Yu Xiaogang

Biodata

Power Progression

Personality

Yu Xiaogang presents himself as a learned, misunderstood theorist, but his private thoughts reveal calculated self-interest. He courts Bibi Dong partly to obtain Spirit Hall’s resources, then treats Liu Erlong as a romantic fallback and a means of retaining control over the Golden Iron Triangle. When his reputation collapses, he performs guilt and distress to secure his companions’ sympathy 5 7 9 46.

His pride in his theoretical reputation coexists with deep resentment over being considered weak. Although he promotes the idea that ordinary Soul Masters need not be worthless, he rejects a child claiming to possess an inferior Martial Soul and privately seeks an exceptionally gifted disciple who can vindicate his name 5.

He is possessive toward Bibi Dong even after their breakup, interpreting her closeness with Xu Feng as a personal betrayal. His determination to avenge himself does not overcome his fear of death: during pursuit, he continues fleeing while relying on Liu Erlong to hold off their attackers 9 11 52.

Abilities & Skills

Soul Master Theory

Yu Xiaogang possesses extensive knowledge of Martial Souls and cultivation, but much of it comes from Spirit Hall’s ancient texts supplied by Bibi Dong. He consolidates and applies that material while falsely claiming independent authorship 7 8 46.

• Published theories: His credited work includes the Ten Core Competitive Theories and proposed limits on the Soul Ring ages each rank can absorb 8 9.
• Martial Soul analysis: He recognizes Liu Erlong’s Martial Soul as a mutation of the Blue Lightning Tyrant Dragon 43.
• Research limitations: Despite his reputation, he cannot resolve his own Martial Soul defects 5 53.
• Unsupported promises: He offers to find compatible fusion partners for Bibi Dong, but Xu Feng identifies this as an empty promise given the exceptional nature of her Twin Spider Emperor Martial Soul 10.

Golden Sacred Dragon

Yu Xiaogang develops the Golden Iron Triangle’s three-person Martial Soul Fusion Skill using knowledge derived from Spirit Hall’s heritage 7 10 46.

• Participants: Yu Xiaogang, Flender, and Liu Erlong.
• Manifestation: A Golden Sacred Dragon, with the three participants positioned in a triangular formation atop its head 7.
• Combat performance: The group becomes virtually undefeated against opponents within the same major realm and has considerable chances against opponents one major realm higher 43.
• Dependency: Maintaining the technique requires keeping both companions in the group. Yu Xiaogang avoids openly pursuing Liu Erlong partly because he fears Flender’s jealousy could break up the trio 47.

Heavenly Dao Protection

As Tang San’s intended teacher, Yu Xiaogang receives protection from the Heavenly Dao’s correction force. This is an external safeguard tied to his destined role, not a technique he controls 64.

• After his physical death, the force reforms his true spirit and attempts to arrange rebirth in another body with his memories intact 64.
• An ordinary dagger cannot harm his disembodied true spirit 64.
• A protective barrier blocks Xu Feng’s initial Black Heaven Demon Scythe attack 65.
• The protection ultimately fails to prevent his confinement in the Hell Cage, where Xu Feng’s control over undead souls supersedes the Heavenly Dao’s authority 69.

Equipment & Items

• Martial Soul Fusion research parchment — Records his method for three-person fusion. He offers it to Bibi Dong while seeking reconciliation; she destroys it with Soul Power 10.

Relationships

• Bibi Dong — Former lover and source of Spirit Hall’s ancient texts. She ends their relationship after testing his attitude toward ordinary Soul Masters and confirming his interest in using her access to resources. Their relationship becomes openly hostile 5 8 10 11.
• Liu Erlong — His cousin, admirer, and fusion partner. He conceals their familial connection and regards her as a fallback partner and tool for revenge. After gaining access to his memories and thoughts, she turns against him and becomes his torturer 10 43 78 79 80.
• Flender — Friend and fellow Golden Iron Triangle member. Flender initially advises him to abandon Bibi Dong and later questions the plagiarism evidence. Yu Xiaogang carefully manages Flender’s feelings for Liu Erlong to preserve the trio 7 47 53.
• Xu Feng — Principal enemy, captor, and killer. Xu Feng’s thoughts expose Yu Xiaogang’s motives to Bibi Dong; he later kills Yu Xiaogang and controls his undead existence in the Hell Cage 4 8 64 69.
• Tang San — Destined disciple rather than an actual student in the documented events. The Heavenly Dao shows Yu Xiaogang fragments of a future in which he teaches Tang San, leading him to expect revenge through Tang San’s eventual victory over Bibi Dong 64.
• Ning Fengzhi — Withdraws the Seven Treasure Glazed Tile Sect’s invitation for Yu Xiaogang to become a guest elder after reviewing evidence of plagiarism, then orders him blacklisted 46.
• Salas — Fellow Hell Cage prisoner whose punishments become tied to Yu Xiaogang’s. Salas resents being implicated and attacks him during his period of madness 89.

Story Role / Major Arcs

Breakup with Bibi Dong

Yu Xiaogang initially anticipates a date with Spirit Hall’s Saintess, taking pride in having won her affection. When she fails to appear, he waits outside Spirit Hall for five days. Guards beat him after dismissing his claim that he knows her, and he retreats to an inn to drink 2 5.

Warned by Xu Feng’s thoughts, Bibi Dong secretly pays a child to approach him as an untalented prospective disciple. Yu Xiaogang refuses the child, contradicting the ideals that originally attracted her. When she finally speaks with him, he asks to use Spirit Hall’s soul tools to repair his Martial Soul. She ends their relationship and leaves despite his pleas 4 5.

Formation of the Golden Iron Triangle

After the breakup, Yu Xiaogang drinks with Flender in Suotuo City and refuses to abandon hope of reclaiming Bibi Dong. The two meet Liu Erlong, who becomes impressed by his knowledge. Within a month, their Golden Sacred Dragon fusion brings them fame throughout the Heaven Dou Empire 7.

The success restores Yu Xiaogang’s confidence, but he privately dismisses Liu Erlong’s affection as easy to manipulate. He decides to keep her as a fallback while continuing to pursue Bibi Dong 7.

Failed Reconciliation and Mutilation

Yu Xiaogang returns to Spirit Hall intending to impress Bibi Dong with his fusion research, regain her sympathy, and resume obtaining ancient texts and healing resources through her. Instead, she arrives with Xu Feng, rejects his familiarity, destroys his research parchment, and forbids him from using theories taken from Spirit Hall’s texts 9 10.

Bibi Dong restrains him while embracing and kissing Xu Feng, then claims to be carrying her disciple’s child. The pregnancy claim is a deception intended to humiliate him. She subsequently breaks both of his legs, forces him to crawl, and castrates him 9 11 44.

Plagiarism Scandal and Flight

Yu Xiaogang returns to Liu Erlong while concealing his mutilation and their family connection. He sees her loyalty and the Golden Iron Triangle’s growing influence as his route to revenge 43.

More than half a year after their confrontation, Bibi Dong orders Spirit Hall to circulate evidence that his celebrated theories originated in its ancient texts. The scandal spreads across the Heaven Dou Empire within three days. The Seven Treasure Glazed Tile Sect withdraws its guest-elder invitation and blacklists him 44 46.

Yu Xiaogang denies responsibility to his companions and portrays himself as the target of Bibi Dong’s persecution. Liu Erlong remains devoted to him, while Flender questions the evidence. The group goes into hiding, and Yu Xiaogang later flees with Liu Erlong after learning of Spirit Hall’s pursuit 47 52 59.

Capture and Death

Xu Feng, Yue Guan, and Gui Mei corner Yu Xiaogang and Liu Erlong in a cave. During the ensuing humiliation, Bibi Dong disguises herself as Liu Erlong and approaches Xu Feng. Yu Xiaogang mistakes her for his companion and believes Xu Feng is taking another woman from him 58 59 61 62.

Xu Feng eventually crushes Yu Xiaogang’s head. The Heavenly Dao then reforms his true spirit and shows him fragments of his intended future as Tang San’s teacher. Convinced that rebirth and revenge are assured, Yu Xiaogang taunts Xu Feng with a vision of Bibi Dong dying beneath Tang San’s Asura Sword 64.

Xu Feng summons the Black Heaven Demon Scythe to attack his true spirit. After the correction force blocks the first strike, Xu Feng detonates four Soul Rings and invokes his eighth Soul Skill. Yu Xiaogang is subsequently confined as an undead soul in the Chaos Realm rather than receiving the rebirth he expected 65 69.

Hell Cage Imprisonment

Even in captivity, Yu Xiaogang initially insists that he will escape and that Tang San will avenge him. Xu Feng later extracts his memories and private thoughts for Liu Erlong, exposing his contempt for her and his use of her affection 69 78.

When Liu Erlong visits his cell, Yu Xiaogang immediately treats her arrival as an opportunity to escape. His outward promises of protection clash with thoughts celebrating the usefulness of his “backup.” Her discovery of his deception leads to brutal punishment under her authority as Hell Dragon Hunter 79 80.

Repeated torment leaves Yu Xiaogang mentally deranged. He begins welcoming blows and terrorizing other prisoners with feces, provoking a collective beating. By Chapter 118, he remains isolated in a filthy cell, gnawing on its bars 89 92 93 118.

Xu Feng uses him to test Ultimate Nightmare, earning Lying Flat Points from his suffering. The treatment unexpectedly restores Yu Xiaogang’s sanity, but does not free him from imprisonment or further exploitation 118.
