Background / History

Mu En and Xuan Zi found Mu Xuanheng alone after his arrival in the Douluo world. Recognizing that the child suppressed their martial souls, they brought him to the Sea God Pavilion and raised him until his martial soul awakening. 1

At the awakening ceremony, Mu En identified Mu Xuanheng's first martial soul as Chaofeng, the third of the Nine Sons of the Dragon God. He also recognized the unprecedented implications of the Contract martial soul and Mu Xuanheng's Innate Full Soul Power. 1

Mu En accepted Mu Xuanheng as his disciple and ordered that both Chaofeng and Contract be concealed. To protect him, Mu En and Xuan Zi publicly presented Chaofeng as a mutated Bright Holy Dragon named the Phantom Scale Dragon. 2

He personally directed Mu Xuanheng's training, tested his soul skills, arranged special nutrition and intensive exercises, and continually evaluated the limits of his disciple's combat ability. 5 6 Although he worried that Mu Xuanheng's overwhelming strength left him without peers to pressure his growth, he continued to support the child's independent decisions. 7 8

Mu En accompanied Mu Xuanheng to the Extreme North in pursuit of a third soul ring. There, he confronted Ye Xishui while trying to protect his disciple during Xue Di's sealing and eventual contract. The battle further damaged Mu En's already declining health. 14

As his condition worsened, Mu En asked Mu Xuanheng to assume responsibility for Shrek's future. 15 Even while unable to fight at full strength, he continued to guide Shrek through threats from the Holy Spirit Cult and cautioned that the Sun Moon Empire was likely assisting a powerful Evil Soul Master. 41

Using Life Gold and Electrolux's precise control, Mu Xuanheng restored Mu En's vitality, healed his long-standing injuries, and allowed him to stand without his wheelchair. Mu En recovered as a true Ultimate Douluo. 51

Mu En remained fiercely protective of Mu Xuanheng, reprimanding and sealing Xuan Zi after repeated failures to prioritize the disciple's safety. 59 He later helped oversee the Soul Contract Pavilion alongside Di Tian, managing its development after its public launch. 103

During the conflict with the Demon Empress, Mu En drew on the Golden Ancient Tree's power to raise his strength beyond its normal limit and isolate the Demon Empress in a one-on-one battlefield. 117

Appearance

Mu En was initially confined to a specially crafted wheelchair Soul Tool because of his severe injuries and deteriorating vitality. After being healed with Life Gold, he regained the ability to stand and no longer required it. 14 51

• Often addressed as an elderly master or “Elder Mu.”
• Possessed a calm, authoritative presence capable of restraining even other high-ranking Soul Masters.
• Used a wheelchair Soul Tool before his recovery. 14 51

Personality

Mu En is patient and reassuring toward Mu Xuanheng, particularly during the latter's frightening martial soul awakening. He consistently prioritizes the boy's safety over the value of powerful soul beasts, rare resources, or political concerns. 1 2 59

He is also cautious and pragmatic. Mu En immediately understood that Contract could disrupt the foundations of the soul master world, so he imposed strict secrecy until Mu Xuanheng could defend himself. 2

Despite his gentleness toward his disciple, Mu En can be severe with those he considers irresponsible. His rebuke of Xuan Zi makes clear that he views Mu Xuanheng as Shrek's most important hope. 59
