Innate Level Nine Soul Power	33	Retrospectively identified as a once-in-a-generation prodigy who began traveling to resolve his family’s poison backlash.
Level 91 Titled Douluo; Jade Phosphor Serpent Emperor	21 60	His Martial Soul had evolved from the Jade Phosphor Serpent, enabling him to reach Titled Douluo. Its venom also strengthened, leaving further conventional advancement dangerously restricted.
Fifty-percent Steve Physique	12 13	Receives shared physical strength and MC World authorities from Gu Changge. These benefits function within Gu Changge’s world, not on Douluo Continent.
Experience-driven Soul Power growth	20 21	Monster kills increase pure Soul Power without increasing his Martial Soul’s poison, progressively diluting the backlash.
Level 99 Limit Douluo	23 24	Reaches Level 99 after grinding overnight, with the final breakthrough from Level 98 occurring shortly before the others arrive. Initially struggles to control his increased Soul Power.
Resonating Poison Pill and self-created Domain	24 25	A dangerous Soul Core experiment links his Poison Pill, Soul Power circulation, and Martial Soul.

Poison Dragon Martial Soul; second Dragon Pearl	79	Reveals an emerald-green Poison Dragon and a second pearl that Gu Changge attributes to the Star Luo Spirit Pearl. The new pearl and original Poison Pill become icy blue and scarlet as another transformation begins.

Background / History

Dugu Bo began his cultivation with Innate Level Nine Soul Power. Determined to overcome the Jade Phosphor Serpent lineage’s poison backlash, he joined Yue Guan, whose own goal was to find immortal-grade treasures. They traveled together for decades without finding a suitable immortal treasure 33.

Their friendship broke down when Dugu Yan’s father suffered worsening poison backlash after reaching the five-ring Soul King stage. Dugu Bo taught him an unfinished Poison Pill Condensation Method, but the failed attempt accelerated the poisoning. Desperate, Dugu Bo asked Yue Guan for his immature Jade Dragon Snow Ginseng. Yue Guan refused because the herb was incompatible and could only temporarily prolong life; Dugu Bo subsequently stole it from his medicine garden 33.

The ginseng extended Dugu Yan’s father’s life by less than a year rather than curing him. It gave her parents time to have her, but her mother also died from poison backlash during pregnancy. Dugu Bo and Yue Guan fought repeatedly afterward, with Gui Mei and Ye Lingling’s grandfather preventing their feud from escalating further 33 34.

Dugu Bo also shared a life-and-death friendship with Ye Guanlan’s father, who entrusted the newly married Ye Guanlan and Mu Qingyu to his care before dying. Separately, Gu Changge’s parents arranged for Dugu Bo to look after their son. After their deaths, he raised Gu Changge as his own grandson 1 6.

Appearance

• Initially has an aged face; drinking MC milk clears his existing poisoning and visibly rejuvenates him 3 20.
• His evolved Martial Soul appears as an emerald-green Poison Dragon 79.
• His earlier incomplete Flood Dragon transformation produces protrusions where horns and claws could develop 25.
• When preparing his later pearl technique, two pearls circle above him in icy-blue and scarlet forms 79.

Personality

Dugu Bo is fiercely protective of his family. His opposition to Gu Changge pursuing both Dugu Yan and Ye Lingling includes expelling him from the household and closely monitoring his granddaughter. Beneath that confrontation, however, he is testing whether Gu Changge can remain unyielding under pressure: believing his own poisoning could soon kill him, he wants to ensure Dugu Yan will have dependable protection 1 2 3.

He is stubborn and prideful, particularly toward Yue Guan. Mu Qingyu explains that both men eventually understood their old dispute, but neither would concede first. Nevertheless, Dugu Bo can acknowledge wrongdoing: after accepting Gu Changge’s relationships, he insists on personally apologizing to the Ye family 4 6 33.

His pursuit of a cure makes him inventive but reckless. He repeatedly improvises during his Poison Pill experiment despite the risk of destroying his Martial Soul, and later considers consuming three immature immortal treasures rather than enduring another day of backlash 25 60.

His newfound strength brings out a competitive, boastful streak. He enjoys humiliating old rivals, displays his breakthroughs proudly, and abandons fishing immediately when he learns that Yue Guan and Gui Mei are approaching his level 24 31 34 66.

Abilities & Skills

Poison Cultivation

Dugu Bo specializes in Jade Phosphor Serpent Venom and developed a Poison Pill Condensation Method to manage it 21 33.

• His poison affliction is intertwined with Soul Power, not merely a toxin in his physical body 21.
• Conventional cultivation can worsen the backlash; monster-derived experience instead adds poison-free Soul Power 21.
• Yue Guan later explains that the underlying problem is venom exceeding the Martial Soul’s capacity to contain it, rather than simply an innate defect 60.
• His immature condensation method is dangerous: teaching it to Dugu Yan’s father resulted in failure and accelerated poisoning 33.

Poison Pill Resonance

While attempting to create a Soul Core, Dugu Bo instead forms a unified resonating system between his Poison Pill, Martial Soul, and Soul Power circulation 25.

• The transformed pill absorbs and refines Soul Power and Soul Poison 25.
• It grows from thumb-sized to approximately the size of a child’s fist 25.
• It becomes semi-material and semi-illusory, residing inside his Martial Soul’s abdomen 25.
• Although it resembles a dragon pearl, it is explicitly not a true Soul Core 25.

Domains and Martial Soul Evolution

Dugu Bo independently condenses the Jade Phosphor Serpent Emperor Domain, whose purity and power impress Gu Changge 24.

• His initial evolution toward a Flood Dragon cannot complete because his lifelong emphasis on poison has left the Martial Soul’s Dragon Raja bloodline too weak 25.
• By his later confrontation with the Titan Giant Ape, his Martial Soul is a Poison Dragon and his Domain is described as the Poison Dragon Domain 79.
• His original Poison Pill and newer Dragon Pearl interact with the Domain to initiate a further transformation; its completed effects are not yet shown 79.

Shared MC World Authorities

Gu Changge grants Dugu Bo fifty percent of Steve Physique alongside shared authorities such as enhanced recovery and stamina 12 13.

• Serious injuries can heal rapidly when his Hunger Bar is replenished, provided he is not killed instantly 12.
• These shared powers remain subject to MC World rules and can be withdrawn by Gu Changge 1 13 35.
• He does not receive Gu Changge’s exclusive Immortal Body authority or infinite resurrection 12.
• He uses cooked meat to recover after nearly being killed by a Titan Giant Ape 77.

Combat

At Level 99, Dugu Bo can concentrate immense Soul Power into ordinary punches without activating a Soul Skill 31.

• Overwhelms Yue Guan with an unadorned punch 31.
• Brutally batters a fifty-thousand-year Darkgold Terrorclaw Bear before Gu Changge delivers the finishing blow 29.
• Possesses powerful eighth and ninth Soul Skills and a Medusa Petrifying Skull, which previously allowed him to resist the higher-level Yue Guan in single combat 33.
• His Douluo Continent Spirit Rings and Soul Bones remain inferior to the new Soul Master Continent’s power standard. A ten-thousand-year Titan Giant Ape nearly kills him with one punch despite his Level 99 cultivation 77.

Construction and Resource Development

• Builds a seven-layer Monster Grinding Tower after competing with Mu Qingyu and Ye Guanlan for stone 22.
• Adapts MC farming methods to immortal herbs, creating a glass enclosure with torches and bone meal; the medicine field matures overnight 64.
• Helps gather iron for the group’s equipment before their first expedition into Soul Master Continent 76.

Equipment / Weapons / Items

• Medusa Petrifying Skull — A top-grade Soul Bone contributing to his combat strength against Yue Guan 33.
• Poison Pill — His personally condensed poison-management vessel, later transformed into a dragon-pearl-like object 21 25.
• Second Dragon Pearl — Apparently formed through the Star Luo Spirit Pearl; used alongside his original Poison Pill 79.
• Stone Sword — Used to kill weakened monsters and accumulate experience at the Monster Grinding Tower 20 21.
• MC bed — Provides restorative effects and threefold cultivation speed; he brings one back to Douluo Continent 18.
• Triple Enchanted Fishing Rod — A rare catch he claims to have obtained in one cast; throws it at Gu Changge after learning Level 99 is not the limit 66.
• Iron Gear — Equipped for portal exploration; almost destroyed by the Titan Giant Ape’s attack 76 77.
• Medicine garden at the Ice and Fire Yin Yang Well — Contains immortal herbs sought for his Martial Soul’s improvement; Gu Changge later relocates the well into MC World 57 61.

Relationships

• Gu Changge — Raised him as a grandson and recognizes him as a prospective grandson-in-law. Their affectionate but combative relationship develops into cooperation as Gu Changge helps relieve his poisoning and unlock unprecedented cultivation opportunities 1 3 21 57.
• Dugu Yan — His granddaughter and foremost concern. He delights in her Martial Soul evolution, while she angrily confronts him over the danger of his cultivation experiments 24 27.
• Yue Guan / Chrysanthemum Douluo — Former traveling companion turned stubborn rival after the Jade Dragon Snow Ginseng dispute. Their insults and fights coexist with enduring attachment; Yue Guan later advises him on immortal herbs and supports his search for relief 33 59 60 61.
• Gui Mei / Ghost Douluo — An old acquaintance who helped mediate the feud with Yue Guan. Dugu Bo later forcibly brings both men into MC World as laborers 32 33 34.
• Ye Guanlan and Mu Qingyu — Juniors entrusted to his care by Ye Guanlan’s father. They address him as “Uncle,” and he personally apologizes for the trouble surrounding Gu Changge’s relationships 6.
• Ye Lingling’s grandfather — His life-and-death friend, who attempted to save Dugu Yan’s parents and helped restrain the feud with Yue Guan 6 33.
• Qian Renxue — Fellow participant in Gu Changge’s MC World; the two briefly fish together 64.
• Tang San and Tang Hao — Targets of his anger after Gu Changge describes an original destiny in which Tang San exploits him and the Dugu lineage disappears. Gu Changge prevents him from immediately seeking them out 57 58.
