Background / History

Yu Xiaogang initially sought Tang San as a disciple after noticing his potential as a twin martial soul user. He expected Tang Wulin's guidance to fail and intended to later offer Tang San “hope,” thereby gaining his respect and proving his own theories 3.

Tang San rejected Yu Xiaogang's attempts at recruitment, choosing Tang Wulin as his sole teacher. Yu Xiaogang promoted animal soul rings for Blue Silver Grass and could not substantiate his promises; the confrontation escalated when he used his spirit skill and was badly injured by Tang San and Tang Wulin 8 9.

After failing to recruit Tang San, Yu Xiaogang repeatedly tried to make Xiao Wu his disciple. He claimed recognition from Spirit Hall, a close relationship with Pope Bibi Dong, and involvement in selecting Bibi Dong's soul rings, promising Xiao Wu strength comparable to the Pope's. Xiao Wu rejected and beat him 28 39.

He later recruited Flender and Zhao Wuji to assassinate Tang Wulin, hoping to remove Tang Wulin and claim Xiao Wu as a disciple. The attempt failed; Tang San and Xiao Wu punished Yu Xiaogang by castrating and publicly hanging him at Notting Academy's gates 39 43 44 45.

Yu Xiaogang remained obsessed with revenge and continued searching for a disciple who could validate his theories. His father, Yu Yuanzhen, eventually returned him to the Blue Lightning Tyrant Dragon Clan and forbade him from leaving after learning of the assassination attempt 67 68.

Within the clan, Yu Xiaogang accepted Yu Tianheng as his disciple. He planned to train Tianheng using Pope Bibi Dong's spirit-ring configuration, defeat Tang San, and eventually leave the clan with Tianheng after six years 70. He later reunited with Liu Erlong; their contact triggered an unexpected two-person Martial Soul Fusion Skill that engulfed much of the clan in foul, scalding mist. Yu Yuanzhen ordered both imprisoned 87 88.

After Yu Yuanzhen's martial soul evolved, Yu Xiaogang persuaded Yu Tianheng and Liu Erlong to flee the clan with him. He framed their departure around revenge against Tang Wulin and Tang San, as well as Liu Erlong's desire to reclaim her Fire Dragon bloodline 128. The clan discovered their escape three days later; Yu Yuanzhen publicly expelled Yu Xiaogang and Liu Erlong and disowned Yu Tianheng when the latter chose not to return 129.

Yu Xiaogang subsequently arrived at Shrek Academy with Liu Erlong and Yu Tianheng, adopting “Grandmaster” as his preferred name. He exploited his former connection to Flender and falsely portrayed Tang Wulin as having murdered Flender and Zhao Wuji without cause, encouraging Shrek's teachers to preserve and cultivate students capable of eventually seeking revenge 138 139. After proposing that Ma Hongjun balance his Evil Fire Phoenix through an ice- or water-attribute soul ring, Shrek Academy's senior teachers accepted his guidance and appointed him dean 140 141.

Personality

Yu Xiaogang is arrogant, resentful, and intensely preoccupied with having his theories recognized. He considers talented disciples a means to prove himself, repeatedly pursuing Tang San, Xiao Wu, and later Yu Tianheng for that purpose 3 28 67 70.

His failures and humiliation deepen his vindictiveness. Even after castration and confinement, he focuses on revenge against Tang Wulin, Tang San, and Xiao Wu, while viewing Yu Tianheng as his prospective route to restored status and personal recovery 45 67 87.

Yu Xiaogang is also manipulative and self-aggrandizing. After leaving the clan, he used Flender's death and Shrek Academy's lack of information to turn its teachers against Tang Wulin, presenting himself as a benevolent authority while concealing his own role in the failed assassination plot 139. He treats Shrek's students as a new opportunity to demonstrate that his theories can create Titled Douluo and restore his reputation 140 141.
