Background / History

Family and Congenital Poison

Dugu Yan was poisoned before birth and lived for years under the threat of an early death. The condition was difficult for others to detect, and even Ye Lingling did not know about it until Dugu Yan asked whether her purification ability could treat poison 47.

Her parents had already died from poisoning. Dugu Bo blamed his pioneering poison-focused cultivation path for the harm suffered by his family. As his own poisoning worsened, he worried about who would protect his granddaughter after his death and sought additional backers for her 48 49 53.

Academy Life

Ling Yu first notices a purple-haired girl he suspects is Dugu Yan in poisonous substance identification class. Shortly afterward, Dugu Bo appears with her during the academy’s discussions about the Heaven Dou Secret Medicine. By the end of term, she ranks seventh among Heaven Dou Grade students 18 19 26.

Xue Ye later proposes an engagement between Dugu Yan and Crown Prince Xue Qinghe, the identity used by Qian Renxue. Xue Xing objects that the Dugu Family’s inherited Jade Phosphorous Serpent Martial Soul could replace the imperial family’s inherited Martial Soul, stopping the proposal. No engagement is established 31.

Dugu Yan recognizes Ye Lingling’s interest in Ling Yu and playfully tests her reaction. She then directly asks Ling Yu to become friends, begins bringing Ye Lingling to sit with him in compulsory classes, and joins their meals. Both girls subsequently help him test his Ring Fusion talent 39 40 42.

Sunset Forest Expedition

Dugu Yan accompanies Ye Lingling, Ling Yu, Ye Yilan, and Su Yao into Sunset Forest to find Ye Lingling’s third Soul Ring. During the journey, her teasing gives way to keen interest when Ling Yu explains his theories about Soul Skill acquisition 43 44.

When the group encounters a Glazed Deer, Ling Yu uses Dugu Yan’s Soul Power through Ring Fusion to help Ye Lingling overcome its influence and kill it. Dugu Yan then spreads poison around Ye Yilan’s bamboo defenses while the group withstands attacks from surrounding Soul Beasts. The attackers disperse after eight hours 45.

After learning how well the deer suits Ye Lingling, Dugu Yan persuades Ling Yu to help select her future Soul Rings. When Ye Lingling manifests an eye-shaped External Soul Bone, Dugu Yan swears a Martial Soul Oath to protect the secret rather than seek the treasure for herself 46.

Purification and the Dugu Family’s Recovery

Ye Lingling’s new Light of Purification removes much of Dugu Yan’s congenital poison in its first treatment. The green coloration of Dugu Yan’s fingernails fades, and her relief turns to concern when she sees how much Soul Power the treatment has cost her friend 47.

Back at the Dugu estate, Dugu Bo immediately notices the improvement. Dugu Yan attributes the purification to Ye Lingling’s unusual talent and Soul Ring without revealing the External Soul Bone. She also explains Ling Yu’s Spiritual Appraisal, prompting Dugu Bo to seek his help identifying the plants in his medicinal garden 48 49.

Ling Yu’s subsequent treatment of Dugu Bo and acceptance as his disciple bring him into the family as Dugu Yan’s junior brother. During their first family dinner, she notices her grandfather’s hair turning black again and tearfully thanks Ling Yu. After learning about immortal herbs, she asks Dugu Bo to reserve one for Ye Lingling in repayment for curing her 53 54 55.

Appearance

Dugu Yan has deep-purple hair and green eyes, with slightly upturned eye corners 39 40.

• Hairstyle: Wears her hair in a neat side ponytail during an academy encounter 40.
• Academy clothing: Appears in a pale cyan gauze dress with winding-branch embroidery, and later in a crimson dress with black trim 39 40.
• Travel clothing: Wears a practical outfit for the Sunset Forest expedition 43.
• Poison-related feature: Her fingernails have a green coloration that fades after purification 47.

Personality

Dugu Yan is outspoken, proud, and mischievous. She asks Ling Yu for friendship without hesitation and frequently teases him and Ye Lingling about their growing closeness. With Ling Yu, her banter includes mock threats of poison, demands for his cooking, and delight in making him call her “Senior Sister” 40 42 44 55.

Her loyalty overrides her interest in valuable opportunities. She refuses to covet Ye Lingling’s Soul Bone, solemnly swears to keep it secret, and later asks that her friend receive an immortal herb. She also defends Ling Yu when Dugu Bo dismissively calls him a brat 46 49 55.

Beneath her usual cheerfulness, she is deeply affected by her family’s poisoning. She hides her suffering from Ye Lingling, worries about treating her grandfather without breaking her oath, and cries with relief when she realizes his health is improving 47 55.

Abilities & Skills

Jade Phosphorous Serpent

Dugu Yan possesses the Dugu Family’s inherited Jade Phosphorous Serpent Martial Soul and uses poison in combat 31 45 53.

• Martial Soul Possession: Activates it while preparing to defend against the Soul Beasts surrounding the Glazed Deer 45.
• Jade Phosphor Purple Poison: Spreads it outside Ye Yilan’s bamboo grove to establish an additional defensive perimeter 45.
• Identified traits: Ling Yu’s Spiritual Appraisal detects corrosion and poisoning when examining her through their Ring Fusion connection 47.
• Remaining flaw: Even after her congenital poison is described as cured, Ling Yu states that her Martial Soul still has a flaw. He suggests dragon-type Soul Rings as a possible means of improving its bloodline; no such improvement is shown 53 54.

Cooperation with Ring Fusion

Dugu Yan can supply Soul Power to Ling Yu because his Ring Fusion talent adapts to outside energy; this compatibility is enabled by his talent rather than an independent transfer ability of hers 42.

• Successfully transfers Soul Power during his training experiment 42.
• Supplies energy he uses to assist Ye Lingling against the Glazed Deer’s influence 45.
• Recognizes its potential to sustain an attacking teammate during a Soul Master Tournament 42.

• Ye Yilan / Aunt Lan — Companion and senior protector during the Sunset Forest hunt. Dugu Yan reassures her that she will not take Ye Lingling’s Soul Bone and joins the oath protecting its secrecy 43 45 46.
