Liu Erlong

Biodata

Power Progression

Background

Liu Erlong belongs to the Blue Lightning Tyrant Dragon Clan but uses her mother’s surname, Liu. Her relationship with the clan is strained, particularly with her father, Yu Luomian, whom she barely acknowledges as a parent 44 48.

In her youth, she traveled and fought alongside Yu Xiaogang and Flender as the Golden Iron Triangle. Both men courted her, and she became romantically involved with Yu Xiaogang. Within the trio, she was known as the Horn of Slaughter 30 33 109.

After separating from Yu Xiaogang for more than a decade, she remained in Heaven Dou City and successfully ran Blue Tyrant Academy with support from the Blue Lightning Tyrant Dragon Clan. Her residence on the academy’s Back Mountain included a garden of flowers associated with their earlier relationship 11 12.

Appearance

Liu Erlong initially appears as a mature, youthful-looking woman whose appearance has changed little during her long separation from Yu Xiaogang 12.

• Clothing and hair: Introduced in a long blue-green dress, with her long hair loosely pinned behind her head 12.
• Apparent age before her breakthrough: Looks barely past thirty when she introduces herself to Shrek Academy’s teachers 34.
• Rejuvenation: After reaching level 90, her skin becomes fair and firm, her eyes clear, and her appearance resembles that of a woman in her early twenties 92.
• Combat appearance: Martial Soul Possession produces crimson dragon scales along her arms and scorching True Body Armor over her body 113.

Personality

Liu Erlong is outspoken, quick-tempered, and fiercely protective of those close to her. She beats clan members who insult her and Yu Xiaogang, confronts Shi Nian for attacking her students, and refuses to be intimidated by threats from Star Luo nobility. Although life beside Yu Xiaogang has softened her temper, it has not erased the ruthlessness behind her former title 44 65 96 109.

With Yu Xiaogang, she is affectionate, playful, and emotionally vulnerable. Their long separation leaves her afraid that he will disappear again, prompting her to accompany him to Nuoding rather than let him travel alone. She also shows practical affection through cooking and maintaining the garden that preserves memories of their youth 12 13 19.

Her treatment of younger characters is warm and encouraging. She comforts Ning Rongrong while urging her to learn from her mistakes, cares for Xiao Wu as her godmother, and accepts Zi Yan despite learning that she is a soul beast in human form. She regards Zi Yan as a child and Yu Xiaogang’s disciple rather than a threat 32 33 62.

Story Role / Major Arcs

Reunion and Return to Nuoding

Yu Xiaogang sends an unsigned letter containing a song from their youth. Recognizing it, Liu Erlong rushes to the academy gates and embraces him. He apologizes for their separation and promises not to leave again. In her garden, he recognizes the irises she planted as a symbol of longing 12.

After reconnecting in Heaven Dou City and accompanying him to the Ice and Fire Yin Yang Well, she insists on traveling with him to Nuoding. There, they reunite with Liu Bai, and Yu Xiaogang introduces her to Tang San and Xiao Wu as his wife 13 15 19.

Golden Iron Triangle Reunion and Academy Merger

Liu Erlong accompanies Yu Xiaogang to Shrek Academy, where they comfort Ning Rongrong and reunite with Flender. Their arrival brings the Golden Iron Triangle together again 31 32 33.

She subsequently agrees to incorporate Shrek Academy into Blue Tyrant Academy. Flender becomes vice dean, the teachers receive new positions, and the students move into Blue Tyrant’s dormitories 36.

Return to the Blue Lightning Tyrant Dragon Clan

Returning to the clan after a long absence, Liu Erlong beats Yu Xi, Yu Yansheng, and Yu Mifen for insulting her and Yu Xiaogang. At the clan gathering, her revealed Soul Douluo strength shocks the assembled members and prompts Yu Luomian to offer her an elder position 44 47.

The couple chooses not to remain. Their academy responsibilities draw them back to Heaven Dou City, while the clan’s arrogance and rigid attitudes leave neither comfortable staying there 47 48.

Tournament Protection and Reconciliation with Bibi Dong

During the academy tournament, Liu Erlong confronts Shi Nian after his spiritual attack on Blue Tyrant’s students. Releasing her eight Soul Rings, she drives him backward and only restrains herself when Yu Xiaogang intervenes 65.

After Bibi Dong helps protect Dai Mubai from the Evil-Eyed Saint King, Liu Erlong acknowledges her actions and agrees that they will not quarrel over Yu Xiaogang. A shared night-market outing turns their guarded relationship into a sisterly friendship 89 90.

Star Luo Threats and Fallen Soul Masters

When Dai Tian’s scheme against Zhu Zhuqing and Dai Mubai is exposed, Liu Erlong pins him down and suppresses his soul power so completely that he cannot summon his Martial Soul. Her Titled Douluo strength overturns his preparations, which were based on outdated information about the Golden Iron Triangle 108.

During a later convoy ambush, she rescues a wounded Soul Saint commander and fights the rank 95 Soul-Devouring Demon Shadow Soul Master. After breaking his arm, she meets his avatar with her own Fire Dragon Avatar and defeats him decisively. Yu Xiaogang then entrusts her with the other captured attacker as well 113 114.
