Power Progression

Background / History

Yu Xiaogang is the second son of the Blue Lightning Tyrant Dragon Sect’s leader. Stuck at level 29 for more than a decade, he left the sect and stayed away for over ten years because he believed returning would bring humiliation 31 70 71.

At Nuoding Academy, he intervened when a gatekeeper shoved Old Jack and escorted Ye Lin and Tang San inside. He discovered that he could hear Tang San’s unspoken thoughts, including his memories of a previous life and his contempt for Yu. Rather than take Tang San as his disciple, Yu chose Ye Lin, whose rare Body Martial Soul interested him 2 3.

Yu overheard and recorded Tang San’s Mysterious Heaven Skill. When he later tried it himself, the bottleneck at level 29 began to loosen. He passed the method and other techniques learned from Tang San’s thoughts to Ye Lin 6 8 9. Six years later, Yu was directing most of Shrek Academy’s courses and leading its Seven Devils team 23 71.

After reuniting with his nephew Yu Tianheng, Yu agreed to return to the sect once he had finished his work at Shrek. Tang San’s thoughts had also warned him that Spirit Hall would destroy the clan in a future Soul Hunting Operation 70 71.

Preparations to Leave Shrek

Yu proposed sending Shrek’s students to Heaven Dou Royal Academy to use its Mimicry Training Ground and enter the following year’s Advanced Soul Master Academy Tournament. He pointed out that Shrek was unregistered and lacked specialized training facilities. Flender accepted on the condition that all eight students and six teachers could move together and retain control of their students’ instruction, while Qin Ming agreed to arrange the necessary facilities, accommodation, and tournament registration 72.

During the preparations, Yu learned from Tang San’s thoughts that Qian Xunji had sexually assaulted Bibi Dong and manipulated her into ending their relationship despite her continued love for him. He also learned that Liu Erlong had waited twenty years for him. Recognizing that he had misunderstood Bibi Dong’s rejection and left both women suffering, he resolved to make amends. His contemplated visit to Spirit Hall would therefore serve more than his original purpose of obtaining protection for Ye Lin 75.

After returning to Shrek, Yu spent a month cultivating in seclusion with Luo Sanpao. He reached level fifty on the same day Yu Tianheng reached level forty. Accompanied by Flender, Ye Lin, and Tianheng, he entered the Star Dou Forest to obtain his fifth Spirit Ring. Absorbing the Ten Thousand Year White Python’s ring nearly overwhelmed him, but memories of his father, Bibi Dong, Liu Erlong, and Ye Lin strengthened his determination. The successful absorption also stabilized Luo Sanpao’s dragon form 76 77 78.

Return to the Blue Lightning Tyrant Dragon Sect

Yu traveled to the sect with Ye Lin and Yu Tianheng on Luo Sanpao’s back. Guard Captain Shi recognized him and addressed him as Second Master, although many younger disciples did not know that the sect leader had a second son. His name had largely disappeared from discussion during his absence 79 80.

He reunited with his elder brother and knelt before his father, Yu Yuanzhen, apologizing for leaving. Father and son embraced and acknowledged their regrets. Yu Luomian opposed his return, citing his removal from the clan rolls, former low cultivation, and defective Martial Soul. Yu answered by displaying five Spirit Rings and summoning Luo Sanpao as the Radiant Sacred Dragon. Yu Yuanzhen then formally reinstated him in the family 80 81.

Yu also defended Ye Lin’s place in the sect when Yu Luomian challenged the admission of an outsider. He cited his disciple’s age, cultivation, and victory over Yu Tianheng, which Tianheng personally confirmed. Yu Yuanzhen subsequently recognized Ye Lin as family, fulfilling Yu Xiaogang’s intention to give his disciple a protective identity 81.

During the visit, Yu explained Luo Sanpao’s bloodline development to his father. When Ye Lin later offered him the inherited dragon-type Spirit Bone received from Yu Yuanzhen, Yu declined, judging that it would benefit the boy more despite its potential to improve his own Martial Soul. Before leaving for Heaven Dou Royal Academy, he also asked his father to search for whale rubber 82 84 85.

Heaven Dou City and Reunion with Liu Erlong

Yu and Ye Lin rejoined Flender’s group outside Heaven Dou City. At Heaven Dou Royal Academy, Tang San’s thoughts and Xiao Wu’s behavior led Yu to deduce that she was a transformed Hundred Thousand Year soul beast. He treated this discovery cautiously 85 88.

The confrontation at the royal academy made Yu recognize that Ye Lin’s sect identity could deter lesser adversaries but was insufficient protection against a Titled Douluo. During the destruction of the teaching building, Luo Sanpao caught several students and carried them to safety 90.

After the group left, Yu learned through Tang San’s thoughts that Liu Erlong was at Blue Tyrant Academy. He had originally intended to visit Bibi Dong before searching for Erlong, but now resolved to meet her immediately. With Flender’s assistance, he and Liu Erlong reunited and reconciled despite Tang San’s intention to interfere. Liu Erlong handed leadership of Blue Tyrant Academy to Flender and welcomed Ye Lin as Yu’s disciple 92 94 95.

Dugu Bo and the Ice and Fire Yin Yang Well

While staying at Blue Tyrant Academy, Yu planned to secure the immortal herbs at the Ice and Fire Yin Yang Well before Tang San could claim them. When Dugu Bo abducted Ye Lin, Yu identified the kidnapper from the residual poison’s scent. He joined Liu Erlong and Flender in confronting Dugu Bo, using their Trinity Martial Soul Fusion Skill to empower Luo Sanpao. Believing his disciple remained in danger, he eventually abandoned defense for a desperate assault 97 100 102.

At the Ice and Fire Yin Yang Well, Yu identified Dragon Soul Grass and proposed a treatment for Dugu Bo’s accumulated poison. Rather than remove the poison at the cost of Dugu Bo’s cultivation, he suggested gradually transferring it into a Spirit Bone with medicinal assistance. Dugu Bo accepted and offered him access to the valley’s medicinal plants 106.

After Liu Erlong, Flender, and Yu Yuanzhen helped secure the valley, Yu sent them away and remained with Ye Lin. He directed his disciple to absorb the Octagonal Mysterious Ice Grass and Infernal Delicate Apricot in the spring and later consume the dew of Full Moon Wearing Autumn Dew. He himself refined Dragon Soul Grass through Luo Sanpao, reaching level fifty-two 107 110 112.

His treatment relieved Dugu Bo’s pain, shifted toxins away from his meridians, and loosened his cultivation bottleneck. By the end of the six-month treatment, Dugu Bo reported that the pain had disappeared, his Soul Power had reached level ninety-two, and his Martial Soul had evolved into the Jade Phosphorous Flood Dragon Emperor 112 115 120.

Return to the Renamed Shrek Academy

Yu and Ye Lin returned after half a year to find Blue Tyrant Academy renamed Shrek Academy. Liu Erlong greeted Yu with an embrace, and Flender arranged a welcoming dinner. At the meal, Yu announced that Ye Lin had brought medicinal herbs to help the students improve their talent and overcome bottlenecks. Although Yu had taught Ye Lin the herbs’ uses, he deliberately let his disciple receive the recipients’ gratitude 121 122.

After several students reached cultivation bottlenecks, Yu explained that training without immediately obtaining another Spirit Ring would not waste their Soul Power; the accumulated gains would manifest after absorption. He agreed to wait until the group was ready before arranging a collective Spirit Ring hunt 126.

Appearance

Yu Xiaogang has a lean face and is seen wearing a gray robe. Years after Ye Lin first meets him, he carries himself with noticeably greater energy and confidence 20 22.

• Bearing — Often stands with his hands clasped behind his back 20 22.
• Martial Soul — Luo Sanpao initially appears as a small, round yellow creature with short legs and drooping ears. After absorbing the White Python’s dragon bloodline, it can maintain a golden-scaled, winged Radiant Sacred Dragon form. Following further Dragon Soul Grass refinement, it develops lustrous platinum scales and grows considerably larger 70 78 80 112 120.
• After reaching level fifty — His complexion becomes rosier, his gaze brighter, and his posture straighter 76.
• Clothing condition — Before reuniting with Liu Erlong, his gray robe is described as faded almost white from washing, with a poorly mended tear in one cuff 93.

Personality

Yu is protective of Ye Lin: he arranges stronger supervision for their first Spirit Ring hunt, guards him during a Spirit Bone absorption, and warns him to conceal abilities that could put him in danger 5 21. He also accepts responsibility beyond his own group, offering to help Meng Yiran find a replacement Spirit Ring after Shrek kills the serpent she was tracking 31.

He is less open-handed toward Tang San. Hearing Tang San’s hostility, Yu rejects him as a disciple and quietly uses his thoughts to obtain techniques and information for Ye Lin. His regained confidence does not erase his concern for family; Tianheng’s plea and the threat to the sect move him toward returning home 3 6 29 70.

His concern for Ye Lin extends beyond cultivation to social standing and long-term security. Having suffered for his own pride, he seeks powerful backing for his disciple and refuses to let Ye Lin repeat his losses. He later declines a dragon-type Spirit Bone that could improve Luo Sanpao, placing the boy’s future ahead of his own advancement 71 84.

Yu is capable of acknowledging emotional mistakes. Learning the truth behind Bibi Dong’s separation and Liu Erlong’s long wait leaves him blaming himself and determined to make amends. Unlike the avoidance Tang San expects from his previous life, he approaches Liu Erlong and accepts their reunion 75 94 95.

His loyalty can become uncompromising when Ye Lin is threatened. Against Dugu Bo, he risks himself in a sustained attack after being led to believe his disciple remains in danger. He is also willing to work patiently and pragmatically afterward, preparing Dugu Bo’s medicine and overseeing the students’ future opportunities 102 106 112 122.

Abilities & Skills

Hearing Tang San’s Thoughts

Yu can hear thoughts Tang San does not speak aloud. He uses them to learn about Tang San’s previous life, record techniques, and anticipate dangers or opportunities 2 6 29.

• Records the Mysterious Heaven Skill and the Godly Zhuge Crossbow’s construction method from Tang San’s recollections 6.
• Learns of the hidden right leg Spirit Bone and Tang San’s plan to claim the Eight Spider Lances 7 29.
• Uses Tang San’s expectation of a Mandala Snake encounter to arrange for Headmaster Sigma to accompany the first Spirit Ring hunt 3 5.
• Learns of the Blue Lightning Tyrant Dragon Sect’s destruction in Tang San’s previous life, the circumstances of Bibi Dong’s separation from him, and Liu Erlong’s location and continued attachment 70 75 92.
• Accumulates descriptions and medicinal knowledge concerning immortal herbs over six years of listening. Although some details remain unclear to him, he can identify most of the relevant herbs from their recorded characteristics 97.
• Deduces Xiao Wu’s soul-beast identity by connecting Tang San’s references to sacrifice with her safe return from the Titan Giant Ape 88.
• Attracts suspicion from Oscar and the other students when his warning about an arena opponent closely matches Tang San’s thoughts. He responds by presenting his prediction as an analysis of local Soul Master statistics and arena records 52 53.

Martial Soul Theory and Instruction

Yu specializes in assessing Martial Souls, Spirit Rings, and combat roles 6 31 32.

• Recommends a strength-focused assault path with defensive attributes for Ye Lin’s Body Martial Soul 6.
• Sets Ye Lin a third-ring target of at least 5,000 years, accounting for his body, Martial Soul, and Spiritual Power 32.
• Teaches support-type students divided attention and advises Zhu Zhuqing to turn speed into accurate, decisive attacks 46.
• Identifies the limits of Oscar’s antidote and the threats posed by the Imperial Fighting Team 60 61.
• Stops Meng Yiran from absorbing a Man Faced Demon Spider’s Spirit Ring after identifying the beast as at least 2,200 years old and judging it beyond her safe absorption limit 37.
• Advises Ye Lin to present the Dark Gold Dreadclaw as his Martial Soul, reasoning that the rarity of Body Martial Souls will keep observers from recognizing it as an External Soul Bone 43.
• Explains that Soul Power cultivated at a bottleneck is retained and can produce additional level gains once the required Spirit Ring is absorbed 126.

Cultivation

The Mysterious Heaven Skill enables Yu to advance beyond his longstanding level-29 bottleneck. Luo Sanpao can cultivate the same method, nearly doubling their combined cultivation speed 8 71.

Luo Sanpao also feeds absorbed dragon-bloodline power back to Yu. Refining Dragon Soul Grass raises him from level fifty-one to fifty-two and improves his physical strength, meridian resilience, and bone density 112.

Luo Sanpao and Dragon-Bloodline Evolution

Luo Sanpao can absorb dragon bloodlines, changing incrementally with each absorption. By Yu’s third Spirit Ring, it can assume a Radiant Sacred Dragon form while using a Spirit Skill. The dragon bloodline obtained with his fifth ring stabilizes that form outside skill activation, though Yu states that Luo Sanpao is not yet a completely pure Radiant Sacred Dragon 78 82.

• Holy Flame of Light — His third Spirit Skill. Luo Sanpao transforms into a large golden creature with powerful limbs, broad wings, and a curved forehead horn, then uses holy flame to burn a Man Faced Demon Spider’s poisonous web 37.
• Draconic might — Its roar causes soul beasts across dozens of miles of the Star Dou Forest to freeze. Its superior bloodline also places instinctive pressure on the Blue Lightning Tyrant Dragon Sect’s disciples and elders 78 81.
• Flight and transport — Carries Yu, Ye Lin, and Yu Tianheng through the air. It also rescues several Shrek students during the collapse at Heaven Dou Royal Academy 79 90.
• Dragon Soul Grass refinement — Consumes the herb to strengthen its bloodline and body. Continued feeding produces substantial growth over six months 112 120.

Trinity Martial Soul Fusion Skill

As members of the Golden Iron Triangle, Yu, Flender, and Liu Erlong can perform a Trinity Martial Soul Fusion Skill. They form a triangle with Yu at the front, while Flender and Liu Erlong channel their Soul Power into him. Luo Sanpao expands under their combined power. They use this technique against Dugu Bo while attempting to rescue Ye Lin 95 100.

Medicinal Knowledge and Detoxification

Using knowledge accumulated from Tang San’s thoughts, Yu recognizes immortal herbs and understands methods for processing them. He identifies Dragon Soul Grass as containing a pure dragon bloodline and directs Ye Lin’s use of the Ice and Fire Yin Yang Well’s rare herbs 97 106 107 112.

• Identifies the Octagonal Mysterious Ice Grass and Infernal Delicate Apricot as capable of removing Dugu Bo’s poison, but warns that this approach would also destroy his poison cultivation 106.
• Develops a medicinal treatment that gradually moves Dugu Bo’s poison into a Spirit Bone instead, preserving his cultivation while reducing his pain 106 112.
• Produces antidote doses that ease Dugu Bo’s symptoms and loosen his cultivation bottleneck; Dugu Bo later reports complete relief from the pain and advancement to level ninety-two 112 115 120.
• Teaches Ye Lin the properties of the medicinal herbs brought back for the Shrek students 122.

Team Strategy

Yu plans Shrek’s training and arena battles, including pair assignments and rotation among its support-type members 23 52.

• Designs the Mad Battle Team tactics around preventing its Ruyi Plate Soul Master from activating Frenzy 58.
• Appoints Ye Lin to direct the Seven Devils, citing his Mind Split into Five Uses training 59.
• Conceals the students’ strength during arena matches; he later reveals that he borrowed from Spirit Hall and bet on the team’s success 52 54.
• Provides costly medicinal baths after exhausting team training, intending arena earnings and betting proceeds to offset the expense 51.
• Advocates access to Heaven Dou Royal Academy’s facilities and tournament eligibility rather than allowing attachment to Shrek’s independence to limit the students’ development 72.
• Arranges a collective Spirit Ring hunt once the students have reached their respective bottlenecks 126.

• Twenty-Four Bridges Bright Moon Night — A storage belt Yu gives Ye Lin; its twenty-four gems each hold one cubic meter 6.

• Tai Chi-shaped jade pieces — Two pieces he gives Dai Mubai and Zhu Zhuqing before the Imperial Fighting Team match 60.

• Medicinal herbs and antidotes — Uses the valley’s plants to prepare Dugu Bo’s treatment and helps select medicinal herbs for Shrek’s students 106 112 122.

Relationships

• Ye Lin — His direct disciple, chosen over Tang San. Yu trains and protects him, provides Spirit Bones, and plans to give him a respected identity through the Blue Lightning Tyrant Dragon Sect; he regards Ye Lin as his own child 3 21 44 71. He fulfills that plan by defending Ye Lin before the sect and securing Yu Yuanzhen’s recognition. Ye Lin, in turn, offers him a valuable dragon-type Spirit Bone, which he declines. Yu later risks his life against Dugu Bo to rescue him and lets Ye Lin receive credit for the medicinal herbs brought back to the students 81 84 100 102 122.
• Tang San — Yu rejects him as a disciple after hearing his contempt, but repeatedly uses knowledge from Tang San’s thoughts 2 3 6 29. Later revelations about Tang San’s previous-life manipulation and present intention to obstruct his relationship with Liu Erlong reinforce his relief at having rejected him. Tang San also views Ye Lin’s abduction as an opportunity to hurt Yu by eliminating his disciple 92 97.
• Yu Tianheng — His nephew. They reunite after more than ten years apart, and Yu comforts him following the Imperial Fighting Team’s defeat 70 71. Tianheng temporarily studies at Shrek, reaches level forty, and accompanies Yu and Ye Lin on their Spirit Ring hunt and return to the sect 73 76 79.
• Flender — His longtime friend and Shrek Academy colleague. Flender supports Yu’s teaching authority and notices his renewed confidence 23 31. He guards Yu during his fifth-ring absorption, helps bring about his reconciliation with Liu Erlong, and fights alongside him to rescue Ye Lin from Dugu Bo 78 94 95 100.
• Bibi Dong — A former love whom Yu has not forgotten; Tang San’s stated intention to kill her angers him 3. She previously supplied him with Martial Soul theory books from Spirit Hall. After learning from Tang San’s thoughts about Qian Xunji’s abuse and manipulation, Yu realizes he misunderstood their separation and resolves to make amends 75 78.
• Liu Erlong — His cousin, former bride, and fellow Golden Iron Triangle member. After learning that she has waited twenty years for him, Yu reunites and reconciles with her at Blue Tyrant Academy. She recognizes Ye Lin as the disciple of her husband, assists in his rescue, and embraces Yu when he returns from his six-month stay at the Ice and Fire Yin Yang Well 75 78 88 95 100 121.
• Yu Yuanzhen — His father. Their estrangement ends in an emotional reunion and mutual expressions of regret. Yu Yuanzhen restores him to the family, recognizes Ye Lin as a grandson, and later assists the group at the Ice and Fire Yin Yang Well 80 81 107.
• Elder brother — Yu Tianheng’s father. He embraces Yu on his return and reproaches him for staying away so long, while warning that his return may provoke opposition within the sect 66 80.
• Yu Luomian — His second uncle and Liu Erlong’s father. He opposes Yu’s reinstatement and challenges Ye Lin’s admission to the sect. Yu counters his objections with his improved cultivation, Luo Sanpao’s dragon form, and Ye Lin’s accomplishments 80 81.
• Dugu Bo — Initially an adversary who abducts Ye Lin and fights the Golden Iron Triangle. He later accepts Yu’s poison-treatment plan and grants access to the valley’s medicinal plants. Yu’s medicine relieves his chronic pain and helps loosen his cultivation bottleneck 97 100 106 112 120.
• Xiao Wu — One of Shrek’s students and Ye Lin’s close companion. Yu deduces that she is a transformed Hundred Thousand Year soul beast and recognizes the need for caution in handling that knowledge 88.
• Sigma — Nuoding Academy’s headmaster, whom Yu asks to protect the boys during their first Spirit Ring hunt 5 6.
• Chao Tianxiang and Meng Yiran — Yu offers to help find Yiran a suitable Spirit Ring as compensation for the serpent Shrek killed 31 32. He later protects Yiran from a poisonous web and prevents her from absorbing an excessively old Spirit Ring, earning thanks from her grandparents 37.
