Background / History

Yu Xiaogang intervenes when Tang San is blocked from entering Notting Academy, arranges his enrollment, and becomes interested in the unusual combination of Blue Silver Grass and innate full soul power. He explains that he wants to understand why Tang San possesses such an abnormal martial soul configuration. 3

He accepts Tang San as a disciple despite his own reputation for theoretical knowledge rather than practical strength. Tang San chooses him because Yu Xiaogang recognized that Blue Silver Grass could still have a viable cultivation path. 4 5

Yu Xiaogang prepares Tang San for his first soul-ring hunt by teaching him the Ten Core Competencies of Martial Souls, assigning him an illustrated soul-beast guide, and leading him into Soul Hunting Forest. 5 6

During preparations for the Soul Hunting Forest expedition, Ji Yuan covertly places an offspring spore in Yu Xiaogang's clothing. Yu Xiaogang remains unaware of the parasite and its later role in Ji Yuan's information network. 6

After Tang San's recurring soul-power depletion worsens, Yu Xiaogang concludes that the overbearing Clear Sky Hammer is consuming power needed by Blue Silver Grass. He arranges a journey toward Star Dou Great Forest in search of stronger life force and a more suitable soul ring to stabilize Tang San's mutation. 29 30

Yu Xiaogang later joins Shrek Academy, where he resumes direct oversight of Tang San after the students return from Star Dou Great Forest. He identifies Tang San's Eight Spider Lances as an External Soul Bone and assumes responsibility for training the Shrek Seven Devils. 82 83 84

Personality

Yu Xiaogang is serious, analytical, and deeply invested in proving and applying his theories. He emphasizes preparation, survival, and selecting soul rings that suit a martial soul rather than recklessly pursuing higher age limits. 5 7

He is genuinely protective of Tang San, repeatedly warns him against overexertion, and accepts responsibility when his own judgment proves inadequate. 7 12 25

His confidence in theoretical explanations can also become a blind spot. He repeatedly attributes Tang San's unexplained weakness, lost power, and nearby soul-power drain to conflict between Tang San's twin martial souls, unknowingly providing cover for Ji Yuan's parasitism. 8 13 21 24 25

Yu Xiaogang is willing to challenge and revise his earlier conclusions when Tang San's condition develops beyond ordinary twin-martial-soul theory. However, he continues to fit increasingly unusual evidence—including venomous shed tissue, plant-related phenomena, and the Eight Spider Lances' devouring behavior—into his evolving theory of martial-soul rejection. 48 83 84 90 92

He is demanding but impartial as an instructor. His training requires even support-system soul masters to push through physical exhaustion, and he treats endurance, judgment, coordination, and teamwork as essential parts of cultivation. 85 86

Yu Xiaogang's normally restrained demeanor becomes visibly affected by matters involving the Blue Lightning Tyrant Dragon Clan. He particularly wants Shrek Academy to defeat Yu Tianheng, though he avoids discussing the full nature of their family connection. 94

Abilities & Skills

Martial Soul Theory

Yu Xiaogang possesses extensive knowledge of martial souls, soul rings, soul beasts, toxin tolerance, and cultivation risks.

• Oversees Dai Mubai's recovery after the Eight Spider Lances drain part of his White Tiger origin, prescribing daily circulation with Tang San's Blue Silver Grass to stabilize Dai Mubai's meridians. 90 93

Training and Tactical Instruction

After assuming command of the Shrek Seven Devils' training, Yu Xiaogang develops their physical endurance, coordination, and team discipline.

• Assigns weighted bamboo baskets according to each student's martial soul path and physical condition. 85
• Requires the students to complete repeated runs between Shrek Academy and Suotuo City without Soul Power or discarded weight. 85 86
• Records the students' conditions and encourages them to exceed the premature exhaustion signals of their bodies without relying on external support. 86

Relationships

• Tang San — Disciple. Yu Xiaogang arranges his enrollment, gives him the Twenty-Four Moonlit Bridge, teaches him martial-soul theory, and guides his first soul-ring hunt. He later identifies Tang San's Eight Spider Lances as an External Soul Bone, imposes restrictions on Tang San's dangerous abilities, and remains committed to treating his increasingly abnormal condition. 3 5 6 82 83 84
• Xiao Wu — Tang San's protective friend. She frequently challenges Yu Xiaogang when she believes his examinations or explanations have endangered Tang San. Although their relationship remains tense, Yu Xiaogang recognizes her concern and includes her in Tang San's care and Shrek's training. 13 21 25 30 84
• Luo Sanpao — Accompanies Yu Xiaogang during the Soul Hunting Forest expedition and assists in checking their campsite. 7
• Matthew Nuo — Spirit Hall deacon who acknowledges that Yu Xiaogang's theories are not entirely empty after learning Tang San's Datura Snake soul ring was chosen by him. 16
• Su Yuntao — Spirit Hall representative who disparages Yu Xiaogang's strength and theoretical standing while trying to recruit Tang San. 17
• Flender — Shrek Academy's dean and Yu Xiaogang's associate. Flender supports Yu Xiaogang's evaluation of Tang San's External Soul Bone, though he challenges Yu Xiaogang when Dai Mubai is severely injured. 82 83 90
• Zhao Wuji — Shrek Academy teacher. Zhao Wuji initially questions Yu Xiaogang's explanations for Tang San's abnormalities, but relies on his knowledge of External Soul Bones and training management. 48 82 90

• Dai Mubai — Student under Yu Xiaogang's training. Following Dai Mubai's injury from Tang San's uncontrolled Eight Spider Lances, Yu Xiaogang defends Tang San from accusations of deliberate harm, accepts partial responsibility for the training arrangement, and supervises Dai Mubai's recovery. 90 93
• Zhu Zhuqing — A Shrek student who remains suspicious that Tang San may be parasitized by an unknown plant-like entity. Yu Xiaogang repeatedly rejects her suspicions in favor of his martial-soul-rejection theory. 48 75 84 90
• Yu Tianheng — A member of the Blue Lightning Tyrant Dragon Clan and Yu Xiaogang's relative by clan. Yu Xiaogang's personal history with the clan motivates his desire for Shrek Academy to defeat Yu Tianheng's Emperor Team. 94

Story Role / Major Arcs

Tang San's Enrollment and Apprenticeship

Yu Xiaogang admits Tang San to Notting Academy, accepts him as a disciple, and begins teaching him the principles needed to develop Blue Silver Grass and manage his hidden second martial soul. 3 5

Soul Hunting Forest Expedition

He escorts Tang San into Soul Hunting Forest, establishes camp precautions, confronts the Netherworld Wolf pack and Datura Snake, and is poisoned during the battle. Tang San later supports him while they leave the forest. 7 8 9 11 12

Explaining Tang San's Abnormalities

After Tang San repeatedly loses strength, vomits black blood, and experiences loss of control, Yu Xiaogang attributes the symptoms to conflict between Blue Silver Grass and the Clear Sky Hammer. These explanations strengthen Tang San's trust while concealing Ji Yuan's interference. 13 17 21

Investigation of Notting Academy's Soul-Power Drain

Yu Xiaogang investigates weakened upperclassmen and fluctuations detected around the Seventh Dormitory. Though he suspects Tang San’s abnormal martial-soul state may be involved, he concludes that resonance and twin-martial-soul imbalance are the likely causes. 24 25

Blood Ginseng Incidents

When Tang San is framed through purchases of hundred-year blood ginseng, Yu Xiaogang attempts to protect him and investigate the source. He eventually considers that a parasitic soul beast or special martial soul may be draining medicinal power from a distance, but does not identify Ji Yuan. 26 27

Star Dou Great Forest Proposal

When Tang San's Soul Power remains abnormally depleted and his left hand begins manifesting the Clear Sky Hammer's oppressive aura, Yu Xiaogang concludes that a stronger source of life force is needed. He plans a carefully supplied expedition to the outskirts of Star Dou Great Forest to stabilize Tang San's evolving Blue Silver Grass. 29 30

Residual Venom and Theoretical Reassurance

At Shrek Academy, Yu Xiaogang explains Tang San's black blood, venomous shed tissue, and renewed weakness as delayed Datura Snake venom expulsion compounded by twin-martial-soul conflict. His explanation persuades Zhu Zhuqing to withdraw her immediate accusations and allows Tang San to continue testing himself in the Great Soul Arena. 48

Identification of the External Soul Bone

After Tang San returns from Star Dou Great Forest with a Man Faced Demon Spider soul ring and eight retractable spider lances, Yu Xiaogang conducts repeated observations and identifies the lances as an External Soul Bone. He warns Tang San that its potential is extraordinary but that its growth and fusion create new risks. 82 83

Advanced Rejection Theory

Yu Xiaogang determines that Tang San's Clear Sky Hammer and External Soul Bone are rejecting one another, with Blue Silver Grass caught between them. He forbids Tang San from deliberately using the Clear Sky Hammer, limits use of the Eight Spider Lances, and dismisses Zhu Zhuqing's parasitism theory as unsupported by the evidence. 83 84

Shrek Seven Devils Training

Yu Xiaogang takes charge of the Shrek Seven Devils' training, beginning with weighted endurance runs between Shrek Academy and Suotuo City. His regimen emphasizes physical foundations, perseverance, coordination, and mutual support while accommodating Tang San's restrictions. 84 85 86 87

Dai Mubai's Injury and Recovery

When Tang San's Eight Spider Lances attack Dai Mubai during sparring and drain a large portion of his White Tiger origin, Yu Xiaogang attributes the incident to the Man Faced Demon Spider's bloodthirsty instinct being triggered amid external-soul-bone rejection. He accepts responsibility for underestimating the danger, suspends Tang San from combat training, and develops a recovery plan based on Blue Silver Grass's apparent life-attribute compensation. 90 92 93

Preparation for Emperor Team

Yu Xiaogang analyzes Emperor Team before Shrek Academy's upcoming Soul Battle. His personal connection to Yu Tianheng and the Blue Lightning Tyrant Dragon Clan sharpens his resolve, while his tactical guidance focuses on exhausting Yu Tianheng's Soul Power and preventing Tang San from relying on the unstable Eight Spider Lances. 94

Trivia

• Ji Yuan considers Yu Xiaogang especially useful because his theories consistently rationalize the effects of Ji Yuan's hidden parasitism. 4 8 13 21
• Yu Xiaogang’s concern for Tang San is sincere, even when his examinations inadvertently worsen Tang San’s condition. 25
• Ji Yuan covertly places an offspring spore on Yu Xiaogang before the Soul Hunting Forest expedition, but Yu Xiaogang never detects it. 6
• Yu Xiaogang's explanation that Tang San is affected by twin-martial-soul and External Soul Bone rejection remains persuasive enough that Tang San repeatedly trusts it over Zhu Zhuqing's suspicions. 75 84
