History

Attempt to Recruit Xu Qing

While collecting his Spirit Hall subsidy in Nuoding City, Yu Xiaogang hears about Xu Qing, a child with a supposedly useless card Martial Soul but innate full Soul Power. Convinced that this combination indicates twin Martial Souls, he visits Xu Qing’s home, hoping to recruit a disciple whose achievements will vindicate his theories 4.

Yu Xiaogang mistakes Xin for a powerless woman afflicted by a harmful Martial Soul mutation and treats her as Xu Qing’s slave. He asks Xu Qing to dismiss her before their discussion, then insists that the boy possesses twin Martial Souls despite his explicit denial. When rejected, he promises to make Xu Qing a Titled Douluo and warns that absorbing Soul Rings without his guidance could prove fatal 4.

After Xu Qing mocks his cultivation and mutated Martial Soul, Yu Xiaogang summons Luo Sanpao to punish him. Xin knocks him unconscious before his attack is released. Xu Qing kicks him and orders Xin’s puppet to throw him into a cesspit, but pauses to search for books on Soul Beasts 4.

Captivity and Escape

Before the punishment is carried out, Brother Scar and two companions approach. Calling Yu Xiaogang “Rose,” they offer 5,000 Gold Soul Coins for him. Xu Qing accepts and hands over both Yu Xiaogang and Luo Sanpao 5.

Yu Xiaogang suffers sexual abuse during his captivity and swears revenge against Xu Qing and the Rose Boy Band. He eventually persuades his captors to release him temporarily, giving them Twenty-Four Moonlit Bridges as a supposed token of affection 6 7 9.

During this temporary freedom, he accepts Tang San as his disciple. Tang San’s innate full Soul Power, Blue Silver Grass, and second Martial Soul—the Clear Sky Hammer—renew his hopes of proving his theories. Fearing recapture, Yu Xiaogang packs his belongings and leaves Nuoding City with Tang San, seeking protection from Flender in Suotuo City 7.

Tang San’s First Soul Ring

After taking refuge with Flender, Yu Xiaogang accompanies him and Tang San to the outskirts of the Star Dou Great Forest. He identifies a ten-year Lone Bamboo as a possible source of toughness for Blue Silver Grass, but keeps it only as a backup. His preferred choice is a Mandala Snake, whose toughness and paralytic venom he believes will grant Tang San both entanglement and poison attributes 8.

Flender captures a four-hundred-year Mandala Snake, which Tang San kills and begins absorbing. Yu Xiaogang watches eagerly, believing a successful absorption will validate his Martial Soul Mimicry Theory 9.

While Tang San is occupied, a ten-thousand-year Cave Demon Spider drags Yu Xiaogang underground. Flender pursues it and pulls him from its mouth, but Yu Xiaogang has already been poisoned in the genital region 9 10.

Emergency Treatment and Recovery

Flender suppresses the spreading poison with Soul Power until Tang San finishes absorbing his ring. Tang San then seals Yu Xiaogang’s meridians while Flender attempts to extract the venom orally. When this fails, Tang San concludes that removing the poisoned tissue is the only way to prevent the venom from reaching his heart meridians 10.

Tang San amputates Yu Xiaogang’s penis, stops the bleeding, and bandages the wound. Flender carries him away from the forest. At Shrek Academy, Shao Xin’s healing sugar beans heal his injuries, and Tang San confirms that rest should be sufficient following detoxification 10 16.

Appearance

• Build and features: Thin, with a crew cut, full beard, fair skin, and a prominent nose 4 5 8.
• After captivity: Deathly pale, with sunken eyes, an unsteady gait, a hoarse voice, and a lingering unpleasant smell. His complexion later improves, though he still walks awkwardly 7 8.
• Distinguishing mark: A black, hollow heart-shaped tattoo on his abdomen, noticed by Tang San during his recovery; its origin is not explained 16.

Personality

Yu Xiaogang is intensely concerned with recognition as a theorist. He sees both Xu Qing and Tang San as potential proof of his work, repeatedly imagining that a successful disciple will silence those who mock him. His recruitment attempts rely heavily on his title of Grandmaster and promises of eventual Titled Douluo cultivation 4 7 9.

He is dismissive toward people he judges weak. Believing Xin has no Soul Power, he orders her around and assumes she is a slave. He also refuses to reconsider his twin-Martial-Soul diagnosis when Xu Qing or Xiao Wu contradicts him. When Xu Qing openly ridicules him, he responds by attempting physical punishment 4 16.

Despite his pride, Yu Xiaogang can bargain when his safety is at stake. He persuades Brother Scar’s group to grant him temporary freedom, sacrifices a valuable storage tool, and seeks Flender’s protection rather than risk being taken captive again 7 9.

Abilities & Skills

Luo Sanpao

Luo Sanpao is Yu Xiaogang’s external beast Martial Soul, manifested separately as a purple, pig-like creature 4 5.

• Yu Xiaogang summons it during his confrontation with Xu Qing and calls out “Earth-Shattering Luo Sanpao!” Xu Qing identifies the impending attack as a foul-smelling fart 4.
• Luo Sanpao loses consciousness when Yu Xiaogang is knocked unconscious 4.
• According to Xu Qing, experiences inflicted on the external Martial Soul feed back to its master 5.
• Yu Xiaogang puts on a mask before attempting the attack 4.

Martial Soul Theory

Yu Xiaogang publishes the Ten Core Theories and presents himself as an authority on Martial Soul cultivation 4.

• Innate Soul Power: He argues that innate Soul Power is directly proportional to Martial Soul quality. He consequently treats innate full Soul Power paired with an apparently weak Martial Soul as evidence of twin Martial Souls 4 16.
• Twin Martial Souls: He correctly recognizes Tang San’s situation, which Tang San confirms by revealing his Clear Sky Hammer. The same reasoning produces rejected diagnoses for Xu Qing and Xiao Wu 4 7 16.
• Martial Soul Mimicry Theory: He expects Tang San’s absorption of a Mandala Snake ring to demonstrate his theory’s validity 9.
• Criticism: Xu Qing argues that entanglement is an inherent plant function that Tang San could develop through practice, making a dedicated Soul Ring unnecessary. This is Xu Qing’s assessment, not a conclusion Yu Xiaogang accepts 8.

Soul Beast Knowledge

Yu Xiaogang can identify Soul Beasts and recommend traits for a disciple’s development 8 9.

• Recognizes Lone Bamboo’s toughness and recommends it as a backup ring source 8.
• Selects the Mandala Snake for its durable body and nerve-paralyzing venom 8.
• Possesses reference books that Xu Qing and Xin later use to improve their own Soul Beast knowledge 9.

Equipment & Items

• Twenty-Four Moonlit Bridges: A storage Soul Tool surrendered to Brother Scar’s group in exchange for temporary release 9.
• Replacement storage Soul Tool: Given to Tang San as an apprenticeship gift; Tang San carries his dagger in it 9.
• Soul Beast reference books: Obtained from Yu Xiaogang by Xu Qing and Xin after their confrontation 4 9.
• Mask: Worn before attempting Luo Sanpao’s attack at Xu Qing’s home 4.

Relationships

• Tang San — Disciple and intended proof of his theories. Tang San trusts his cultivation advice and later performs the emergency amputation that saves his life 7 8 10.
• Flender — Close friend and protector. Flender shelters him, assists with Tang San’s ring hunt, rescues him from the Cave Demon Spider, and feels responsible for his injuries 8 9 10 16.
• Xu Qing — Failed recruitment target turned enemy. Xu Qing rejects his instruction, has him subdued, and sells him to Brother Scar’s group; Yu Xiaogang subsequently vows revenge 4 5 6.
• Xin — Xu Qing’s protector. Yu Xiaogang mistakes her for a powerless slave; she knocks him unconscious and has a puppet carry him away 4.
• Brother Scar and the Rose Boy Band — Captors who purchase him and call him “Rose.” He deceives them into temporarily releasing him, then flees Nuoding City 5 6 7 9.
• Xiao Wu — Rejects his claim that she has twin Martial Souls and resents his dismissal of her Soft Bone Rabbit. She nevertheless follows the group to Shrek after he offers food and lodging 16.
• Bibi Dong — Past romantic connection, according to Xu Qing. Xu Qing believes Tang Hao wants to exploit this connection to obtain knowledge about cultivating twin Martial Souls 9.
• Liu Erlong — Someone Yu Xiaogang has previously met. Flender repeatedly worries about how his permanent injury will affect their future and how to explain it to her 4 10 16.
