Yu Xiaogang

Biodata

Power Progression

Background / History

Yu Xiaogang is a direct-line descendant of the Blue Lightning Tyrant Dragon Sect. Unable to advance beyond level twenty-nine, he built his public identity around Martial Soul theory and the title of Grandmaster. He presents Ten Core Competencies of Martial Soul as his masterpiece 19 20.

Bibi Dong and His Theoretical Reputation

Yu Xiaogang previously had a relationship with Bibi Dong. The Heavenly Screen reveals that she wanted to leave Spirit Hall to be with him, but Qian Xunji threatened to kill Yu Xiaogang and sexually assaulted her. Bibi Dong subsequently broke up with Yu Xiaogang to protect him; he blamed her without investigating the circumstances 8 20.

Later broadcasts of Lin Tian’s thoughts describe Yu Xiaogang’s theories as material copied and compiled from ancient texts rather than original research. According to those revelations, his relationship with Bibi Dong gave him access to Spirit Hall’s records, and she helped promote his work 20.

Liu Erlong

The Heavenly Screen also reveals that Yu Xiaogang began a relationship with Liu Erlong only days after separating from Bibi Dong. Upon discovering that she was his second uncle’s daughter, he abandoned her on their wedding night without an explanation, leaving her longing for him for decades 20.

Appearance

• Arrival at Skywater Academy: So unkempt that Lin Tian compares him to a beggar who has not washed for a long time 19.
• After Xiao Wu’s assault: His face is bruised, his joints are loosened, and he is unable to muster strength 22.
• After Bibi Dong’s slaps: Both cheeks become swollen, and blood pours from his mouth 33.

Personality

Yu Xiaogang is proud of his title and intensely concerned with recognition. He assumes that Tang San’s acceptance of him as a teacher proves he can also recruit Lin Tian, and imagines the prestige of becoming the Lord of the Heavenly Dao’s master. Tang San’s flattery reinforces this confidence 9.

His desire for advancement frequently overrides other concerns. Seeing Leng Xi receive rewards makes him forget his recent remorse toward Bibi Dong. After learning that Xiao Wu is a hundred-thousand-year Soul Beast, he regrets not killing her earlier for a Soul Bone that might have broken his cultivation ceiling 9 30.

He also shifts blame and invokes seniority when challenged. After repeatedly demanding greater speed, he blames Tang San for their horse’s death. When Xiao Wu objects, he insists she respect him as an elder and threatens to make Tang San break up with her 16.

Despite denying that he uses Tang San as a test subject, his private thoughts after their reconciliation turn to conducting future experiments more carefully so Tang San will not discover them 22.

Abilities & Skills

Martial Soul Theory

Yu Xiaogang claims extensive theoretical knowledge and uses Tang San’s achievements to defend his credentials 19 20.

• Published work: Claims Ten Core Competencies of Martial Soul as his principal achievement 19.
• Central maxim: Advocates “There are no useless Martial Souls, only useless Soul Masters,” which Lin Tian challenges by pointing to Yu Xiaogang’s own cultivation stagnation 20.
• Disputed originality: The Heavenly Screen describes his work as copied and summarized from ancient texts, with many claims lacking supporting evidence 20.
• Soul Ring guidance: Directed Tang San to attach a hundred-year Mandala Snake Soul Ring to his plant-type Martial Soul. Lin Tian condemns the choice as inferior even to a ten-year Lone Bamboo ring; Tang San nevertheless argues that the ring produced a useful control effect 21 22.

Teaching Methods

His proposed curriculum emphasizes physical fitness, specialization, and cooperation 32.

• Conditioning: Prescribes one hundred laps around the field every day for several months.
• Specialization: Divides students into Power Attack, Agility Attack, Auxiliary, and Control systems.

• Bibi Dong — Former lover whose support helped establish his reputation. After the broadcasts, she questions his sincerity and later beats him while working under the identity “Zhu’er”; he does not recognize her 20 33.
• Liu Erlong — His cousin and former partner, abandoned on their wedding night after he learned their familial relationship 20.
• Xiao Wu — Openly dislikes him and attacks him after learning that he may have harmed Tang San’s development. He later covets the Soul Bone she could leave behind 6 21 22 30.

Story Role / Major Arcs

Journey to Skywater City

After witnessing Leng Xi’s rewards for helping Lin Tian, Yu Xiaogang decides to become an instructor at Skywater Academy and recruit Lin Tian as his disciple. He declares that Lin Tian will take priority over Tang San and imagines eventually reaching level one hundred 5.

His journey begins with the mule swindle. When Tang San and Xiao Wu catch up, he insists on joining them on their horse despite Tang San’s concern about the weight. His repeated demands for speed contribute to the horse dying from exhaustion more than two hundred li from Skywater City. The ensuing argument damages his relationship with Tang San 5 6 16.

Rejection and Public Exposure

At Skywater Academy’s gates, Yu Xiaogang introduces himself to Lin Tian and promises to make him the continent’s strongest person. Lin Tian’s reaction prompts Heavenly Screen broadcasts exposing his alleged plagiarism and past relationships 19 20.

Yu Xiaogang attempts to recover by presenting Tang San’s talent as proof of his teaching. Lin Tian counters that Tang San was already exceptionally gifted, and another broadcast reveals his Twin Martial Souls while accusing Yu Xiaogang of treating him as an experiment. Xiao Wu attacks Yu Xiaogang, but Tang San intervenes and maintains their teacher–disciple relationship 20 21 22.

Admission and Expulsion

Yu Xiaogang accompanies Ning Fengzhi into Skywater Academy and gains admission for his group. By the time the new class gathers, he has been hired as its teaching consultant 27 29 32.

His position collapses when Lin Tian exposes the lack of detail in his training plan. Bibi Dong, whom he knows only as Teacher Zhu’er, slaps him out of the classroom. Qian Renxue then expels him immediately 32 33.

After he invokes Bibi Dong to resist dismissal, Qian Renxue beats him again. At Lin Tian’s suggestion, she agrees to find a Spirit Hall subordinate called Brother Scar to punish him and carries Yu Xiaogang to the city’s Spirit Hall Branch. The provided account does not show that punishment being carried out 33.
