Background / History

Yu Xiaogang is Yu Xiaolong's older half-brother. Both were burdened by Luo Sanpao martial souls and were derided as the Blue Lightning Tyrant Dragon Clan's “Crouching Dragon and Fledgling Phoenix.” Yu Xiaogang remained at level 29 for roughly two decades after his martial soul awakened. 1 3

He developed the Ten Core Competencies of Martial Souls and asked Yu Xiaolong to leave the sect with him to research them. He promised to share half of his future achievements and honors, but internally intended to make Xiaolong a servant and assistant. Xiaolong rejected him, attacked the validity of his theory, and called him a “trash spirit master,” ending their partnership. 1

After accepting Tang San as his disciple, Yu Xiaogang placed his hopes in Tang San's talent and viewed him as proof that his theories could succeed. When Dugu Bo attacked Tang San over Dugu Yan's injury, Yu Xiaogang joined Flender and Liu Erlong in resisting the Titled Douluo so Tang San could escape. 8

Learning that Yu Xiaolong had also taken a gifted disciple, Yu Xiaogang sought him out in the Star Dou Great Forest. He attempted to pressure Xiaolong into leaving the area and encouraged Tang San to challenge him, believing Xiaolong was still only level 28. 9 10

Yu Xiaolong's Arrow of Death severely injured Tang San, provoking Yu Xiaogang into swearing vengeance. Their subsequent encounter at Heaven Dou Royal Academy intensified the brothers' feud: Yu Xiaogang demanded an apology for Tang San, while Xiaolong mocked his level 29 cultivation and his theoretical authority. 11 12

Yu Xiaogang continued to place his faith in the Shrek Team and the Continental Advanced Soul Master Elite Competition, intending to use their results to prove his theories and restore his reputation. When Yu Xiaolong later challenged Shrek Academy, Yu Xiaogang accepted to defend the academy's honor, but his students were defeated by Xiaolong's disciples. 12 26 28
