Background

Liu Erlong is the illegitimate daughter of Yu Luomian of the Blue Lightning Tyrant Dragon Clan and Yu Xiaogang's cousin. She was formerly one of the Golden Iron Triangle alongside Yu Xiaogang and Flender, serving as its renowned “Killing Horn”; their three-person Martial Soul Fusion Skill was the Golden Sacred Dragon. 191 215

She founded Blue Tyrant Academy after becoming disheartened with her past. Although she had once been obsessively devoted to Yu Xiaogang and even severed ties with her family for him, learning more about his conduct—and watching him disparage Lin Qingmo—left her emotionally numb and increasingly disgusted with him. 134 191

Foreseeing that Flender would bring Shrek Academy to Blue Tyrant Academy, Liu Erlong relinquished the acting deanship to him for three years. She framed this as repayment for Flender's earlier kindness, while using her departure to permanently avoid Yu Xiaogang and sever their ties. 213

She then traveled to Heaven Dou Royal Academy, partly drawn by her prolonged Chat Group contact with Lin Qingmo. She became the Imperial Fighting Team's leader, while Dugu Bo served as honorary team leader. 214 215

Liu Erlong is a mature woman with a fierce, athletic presence befitting her Fire Dragon Martial Soul.

• Often wears a fitted crimson combat outfit. 214
• Has long hair, typically tied back. 214
• Her brows and eyes are sharp and imposing, though she can present a composed, gentle demeanor around Lin Qingmo. 214 215

Personality

Liu Erlong is straightforward, proud, and intensely protective. Her temper is famously explosive; as the Imperial Fighting Team's instructor, she does not hesitate to discipline complacency or negligence. 4 281 328

Beneath her aggression, she is generous and deeply attentive to those she accepts as her own. She guarded the academy's Back Mountain throughout Lin Qingmo's seclusion, offered to accompany his fifth-ring hunt, funded his auction outing, and repeatedly worried about his safety during dangerous expeditions. 238 239 295 338

Her past attachment to Yu Xiaogang initially made her defensive whenever he was criticized. Over time, she confronted the disappointment and resentment she had suppressed for years, ultimately choosing to move on rather than remain bound to her former relationship. 4 213 372 373
