Background / History

Yu Xiaogang first meets Tang San at Notting Academy. Tang San kneels and asks to recognize him as a father; Yu Xiaogang accepts him as his godson and begins guiding his cultivation. He also repeatedly attempts to recruit Ye Xian as a disciple, but is refused each time. 5 9 16

After Tang San reveals his altered Clear Sky Hammer, Yu Xiaogang recognizes its aura and warns him not to reveal it or attach Soul Rings to it without permission. He subsequently takes Tang San and Ye Xian into the Soul Hunting Forest to seek their first Soul Rings. 9

During the expedition, Yu Xiaogang uses Luo Sanpao to drive off Netherworld Wolves, but is severely injured and poisoned in an encounter with a Mandala Snake. Tang San saves his life, leaving Yu Xiaogang permanently physically diminished. Yu Xiaogang later guides Tang San to absorb a ten-year Ghost-Face Bolète Soul Ring. 11 15 16

Yu Xiaogang gives Tang San a cultivation guide based on his research, remains at Notting Academy during the holiday, and is entrusted by Tang Hao to care for Tang San before Tang Hao leaves. 18 20

Five years later, Yu Xiaogang goes to Shrek Academy looking for Tang San. He joins the academy as an adviser rather than a regular instructor, offering consultation on Martial Souls and cultivation. The students learn that his Soul Power is only level 29 and that Luo Sanpao is regarded as weak. 33 36 47

He continues to advocate for Tang San despite Tang San's poor Soul Duel performances, persuading Flander to allow him into team battles. Yu Xiaogang later spends heavily on spirit medicines and personally trains Tang San, helping him reach level 30. 59 86 112

In Sunset Forest, Yu Xiaogang accompanies Tang San against a Man-Faced Demon Spider. He remains behind the front line to provide tactical support, but is critically injured when a second spider ambushes him. His recovery requires hospitalization and later transplant surgery. 114 116 119 127

To fund Tang San's treatment and his own plans, Yu Xiaogang accepts humiliating work, borrows from the Billion Zero Workshop, and returns to the Blue Lightning Tyrant Dragon Clan to obtain 300,000 Gold Soul Coins. His failure to repay the black-market loan results in wanted notices and the release of private photographs. 74 82 135 142 143

After becoming separated from the Shrek group, Yu Xiaogang and Tang San travel to Heaven Dou City in severe hardship. They are eventually taken in by Liu Erlong at Blue Tyrant Academy, where their past connection as members of the Golden Iron Triangle is revealed. 136 150

Personality

Yu Xiaogang is proud of his theoretical knowledge and frequently presents himself with deliberate confidence. He seeks recognition as the “Great Master,” especially from gifted youths such as Ye Xian, and reacts poorly when his expertise or status is dismissed. 9 11 16 33

His confidence is undermined by his limited combat strength, poor physical condition, and repeated setbacks. He can be vain, stingy, resentful of charity, and prone to blaming others when Tang San is treated unfavorably. 66 98 122 123

Despite these flaws, Yu Xiaogang is deeply attached to Tang San. He persistently supports Tang San's advancement, provides instruction and resources, secures funds for his treatment, and makes major personal sacrifices for his godson's future. 18 70 74 87 112
