Background / History
Dugu Yan is Poison Douluo Dugu Bo’s granddaughter and inherits the Jade Phosphorous Serpent martial soul. Like her grandfather, she suffers from the toxins produced by its cultivation. Having witnessed his painful attacks, she seeks a treatment that could help them both 18 19.
As vice-captain of the Imperial Fighting Team, she participates in the Crown Prince’s arranged match against Murong Ci’s team. Her poisonous mist envelops the arena, but Murong Ci destroys it with Ultimate Ice, leaving her heavily injured. He then defeats the entire Imperial Fighting Team with Hundred Years in an Instant 18.
Afterward, Dugu Yan follows Murong Ci into a secluded alley and asks whether his ice can alleviate their poisoning. He agrees to suppress her toxins, explaining that her grandfather’s greater strength prevents him from offering a complete cure at his current level. She arranges to meet him at Heaven Dou Royal Academy three days later and introduces him to Dugu Bo 19 20.
Dugu Bo takes them to the Ice and Fire Yin Yang Well, where Murong Ci successfully performs her first detoxification. Although her grandfather initially orders daily treatment for a month, her condition improves much sooner: after absorbing the Snow Silkworm and receiving a second treatment, only a small amount of residual poison remains. Murong Ci sends her home to rest, expecting her to recover within days 21 22 23 24.
During Murong Ci’s subsequent month of cultivation at the well, she returns for brief poison-clearing sessions. Their meetings become noticeably reserved, a change that leaves him puzzled 26.
Appearance
Dugu Yan is described as a beautiful, full-chested young woman. During her departure from the well, she wears a dress or skirt with small white shoes 19 24.
- Her face becomes deathly pale when Murong Ci destroys her poisonous mist 18.
- Her cheeks flush during treatment and when Dugu Bo identifies Murong Ci as the strong young man she had mentioned 20 21.
Personality
Dugu Yan initially presents a cool, competitive demeanor. Before the arranged match, she rebukes Yu Feng for undermining the team’s morale and insists that they concentrate on fighting rather than fearing Murong Ci’s reputation 18.
Her concern for Dugu Bo reveals a more vulnerable side: she nearly cries while describing his suffering and asks for help despite her recent defeat. She is also persistent in cultivation, continuing to absorb the Snow Silkworm while sweating and trembling, and later directly requests stronger treatment once her cold resistance improves 19 22 23.
She develops an attraction to Murong Ci, but becomes subdued when he tells her to return home after treatment. Her later visits remain short and emotionally distant rather than establishing a confirmed romantic relationship 20 24 26.
Abilities & Skills
Jade Phosphorous Serpent
Her inherited martial soul specializes in highly toxic attacks 18.
- Toxic cultivation drawback: Its poison harms the user’s own body. Flare-ups are associated with rainy weather, paralysis, and joint pain 19.
- Poison delivery: She uses a poisoned needle during her encounter with Murong Ci; traces of its poison remain on him afterward 19.
Third Soul Skill: Jade Phosphorous Purple Poison
The Jade Phosphorous Serpent releases purple poisonous mist capable of covering an entire arena 18.
- Team-battle coverage: The fog catches Huo Wu, Huo Wushuang, and Feng Xiaotian while they are attacking the Shi Brothers, then spreads to Murong Ci 18.
- Elemental counter: Murong Ci’s Ultimate Ice destroys the toxins. The counter leaves Dugu Yan heavily injured 18.
Relationships
- Dugu Bo — Grandfather and source of her inherited martial soul. She seeks relief for his poisoning as well as her own; he prioritizes her treatment and later considers Murong Ci a prospective grandson-in-law 18 19 21 24 25.
- Murong Ci — Initially an opponent, then her detoxification provider and cultivation helper. She becomes attracted to him, though their later encounters grow reserved 18 19 20 22 24 26.
- Yu Tianheng — Captain of the Imperial Fighting Team. She supports his attack with poisonous mist, and he expresses strong confidence in her effectiveness in team battles 18.
- Qin Ming — Her team’s teacher. She tells Dugu Bo that Qin Ming has recruited the Shrek team to join Heaven Dou Royal Academy 19.
