History
At Notting Academy, Yu Xiaogang sought to teach Tang San and Tang Wu, hoping the brothers would help prove his martial-soul theories. He recommended poison-attribute rings for their Blue Silver Grass, but they rejected the advice. The brothers later accepted his help identifying soul beasts without taking him as their master; Tang San again disregarded his advice when choosing a plant-type first ring 7 8.
Flender introduced Yu Xiaogang as Shrek Academy's training guide. His running regimen and demand for obedience brought him into conflict with Tang Wu, splitting the students into rival training groups. Gangzi subsequently gave his nephew Yu Tianheng detailed information on the Shrek team's abilities and Tang Wu's habits before their match against the Heaven Dou Royal Academy team 32 34 39.
His feud with Tang Wu escalated through repeated confrontations. After Tang Wu's Toothpick Fish attack left him severely injured, Gangzi sought help from his father, Yu Yuanzhen. He later leaked information about Tang Wu to Qian Renxue. Fearing retaliation, he fled to Star Luo City and abandoned Liu Erlong 52 57 61 85 139.
Tang Wu found him in Star Luo City and knocked him unconscious. Gangzi awoke in a pig's body, having exchanged bodies with his martial soul, Luo Sanpao; Luo Sanpao then asserted control. Yue Guan and Gui Mei took him to Martial Soul City, where Bibi Dong eventually severed ties with him and drove him away. While wandering, Gangzi died after losing control of the gas produced by his pig body 139 140 145 197.
Appearance
Before the body swap, Gangzi was a weathered-faced, middle-aged man with short hair. Afterward, he appeared as a purple-skinned pig creature 32 39 197.
- His short hair prompted Oslo to call him a “flat-top” 39.
- During his years in hiding, his hair grew messy and his clothes became patched 139.
Personality
Gangzi takes pride in his title and theories, insisting on his authority even when students question his methods. He seeks recognition for his research and reacts angrily to criticism 7 32 34 52.
His grudge against Tang Wu leads him to share Shrek's confidential information with an opposing team and later leak information to Qian Renxue. When confronted directly, however, he flees or appeals to others for protection 39 85 139 145.
Abilities & Skills
Martial-Soul Theory and Soul-Beast Knowledge

Luo Sanpao
- His martial soul, Luo Sanpao, can be summoned separately and produces gas that Tang Wu exploits in combat and for flight 10 11 62.
