Background / History

Yu Xiaogang was born into the Blue Lightning Tyrant Dragon Clan as Yu Yuanzhen’s son. His father regarded him as a disgrace after he awakened Luo Sanpao, a pig-like martial soul associated with farting, and Yu Xiaogang was expelled from the clan. Yu Yuanzhen nonetheless later hoped his son’s claimed theories might allow him to change his fate. 2 31

At Shrek Academy, Yu Xiaogang trained the Shrek Seven Devils and held particular confidence in Tang San. He believed Tang San’s future godhood would vindicate him before both the clan and the wider continent, allowing him to claim that he had “cultivated a god.” 1 5

When Martial Soul Hall pursued Tang San, Yu Xiaogang intervened despite being vastly weaker than Chrysanthemum Douluo and Ghost Douluo. Chrysanthemum Douluo slapped him away, shattering his front teeth; Tang Hao’s arrival ultimately protected Tang San. Yu Xiaogang then left with Tang Hao and Tang San after Shrek Academy disbanded, insisting that Tang San still needed his guidance. 13 15

Personality

Yu Xiaogang is deeply preoccupied with proving his worth. Years of being branded a failure by the Blue Lightning Tyrant Dragon Clan drove him to seek recognition through theory, teaching, and Tang San’s anticipated future achievements. 2 5

He is highly self-assured in his analyses and reacts poorly when Tang San questions them. His certainty repeatedly leads him to make disastrous arena bets, yet he habitually rationalizes his mistakes rather than accepting responsibility. 17 32 62

His protectiveness toward Tang San is intertwined with self-interest: Yu Xiaogang expects Tang San to take him to the God Realm after becoming a god. Once Tang San loses the Clear Sky Hammer, Yu Xiaogang immediately doubts his value and harshly blames him instead of offering comfort. 6 37 50

Abilities & Skills

Martial Soul Theory

Yu Xiaogang styles himself as the continent’s foremost master of theory and frequently uses his knowledge of spirit masters, martial souls, and combat history to instruct Tang San. 14 17

• Identified Tang Hao as the Clear Sky Douluo and recounted his rise to fame. 14
• Developed betting theories based on choosing the apparently weaker side, claiming this would guarantee victory. 31
• His arena predictions repeatedly fail, costing both himself and Tang San spirit power and other stakes. 25 37 41

Luo Sanpao

Luo Sanpao was Yu Xiaogang’s martial soul before he wagered and lost it in the arena system. It was considered weak by both Yu Xiaogang and his clan. 2 37

• Its flatulence could become stronger after eating additional radishes. 32
• Yu Xiaogang wagered it on Xuan Zi’s victory over Golden Crocodile Douluo in hopes of obtaining a second Luo Sanpao and becoming a Twin Martial Soul possessor. 32
• Xuan Zi lost, and Luo Sanpao was forfeited. 37

Relationships

• Tang San — Disciple. Yu Xiaogang sees Tang San’s future godhood as the proof of his own teaching ability and hopes Tang San will bring him to the God Realm; Tang San increasingly distrusts and resents his guidance. 5 6 37 62
• Yu Yuanzhen — Father and Blue Lightning Tyrant Dragon Clan Sect Master. Yu Yuanzhen considered Yu Xiaogang a failure but later hoped he would validate his theories and become useful to the clan. 2 31
• Tang Hao — Tang San’s father and a figure Yu Xiaogang admires. Yu Xiaogang accompanied Tang Hao and Tang San after Shrek’s disbandment. 14 15
• Bibi Dong — Yu Xiaogang holds intense admiration and longing for her, repeatedly asserting that she cannot lose in battle. 38 40 41
• Liu Erlong — She continues to wait for Yu Xiaogang and sees Bibi Dong’s aging as removing a romantic rival. 43
• Chrysanthemum Douluo and Ghost Douluo — They openly despise Yu Xiaogang; Chrysanthemum Douluo slapped him aside when he tried to shield Tang San. 13

Story Role / Major Arcs

Shrek Academy and Tang San’s Protector

Yu Xiaogang gathers and trains the Shrek Seven Devils, expressing complete confidence that his students will not lose to peers. Once Tang San is exposed as Martial Soul Hall’s future enemy, Yu Xiaogang vows to protect him at any cost. 1 5

Arena Gambling Downfall

Seeking a shortcut past rank 30, Yu Xiaogang wagers all rank-29 spirit power on Zhongli Wu. Qian Xunji’s victory strips him to zero spirit power. 17 25

Still convinced of his own theories, Yu Xiaogang later wagers Luo Sanpao on Xuan Zi. Xuan Zi loses to Golden Crocodile Douluo, and Yu Xiaogang loses his final martial soul. 32 37

Loss of Tang San’s Trust

Yu Xiaogang’s repeated misjudgments cause Tang San to reject his betting advice. Tang San eventually uses Yu Xiaogang’s support for one competitor as a reason to bet on the other. 38 41 60

After Huo Yuhao defeats Tang San and the Clear Sky Hammer is stripped away, Yu Xiaogang abandons his confidence in Tang San’s potential and blames his injured disciple for ruining his expectations. 50
