Yu Xiaogang

Biodata

Background / History

Yu Xiaogang is the son of Yu Yuanzhen, head of the Blue Lightning Tyrant Dragon Clan. His mutated Martial Soul left him with poor talent and little recognition within his family. He eventually left the clan and spent many years away without visiting his father 17.

In his youth, he and Bibi Dong developed romantic feelings. Their relationship ended because of their respective identities, but Bibi Dong continued to idealize his determination and theoretical research long afterward 15 17.

While traveling the continent, Yu Xiaogang helped form the Golden Iron Triangle. He and fellow member Liu Erlong fell in love without knowing they were cousins. On their wedding day, his second uncle revealed their blood relationship, after which Yu Xiaogang left Liu Erlong. He later justified leaving as an attempt to protect her reputation 17 18.

By the opening of the livestream, he is Tang San’s teacher. Tang San and Xiao Wu have finished their time at Nuoding Academy and are preparing to enter Shrek Academy; Yu Xiaogang intends to follow them there 2.

Personality

Yu Xiaogang is intensely proud of his reputation as a theorist. He regards the livestream as an opportunity to publicize his knowledge before the entire continent, impress Bibi Dong and his father, and vindicate himself against those who previously dismissed him 2.

He reacts poorly to criticism, treating failed predictions as personal attacks rather than reasons to reconsider his assumptions. After Liang Hao awakens exceptional Martial Souls, Yu Xiaogang privately blames him for mutating and embarrassing him. When challenged by younger viewers, he questions their right to criticize him and threatens retaliation 4 7.

His concern for prestige develops into open malice. He hopes Liang Hao will die attempting to absorb an older Soul Ring so that his own theory will appear correct. Although he privately recognizes the truth of Liang Hao’s later criticisms, he refuses to acknowledge them publicly and waits for another opportunity to restore his standing 14 18.

He also relies heavily on influential supporters. Bibi Dong’s defense reassures him after his first failure, while his eventual revenge plans depend on Liu Erlong, Flender, Tang San, and the students he hopes to train at Shrek Academy 4 29.

Abilities & Skills

Martial Soul Research

Yu Xiaogang published the Ten Core Competencies of Martial Soul, the foundation of his reputation as a theoretical authority. His work addresses Martial Soul inheritance, cultivation, and Soul Ring absorption, but the livestream exposes substantial weaknesses in both his research and its application 2 14 17.

• Research sources: He has drawn extensively on earlier theoretical texts. Liang Hao criticizes him for presenting established knowledge as his own achievement; Bibi Dong acknowledges that much of his work is either common knowledge or incorrect 10 17.
• Verification problems: Bibi Dong concedes that he published Soul Ring age limits without properly verifying them 17.
• Limited adaptability: He treats Liang Hao’s unusual results as challenges to his authority rather than evidence that his rules require qualification 14 18.

Teaching

Yu Xiaogang instructs Tang San and helped select the Soul Ring that grants his First Soul Skill, Entanglement. Tang San initially credits his teacher with making his supposedly poor Martial Soul useful, but later questions that guidance after comparing his own first skill with Liang Hao’s Five Elements Fusion 2 24.

• Claims that his instruction is necessary for Liang Hao to realize his potential and that his teaching surpasses Bibi Dong’s 6.
• Plans to train Flender’s talented students as a means of retaliating against Liang Hao 29.

Combat Limitations

• His Martial Soul is described as weak, and his Soul Power as lacking 15.
• He admits that, at fifty years old, he still cannot defeat a Three-Ring Soul Elder 27.
• No personal cultivation breakthrough or named combat technique is documented in the provided chapters.

Story Role / Major Arcs

Joining the Livestream

When the light screens appear, Yu Xiaogang recognizes their ability to connect distant Soul Masters and urges Tang San to investigate the instance before becoming distracted by personal revelations. The cross-era audience also reveals that his title remains known thousands of years in the future, which he interprets as proof that later generations recognize his theories 1 16.

Failed Predictions

Yu Xiaogang becomes a recurring critic of Liang Hao’s speedrun. Each new prediction offers him a chance to recover his reputation, but Liang Hao’s results repeatedly contradict him.

Exposure of His Past and Research

Inside the instance, Bibi Dong cites Yu Xiaogang’s theories to discourage Liang Hao from attempting a thousand-year First Soul Ring. Liang Hao responds by attacking the originality and accuracy of his work, then recounts his abandonment of Liu Erlong and estrangement from his father 15 17.

The broadcast turns this confrontation into a public reckoning across multiple eras. Yu Xiaogang stops answering the chat because he knows the disclosures are true and expects further ridicule. Privately, he insists that everyone is targeting him and vows to prove his theories correct 18.

The fallout reaches his family and historical reputation:

• Bibi Dong begins questioning the idealized image of him she has maintained for years 18 19.
• Yu Yuanzhen decides that he must have his son brought back to prevent further damage to the clan’s name 19.
• Mu En, his descendant in the Douluo II era, resolves to reduce Shrek Academy’s promotion of him as an exemplary teacher 19.

Retaliation Plans

After Liang Hao defeats Yan, Yu Xiaogang vows to have him killed. He resumes his plan to reach Shrek Academy, intending to use Flender’s students against Liang Hao and punish Ma Hongjun and Oscar once he gains authority over them 29.

Relationships

• Tang San — Disciple and early defender. Tang San threatens revenge for the insults against his teacher, but later begins doubting Yu Xiaogang’s judgment and Soul Ring guidance 19 24 29.
• Bibi Dong — Former romantic partner and influential supporter. She initially defends him even at the expense of her own credibility, but his repeated failures gradually replace her admiration with doubt and frustration 7 14 24 26.
• Liu Erlong — Cousin and former fiancée. Despite his departure on their wedding day, she remains fiercely protective and threatens Liang Hao for humiliating him 17 19.
• Yu Yuanzhen — Father and Blue Lightning Tyrant Dragon Clan head. Their long estrangement worsens when the livestream publicly embarrasses the clan 17 19.
• Flender — Associate whom Yu Xiaogang counts among his supporters. Flender’s report of talented students at Shrek Academy becomes the basis of his latest plan to restore his standing 29.
• Liang Hao — Target of his criticism and eventual revenge plans. Liang Hao’s achievements undermine his theories, while his disclosures weaken Bibi Dong’s attachment to him 17 23 29.
• Ning Rongrong — Persistent critic who mocks his failed predictions and repeatedly calls on him to answer Liang Hao’s accusations. Yu Xiaogang privately threatens to destroy her sect 4 18.

• Mu En — Descendant who grew up with Yu Xiaogang’s celebrated historical image. The livestream leaves him ashamed of his ancestor and concerned about Shrek Academy’s reputation 19.
