Background

Yu Xiaogang was born into the Blue Lightning Tyrant Dragon Clan as the Clan Master's son. Because his martial soul mutated and did not inherit the clan's legacy, he was rejected by his family. Unable to pursue great strength, he devoted himself to researching Soul Master theory in hopes of earning recognition through knowledge. 186 192

While traveling, Yu Xiaogang met Flender and later Liu Erlong. The three discovered that their coordination could produce a powerful Martial Soul Fusion Skill and became known as the Golden Iron Triangle. Yu Xiaogang and Flender both fell in love with Liu Erlong, but Liu Erlong chose Yu Xiaogang because of his perseverance and theoretical knowledge. 186 191

At Notting Academy, Yu Xiaogang accepted Tang San as his disciple after recognizing his Twin Martial Souls. He also attempted to recruit Huo Feng, whose Innate Full Soul Power and attack-type martial soul made him an attractive candidate for Yu's research; Huo Feng refused. 5 13

During a Soul Beast hunt for Tang San, Yu Xiaogang was poisoned by a Mandala Snake. Tang San amputated Yu Xiaogang's right arm to prevent the venom from spreading. 16 17

Appearance

Yu Xiaogang is initially depicted with a stiff expression and an empty right sleeve after losing his arm. Later injuries leave him reliant on a wheelchair, and he eventually uses a prosthetic arm. 58 170 192

• Lost his right arm following Mandala Snake venom poisoning. 16 17
• Later used a prosthetic arm, which exposed his identity when it was torn off. 192
• Became permanently disabled and used a wheelchair after the Man Faced Demon Spider incident. 163 170
• Returned from the Blue Lightning Tyrant Dragon Clan wearing expensive clothing and carrying a Black Card. 153 154

Personality

Yu Xiaogang is intensely proud of his status as a martial soul theorist and is highly sensitive to perceived disrespect. He repeatedly expects preferential treatment at Shrek Academy, clashes with Zhao Wuji over accommodation, and attempts to preserve his dignity even after being humiliated. 65 66

He is deeply invested in Tang San's future. Yu pays Tang San's debts, secures him entry into Shrek Academy after his failed examination, searches for methods to develop Tang San's Twin Martial Souls, and treats Tang San as the son he will never have. 58 59 299

His concern for Tang San is often mixed with excessive expectations and vanity. Yu frequently boasts about Tang San's potential, tries to obtain a place for him on Shrek's team, and struggles to accept Tang San's repeated defeats. 52 98 99 170

Abilities & Skills

Martial Soul Theory

Yu Xiaogang's principal strength is his theoretical knowledge of martial souls, Soul Beasts, soul rings, and fusion skills.

• Was appointed at Shrek Academy to provide private martial soul theory advice, rather than regular teaching. 68
• Identified the difference between Canghui Academy's Seven-in-One Fusion Skill and a true Seven-in-One Martial Soul Fusion Skill. 242
• Provided Tang San with information and tactical advice against the Man Faced Demon Spider. 158 159
• Guided Tang San to Soul Ancestor level and helped prepare him to lead the Blue Tyrant Team. 195

Luo Sanpao

Yu Xiaogang's martial soul is Luo Sanpao. Its combat utility is limited, but he used it to create an opening against a Man Faced Demon Spider.

• Activated Luo Sanpao's two soul-ring abilities to distract the spider while Tang San summoned the Clear Sky Hammer. 159
• His low Soul Power sharply limits his capacity to intervene directly in dangerous battles. 158

Influence and Credentials

Despite his low cultivation, Yu Xiaogang possesses connections and credentials that allow him to influence academy and Spirit Hall affairs.

• Used his connection with Flender to help Tang San enter Shrek Academy despite failing the entrance examination. 59 63
• Held a Pope Order given to him by Tang San's father; Platinum Bishop Salas recognized the token and withdrew the Temple Knights. 252 254
• Was made an elder of Blue Tyrant Academy and later acted as its vice-dean. 252 254

Equipment / Items

• Pope Order — A high-ranking Spirit Hall token given to Yu Xiaogang by Tang San's father. 252 254
• Prosthetic arm — Used after the loss of his right arm; its removal revealed him as the wanted suspect in the clan-theft case. 192
• Black Card — Used to meet the Heaven Dou Grand Auction House's asset-verification requirement. 154

Relationships

• Tang San — Disciple. Yu Xiaogang accepts him at Notting Academy, repeatedly protects and supports him, and later calls him the son he never had. 5 58 299
• Flender — Former friend and fellow member of the Golden Iron Triangle. Their relationship deteriorates after Yu repeatedly exploits Flender's resources and resents his treatment at Shrek Academy. 102 168
• Liu Erlong — Former Golden Iron Triangle companion and Yu Xiaogang's longtime love. She entrusts Blue Tyrant Academy to him and pays back the stolen clan money to protect him. 186 191 192
• Bibi Dong — A former romantic partner. Yu visits her after twenty years to seek the method for overcoming the limitations of Twin Martial Souls, but she refuses. 299 300
• Huo Feng — A former recruitment target who refused Yu Xiaogang's offer of discipleship. Yu later regrets failing to secure him as a disciple. 5 13 173 182
• Zhao Wuji — A hostile colleague at Shrek Academy. Zhao openly rejects Yu's demands and later taunts him after Huo Feng's Soul Arena victory. 66 101
• Blue Lightning Tyrant Dragon Clan — Yu's birth clan. He returned to its treasury and took 250,000 Gold Soul Coins to support Tang San, later facing exposure and repayment demands. 153 192

Story Role / Major Arcs

Notting Academy and Tang San's Apprenticeship

Yu Xiaogang becomes Tang San's teacher and recognizes his Twin Martial Souls. He tries unsuccessfully to recruit Huo Feng as a second disciple, viewing both children as promising subjects for his theories. 5 13

Shrek Academy

After Tang San fails Shrek Academy's entrance examination and falls into debt at a blacksmith shop, Yu Xiaogang finds him, repays his debt, and arranges for him to enter Shrek through Flender's connections. Yu's arrogant demands quickly create friction with Zhao Wuji, the teachers, and the students. 47 58 59 65 68

Yu attempts to have Tang San inserted into Shrek's Soul Arena lineup by finding faults in the existing team. Huo Feng's decisive victory over the Berserk Team ruins this plan and worsens Yu's relationship with Flender and Zhao Wuji. 98 99 101

Permanent Injuries and Break with Flender

During the Soul Beast hunt, Yu Xiaogang is attacked by a second Man Faced Demon Spider and suffers catastrophic injuries. Flender later admits that he ordered Tang San to save Yu by removing his manhood, leaving Yu unable to accept the result and permanently disabled. 160 163 168 170

Yu's resentment toward Flender ultimately ends their friendship. Though he initially refuses Flender's food out of pride, he later accepts the academy meals to maintain his strength for training Tang San. 168 169

Blue Tyrant Academy

Yu Xiaogang and Tang San arrive at Blue Tyrant Academy seeking work and are initially hired as janitors. Their reunion with Liu Erlong changes their circumstances: she gives Yu authority over the academy and supports him when the Blue Lightning Tyrant Dragon Clan accuses him of stealing from its treasury. 186 191 192

He focuses on Tang San's development, helping him reach level 40, obtain a 5,000-year Crypt Demon Spider soul ring, and become captain of the Blue Tyrant Team. 195

Continental Advanced Soul Master Academy Elite Tournament

Yu Xiaogang coaches and advocates for Tang San's Blue Tyrant Team throughout the tournament. He boasts about Tang San's battlefield control after Blue Tyrant Academy's victory over Zuan Academy, but also remains prepared to stop matches when Tang San faces severe danger. 202 203 230 241

When Tang San is blinded after the Canghui Academy match, Yu works with Liu Erlong to protect him and the Blue Tyrant students from investigation. He later uses the Pope Order to force Salas to reconsider arresting the academy's members. 245 247 251 252

Visit to Papal Hall

Seeking a solution for Tang San's Twin Martial Souls, Yu Xiaogang travels to Spirit City and meets Pope Bibi Dong after twenty years apart. He asks her to reveal how she overcame the obstacle herself, offering to ensure Tang San never opposes Spirit Hall; Bibi Dong refuses. 297 299
