Background and History

Clan Background

Yu Xiaogang is the eldest son of Yu Yuanzhen, master of the Blue Lightning Tyrant Dragon Clan. Despite his direct lineage and pure Yu-family bloodline, his Martial Soul mutates backward into a pig-like form. Gui Mei's investigation confirms that the mutation is genuine rather than a disguise for hidden talent 7 9 17 33.

His poor cultivation makes him an object of contempt within the clan. He recalls humiliation from his clansmen and beatings from his elders, developing an intense desire to escape his reputation as a failure 17.

Original Life

In the original course of events described by Lu Jin, Bibi Dong falls in love with Yu Xiaogang and wants to leave Spirit Hall with him. He gains access to Spirit Hall's library and uses its accumulated research to build his reputation as a theorist. Lu Jin characterizes his celebrated theories as appropriated knowledge mixed with personal conjecture 7 24.

Yu Xiaogang later stays at Nuoding Academy, where he recognizes that Tang San possesses Twin Martial Souls and becomes his teacher. He compiles the Ten Core Competencies and becomes a renowned Grandmaster. Lu Jin nevertheless criticizes his guidance, particularly his insistence on developing Blue Silver Grass along the control path 23 27.

His memories of this life include relationships with Bibi Dong and Liu Erlong, as well as Tang San's eventual godhood. He remembers growing old and dying while his disciple continued living as a god, a contrast that fuels his determination to pursue godhood himself 18 26.

Attempt to Meet Bibi Dong

A voice in Yu Xiaogang's head tells him that Spirit Hall's Holy Maiden is his destined partner and the key to changing his fortunes. Believing its predictions, he leaves his clan and heads toward Spirit Hall despite the danger 16.

At the gates, he declares himself the foremost authority on Soul Master theory and demands to see Bibi Dong. When the guards refuse, he claims to be her sweetheart and Spirit Hall's future Pope. The confrontation escalates into a public disturbance, and the guards beat him 17.

Qian Daoliu suspects that someone is guiding Yu Xiaogang and considers him a threat to Bibi Dong's future. He kills him with Soul Power despite a clansman's plea for mercy. While his body is being transported home, Yu Xiaogang revives and announces that he has been reborn 17.

Marriage Arrangement and Dugu Bo

After his revival, Yu Xiaogang seeks the Immortal Herbs at the Ice and Fire Yin Yang Well. Knowing that poisonous miasma surrounds the site, he decides to approach the future Poison Douluo, Dugu Bo, for access 18.

Meanwhile, Yu Yuanzhen and Tang Wei arrange a marriage between him and Tang Yuehua to strengthen cooperation between their sects against Spirit Hall. Yu Xiaogang objects, disparages Yuehua's inability to cultivate, and demands that she become a concubine because he intends to make Bibi Dong his lawful wife 19.

Outside Heaven Dou Royal Academy, he publicly offers to cure Dugu Bo's poisoning, hoping the achievement will restore his reputation and reach Bibi Dong's ears. Dugu Bo briefly poisons him to expose his inability to treat himself. Yu Xiaogang then reveals knowledge of Dugu Bo's secret medicinal garden 21.

The encounter ends when Yu Xiaogang suddenly attempts a sexual act with Dugu Bo's family's dog. Dugu Bo kills him, but his severed thread of fate reconnects. He revives during the return journey, discovers that he has reached level 30, and secretly escapes his escorts 21 22.

Search for the Ice and Fire Yin Yang Well

Yu Xiaogang acquires his third Soul Ring and enters Sunset Forest, increasingly convinced that resurrection proves he is the world's chosen protagonist. Unknown to him, Lu Jin is directing events so that Bo Saixi can use him to scout the dangers surrounding the Ice and Fire Yin Yang Well 22 25.

A five-hundred-year boar-type Soul Beast kills him in the forest. His body recovers, and he revives in less than an hour, but the memory of being impaled leaves him trembling at nearby movement 25.

Bo Saixi subsequently strikes him away from the well, inflicting fatal internal injuries. After another revival, he abandons his immediate attempt to obtain the herbs and decides to find Liu Erlong and Flender, hoping to recreate the Golden Iron Triangle 26.

Pursuit of Liu Erlong

Yu Xiaogang approaches Liu Erlong with knowledge of their potential three-person Martial Soul fusion skill. She rejects both his proposal and his romantic advances. After he persists outside her home, she kicks him hard enough to kill him 27 28.

His next resurrection takes noticeably longer because Lu Jin has altered his thread of fate. He then steals flowers to court Liu Erlong, but she condemns the theft and attacks him again. Treating rejection as an obstacle to overcome, he decides to obtain an aphrodisiac and sexually assault her, believing this will secure her cooperation 28 29.

At the black market, Yu Xiaogang takes goods without payment and insults its proprietor, Madam Cube. She has him poisoned, restrained, and subjected to sexual abuse. He eventually dies in captivity and is discarded into a sewer, where he revives the following morning 29 30 31.

Still blaming Liu Erlong, he returns with concealed aphrodisiac powder. An initial approach ends when a discarded Soul Tool strikes him and knocks him into a pond. Later, while attempting to drug her water vat, he swallows the remaining powder himself after she startles him 31 32.

Liu Erlong recognizes his intentions and kicks him away. Yu Luomian arrives, identifies him as her cousin, and discovers the attempted drugging. Yu Xiaogang openly threatens to try again, but Yu Luomian binds him and takes him back to the clan 32 33.

Forced Return

Yu Xiaogang does not expose Liu Erlong's parentage to Yu Yuanzhen, judging that revealing Yu Luomian's secret would worsen his own situation. Yu Yuanzhen interprets his behavior as an inappropriate preoccupation with women and continues pursuing the marriage agreement with the Clear Sky Sect, unaware that Tang Yuehua has disappeared 34.

Appearance

• Hair: Repeatedly described as having a buzz cut, cropped haircut, or crew cut 17 19 27.
• Injuries: Loses two molars during the confrontation at Spirit Hall and later a front tooth while obtaining stolen flowers. The missing front tooth makes his speech whistle 17 28 29.
• Liu Erlong's impression: She finds him unattractive, sharply contradicting his confidence in his own charm 27 28.

Personality

Yu Xiaogang is intensely proud of his supposed intellectual superiority. He introduces himself as Grandmaster before establishing a reputation in the altered timeline and expects guards, merchants, and other Soul Masters to defer to his theories. Public ridicule readily turns his confidence into anger and threats 17 21 29.

Repeated resurrection reinforces his belief that he is destined to become the protagonist and strongest god. He treats future opportunities, powerful allies, and romantic partners as things that rightfully belong to him, even when the altered timeline no longer follows his memories 22 25 26.

His pursuit of women is possessive and instrumental. He sees Bibi Dong as a route to advancement, dismisses Tang Yuehua as unworthy, and seeks Liu Erlong's strength through a fusion skill. When Liu Erlong refuses him, he shifts from courtship to attempted drugging and revenge, blaming her for the abuse he suffers elsewhere 16 19 26 29 30.

His bravado does not remove his fear of pain. Memories of violent deaths provoke panic, and prolonged captivity nearly breaks his will. Even when he later claims to have become indifferent to suffering, his resurrections preserve the experiences that torment him 25 26 31 32.

Abilities and Skills

Resurrection and Worldline Correction

Yu Xiaogang repeatedly returns from death because the world attempts to preserve his role in its intended future. Lu Jin explicitly explains that he cannot die permanently at this point in the story 23.

• Restores him after fatal Soul Power attacks, poisoning, Soul Beast attacks, and physical trauma 17 21 25 26 28.
• Preserves his memories; Yu Xiaogang experiences the process as his future self inheriting his body 25.
• Does not erase remembered pain or psychological trauma 26 28 31.
• Does not reliably restore every bodily function: he remains impotent after reviving from captivity 31.
• Can be affected by fate manipulation. Lu Jin's changes slow his revival after Liu Erlong kills him 28.

Memories of the Original Timeline

His reborn memories provide knowledge of people, resources, and relationships that have not yet developed in the altered timeline 18 26 27.

• Knows the location and value of the Ice and Fire Yin Yang Well and its Immortal Herbs 18 25.
• Knows about Dugu Bo's poisoning and secret medicinal garden 21.
• Remembers Liu Erlong's preferences and the Golden Iron Triangle's fusion potential 26 28.
• Frequently mistakes remembered events for guaranteed outcomes, leaving him unprepared for rejection or interference 19 27 28.

Luo Sanpao

Luo Sanpao is his reverse-mutated Martial Soul. In Lu Jin's account of Tang San's original first Soul Ring hunt, its demonstrated attacks rely on flatulence and fail to stop the Mandala Snake 7 27.

• Yu Xiaogang attempts to confuse the snake with the sound of Luo Sanpao's attacks 27.
• He is poisoned during the encounter and survives because Tang San treats him 27.
• His altered-timeline third Soul Ring is documented, but its associated ability is not described 25.

Soul Master Theory

Yu Xiaogang possesses solid basic knowledge, but Lu Jin disputes the originality and quality of his advanced theories 23 24.

• Recognizes Tang San's Twin Martial Souls in the original timeline 23.
• Compiles the Ten Core Competencies, which establish his original reputation 23.
• Draws heavily on Spirit Hall's accumulated library knowledge 24.
• Recommends the control path and Entanglement for Blue Silver Grass; Lu Jin and Ah Yin criticize these choices as neglecting its natural vitality and existing entangling ability 23 27.
• Initially proposes a ten-year Lone Bamboo for Tang San's first Soul Ring, based on his belief that Blue Silver Grass needs additional toughness 27.

Golden Iron Triangle Fusion

Yu Xiaogang knows that he, Liu Erlong, and Flender can combine their Martial Souls to summon the Golden Sacred Dragon 26 27.

• He seeks the fusion as a means of gaining enough strength to advance his plans 26.
• It is not performed in the documented altered-timeline events.
• Liu Erlong refuses to participate; the required harmony of hearts and minds is absent 27.

Relationships

• Yu Yuanzhen — Father and clan master. Arranges his marriage to Tang Yuehua, condemns his public scandals, and orders him brought home 19 26 34.
• Yu Luomian — Uncle and Liu Erlong's father. Discovers his attempted drugging of Liu Erlong and forcibly returns him to the clan 31 32 33.
• Bibi Dong — Original-timeline lover and intended lawful wife in his reborn plans. His attempt to claim a relationship with her leads to his first documented death 7 17 19.
• Tang San — Disciple in the original timeline. Helps him reach level 93, but becomes an object of resentment because he attains godhood while Yu Xiaogang eventually dies 18 24.
• Tang Yuehua — Intended political marriage partner. He demands concubine status for her; she later escapes the arrangement through Lu Jin 19 21.
• Liu Erlong — Cousin and remembered lover. In the altered timeline, she rejects him and becomes the target of his attempted sexual assault 26 27 32 33.
• Flender — Remembered partner in the Golden Iron Triangle; Yu Xiaogang intends to reunite with him and Liu Erlong 26.
• Lu Jin — Hidden manipulator of his fate. Studies his resurrections, uses him to scout Sunset Forest, and severs his destined romantic connection with Liu Erlong 20 22 26.
• Qian Daoliu — Kills him to prevent him from approaching Bibi Dong 17.
• Dugu Bo — Prospective source of access to the medicinal garden; kills him outside Heaven Dou Royal Academy 18 21.
• Bo Saixi — Secretly follows him as he scouts Sunset Forest, then drives him away from the Ice and Fire Yin Yang Well 25 26.
• Madam Cube — Black-market proprietor who imprisons and abuses him after he takes goods without paying and insults her 29 30 31.

Notable Quotes

Trivia

• “Yu Xiaogang could fly” is a recurring joke about him being struck or kicked through the air, not a flight ability 27 28.
• Lu Jin discovers that the world preserves Yu Xiaogang's survival while allowing substantial changes to his relationships and behavior, prompting further experiments with his thread of fate 23 26.
