Biodata

Power Progression

Appearance

• Hair: Introduced with a crew cut, again described as a buzz cut during the Star Dou Great Forest encounter; a later passage describes his head as bald 4 26 33.
• Snake-attack injuries: Returns from the Soul Hunting Forest with a swollen face and severely swollen backside 12.
• Injuries from Tang San: Suffers facial swelling and loses teeth after being punched. The swelling still affects his speech when they meet again in Precious Sword City 29 33.

Personality

Yu Xiaogang is deeply concerned with his reputation as “Grandmaster.” Unable to advance beyond level twenty-nine, he turns to theory to prove that there are no useless Martial Souls, only useless Soul Masters. He regards an exceptional disciple as the means to vindicate his work and escape being treated as a laughingstock 4 5.

His recruitment efforts combine persistence, entitlement, and manipulation. He treats Tang San’s refusal as an insult, assumes that displaying Spirit Hall credentials will secure obedience, and exploits Xiao Wu’s attachment to Tang San to persuade her to become his disciple. He privately considers his less-talented student a useful subject for testing his theories 4 5 13.

Public humiliation leaves him resentful and vindictive. He avoids confronting Qian Renxue directly after learning of her Spirit Hall connections, but works against her through Xiao Wu. His fixation on Tang San later escalates into demands for an apology and orders for Shrek students to beat him to death 13 29 30.

Abilities & Skills

Martial Soul Theory

Yu Xiaogang bases his teaching authority on his Ten Core Competencies of Martial Soul 5.

• Research objective: Seeks to demonstrate that a Soul Master can overcome a seemingly useless Martial Soul through proper cultivation 5.
• Recognition of talent: Infers Tang San’s Twin Martial Souls from his admission certificate and immediately identifies him as an ideal disciple 4.
• Soul Ring recommendations: Selects a ten-year Solitary Bamboo, also called Lone Bamboo, for his staff-wielding disciple. He claims its attributes can help the long staff Martial Soul evolve; the supplied passages do not establish that this works 11.
• Criticism: Qian Renxue argues that his lack of experience beyond level twenty-nine undermines his higher-level cultivation advice. Xiao Wu later states that his instruction has taught her nothing useful 5 27.

Soul Beast Identification

• Recognizes a Mandala Snake and identifies it as a hundred-year Soul Beast, prompting him to order a retreat 11.
• Identifies a Light Giant Dragon and advises the Shrek group that it has a gentle nature and should not be provoked 28.

Combat Limitations

• Remains restricted to level twenty-nine 5.
• Escapes a snake attack with substantial injuries alongside his disciple 12.
• Is incapacitated by a single restrained punch from Tang San, without Tang San using a Soul Skill 29.

Equipment / Items

• Spirit Hall third-class writ — Presented as evidence of Spirit Hall’s recognition of his authority. Qian Renxue identifies it as a third-class writ rather than an Elder Token. Bibi Dong gave it to him because of their past relationship, not his theoretical achievements 5 6.
• Forest-entry token — Uses a token to enter the Soul Hunting Forest with his newly accepted disciple 9.

History

Rejected Apprenticeships at Nuoding

After discovering Tang San’s Twin Martial Souls through his admission certificate, Yu Xiaogang resolves to make him his disciple. Tang San has already refused once before their first depicted confrontation; when Yu Xiaogang presses him again, Tang San repeats that he has no intention of taking a master. Yu Xiaogang then approaches Qian Renxue, mistakenly assuming that her attendance at a junior academy means she has only recently begun cultivation 4.

Qian Renxue rejects him and publicly exposes his half-level Innate Soul Power and level-twenty-nine ceiling. When he invokes Spirit Hall’s recognition, she also exposes the true nature and origin of his writ. The confrontation destroys his credibility among the watching students, and he leaves vowing to find a disciple who will surpass both her and Tang San 5 6.

Qian Renxue’s hostility also reflects her memories of her previous life: she regards Yu Xiaogang’s guidance as responsible for Tang San’s ineffective first three Soul Rings and believes that he and Shrek Academy delayed Tang San’s cultivation 4 9.

New Disciples and the Soul Hunting Forest

Yu Xiaogang accepts a freshman with level-five Innate Soul Power and a long staff Martial Soul. In the Soul Hunting Forest, he directs the boy to absorb a ten-year bamboo Soul Ring, arguing that it can promote Martial Soul evolution. A Mandala Snake interrupts the attempt, and both teacher and student return to the academy badly swollen from the attack 9 11 12.

He next targets Xiao Wu because of her Innate Full Soul Power. After she initially refuses, he tells her that Qian Renxue is recruiting Tang San for Spirit Hall. He promises that his instruction will let Xiao Wu surpass Tang San, causing Tang San to recognize his mistake and return. Xiao Wu accepts him as her teacher 12 13.

Joining Shrek Academy

Following the damage to his reputation at Nuoding, Yu Xiaogang seeks out Flender and becomes a teacher at Shrek Academy. By the time he encounters Tang San again, he has repeatedly discussed Tang San with the Shrek students and remains convinced that even Twin Martial Souls cannot succeed without proper guidance 26 29.

Star Dou Great Forest Confrontations

During a Shrek Soul Ring expedition, Yu Xiaogang sees Tang San apparently travelling alone and assumes that Spirit Hall has failed to support him. He mocks Tang San’s prospects and orders Xiao Wu to leave his side. Xiao Wu instead denounces his teaching and offers to stop being his disciple. Ning Rongrong and Zhu Zhuqing also reject his attempt to turn the disagreement into a conflict with the entire academy 26 27.

At their next encounter, Yu Xiaogang offers Tang San a place on the Shrek Academy Team in exchange for an apology. Tang San answers with a punch that throws him into a tree and knocks out teeth. Tang San deliberately spares his life, partly to avoid provoking Bibi Dong and partly because he wants to discredit him more thoroughly 29.

Yu Xiaogang orders the students to retaliate and later urges Ma Hongjun to beat Tang San to death, claiming that he will handle the consequences. After Ma Hongjun is also defeated, the two leave at the rear of the group with swollen faces 29 30 31.

Precious Sword City

Still injured, Yu Xiaogang encounters Tang San and Qian Renxue again in Precious Sword City while accompanied by Ma Hongjun, Zhao Wuji, and other Shrek members. He points Tang San out resentfully, and the encounter develops into another confrontation as Dai Mubai challenges him 33.

Relationships

• Tang San — Repeatedly rejected prospective disciple and the focus of his resentment. Yu Xiaogang initially sees Tang San’s Twin Martial Souls as the key to proving his theories; Tang San ultimately beats him after another demand for submission 4 29.
• Qian Renxue — Rejected prospective disciple who publicly exposes his cultivation limits and misleading use of Spirit Hall credentials. She actively works to keep Tang San from becoming his student 4 5 6.
• Bibi Dong — Shares a past relationship with him and gives him the Spirit Hall writ. He later considers approaching her to retaliate against Qian Renxue through his connections; no such visit is shown 6 13.
• Xiao Wu — Becomes his disciple after he exploits her desire to reunite with Tang San. She later calls his teaching useless and openly challenges his authority 13 27.
• Lin Tian / Liu Tian — Staff-wielding disciple whose name appears as Lin Tian in the earlier forest passages and Liu Tian after the snake attack. Yu Xiaogang views him as a means of testing his theories 9 11 12 13.
• Flender — Connection through whom he joins Shrek Academy after his humiliation at Nuoding 29.
• Dai Mubai — Defuses the argument after Xiao Wu’s rebuke and later prompts Ma Hongjun to intervene on Yu Xiaogang’s behalf because he is a Shrek teacher 27 29.
• Ning Rongrong and Zhu Zhuqing — Reject his attempt to involve them in his dispute with Tang San. Zhu Zhuqing nevertheless helps him to his feet after he is punched 27 30.
