Background

Dugu Yan is Dugu Bo's granddaughter and his only living relative. Her parents died because of the inherited toxin backlash associated with their martial souls, leaving Dugu Bo to raise and protect her. Before Yu Yuan's intervention, she did not know that the toxin accumulation affecting her light-purple hair also endangered her life. 9 11 12 14

Dugu Bo deliberately made her first two soul rings supportive rather than offensive, fearing that a power-attacker path would worsen the Jade-Scaled Snake martial soul's poison backlash. Dugu Yan nevertheless wished to pursue that path and went to the Great Spirit Arena after arguing with him over the matter. 11 12

Her fight with Yu Yuan exposes the problem. His light-attribute purification temporarily removes toxins from her body, but the disruption of her internal poison balance causes severe pain and martial-soul backlash. She brings him to Dugu Bo for confirmation, where Dugu Bo admits that both of them suffer from their martial souls' toxins. 10 11 12

At the Ice-Fire Yin-Yang Eyes, she consumes an Earth Dragon Golden Melon prepared by Yu Yuan. The herb grants her martial soul a dragon bloodline, enabling its evolution into the Jade-Scaled Dragon and improving her control and tolerance of poison. 15 17 18

Appearance

Dugu Yan is a youthful girl with light-purple hair, jade-green eyes, and a vivid preference for emerald green. Her hair color is an outward sign of the toxins accumulated from her martial soul. 9 11

• Wears a short blue top and skirt, with a snake-shaped hair ornament. 9
• Has jade-green nails and, at times, emerald-green painted toenails. 10 13
• During martial soul possession, snake scales appear near her eyes and across her body, while her legs merge into a snake tail. 10
• Following her martial soul's evolution, her dragonized claws can manifest dark-red and blue coloration associated with fire and frost poison. 20

Personality

Dugu Yan is bold, teasing, and direct. She initiates conversation with Yu Yuan during their first encounter, secretly poisons him while talking, and continues to provoke him after learning he is younger than her. 10 13

Beneath her flirtatious confidence, she is deeply affected by the loss of her parents and by the discovery that her martial soul may lead her down the same path. Her conversation with Yu Yuan about their limited memories of their parents reveals a more vulnerable and empathetic side. 12 14

She is fiercely devoted and possessive toward Yu Yuan, openly declaring him to be her partner when Huo Wu shows interest in him. At the same time, she shows consideration for her close friend Ye Lingling and attempts to include her rather than abandon their friendship. 33 36 37 39

Abilities & Skills

Jade-Scaled Dragon Martial Soul

Dugu Yan's original Jade-Scaled Snake martial soul evolves after she absorbs the Earth Dragon Golden Melon. The new dragon bloodline strengthens her physical qualities and improves her relationship with poison. 15 18

• Her original martial soul's innate poison accumulates inside her body and can harm its wielder. 11 12
• The evolved martial soul improves her control of and tolerance for poison. 15
• Her dragon bloodline resonates with Yu Yuan's higher-ranked dragon bloodline and can be further influenced by it. 18 19 28
• She can still transform her lower body into a tail while using her martial soul. 18 30

Jade-Scaled Red Poison

Her first soul skill is a self-enhancing poison technique. 10

• Classified as one of the supportive poisons selected by Dugu Bo for her early soul rings. 10 12
• Does not affect Yu Yuan due to his powerful constitution and light-attribute purification. 10

Jade-Scaled Blue Poison

Her second soul skill is another self-enhancing poison technique. 10

• Like her first skill, it was chosen to limit the dangers posed by her martial soul's toxin backlash. 10 12
• Yu Yuan clears her poison mist with Solar Flare during their first battle. 10

Fire and Frost Poison

After absorbing medicinal effects from the Ice-Fire Yin-Yang Eyes, Dugu Yan develops resistance to ice and fire and gains poison variations aligned with both elements. 20

• One dragon claw becomes dark red and the other blue. 20
• Can release fire poison and frost poison. 20
• These poison attributes later improve as her bloodline continues to evolve under Yu Yuan's influence. 28

Miasma-Scaled Nether Dragon Spine Bone

Yu Yuan gives Dugu Yan an artificial spine bone created from the Miasma-Scaled Nether Dragon; she absorbs it under his guidance. 30 31

• Absorbs and stores toxins, then condenses and strengthens them for later release. 30
• Creates a poisonous mist by consuming soul power and stored toxins. 30
• The mist can block energy attacks and continuously damage enemies who enter it physically. 30

Equipment / Items

• Portable communication soul tool — a device made through Yu Yuan's concept and Xiao Kong's design; it allows Dugu Yan to contact Yu Yuan within Heaven Dou City, though large-scale battle interference can disrupt it. 40
• Miasma-Scaled Nether Dragon Spine Bone — artificial soul bone compatible with her poison-based martial soul. 30 31

Relationships

• Yu Yuan — Partner. They first clash at the Great Spirit Arena, then grow close after he identifies and begins treating the toxin problem caused by her martial soul. Dugu Yan openly claims him as her partner and later moves in with him. 10 11 14 33 35
• Dugu Bo — Grandfather and guardian. He is highly protective of Dugu Yan, though he eventually accepts Yu Yuan after learning that he can address the family's toxin problem. 12 13 15
• Ye Lingling — Best friend. Dugu Yan values their friendship and personally invites Ye Lingling to become involved in her relationship with Yu Yuan. 35 36 37 39
• Huo Wu — Acquaintance and potential romantic rival. Dugu Yan initially acts possessively when Huo Wu is drawn to Yu Yuan, but later approaches her amicably and helps her acknowledge her feelings. 33 34
• Yu Tianheng — Former pursuer. His attempt to pursue Dugu Yan ends after he learns that she is serious about Yu Yuan. 39 40
