Background / History

Recruitment at the Ice and Fire Yin Yang Well

Dugu Bo spends his life studying poison, yet cannot cure the poisoning caused by his own Poison Technique. He uses the Ice and Fire Yin Yang Well to suppress its effects and keeps both his refuge and his illness secret—even from Dugu Yan 12 13 15.

When Dai Chengqian and Zhu Zhuqing enter the valley, Dugu Bo threatens them and demands to know how they discovered it. Dai instead identifies his private symptoms and offers a bargain: help resolve the poison backlash affecting both grandfather and granddaughter in exchange for Dugu Bo becoming his nominal retainer 12 13.

Dugu Bo initially dismisses the offer, then considers it after hearing a concrete treatment method. He tests Dai with a Titled Douluo’s mental pressure, prompting Bai Qingyue to intervene. Dai asks her to stand aside, withstands the pressure without retreating, and reveals a ten-thousand-year third soul ring. Impressed by his potential and composure, Dugu Bo accepts the agreement 13.

Relocation to Star Luo

After joining Dai, Dugu Bo permits him to select herbs freely from the valley, warning that some are poisonous. He rushes to examine Dai when the prince consumes the Octagonal Mysterious Ice Grass and Infernal Delicate Apricot, then waits nearby while Dai absorbs their properties in the well 14.

Before moving to Star Luo, Dugu Bo insists on collecting Dugu Yan from Heaven Dou Royal Academy. She initially refuses to transfer, but he explains his illness and the agreement with Dai. After losing a voluntary duel against Dai, she agrees to join his team; Dugu Bo helps complete her withdrawal paperwork 14 15 16.

Dai later settles him at the Imperial Prince’s Residence and secures the Star Luo Emperor’s agreement to provide medicinal experts and a Titled Douluo for his treatment. The emperor recognizes the military value of bringing Poison Douluo into Star Luo’s camp 20 21.

Black Rose Team Training

Dugu Bo and Bai Qingyue become the Black Rose Team’s sparring instructors. During the second training phase, the seven members must survive one incense stick against either Titled Douluo. The instructors restrain their strength but repeatedly defeat the entire team; Dugu Bo refuses to give his granddaughter special treatment 24 25.

As the qualifiers approach, he urges members who have reached level 40 to obtain their fourth soul rings. He accompanies the subsequent hunt and questions Dai’s plan to absorb a thirty-thousand-year ring. When powerful fighting erupts deeper in the forest, Dugu Bo evacuates all seven younger members and continues flying until they are dozens of kilometers clear of the danger 25 26 27.

Heaven Dou Tournament Visit

Dugu Bo transports Dai and his companions to Heaven Dou City to observe the tournament preliminaries, serving as their open protector while Bai Qingyue remains concealed. He jokes that becoming a retainer has turned him into Dai’s carriage 31.

Invited alongside Dai to the Heaven Dou Emperor’s VIP stand, he identifies prominent attendees, including Ning Fengzhi and a Spirit Hall Platinum Bishop, and comments on the attention Dai’s unusual soul rings could attract 32.

Appearance

• Elderly and bearded: He strokes his beard while considering Dai’s proposal; Dugu Yan also playfully threatens to tug it 13 14.
• Hoarse voice: His voice echoes through the valley before his first appearance 12.
• Intimidating gaze: His initial encounter with Dai features a cold, vicious gleam and visible killing intent 12.
• Green-mist entrance: He arrives inside a cloud of green mist, which disperses to reveal him standing with his hands clasped behind his back 12.

Personality

Dugu Bo presents a ruthless, suspicious exterior. He threatens intruders, mocks unsupported promises, and demands evidence before accepting Dai’s claims. His skepticism is practical: he immediately recognizes that carelessly forcing poison out with soul power could worsen its backlash 12 13.

His concern for Dugu Yan is his strongest motivation. Although he does not fear his own death, he refuses to leave his only granddaughter to the same poisoning. He conceals his suffering to spare her worry and openly dotes on her during their reunion 13 14 15.

Dai finds that beneath his severe manner, Dugu Bo values affection and keeps his word. Once the agreement is settled, he follows Dai to Star Luo and takes on protection and training duties. Their relationship becomes informal enough for teasing, and Dugu Bo openly enjoys Dai’s flattery 14 19 31.

His affection does not make him indulgent as an instructor. He rejects Dugu Yan’s request for easier treatment because tournament opponents will not spare her. He also respects Dai’s privacy, declining to press him about the origin of his fifty-thousand-year fourth soul ring 25 29.

Abilities & Skills

Poison Expertise

Dugu Bo is a lifelong poison researcher whose expertise makes him especially valuable against large groups 12 13 21.

• Continues experimenting with poisons during travel, unpacking bottles and jars when the party pauses 18.
• Uses green mist from the Jade Phosphorous Serpent as a defensive screen; it absorbs the Soul Light Ray’s beams with only a small patch being eroded 26.
• Is assessed by Dai as relatively unexceptional among Titled Douluos in single combat, but potentially decisive on a large battlefield 12 21.
• Cannot independently resolve the poison backlash in his own body despite his expertise 13.

Titled Douluo Pressure

Dugu Bo can direct a powerful mental assault at an opponent while manifesting his nine soul rings 13.

• Uses this pressure to test Dai’s courage and cultivation potential 13.
• Recognizes Bai Qingyue as a dangerous opponent and judges that he would likely lose a direct confrontation with her 13.

Aerial Transport and Evacuation

Dugu Bo can carry multiple passengers through the air using green mist or his manifested serpent 14 27.

• Wraps Dai and Zhu Zhuqing in mist for rapid travel to Heaven Dou City 14.
• Enlarges the Jade Phosphorous Serpent and uses its tail to carry Dai and all six teammates out of the Star Dou Great Forest 27.
• Senses two exceptionally powerful forces fighting in the forest and tentatively identifies one as the Titan Giant Ape 27.

Combat Instruction

Dugu Bo trains the Black Rose Team through repeated, controlled battles against Titled Douluo-level opposition 25.

• Restrains his power without making the encounters easy 25.
• Gives Dugu Yan no exemption from the training’s demands 25.
• Helps the team obtain suitable fourth soul rings before the qualifiers 26.

Poison Backlash and Treatment

Aspect	Details
Cause	His Poison Technique causes poison to accumulate in his body; his beast martial soul allows the poison to fuse with his flesh 13.
Rain-related symptoms	Numbness and itching around the ribs during overcast, rainy weather, with episodes described by Dai as lasting over two hours 12.
Nighttime symptoms	Stabbing pain begins at the crown of his head and soles of his feet before spreading throughout his body 12.
Existing suppression	The Ice and Fire Yin Yang Well suppresses the poison but cannot eliminate it; continued accumulation may eventually prove fatal 13.
Dugu Yan’s risk	Practicing the same technique has poisoned her as well. She lacks her grandfather’s Titled Douluo strength to contain it and refuses his request to stop practicing 13.
Proposed treatment	Use a specific medicinal prescription to gradually channel the poison into a soul bone, potentially with another Titled Douluo’s assistance 13.
Treatment limitation	Forcing the poison out directly with soul power could accelerate the backlash 13.
Imperial assistance	Dai requests pharmacists and a Titled Douluo, suggesting assistance approximately once a month; the emperor agrees 21.

Equipment / Items

• Storage Soul Tool — Holds the bottles and jars used in his poison research 18.
• Soul Light Ray — Receives one from Dai as thanks for training and protection; judges its attack power comparable to an ordinary Soul Master in their thirties 26.
• Soul Power Milk Bottle — Included in his gifted soul-tool set; replenishes stored soul power 25 26.
• Soul Tool Thrusters — Speed-enhancing tools included in the same set 26.
• Soul Tool Bracelet — Storage equipment included in the same set 26.

Relationships

• Dugu Yan — His only granddaughter and principal reason for accepting Dai’s bargain. He is affectionate toward her but uncompromising during combat training 13 14 25.
• Dai Chengqian — Patron and prospective benefactor. Their cure-for-service agreement develops into practical cooperation and friendly teasing 13 19 31.
• Bai Qingyue — Fellow protector and training instructor. She initially confronts him during Dai’s test; they later cooperate in sparring and soul-beast hunts 13 25 26.
• Star Luo Emperor — Approves resources for his treatment after hearing Dai’s assessment of his wartime value 21.
• Black Rose Team — Protects, transports, and trains the seven-member tournament team 25 27 31.
• Dragon Duke and Snake Granny — Their surprise at his close association with Dai highlights the unusual influence of a prince supported by two Titled Douluos 18 19.
