Yu Xiaogang

Biodata

Background / History

Yu Xiaogang’s martial soul mutated from the Blue Lightning Tyrant Dragon into the Radiant Sacred Dragon. The narration identifies this as a powerful, beneficial mutation, but states that he failed to develop Luo Sanpao into a true Radiant Sacred Dragon. Yu Xiaogang instead believes his martial soul is responsible for his limitations 16.

Still at rank twenty-nine after passing fifty, he treats martial soul research as his remaining source of dignity. He withdrew from the wider Soul Master World to Nuoding City, where his friendship with the academy headmaster secured him a teaching position. His ambitions include making his former detractors acknowledge him as Grandmaster and taking revenge on the Blue Lightning Tyrant Dragon Clan 1 15 18.

His romantic history was shaped by Qian Xunji’s mental suggestion. To awaken the Rakshasa God’s origin power within Bibi Dong, Qian Xunji made her fall in love with Yu Xiaogang, then made Yu Xiaogang fall in love with Liu Erlong. The resulting betrayal was intended to provoke intense negative emotions in Bibi Dong 12.

Personality

Yu Xiaogang craves recognition but reacts badly to challenges. When Chen Ci questions his treatment of a mutated martial soul, he responds with anger and attempts to impose discipline through academy authority. He likewise invokes his status as the headmaster’s honored guest when Hu Liena and Gu Yuena refuse to become his disciples 1 14.

His teaching is subordinated to protecting his reputation. He plans to test theories on Chen Ci before applying them to Tang San, treating Chen Ci as expendable while hoping Tang San will become a Super Douluo. When evidence contradicts him, he recasts earlier advice as a test of character or claims knowledge he had not demonstrated 1 3 17.

His outward deference can conceal resentment. After Tang Hao leaves him poisoned in the forest, he privately plans to obtain the Clear Sky Manual and then reveal Tang Hao’s location to Bibi Dong. Public criticism eventually overwhelms him enough to make him flee before his disciple’s duel concludes 5 18.

Abilities & Skills

Luo Sanpao

• Manifestation: Summons a purple, piglike creature that can move independently and respond to spoken commands 1 2.
• Undeveloped potential: Luo Sanpao possesses Radiant Sacred Dragon potential, which Yu Xiaogang has not realized 2 16.
• Bloodline vulnerability: Chen Ci’s Golden Dragon King pressure frightens Luo Sanpao into approaching Chen Ci affectionately and later disregarding Yu Xiaogang’s attack command 2.
• Imperfect control: Luo Sanpao eventually returns when called, but its fear of Chen Ci overrides obedience during combat 2.

Earth-Shattering Luo Sanpao

• Activation: Yu Xiaogang feeds Luo Sanpao a radish before ordering, “Fart like thunder—Earth-Shattering Luo Sanpao!” 2.
• Effect: Releases an explosive discharge of foul-smelling smoke. Its blast knocks both Yu Xiaogang and Tang San unconscious during the academy confrontation 2.
• Hazard: The discharge affects bystanders and can strike Yu Xiaogang himself if Luo Sanpao turns away from the intended target 2.
• Demonstrated threat: Chen Ci recalls that even hundred-year soul beasts must keep their distance from Luo Sanpao’s attacks 15.

Martial Soul Theory and Instruction

• Recognition of twin martial souls: Identifies Tang San as possessing twin martial souls, a point Tang Hao initially regards as evidence of some competence 1 2.
• Preferred training approach: Directs Blue Silver Grass users toward control and support, emphasizing toughness and battlefield restraint 1.
• Source of knowledge: His theories are described as stolen from Spirit Hall; he later publicly admits that they came from Spirit Hall 1 18.

Relationships

• Tang San — Favored disciple and intended proof of his theories. Yu Xiaogang promises him all his knowledge and resources, later calling him his “last everything” 3 23.
• Chen Ci — Forcibly recruited disciple turned opponent. Yu Xiaogang intends to use him as a test subject, but Chen Ci publicly challenges his instruction and exposes weaknesses in his claims 1 17 18.
• Bibi Dong — Former romantic attachment and hoped-for source of restored status. After breaking Qian Xunji’s suggestion, she loses all affection for him and rejects his familiar address of “Dong’er” 12 23.
• Liu Erlong — The woman Qian Xunji’s mental suggestion made him fall in love with as part of the scheme against Bibi Dong 12.
• Tang Hao — Tang San’s father, whom he addresses respectfully as “Your Excellency Haotian.” He secretly resents Tang Hao for abandoning him while poisoned 5.
• Nuoding Academy headmaster — Friend and institutional supporter who intervenes during the confrontation with Chen Ci and gives him opportunities to address the academy crowd 2 15 16.
• Hu Liena and Gu Yuena — Prospective disciples who immediately refuse him. Both subsequently express discomfort with his behavior 14 15.

Story Role / Major Arcs

Conflict over Chen Ci’s Training

Yu Xiaogang assigns Chen Ci a support role for Tang San and recommends identical soul-ring choices for their Blue Silver Grass despite Chen Ci’s visible mutation. When challenged before other students, he summons Luo Sanpao to subdue Chen Ci rather than expel a valuable test subject 1.

Chen Ci’s Golden Dragon King pressure disrupts the punishment. Luo Sanpao redirects its attack toward Yu Xiaogang, knocking him and Tang San unconscious. After retreating, Yu Xiaogang accepts Tang San’s offer to vindicate his theories through a future duel 2 3.

Soul Hunting and Poisoning

While accompanying Tang San on a soul hunt, Yu Xiaogang suffers Mandala Snake poisoning. Tang Hao arrives and takes Tang San away without first securing Yu Xiaogang’s safety. Unable to leave the forest promptly, Yu Xiaogang drags himself into a dark, damp hiding place to conceal his human scent from soul beasts 5.

Public Exposure at Nuoding Academy

After failing to recruit Hu Liena and Gu Yuena, Yu Xiaogang promotes a duel between Tang San and Chen Ci as a demonstration of his research. He initially expects Tang San’s evolved Blue Silver King to overpower what he considers Chen Ci’s ordinary mutation 14 15 16.

When the Blue Silver King submits, he claims that he had recognized Chen Ci’s Blue Silver Emperor all along and that his earlier instruction was merely a character test. Chen Ci’s thousand-year first ring then provokes further scrutiny. Yu Xiaogang’s insistence that his theories cannot be wrong because they came from Spirit Hall exposes their source, and he flees amid accusations of fraud 17 18.

Final Audience with Bibi Dong

Yu Xiaogang visits Bibi Dong hoping their past affection will help him regain his standing, potentially by returning to Spirit Hall as an elder. Instead, she explains that their former relationship resulted from someone else’s scheme and condemns his stolen research 23.

He then requests the method for cultivating twin martial souls for Tang San and threatens to destroy Spirit Hall if she harms his disciple. Bibi Dong gives him the method Chen Ci previously described to her. Unknown to Yu Xiaogang, Chen Ci’s explanation was fabricated to justify attaching rings to both of his martial souls simultaneously; Chen Ci expects the same approach could cripple Tang San. Yu Xiaogang departs in dejection 23.
