Background / History

Yu Xiaogang was once the young master of the Blue Lightning Family, but a mutated Martial Soul left him unable to progress beyond level 30. His fall from the family’s expectations subjected him to ridicule, an experience that remains a major source of insecurity. 1 210

At Notting Academy, he works as a consultant and develops a reputation for spirit-master theory despite his poor combat ability. He accepts Tang San as his sole direct disciple and oversees Tang San’s first spirit-ring hunt. 6 15 210

During the Mandala Snake expedition, Yu Xiaogang is poisoned and falls unconscious for three days. Tang San kills the snake, obtains his first soul ring, and cares for Yu Xiaogang until he recovers; Yu Xiaogang privately regards the incident as proof of his own inadequacy. 15 18

Tang Hao later reveals that Tang San is his son and threatens Yu Xiaogang to solve Tang San’s unstable soul skill. The threat leaves Yu Xiaogang terrified and increasingly desperate to preserve his theories and position as Tang San’s teacher. 20 21 22

He later joins Shrek Academy as the team’s leader and conducts “Grandmaster-level” intensive training, including weighted endurance work and sparring exercises. 80 85

Appearance

Yu Xiaogang ordinarily presents himself with a stiff, composed, and scholarly demeanor, though repeated system-induced incidents drastically alter his public image.

• His mutated Martial Soul, Luo Sanpao, is described as pig-like and visibly weak. 6
• Following Aquamid’s effects, his chest enlarges abnormally; observers note that it becomes larger than Zhu Zhuqing’s. 91 93
• After an assault while drunk, he returns with dust-covered clothing and a stiff, awkward gait. 94
• Later groin injuries leave him unable to walk normally and at risk of severe lasting damage. 212 245 247

Personality

Yu Xiaogang cultivates an image of calm detachment and intellectual authority. Zhang Tianyu considers this persona deceptive, believing that people unfamiliar with Yu Xiaogang could mistake him for a hidden expert. 1

He is deeply sensitive to mockery, particularly when it recalls the scorn he received after his Martial Soul mutation. Even while humiliated, he often attempts to preserve his dignity through a cold, indifferent façade. 1 7 18

His confidence in his theories is central to his self-worth. When Tang San’s Blue Silver Binding loses control, Yu Xiaogang becomes distressed that his spirit-ring theories may be wrong. 19 20

As Tang San’s teacher, he can be attentive and proud of his disciple’s growth, but their relationship steadily deteriorates into mutual resentment. Yu Xiaogang increasingly favors Zhang Tianyu’s exceptional potential, while privately regarding Tang San as disrespectful and inferior. 192 210 239 242

Story Role / Major Arcs

Notting Academy humiliation

Zhang Tianyu’s first mission after returning to the past targets Yu Xiaogang. A note reading “I am a huge idiot” is placed on Yu Xiaogang’s back, causing passersby to laugh at him until he discovers the source. 1

Yu Xiaogang is subsequently beaten by Director Su and publicly afflicted with uncontrollable, deafening farts caused by Zhang Tianyu’s Mountain-Opening Cannon. 5 6 7

Tang San’s spirit-ring hunt

Yu Xiaogang accompanies Tang San to obtain his first spirit ring. He is poisoned by the Mandala Snake, while Tang San defeats it and later nurses him back to health. 15 18

After Tang San’s Blue Silver Binding begins uncontrollably targeting Yu Xiaogang, Tang Hao intervenes violently and orders Yu Xiaogang to fix the issue. 18 19 20 21

Aquamid transformation

Zhang Tianyu secretly applies Aquamid to Yu Xiaogang. Its delayed effects enlarge Yu Xiaogang’s chest, while Consciousness Confusion prevents him from recognizing the change. 77 90 91 92

The transformation draws concern and confusion from the Shrek group, pushes Yu Xiaogang into drinking alone, and contributes to further humiliation and physical harm. 93 94 96

Unexplained episodes at the Soul Fighting Arena

Yu Xiaogang begins displaying erratic behavior, including dancing, shouting, stripping, and appearing naked in public. He repeatedly denies or cannot remember these incidents afterward. 148 150 151 157 158

The group comes to suspect that he is suffering from the same type of unconscious behavior previously seen in Tang San. 151

Family reunion and public revelation

Yu Tianheng approaches Yu Xiaogang and urges him to return to the Blue Lightning Family. Yu Xiaogang refuses, identifies himself as Shrek’s leader, and expresses pride in Tang San’s potential. 210

During the Golden Iron Triangle’s reunion, Yu Xiaogang publicly announces that he is a woman and reveals Aquamid-enhanced chest growth, shocking Liu Erlong, Flender, and the Shrek group. 229

Breakdown of the master-disciple relationship

Yu Xiaogang and Tang San’s resentment becomes overtly mutual. Yu Xiaogang believes Tang San resents his attention toward Zhang Tianyu, while Tang San believes Yu Xiaogang only accepted him for his Innate Full Soul Power. 239 242

A Bad Luck Sticker causes Yu Xiaogang to slip into a painful split, be thrown down by Tang San, and suffer escalating groin injuries. Both privately contemplate revenge against the other. 244 245 247
