Background

Yu Xiaogang is the son of Yu Yuanzhen, leader of the Blue Lightning Tyrant Dragon Clan, but is described as a discarded or expelled member of that clan. His weak cultivation, mutated Luo Sanpao Martial Soul, and lack of standing leave him deeply sensitive to contempt from others. 1 16 26

After Bibi Dong became Spirit Hall’s Holy Maiden, Yu developed a close relationship with her. Bibi initially admired his claimed martial soul knowledge and developed unusual feelings for him, though she was not ready to accept his attempt at physical intimacy. 1 2

Yu secretly bribed Bibi Dong’s maid, Xiaoming, to deliver messages and repeatedly praise him before Bibi Dong. This manipulation helped shape her early favorable opinion of him, but was later exposed by Ling Jing and admitted by the maid. 13 14

Appearance

Yu Xiaogang is described as an ordinary-looking young man. His lack of exceptional appearance is repeatedly contrasted with Bibi Dong’s status and talent. 1 16

• Has an ordinary build and appearance. 24
• Is around seventeen during his early visits to Pope’s Hall; by the Heaven Dou confrontation, he is described as twenty. 6 27
• His Luo Sanpao Martial Soul resembles a pale-purple, pig-sized dog with short limbs, a broad waist, and a rounded bulge on its head. 27

Personality

Yu Xiaogang is insecure, prideful, and intensely concerned with how Bibi Dong and others perceive him. Public disdain over his low talent and failures in martial soul theory repeatedly provokes resentment, particularly toward Ling Jing. 1 2 6

He tends to blame others for the consequences of his own actions. After Bibi Dong rejects him, he attributes the collapse of their relationship to Ling Jing rather than acknowledging his false claims, manipulation of Xiaoming, or misuse of Bibi Dong’s name. 15 16 25

His desperation also makes him manipulative and dishonest. When short of money in Spirit City, he uses his past association with Bibi Dong to obtain food, drink, payments, and admiration from inexperienced soul masters. 17

Abilities & Skills

Luo Sanpao

Yu Xiaogang’s Martial Soul is Luo Sanpao, a mutated beast Martial Soul that manifests as an independent pig-dog-like creature rather than possessing Yu directly. 27

• Summons two yellow Soul Rings, confirming his two-ring Soul Grandmaster cultivation. 27
• Luo Sanpao is intimidated by Ling Jing’s copied Seraphim Martial Soul and cannot effectively challenge its divine aura. 27
• Yu attempts to order Luo Sanpao to attack Ling Jing, but Ling Jing closes the distance before it can use its foul-smelling attack. 27
• His low Soul Power and poor combat performance leave him unable to defeat the nine-year-old Ling Jing. 26 27

Martial Soul Theory

Yu presents himself as an expert on martial souls and cultivation paths, using the title “Master” while offering appraisals and guidance. 2 17

• Incorrectly identifies Ling Jing’s Martial Soul as an Ice-Pattern Mirror Beast; a red-robed bishop publicly refutes him because it lacks the species’ defining ice patterns. 2
• Misunderstands the Mirror Beast Emperor’s development, recommending conventional assault, agility, or control paths instead of focusing on its replication ability. 6 7
• Claims that a second Soul Ring cannot exceed 764 years, a belief disproven by Ling Jing’s millennium second Soul Ring. 27
• Charges young soul masters for martial soul appraisals and cultivation advice while falsely implying that Bibi Dong endorsed his theories. 17

Equipment

• Twenty-Four Bridges Bright Moon Night — A rare Storage Soul Tool belt with twenty-four cubic meters of storage space. Yu acquired it cheaply from a pile of miscellaneous goods and intended to give it to Bibi Dong to restore their relationship. 14 15
  • Bibi Dong refuses the gift while ending their relationship. 15
  • Yu later surrenders it to compensate victims of his fraud; it is eventually recovered and given to Ling Jing. 18

Relationships

• Bibi Dong — Former romantic interest. Bibi initially admires Yu’s supposed knowledge, but his theoretical failures, bribery of Xiaoming, aggression toward Ling Jing, and fraudulent use of her name lead her to sever all ties with him. 2 14 16 25
• Ling Jing — Rival and target of Yu’s jealousy. Ling Jing exposes Yu’s errors and fraud, then defeats him in their public duel. 2 16 25 27
• Xiaoming — Bibi Dong’s former maid, whom Yu bribed to pass along messages and praise him to Bibi Dong. 13 14
• Flender — Meets Yu after his expulsion from Spirit City. Flender initially considers befriending him, but distances himself after learning about Yu’s deception. 18 25
• Liu Erlong — His cousin through the Blue Lightning Tyrant Dragon Clan. She is shocked to learn their relation but does not intervene when Spirit Hall confronts him. 26 28
• Yu Yuanzhen — Father and leader of the Blue Lightning Tyrant Dragon Clan. Yu invokes his father’s name to threaten Spirit Hall despite having been cast out by the clan. 1 26

Story Role / Major Arcs

Decline at the Spirit Hall Orphanage

During Ling Jing’s awakening ceremony, Yu’s poor Innate Soul Power is unfavorably contrasted with that of the orphaned children. He then damages Bibi Dong’s confidence in his scholarship by confidently misidentifying Ling Jing’s Martial Soul. 1 2

Loss of Bibi Dong’s Trust

Yu attempts to regain Bibi Dong’s favor through expensive meals, theoretical advice, and the Twenty-Four Bridges Bright Moon Night. His advice proves shallow, while the discovery that he bribed Xiaoming destroys Bibi Dong’s remaining trust. 6 7 13 15

When Bibi Dong rejects his gift and ends their relationship, Yu tries to attack Ling Jing. Bibi Dong shields Ling Jing and orders Yu never to seek her out again. 15 16

Fraud and Expulsion from Spirit City

Unable to support himself after the breakup, Yu exploits his former association with Bibi Dong. He poses as her trusted acquaintance, accepts money for guidance, and permits others to call him “Master.” 17

A Spirit Hall deacon publicly exposes him with Bibi Dong’s official order stating that he has no relationship with the Holy Maiden. Yu is beaten, expelled from Spirit City, permanently banned from returning, and forced to surrender his Storage Soul Tool as repayment. 17 18

Heaven Dou Confrontation and Defeat

Yu later encounters Bibi Dong, Ling Jing, Flender, and Liu Erlong in Heaven Dou Imperial City. Ling Jing publicly reveals Yu’s fraud and mocks his failed claims of martial soul expertise, while Bibi Dong confirms that their friendship is over. 24 25

After Yu insults Spirit Hall and invokes his clan background, Golden Crocodile Douluo offers him a chance to avoid punishment by defeating Ling Jing. Yu accepts, believing that his Soul Grandmaster cultivation will be sufficient. 26

Ling Jing defeats him with a single strike from the Angel Sacred Sword, inflicting a severe injury that leaves Yu physically and psychologically devastated. He is abandoned after Spirit Hall departs, though the Heaven Dou Imperial Family later rescues and treats him. 27 28 36

Trivia

• Yu’s incorrect identification of Ling Jing’s Martial Soul as an Ice-Pattern Mirror Beast later becomes especially embarrassing when Qian Daoliu recommends that species as a potential Soul Ring target. 7
• He calls himself a “Master” before gaining any demonstrated practical success as a martial soul theorist. 17 25
• His attempt to give Bibi Dong the Twenty-Four Bridges Bright Moon Night fails, and the belt ultimately ends up with Ling Jing instead. 15 18
