Appearance

  • Build: Exceptionally burly and muscular, with a towering frame later compared to a giant bear 18 19 294.
  • Complexion: Rosy as a baby’s despite his advanced age 18.
  • Hair and eyes: Long, dark-green hair and large, bell-like eyes 19.
  • Presence: Projects oppressive pressure even through an image projection; his voice repeatedly booms like thunder 18 19.
  • Combat transformations: Can become a hundred-meter giant surrounded by poisonous haze. During the succession duel, his combined awakening and Martial Soul Avatar expand him to a thousand feet 109 294.

Personality

Du Busi is loud, proud, combative, and openly delighted by exceptional talent. He treats Huo Yuhao’s arrival as grounds for the entire Body Sect to celebrate and immediately decides that the sect should emerge from seclusion. He dislikes empty ceremony, but takes the sect’s inheritance and future seriously 19 20.

His teaching combines harsh expectations with extensive personal support. He promises grueling training, demands tournament success, and refuses to let Huo Yuhao waste his potential. At the same time, he secures cultivation resources, supervises dangerous research, and insists that Huo Yuhao ask the sect and empire for help rather than experiment recklessly 20 34 35.

Although protective and quick to anger, he can put practical benefits above old grudges. He allows Huo Yuhao to learn from Mu En despite their hostility and accepts the Snow Empress’s instruction when it offers a path beyond his cultivation bottleneck 26 96 99.

His pride in martial strength does not extend to abusing the helpless. During preparations for continental unification, he explicitly rejects mistreating civilians and prisoners as a disgrace to the Body Sect 313.

Abilities & Skills

Whole-Body Martial Soul

Du Busi’s martial soul is his own body, rather than a single organ. Its unusual evolution arose from the interaction of his parents’ poison and detoxification abilities 26 95.

  • Possesses immense physical strength and durability; Huo Yuhao piercing his skin is enough to impress him 19.
  • Crushes a captured Soul Guidance bomb barehanded while suppressing its explosion 30.
  • After reaching Limit Douluo, his punches fracture space 109.
  • Serious bodily injuries also damage the foundation of his martial soul, as shown after his battle with Mu En 26.

Life and Death Tribulation Poison

His life-bound poison combines Jade Phosphorous Serpent venom with the detoxifying power of a liver Martial Soul. These opposing forces sustain and restrain one another in a continuous cycle 95.

Property Effect
Against weaker targets The venom kills those weaker than its wielder 95.
Against comparable or stronger targets Traps victims between life and death, continually eroding their vitality and causing prolonged agony 95.
High-level threat Can endanger Super Douluos and Limit Douluos; Du Bisou’s application left Mu En with injuries that resisted healing for years 95.
Root treatment Requires flames capable of burning the soul 95.
Cultivation risk Forcibly separating venom from detoxification destroys their balance and can make the poison run out of control 95.
Covert application Used to make a Body Sect infiltrator’s staged death convincing during Heaven Dou’s operation against Dai Hao 131 160.

Yin-Yang Complementary Dual Soul Cores

His first Soul Core represents life, vitality, and physical strength; his second draws upon the death aspect of his poison. The breakthrough depends on introducing life into death and death into life, rather than isolating the two powers 99 107.

  • Produces greater destructive power than the mainstream Isotopic Resonance method 95.
  • Allows him to fight Chen Fuhai and the separately manifested Radiant Sacred Dragon simultaneously 109.
  • Isotopic Resonance was unsuitable for his established cultivation: changing paths would have been comparable to starting over from level 90 and would not fully express his poison’s power 95.

Second Awakening and Martial Soul Avatar

His gold-level second awakening manifests an enormous golden likeness of himself, which merges into his body to increase his strength 23.

  • Combines with his Martial Soul Avatar to create a colossal giant 294.
  • Can produce metallic-looking skin and overwhelming physical force 270.
  • Remains vulnerable to superior control abilities: Huo Yuhao’s domain restrains his fully transformed body until he can no longer sustain the Avatar 294.

Documented Soul Skills

Soul Ring Skill Documented Use
First Body of a Hundred Poisons Activated alongside his second, third, and fifth skills against Chen Fuhai’s ambush 109.

Fifth Ten Thousand Poisons Golden Body Contributes to a golden-bodied form covered in deadly poison, becoming an emerald-green poison demon giant 109.
Eighth Unnamed area attack Releases numerous green pillars containing Life and Death Tribulation poison; identified as his strongest area attack 109.

Spiritual Power and Body Sect Instruction

  • Repels Huo Yuhao’s surprise Soul Shock with his own spiritual power and recognizes the future potential of mental-attribute skills 19.
  • Personally teaches Huo Yuhao the Secret of the Body, including the sect’s guarded Second Awakening method 35.
  • Performs the Body Sect Battle Dance, whose movements display fundamental applications of Body Martial Soul power 20.
  • Calls for research into flight through spiritual power so that younger Body Sect members can overcome their mobility limitations 97.

Equipment / Weapons / Items

  • Sealing God Platform — Holds the sealed Radiant Sacred Dragon. Du Busi lends it to Huo Yuhao, allowing him and Electrolux to investigate and discover Mu En’s soul 110 183.
  • Body Sect Master’s Token — Emblem of sect leadership, containing former leaders’ spiritual imprints and authority over the sect’s formation and resources. He transfers it to Huo Yuhao during the succession ceremony 294.
  • Emergency communication jade — Used to maintain emergency contact with Di Tian, whom he initially knows as Gu Tian 180.
  • Heavenly Scale Ancient Halberd — borrowed — Initially rejects him during examination. Much later, Huo Yuhao throws it to him in battle, and he uses its power to split the Bone Dragon King in two; he is not a trained halberd specialist 52 271.

Background / History

Family Origins and Du Bisou’s Death

Du Busi and his elder twin brother, Du Bisou, were born with life-bound poison. Their father possessed the Jade Phosphorous Serpent Martial Soul; their mother was a Body Sect disciple whose liver Martial Soul had exceptional detoxifying power. The combination produced whole-body Martial Souls carrying the Life and Death Tribulation poison 95.

Their paternal line originally used the surname Dugu. Its ancestor was an orphan adopted by Dugu Yan, not a blood descendant of the ancient Poison Douluo. When twins were born into a lineage that had traditionally produced only one heir per generation, their father changed the surname to Du because “poison was no longer alone” 95.

Mu En killed Du Bisou, whose final attack inflicted lasting poison injuries on him. The Body Sect subsequently sealed its gates for years. Du Busi continued to grieve his brother and sought both revenge and a successor capable of securing the sect’s future 20 23 24.

Recruiting Huo Yuhao and Reopening the Sect

After hearing about Huo Yuhao through Xue Xin, Du Busi rushes to Di’ao Academy. He examines the boy’s twin martial souls, tests his abilities, and is particularly impressed by Spiritual Detection Sharing and an ice-dragon attack capable of breaking his skin 18 19.

He takes Huo Yuhao to the Body Sect, accepts him as his personal disciple, and announces the sect’s emergence from seclusion. At the celebration, he promises to obtain Shrek Academy’s ultimate-attribute cultivation manual as an apprenticeship gift 20.

Confrontations with Shrek Academy

Du Busi leads the Body Sect against Shrek, publicly demanding redress for Heaven Dou while privately seeking the manual for Huo Yuhao. He fights Mu En, sustains serious injuries, and helps force negotiations after Xuan Zi is captured 22 23 24.

Mu En ultimately allows Huo Yuhao to study the manual in the Sea God Pavilion for three days under controlled conditions. Du Busi accepts the accompanying arrangements, including sealing Xuan Zi’s Soul Power 25.

After learning how powerful the Evil Soul Masters have become, Du Busi returns to Shrek with the emperor’s summons. He displays Nightmare Douluo’s mutilated corpse, defeats Xuan Zi’s attack, and threatens to revoke Shrek City’s self-government unless the academy joins the extermination campaign 64 65.

Breaking Through to Limit Douluo

Huo Yuhao brings Du Busi to the Far North to seek the Snow Empress’s guidance. Du Busi agrees to conditions sworn upon their Soul Cores, including her visit to the Body Sect 95 96.

Her explanation helps him recognize that his poison already embodies the balance required for Yin-Yang Complementarity. After more than two months in seclusion, he successfully forms his second Soul Core and reaches Limit Douluo 99 107.

He subsequently battles Chen Fuhai, whom he believes to be Mu En, and the Radiant Sacred Dragon together. His new strength enables him to injure Chen Fuhai and poison the dragon despite their combined attacks 109.

Imperial Strategy and Huo Yuhao’s Succession

Du Busi participates in Heaven Dou’s political and military planning, including a deception intended to undermine Xu Jiawei’s trust in Dai Hao. He supplies the poison needed for an infiltrator’s feigned death 131 160.

At the Soul Master Tournament, he exposes records of Ma Xiaotao’s evil fire harming and killing students. Following the Azure Dragon Seven Lodges’ victory, he appoints Huo Yuhao as the Body Sect’s Young Sect Master 164.

When Electrolux uncovers Mu En’s soul, Du Busi learns that Chen Fuhai had seized Mu En’s body. He agrees to help destroy the Golden Tree in exchange for Shrek’s accumulated knowledge and secret techniques 183.

His support increasingly extends to Huo Yuhao’s proposed cooperation between humans and soul beasts. After Huo Yuhao defeats ten Soul Saints in a test, Du Busi removes the sect and empire’s restrictions on his movements and invites him to challenge for sect leadership whenever ready 187 219.

Later Battles and Retirement from Leadership

During the Dou Ling campaign, Du Busi occupies the Offering Hall’s Titled Douluos above Dragon Head Platform. Against the Holy Spirit Cult, he overwhelms the newly advanced Zhongli Wu and later destroys the Bone Dragon King with Huo Yuhao’s borrowed halberd 255 270 271.

Recognizing Huo Yuhao’s growing superiority, he supports Qi Theory as a new direction for the Body Sect and calls for the succession to proceed 272 293.

In their public duel, Huo Yuhao breaks through his attack and immobilizes his full Martial Soul Avatar with an azure-dragon domain. Du Busi accepts defeat without resentment, kneels before his disciple, and presents the Sect Master’s Token. He remains involved afterward, supporting the new path while insisting that the sect preserve its standards toward civilians and prisoners 294 304 313.

Relationships

  • Huo Yuhao — Personal disciple and eventual successor. Du Busi secures his training and resources, champions his innovations, and willingly acknowledges him as sect master after losing their duel 20 34 293 294.
  • Du Bisou — Deceased elder twin brother. Shared his unusual Martial Soul and poison; his death at Mu En’s hands shaped Du Busi’s long-standing grief and hostility toward Shrek 24 95 107.
  • Snow Empress — Cultivation benefactor and ally. Her guidance resolves his Soul Core bottleneck; he thanks her formally before entering breakthrough seclusion 96 99.
  • Mu En — Former enemy responsible for Du Bisou’s death. After the truth about Chen Fuhai emerges, Du Busi makes an agreement with Mu En’s surviving soul 24 183.
  • Xue Heng — Heaven Dou emperor and political partner. Du Busi acts under imperial authority against Shrek and assists the empire’s covert strategy 65 131.
  • Long Aotian — Body Sect junior whose individual training Du Busi personally oversees 119.
  • Su Tong — Huo Yuhao’s companion, whom Du Busi protects alongside his disciple in the Far North. He also proposes her appointment as an Azure Dragon Guard deputy captain 49 96.
  • Di Tian / Gu Tian — Initially known to him through the supposed secluded Gu Family. They maintain emergency contact; Huo Yuhao later reveals his ties to Star Dou to the leadership 110 180 231.
