Background / History

Yu Xiaogang is the second son of Blue Lightning Tyrant Dragon Sect Master Yu Yuanzhen. His mutated martial soul, Luo Sanpao, left him unable to break through level 30 despite years of effort, becoming a source of disappointment for both himself and his family 1.

When his nephew Yu Tianjue awakened a similarly pig-like mutated martial soul with only innate level one soul power, Yu Xiaogang felt a sense of shared misery. He sincerely offered to take Tianjue away from the sect, hoping his own experience with Luo Sanpao could prevent Tianjue from suffering the same scorn and stagnation 1 2. Tianjue rejected the proposal, openly questioning Xiaogang's ability to help while he remained below level 30; Xiaogang left the confrontation in anger 2.

After Tianjue's martial soul evolved into the ice-attributed fledgling dragon Xiao Hei, Yu Xiaogang returned late at night with a final offer to leave the sect and inherit his research. The evolution shook his confidence in his own knowledge of martial souls, but it also drove him to seek Tianjue as a subject for researching secondary mutation and evolution 7 8.

Yu Xiaogang proposed an Ice Silkworm as a possible first soul-ring target, then repeatedly pressed Tianjue to leave with him so he could uncover the secret behind Xiao Hei's evolution. He framed the research as a benefit to the clan and the spirit master world, but Yu Yuanzhen refused to let him take away a newly revealed innate-full-soul-power genius 8 9 10. Yu Xiaogang subsequently left the Blue Lightning Tyrant Dragon Sect in desolation 11.

Second Life Simulation

During Yu Tianjue's second life simulation, Yu Xiaogang arrives at Shrek Academy as Tang San's teacher. He is stunned by Tianjue's yellow, purple, purple, black soul-ring configuration and the unfamiliar Asura Sword martial soul, both of which contradict his established theories 20.

His knowledge also proves incomplete when Xiao Wu explains the phenomenon of soul shock from ten-thousand-year soul rings—a subject Xiaogang does not know despite his reputation as the Grandmaster 20.

Appearance

Yu Xiaogang is typically described as stiff-faced and rigid in bearing. When he visits Tianjue before leaving the sect, he appears exhausted, bloodshot-eyed, and coldly detached 7.

• Often maintains an expressionless or rigid face 1 20
• Appears stubborn and isolated during the sect's martial soul awakening ceremony 1
• His desperation over Tianjue's evolved martial soul leaves him visibly bitter and dejected 9 10

Personality

Yu Xiaogang is deeply sensitive about his failed cultivation and Luo Sanpao's reputation. His initial attempt to take Tianjue away is motivated by genuine concern: he does not want his nephew to endure the ridicule and mistreatment that he experienced 2.

However, his desire to validate his research becomes obsessive after Xiao Hei evolves. He becomes fixated on discovering the cause of Tianjue's secondary mutation, pressures Tianjue to leave the clan, and reacts bitterly when his theories and personal limitations are exposed 8 9 10.

He is proud of his theoretical knowledge and struggles to accept evidence that contradicts it. Tianjue's exceptional soul rings and martial soul evolution leave him shocked, doubtful, and forced to question his understanding of martial souls 8 20.

Abilities & Skills

Luo Sanpao

Yu Xiaogang possesses Luo Sanpao, a mutated externalized beast martial soul. Unlike typical beast martial souls that possess their users, Luo Sanpao exists independently outside its master's body 1 15.

• Considered a mutated and weak martial soul by the Blue Lightning Tyrant Dragon Sect 1
• Possesses a trace of Light Sacred Dragon bloodline 2
• Its existence as an externalized beast martial soul is rare within the sect 9
• Yu Xiaogang remains unable to break through level 30 soul power during the early narrative 1 2

Martial Soul Research

Yu Xiaogang has spent years studying martial souls and seeks to pass his research on to Yu Tianjue 7 10.

• Promotes the belief that a soul master's effort, rather than their martial soul alone, determines their potential 2
• Attempts to explain Xiao Hei as a beneficial secondary mutation triggered after Tianjue's awakening 8
• Suggests ice-attributed soul beasts, including the Ice Silkworm, for Xiao Hei's soul-ring selection 8
• His father considers much of his research to be inherited clan and sect knowledge supplemented by Xiaogang's own insights 10
• His theories do not account for Tianjue's abnormal soul-ring configuration or the phenomenon of soul shock 20

Relationships

• Yu Yuanzhen — Father and Sect Master of the Blue Lightning Tyrant Dragon Sect. Yu Yuanzhen worries about Xiaogang's future but rejects his request to take Tianjue away for research 9 10.
• Yu Tianjue — Nephew. Xiaogang initially tries to protect him from repeating his own fate, then becomes determined to study Tianjue's martial soul evolution 2 7 9.
• Yu Tianheng — Nephew and Tianjue's twin brother. Tianheng supports Xiaogang's initial proposal that Tianjue should try cultivating under his guidance 2.
• Tang San — Student during Yu Tianjue's second life simulation. Xiaogang serves as Tang San's instructor at Shrek Academy 20.
• Flender — Future member of the Golden Iron Triangle after Xiaogang leaves the sect 11.
• Liu Erlong — Future Golden Iron Triangle companion; Xiaogang later enters a controversial relationship with her 11.
