Background & History

Wu Changkong is a disciple of Shrek Academy’s Crimson Dragon Douluo, Zhuo Shi. Born with Innate Full Soul Power, he was considered a gifted soul master and had already reached the Soul Emperor realm six years before Zero Class was formed. His cultivation later stagnated at rank 69 following the death of his girlfriend, Long Bing, leaving him deeply melancholic and detached from his former self. 37 53 55

Before teaching Class One, Wu reviewed Eastsea City’s unusually exceptional student profiles. He was astonished by the concentration of talent in Jiang Yan, Gu Yuena, Xie Xie, Wei Xiaofeng, Zhang Yangzi, and Wang Jinxi, and resolved to bring them to Shrek Academy if they were willing. 34

He became Class One’s homeroom teacher and immediately recognized Jiang Yan as a rank 34 Soul Elder despite the boy being only nine years old. His first lesson centered on practical combat, culminating in Wu challenging Jiang Yan while restricting himself to Soul Elder-level soul power and his first three Soul Skills. 37 38 39

The spar exposed the immense disparity between them. Jiang Yan’s elemental superiority nullified Wu’s ice-based techniques, caught the Skyfrost Sword barehanded, and sent Wu flying with a Flame Fist that pierced Sky Ice. Although shaken by the defeat, Wu accepted Jiang Yan’s offer to arrange repairs but chose to handle the armor himself. 39 40 41 43

When Eastsea Academy considered replacing him after Jiang Yan surpassed him, Jiang Yan argued that Wu’s strength and teaching style still made him well suited to practical training. Wu consequently remained with the students as Zero Class’s assistant homeroom teacher after Lu Li became the primary teacher. 53 54 55

Lu Li’s rank 81 cultivation forced Wu to confront how far he had fallen behind his peers. He resolved to work toward becoming a Titled Douluo and later continued assisting Zero Class with combat instruction and the Spirit Ascension Platform assessment. 55 56 68

Appearance

Wu Changkong is a tall, imposing man with an austere presence, standing over 1.9 meters tall. His appearance and demeanor are defined by coldness and restraint. 37

• Icy blue hair.
• Excellent physique and tall stature.
• A face described as cold as severe ice.
• Commonly wears white clothing while teaching. 37 53

Personality

Wu Changkong is aloof, reserved, and deeply affected by Long Bing’s death. His devotion to his late girlfriend became a defining part of his identity, while his resulting melancholy contributed to his stalled cultivation and detached attitude toward work. 37 55

As a teacher, he favors direct assessment through real combat and is able to recognize exceptional potential without dismissing students who need guidance. He is candid when criticizing poor judgment, as shown by his harsh reprimand of Tang Wulin’s jealousy and recklessness after the Spirit Ascension Platform trial. 38 68

Despite his pride being wounded by Jiang Yan and Lu Li, Wu does not deny reality. He acknowledges stronger people, accepts his limitations, and renews his determination to improve. 43 55 56
