Yu Xiaogang

Biodata

Power Progression

Background / History

Yu Xiaogang grows up largely within the Blue Lightning Tyrant Dragon Clan, usually accompanied by an elder when he travels outside. His father obtains medicinal ingredients and hires instructors to address his low aptitude, but nine years of effort yield only a breakthrough to level ten. Yu Xiaogang worries that those resources would have produced much better results for another clan member, yet continues studying and cultivating rather than giving up 1 17.

Li Qingshan finds him reading in the forest below the clan’s mountain and offers to help Luo Sanpao evolve. Yu Xiaogang challenges his claimed level-ninety-nine cultivation, unfamiliar title, youthful appearance, and apparently modest Soul Power. Only after witnessing overwhelming pressure and two Sword Martial Souls does he seriously consider the offer. Li Qingshan’s recognition of his painstaking research and perseverance finally persuades him to kneel and accept him as his teacher 1 2 3 4.

Within less than a year of becoming Li Qingshan’s disciple, his cultivation rises from level ten to level twenty-three, his innate aptitude improves, and Luo Sanpao becomes a Golden Sacred Dragon. He attributes these changes to his teacher’s medicine-seeking, pill refinement, and cultivation guidance, describing the help as equivalent to receiving a second life 68 71.

On returning to his clan, he demonstrates his evolved Martial Soul and thousand-year Second Soul Ring before his father and the elders. His return coincides with Li Qingshan’s efforts to arrange an alliance between the Blue Lightning Tyrant Dragon Clan and the Seven Treasure Glazed Tile Sect 90 91 92.

Appearance

Yu Xiaogang is introduced as a delicate-featured youth with short, slightly disheveled black hair 1.

• Clothing: A fine-fabric robe with intricate lightning embroidery around the collar 1.
• Initial demeanor: Drooping shoulders and a gloomy expression while reading alone 1.
• After training: A healthier appearance, lighter steps, and steady breathing even after descending the mountain path 6.

Personality

Yu Xiaogang is persistent, methodical, and willing to question authority. His notebooks combine excerpts on Soul Beasts with repeatedly revised observations about Luo Sanpao’s diet, training responses, and difficult points in Soul Power circulation. He does not accept Li Qingshan’s impressive title on its own, instead checking the claim against his reading and personal experience 2 4.

His skepticism gradually becomes deep trust as his teacher’s methods produce visible results. He follows instructions carefully, reports changes earnestly, and expresses concern when Li Qingshan undertakes further journeys on his behalf. By the time Li Qingshan claims to be an Alchemy Master, Yu Xiaogang believes him completely 10 21 48.

He values Luo Sanpao as a companion regardless of whether it becomes stronger. When clan youths mock his aptitude and Martial Soul, he refuses to argue or let their insults interrupt his training plans. He also recognizes the elders’ newly favorable treatment without becoming boastful or disrespectful 19.

His growing confidence does not displace his conscientiousness. Even while eager to meet Bibi Dong, he completes his teacher’s assigned breathing exercises first. Ning Fengzhi later praises his careful explanations and refusal to give unsupported answers; Yu Xiaogang credits Li Qingshan’s instruction that ignorance can be addressed by asking questions, but must not become a reason to teach others nonsense 68 92.

He is considerate of his companions and uncomfortable inconveniencing them for his own advancement. When Li Qingshan changes the group’s route to seek his Third Soul Ring, Yu Xiaogang hesitates over making everyone turn back on his account. He also supports accepting Liu Erlong as a disciple, emphasizing her diligence and care for the group 112 113.

His attachment to Bibi Dong reveals a more openly emotional side. He is delighted to receive her letter, becomes angry upon learning that Qian Xunji slapped her, and is visibly relieved when Li Qingshan brings her back safely 92 103.

Abilities & Skills

Luo Sanpao

Luo Sanpao is a mutated Martial Soul descended from the Blue Lightning Tyrant Dragon. Unlike an ordinary Beast Martial Soul, it can move independently, eat, and display its own thoughts and reactions 2 7.

• Independent manifestation: Appears as a plump golden puppy with yellow eyes before its dragon evolution 1.
• Diet-assisted growth: Dragon-type Soul Beast meat and blood improve its stamina and initiate scale growth 7 11.
• Reduced maintenance cost: Its initial evolution lowers the Soul Power required to keep it active outside Yu Xiaogang’s body 11.
• Evolution requirement: Meat, blood, and a compatible Soul Ring begin its transformation but are not sufficient to complete it; Li Qingshan turns to Immortal Herbs and medicinal pills 14 20 45.
• Second Soul Ring changes: Tiny arcs of lightning appear among its golden scales, while the light on its forehead and wings brightens during absorption of the Golden-Backed Thunder Dragon Beast’s ring 71.

Sacred Dragon Breath

Yu Xiaogang’s First Soul Skill channels Soul Power into Luo Sanpao, which releases a golden beam from its mouth 14.

• Demonstrated effect: Bursts apart the surface of a rock roughly half a person’s height, spreading cracks and throwing off fragments 14.
• Activation: Luo Sanpao braces its paws while its scales and Yu Xiaogang’s yellow Soul Ring glow 14.
• Training needs: Yu Xiaogang must measure its consumption, usable repetitions, and Luo Sanpao’s response afterward 14.
• Combat limitation: Testing it against a stationary rock does not establish his ability to hit moving enemies or protect himself during a fight 17.

Golden Sacred Dragon Form

Luo Sanpao’s evolved form is the Golden Sacred Dragon, also called the Radiant Sacred Dragon 12 45.

• Flight: The dragon form can spread its wings and fly 47 60.
• Transformation control: Yu Xiaogang eventually directs repeated changes between dragon and puppy forms without difficulty 60.
• Initial limitation: His one-and-a-half-level innate foundation cannot sustain the powerful Martial Soul for long; even a short flight exhausts his recovered Soul Power 47.
• Adaptation: Li Qingshan explains that his newly improved meridians must become accustomed to the dragon form’s Soul Power circulation 45.
• Precision exercises: Bibi Dong arranges stones at different positions and has him guide Luo Sanpao around them in order without collisions or wrong turns 68.
• Practical training: By his return to the clan, he has practiced both flight and fighting with Luo Sanpao’s dragon form 92.
• Close-combat development: Li Qingshan selects the Diamond Horned Dragon for his Third Soul Ring because its whole-body amplification suits the development of Luo Sanpao’s claws, wings, and dragon body alongside its ranged attacks. The resulting Soul Skill has not yet been confirmed 114.

Martial Soul Research

Yu Xiaogang uses written observation to guide his cultivation rather than relying solely on inherited clan methods 4 5.

• Records food intake, bodily changes, training results, and circulation difficulties 4 10.
• Tracks Luo Sanpao’s responses between feedings and brings the records to Li Qingshan for inspection 11.
• Reconsiders the clan’s standard Soul Ring choices because Luo Sanpao differs from an ordinary Blue Lightning Tyrant Dragon 5 12.
• Distinguishes improved innate aptitude from actual cultivation advancement after his innate Soul Power reaches five and a half levels and his cultivated Soul Power reaches level twenty 68.
• Explains his knowledge carefully and acknowledges uncertainty rather than providing speculative instruction as fact 92.

Trinity Martial Soul Fusion Skill

Yu Xiaogang, Flender, and Liu Erlong discover that their Soul Powers can circulate through one another’s meridians and merge. Their compatible Martial Souls produce a giant six-winged dragon, with Yu Xiaogang able to direct its movements 111 112.

• Initial manifestation: Their powers connect while the three are holding hands during training under Li Qingshan 111.
• Control: Yu Xiaogang can make the dragon lower its head and attempt an attack, but its six wings initially move out of coordination and its body sways 111.
• Consumption: Even a slight attempt to control the dragon rapidly drains his Soul Power. Flender and Liu Erlong likewise struggle to restrain their expenditure 111.
• Repeatability: Li Qingshan confirms that their compatibility will allow them to summon the dragon again, while stressing that manifestation is not the same as mastery 112.
• Training approach: The three practice blending, releasing, and withdrawing Soul Power before attempting further full manifestations. Over three days, they begin anticipating changes in one another’s Soul Power 112.

Equipment / Items

• Research notebook — His central record of Luo Sanpao’s condition and his own training; packed especially carefully before leaving the clan 4 19.
• Books, paper, and brushes — Taken on his journey alongside several changes of clothing 19.
• Storage Soul Tool — Used to store purchased Soul Beast meat and blood 24.

• Mystic Water Pill — Improves his meridians and innate aptitude 43 47.
• Sacred Dragon Creation Pill — Enables Luo Sanpao’s completed evolution, although some medicinal power remains unabsorbed afterward 45.
• Residual medicinal power — Power left by pills refined from Immortal Herbs gradually becomes available as his meridians adapt, contributing to his level-twenty breakthrough and subsequent rise to level twenty-three 68 71.
• Thousand-Year Dragon Scale Fruit — Consumed before his Third Soul Ring hunt and almost completely refined by the time Li Qingshan examines him for the five-thousand-year ring 114.
• Bibi Dong’s letter — Delivered to him at the Blue Lightning Tyrant Dragon Clan; describes her questioning and mistreatment after returning to Spirit City 91 92.

Relationships

• Li Qingshan — Teacher and the person who establishes his new cultivation path. Yu Xiaogang becomes deeply grateful for his guidance and worries about his safety during their travels. After reaching level twenty-three, he says that his teacher’s help is like giving him a second life. Li Qingshan continues checking his physical readiness before older Soul Ring absorptions and changes the group’s route rather than compromise the suitability of his Third Soul Ring 4 14 27 48 71 113 114.
• Yu Yuanzhen — Father and clan leader. Supports his cultivation for years, then approves his departure with Li Qingshan after witnessing his improvement. On his return, Yu Yuanzhen personally verifies the steadiness of his cultivation and sees his Golden Sacred Dragon and purple Second Soul Ring, dispelling his remaining doubts about the reported changes 1 16 19 91.
• Luo Sanpao — Martial Soul and cherished companion. Yu Xiaogang explicitly rejects the idea that its worth depends on successful evolution 19.
• Yu Luomian — Uncle. Joins the elders in examining Luo Sanpao’s changes and assuring Yu Xiaogang of the clan’s support. He is also Liu Erlong’s father, making her Yu Xiaogang’s paternal cousin 17 19 108.
• Dugu Bo — Fellow disciple of Li Qingshan, who recognizes Yu Xiaogang as his senior brother because he joined first despite being younger. Offers to accompany the next medicine-seeking expedition, but is instructed to remain in the city with Xin’er. Later supports the decision to seek Yu Xiaogang’s Third Soul Ring in the Star Dou Great Forest 39 48 113.
• Bibi Dong — Close companion and later fellow disciple. The two spend mornings together in Coconut Grove City, where she helps him devise Martial Soul control exercises and accompanies his Second Soul Ring absorption. Their affection is evident in his eagerness to meet her and her care for him and Luo Sanpao. Her letter about Qian Xunji’s mistreatment angers him; after Li Qingshan brings her to the clan, he is relieved to find her safe 68 69 70 71 92 103 112.
• Flender — Fellow disciple and partner in the Trinity Martial Soul Fusion Skill. They practice Soul Power coordination together and jointly ask Li Qingshan to accept Liu Erlong as a disciple 109 111 112.
• Liu Erlong — Paternal cousin, traveling companion, fellow disciple, and fusion-skill partner. Yu Xiaogang does not initially know her when they meet. He later praises her diligence and kindness while supporting her admission as Li Qingshan’s nominal disciple 108 109 111 112.
• Ning Fengzhi — Fellow disciple who addresses him as senior brother and praises his meticulous, intellectually honest explanations. Yu Xiaogang’s identity as Yu Yuanzhen’s son is formally introduced during discussions concerning an alliance with his clan 90 92.
• Ah Yin — Fellow member of the traveling group. Uses her Blue Silver Grass beside Yu Xiaogang and his companions while they recover after their first fusion-skill manifestation 68 112.
• Chen Jianjun — Senior traveling companion. Remains to guard Yu Xiaogang during Third Soul Ring absorption when Li Qingshan leaves to investigate an approaching fierce presence 114.
• Clan youths — Peers who resent his apprenticeship and mock his poor aptitude; he leaves without responding to their provocations 19.
