Background

Yu Xiaogang is a martial soul theorist whose interest in rare and mutated spirits leads him to permit Lin Mo to accompany Tang San on an early Soul Hunting Forest expedition. He is immediately intrigued by Lin Mo's unrecorded mutated spirit and seeks a detailed account of Lin Mo's spar with Xiao Wu. 5 6

He serves as Tang San's teacher, providing both martial soul instruction and emotional guidance. When Tang San becomes discouraged by Lin Mo's apparent superiority, Yu Xiaogang reminds him of the potential of his twin martial souls and urges him to cultivate without comparing himself to others. 6

Yu Xiaogang's own martial soul, Luo Sanpao, is a malignant mutation. The mutation left him with only half-level innate soul power and a cultivation bottleneck at level 29, leading him to devote himself to martial soul theory. 7 27

After Lin Mo proposes that Luo Sanpao might evolve through nourishment from high-level dragon-type soul beasts, Yu Xiaogang reconsiders the limitations he had accepted for years. He leaves Notting Academy to seek Flender's help, then obtains flesh from a ten-thousand-year Thunder Flood Dragon for Luo Sanpao. 28 30 31

Appearance

Yu Xiaogang has a pale, melancholy appearance and dresses in muted, practical clothing. 6

• White hair beneath a gray knit cap.
• Dark stubble and a pale complexion.
• Thick gray scarf, light-gray loose top, and long black sleeveless vest.
• A persistent melancholy between his brows. 6

Personality

Yu Xiaogang is intensely curious about unusual martial souls and remains willing to investigate phenomena outside established records. His fascination with Lin Mo's spirit motivates him to approve the early forest trip and repeatedly examine Lin Mo's abilities. 5 6 9

Despite his long-standing self-doubt over Luo Sanpao, he is a patient and attentive mentor. He reassures Tang San when the latter loses confidence, aims to secure better spirit rings for his disciples, and adjusts his theoretical conclusions when reality demands it. 6 7 26 50

He is also capable of humility. Lin Mo's advice on Blue Silver Grass cultivation and Luo Sanpao's evolution causes Yu Xiaogang to reconsider his own theories and pursue a new path rather than remain trapped by his prior failures. 12 28 29
