Background / History

Earlier Life and Injuries

Mu En made his name earlier than Xuan Zi, despite the two belonging to the same era and being relatively close in age. He often looked after Xuan Zi on his senior brother’s behalf, establishing the respect behind Xuan Zi’s treatment of him as a junior martial uncle 34.

In his youth, Mu En was sharp-edged, aloof, and dismissive of his peers. His later affection for Su Yuan partly comes from recognizing that same temperament in the boy 51. He also avenged Zhang Lexuan, a kindness that—alongside Shrek’s years of raising and nurturing her—became a central reason for her loyalty to the academy 72.

Mu En suffered a broken spine, persistent erosion from the Dragon Core’s baleful energy, and extensive soul damage. These injuries tormented him for decades. Wang Xian’er examined him shortly after becoming a Titled Douluo but could not help at that time; even the Golden Tree’s long-term nourishment could only suppress his pain and deterioration 73.

Welcoming Su Yuan

When Su Yuan arrived at Shrek, Mu En was sunbathing outside the freshman dormitory. After receiving Wang Xian’er’s greetings and seeing her token, he welcomed her junior and gave him a Golden Tree token. He invited Su Yuan to seek help from either him or Martial Soul Department dean Yan Shaozhe 45.

Mu En subsequently observed Su Yuan cleaning his room with a precisely controlled ice attack. He praised the boy’s martial soul, cultivation, and control, but remained troubled that Shrek had no one ready to replace him as its pillar 46.

After Su Yuan injured Zhu Wennan, Mu En checked the victim’s condition and judged that his life was not threatened and his arms could recover. He treated the incident as a student dispute, sided with Su Yuan, and agreed to arrange a private room and dormitory renovations, while warning him against causing another major commotion 48 56.

Over the following months, Mu En and Su Yuan regularly shared tea and conversation. Mu En watched Huo Yuhao defeat Wang Dong, explained that her defeat reflected her lack of Huo Yuhao’s fearless heart, and later cautioned Su Yuan about speaking too harshly to her 50 51 59.

Seeking Treatment

Mu En encouraged Xuan Zi’s visit to investigate Wang Xian’er’s advancement, recognizing the potential importance of a healing-type Limit Douluo 34. When she later returned to Shrek at that realm, he requested treatment and offered to meet her price. His urgency came from Shrek’s lack of a successor: he believed he could not leave the academy’s burdens to an unprepared generation 73.

Wang Xian’er’s nine hundred-thousand-year soul rings and yin-yang complementary dual soul cores overturned his expectations of what a Soul Master could achieve. Her infusion of vitality temporarily suppressed his pain, and she confirmed that his body could be healed 73 74.

Treatment condition	Details
Cost to the healer	Approximately 200 years of Wang Xian’er’s lifespan 74 88
Recoverable damage	His physical injuries and the vicious energy within his body 74
Permanent limitation	Existing soul damage is irreversible; even after physical recovery, his remaining lifespan would be roughly 30–50 years 74
Fallback assistance	Wang Xian’er offered to extend his life by a few months if he could not afford full treatment 74

Shrek’s elders unanimously supported healing him, but disputed how the departments should share the expense. Mu En declined to impose a unilateral decision because he was the beneficiary. He also saw the negotiations as an opportunity to strengthen the Soul Tool Department, whose freedom to recruit students had been restricted by the Martial Soul Department 85.

The agreed payment included the following resources 85 88:

Resource	Quantity / Details
Hundred-thousand-year soul bones	Three limb bones for different limbs and one head bone
Rare metals	Ten tons
Level 8 soul tools	Ice-attribute dragon spear, reusable shield, and soul-piercing ray
Cultivation resources	Assorted spiritual herbs, treasures, and medicinal pills
Gold Soul Coins	50 million
Dragon Core	Mu En’s treasured core

The material payment exceeded 500 million Gold Soul Coins in value, with the Dragon Core itself considered beyond ordinary monetary valuation. Treatment would also leave Mu En owing Wang Xian’er a personal debt of gratitude 85 88.

Mu En had originally reserved the Dragon Core for a future Shrek successor, or for Bei Bei if no suitable successor emerged. He instead offered it as the decisive bargaining chip, reasoning that its usefulness to Su Yuan’s dragon martial soul would persuade Wang Xian’er 86.

Wang Xian’er accepted the offer. Mu En paid in advance through a starlight-sapphire storage ring and provided her with a room in the Sea God Pavilion. Formal treatment was scheduled to begin the following day; its completion is not shown in the supplied passages 88 89.

Appearance

Mu En appears as an elderly man with deeply wrinkled features and an unmistakable air of physical decline 45.

• Often rests in a recliner outside the freshman dormitory, sunbathing and watching students 45 50.
• Uses a cane 73.
• His back injury makes movement difficult, including rising to greet visitors 88.

Personality

Mu En is approachable and quietly playful. He enjoys watching freshmen’s dramatic encounters and readily joins Su Yuan for tea. Although he appreciates Su Yuan’s sharpness and independence, he also believes the boy should learn the value of friendship and understand that cruel words can wound 49 50 51.

His concern for Bei Bei is affectionate rather than rigidly ambitious. He hopes his only blood descendant might become another pillar of Shrek, yet would rather see him happy and free from the exhausting obligations that shaped his own life 47.

Shrek’s survival governs Mu En’s decisions. He spends considerable effort securing treatment so he can continue protecting it, but is willing to let internal negotiations produce reforms rather than simply assert his authority 73 85 86. His leniency toward Su Yuan also has boundaries: Su Yuan understands that killing someone inside the academy would bring Mu En’s intervention because it would implicate Shrek 56.

Abilities & Skills

Light Sacred Dragon

Mu En’s martial soul is a pure true-dragon martial soul, described as one of the strongest dragon martial souls available to a mortal without extraordinary fortune 71.

• Produces soul power characterized by supreme strength and pure yang energy, making it effective against evil powers 12.
• Possesses the purity and full draconic capabilities of a sacred dragon rather than an earth dragon or mixed-blood sub-dragon 71.
• Does not possess the ultimate light attribute 82.

Anti-Evil Techniques

Mu En created two ultimate techniques specifically to counter Evil Soul Masters 12:

• Dragon Emperor Evil-Splitting Rend
• Dragon Emperor Domain-Shaking Realm

Su Yuan considers Mu En capable of removing the Spirit-Devouring Carving Knife’s curse through his martial soul, Limit Douluo cultivation, and access to the Golden Ancient Tree’s power. Mu En does not personally perform that purification in the supplied chapters 12.

Sovereign’s Arrival and Perception

Mu En has developed Sovereign’s Arrival. Wang Dong’s Clear Sky Sect disguise is only partially effective against him, allowing him to recognize that she is a girl 50.

• He cannot discern her hidden soul-beast ancestry 50.
• He assesses Su Yuan’s soul-power control and combat output through observation 46 48.
• He mistakes Profound Ice Dragon Soars for a skill from a ferocious-beast soul bone at least 200,000 years old, ruling out a self-created technique at Su Yuan’s age and cultivation 48.

Golden Ancient Tree Connection

Mu En can draw upon the Golden Ancient Tree’s power 12.

• Its nourishment suppresses his chronic injuries and pain but cannot cure them 73.
• Tokens made from its wood calm the mind, focus the spirit, and gather surrounding Heaven and Earth Essence, indirectly aiding cultivation 46.

Equipment / Weapons / Items

• Dragon Core — Treasured for years as a resource for nurturing Shrek’s next protector; ultimately included in Wang Xian’er’s medical payment 85 86.
• Golden Tree token — A heavy wooden plaque bearing the character “Mu” and gentle light energy. Given to Su Yuan as both a cultivation aid and proof of Mu En’s backing 45 46.
• Cane — Used while moving around the dormitory area 73.
• Soul Tool — Used to store and retrieve the treatment-payment list 88.

Relationships

• Bei Bei — His only blood descendant. Mu En balances hopes for his future strength with a desire for him to live happily; Bei Bei was also a possible recipient of the Dragon Core 47 86.
• Wang Xian’er — An old acquaintance and former unsuccessful healer of his injuries. After reaching Limit Douluo, she becomes the healer with whom he negotiates a costly treatment agreement 45 73 88 89.
• Su Yuan — Wang Xian’er’s junior, whom Mu En welcomes, protects, and advises. Their tea conversations remind Mu En of his own youth 45 48 51.
• Xuan Zi — Addresses Mu En as his junior martial uncle. Mu En looked after him in their earlier years; Xuan Zi strongly supports restoring Mu En so Shrek remains protected 34 85.
• Yan Shaozhe — His disciple and the Martial Soul Department dean. Mu En directs Su Yuan to him for assistance and shares his assessment of Su Yuan’s ice-dragon attack 45 61 85.
• Zhang Lexuan — Mu En avenged her in the past. His kindness is a major foundation of her loyalty to Shrek 72.
• Wang Dong — A freshman whose disguise he sees through and whose defeat he uses to offer a lesson about courage 50.

Story Role

Source of the “Feed Douluo” Trait

• An iconic feeding scene unlocks Su Yuan’s Feed Douluo system entry, described as a gift associated with Dragon God Douluo Mu En’s legacy 71.
• The single-use entry evolves Su Yuan’s Frost Dragon into an Ice Soul Sacred Dragon equivalent in martial-soul strength to Mu En’s Radiant Sacred Dragon; it expires after the evolution 71.
• Su Yuan activates it during his fusion with the Ice Empress’s soul bone. Combined with her power, the transformation produces the ultimate-ice Frost Saint Dragon, whose martial-soul strength surpasses Mu En’s 81 82.
• This is a system-derived reward, not a consciously taught technique or direct transfer performed by Mu En 71 81.
