Background / History

Yu Xiaogang is Yu Xiaoheng's younger twin brother and Yu Yuanzhen's son. Before the twins' awakening, the Blue Lightning Tyrant Dragon Clan considered him its future: he was praised as a prodigy, physically strong for his age, and expected to awaken the Blue Lightning Tyrant Dragon with Innate Full Soul Power. Yu Yuanzhen and the clan planned to concentrate their resources on him while leaving Xiaoheng to manage the clan's industries. 3 4 5 13

He looked down on Xiaoheng's commerce, physical training, and book learning, believing bloodline, martial soul, and innate soul power mattered above all else. Xiaoheng outperforming him in a knowledge assessment wounded his pride, especially when Liu Erlong defended Xiaoheng and pushed him away. Yu Xiaogang gave a reluctant apology, then vowed to prove himself at the Spirit Awakening. 1 2 5

His awakening instead produced Luo San Pao, a failed mutation. Unable to accept the result, he demanded repeated testing and publicly lost control; the clan and its guests regarded the display as disgraceful. Xiaoheng's subsequent successful awakening left Yu Xiaogang isolated and eclipsed. 15 19 20

After the awakening, his resentment initially deepened. He opposed Xiaoheng's early Thunder Pool body tempering, predicted his failure, and protested the use of thirty-six Jade Marrow Thunder Stones because three had once been reserved for his own future tempering. Yu Yuanzhen struck him and publicly rebuked his selfishness. 27 28 29

Yu Xiaogang gradually redirected his efforts toward theory, business management, secret cultivation, and martial soul evolution. Discovering that Xiaoheng's Golden Holy Dragon functioned as a Split Body Spirit led him to recognize that Luo San Pao might possess the same potential. He secretly manages Xiaoheng's commercial interests while using rare herbs and whale rubber to pursue evolution, naming his martial soul Luo Buhui. 31 35 62

After Yu Xiaoheng was presumed dead, Yu Xiaogang assumed a far greater share of the clan's administration and defense. He modeled his demeanor, training, resource use, and decision-making after his brother, eventually earning recognition from Yu Yuanzhen and the elders while continuing to resent being compared with him. 278 374 409 460

During the crisis surrounding the clan's destruction, he reunited with Yu Xiaoheng and accepted that the clan's survival outweighed their rivalry. He later obtained the Lovesick Heartbreak Red through his sincere feelings for Lin Wan'er, helped Yu Xiaoheng escape with the clan foundation, and remained behind to delay the enemy. 473 476 477

Appearance

Yu Xiaogang resembles Yu Xiaoheng closely as his twin, though his condition and presentation deteriorate after his failed awakening.

• Initially carries himself with proud, carefully arranged bearing as the clan's favored young master. 3 4
• Following his fall from grace, he is described with unkempt hair, disordered clothing, and visible footprints on his clothes. 27
• During his private research, he has bloodshot eyes, disheveled hair, and wrinkled clothes from long hours amid scrolls and account books. 62
• Often carries Luo San Pao in his arms and tries to conceal both himself and the spirit from public attention. 38
• His attempts to impersonate Yu Xiaoheng rely on their similar build, cosmetics, altered voice, and a layer of golden light produced by his Spirit Ring ability. 205
• Repeatedly overtaxing his body turns his hair deathly white and leaves him gaunt, weak, and prone to coughing blood. 461 473
• After using Lin Wan'er's sacrificial power, he develops purple-black eyes, an ominous aura, and a visibly deteriorating physical condition; at one point, he requires a specially made wheelchair. 488 524
• Following his later changes, he is frequently unshaven and carelessly dressed, with the former pride in his presentation largely gone. 565

Personality

Yu Xiaogang begins as arrogant, competitive, and deeply reliant on the status promised by his bloodline. He sees Xiaoheng's different path as inferior and interprets his brother's accomplishments as deliberate attempts to compete with or humiliate him. His jealousy is particularly evident around Liu Erlong, whom he wants to choose him over Xiaoheng. 3 5

His failed awakening exposes his inability to accept defeat. He publicly insists the awakening stone must be defective, becomes consumed by the loss of resources and recognition, and lashes out at Xiaoheng's body-tempering effort. 15 27 28 29

Later, he becomes more restrained and determined. Mockery no longer provokes him openly; instead, he studies, manages commerce, trains in secret, and pursues a path based on martial soul theory. This resolve is accompanied by growing ruthlessness: he concludes that surpassing Xiaoheng may require abandoning attachments and taking opportunities without hesitation. 35 62 71 72

His years living beneath Xiaoheng's legacy make him highly conscious of comparison and recognition. Although he successfully imitates his brother's composure and leadership, Xiaoheng's return initially fills him with fear and resentment because it threatens the identity he built in his brother's absence. 409 460

Yu Xiaogang is capable of genuine loyalty to the clan and attachment to those close to him, particularly Lin Wan'er and Yu Xiaoheng. However, his readiness to exploit Lin Wan'er's sacrifice for power reveals the extreme moral compromise produced by his desperation. Even while recognizing his guilt, he accepts the power and consequences of her death. 463 477 485 494

Abilities & Skills

Martial Soul Theory

Yu Xiaogang possesses substantial theoretical knowledge of martial souls and body tempering.

• Identifies the limits and risks of early body tempering from sect records. 29
• Deduces that the Golden Holy Dragon is a Split Body Spirit capable of consuming external objects to grow. 31
• Applies the same reasoning to Luo San Pao, seeing its abnormal nature as potential rather than proof of worthlessness. 31 35
• Searches ancient texts for a route to martial soul evolution. 71
• Studies the diminishing returns of Luo Buhui's Devour trait, determining that each further ten-level interval greatly raises the difficulty of cultivation. 278

Luo San Pao / Luo Buhui / Dark Dragon

His mutated martial soul is a detachable Split Body Spirit later renamed Luo Buhui and evolved into the Dark Dragon.

• Its initial emergence destroys Yu Xiaogang's standing as the clan's anticipated heir. 15 19
• Yu Xiaogang believes it can evolve by absorbing external objects, based on his Split Body Spirit theory. 31
• He prepares violent medicinal herbs for it despite its fearful reaction, seeking evolution by any necessary means. 62
• His desire to feed and evolve it drives his participation in the spirit-hunting expedition. 38
• Luo Buhui can devour herbs with conflicting properties and convert their power into pure Soul Power for Yu Xiaogang, though the process inflicts immense pain. 256
• Its Devour trait can forcibly raise Yu Xiaogang's Soul Power through external resources, granting explosive early growth but suffering severe diminishing returns after Level 20. 278
• After Lin Wan'er's sacrifice and curse, Luo Buhui evolves into a Dark Dragon associated with black mist, deathly aura, and Yu Xiaogang's destructive new power. 524 565

Commerce and Resource Management

After Xiaoheng shifts his focus to cultivation, Yu Xiaogang takes responsibility for the clan's commercial affairs.

• Directs sea-transported goods to be sold in batches, increasing profits by nearly ten percent. 62
• Uses access to commercial channels to intercept rare medicinal herbs for his personal cultivation. 71
• Bribes Soul Hunting Forest guards with goods from Xiaoheng's merchant caravan. 72
• Raises resource purchase prices and works through commercial rules to secure greater supplies for Xiaoheng's cultivation as well as his own. 62
• Later manages Heaven Dou City profits, clan logistics, defensive arrangements, intelligence gathering, and resource distribution during the clan's crisis. 278 360 460 452

Secret Cultivation

Yu Xiaogang pursues rapid, concealed improvement after recognizing the potential of his own path.

• Consumes large quantities of rare herbs, raising his Soul Power from Level 3 to Level 5 in half a month. 71
• Plans to refine excess medicinal energy through fighting low-level Soul Beasts in the Soul Hunting Forest. 71
• Hides his training from Yu Yuanzhen. 63
• Uses whale rubber, medicinal herbs, soul beast flesh and blood, and direct body tempering to strengthen his physique beyond its normal limits. 38 41 205
• Absorbs the power of a Jade Marrow Thunder Stone to imitate Xiaoheng's lightning-tempered presence, enduring pain without outward complaint. 205
• Continues consuming herbs even when their toxins and medicinal power damage his body, forcing his Soul Power close to Level 20. 256

Spirit Skills and Combat

Yu Xiaogang's late-stage combat ability is largely founded on Luo Buhui's evolution, Lin Wan'er's sacrificial power, and Void Ring.

• His First Spirit Ring ability can imitate the golden radiance and aura of Yu Xiaoheng's Dragon God Possession closely enough to deceive Ning Zhenyuan and Tang Wei when combined with disguise and a Jade Marrow Thunder Stone. 205
• Void Ring condenses surplus sacrificial power into temporary Spirit Rings, allowing him to wield strength far above his true Spirit King cultivation for a limited period. 485 514
• Dark Dragon Break allows him to clash directly with Jiu Yuan, a Titled Douluo, while in his temporary empowered state. 488
• His Martial Soul Avatar manifests as a Purple-Gold Dark Dragon, whose Dragon Breath overwhelms Jiu Yuan's Blood-Winged Demon Eagle Avatar. 489
• Fifth Soul Skill: Grievance Flame, Soul Lock traps and immobilizes Jiu Yuan as he attempts to flee. 489
• His temporary Titled Douluo pressure is sufficient to cripple a Spirit Saint in one strike and deter a coalition of thousands from entering the clan's ancestral grounds. 488 490
• Even after his borrowed power begins fading, he uses Luo Buhui and the reputation of the Evil Dragon Douluo to maintain the appearance of Titled Douluo-level deterrence. 497

Relationships

• Yu Xiaoheng — Elder twin brother and principal rival. Yu Xiaogang envies his recognition and resents his achievements, but studies Xiaoheng's persistence and follows his practical approach to resources and cultivation. Xiaoheng later asks Yu Yuanzhen to plan a suitable Spirit Ring for him. After Xiaoheng is presumed dead, Yu Xiaogang attempts to replace him; upon his return, Yu Xiaogang gradually chooses to support and protect him despite lingering jealousy. 5 27 35 94 409 473 477 538
• Yu Yuanzhen — Father and Sect Master. He once favored Yu Xiaogang as the clan's future, then becomes bitterly disappointed by his conduct after the failed awakening and Thunder Pool dispute. Yu Yuanzhen later recognizes his business ability, supports his impersonation of Xiaoheng, and grieves over the life force Yu Xiaogang sacrifices for the clan. 3 7 29 62 205 514
• Liu Erlong — Object of Yu Xiaogang's early desire and jealousy. Her loyalty to Xiaoheng, including physically defending him against Yu Xiaogang, intensifies his humiliation. In later years, Yu Xiaogang no longer pursues her and their relationship becomes more cooperative, with Liu Erlong assisting his clan work. 3 5 19 62 360
• Lin Wan'er — Yu Xiaogang's fiancée and closest emotional attachment in his later life. She supports his efforts for the clan and ultimately sacrifices herself to save him after he engineers a situation intended to obtain her power; her soul enters his sea of consciousness, while her curse and sacrificial power reshape his future. 374 461 485 514
• Luo San Pao / Luo Buhui / Dark Dragon — His Split Body Spirit and the focus of his efforts to reclaim strength and status. Its Devour trait drives his rapid growth, while its evolution into the Dark Dragon becomes the basis of his later combat power. 31 38 62 256 524
• Blue Lightning Tyrant Dragon Clan disciples — Once praised him as a prodigy, then ridicule and dismiss him after his awakening failure. He eventually learns to endure their scorn without outward anger and later earns their respect by managing the clan and defending its survivors. 4 20 35 374 490 494

Story Role / Major Arcs

Favored Heir and Brotherly Rivalry

Before the awakening, Yu Xiaogang is the clan's celebrated prospect and treats Xiaoheng as an inferior brother wasting his potential on trade and physical training. Xiaoheng's hidden knowledge and closeness with Liu Erlong trigger open conflict. 3 5

Failed Spirit Awakening

Yu Xiaogang awakens Luo San Pao rather than the Blue Lightning Tyrant Dragon. His public breakdown turns the clan's grand ceremony into a scandal, while Xiaoheng's awakening immediately replaces him as the focus of the sect's hopes. 15 19 20

Thunder Pool Opposition

Bitter over Xiaoheng's rise and the diversion of sect resources, Yu Xiaogang predicts his brother's failure and demands the return of Jade Marrow Thunder Stones promised for his own future use. His behavior earns Yu Yuanzhen's first physical punishment. 27 28 29

Theoretical Path and Secret Training

Yu Xiaogang reframes Luo San Pao as a Split Body Spirit with evolutionary potential. He manages business affairs, researches ancient texts, consumes rare herbs, undertakes secret training, and seeks combat in the Soul Hunting Forest to refine his unstable gains. 31 62 63 71 72

First Spirit Ring and Impersonation

After forcefully tempering his body and absorbing a mutated Dawnlight Scale Colt Spirit Ring, Yu Xiaogang gains an ability similar to Xiaoheng's Dragon God Possession. He uses cosmetics, altered speech, a Jade Marrow Thunder Stone, and Luo Buhui's transformed appearance to impersonate Xiaoheng and drive away the leaders of the Seven Treasures Glazed Tile Sect and Clear Sky Sect. 205

Acting Heir During Xiaoheng's Absence

Following reports of Xiaoheng's death, Yu Xiaogang takes charge of commercial affairs, intelligence, logistics, and clan defenses. He consciously copies Xiaoheng's composure and ruthlessness, gradually becoming a figure the elders can rely on, though the comparison to his supposedly dead brother continues to embitter him. 278 360 374 409 460

Reunion and Sunset Forest Mission

When Yu Xiaoheng is revealed to be alive, Yu Xiaogang is initially terrified and resentful, but accepts Yu Yuanzhen's order to support him in Sunset Forest. He reunites with Xiaoheng, reports the clan's dire condition, and receives the responsibility of helping preserve the clan foundation. 409 462 473 474

Lovesick Heartbreak Red and Rearguard Sacrifice

Yu Xiaogang successfully plucks the Lovesick Heartbreak Red through his genuine love for Lin Wan'er. He subsequently creates a diversion with Luo Buhui to draw away pursuers and buy Yu Xiaoheng time to escape with the clan's foundation. 476 477

Lin Wan'er's Sacrifice and Evil Dragon Power

During the fall of the Blue Lightning Tyrant Dragon Clan, Yu Xiaogang exploits Lin Wan'er's devotion to obtain her Hundred-Thousand-Year Soul Beast sacrifice. Her power and curse transform Luo Buhui into the Dark Dragon and enable Yu Xiaogang to use Void Ring to create temporary red Spirit Rings. 484 485 524

Defender of the Ancestral Grounds

Empowered to a temporary Titled Douluo state, Yu Xiaogang protects the clan's retreat, cripples a Spirit Saint, battles Jiu Yuan, and forces the allied army to withdraw in terror. Though his body is left close to collapse, he continues maintaining the facade of the Evil Dragon Douluo to deter further invasion. 488 489 490 497 514

Trivia

• Yu Xiaogang was originally expected to become the Blue Lightning Tyrant Dragon Clan's next Sect Master. 3 4

• Despite his hostility toward Xiaoheng, he consciously models his later persistence and resource-seeking after his elder brother's example. 28 35
• Yu Xiaogang renamed Luo San Pao to Luo Buhui, meaning that neither he nor his martial soul would live with regret over their pursuit of strength. 62
• He successfully plucks the Lovesick Heartbreak Red, an Immortal Herb that requires sincere, single-minded love and heart's blood. 476
• His temporary rise to Titled Douluo-level power is purchased with Lin Wan'er's sacrifice, the depletion of most of his life force, and a curse that continuously consumes his vitality. 485 514
