Background / History

Old Liu teaches Chen Ye’s cohort at Wu University. During the students’ introductions, he recognizes Chen Ye’s name and lets him sit down without revealing his hero codename, apparently aware that Chen Ye’s circumstances require discretion. 16

After spending twenty days in a Secret Realm, Old Liu returns noticeably thinner, aged, and haggard. Despite the toll of the experience, he immediately agrees to resume teaching when asked; his students have become an important source of emotional support for him. 58

He prepares students for successive Secret Realms by explaining monsters, entry rules, team-size limits, and the practical dangers of each scenario. Before Secret Realm 3, he has the six-person team train together so they can cooperate effectively. 81 83

During a monster ambush targeting Tang Zichen, Old Liu recognizes that the situation is abnormal and refuses to abandon Chen Ye and Tang Zichen after they leave the convoy to draw away the attackers. 104 105 He later learns that Chen Ye is the successful bearer of the supposedly unattainable S1 talent and apologizes for having previously underestimated him. 145

Appearance

Following his return from Secret Realm 2, Old Liu is described as having lost significant weight and looking aged and haggard, with the sharpness of his former bearing diminished. His mental state nevertheless remains positive, and he habitually smiles while teaching. 58

• Carries and maintains a saber. 165
• His neck remains visibly stiff after the monster attack surrounding Secret Realm 4. 110
• Appears stern and visibly troubled when students face dangerous Secret Realm assignments. 94 149

Personality

Old Liu is a responsible and practical teacher who prioritizes his students’ safety over pride or competition. He warns Tang Zichen not to risk herself against Level 6 experts merely for potential points, advises Shao Wenhui to forfeit when her combat awareness proves inadequate, and cautions Chen Ye’s team that foreign opponents in the Global Championship may not show restraint. 134 149 281

He is also humble enough to reevaluate his judgments. Once Chen Ye’s concealed strength becomes clear, Old Liu acknowledges his own shortsightedness, bows to Chen Ye, and accepts that Chen Ye’s choice to remain inconspicuous was necessary for survival. 145

Despite his caution, Old Liu is fiercely protective. During the Magic City monster crisis, guilt over not stopping Tang Zichen from reaching the battlefield drives him to attempt a suicidal charge against the monsters. 184

Abilities & Skills

Equipment / Weapons / Items

Relationships

• Chen Ye — Student. Old Liu initially misunderstands Chen Ye’s potential, later learns of his concealed S1 talent, apologizes, and continues to treat him as a student rather than excessively changing their relationship. 145
• Tang Zichen — Student and class monitor. Old Liu is deeply concerned by the danger surrounding her and tries to dissuade her from taking risks beyond her current level. 134
• Liu Yu — Niece. Old Liu is grateful to Chen Ye for the exceptional rewards Liu Yu receives and nearly has her kowtow in thanks. 245
• Zhao Zheng, Cao Yu, Ren Qianqian, and Shao Wenhui — Students whom Old Liu trains, advises, and protects through Secret Realm preparation and competition. 81 149 281
• Principal Lu — Fellow educator and adviser during the National Secret Realm and Global Championship. 147 150

Story Role / Major Arcs

Wu University Instructor

Old Liu serves as the primary instructor for Chen Ye’s class, overseeing introductions, strength tests, potential allocation, and Secret Realm preparation. He is especially proud of Tang Zichen’s early accomplishments and initially views her as the class’s likely champion. 16 23 93

Secret Realm 3 Preparation

He introduces the team-based rules of Secret Realm 3 and arranges joint training for Chen Ye’s six-person group before their move to Magic City. 81 83

Convoy Monster Ambush

Old Liu realizes that the unusually coordinated monster breach is likely a deliberate plot. He joins Chen Ye, Tang Zichen, and Teacher Jian after they leave the convoy rather than escaping with the remaining students. 104 105

Recognition of Chen Ye’s Strength

After Chen Ye’s power and S1 identity are revealed within the National Secret Realm, Old Liu admits his prior misjudgment and bows in apology. He supports Chen Ye’s decision to conceal his strength from the outside world. 145 149

Magic City Monster Crisis

Old Liu is astonished when Chen Ye annihilates airborne monsters with Fire Fist techniques. Later, overwhelmed by guilt over Tang Zichen’s involvement in the battlefield, he attempts to sacrifice himself before Long Aotian arrives and turns the battle. 181 184

National Secret Realm Revelation

During the later National Secret Realm, Old Liu witnesses Chen Ye’s overwhelming performance and finally realizes that the Divine Dragon is his own student. This clarifies for him why Tang Zichen had insisted on forming a team with Chen Ye. 281 294

Level 5 Breakthrough

After joining Chen Ye’s team, Old Liu reaches Level 5—an achievement he had considered impossible for himself—and openly thanks Chen Ye for helping him fulfill his lifelong dream. 304
