Background / History

Wu Changkong was once a gifted student of Shrek Academy. His education gave him extensive knowledge of martial souls, historical records, and unusual cultivation phenomena. Students at Eastsea Academy describe him as a former advanced-division teacher who was demoted to teaching intermediate-division freshmen, though their conversation does not establish the reason 28 33 37.

His deceased beloved, Long Bing, remains a deeply personal memory. When he first sees Tang Wulin’s azure-blue hair and sapphire eyes, he briefly imagines that a child he might have had with her would have looked similarly innocent. His normally icy expression softens for an instant before he conceals the emotion 28.

Appearance

• Hair: Long, lake-blue hair that falls like a waterfall 35.
• Eyes: Dark green, frequently described as clear, piercing, and icy 30 35.
• Build: Tall, with a 1.90-meter frame 29.
• Clothing: Often wears a plain, old-fashioned white robe; also appears in a simple white shirt and gray-black plaid trousers 28 29 35.
• Reputation: Students praise his looks and describe him as Eastsea Academy’s “cold, aloof heartthrob” 28.

Personality

Wu Changkong is aloof, proud, and uncompromising. He speaks tersely, dismisses empty reassurance, and expects even the academy’s lowest-ranked students to pursue exceptional strength. He rejects ridicule based on martial-soul quality, but is equally harsh toward gifted students who fail to match their advantages with effort and sound judgment 28 30.

His severity coexists with genuine protectiveness. He supports his students when they confront injustice and personally stands between them and a threatening Soul Emperor. In private, he respects Tang Wulin’s reluctance to disclose every detail of his dangerous power, choosing concern over further interrogation 34 35 37.

Abilities & Skills

Heavenly Frost Sword and Ultimate Ice

Wu Changkong’s martial soul is a pale-blue longsword with a clear blade and a cold, moonlike edge. His attacks combine swordsmanship with freezing soul power 35 53.

• Armor penetration: A single stroke tears scales from Guang Biao’s Ironclad Dragon-covered fist and forces the fellow Six-Ring Soul Emperor backward 35.
• Internal freezing: Sword energy enters Guang Biao’s meridians and slows the circulation of his soul power 35.
• Binding destruction: Cuts through Tang Wulin’s bloodline-reinforced Blue Silver Grass; an eruption of ultimate ice shatters a dense enclosure of vines 53.
• Soul-ring foundation: Possesses two ten-thousand-year rings, which visibly alarm Guang Biao during their confrontation 35.

Swordsmanship and Combat Control

Wu can overwhelm his students without relying on his martial soul’s full display. He defeats Xie Xie in one exchange and later suppresses all five Class Zero students together 30 53.

• Practice-weapon proficiency: Uses a flexible belt sword and a wooden sword in training 30 33.
• Attack redirection: Alters Gu Yue’s fireball trajectory with a small amount of soul power, sending it into Xie Xie 33.
• Precision strikes: Defeats Tang Wulin with a light punch that disrupts his balance rather than an overwhelming release of soul power 30.
• Controlled sparring: Adjusts punishment to students’ durability and avoids striking Tang Wulin’s face 53.
• Demonstrated limit of practice equipment: Tang Wulin’s full-strength hammer strike breaks his wooden sword, although Wu still wins the spar 33.

Teaching and Tactical Instruction

Wu personally teaches Class Five’s courses and later develops a specialized curriculum for Class Zero. He treats actual combat as essential preparation for every Soul Master, including those with tool martial souls 29 50.

Student	Training priority
Tang Wulin	Master his unusual Blue Silver Grass, improve his limited soul-power reserves, and use his advantages more effectively 30 32.
Xie Xie	Build physical endurance, improve combat judgment, and preserve his second martial soul as a decisive surprise 30 32.
Gu Yue	Develop combinations of elements to exploit her already advanced elemental control 32.
Wang Jinxi	Strengthen spiritual power to avoid future obstacles when fusing with soul spirits 54.
Zhang Yangzi	Continue developing spiritual power and aim to leave the Spirit Origin Realm within a year 54.

• Physical conditioning: Assigns weighted running; Tang Wulin and Xie Xie initially wear nearly ten kilograms of iron clothing 31.
• Team tactics: Trains Tang Wulin as controller, Xie Xie as agility attacker, and Gu Yue as the main offensive fighter 33.
• Technical education: Teaches mecha history, soul-guidance fundamentals, battle armor, soul-beast identification, and related professions 37 50 51 56.
• Battle-armor preparation: Explains that participating in equipment design, forging, or repair helps make battle armor a true extension of its wearer 51.

Assessment and Historical Knowledge

Wu combines direct testing with knowledge inherited from Shrek’s records. His observations often identify genuine abnormalities, although incomplete information can lead him to mistaken explanations 33 37 55.

• Suspects that Tang Wulin’s exceptional Blue Silver Grass might be a dormant Blue Silver Emperor 30 32.
• Considers martial-soul mutation or a hidden second martial soul after testing Tang Wulin’s strength and spiritual power 33.
• Accepts Tang Wulin’s cover story that the Golden Dragon is his second martial soul; he does not discover the concealed Clear Sky Hammer or the bloodline’s true nature 37 55.
• Interprets later changes as martial-soul awakening and fusion, while warning Tang Wulin to report any dangerous symptoms 55.
• Notices Tang Wulin’s resemblance to both Tang Wutong and Tang San 56.
• Recognizes the Disorder Splitting Wind Hammer during the Spirit Ascension Platform trial 57.

• Two-Word Battle Armor — Tang Wulin recalls that Wu possesses this equipment and estimates that wearing it could raise his combat strength beyond Soul Saint toward Soul Douluo. Its activation is not shown in the supplied passages 34.

Relationships

• Tang Wulin — Student and protected charge. Wu defends him against martial-soul prejudice, promises to conceal his third-rank blacksmith achievement, and monitors his dangerous physical changes 28 31 55.
• Xie Xie — Student whose twin martial souls and innate full soul power make Wu particularly critical of wasted potential. His instruction emphasizes stamina, judgment, and secrecy 30 32.
• Gu Yue — Admits her to Class Five after her assessment and recognizes her exceptional elemental control. Shows greater physical restraint toward her during sparring 32 53.
• Wang Jinxi — Class Zero student whom Wu warns about insufficient spiritual power 49 54.
• Zhang Yangzi — Class Zero student trained and assessed alongside the others 53 54.
• Long Bing — Deceased beloved whose memory briefly resurfaces when Wu meets Tang Wulin 28.
• Mu Chen — Fellow mentor and protector of Tang Wulin. They exchange respectful acknowledgment after the confrontation with Guang Biao 35.
• Ye Yingluo — Rejected admirer. Her resentment motivates her desire to defeat and publicly embarrass Wu through the Class Promotion Tournament 35 45.
• Long Hengxu — Academy administrator. Wu secures his approval for Gu Yue’s admission and later works alongside him during Spirit Ascension Platform training 32 56 57.
