Background

Di Qiuyan grew up beneath the skylight of an underground processing workshop in Yongchang Circuit, where medical equipment and discarded Pathogenized Objects were handled. Her mother, Di Wen, suffered from Alzheimer's disease, and Qiuyan's need to secure treatment heavily shaped her pursuit of status and money. 333 342

Zhong Panxi discovered Di Qiuyan and supplied the resources that enabled her rise into the Seven Xuanyuan Stars. In return, Qiuyan became one of Zhong Panxi's Eye Secret Guards and treated the councilwoman as an unquestionable patron despite privately fearing her. 257 292 320 358

Before publicly entering the Great Capital, Di Qiuyan worked with Xia Yu in the plot intended to lure and kill Chen Chaosheng in Blue Stone Town. She later concealed herself as Yan Qiu, using one of Xia Yu's skins to stay near Zhou Zhi and exploit his connection to Qi Chongxiao. 93 165 333

Appearance

Di Qiuyan is repeatedly described as a petite, exceptionally beautiful young woman with a cold, moonlit presence that keeps others at a distance. Her most recognizable feature is a small beauty mark below the outer corner of her right eye. 125 126 165

• Dark crescent-shaped brows and star-bright eyes. 93
• A beauty mark on the right side of her face. 126 165
• Frequently carries herself with immaculate posture, restrained movements, and formal manners. 125 260
• Wears fitted Plague Armor and uses a cane-like blade in battle. 256 537
• Her hair became white after her later rise in power. 758 773
• Used Xia Yu's skin to appear as Yan Qiu, a seemingly ordinary young girl with a markedly different demeanor. 165

Personality

Di Qiuyan cultivated the public image of an aloof, ascetic “ice beauty” devoted entirely to Plague Extermination Art. The persona began as a defense mechanism: she believed that speaking less, making fewer mistakes, and appearing untouchable could protect the self-respect of an ordinary girl from a poor background. 127 319 497

Behind that façade, Qiuyan is emotional, anxious about gain and loss, fond of novels and dramas, and deeply concerned with money, her mother, and Zhou Zhi. Her Yan Qiu identity allowed these traits to surface openly. 164 213 249 479 508

Her fear of losing Zhou Zhi briefly prevented her from advancing, even though her Technique Domain Prototype and mantra were considered exceptional. She eventually overcame this stagnation through blood-arts cultivation and the support of Zhou Zhi and An Zhiwo. 572 674

After Zhong Panxi's death and Zhou Zhi's apparent death, Qiuyan became notably colder and more revenge-driven. Even so, she remained protective of Di Wen and later carried Moonlight Castle's responsibilities for two decades. 755 783 1119

Abilities & Skills

Ophthalmology Plague Extermination Arts

Di Qiuyan is an optometry prodigy whose combat style specializes in precise, long-range ophthalmological arts and visual manipulation. Her spiritual power can evade ordinary detection. 225

• Sightline Bullets — Fires attacks through her line of sight; she used it against Chen Chaosheng and Zuo Mi. 268 330
• Complete Visual Field — Expands her field of vision and enables long-range observation. 335 480
• Ray Dissolution and Optical Severance — Advanced ophthalmological techniques she had mastered by the Heavenly Chief Hospital incident. 335
• Vision Obscuration — Conceals herself and another person from surrounding observers. 496
• Femtosecond — A sword technique powerful enough that later opponents could not withstand a single move from it. 480
• Concealment — Her eyes can refract light and obscure her presence from others. 165

True Shadow Style and Body Control

Di Qiuyan trained in Jiang Fanzhen's True Shadow Style and developed her amygdala through Heavenly Chief Hospital's mental-training program. Her body-control technique resembles Shadow-Torturing Style but is more advanced. 319 322 335

• Uses spiraling muscular force and instantaneous physical control in close combat. 319
• Maintained formidable combat ability even while inhabiting Zhou Zhi's body during the Personality Riot. 340 341
• Suppressed Zuo Mi and other severely ill patients through superior strength and technique. 330 331
• Her mental fortification reinforced her belief that the mind governs the body. 319

Blood Arts and Human Dragon Domain

After leaving Zhong Panxi's control, Di Qiuyan received intensive blood-arts training and resources from An Zhiwo. This cultivation led to her Lead Surgeon breakthrough and eventual Human Dragon ascension. 674 755 758

• Possesses a Technique Domain Prototype and a mantra regarded as top-tier foundations for advancement. 572
• Absorbed the Thousand-Eyed Ephemeral Flower, which was completely compatible with her and continuously supplied spiritual power. 755
• Can deploy her Human Dragon technique domain to isolate targets, as she did to Zhou Zhi and Beigong Dongzhi. 785
• Her rise to Human Dragon made her a threat even to established Xuanyuan figures and the Fallen Cult's representatives. 758

Disease Transformations

Di Qiuyan suppresses residual disease transformations caused by her battles and advancement.

• Hyperuricemia
• Glaucoma, which significantly restricts her ophthalmological Plague Extermination Arts. 783

Equipment

• First Quarter Moon — Her Plague-Slaying Blade during the Heavenly Chief Hospital incident and later one of the two blades she carried. 341 360
• Moon of That Time — Cane-like Plague-Slaying Blade used against Chen Chaosheng. 268 360
• Moonlit Beauty — Named Blade wielded during her later years as a Human Dragon and Moonlight Castle's leader. 758 784 1119
• Blood Prison Codex — Half of the codex was carried at her waist following Zhong Panxi's death. 755
• Xia Yu's skin — Used to maintain the Yan Qiu disguise; unlike complete skin grafting, it could not reproduce another person's aura or spiritual power. 165

Relationships

• Zhou Zhi — Initially met while he was disguised as Chen Chaosheng; she later lived beside him as Yan Qiu, developed romantic feelings for him, and repeatedly chose him over Zhong Panxi's demands. They reunited after his apparent death and remained close decades later. 126 165 563 784 1121
• Di Wen — Her mother. Di Wen's Alzheimer's disease and safety are central to Qiuyan's motivations and vulnerabilities. 333 483 550 749
• Zhong Panxi — Former sponsor, patron, and master of the Eye Secret Guards. Zhong provided Qiuyan's resources and status, but later sought to possess her body to evade death. 257 292 550
• An Zhiwo / Lan Xin — Mentor in blood arts who identified Qiuyan's fear as the obstacle to her advancement and later supported her cultivation. 572 674 755
• Ji Xiaohan — Fellow Seven Star and academy teammate. He has feelings for Qiuyan, while she generally remains distant; they later defend Moonlight Castle together. 225 248 1119
• Wan Chaohu — Long-term ally and co-leader at Moonlight Castle. The two developed seamless trust while surviving and leading Wanderers after Zhou Zhi's disappearance. 1118 1119
• Beigong Dongzhi — Rival and occasional ally. Qiuyan lost to her in the academy competition, later offered guidance toward Human Dragon advancement, and clashed with her over Zhou Zhi's memorial. 259 783 784
• Zhe Xiu — Fellow Eye Secret Guard whose jealousy and obsession with Qiuyan culminated in an attempt on Qiuyan's life. 282 749
• Xia Yu — Partnered with Qiuyan in the planned ambush of Chen Chaosheng and provided the skin used for the Yan Qiu disguise. 165 333
