Mu Hongchen

Biodata

Background / History

Mu Hongchen is introduced as a brilliant soul engineer, close friend, and collaborator of Yin Hongye 16 20. Known for consuming metal above the Spirit Forging grade and grinding relentlessly, he possesses exceptional technical expertise and a relaxed, pragmatic demeanor 16 18 100. He operates advanced soul tools like a Black-Class Mecha, Flying Soul Tools, and Titan Tunneling Machines, and he plays an integral role in researching cutting-edge technology—including positive-cycle source positive-feedback loops and short-range spatial folding 16 25 71 94.

Throughout the narrative, Mu Hongchen acts as both an expositor of historical context and a co-conspirator with Yin Hongye in manipulating factions like the Federation, Shrek Academy, the Tang Sect, and the Spirit Pagoda 20 43 72. He frequently funds or organizes media coverage, hacks databases, and helps orchestrate public disruptions and challenges against powerful institutions 20 35 43. A graduate of Sun Moon Royal Soul Engineering Academy, he remains notorious there for leading students in rebellion alongside Yin Hongye 74.

Mu Hongchen is a descendant of Xiao Hongchen. After the Hongchen Family finally returned to Mingdu following ten thousand years of decline, he became its only member in a century to inherit the Three-Legged Golden Toad Martial Soul. The elders consequently placed the responsibility of reviving the family on him, burdening him with severe pressure. He vented online and crashed the Federation's network, eventually meeting Yin Hongye when the two were imprisoned together 93 152 204 205.

Mu Hongchen absorbs the Three-Legged Golden Toad Soul Spirit during a joint ascent of the Spirit Pagoda’s Soul Spirit Tower 18 19. During the demon outbreak at the Yuanen Family, he uses his Flying Soul Tool to evacuate family members, coordinating with Yuanen Zhentian to move everyone to the battlefield's edge before Yin Hongye unleashes his more destructive attacks 30. He later invites Yuanen Yehui to accompany the group and helps arrange a new identity and a home in Mingdu for the amnesiac Na'er 34 36 38.

His Mingdu residence initially consists of a three-story building near the Central Legion, with unfinished soul tools on the first floor, a workshop on the second, and living quarters on the third. While Yin Hongye spends half a year condensing his third Soul Core, Mu Hongchen teaches Na'er and Yuanen Yehui, including instructing Yehui in soul-tool construction 38 46 48.

Later, he helps raid the Star Luo Tang Sect’s underground factory and stores, implants a virus in its production system, and takes charge of the Green Skeleton forces while Yin Hongye’s group enters Dragon Valley 153 154 157. He also collaborates with Yin Hongye on an Anti-Magic Domain and a spatially looping prison 172.

After Yin Hongye refines the Heavenly Creation Pills, he gives one to Mu Hongchen to aid his cultivation. Mu Hongchen plans to take it that night and initially expects to break through to Titled Douluo within the year, later confidently predicting that he will have advanced by Yin Hongye's return from Devil Island. Yin Hongye advises him to prepare Four-Word Battle Armor once he reaches the appropriate limit 185. By the time he demonstrates his ninth Soul Skill and Mechanical Conversion, he has reached the nine-ring stage; his status as a Titled Douluo is explicitly recognized during his later fight with Su Mengjun 201 205.

Mu Hongchen and Yin Hongye notice a Godslayer Soul Missile being transported toward the Former Site of the Evil Demon Forest. Believing Shrek Academy to be its target, they decline to intervene and argue that the academy and its powerful residents can defend themselves 197. Yin Hongye subsequently offers to forge Heavenforged Metal for Mu Hongchen, who requests the Metal Attribute with its power devoted entirely to attack 197.

After completing his Four-Word Battle Armor, Mu Hongchen accompanies Yin Hongye, Qian Renxue, Di Qiuer, and Na'er to the War God Temple's Eighteen Layers of Hell. He criticizes its outdated Soul Guidance Arrays and supports redesigning its challenges. During the visit, he defeats Su Mengjun through his metal manipulation, prompting her to concede 204 205.

He continues researching with Yin Hongye, but the pair abandon attempts to extract energy from the Ice God's Heart because the yield does not justify the investment. They also plan to disguise their looping prison as a Soul-Guided Train tunnel connecting Mingdu with Qiankun Asking Love Valley 212. At the Abyssal battlefield, Mu Hongchen provides precise cannon support from behind Yin Hongye's Blood Sea 216.

Following a request for Yin Hongye to help improve his Soul Rings, Mu Hongchen farms the Advanced Ascension Platform until all his rings reach 100,000 years 213 229 230. He later tears open and stabilizes a spatial passage into the Myriad Beast Platform when its plane rejects the group's entry 241. During a subsequent infiltration, he dismantles a dense alloy barrier designed to block spiritual power, opening a discreet route for the group 252.

Appearance

Mu Hongchen typically wears a spotless white lab coat, projects a laid-back and confident posture, and is frequently seen interacting with data tablets, gold coins, or specialized soul equipment 71 75 100.

• Has silver hair; on his first in-person appearance, he wears a bright purple silk shirt, a black embroidered jacket, silver-gray trousers, and polished shoes 17.
• Wears a spotless white lab coat 71.
• Pilots advanced mechas and flying soul tools 25 89 94.
• When possessed by his Three-Legged Golden Toad Martial Soul, his body takes on a golden covering, golden protrusions rise beneath his clothing, and an additional golden leg extends behind him 18 205.
• Wears glasses during a later discussion of historical events 240.

Personality

Mu Hongchen is calm, collected, and relentlessly focused on technological research and problem-solving, showing little regard for personal wealth or traditional reputations 99 100. He shares a cynical, chaotic worldview with Yin Hongye, enjoying corporate and political sabotage, mocking rigid traditional institutions like Shrek Academy and the Tang Sect, and treating high-stakes battles as light entertainment complete with snacks 50 57 100. Despite their banter, he shows concern when Yin Hongye discusses his family history 17.

He takes considerable pride in his research and hopes his technology will change the era and make his name widely remembered 89. His technical enthusiasm remains tempered by practicality: he readily abandons the Ice God's Heart project when its energy return proves insufficient 212.

Mu Hongchen rejects conventional martial ethics in favor of effective tactics and material advantage. He describes rules as restraints that the strong break and the stronger define, and argues that profit can lead people to trample everything 36 82. Nevertheless, he actively helps protect and teach the younger companions and participates in evacuating the Yuanen Family during the demon crisis 30 34 36 46 48.

Although he mocks nepotism and says he does not rely on his family for a living, his own history is marked by the pressure of his family's expectations 82 205. He also recognizes sustained effort in others, explaining that Dong Zi'an's battlefield experience and hard work prepared him to seize an opportunity to understand space 227.

Abilities & Skills

Soul Engineering & Technology

• Highly skilled researcher and tinkerer capable of developing advanced ninth-grade soul tools, flying tech, and mechas 94 122.
• Proficient in hacking institutional databases, such as the Eastsea Legion network; he also implants a virus in a Tang Sect factory’s core control system 35 153.
• His past cyberactivities include crashing the Federation's network under the pressure of his family's expectations. He also uses Cai Yue'er's account to argue online without attracting suspicion 27 60 205.
• Developer of experimental mechanics like the Positive Cycle Source and short-range spatial folding. He produces a costly positive-cycle source core and tests it in a large mecha, though cooling and production remain obstacles 61 71 94.
• Collaborates on an Anti-Magic Domain and a spatially sealed, looping prison, while acknowledging that their more ambitious spatial systems require additional computing expertise 172.
• Develops soul-tool technology for psychological disruption, used to interfere with opponents outside the arena 108.
• Studies Source Positive Feedback Loop combinations with Yin Hongye and Ling Zichen, exchanging contact information with Ling Zichen for continued collaboration 99.
• Identifies a Godslayer Soul Missile by sensing its metal structure and recognizing its distinctive Source 197.
• Helps plan a looping-space prison disguised as a train route to Qiankun Asking Love Valley. Their proposed use of a Shrek Academy graduate is intended to divert attention from the scheme 212.

Combat & Support

• Possesses combat and tactical support capabilities matching high-level soul masters, utilizing soul-tool-enhanced cannons and specialized mechas 18 19.
• Can control and reshape large quantities of metal, particularly where metal is abundant. At the Star Luo Tang Sect, he opens alloy flooring to expose a hidden passage; at Green Skeleton, he melts nearby mechas below black grade 152 154.
• Provides communications denial and battlefield support, including blocking the Tang Sect’s signals during the confrontation at the Ice-Fire Yin-Yang Well 124.
• Excels at long-range combat and fighting in open terrain. Yin Hongye describes him as becoming stronger with greater fighting distance and likens him to a walking war machine 201.
• By the time he develops Mechanical Conversion, he judges himself capable of exchanging several blows with an ordinary Super Douluo 201.
• Defeats Su Mengjun at the War God Temple with adaptable metal constructs, including self-rejoining barriers and a metal beast 205.
• Operates a battery of Soul Guidance Ray cannons at maximum power during the Abyssal fighting, accurately targeting approaching Abyssal Creatures from a raised position behind the Blood Sea 216.
• Uses his Flying Soul Tool's protective light barrier to carry evacuees during the Yuanen Family's demon outbreak 30.

Martial Soul & Metal Manipulation

• Three-Legged Golden Toad — Inherited Martial Soul of the Hongchen Family. Mu Hongchen is the family's only inheritor of it over the preceding century 205.
• Compatible Soul Spirit — His contracted Three-Legged Golden Toad Soul Spirit perfectly matches him and is stated to greatly improve his future cultivation speed 19.
• Ninth Soul Skill — Allows him to make use of most metals he touches. At the War God Temple, surrounding metal softens and flows under his control, forming branches and waves that can rejoin after being cut apart 201 205.
• Mechanical Conversion — A technique developed from his ninth Soul Skill that rapidly switches metal between different soul tools. He demonstrates transforming a close-combat soul tool into a Fixed-Installation Soul Cannon and can make controlled metal behave almost like living material and continue growing 201.
• Fine Structural Control — Can loosen an alloy plate's molecular structure and part it without relying on ordinary penetration methods, bypassing a barrier specifically designed to block spiritual power 252.
• Unrealized Applications — He considers controlling trace iron in human bodies a future possibility. He also theorizes that remotely dismantling, retrieving, and reassembling metal could become possible if he reaches Limit Douluo and masters the necessary spatial abilities; neither application is demonstrated in these discussions 152 201.

Spatial Abilities

• Tears open a spatial rift into the Myriad Beast Platform after the plane refuses entry, then stabilizes the passage long enough for the group to enter 241.
• His demonstrated creation of this passage does not establish that he has reached Limit Douluo or achieved his proposed remote metal-retrieval technique 201 241.

Power Progression

Equipment / Weapons / Items

• Black-Class Mecha — Exclusive, high-tier mecha used for long-distance travel and combat 16.
• Red-Class Mecha — Piloted by Mu Hongchen during later travel with the group 78 89.
• Experimental Large Mecha — An approximately eighty-meter machine built to test positive-cycle source energy output. Its energy attacks are powerful but limited by overheating and high costs 94.
• Flying Soul Tool — Advanced golden-winged transport vehicle equipped with auto-following features 100.
• Titan Tunneling Machine — Underground transport used to navigate into protected areas like the Sunset Forest 121.
• Ninth-Grade Soul Tools & Cannons — High-grade equipment utilized for combat and operations at the Ice-Fire Yin-Yang Well 19 122.
• Heavenly Creation Pill — Given to him by Yin Hongye to support a planned Titled Douluo breakthrough 185.
• Four-Word Battle Armor — Completed by the time of his visit to the War God Temple; its name and individual abilities are not specified 204.
• Soul Guidance Ray Cannons — Operated as a coordinated battery for precise, maximum-power fire against Abyssal Creatures 216.
• Requested Metal-Attribute Heavenforged Metal — Yin Hongye offers to forge it for him; Mu Hongchen asks that its properties focus entirely on attack 197.

Relationships

• Yin Hongye — Close friend, primary collaborator, and partner in crime; shares mutual trust and dry banter while disrupting mainland factions. Mu Hongchen supports Yin Hongye’s research and operations, and Yin Hongye gives him a Heavenly Creation Pill to aid his cultivation 16 50 99 185. Their association began when they were imprisoned together following Mu Hongchen's disruption of the Federation network. Yin Hongye later offers to forge attack-focused Heavenforged Metal for him and helps raise all his Soul Rings to 100,000 years 197 205 230.
• Qian Renxue — Companion in travels; observes and participates in their team operations. Mu Hongchen explains modern technology and history to her and sometimes teases her about her past decisions 18 20 135. He also helps arrange a quiet room for her Soul Core cultivation and cautions her to consider her spiritual power before attempting Yin-Yang Complementarity 46.
• Di Qiuer, Na'er, & Yuanen Yehui — Companion observers whom he guides or transports during field events. He also teaches Na’er and Yuanen Yehui while Yin Hongye is in seclusion 46 48 57 100. He invites Yehui to travel with the group, helps establish Na'er's identity in Mingdu, and assists the Auspicious Beast in choosing a human appearance 34 38 86.
• Ling Zichen — Fellow soul-engineering researcher whose work on positive-cycle sources interests him. He meets her during the Federation’s satellite project, and later discusses obtaining her help for a computing-intensive prison system 61 75 78 172. They directly collaborate on Source Positive Feedback Loop combinations and exchange contact information for further research 99.
• Xiao and Meng Hongchen — Figures from ten thousand years earlier who watch Mu Hongchen through the Heavenly Screen and regard him as a descendant. Meng praises his metal control, while Xiao takes his example as a challenge to improve 88 93 152 154. Mu Hongchen's later Mechanical Conversion again astonishes Xiao, whose own metal-control practice remains far more limited 201.
• Hongchen Family — His family regards him as its hope for revival because he alone inherited the Three-Legged Golden Toad Martial Soul over the preceding century. Their expectations nearly crush him and contribute to his destructive online behavior 204 205.
• Xu Tiankuo — A familiar Federation contact whom Mu Hongchen knows through his repeated encounters with imprisonment. Xu Tiankuo helps coordinate security preparations, but rejects Mu Hongchen's request for one trillion in research funding, prompting Mu Hongchen to say he will transfer the money himself 77 99 170.
• Su Mengjun — War God Temple opponent who knows about his family's expectations. Mu Hongchen defeats Su Mengjun with his ninth Soul Skill and metal constructs, earning an acknowledgment of his strength 204 205.
