating from the academy. Though she was regarded as a martial prodigy, caring for Chen Wu divided her attention and delayed her advancement toward Rank Six. 21 23

Gu Yuyue primarily specialized in saber techniques after university testing showed greater aptitude for them, though she also minored in halberd techniques inherited from her adoptive mother. Her biological parents left her a longsword, which she later had reforged. 22 23 34

When she discovered Chen Wu's abrupt cultivation growth, she correctly identified the signs of his awakened special physique. She took three months of martial leave to pursue her own Rank Six breakthrough while personally guiding his return to martial arts. 20 21

Chen Wu's rapid mastery of the halberd technique resolved Gu Yuyue's long-held regret over being unable to fully inherit their mother's halberd legacy. The emotional release immediately preceded her breakthrough seclusion. 23 27

After initially opposing Qi Ruyan's effort to recruit Chen Wu for National Martial University, Gu Yuyue relented when he demonstrated both his sixth-turn cultivation and the apparent Heavenly Spirit Sacred Body. She continued to impose training requirements and demanded that he stop concealing major developments from her. 27 28 29

To protect Chen Wu from the consequences of public attention, Gu Yuyue took public credit for the Dragon-Subduing Divine Palm. She later demonstrated all eighteen forms before police officials, donated the technique free of charge, and became acting chief of New An Police District. 35 36 46

Appearance

Gu Yuyue is described as a valiant beauty with fair skin, smooth luminous features, and long, glossy black hair. When first seen at home, she wears her hair tied behind her head while cooking. 20

• Fair, snow-white complexion. 20
• Smooth, luminous facial features and phoenix brows. 20
• Long black hair with a glossy, silky appearance. 20
• Often presents an elegant, composed demeanor, though her martial presence becomes sharp and imposing when instructing Chen Wu. 22

Personality

Gu Yuyue is deeply protective of Chen Wu and treats his safety as her foremost concern. Her fear of losing him stems from their mother's death; she initially planned a safe police-station position for him rather than allowing him to risk a military career. 27 28 50

She balances this protectiveness with warmth and playful familiarity. She cooks for Chen Wu, worries when he fails to contact her, lightly scolds him for hiding things, and frequently banters with him. 20 29 47

Despite her concern, Gu Yuyue recognizes extraordinary talent when she sees it. Chen Wu's halberd talent brings her to tears because it ensures their mother's legacy will have an heir, while his creation of the Dragon-Subduing Divine Palm fills her with pride. 23 35

She is willing to alter her own martial path for Chen Wu's sake. Although she had avoided body-tempering because of its effect on appearance, she chose to cultivate the Golden Bell Shield to become stronger and better protect him. 38 39

Gu Yuyue majored in saber techniques and minored in halberd techniques at university. She learned halberd methods from her adoptive mother, a Rank Six halberd expert. 22 23

• Uses halberd techniques with broad sweeps, long-range offense, close-range defense, and numerous variations. 22

Although her specialization is the saber, Gu Yuyue also possesses a foundation in fist and palm techniques. 22 36

• Learned and performed the Dragon-Subduing Divine Palm before police officials. 36 46
• Publicly claimed authorship of the eighteen-form technique to conceal Chen Wu's exceptional talent. 35 36

• Reached the fifth stage, Gathered Force Rebound, which produces stronger counterforce against stronger blunt-weapon attacks. 41
• Reached the sixth stage, allowing Golden Bell Force to form a protective bell outside her body. 47
• Her cultivation of the art helped open the way toward Spirit Refining, where she had previously been unable to make progress. 41
• Entered Turtle Breath after fusing her internal energy with Golden Bell Force, accelerating her body-tempering advancement. 39

• Reforged longsword — A weapon left by her biological parents and reforged through Forge Master Mountain. 34
• Training heavy saber and halberd — Secret-realm mineral weapons weighing approximately twenty and thirty kilograms respectively, used to teach and train Chen Wu. 23

Relationships

• Chen Wu — Her younger brother, though not related by blood. Gu Yuyue raised him after their mother's death, guides his cultivation, and is fiercely protective of his future. 20 21 27
• Qi Ruyan — Her longtime best friend and high-school classmate. Their friendship is strained when Qi Ruyan tries to recruit Chen Wu into National Martial University, but they later cooperate to train and support him. 24 27 32
• Chen Wu's mother — Gu Yuyue's adoptive mother and halberd instructor. Her death in the beast tide deeply shaped Gu Yuyue's protectiveness toward Chen Wu. 23 27
• Gu Yuyue's biological parents — Left her a longsword, which she later had reforged. 34
