Background / History

Mu En guarded Shrek Academy for centuries as its foremost deterrent and the Master of Sea God Pavilion. His existence as a Rank 99 Limit Douluo was central to Shrek’s ability to intimidate rival factions across the continent. By the beginning of the Holy Spirit Cult’s campaign, however, his health had deteriorated to the final stage of his life. He nevertheless continued personally guiding Shrek’s younger generation, including Huo Yuhao. 7 10 13

He was once a close friend of Long Xiaoyao and Ye Xishui. Their past entanglements complicated his response when he learned that Long Wushang—who led the attack on Shrek—was their son. 15 16

Appearance

In his final years, Mu En appeared as a frail elderly man with a pale complexion, white hair, and a habitual recliner in Sea God Pavilion. When he fought, he could restore his posture through borrowed life force and assume the form of the enormous Light Sacred Dragon. 13 15 17

• Aged, visibly weakened body during peacetime. 13
• White hair that billowed behind him after he forcibly revived his depleted vitality. 17
• Golden dragon scales and a massive Light Sacred Dragon form in battle. 15 22
• His body ultimately dissolved, leaving only a loose white robe behind. 28

Personality

Mu En was patient and gentle toward Shrek’s students, offering Huo Yuhao guidance not only in cultivation but in understanding martial souls and the wider continent. 13

As Shrek’s protector, he was pragmatic enough to make cruel judgments for the academy’s safety. When Long Wushang challenged him, Mu En could not deny that he might have eliminated a young Wushang if the latter lacked Long Xiaoyao and Ye Xishui’s protection, fearing the threat posed by the Original Sin Demon Puppet. 16

His final actions reflected a protective, reform-minded outlook. Rather than preserve Shrek’s prestige at all costs, he urged its leaders to prioritize the lives of children and adapt to the threat posed by soul tools. 27 28

Mu En also valued breadth of judgment in leadership. His earlier assessment that Yan Shaozhe was overly straightforward and lacked sufficient perspective to handle major matters later became a lesson Xuan Zi relied upon while guiding Shrek after Mu En’s death. 133

Abilities & Skills

Light Sacred Dragon Martial Soul

Mu En possessed the Light Sacred Dragon martial soul and could transform into an enormous golden dragon to defend Shrek City and confront Long Xiaoyao’s Dark Sacred Dragon. 13 15

• Created a golden curtain of light over Shrek City to shield it from enemy bombardment. 15
• Drew on the Golden Ancient Tree’s life force to temporarily restore his decayed body and combat strength. 15 17
• Used his ninth soul skill to briefly restrain Long Xiaoyao before rescuing Huo Yuhao. 22
• His light barrier purified evil soul masters and stabilized the injuries of Shrek’s defenders after Sea God’s Light was activated. 24

Dragon Core

Mu En nurtured a dragon core over centuries of cultivation. It contained the Light Sacred Dragon bloodline essence as well as his understanding of dragon-type martial souls, light-element power, and soul power cultivation. 28

• Removed the core despite knowing it would immediately collapse his remaining body. 28
• Entrusted it to Er Ming for Huo Yuhao to refine after recovering sufficiently. 28
• Huo Yuhao was later identified as Mu En’s last disciple after his death; it is not established that he ever refined the dragon core before Long Wushang killed him in Shrek City. 126

Sea God’s Light

As Master of Sea God Pavilion, Mu En could access Sea God’s Light, Shrek Academy’s sealed divine trump card. 23

• Activated it through a golden crystal bearing a trident imprint beneath Sea God Pavilion. 23
• Generated divine radiance that suppressed the Original Sin Demon Puppet and forced the Holy Spirit Cult to retreat. 23
• Its use consumed his blood, vitality, and the Golden Ancient Tree’s life energy. 23 24
• Only successive Sea God Pavilion Masters were qualified to access it. 23
• The radiance was remembered by Xuan Zi as genuine divine power, distinct from the authority of Long Wushang’s Original Sin contracts. 86
• Its barrier directly purified evil soul masters who touched or remained within it while nourishing and temporarily stabilizing Shrek’s wounded defenders. 24

Instruction and Administration

Mu En was an experienced mentor and administrator whose final orders reshaped Shrek’s post-attack structure. 13 27

• Guided Huo Yuhao in martial souls, cultivation, and the continent’s broader situation. 13
• Appointed Xuan Zi as acting Master of Sea God Pavilion, while requiring major decisions to be voted on by the Elders’ Council. 27
• Ordered Shrek’s soul tool department to receive resources equal to the martial soul department. 27
• Directed Zhuang Lao to build a wartime medical system after Shrek’s healing response proved inadequate. 27
• Assigned Song Lao to maintain order in Elders’ Council deliberations and restrain Xuan Zi’s impulsiveness when necessary. 27
• Requested that Er Ming represent the Clear Sky Sect in an alliance with Shrek and remain at the academy for half a year while its defenses and internal structure were rebuilt. 27

Relationships

• Long Xiaoyao — Former close friend and longtime counterpart; their Light and Dark Sacred Dragons clashed during the Holy Spirit Cult’s assault on Shrek. Long Xiaoyao’s support for his son directly enabled the attack that exhausted Mu En’s lifespan, though their old friendship and political relationship remained more complex than a simple enmity. 15 17 22 133
• Ye Xishui — Former close friend whose past relationship with Mu En and Long Xiaoyao remained emotionally unresolved. 15 16
• Long Wushang — Enemy and son of Long Xiaoyao and Ye Xishui; Mu En attempted to persuade him to leave the Holy Spirit Cult but regarded his Original Sin Demon Puppet as a grave potential threat. Wushang led the assault on Shrek, and Xuan Zi later held him responsible for the attack, Mu En’s death, and Huo Yuhao’s eventual death. 15 16 81 126
• Huo Yuhao — Student under Mu En’s guidance; Mu En rescued him from Long Wushang, arranged treatment, and left him the dragon core as a future inheritance. Huo Yuhao later recovered enough to resume cultivation and soul-tool studies, but was ultimately killed by Long Wushang in Shrek City; Xuan Zi identified him as Mu En’s final disciple. 13 22 28 56 126
• Yan Shaozhe — Disciple and Shrek dean; Yan Shaozhe remained at Mu En’s side during his final instructions and mourned his death. Mu En had judged him too straightforward and insufficiently broad-minded for major leadership, an assessment Xuan Zi later invoked to guide him. Yan later reached Rank 98 after taking the Yin-Yang Creation Pill. 24 28 133 138
• Xuan Zi — Chosen by Mu En to temporarily lead Sea God Pavilion after his death, subject to oversight by the Elders’ Council. Xuan Zi later worked to advance Mu En’s soul-tool reforms and eventually became Shrek’s new Ultimate Douluo. After inheriting Mu En’s responsibilities, he came to understand the value of Mu En’s farsighted leadership and attempted to pass those lessons on to Yan Shaozhe. 27 56 92 133
• Song Lao — Elder entrusted by Mu En with maintaining order within Sea God Pavilion and checking the weaknesses of Xuan Zi and Yan Shaozhe’s leadership. 27
• Zhuang Lao — Healing elder ordered by Mu En to establish a dedicated wartime medical system and improve Shrek’s emergency treatment capacity. 22 27
• Er Ming — Entrusted with protecting Shrek for half a year and personally supervising Huo Yuhao’s eventual refinement of Mu En’s dragon core. 27 28
• Wang Dong — Mu En entrusted Wang Dong with caring for Huo Yuhao during his final moments. 28
• Beibei — Mu En’s great-grandson; Mu En had previously dispatched people to search for the missing Tang Ya at Beibei’s request. 3

Story Role / Major Arcs

Holy Spirit Cult Assault on Shrek

When Long Xiaoyao and the Holy Spirit Cult attacked Shrek City, Mu En transformed into the Light Sacred Dragon and defended the city against the Dark Sacred Dragon and coordinated soul-tool bombardment. He recognized that the assault’s real purpose was to slaughter Shrek’s younger generation and destroy the academy’s future. 13 14 15

Forced to choose between remaining as Shrek City’s shield or confronting Long Xiaoyao, Mu En left behind a defensive light barrier and burned his remaining lifespan to enter the battle. 15 17

The assault demonstrated the changing nature of warfare to Mu En: coordinated soul-tool artillery, even without Title Douluo operators, pinned an Ultimate Douluo into a defensive role and inflicted damage the Golden Ancient Tree could not repair quickly enough. 14

Confrontation with Long Wushang

Mu En attempted to persuade Long Wushang to abandon the Holy Spirit Cult, arguing that evil soul master power would eventually consume him. Long Wushang rejected the appeal and challenged Mu En’s authority to judge him or Tang Ya. 16 17

The exchange forced Mu En to confront the limits of his own principles: he acknowledged through silence that he might have treated Wushang as an unacceptable threat had the youth not been protected by his lineage. 16

Sea God’s Light and Final Sacrifice

After rescuing the critically injured Huo Yuhao, Mu En activated Sea God’s Light as Shrek’s last resort. The divine power suppressed the invading evil soul masters, compelled the Holy Spirit Cult’s withdrawal, and saved the academy from immediate destruction. 22 23

The activation exhausted what remained of his life force. Even while dying, Mu En organized Shrek’s reconstruction, reformed its leadership structure, established new medical priorities, and demanded greater investment in soul tools. 24 27

Death and Legacy

Mu En removed his dragon core and entrusted it to Er Ming for Huo Yuhao’s future recovery. He then gave Xuan Zi a final instruction to value the lives of Shrek’s children above its glory before his body dissolved into golden motes and merged with the Golden Ancient Tree. 28

A Light Sacred Dragon manifestation appeared following his death, healing the injured and repairing portions of the devastated city. 28

Mu En’s institutional reforms continued to shape Shrek after his passing. Under Xuan Zi, the academy developed soul-tool technology, promoted an exchange program with the Sun Moon Imperial Soul Engineering Academy, and supported soul-tool-related industries in Shrek City. 56 79

Xuan Zi’s eventual breakthrough to Ultimate Douluo restored Shrek’s possession of an Ultimate Douluo-level protector, partially fulfilling Mu En’s concern that the academy would lack a top-tier deterrent after his death. 27 92

Mu En’s teachings also continued to shape Shrek’s leadership after Xuan Zi inherited the burden of Sea God Pavilion. Xuan Zi came to appreciate Mu En’s insistence on broad judgment, restraint, and prioritizing institutional survival over personal hatred, and used those lessons to challenge Yan Shaozhe’s rigid outlook. 133

Huo Yuhao remained publicly regarded as Mu En’s last disciple and one of Shrek’s greatest hopes until his death in Shrek City. His loss deepened the consequences of the conflict Mu En had attempted to avert during the Holy Spirit Cult assault. 126

Yan Shaozhe’s breakthrough to Rank 98 later strengthened Shrek’s senior leadership and made Mu En’s former aspiration for a renewed top-tier Shrek protector more attainable. 138
