Power Progression

Background

Yu Xiaogang comes from the Blue Lightning Tyrant Dragon Clan and has spent decades studying Martial Soul Theory. He published the Ten Core Competencies of Martial Soul and is a longtime friend of Nuoding Academy’s dean 4 10.

At the start of the new term, Tang San accepts Yu Xiaogang as his teacher and acknowledges his theories. Yu Xiaogang promises to make him an outstanding Blue Silver Grass Soul Master and prove that neither of them is useless 1.

Appearance

Yu Xiaogang is a round-faced man with a crew cut and bushy beard. At Nuoding Academy, he wears a gray robe and has a haggard appearance 1.

• Deep eye sockets and dark circles 1.
• Often poses with his hands behind his back and gazes upward while presenting himself as an eminent master 1 2 6.
• Loses an ear to Lin Yan’s Thunderclap Sword in the Soul Hunting Forest 10.

Personality

Yu Xiaogang prizes recognition for his theories and is sensitive to ridicule. He presents himself as the continent’s foremost theorist and considers himself uniquely qualified to teach talented children. Privately, he plans to use Tang San for experiments and Lin Yan to make a name for himself 2.

When his authority is challenged, he can become defensive and hostile. He threatens to discipline Lin Yan after being mocked, but readily apologizes and yields when Lin Yan threatens his life 3 4 10.

Abilities & Skills

Luo Sanpao

Yu Xiaogang’s Martial Soul manifests as a purple pig called Luo Sanpao. He summons it alongside two Yellow Soul Rings 4.

• Luo Sanpao uses fart-based attacks; Yu Xiaogang feeds it white radishes before confronting Lin Yan 4 9.
• Yu Xiaogang exhausts his Soul Power using Luo Sanpao against Gale Wolves while weakened by Mandala Snake poison 9.

Martial Soul Theory

Yu Xiaogang teaches that “there are no trash Martial Souls, only trash Soul Masters” and argues that effort and guidance are essential to a Soul Master’s growth 2 4.

• Martial Soul Mimicry Theory: He maintains that plant Martial Souls can absorb beast-type Soul Rings. He recommends a snake-type ring for Tang San’s Blue Silver Grass to improve its toughness and potentially add poison 6.
• First Soul Ring limit: He claims that a first Soul Ring cannot exceed 423 years. Lin Yan’s successful absorption of a thousand-year first ring challenges that claim 9 10.

• Storage belt — Given to Tang San, who later surrenders it to Lin Yan as compensation after Yu Xiaogang demands that he do so 6 10 11.
• White radishes — Fed to Luo Sanpao before Yu Xiaogang’s attempted confrontation with Lin Yan 4.

Relationships

• Tang San — His first disciple, who initially calls him a second father. Tang San’s admiration deteriorates after Yu Xiaogang’s public humiliation and the confrontation over Lin Yan’s Soul Ring 1 5 11.
• Lin Yan — A gifted student Yu Xiaogang tries to recruit. Lin Yan rejects him, traps him in an illusion, and later wounds him after Yu Xiaogang accuses him of being a Fallen Soul Master 2 4 10.
• Dean of Nuoding Academy — A longtime friend who intervenes to persuade Lin Yan to spare Yu Xiaogang’s life 10.
• Mo Hen — A Nuoding Academy teacher who stands between Yu Xiaogang and Lin Yan when Yu Xiaogang threatens the child 4.

Story Role

Confrontation at Nuoding Academy

After taking Tang San as his disciple, Yu Xiaogang attempts to recruit Lin Yan, another child with Innate Full Soul Power. Lin Yan rejects his offer and mocks his teaching principles. When Tang San withdraws from a proposed duel after experiencing an illusion, Yu Xiaogang summons Luo Sanpao to discipline Lin Yan himself 2 3 4.

Lin Yan traps Yu Xiaogang in Tsukuyomi. Believing that the continent’s Soul Masters have weakened while he remains at level 29, Yu Xiaogang declares himself the “Fart God.” Still under the illusion, he soils Mo Hen, Tang San and the gathered crowd; the spectacle ends when he exhausts himself 4 5.

Soul Hunting Forest

Several days later, Yu Xiaogang takes Tang San to hunt a Soul Ring. He initially considers a Ten-Year Solitary Bamboo before continuing the search and recommending a snake-type ring. After Tang San obtains a Mandala Snake ring, the pair encounter Gale Wolves; Yu Xiaogang is poisoned and runs out of Soul Power. Tang San briefly considers abandoning him but attempts to save him after a wolf bites him 6 9.

Lin Yan and the dean arrive, and Lin Yan defeats the wolves. When Tang San questions how Lin Yan obtained a thousand-year first ring despite Yu Xiaogang’s stated limit, Yu Xiaogang accuses Lin Yan of using an evil technique and threatens to report him to Spirit Hall. Lin Yan cuts off one of his ears, then agrees to spare him after the dean intervenes. Yu Xiaogang apologizes and forces Tang San to surrender his storage belt as compensation, leaving Tang San questioning his teacher’s theories 9 10 11.
