Appearance

Yu Xiaogang is a middle-aged man with a crew cut and a rigid, stiff expression. He generally presents himself with an aloof, scholarly bearing. 24 30

• Sallow complexion and stiff facial features. 30
• Often stands with his hands behind his back while analyzing situations. 24 30
• Became unkempt and hollow-eyed after his humiliation by Yu Tianyu. 27

Personality

Grandmaster is intensely devoted to martial soul theory and considers his Ten Core Competencies authoritative. He confidently analyzes opponents and offers tactical instruction, even when his assumptions are challenged by circumstances. 24 25

His fixation on proving his theories makes him persistent and defensive. After Yu Tianyu publicly dismantles his claims and exposes Luo Sanpao's origins, Grandmaster continues insisting that he is right and directs his resentment toward Yu Tianyu. 25 29

He is deeply invested in Tang San's future. He trains Tang San, urges him to seek victory by any means in battle, develops the Seven-in-One Fusion Skill as a comeback strategy, and seeks Bibi Dong's guidance to solve Tang San's Twin Martial Souls conflict. 27 40 41

Abilities & Skills

Martial Soul Theory

Grandmaster is known for the Ten Core Competencies of martial souls and frequently assesses spirit-master teams, martial souls, spirit rings, and combat methods. 25 27

• Believed the Mad Battle Team was nearly unbeatable at Soto City's level without a team of Spirit Elders or a powerful control-system spirit master. 24
• Claimed that Yu Tianyu's ringless Dragon Roar might be a self-created spirit skill, a spirit bone skill, or an unknown mutation direction. 24 25
• Asserted that the second spirit ring's limit was 764 years, a claim contradicted when Yu Tianyu revealed a thousand-year second ring. 20
• Sought to study Yu Tianyu's techniques to expand his own theories on ringless casting. 25

Tactical Instruction

Grandmaster directs Shrek Academy's combat preparation and formulates strategies centered on Tang San.

• Suggested using Blue Silver Grass as cover for Tang San's hidden weapons and Zhuge Divine Crossbow. 27
• Recommended Tang San's Eight Spider Lances as a poison-based finishing weapon. 27
• Taught the Seven-in-One Fusion Skill, a formation that channels six teammates' spirit power into Tang San and can temporarily raise his explosive output to Spirit Saint level. 40
• Advocated continued participation in the Continental Advanced Spirit Master Academy Elite Tournament despite the danger posed by Spirit Hall. 36

Luo Sanpao

His martial soul is a failed mutation of the Blue Lightning Tyrant Dragon. 25

• Luo Sanpao instinctively submitted to Yu Tianyu's superior Blue Lightning Tyrant Dragon bloodline. 25
• Its collapse under Yu Tianyu's dragon aura caused Grandmaster's own knees to buckle due to their linked senses. 25
• Yu Tianyu derides Luo Sanpao as capable only of farting. 25

History

Grandmaster accompanies Shrek Academy to Soto City and learns that the newly registered World Burial Team has intercepted the Mad Battle Team. He initially judges the Mad Battle Team too formidable to lose under ordinary circumstances, then observes World Burial's overwhelming victory and becomes preoccupied with Yu Tianyu's ringless Dragon Roar. 24

After the match, he approaches the World Burial Team to offer tactical advice and request access to Yu Tianyu's self-created skill. Yu Tianyu rejects his criticism, reveals himself as Yu Xiaogang's nephew and Yu Yuanzhen's son, and exposes Luo Sanpao as a failed Blue Lightning Tyrant Dragon mutation. Grandmaster is forced to kneel when his martial soul submits to Yu Tianyu's bloodline. 25

Following this humiliation, Grandmaster focuses on helping Tang San defeat Yu Tianyu. He advocates hidden weapons, the Zhuge Divine Crossbow, and the Eight Spider Lances, framing Tang San's duel as a test of both his student's honor and the validity of the Ten Core Competencies. 27

He later brings Shrek Academy to Heaven Dou Royal Academy to use its Mimicry Cultivation Environment. When confronted by Yu Tianyu, he cannot intervene against him despite Liu Erlong's expectation that he would stand beside her. 30 35

At the Grand Finals in Spirit City, Grandmaster seeks Bibi Dong because she is the only known person he believes can solve Tang San's Twin Martial Souls conflict. His appeal fails, further damaging his pride and leaving him responsible for Tang San's worsening situation. 41

Relationships

• Tang San — Student and the central focus of Grandmaster's training, tactical plans, and efforts to solve the Twin Martial Souls backlash. 25 27 40 41
• Yu Tianyu — Nephew and adversary; Yu Tianyu publicly humiliates him, disputes his theories, and exposes Luo Sanpao's failed mutation. 25
• Flender — Shrek Academy's dean and Grandmaster's longtime associate; Flender warns him against confronting World Burial but accompanies him to their lounge. 25
• Bibi Dong — Has a past relationship with Grandmaster; he seeks her help for Tang San in Spirit City, but she rejects and humiliates him. 41
• Liu Erlong — A woman who had waited for him for twenty years; Grandmaster does not oppose Yu Tianyu when she is threatened. 35
• Dugu Bo — Holds Grandmaster in contempt as someone with little talent who enjoys preaching. 27
