Background

Liu Erlong is a member of the Blue Lightning Tyrant Dragon Family who lives outside the clan as the dean of Blue Tyrant Academy. Yu Tiancheng, a collateral-branch disciple whose parents died early, intends to seek her out because she is one of the few relatives he considers loyal and dependable 1 2.

A copy of Yu Tiancheng's diary appears in her office shortly after he awakens the God-tier Time Dragon Martial Soul. Through it, she learns of his circumstances, his claimed knowledge of future events, and the predicted Soul Hunting Plan against the Upper Three Sects. Though initially skeptical, she becomes determined to protect both Tiancheng and the Blue Lightning Tyrant Dragon Family 2.

Her diary readership grants her a Soul Power increase and a Thousand-Year Left Arm Soul Bone, Power of the Red Dragon. The reward strengthens her resolve to grow stronger for Tiancheng and Blue Tyrant Academy 4.

Appearance

Liu Erlong is a tall, agile woman with a striking, forceful presence. Her fiery red hair and crimson Soul Power make her especially recognizable in battle 12 27.

• Long fiery red hair, described as cascading like flames down her back 27.
• Usually wears sharp black clothing; switches to a fitted dark-red hunting outfit for forest expeditions 27 43.
• Her battle attire and high-tied hair emphasize a fierce, practical appearance 43.
• Manifests crimson flames, a Red Dragon phantom, and Flame Dragon Wings when using her power 27 85.

Personality

Liu Erlong is intensely protective of Yu Tiancheng. His diary entries about crossing the Star Dou Great Forest alone leave her anxious and angry; she abandons her dean's duties to search for him personally, blaming herself for allowing him to face danger without support 7 12.

Her sternness comes from care rather than cruelty. After finding Tiancheng, she scolds him for his recklessness, forbids him from entering Sunset Forest alone, and offers to personally spar with him every day instead 12 40. Even when Tiancheng initially recoils from her touch, she responds with confusion and hurt before returning her attention to his injuries and safety 27.

As dean, she is cautious toward outside factions and unwilling to bind Blue Tyrant Academy to the Heaven Dou royal family without considering the consequences. She nevertheless respects Tiancheng's judgment and treats him as a trusted participant in the academy's decisions 69 70.

Story Role / Major Arcs

Diary Reader and Search for Yu Tiancheng

She eventually finds Tiancheng exhausted in a cave, guards him while he recovers, and flies him safely out of the forest before bringing him to Blue Tyrant Academy 27 29.

Blue Tyrant Academy

As dean, Liu Erlong gives Tiancheng a quiet courtyard near her own residence and oversees his entry into the academy 29. She watches his spar with Tailong, recognizes his combat judgment, and considers providing further training 32 33.

She later manages Blue Tyrant Academy's tense encounters with Shrek Academy, Martial Soul Hall exchange students, and Crown Prince Xue Qinghe's proposal to support the academy in the Elite Tournament 58 69 70.

Conflict with Yu Luomian's Faction

After Tiancheng returns to the clan, she gives him the Red Dragon Pendant as a safeguard. She later appears outside the Dragon Blood Secret Realm to protect him from Second Elder Yu Mingfeng and once again shields him from Yu Luomian's killing intent 88 104 105.
