Background / History

Dugu Bo raised his granddaughter, Dugu Yan, for over a decade and is her only remaining relative. He considers her and the Immortal-Grade Herbs at the Ice and Fire Yin Yang Well his two greatest treasures. He tended the herbs for decades, sealing the valley in Sunset Forest behind a Poison Barrier to prevent outsiders from approaching 6 7 9 58 59.

Despite his mastery of poison, Dugu Bo suffered for decades from the backlash of his own Jade Phosphorous Serpent Poison, which had penetrated his bones. His knowledge of the garden’s herbs was incomplete: he warned Dugu Yan that they were deadly but did not understand how to use them to treat their family’s condition 7 9.

Prince Xue Xing previously saved Dugu Bo from Yue Guan, leaving him with a life debt. Dugu Bo later serves the Heaven Dou Empire as a Guest Official. After being sent to investigate false information about the stolen Vast Sea Cosmic Shroud, he resolves to finish repaying Xue Xing and sever his imperial ties; his resignation is not shown in the provided chapters 68.

Appearance

• White hair and aged features: Yue Guan’s attacks cut several strands of his white hair; his hands are described as rough and aged 9 68.
• Serpent Emperor Avatar: Transforms into a giant serpent dozens of meters long, with jade-green scales, a scarlet tongue, and dark-green metallic-looking armor. Poison mist continuously escapes between its scales 68.

Personality

Dugu Bo has a reputation for being unpredictable and acting according to his own wishes. His anger over the stolen herbs leads him to threaten the academy’s leaders with poison, while his granddaughter’s recovery quickly persuades him to reconsider Lin Ye’s actions. His fierce attachment to Dugu Yan also makes him controlling: he prevents her from following Lin Ye into the wilderness and initially objects to her marrying a man already married to Shui Bing’er 8 9 29 58.

Proud but realistic about his limitations, Dugu Bo seeks escape rather than a futile killing blow when Medusa’s Gaze briefly immobilizes Yue Guan. He keeps his word about approving Dugu Yan’s marriage and eventually admits that Lin Ye saved his life. Their relationship retains a competitive, teasing edge, particularly when Lin Ye calls him “Old Poison” or outpaces his flight 59 69 73.

Abilities & Skills

Jade Phosphorous Serpent Emperor Poison

• Corrosive attacks: Releases poison as mist, concentrated streams, or beams. It can melt chrysanthemum petals and blacken the ground 68 69.
• Wide-area combat: His fighting style favors broad poison coverage rather than close-range exchanges 71.
• Poison defense: Coils the Serpent Emperor phantom around himself and forms barriers of poison mist 68.
• Self-poisoning: His own poison originally caused prolonged backlash. Lin Ye’s treatment removes this burden and improves the poison’s purity 9 68.
• Limitations: Stronger attacks can penetrate his poison defenses, while fast opponents such as Gui Mei can prevent him from establishing distance 68 71.

Medusa’s Gaze

• Source: A skill granted by his Head Soul Bone 61 69.
• Effect: Petrifies a target, briefly interrupting movement and creating an opening to attack or escape 61 69.
• Against the Titan Snow Demon: The beast quickly shatters the petrification, but the brief restraint allows Lin Ye to strike 61.
• Against Yue Guan: Holds him for less than two seconds—too briefly for Dugu Bo to kill him with his available offensive techniques 69.

Sixth Soul Skill — Jade Phosphorous Serpent Emperor Break

• Condenses emerald poison mist into an enormous Serpent Emperor phantom and drives it into the target 62.
• Primarily a control-type skill. Against the hundred-thousand-year Titan Snow Demon, it briefly restricts movement but causes little direct damage 62.

Seventh Soul Skill — Martial Soul Avatar

• Transforms Dugu Bo into the Jade Phosphorous Serpent Emperor, strengthening his poison attacks and physical defenses 63 68 69.
• His armored scales withstand Yue Guan’s Golden Stamen Streaming Rosy Clouds without being pierced, although the impacts still cause pain 69.
• The enlarged body makes him an easier target for skilled opponents 69.

Snow-White Swan Kiss–Amplified Poison

• Uses an extract supplied by Lin Ye to magnify poison toxicity a thousandfold 62 63.
• During the Titan Snow Demon hunt, injects the amplified poison into an exposed wound, where it begins consuming the beast’s icy power 63.
• Later uses two reserved drops to produce poison powerful enough to reduce stone to powder and force Gui Mei to retreat 70.
• Danger to the user: Dugu Bo recognizes that the amplified poison could kill him as well 62 70.
• Countermeasure: Yue Guan and Gui Mei’s Two Extremes Stillness Domain freezes both Dugu Bo and the poison in place 70.

Flight

• Can fly as a Titled Douluo and carry Dugu Yan through the air 59.
• His flight speed is inferior to Lin Ye’s External Soul Bone wings 59.

Equipment / Items

• Head Soul Bone — Grants Medusa’s Gaze. Dugu Bo obtained it through luck after decades of traveling; Yue Guan and Gui Mei seek to kill him partly to seize it 59 69.
• Storage Soul Tool — Holds the medicine bottle containing his reserved Snow-White Swan Kiss extract 70.
• Snow-White Swan Kiss extract — Lin Ye supplies it for the Titan Snow Demon hunt. Dugu Bo secretly keeps two drops for an emergency 62 70.
• Poison Barrier passage pills — Dugu Yan obtains pills that allow Lin Ye to cross the barrier around the Ice and Fire Yin Yang Well 6 7.
• Immortal-Grade Herb garden — A treasured collection cultivated for decades. Dugu Bo relinquishes his claim to the harvested herbs in exchange for treatment and assistance with Dugu Yan’s advancement 7 9.

Relationships

• Dugu Yan — Granddaughter and only remaining family member. He is deeply protective of her, restricts her travel, and eventually approves her marriage to Lin Ye after Lin Ye fulfills his cultivation promise 29 58 59.
• Lin Ye — Initially the thief of his treasured herbs; later his healer, prospective grandson-in-law, and combat partner. Dugu Bo helps obtain his Eighth Soul Ring, conceals his theft of the Vast Sea Cosmic Shroud, and acknowledges owing him his life 9 59 64 65 73.
• Prince Xue Xing — Former rescuer and source of Dugu Bo’s obligation to the Heaven Dou Empire. Dugu Bo accepts his request to investigate the stolen Shroud but secretly protects Lin Ye 65 68.
• Yue Guan — Enemy who previously attempted to kill him and later engineers another ambush. Yue Guan covets Dugu Bo’s Head Soul Bone 68 69.
• Gui Mei — Yue Guan’s concealed partner in the ambush. Blocks Dugu Bo’s escape, drains his Soul Power with Ghost Gate, and pressures him through superior close-range speed 69 71 72.
