Background

Yu Xiaogang presented himself at Nuoding Academy as the foremost authority on martial-soul theory. He claimed that Tang San’s innate full Soul Power proved the existence of a second, powerful martial soul, dismissing Blue Silver Grass as inherently weak. Yin Chuan refuted his reasoning and struck him after he insulted Tang San’s martial soul. 8 9

Yu Xiaogang persisted in insisting that Tang San must be concealing another martial soul, treating the boy’s denial as dishonesty rather than reconsidering his own theory. When Yin Chuan revealed that Tang San’s martial soul had mutated into the same Blue Silver Tyrant Spear as his own, Yu Xiaogang was left unable to answer and fainted after Yin Chuan mocked Luo Sanpao’s mutation. 9 10

He repeatedly sought to take Tang San—and later Yin Chuan—as disciples. His interest was driven by their exceptional talent and the prestige he believed their achievements could bring him. After learning that Yin Chuan was a twelve-year-old Spirit Ancestor, Yu Xiaogang considered taking both uncle and nephew as disciples a path to recognition. 11 12

When Yin Chuan left Nuoding Academy, Yu Xiaogang became Tang San’s homeroom teacher. He attempted to establish authority over Tang San, but their hostility escalated when Tang San sent him into a wall with Overlord Disarming Armor. 16 17

After locating Yin Chuan and Tang San at Shrek Academy, Yu Xiaogang falsely implied that Tang San’s rapid growth was the result of his own instruction. He later joined Shrek as Dean of Academic Affairs, where his criticism of Yin Chuan’s teaching led to a student “interview” that ended with Tang San severely injuring him. 37 38 39

Yu Xiaogang subsequently joined Flender and Liu Erlong in the Golden Iron Triangle’s Martial Soul Fusion Skill against Yin Chuan and Tang San. After their defeat, Yin Chuan crippled Yu Xiaogang’s Soul Power while preserving his martial soul. 49 50 51 52

After becoming powerless, Yu Xiaogang remained dependent on Flender and Liu Erlong. He opposed Shrek Academy’s proposed defection to Yin Chuan and suggested lowering the academy’s admission standards to increase tuition income, a proposal rejected by Flender and Zhao Wuji. 81 82

Yin Chuan later presented Yu Xiaogang and Liu Erlong with recommendation letters to Spirit Hall, ostensibly recognizing their talents while removing them from Blue Tyrant Academy. Yu Xiaogang accepted the arrangement because he viewed Spirit Hall—and his past connection with Bibi Dong—as an opportunity to regain influence. He also swore upon Luo Sanpao to repay Yin Chuan’s one-million-Gold-Soul-Coin loan and not act against his creditor. 106 107

Appearance

Yu Xiaogang is described as having a distinctive flat-top haircut and a self-consciously imposing manner. 8 11

• Often adopts a solemn, authoritative tone when invoking his theoretical reputation. 8 9
• His appearance and speech become visibly disheveled after repeated injuries from Tang San. 39 48
• After losing his Soul Power, he is unable to resist further public humiliations and can only weep when Liu Erlong is degraded before others. 88
• The Howling Celestial Dog repeatedly humiliates him and Liu Erlong, including soaking them with urine before prominent witnesses. 88 106

Personality

Yu Xiaogang is arrogant and deeply invested in being recognized as an unparalleled martial-soul theorist. He invokes his “Master” title and Blue Lightning Tyrant Dragon Sect background to establish authority, while reacting poorly when Yin Chuan or Tang San dismisses him. 9 12

His ambition centers on attaching himself to talented disciples. He regards Tang San and Yin Chuan less as individuals to support than as extraordinary prospects who could elevate his own name and status. 11 12 16

Despite his bravado, he is fearful when confronted by superior force. He avoids fighting Tang San when offered the choice, calls for Flender’s help under attack, and loses control in terror after the Golden Iron Triangle’s defeat. 38 39 51

After becoming powerless, Yu Xiaogang remains unwilling to withdraw from the Spirit Master world. He relies on Flender and Liu Erlong for survival, yet continues to devise theoretical or financial solutions while avoiding responsibility for carrying them out himself. 81 82

Yu Xiaogang is opportunistic beneath his cowardice. He immediately recognizes Yin Chuan’s recommendation to Spirit Hall as a possible route to restore his status through Bibi Dong, even while suspecting that Yin Chuan intends to use him against Spirit Hall. 106 107

Abilities & Skills

Martial Soul: Luo Sanpao

Yu Xiaogang possesses the martial soul Luo Sanpao.

• He could summon Luo Sanpao before his Soul Power was crippled. 49
• Luo Sanpao could use Earth-Shattering Luo Sanpao against Tang San, but it was unable to stop Tang San’s assault. 39
• Following the loss of his Soul Power, Luo Sanpao falls dormant and cannot be effectively used. 52 53
• Yu Xiaogang’s oath to Yin Chuan is sworn upon Luo Sanpao; breaking it would cause his martial soul to shatter. 107

Martial Soul Theory

Yu Xiaogang claims authority through his “Ten Core Competencies of Martial Spirits” theory and his reputation as the Master. 8 9

• He identified Tang San’s innate full Soul Power as unusual and theorized that Tang San possessed another martial soul. 8
• His conclusions about the incompatibility of martial souls of differing quality were challenged by Yin Chuan. 9
• He continued to insist that Tang San had another martial soul even after Tang San denied it, interpreting the denial as a failure of discipline rather than a challenge to his theory. 9
• His theoretical knowledge does not compensate for his lack of combat strength. 38 39
• During Shrek Academy’s financial crisis, he proposed admitting less-qualified students for tuition income, which Flender rejected as contrary to Shrek’s elite-only principle. 82

Golden Iron Triangle

Yu Xiaogang can participate with Flender and Liu Erlong in the Golden Iron Triangle Martial Soul Fusion Skill. 49

• The fusion manifests the Golden Sacred Dragon and its golden protective light. 49 50
• Yin Chuan and Tang San’s fusion skill shatters its defenses and defeats the trio. 50 51
• The backlash leaves Yu Xiaogang unable to resist Yin Chuan afterward. 51
• Yu Xiaogang bears less of the fusion backlash than Flender and Liu Erlong because the two Soul Saints absorb most of the burden. 51

Relationships

• Yin Chuan — Former Nuoding Academy colleague and persistent target of Yu Xiaogang’s recruitment efforts; Yin Chuan repeatedly humiliates him and eventually cripples his Soul Power. Yin Chuan later sends him toward Spirit Hall under a restrictive debt oath, intending to make use of Yu Xiaogang as a destabilizing influence. 11 12 37 52 106 107
• Tang San — Former student whom Yu Xiaogang tries to claim as a disciple; their relationship is openly hostile, with Tang San repeatedly attacking him for disrespecting Yin Chuan. 16 17 39
• Flender — Fellow member of the Golden Iron Triangle and Shrek Academy associate; Flender supports Yu Xiaogang, though he eventually fails to protect him from Yin Chuan and Tang San. After Yu Xiaogang is crippled, Flender continues to shelter him but grows frustrated with his proposals for Shrek’s survival. 36 37 49 53 81 82
• Liu Erlong — Fellow Golden Iron Triangle member and devoted lover; she seeks revenge after Tang San injures him, then shares his defeat at Yin Chuan’s hands. Despite becoming powerless herself, she remains willing to sacrifice for Yu Xiaogang’s security. 48 49 52 83
• Bibi Dong — Yu Xiaogang’s former lover and the Pope of Spirit Hall. He sees his recommendation to Spirit Hall as an opportunity to use their past connection to recover his standing. 106
• Luo Sanpao — His martial soul; rendered dormant after Yu Xiaogang loses all Soul Power. 49 53

Story Role / Major Arcs

Nuoding Academy

Yu Xiaogang first approaches Tang San over his unusual martial soul and attempts to establish himself as Tang San’s necessary guide. Yin Chuan’s intervention turns this into a rivalry, as Yu Xiaogang’s claims are refuted and his attempts to recruit either uncle or nephew fail. 8 9 10

He becomes Tang San’s homeroom teacher after Yin Chuan’s departure, but antagonizes Tang San rather than earning his respect. Tang San’s retaliation leaves Yu Xiaogang injured and disgraced at Nuoding Academy. 16 17

Shrek Academy

Yu Xiaogang arrives at Shrek hoping to reconnect with Yin Chuan and Tang San, regretting his earlier failure to claim them as disciples. He overstates his role in Tang San’s development to Flender and joins the academy as Dean of Academic Affairs. 36 37 38

His challenge to Yin Chuan’s teaching ability provokes Tang San, who badly injures him during the proposed student evaluation. 38 39

Conflict with Yin Chuan

Yu Xiaogang joins Flender and Liu Erlong against Yin Chuan and Tang San through the Golden Iron Triangle fusion skill. Their defeat leads to the loss of Blue Tyrant Academy and Yu Xiaogang’s complete loss of Soul Power. 49 50 51 52

Shrek’s Decline and Spirit Hall Departure

After his crippling, Yu Xiaogang opposes Flender’s attempt to abandon Shrek Academy and seek refuge with Yin Chuan. His proposal to lower admissions standards for revenue alienates Flender and Zhao Wuji, exposing the divide between his pragmatism and Shrek’s founding ideals. 81 82

Yin Chuan later humiliates Yu Xiaogang and Liu Erlong before offering them recommendation letters to Spirit Hall. Yu Xiaogang accepts, hoping that his prior relationship with Bibi Dong will let him recover his influence, but he must first bind himself with a one-million-Gold-Soul-Coin debt oath that forbids default or rebellion against Yin Chuan. 106 107

Trivia

• Yu Xiaogang reached level 30 before age fifty, a feat he cites as evidence of his authority. 8
• Before Yin Chuan crippled him, he possessed level 29 Soul Power. 52
• He initially believed Yin Chuan was in his twenties, despite having previously seen records identifying him as a twelve-year-old Spirit Ancestor. 37
• Yu Xiaogang’s attempt to maintain Shrek Academy through lower admissions standards is rejected because it would violate Flender’s principle of cultivating only elite students. 82
• His debt oath to Yin Chuan is backed by Luo Sanpao; violating it would shatter his already dormant martial soul. 107
