Background / History

Yu Xiaogang is a Shrek Academy-affiliated Martial Soul theorist who regards himself as the continent’s foremost authority on Martial Souls. He claims authorship of the Ten Core Competencies of Martial Soul and repeatedly invokes his reputation as the “Grandmaster of Martial Soul Theory” when challenged 1 4.

When the Sky Screen begins broadcasting across eras, Yu immediately starts advising Ye Chen despite not recognizing either the Three-Eyed Golden Lion or Heavenly Snow Woman. He dismisses both as likely “trash Martial Souls,” recommending that the former follow a support path and the latter a control path 1. His advice draws immediate opposition from future-era Soul Masters, beginning a prolonged series of livestream arguments.

The screen repeatedly exposes phenomena outside Yu’s established framework: unusually old Soul Rings, multi-attribute Martial Souls, million-year Soul Rings, Battle Armor, Soul Tools, Ferocious Beasts, and Soul Spirits. Rather than revise his conclusions, he generally insists that the evidence is impossible or that his theories remain correct 3 7 14 32 36.

Ning Rongrong eventually identifies the anonymous “theory master” as Yu Xiaogang from his fixation on the Blue Lightning Tyrant Dragon and his claims of theoretical mastery. Her public attack forces him to conceal his cultivation and fuels his determination to identify and retaliate against his critics 27.

Personality

Yu Xiaogang is proud, defensive, and intensely dependent on his intellectual reputation. He treats disagreement as disrespect toward his status, often demanding to know whether critics are qualified to challenge a man who “taught a god” 1 4.

His confidence masks a pronounced insecurity over his mutated Martial Soul and limited cultivation. He reacts especially badly to being called “trash,” refuses to disclose his age or Soul Power when challenged, and records the chat identification numbers of those who humiliate him 5 27.

He is also stubbornly attached to familiar institutions and legacies. He exalts Tang San, the Blue Lightning Tyrant Dragon, control-type Soul Masters, and conventional Soul Ring cultivation even when later-era evidence contradicts his assumptions 7 14 15 23.

Abilities & Skills

Martial Soul Theory

Yu’s principal expertise is his body of Martial Soul theory, particularly the Ten Core Competencies of Martial Soul. His interpretations are influential in his own era but are repeatedly challenged by Soul Masters from later eras.

Theory or Claim	Yu Xiaogang’s Position	Shown Counterexample
Soul Ring absorption limits	A first Soul Ring should be limited to a little over 400 years and a third Soul Ring to roughly 1,700 years.	Ye Chen’s two purple rings and black third ring; Tang Wulin’s thousand-year first ring; Qian Gu Dieting’s nine hundred-thousand-year rings 3
Martial Soul attributes	Most Martial Souls have only one attribute; mutations may have two.	The Three-Eyed Golden Lion possesses spiritual, light, and fire attributes, while Gu Yue confirms she has six known attributes 7
Combat roles	Control-type Soul Masters should dominate the battlefield and defeat assault-types at the same level.	Yun Ming argues that assault-types are the mainstream and that control-types cannot inherently defeat stronger opponents of equal rank 7
Soul-skill selection	A Soul Master should either compensate for weaknesses or specialize in a strength.	Wu Zhangkong criticizes the rule as too simplistic because choices must suit the individual Martial Soul 7
Soul Tools	Only Soul Rings and Soul Bones meaningfully improve a Soul Master’s power.	Battle Armor, Mecha, and advanced Soul Tools can enhance combat ability on a comprehensive scale 14
Support Martial Souls	The Seven Treasure Glazed Tile Pagoda is the strongest support Martial Soul.	Later-era Soul Masters cite the Wish Angel Martial Soul as superior 18

Luo Sanpao

Yu Xiaogang’s Martial Soul is Luo Sanpao, a mutation related to the Blue Lightning Tyrant Dragon lineage. He publicly insists on treating it as a Blue Lightning Tyrant Dragon Martial Soul, despite its altered form and limited cultivation results 27.

• Possesses a trace of Light Sacred Dragon bloodline 27.
• Was the basis of Yu’s long-term claim that his cultivation bottleneck came from a flawed Martial Soul 5.
• Leaves him highly sensitive to insults toward weak or mutated Martial Souls, despite his own tendency to disparage unfamiliar ones 1 27.

Relationships

• Tang San — Yu claims to have guided Tang San to godhood and believes Tang San respects him “like a father.” Tang San’s Immortal Herbs helped Yu reach three rings 4 22 27.
• Liu Erlong — Closely associated with Yu; she punches him after noticing his obvious reaction to Bibi Dong’s appearance 5.
• Bibi Dong — Yu retains a visible interest in her appearance while also celebrating Spirit Hall’s eventual destruction 2 5.
• Ning Rongrong — Identifies Yu through the anonymous chat and publicly attacks his theories, age, cultivation, and self-image 27.
• Xu Xiaoyan — A frequent livestream critic who repeatedly challenges his theories and mocks his inability to explain later-era knowledge 1 3 32.
• Yun Ming — One of Yu’s strongest opponents in the chat; repeatedly rebukes his advice on Martial Soul development, combat roles, and bloodline superiority 1 7 17 27.
• Long Yeyue — Challenges his claim that the Blue Lightning Tyrant Dragon is the strongest beast Martial Soul; Yu insults her Light Sacred Dragon without understanding its connection to his own lineage 15 27.

Story Role / Major Arcs

• Sky Screen commentator — Enters the cross-era livestream debate by misidentifying Ye Chen’s Martial Souls and prescribing unsuitable development paths 1.
• Theory repeatedly challenged — His Soul Ring limits, single-attribute principle, control-type preference, and skill-selection rules are disputed by future-era experts 3 7.
• Technological ignorance exposed — Cannot explain Soul Tools, Battle Armor, or their role in high-level Soul Master combat 14.
• Blue Lightning Tyrant Dragon disputes — Repeatedly declares the Blue Lightning Tyrant Dragon the world’s strongest beast Martial Soul, provoking En Ci, Long Yeyue, Yun Ming, and others 15 17 27.
• Freshman Assessment commentator — Makes confident tactical predictions about Ye Chen’s team, including claims that they cannot defeat Xie Huanyue’s Rubber Elephant defense; the team repeatedly proves him wrong 19 21 22.
• Identity exposed — Ning Rongrong deduces his identity and publicly humiliates him, revealing that he is only a three-ring Soul Master despite his grand claims 27.
• Far North ignorance — Fails to recognize the Ten Great Ferocious Beasts, the Three Great Kings of the Far North, million-year Soul Rings, and the Soul Spirit system 31 32 36.
