Background

Yu Xiaogang was born into the Blue Lightning Tyrant Dragon Clan, but a mutation in his Martial Soul left him with only half-rank Innate Soul Power and unable to advance beyond Rank 29. Unable to become a powerful Soul Master like his father, he turned to Martial Soul research and promoted his own “Ten Core Competition Theories of Martial Souls.” 57 182

He used a Spirit Hall Elder token to access Spirit Hall research material in Nuoding City and cultivated the public identity of “Grandmaster,” an authority on Martial Soul theory. His standing, however, rested heavily on his clan background and his connection to Bibi Dong rather than his personal strength. 6 57

Appearance

Yu Xiaogang is an ordinary-looking middle-aged man with a rigid, gloomy bearing and a visibly frustrated demeanor. 6

• Wears an unattractive buzz cut. 6
• Has a stiff, old-fashioned expression and manner. 6
• Was left missing several front teeth and bearing a palm print after clashes involving Yu Luomian and Tang Hao. 56 272

Personality

Yu Xiaogang is deeply insecure about his stalled cultivation and craves recognition as a great theorist. He views exceptional disciples, especially Tang San, as the means to prove his theories and erase the stigma attached to his own weakness. 54 55 213

He is outwardly proud and confident in his knowledge, even when events contradict his conclusions. He dismisses reports of Soul Beasts and Spirit Rings beyond his accepted theories, and fails to recognize the evolution of Tang San’s Blue Silver Grass. 181 228 313

In crises, he prioritizes his own safety and status. He fled toward Spirit City when the Blue Lightning Tyrant Dragon Clan faced destruction, leaving Liu Erlong behind, and later sought to bring Tang San into Spirit Hall to improve his own standing there. 239 267 269

Story Role / Major Arcs

Attempt to Recruit Ye Ling

After Ye Ling’s Martial Soul awakening in Nuoding City, Yu Xiaogang mistakes the Ancestral Witch Battle Body for evidence of Twin Martial Souls and tries to take Ye Ling as his disciple. Ye Ling publicly challenges his theory, cultivation level, and claimed accomplishments; Kong Deming then sends Yu Xiaogang flying with a slap. 6

Mentorship of Tang San

Yu Xiaogang takes Tang San as his disciple after recognizing his Innate Full Soul Power, Twin Martial Souls, and Clear Sky Hammer. He sees Tang San’s growth as his opportunity to establish his own name across the continent. 54 55

He later advises Tang San to attach Soul Rings to the Clear Sky Hammer for the All-Continent Advanced Soul Master Tournament, acknowledging that doing so could damage Tang San’s future potential. 182 223

Mending Heaven Chamber of Commerce Incident

Yu Xiaogang attempts to use his Honorary Elder Token to enter Mending Heaven Pavilion’s auction after failing the wealth and status requirements. Ye Ling recognizes him, mocks his earlier attempt to recruit him, and has him detained for impersonating an honorary elder. 184 185

Bibi Dong intervenes and confirms that the token was genuinely issued by Spirit Hall, allowing Yu Xiaogang and Tang San to attend the auction despite the public humiliation. 187 188

Alliance with Spirit Hall

Yu Xiaogang visits Bibi Dong to seek the cultivation method for Twin Martial Souls, revealing Tang San’s identity as Tang Hao’s son and the bearer of Blue Silver Grass and the Clear Sky Hammer. Bibi Dong offers support only if Tang San joins Spirit Hall. 202 203

After the Blue Lightning Tyrant Dragon Clan becomes a target of Mending Heaven Pavilion, Yu Xiaogang flees to Spirit City for Spirit Hall’s protection. He later becomes a Spirit Hall Elder and presses Tang San to join the organization. 239 267

Collapse of the Golden Iron Triangle

Yu Xiaogang’s abandonment of Liu Erlong and lack of concern for her fate leads Flender to confront him. Flender formally ends their friendship and dissolves the Golden Iron Triangle. 269

Tang San also grows tired of Yu Xiaogang’s attempts to control his decisions, rejects his pressure to join Spirit Hall, and begins treating him with open contempt. 272 315

Interest of the Holy Spirit Cult

Zhong Liwu identifies Yu Xiaogang’s greed, jealousy, arrogance, and fear of death as unusually potent negative emotions. The Holy Spirit Cult considers him a suitable vessel for their god’s descent. 315
