Power Progression

Stage / Realm / Level	Chapter	Notes
Martial Soul mutation begins	139	Refining Dragon Transformation Grass loosens her Soul Power bottleneck and begins changing her serpent Martial Soul. Its uncontrolled energy nearly kills her, requiring Xiao Chen’s intervention.
Peak Level 39; Jade Scale Flood Dragon	140	Dragon Transformation Grass, Martial Soul Consolidation Fluid, and Xiao Chen’s blood complete the evolution. Her physical strength becomes comparable to some four-ring Assault System Soul Ancestors.
Level 40, awaiting a Fourth Soul Ring	214	Confirmed to have reached Level 40 with Xiao Chen’s help. Dugu Bo delays her next ring to discourage arrogance and give her time to develop a relationship with Xiao Chen.
Four-ring Soul Ancestor	257	Successfully absorbs a ten-thousand-year Fourth Soul Ring supplied by Xiao Chen, with his assistance. The resulting Soul Power level and Fourth Soul Skill are not specified.

• Long-term potential: Xiao Chen seals much of the Dragon Transformation Grass’s energy inside her first three Soul Rings, prioritizing her physical foundation and Martial Soul development over immediate levels. He regards a future Level 90 Titled Douluo breakthrough as practically guaranteed—not an achievement she has already reached 140.

History

Imperial Dou Team and the treatment agreement

Dugu Yan encounters Xiao Chen during the Imperial Dou Team’s battle against his Nameless Team at the Suo Tuo Great Spirit Arena. She asks whether he can treat the poison associated with her Jade Scale Snake Martial Soul, placing particular importance on helping her grandfather, Dugu Bo. Xiao Chen considers her condition relatively straightforward because she is young, but insists on compensation and a personal examination of Dugu Bo 130.

She initially tries to negotiate through flirtation and her standing as a Titled Douluo’s granddaughter. Xiao Chen counters with physical intimidation and warnings about her poison’s potentially fatal consequences. She accepts six months of treatment and residence with him, while stipulating that he must not touch her without permission 131.

After formally conceding the team battle, she arranges care for her injured teammates and describes her departure as a six-month business negotiation. Yu Tianheng objects, but Dugu Yan makes clear that she has never formally accepted him as her partner. She subsequently moves into Shrek Academy’s girls’ dormitory with Flender’s approval 132 135.

Martial Soul evolution and poison treatment

Xiao Chen finds that her poison has mixed with her blood and Soul Power, though the fusion is not yet severe. His treatment uses Dragon Transformation Grass, whose energy overwhelms her after she swallows part of it. He suppresses the dangerous surge through Soul Power transfer, taking her first kiss during the intervention 138 139.

The process evolves her Martial Soul into the Jade Scale Flood Dragon. Rather than letting the herb produce an immediate large breakthrough, Xiao Chen redirects its energy into her constitution and Martial Soul, sealing the remainder inside her Soul Rings 140.

Dugu Bo later arrives to investigate the proposed cure. Dugu Yan explains Xiao Chen’s claimed clan background and powerful protectors, but her grandfather knocks her unconscious to keep her out of the negotiations. Xiao Chen subsequently conducts a second treatment stage at the Ice and Fire Yin Yang Well, releasing more of the sealed medicinal energy 157 160.

The treatment is described as successful when Dugu Yan reunites with Dugu Bo and demonstrates her evolved Martial Soul. Her grandfather’s gratitude strengthens his alliance with Xiao Chen, although follow-up treatment remains part of their later arrangements 163 174.

Heaven Dou City and romantic attachment

Dugu Yan volunteers to guide Xiao Chen through Heaven Dou City and arrange contact with Liu Erlong. During their hotel stay, she unknowingly drinks Dream Wine mixed with Past Love Nectar, mistaking its effects for ordinary strong alcohol. Ning Rongrong records her resulting behavior with a Memory Stone and embarrasses her with it the next morning 174 175 176 177.

Afterward, Dugu Yan resolves not to become intimate with Xiao Chen again unless he openly expresses his feelings and proves his sincerity. Their relationship later takes the form of a one-day girlfriend arrangement. His attentive behavior during their shopping date makes her consider turning it into a lasting relationship 177 214 215.

When Taino confronts Xiao Chen, Dugu Yan intervenes using Dugu Bo’s reputation. She is subsequently injured by attacks spilling out of the duel, and Xiao Chen shields her from a third strike. After he defeats Taino, she openly confesses that she likes him and asks to spend time somewhere private 216 217 218.

Companions, advancement, and tournament combat

Dugu Yan becomes more integrated into Xiao Chen’s circle, reconciling with the other women while continuing to compete for his attention. She encourages Bai Chenxiang to become stronger and pursue him, then prevents Bai He from interrupting Bai Chenxiang’s Martial Soul treatment 231 232 235.

Her concern for Dugu Bo remains strong. When Yue Guan challenges him, she accompanies Xiao Chen to the battlefield, worries over her grandfather’s injuries, and reprimands him afterward for fighting recklessly 242 243 244.

Xiao Chen eventually supplies her with a ten-thousand-year Fourth Soul Ring. After absorbing it, she joins the other women in special training and later fights alongside Bai Chenxiang in the tournament, using her Flood Dragon Claws to intercept and eliminate an opponent transformed into a Diamond Cannonball 257 298 331.

Appearance

Dugu Yan has emerald-green eyes, fair skin, and a slender, flexible waist repeatedly compared to a snake’s 131 214 220.

• Cool skin: Its unusually low temperature is attributed to her Martial Soul 138.
• Jade-green attire: Xiao Chen gives her revealing, gauze-like battle clothing embroidered with flood dragons 137.
• Martial Soul transformation: Her evolved Martial Soul is jade green and emits faint Dragon Might; in combat, her hands can become jade-green Flood Dragon Claws 140 331.

Personality

Dugu Yan is proud, competitive, and accustomed to attracting admirers. She initially assumes that her charm and family status will give her leverage over Xiao Chen, and she dislikes being compared unfavorably with his other companions. Even during painful treatment, she tries to preserve her dignity and interpret small concessions as victories 131 137 138 162.

Her loyalty to Dugu Bo repeatedly outweighs her pride. She accepts an uncomfortable treatment arrangement partly to secure help for him, mediates his first meeting with Xiao Chen, and reacts strongly when his safety is threatened 130 135 157 243.

Her growing affection for Xiao Chen develops alongside dependence, jealousy, and supernatural manipulation. She eventually becomes openly affectionate and playful with him, but also seeks reassurance of his sincerity. Her rivalry with Ning Rongrong does not prevent her from supporting Bai Chenxiang as a friend and prospective ally 177 215 219 233 257.

Abilities & Skills

Jade Scale Snake and inherited poison

• Her original Martial Soul carries poison that also harms its wielder, becoming mixed with her blood and Soul Power 138.
• Xiao Chen warns that the condition can eventually kill her and endanger people who remain close to her 131.
• The Ice and Fire Yin Yang Well can delay the poison’s onset, but cannot permanently save her on its own 159.
• Her first three Soul Rings are not assault-oriented, leaving them poorly matched to her later Assault System evolution 217.

Jade Scale Flood Dragon

• Retains potent venom while adding faint Dragon Might and substantially greater physical strength 140.
• Gives her an Assault System Martial Soul and a stronger constitution than her original serpent form 217 220.
• Can transform her hands into Flood Dragon Claws. A thousand-year Soul Ring empowers her clash with a Diamond Cannonball opponent 331.
• Allows her to withstand two attacks from a five-ring Soul King, but the second leaves her unable to maintain her Martial Soul 217.
• Powerful attacks can still require recovery time: after eliminating the Diamond Cannonball opponent, she tells Bai Chenxiang that she needs time to recover 331.

Enhanced perception

• Her evolved Martial Soul improves her perception, helping her monitor Bai Chenxiang’s transformation 235.
• She senses the presence of a hundred-thousand-year soul beast near Ah Yin’s residence, initially uncertain whether it is an ally 298.

Equipment & Treatment Items

• Jade-green battle attire — Supplied by Xiao Chen for treatment. He claims it can withstand five-ring Soul King attacks; Dugu Yan confirms that her own Soul Power cannot tear it 137 138.
• Protective jade pendant — Nears its breaking point as Taino’s third attack approaches during the duel 217.
• Dragon Transformation Grass — Drives her Martial Soul evolution and improves her foundation, but requires Xiao Chen to suppress and regulate its overwhelming energy 139 140.
• Martial Soul Consolidation Fluid — Used during the evolution process alongside Xiao Chen’s blood and medicinal energy 140.
• Dragon Spirit Tiger Gall Tea — Given to her during treatment preparations. Its stated effects on women include heightened sensitivity and feverishness 136 137.
• Ten-thousand-year Fourth Soul Ring — Supplied directly by Xiao Chen rather than obtained through a conventional hunt 256 257.

Relationships

• Dugu Bo — Grandfather and protector. Their close bond motivates her search for treatment and his willingness to make major sacrifices for her survival. He later encourages her relationship with Xiao Chen 130 156 157 159.
• Xiao Chen — Healer, cultivation benefactor, and eventual romantic partner. His assistance cures her poison and evolves her Martial Soul, but he also uses dependency, intimidation, and emotion-altering items to influence her 139 140 163 176 218.
• Yu Tianheng — Imperial Dou Team captain and would-be partner. She rejects his possessive objections to her departure, stating that she has never formally agreed to become his partner; she nevertheless fears for his life when Xiao Chen retaliates against his sneak attack 134 135.
• Ning Rongrong — Romantic rival. Their early hostility includes arguments over family power and a Memory Stone recording used to embarrass Dugu Yan. They later reconcile, although competition for Xiao Chen’s favor continues 135 177 231 232.
• Ye Lingling — Former teammate and fellow companion of Xiao Chen. Dugu Yan is unsettled by her willingness to cooperate with him and envies her cultivation rewards; both later receive ten-thousand-year Fourth Soul Rings 144 146 213 257.
• Bai Chenxiang — Close friend and younger-sister figure, not a confirmed biological sibling. Dugu Yan supports her pursuit of Xiao Chen, protects her treatment from interruption, and fights alongside her in the tournament 232 233 235 242 331.
• Princess Xue Ke — Familiar friend who greets her affectionately as “Sister Yan’er.” Xue Ke notices that Dugu Yan praises Xiao Chen without mentioning his flaws 316.
