Abilities
Soul Master Theory
Yu Xiaogang is chiefly known as a theorist rather than a combatant. He considers theory the foundation of a Soul Master's development and regards practical combat as an extension of theoretical knowledge. He placed great faith in his teachings and hoped Tang San would become proof of his theories. 49
He lectured on the Ten Core Competencies of Martial Soul, bodily-potential development, and the matching of Soul Skills in combat. His training program at Shrek Academy included weighted cross-country running, sparring, physical conditioning, and team soul battles. 88 90 91
Under his revised combat-oriented curriculum, Tang San became the tactical core of the Shrek Seven Devils, while the team's coordination and reputation in Suotuo City's Great Soul Arena improved considerably. 91
Limitations
Yu Xiaogang possesses only level 29 Soul Power and has little demonstrated practical combat capability. During Tang San's acquisition of his second Soul Ring, the academy headmaster handled the hunt while Yu Xiaogang could only observe. 49
Li Hanche's unprecedented soul-ring configuration and combat ability directly challenged Yu Xiaogang's accepted soul-ring age limits, causing him to question the theories on which he had built his reputation. 95 96
Personality
Yu Xiaogang is proud of his theoretical learning and deeply desires recognition as the Grandmaster. Early in Tang San's training, he believed that guiding a Twin Martial Soul genius to the pinnacle of the Soul Master world would redeem his long-standing reputation. 49
His confidence is closely tied to his theories, status, and Tang San's success. Challenges to any of these repeatedly leave him shaken, defensive, or emotionally unstable. 95 118 150
Despite his insecurity, he remains committed to training Tang San and initially sought to establish authority over Shrek Academy's students through formal lectures and strict training. 88 90
Relationships
| Character | Relationship |
|---|---|
| Tang San | Yu Xiaogang's disciple and the person he viewed as the ultimate proof of his theories. Tang San initially defended him fiercely, but their relationship deteriorated after Yu Xiaogang's repeated humiliations and public scandals. 49 96 147 170 188 |
| Flender | Long-time friend and supporter. Flender brought Yu Xiaogang to Shrek Academy, defended the value of his training methods, and repeatedly helped him after Li Hanche's attacks. 88 90 97 |
| Liu Erlong | Former lover. Yu Xiaogang's past relationship with Liu Erlong remained a source of emotional turmoil, and Li Hanche's intervention created further strain between them. 95 142 147 |
| Bibi Dong | Formerly close enough for Yu Xiaogang to address her as “Dong'er.” Their relationship became hostile; when he later requested the cultivation method for Twin Martial Souls, she coldly ordered him to address her as the Pope. 170 201 |
| Li Hanche | Primary antagonist. Li Hanche despises Yu Xiaogang's theories, background, and treatment of Tang San, repeatedly humiliating, assaulting, and undermining him. 87 96 119 143 |
| Xiao Wu | Initially Tang San's companion, Xiao Wu gradually developed intense resentment toward Yu Xiaogang, blaming him for Tang San's suffering and denouncing his worthiness as a teacher. 136 170 |
| Blue Lightning Tyrant Dragon Clan | Yu Xiaogang is connected to the clan but was described by Li Hanche as having been abandoned by it. He suffered a complete emotional breakdown after learning of the clan's destruction. 97 247 |
History
| Event | Details |
|---|---|
| Teaching Tang San at Notting Academy | Yu Xiaogang instructed Tang San at Notting Junior Soul Master Academy and took pride in Tang San's Innate Full Soul Power, Twin Martial Souls, diligence, and potential. 49 |
| Robbery on the road to Suotuo City | Li Hanche used family tokens to order a Soul Douluo to beat and rob Yu Xiaogang. Yu Xiaogang was found badly injured and stripped of his belongings by a roadside patrol. 87 88 |
| Appointment at Shrek Academy | Flender introduced Yu Xiaogang as Shrek Academy's Grandmaster and assigned him responsibility for the students' training. Several students immediately questioned his authority upon learning that he was only level 29. 88 89 |
| Conflict with Li Hanche at the Great Soul Arena | After witnessing Li Hanche's soul rings and overwhelming physical strength, Yu Xiaogang publicly demanded an explanation. Li Hanche mocked his theories, assaulted him, and trampled his dignity before the crowd. 95 96 97 |
| Exposure of Tang San's Twin Martial Souls | During the confrontation at Heaven Dou Royal Academy, Li Hanche publicly raised the possibility that Tang San possessed Twin Martial Souls. Yu Xiaogang inadvertently confirmed the secret while attempting to defend his own theory. 117 118 |
| Expulsion from Heaven Dou Royal Academy | Yu Xiaogang, Tang San, and their supporters were subjected to the pressure of Dugu Bo and Sea Dragon Douluo before being forced from Heaven Dou Royal Academy. Tang San dragged the badly weakened Yu Xiaogang away from the academy. 119 120 121 |
| Deterioration at Shrek Academy | Yu Xiaogang's standing at Shrek collapsed as Tang San, Xiao Wu, and the other students increasingly rejected his instruction. Xiao Wu publicly condemned him, while Tang San eventually regarded the Twin Martial Soul cultivation method as Yu Xiaogang's only remaining value. 170 188 |
| Public disgrace in Spirit City | Li Hanche and Yue Guan installed a Spirit City gate sign declaring that “Yu Xiaogang and pigs are not allowed inside,” accompanied by a parody poster identifying him as a former honorary elder of Spirit Hall and Shrek Academy's disgrace. 187 |
| Request to Bibi Dong | Yu Xiaogang sought Bibi Dong's Twin Martial Soul cultivation method in Pope's Palace. After she refused him, he swore that he would one day destroy Spirit Hall. 201 |
| Destruction of the Blue Lightning Tyrant Dragon Clan | When Spirit Hall exterminated the Blue Lightning Tyrant Dragon Clan and killed Yu Yuanzhen, Yu Xiaogang broke down alongside Yu Tianheng and Liu Erlong. 246 247 |
Reputation
Yu Xiaogang was once publicly regarded as the Grandmaster and held the position of honorary elder within Spirit Hall. However, Li Hanche repeatedly alleged that his theoretical work relied on Spirit Hall archives and that his status was supported by the Blue Lightning Tyrant Dragon Clan and Bibi Dong. 87 119
These accusations eventually became a continent-wide scandal. Rumors concerning his past relationship with Bibi Dong, his former honorary elder status, and the origins of his theories left him ostracized at Shrek Academy and ridiculed throughout the Soul Master world. 170 187 201
