Background / History

Yu Xiaogang arrived at Nuoding Primary Soul Master Academy to considerable acclaim. The Old Dean and instructors treated him as a distinguished authority on martial soul theory, while he maintained the detached manner of an expert. Beneath this identity, however, a transmigrator had taken over his body and social position to a reported ninety percent degree through soul fusion. 25 26

His Luck Plunder System evaluated the aptitude and luck of nearby students. He disregarded ordinary prospects until it identified Tang Wu as an “immeasurable” target with Child of the Plane-level luck. Convinced that binding her as a disciple could remove his level-twenty-nine bottleneck and potentially elevate him to Titled Douluo, he targeted her immediately. 26 27

Appearance

Yu Xiaogang initially cultivated the image of a scholarly master, wearing a black robe and adopting a composed, aloof posture. 26 27

• Crew-cut hair and an intense, predatory gaze when focused on Tang Wu 27
• Wore a black robe and carefully adjusted its collar to reinforce his “Master” persona 26
• After the bathhouse incident, his robe was torn into rags; he was soaked, bruised, and left with a swollen left eye. 34
• System punishment later reduced him to a prematurely aged, mud-covered wreck outside Nuoding City. 35 39

Personality

Yu Xiaogang was ambitious, calculating, and deeply dependent on his system. He hid his greed behind the public reputation of “Grandmaster,” using polished theories, a private office, and the Old Dean’s endorsement to pressure Tang Wu into accepting him as her teacher. 27 28

His composure broke down when persuasion failed. He dismissed Tang Wu as foolish for ignoring his teachings, then resorted to the system’s Forced Apprenticeship Function to impose a master-disciple bond and harvest her luck. 28 29

When the altered system mission began controlling his body, Yu Xiaogang became frantic and cowardly. He repeatedly begged the system to change the task, knowing that public exposure would destroy the reputation he had built. 30 31

Abilities & Skills

Luck Plunder System

A dark-red system bound to Yu Xiaogang’s possessor. Its core function was to establish a causal master-disciple bond with a Child of Luck, then continuously drain the disciple’s luck, talent, and opportunities. 26

• Scanned nearby students for aptitude and luck value. 26
• Identified Tang Wu as a Child of the Plane-ranked target with immeasurable luck. 27
• Had no disciples bound before targeting Tang Wu. 26
• Held Yu Xiaogang at a luck value of 10, described as average-person level. 26
• Was vulnerable to Su Yu’s Conceptual Eraser, which could rewrite its task logic. 29 30
• Collapsed after mission failure and logical corruption, releasing an Origin Fragment after Yu Xiaogang’s death. 35 39 42

Forced Apprenticeship Function

The system’s coercive method for forming the plundering bond with Tang Wu. 28

• Required Yu Xiaogang to place his hand on the target’s head for three seconds. 28
• Would have forcibly completed the apprenticeship ceremony and opened a luck-plundering channel. 28
• Its mandatory mission promised Yu Xiaogang 50% of Tang Wu’s Luck Value upon success. 29
• The attempt immobilized Tang Wu and made her feel as though something was trying to strip away her soul and what she valued most. 29
• Su Yu interrupted and rewrote the mission before the ritual could be completed. 29 30

Martial Soul Theory

Yu Xiaogang publicly presented himself as a leading martial soul theorist and promoted his “Ten Core Competencies of Martial Soul.” 27 28

• Claimed that “there are no trash Martial Souls, only trash Soul Masters.” 27 28
• Argued that Blue Silver Grass possessed exceptional inclusivity and could absorb soul rings of any attribute. 28
• Promised Tang Wu ideal soul-ring ratios and Soul Ancestor-level advancement before age twenty if she became his disciple. 28
• Failed to gain any trust or favor from Tang Wu; his system recorded both values at zero. 28

Relationships

• Tang Wu — Intended disciple and primary plundering target; he attempted to forcibly bind her and take 50% of her Luck Value. 26 29
• Su Yu — Antagonist who exposed his system-driven scheme, rewrote his mission, and indirectly caused his downfall. 28 30 34 42
• Xiao Wu — Opposed his attempt on Tang Wu and prepared to attack him when she sensed the danger he posed. 27 29
• Old Dean — Initially flattered and promoted Yu Xiaogang’s reputation, then publicly condemned and expelled him after the bathhouse incident. 27 34
• Luck Plunder System — His source of power and ultimately the force that controlled, punished, and abandoned him after its logic failed. 26 30 35 39

Story Role / Major Arcs

Arrival at Nuoding Academy

Yu Xiaogang arrived as a celebrated “Grandmaster,” receiving a private office and the academy’s public respect. While the Old Dean praised his expertise, Yu Xiaogang used the opportunity to scan students for a suitable target for his Luck Plunder System. 25 27

Attempted Recruitment of Tang Wu

After detecting Tang Wu’s extraordinary luck, Yu Xiaogang approached her with offers of guidance and used his reputation to pressure her into visiting his office. He delivered a lengthy explanation of Blue Silver Grass’s supposed potential, but Tang Wu ignored him in favor of Su Yu. 26 28

Forced Apprenticeship Attempt

With persuasion unsuccessful, Yu Xiaogang activated the Forced Apprenticeship Function. His system issued a mandatory task to accept Tang Wu as a disciple and plunder half of her Luck Value, but Su Yu’s Conceptual Eraser altered the task before Yu Xiaogang could touch her. 28 29

Bathhouse Incident and Expulsion

The rewritten mission compelled Yu Xiaogang to run to the girls’ bathhouse and peep. Unable to control his body or conceal his identity, he was caught, beaten by female instructors and matrons, and publicly denounced by the academy. The Old Dean expelled him and had guards drag him from the grounds. 30 34

System Collapse and Death

Outside Nuoding City, the corrupted system’s penalty program rapidly aged and tortured Yu Xiaogang. He was left too weak to escape a mud pit, and his system ultimately crashed. Its remaining core energy became a grey-gold Origin Fragment that later reached Su Yu in the Soul Hunting Forest. 35 39 42
