Yu Xiaogang

Biodata

Background

Yu Xiaogang is the son of the Blue Lightning Tyrant Dragon Clan’s leader. His weak Martial Soul and stalled cultivation made him a disgrace in his family’s eyes. He left the clan to travel the continent and devoted himself to Soul Master theory, hoping to resolve the problem preventing his advancement 5.

In his youth, he was close to Flender and Liu Erlong. Flender withdrew from pursuing Liu Erlong because he believed she would be happy with Yu Xiaogang. However, Yu Xiaogang fled their wedding, leaving Liu Erlong to face the resulting rumors alone; the supplied passages do not explain why he left 42.

He later became Tang San’s teacher and cared for him for years. By the time he arrives at Shrek Academy, he treats Tang San’s level-29 cultivation as proof of his own theoretical expertise 5 6.

Appearance

• Initial appearance: A middle-aged man of average build, with stiff facial muscles and a dispirited bearing. He habitually approaches others with his hands behind his back 5.
• After his first expulsion: Returns with a shaved head, heavy stubble, and a greasy, unkempt appearance 27.
• Later appearance: Yu Tianheng sees him with a short crew cut and a weathered, stubbled face, contrasting sharply with his memories of a handsome, confident uncle 62.

Personality

Yu Xiaogang bases his self-worth on his reputation as a theorist. Although deeply sensitive about his low cultivation, he insists that his research is unrivaled and that even powerful Soul Masters should recognize him as “Grandmaster.” He initially assumes that correcting Chu Feng’s training methods will persuade Chu Feng and Shrek’s other students to become his disciples 5.

His attachment to that reputation becomes increasingly coercive. When Tang San hesitates to leave Shrek Academy with him, Yu Xiaogang invokes their years together and accuses him of betraying his master. He later uses similar accusations of ingratitude against Yu Tianheng when his nephew refuses to secure him a teaching position 6 62.

After repeated rejection, his stated concern for talented students gives way to deliberate retaliation. Unable to defeat Shrek Academy physically, he builds public support through free consultations and uses it to spread accusations against the academy. His private aim is to destroy the reputations of students he cannot recruit 41 42.

Flender remembers him as once confident and gentle, making his later hostility and vindictiveness particularly distressing to his former friend 7 41.

Abilities & Skills

Soul Master Theory

Yu Xiaogang has spent years studying Martial Souls, cultivation methods, and Soul Ring selection. Flender acknowledges that he possesses genuine knowledge, despite rejecting his conduct 41.

• Provides free advice about Martial Souls, suitable Soul Rings, and training to crowds in Suotuo City 41.
• Considers Soul Ring configuration his strongest subject and has proposed a theory concerning configuration limits 43.
• Claims authorship of the Ten Great Soul Master Theories 6 7.
• Previously advised Tang San to postpone adding Soul Rings to his second Martial Soul until reaching Titled Douluo, allowing for much older rings 87.
• Can evaluate unfamiliar proposals: he privately recognizes the validity of Chu Feng’s unconventional configuration and identifies weaknesses in the proposed solution for Luo Sanpao 46 47.

His expertise does not match his claims of universal authority. Chu Feng exposes his unwillingness to consider hypothetical Martial Souls, while his own research has failed to overcome his cultivation ceiling 45 46 47.

Luo Sanpao

Luo Sanpao is Yu Xiaogang’s Martial Soul. Its demonstrated offensive function involves fart-based attacks, which Yu Xiaogang considers using against Shrek’s gatekeepers before recognizing that their Soul Power exceeds his own 27.

• Its first Soul Ring is a hundred-year ring associated with a farting skill 47.
• Yu Xiaogang attributes his inability to reach level 30 to an innate Martial Soul defect 5 44.
• No cultivation breakthrough is documented; he remains level 29 in his later confrontation with Yu Tianheng 62 63.

Proposed Method for Breaking His Cultivation Ceiling

During their public contest, Chu Feng argues that Luo Sanpao is a mutated Martial Soul whose bloodline connection to the Blue Lightning Tyrant Dragon has been severed. His proposed configuration would reconnect that pathway temporarily rather than simply provide stronger attacks 47.

• Not an achieved advancement: The configuration is presented as a route Yu Xiaogang could have followed; he does not implement it in the supplied passages 47.
• Limitations: Yu Xiaogang points out that the temporary pathway could collapse, causing Martial Soul deterioration or Soul Power regression. Chu Feng accepts that the method would not permanently remove the underlying problem 47.

Training Methods

• Advocates running laps while carrying rocks as a means of strengthening Soul Masters’ bodies 5.
• Initially dismisses Chu Feng’s Martial Dao training as useless and harmful to the students’ development 5.
• Attempts to make obedience to his cultivation arrangements a condition of his involvement with Yu Tianheng’s team 64.

Story Role / Major Arcs

Rejection at Shrek Academy

After hearing about Chu Feng and Martial Dao from Flender, Yu Xiaogang visits Shrek Academy intending to assess Chu Feng and potentially recruit him and the other students as disciples. He interrupts training, condemns the methods in use, and offers to teach Chu Feng how Soul Masters should train 5.

Chu Feng challenges his authority by contrasting Tang San’s achievements with Zhu Zhuqing’s largely self-directed cultivation. Tang San also begins reconsidering how useful his teacher’s advice has actually been, particularly the earlier recommendation of Ten-Year Solitary Bamboo for his first Soul Ring 6.

When Yu Xiaogang refuses to leave, Chu Feng demonstrates his physical strength and orders him expelled. Yu Xiaogang pressures Tang San to accompany him, but Chu Feng’s barrier separates them and keeps Tang San at the academy. Flender subsequently upholds the expulsion 6 7.

Failed Return and Tang Hao’s Intervention

Yu Xiaogang returns to challenge Chu Feng to a contest of Soul Master theory, proposing that the loser leave Shrek Academy. Chu Feng refuses, and the gatekeepers carry Yu Xiaogang away before warning him against following them back 27.

Shortly afterward, Tang Hao introduces himself as Clear Sky Douluo and Tang San’s father, grabs Yu Xiaogang by his clothes, and flies away with him. Their subsequent conversation is not shown in the supplied passage 28.

Suotuo City Smear Campaign

Yu Xiaogang establishes a consultation platform in Suotuo Central Square, where free theoretical advice draws a substantial audience. Between consultations, he portrays Shrek Academy as a violent, academically incompetent institution that allows a twelve-year-old to teach 41.

He displays bruises while claiming that Shrek personnel beat him for offering to help. Ning Rongrong rejects this account, stating that they never struck him. Yu Xiaogang relies on his helpful public image to make bystanders accept his accusations and interpret Shrek’s response as further intimidation 41 42.

When confronted, he also suggests involving a Spirit Hall envoy. Flender recognizes that an investigation could give authorities already hostile to Shrek Academy a reason to act against it 43.

Public Theory Contest

Chu Feng challenges Yu Xiaogang to substantiate his accusations, and their confrontation becomes a Soul Ring configuration contest at the Suotuo Soul Master Lecture Hall. Yu Xiaogang agrees to stakes involving imprisonment if he loses 43 44 45.

By his next documented appearance, Yu Xiaogang has been released; the supplied passages do not detail his confinement 62.

Attempt to Enter Heaven Dou Royal Academy

Yu Xiaogang approaches Yu Tianheng with a plan to become a Heaven Dou Royal Academy teacher and train a team capable of defeating Shrek Academy at the Soul Master Tournament two years later. Yu Tianheng refuses, questioning both his qualifications and his ability to understand realms he has never reached 62.

Their dispute turns violent after Yu Xiaogang mocks his nephew’s defeat and relationship troubles. Yu Tianheng strikes him and threatens further injury, but a black-clad Titled Douluo intervenes, overpowers Yu Tianheng, and takes both men outside Suotuo City 63.

With the stranger’s backing, Yu Xiaogang demands admission to the academy and authority over Yu Tianheng’s training, threatening him with death by poison if he fails. He reluctantly agrees to conceal his identity. These arrangements remain a plan in the supplied passages; Yu Tianheng still has to resolve the obstacle posed by the team’s existing teacher, Qin Ming 63 64.

Relationships

• Tang San — Longtime disciple whom he cared for over several years. Tang San initially defends him out of gratitude, but loses his remaining goodwill after the smear campaign against Shrek Academy 6 41.
• Chu Feng — Rival whose teaching methods and theoretical achievements undermine his authority. Their conflict escalates from a failed recruitment attempt to expulsion, public slander, and a theory contest 5 6 41 47.
• Flender — Former close friend and companion. Flender chooses Shrek Academy’s future over accommodating him, and their friendship collapses after Yu Xiaogang attacks the academy’s reputation 7 41 42.
• Liu Erlong — Former intended bride. Yu Xiaogang abandoned their wedding, leaving her to endure public speculation alone 42.
• Yu Tianheng — Nephew who remembers benefiting from his childhood advice. Their reunion ends in violence and coerced cooperation over a proposed academy appointment 62 63 64.
• Tang Hao — Tang San’s father; forcibly takes Yu Xiaogang away after his second rejection at Shrek Academy 28.
• Black-clad Titled Douluo — Unnamed supporter who rescues him from Yu Tianheng and compels his nephew to accept his demands. The stranger also forces Yu Xiaogang to conceal his identity 63 64.
