Yu Xiaogang

Biodata

Power Progression

Background / History

Yu Xiaogang grew up in the Blue Lightning Tyrant Dragon Sect. At six, he awakened Luo Sanpao with only half a level of innate Soul Power. Rejection and humiliation within the sect drove his ambition to become a Titled Douluo and overturn others’ judgment of him 15.

Despite his limited cultivation, he established a reputation as a Martial Soul theorist. He published the Ten Core Competencies of Martial Soul and the Soul Ring Absorption Limit Theory, presenting them as contributions to ordinary Soul Masters. He also spent more than ten years at Nuoding Academy without teaching a single class. Tang San became his disciple there after accepting his claims of expertise 20 21 25.

Spirit Hall’s destruction of his sect killed his father, mother, and eldest brother. As one of the surviving direct descendants, Yu Xiaogang became determined both to destroy Spirit Hall and to rebuild the Blue Lightning Tyrant Dragon Sect 10 21.

By the Heavenly Screen’s appearance, he was in Heaven Dou Imperial City among Tang San, the Shrek group, and the Seven Treasure Glazed Tile Sect’s leaders. His public identification on the screen named him Chief of Soul Masters of the Heaven Dou Empire 1 10.

Appearance

Yu Xiaogang is repeatedly described as having a stiff, rigid, or “zombie-like” face 9 17 20.

• Hair: A short crew cut before the Heavenly Screen’s lightning strike burned it away 25.
• Characteristic posture: Frequently clasps his hands behind his back while delivering judgments 3 15 18.
• After punishment: Temporarily left with blackened skin, charred clothing, and smoke coming from his mouth 25.

Personality

Yu Xiaogang places great importance on his reputation as Grandmaster. He delivers uncertain conclusions with absolute confidence and reacts angrily when contradicted. After Shi Hao’s strength challenges his assumptions, he blames Qian Renxue for misleading him; when Ma Hongjun questions his interpretation of the Willow Deity’s intervention, he treats the suggestion as an attack on his authority 6 18.

His childhood humiliation fuels both his desire for strength and his jealousy of exceptional talent. Qian Renxue’s Six-Winged Angel Martial Soul and innate level-20 Soul Power provoke resentment, while her acquisition of a Supreme Bone makes him wish that he had been transported to Stone Village instead 15 19.

His public concern for commoner Soul Masters conflicts with his private priorities. He considers valuable cultivation knowledge a resource for his own sect and looks down on commoners seeking his help. His hatred of Spirit Hall also shapes his public statements: he uses the Heavenly Screen to win supporters and turn opinion against it 10 20 21.

Abilities & Skills

Luo Sanpao

Luo Sanpao is Yu Xiaogang’s mutated Martial Soul, originally associated with his weak innate aptitude 15 16.

• Dragon origin: Eventually possessed a Golden Sacred Dragon origin and approached evolution into that form 25.
• Forced regression: The Heavenly Screen extracted that origin, removing its golden scales and leaving a bloated purple pig-like form 25.
• Post-punishment condition: Yu Xiaogang recognizes it as a pig-like beast resembling an ordinary Beast Martial Soul 26.

Martial Soul Theory

Yu Xiaogang’s standing rests on his theoretical reputation rather than demonstrated high-level combat strength 16 24.

• Published works: The Ten Core Competencies of Martial Soul and Soul Ring Absorption Limit Theory 20.
• Research habits: Claims decades of experience writing experimental notes; his ability to transcribe observed material is explicitly demonstrated 20.
• Misjudged Soul Beast age: Incorrectly assessed the Man Faced Demon Spider whose Soul Ring Tang San absorbed, nearly causing Tang San’s death 25.
• Incomplete Soul Ring knowledge: Did not know about the Soul Shock accompanying a ten-thousand-year Soul Ring 25.
• Flawed advice for Tang San: The poisonous Soul Rings chosen for Blue Silver Grass lost their toxin benefits when Tang San’s Blue Silver Emperor bloodline awakened and purified them 25.

Stone Village Body Tempering Fist

Yu Xiaogang records the technique from the Heavenly Screen, but recording it does not establish mastery 20.

• Recorded requirements: Physical postures and movements must be coordinated with the correct breathing rhythm 20.
• Practical limitation: Finds the technique difficult and acknowledges that it requires further practice 20.
• Intended recipients: Plans to reserve his notes for Yu Tianheng, Yu Tianxin, and other surviving sect members 21.
• Public position: Claims the record is incomplete and unsafe to distribute, despite having told his companions that he finished recording it 20 21.

Public Persuasion

Yu Xiaogang uses Heavenly Screen comments to promote his authority and influence continental opinion 10 16.

• Warns viewers against hastily practicing another world’s cultivation method 10.
• Presents himself as a responsible researcher while using the issue to recruit support against Spirit Hall 10 20.
• Argues that retaining Martial Souls might allow future integration of the two cultivation systems; this remains his proposal, not a demonstrated achievement 16.

Story Role / Major Arcs

The Heavenly Screen’s Arrival

• Identifies the enormous golden screen as a divine miracle after finding no comparable phenomenon in the ancient texts he has read 1.
• Rushes to Tang San in alarm when using the Purple Demon Eye against the screen leaves his disciple screaming and bleeding from the eyes 2.
• Responds to the revelation of Qian Renxue’s survival in another world with open hatred 3.

Misjudging Stone Village

• Dismisses Shi Yunfeng’s claim that Qian Renxue’s Soul Saint body is weaker than a one-year-old child’s, judging Stone Village’s inhabitants by their animal-skin clothing and stone houses 4.
• After the child’s strength becomes evident, insists that Qian Renxue must have lost her cultivation rather than accepting his earlier judgment was wrong 6.
• Ridicules six-year-old Shi Yan’s wish to join the hunting party. The revelation that Shi Yan can exert 108,000 jin with one arm directly undermines his assessment 9.

Opposing Qian Renxue’s Change of Cultivation

• Condemns Shi Yan for comparing Soul Power to impurities and argues that the Soul Master system retains value despite differences between worlds 15.
• Publicly warns that destroying Qian Renxue’s inherited Martial Soul could damage her origin and prevent her from combining the two systems 16.
• Dismisses the Willow Deity as a charred tree whose lingering lightning might merely frighten beasts 17.
• Declares Qian Renxue “ruined” when her Martial Soul dissolves, rejecting Ma Hongjun’s suggestion that it is being transformed into another form of power 18.
• Reacts with intense envy when the intervention instead grants her a Supreme Bone talent 19.

Withholding the Body-Tempering Technique

• Privately confirms that he has recorded Stone Village’s technique, then tells the public that his record is unfinished 20.
• Defends withholding it on the grounds that individuals have no obligation to share their work for free and should prioritize their clans and sects 21.
• His explanation begins to damage Liu Erlong’s belief that he sincerely champions commoner Soul Masters 21.

The Green-Scaled Eagle and Heavenly Screen Punishment

• Predicts that Shi Yan cannot defeat the Green-Scaled Eagle, applying Douluo team-combat assumptions to Stone Village’s cultivators 22.
• Watches Shi Yan overpower and subdue it. The repeated damage to his reputation deepens his hatred of Shi Yan 23.
• Enters the Heavenly Screen’s quiz and wagers at maximum stakes, asserting that the eagle’s scales prove its bloodline primarily comes from a True Dragon-type beast 25.
• Rejects the correct answer involving a Heavenly Peng and accuses the screen of deception. A divine lightning strike punishes this challenge, with a warning that another offense will destroy his body and soul 25.
• Separately receives the wrong-answer penalty: removal of Luo Sanpao’s Golden Sacred Dragon origin 25.
• After healing, attempts to smash his head against the ground in despair. Liu Erlong and Flender stop him and suggest that future quiz rewards might restore Luo Sanpao, renewing his determination to answer again 26.

Relationships

• Tang San — Disciple. Yu Xiaogang shows concern for his injuries, but Tang San privately loses faith in his expertise after several dangerous mistakes. Tang San continues displaying respect to preserve his own public image 2 25.
• Liu Erlong — Younger female cousin and devoted romantic admirer who has waited twenty years for him. His treatment of commoners shakes her admiration, but she continues supporting him and prevents his self-destructive response to Luo Sanpao’s regression 21 25 26.
• Flender — Close supporter who frequently accepts his reasoning and helps obtain treatment after his punishment 17 18 26.
• Ning Fengzhi — Political ally who privately doubts his competence. His praise that “whoever gains the Grandmaster gains the world” was intended to help win over Tang San 6 16 25.
• Ma Hongjun — Asks for help learning the recorded body-tempering technique and questions whether the Willow Deity transformed Qian Renxue’s Martial Soul; the latter suggestion earns an angry rebuke 18 20.
• Yu Tianheng and Yu Tianxin — Nephews for whom he intends to reserve the Stone Village Body Tempering Fist as part of rebuilding the sect 21.
• Xue Beng — Publicly praises his wisdom and joins his Heavenly Screen attacks on Qian Renxue 10 16.
• Qian Renxue — Enemy and object of jealousy. Her exceptional aptitude and successful transition to another cultivation system repeatedly contradict his predictions 15 18 19.
• Shi Yan — Target of repeated dismissive judgments. Shi Yan’s achievements undermine Yu Xiaogang’s authority until he privately wishes for the child’s death 9 23.
• Qian Daoliu — Hostile observer who plans to expose Yu Xiaogang’s background once his predictions can be conclusively disproved 16.
• Spirit Hall — Sworn enemy responsible for destroying his sect and killing close family members 10.
