Background / History

Dugu Yan lost her parents when she was young. Her grandfather, Dugu Bo, remained deeply protective of her and later asked Xia Yuan to cherish her after learning of her confession 56.

Her family inherited the Jade Phosphorous Serpent Martial Soul, whose poison could corrode its user’s body. Dugu Bo sought a suitable Soul Bone to contain her toxins, but had not obtained one by the time Xia Yuan began treating her 22 28 39.

Appearance

Her documented physical changes occur during Martial Soul Possession, particularly after absorbing Dragon Jade Grass 62.

• Original possession: Her legs transformed into a snake tail 62.
• Evolved possession: Her legs remain separate, while a green dragon-like tail grows from her back 62.
• Eyes: Green vertical-slit pupils during possession 62.
• Horns: Two green dragon horns appear on her forehead and glow when she uses her evolved second soul skill 62 84.
• During herb absorption: Her skin temporarily takes on a jade coloration 62.

Personality

Dugu Yan is outspoken, teasing, and willing to act for people she cares about. After Xia Yuan’s conflict with Yu Tianheng, she privately arranged protection rather than leaving him exposed to possible retaliation. She also challenges Yu Tianheng’s dismissive attitude toward Xia Yuan 20 21 48.

Her affection can make her competitive and jealous. She initially denies liking Xia Yuan, later acknowledges her feelings, and becomes frustrated when other women develop Martial Soul Fusion Skills with him while she cannot 21 41 142.

Despite her aggressive poison techniques, she shows concern for others’ safety. She hesitates over Xia Yuan’s treatment wound and withholds poison near surviving villagers before using it against the Wolf Bandits away from them 40 144.

Abilities & Skills

Jade Phosphorous Poison Dragon

• Evolves from the Jade Phosphorous Serpent after she absorbs Dragon Jade Grass 62.
• Exerts enough bloodline pressure for Dugu Bo to feel suppression despite possessing the Jade Phosphorous Serpent Emperor 62.
• Strengthens her physical constitution while retaining poison as her primary means of attack 62.
• Has not reached the level of a True Dragon, but its foundation allows her to challenge top-tier Martial Souls such as the Blue Lightning Tyrant Dragon 62.

Poison Soul Skills

Soul Skill	Effect / Application
First skill — name unspecified	Enhances her poison offense; used before her fourth skill’s explosion 90.
Second skill — Myriad Transformations Poison Dragon	Sends out emerald, dragon-shaped poison projections carrying Jade Phosphorus Purple Poison. After evolution, ordinary flames cannot burn them away or neutralize them 84.
Third skill — Jade Phosphorus Purple Poison	Releases poisonous mist that she can subsequently withdraw 84.
Fourth skill — name unspecified	Produces a poison explosion, completing her four-skill offensive sequence 90.

• Overwhelming same-realm offense: Her full four-skill sequence is described as more than Soul Masters of the same rank can withstand 90.
• Anti-air pressure: She attacks Huo Yun and Huo Yu with poison dragons; Huo Yun is poisoned into falling before Xia Yuan restrains him 84.
• Area denial: Her dragon poison brings down numerous Wolf Bandits before they can reach the group 144.
• Defensive limitation: Her poison can be defended against to some extent, unlike poison forcibly injected through Tang San’s Eight Spider Lances 120.

Toxin Control and Treatment

• Can force accumulated Martial Soul poison out through her fingertip after taking Xia Yuan’s medicinal catalyst 40.
• Transfers those toxins into a wound on Xia Yuan’s arm. His resistance allows him to receive them safely, while the poison helps stimulate the medicinal power remaining inside him 39 40 44.
• Directly dissolving her toxins without a suitable vessel would also dissolve her poison arts, making indiscriminate detoxification unsuitable 39.
• Whether her dragon evolution completely resolves the underlying poison flaw is not confirmed during her immediate assessment 62.

Martial Soul Fusion Potential

• Has no demonstrated Martial Soul Fusion Skill with Xia Yuan, despite both Martial Souls possessing dragon-related qualities 141 142.
• Resolves to develop one after witnessing Huo Wu and Shui Bing’er’s successful fusions 142.
• Imagines the name “Jade Phosphorous Dragon Emperor” for a possible fusion; this remains speculation, not an acquired skill 142.

Equipment / Items

• Dragon Jade Grass — Immortal-grade herb gifted by Xia Yuan; consumed to evolve her Martial Soul and raise her Soul Power by four ranks 61 62.
• Medicinal catalyst — Xia Yuan’s preparation used to help guide accumulated toxins out of her body 40.
• Antidote pill — Supplied by Dugu Bo for passage through his poison formation; her cultivation alone does not protect her from it 61.

Relationships

• Dugu Bo — Grandfather and protective elder. Responds to her request to guard Xia Yuan, seeks a Soul Bone for her treatment, and watches over her Martial Soul evolution 21 28 62.
• Xia Yuan — Romantic interest, teammate, and cultivation guide. She protects him through her grandfather’s help; he treats her poison and supplies the herb responsible for her evolution. Her confession is confirmed by his conversation with Dugu Bo 21 39 56 62.
• Ye Lingling — Friend, teammate, and romantic rival. Dugu Yan initially confronts Xia Yuan over a rumor that he bullied her, then later competes with her for his affection 17 41.
• Yu Tianheng — Academy acquaintance whose claims initially mislead her. She avoids his attempted touch after recognizing the misunderstanding and later openly defends Xia Yuan against his arrogance 17 48.
• Huo Wu and Shui Bing’er — Their successful fusions with Xia Yuan intensify her jealousy and determination to establish her own compatibility with him 142.

Story Role / Major Arcs

Academy Conflict and Dugu Bo’s Intervention

Dugu Yan confronts Xia Yuan after Yu Tianheng claims he bullied Ye Lingling, but realizes she should have verified the story herself. Following Xia Yuan’s victory over Yu Tianheng, she asks Dugu Bo to protect him from possible retaliation. This request brings Xia Yuan into contact with the elder who later grants him access to the Ice and Fire Yin Yang Well 17 20 21 24.

Dugu Bo subsequently proposes marrying her to Xia Yuan. Xia Yuan declines at that time, citing his youth and lack of feelings for her; the proposal does not establish an engagement 27.

Treatment and Martial Soul Evolution

Dugu Yan begins cultivating alongside Xia Yuan and Ye Lingling while Xia Yuan removes her accumulated poison. Her growing affection becomes explicit, and Xia Yuan later tells Dugu Bo that she has confessed to him 39 40 41 56.

At the outskirts of the Ice and Fire Yin Yang Well, she absorbs Dragon Jade Grass under Xia Yuan and Dugu Bo’s supervision. The resulting evolution transforms her inherited serpent Martial Soul into a poison dragon 61 62.

Imperial Fighting Team Battles

Dugu Yan helps defeat Blazing Fire Academy’s trio with her evolved poison techniques and fights alongside the Imperial Fighting Team against the Fierce God Team. In the tournament final, she joins Xia Yuan’s clone against Yan and the remaining Spirit Hall teammates while Xia Yuan confronts Demon Charm 84 90 121.

Journey South

After Xia Yuan returns from Slaughter City, Dugu Yan and Ye Lingling travel south with him. At Four Elements City, her frustration over lacking a fusion skill grows after Huo Wu and Shui Bing’er successfully fuse with him 139 140 142.

She later uses her dragon poison against Wolf Bandits while avoiding harm to surviving villagers. The group continues to Dragonrise City and visits the Defense Clan 144.
