Background / History

Yu Xiaogang was present at the Sacred Dragon Sect's spirit-awakening ceremony, where Tuoba Xuan awakened a yellow piglet martial soul and was believed to possess only innate level-three soul power. Seeing a similarity to his own Luo Sanpao, Yu attempted to make Tuoba Xuan his student and use him to test his martial-soul theories. Tuoba rejected him and exposed details of Yu's past; Yu retaliated by publicly calling him trash whose soul power would never advance. 20

By the time Shrek Academy considered joining the Heaven Dou Royal Academy, Yu led the academy's radical faction alongside Tang San and three other Shrek Devils. The opposing conservative faction consisted of Flender, Zhao Wuji, other senior teachers, Ma Hongjun, Oscar, and Dai Mubai. 17

Yu and Tang San directed Shrek's tactics during its soul-fighting match against the Imperial Fighting Team. Tang San's loss of focus caused the team's favorable position to collapse, prompting Ma Hongjun and Dai Mubai to question the strategy and creating deeper divisions within Shrek. 17

At Heaven Dou Royal Academy, Yu pleaded for Shrek's group to withdraw under Dugu Bo's pressure, but still issued a threat before leaving. Tang San's outburst then led Tuoba Xuan to confront Yu directly. 19

Tuoba publicly revealed Yu's past treatment of him and challenged both Yu and Tang San. Yu identified himself as a level-29 Great Spirit Master, then suffered a severe emotional reaction when Tuoba revealed his level-40 soul power and Mountain Dragon King martial soul. Although he agreed to fight alongside Tang San, the match was postponed after he spat blood and became physically unwell. 20 21

Personality

Yu is highly protective of his position as Tang San's teacher and reacts strongly when his authority or theories are challenged. He attempted to rebut Tuoba Xuan by invoking Tuoba's former stagnation at level three, then demanded Tang San defeat Tuoba to validate his own theories. 20

He is also shown as politically ambitious in Shrek's internal dispute, supporting the move to a higher-level academy despite opposition from the academy's older teachers and several students. 17
