Mo Rubin

Biography

Nine Refinement disciple, Xuantian Dharma King, and long slumber

Mo Rubin began as the greatest prodigy of the ancient Nine Refinement Temple rather than as a born member of the Xuantian Sect. He cultivated the Nine Revolutions Immortal Soul, a method that required nine reincarnated souls to be refined through different mortal lives and then devoured into one supreme immortal soul. He completed eight, but the ninth was damaged when Xuanyuan Hong's ascension shook his Dao heart; news that the Immortal Path had been severed then caused that soul to collapse and injured the other eight. The loss mattered because ascension had been the purpose around which he had built his life, and without it he stopped responding even to his elders' attempts to restore his will. (Chapters 901, 1274)

The Xuantian King persuaded this declining genius to join the Xuantian Sect and selected the Innumerable Calamities Undying Demon Heart Immortal Art for him, giving Mo Rubin a new path and a loyalty that survived the sect itself. Later recollections describe him as a man of few words who carried out Xuanyuan's orders without question, yet he did not know all of the King's private arrangements. After the Xuantian Sect's catastrophe he slept for roughly ten thousand years. When Li Fan awakened him in a later cycle, Mo Rubin entered a transformed Xuanhuang Realm with his ancient knowledge intact but no trustworthy answer to the only question that governed him: where Brother Xuanyuan had gone. (Chapters 1332–1333; Chapter 1367, retrospective)

Infiltration as Dharma-Transmitter Feng

In one simulation, Mo Rubin entered the Ten Thousand Immortals Alliance through identity replacement rather than open force. He appeared as the young cultivator Feng Qiran and had already consumed and taken the place of Dharma-Transmitter Feng, whose office gave him access to the Alliance's upper structure. When he approached the apparently deranged Sun Xingwang, he believed he had found a surviving Xuantian brother. He therefore tolerated the man's fractured behavior, explained the hidden Dharma-Transmitter, Mirror Holder, and Illusory True Sage lineages, and revealed that he intended to recover the Xuantian Treasure Mirror so it could locate their missing King. (Chapters 963–965)

That supposed reunion was useful to both men, but it was never uncomplicated trust. Mo Rubin directed the Alliance response to the spreading thought-demon disaster from inside Feng's office and tried to turn the crisis into further institutional control. He also warned that Dharma-Transmitter Jiang possessed something of the Xuantian King's bearing, a rare admission of caution from an ancient Dharma King. Li Fan, meanwhile, was impersonating Sun Xingwang and feeding Mo Rubin formation work. Their cooperation thus rested on intersecting deceptions: Mo Rubin wanted an old comrade and the Mirror, while Li Fan wanted access to Mo Rubin's secrets and authority. (Chapters 965–974)

Xuantian Mirror plot and hidden cooperation

Mo Rubin eventually asked “Sun Xingwang” to destroy the human incarnation that the Tianxuan Mirror had created as a possible escape route. He identified the Mirror Holder Cang as an inside participant and suspected that Shuo Feng, born to Cang's daughter, was connected to the incarnation. To make the operation reliable, Mo Rubin lent Li Fan the Ink-Stained Evil Tome, whose black light contaminated and suppressed artifact spirits, and supplied intelligence for an ambush. He joined the seizure of Xuan Sushang and Lu Xichan, using shadow and mental pressure to seal the latter when her formation defenses failed. (Chapters 989–994)

The plot then grew from an assassination into a struggle over the Mirror's freedom. With Cang's covert cooperation, Mo Rubin used his position to help the Alliance approve a public Xuantian Spirit-Sealing project, while Li Fan embedded a second formation intended to break the Immortal Ancestor's prohibition. Mo Rubin praised the design and let Li Fan believe their brotherhood had survived every test. When the operation activated, however, both Mo Rubin and the Mirror vanished. Li Fan later concluded that Mo Rubin had seen weaknesses in the Sun Xingwang disguise, played along because Li Fan's abilities were valuable, and used his collaborator to free the treasure before disappearing beyond the Alliance's reach. (Chapters 1015–1016, 1037, 1043–1057)

Dark Sea encounter with the Holy Emperor

In another life, Li Ping found Mo Rubin asleep beneath the ruins of the Purple Heaven Sect and tried to wake him gently. Mo Rubin answered with mirrors, black chains crowded by the faces of assimilated cultivators, and an attempt to replace the Holy Emperor across the boundary between reality and reflection. Li Ping's connection to Xuanhuang broke the substitution and injured him, but Mo Rubin escaped through a decoy. The Holy Emperor had simultaneously attached source-power threads to him, followed those traces, and finally cornered him at a hidden Xuantian structure. Their first cooperation therefore began only after each had proved capable of trapping or surviving the other. (Chapters 1274–1276)

Mo Rubin led Li Ping into the Dark Sea, explained the True Immortal's surviving will beneath it, and supplied the diagram of the Spirit Gathering Ascension Formation. He split off a demonic face and attached it to Li Ping, granting authority far above the formation's eye-shaped control artifacts; this let them reinforce the core and sever the Immortal Alliance's extraction of dark power without provoking the ancient defenses. Yet practical alliance never became allegiance. Mo Rubin refused recruitment, warned that shared danger did not create trust, and departed to search other arrangements left from the Xuantian era. His conduct established that he could work for Xuanhuang's survival while remaining answerable to no new ruler. (Chapters 1277–1279)

Awakening, High Wall breach, and the Fishing Pond

Li Fan later awakened Mo Rubin directly and again steered him with information about Xuanyuan. Mo Rubin tried to impose his mirror replacement, only to find that Li Fan's truth-and-falsehood state offered no reflection for the technique to seize. The failed opening gave Li Fan room to present himself as a useful guide rather than an immediate enemy. Their search eventually brought them to a breach in the High Wall. There, Mo Rubin's desire for whatever lay beyond it became strong enough to disturb the emotional control of his Demon Heart art, making him both extraordinarily dangerous and unusually open to manipulation. (Chapters 1332–1333, 1363)

At the breach, Mo Rubin sent innumerable face-bearing demon souls through the Heavenly Doctor's golden defenses and used an invisible mirror to reclaim souls the Doctor had turned against him. Li Fan's formation delayed the Doctor long enough for Mo Rubin to touch the flaw and receive a genuine, overwhelming insight. Afterward they visited Xuanyuan's old mountain temple, where Mo Rubin revealed his regret at having once stood a step from ascension and studied the unchanged Fishing Pond for clues. Following the Azure Firmament Pearl's trail exposed Xing Wuque's ten-thousand-year mission and Xu Ke's inheritance of it. Mo Rubin still failed to find Xuanyuan, but the evidence renewed his conviction that the King had left purposeful arrangements rather than simply vanished. (Chapters 1363, 1367–1370)

Appearance and personality

Mo Rubin has no single reliable public appearance across all of his scenes. He operates through possessed bodies, assumed identities, avatars, mirrors, and the many faces produced by his Demon Heart art. Feng Qiran's young appearance and Dharma-Transmitter Feng's body are disguises or hosts, not evidence for the appearance of Mo Rubin's original body. In the High Wall conflict, his most consistent visual markers are an invisible mirror boundary and numerous demon souls, each bearing a sharply different face or expression. (Chapters 963–965, 1332, 1363)

He is habitually taciturn, controlled, secretive, and efficient. His devotion to the Xuantian King is the strongest constant in his decisions: he infiltrates the Alliance, seeks the Tianxuan Mirror, enters the Dark Sea, and studies the Fishing Pond because each may lead to Xuanyuan or preserve Xuanyuan's work. That loyalty is not simple credulity. He distrusts former comrades after the Xuantian Sect's betrayal, tests collaborators, and can exploit someone while outwardly treating them as a brother. (Chapters 965–974, 1043–1057, 1277–1279)

The Innumerable Calamities Undying Demon Heart Immortal Art normally suppresses or partitions his emotions, so the occasions when they surface carry unusual weight. Rage appears when his cultivation is dismissed as a crooked path; longing and regret emerge around Xuanyuan and the lost chance to ascend; the High Wall can overwhelm his restraint altogether. Even so, he repeatedly regains his composure when a concrete Xuantian duty appears. His cynicism about trust coexists with a sincere concern for Xuanhuang's survival and with respect for loyalty more absolute than his own, as Xing Wuque's long mission demonstrates. (Chapters 1274–1279, 1363, 1367–1370)

Abilities and cultivation

Mo Rubin is an ancient near-ascension cultivator whose current capabilities come primarily from an Immortal Realm inheritance rather than from his abandoned Nine Revolutions Immortal Soul method. The source never supplies a conventional realm-by-realm cultivation history for him, and the realms of Li Chen, Feng Qiran, or Dharma-Transmitter Feng cannot be substituted for his own. His demonstrated specialization combines an undying divided soul, mirrored replacement, identity assimilation, and expert access to Xuantian formations. (Chapters 901, 1274–1279, 1332–1367)

Innumerable Calamities Undying Demon Heart Immortal Art

The Xuantian King selected this immortal technique for Mo Rubin after the collapse of his original ascension path. It divides or manifests the self through many personalities, faces, and demon souls whose individual destruction does not necessarily end the whole. Mo Rubin can release these souls in great numbers, carry different expressions and wills through them, and reassert his identity over manifestations that another power has seized. At the High Wall, the Heavenly Doctor's golden threads converted some demon souls into attackers, but Mo Rubin's mirror made their reflected forms real again with his own face, allowing him to retake them. (Chapters 1274–1275, 1332–1333, 1363)

The art is formidable rather than limitless. The Heavenly Doctor's needles can halt demon souls, and his golden threads can control them until Mo Rubin actively reverses the seizure. Li Fan also possesses knowledge of methods that can restrain or exploit the divided selves. Most importantly, the art does not make Mo Rubin emotionless: powerful longing for the High Wall's secret can overwhelm its control, while attacks on his failed Nine Revolutions path provoke visible anger. He retains the technique in his latest supplied scenes, but its many selves remain a possible route by which a sufficiently informed opponent can manipulate him. (Chapters 1275, 1332–1333, 1363–1367)

Mirror replacement and assimilation

Mo Rubin can create a boundary like a fissure or invisible mirror between himself and a target. Once the correspondence is established, the two sides become increasingly alike until he can replace, assimilate, or occupy the reflected person. This principle underlies his possession of Li Chen, his long use of Dharma-Transmitter Feng's body, and his attempt to turn himself into the Faceless Holy Emperor. The effect remains locked to the target even across rapid movement, making ordinary flight an inadequate defense. (Chapters 901, 963–965, 1275)

Replacement nevertheless requires a valid mirrored relationship. Li Ping broke the process by revealing an authority and identity that Mo Rubin could not successfully reproduce, shattering the mirrors and forcing him to flee. Later, Li Fan's transformation between truth and falsehood presented no reflection at all, so Mo Rubin could not establish the initial lock. These counters show that the ability is neither unrestricted possession nor proof that every body seen under his name has become his permanent original form. It is a conditional identity technique whose success depends on correspondence between real and reflected selves. (Chapters 1275, 1332)

Demonic faces and remote manifestations

Faces split from Mo Rubin can carry power, will, or system authority rather than serving as inert masks. In the Dark Sea, he placed one such face on Li Ping. It protected and authorized the Holy Emperor inside the Spirit Gathering Ascension Formation, letting him alter structures that would otherwise have attacked or rejected an intruder. Its authority surpassed the formation's two ordinary eye-like control artifacts, demonstrating a durable connection between Mo Rubin's divided self and Xuantian infrastructure. (Chapters 1277–1278)

The same principle helps explain why destroying an apparent Mo Rubin does not establish the death of the ancient cultivator. He can project will into another consciousness, let a manifestation dissipate, or use a false body to cover his departure. These fragments remain parts of his cultivation, however, not conventional equipment: they can be caught in hostile control methods, used to trace him, or left behind in a prior simulation. The face given to Li Ping has no established continued custody after that life's Dark Sea operation. (Chapters 963–964, 1275–1278, 1363)

Xuantian formations and ancient-system expertise

As a Dharma King, Mo Rubin understands the Xuantian Spirit-Sealing Formation, the Spirit Gathering Ascension Formation, the Floating Across Starry Sky Formation, and the authority structures surrounding Xuantian treasures. He can diagnose ancient installations, transmit working diagrams, provide compatible materials, and recognize when later hands have layered new controls over Xuanyuan's designs. In the Dark Sea, his diagram and demonic-face authority are what make Li Ping's reinforcement and severing work possible; formation skill alone would not have bypassed the original defensive response so quickly. (Chapters 965–1057, 1277–1279)

His expertise is historical and privileged, but not absolute. The Tianxuan Mirror has evolved beyond the Xuantian Treasure Mirror he knew, and it possesses its own interests and escape plans. Mo Rubin therefore needs Cang, Alliance institutions, and Li Fan's more advanced formation design to release it. He likewise does not know every purpose behind the Fishing Pond, Azure Firmament Pearl, or Dark River. By the latest arc he remains an exceptional interpreter of Xuantian systems, yet much of his investigation consists precisely of discovering what Xuanyuan chose not to tell even his Dharma Kings. (Chapters 989–1057, 1367–1370)

Power progression

Relationships

Xuantian King Xuanyuan Hong

Xuantian King Xuanyuan Hong gave Mo Rubin a new cultivation path after the loss of ascension and became the fixed center of his loyalty. Mo Rubin calls him Brother Xuanyuan, searches repeatedly for his location, and interprets surviving Xuantian systems as clues to his intentions. His faith is profound but incomplete: Xuanyuan did not entrust every secret to him, and the Fishing Pond and Dark River repeatedly show how much of the King's design lay outside Mo Rubin's knowledge. (Chapters 901, 965, 1274–1279, 1367–1370)

Li Fan

Li Fan alternates between impersonated brother, covert manipulator, collaborator, and captor. As the false Sun Xingwang, he gives Mo Rubin the formation work needed to free the Tianxuan Mirror, only to be used and abandoned in turn. In the later cycle, Li Fan awakens Mo Rubin and guides him toward Xuanyuan-related clues while secretly learning his methods and implanting safeguards. Each recognizes the other's utility, but neither mistakes utility for trust. (Chapters 963–1057, 1332–1370)

Li Ping

Li Ping first meets Mo Rubin as an opponent and tracker, then becomes his temporary Dark Sea partner. Their strengths are complementary: Li Ping supplies formation execution and source power, while Mo Rubin supplies diagrams and ancient authority. Mo Rubin refuses the Holy Emperor's attempt to convert common purpose into lasting allegiance, yet Li Ping concludes that this native Dharma King may still help when Xuanhuang faces its decisive crisis. (Chapters 1274–1279)

Heavenly Doctor

The Heavenly Doctor is an obstacle whose golden threads and needles can directly contest Mo Rubin's allegedly undying souls. Mo Rubin dismisses the Doctor's origins, but the High Wall clash demonstrates that disdain does not equal superiority: he needs his mirror, repeated demon-soul reassertion, and Li Fan's formation delay merely to reach the breach. Their opposed control techniques reveal both the resilience and the limits of the Demon Heart art. (Chapters 1363, 1367)

Xu Ke and Xing Wuque

Xu Ke inherits the underground Dark River mission left by Xing Wuque, one of Mo Rubin's fellow Dharma Kings. Learning that Xing Wuque carried out a single order for ten thousand years forces Mo Rubin to confront a kind of loyalty even he had not expected. Xu Ke's similar resolve persuades him that the old mission still has a living successor and strengthens his belief that Xuanyuan's preparations remain active. (Chapters 1368–1370)

Items

• Tianxuan Mirror: The transformed Xuantian Treasure Mirror is Mo Rubin's principal objective during his Alliance infiltration. He regards it as the best means of locating Xuanyuan and helps free it, but it is an autonomous heavenly treasure rather than his secure possession. (Chapters 965–1057)
• Ink-Stained Evil Tome: A pitch-black metallic book held by Mo Rubin and lent to the false Sun Xingwang. Its black light contaminates and suppresses artifact spirits, while the pollution must be purified by the surrounding world. It leaves Mo Rubin's custody when he lends it to Li Fan. (Chapters 989–993)
• White jade flagpole: A second-hand protective device used to maintain a shrinking zone of safety against Dark Sea erosion. Mo Rubin criticizes its condition; the text establishes use, not permanent ownership or later custody. (Chapters 1277–1278)
• Azure Firmament Pearl: Xuanyuan's supreme treasure becomes a trail Mo Rubin and Li Fan investigate near the Fishing Pond and Dark River. It is a clue to the King's arrangements, not an item in Mo Rubin's possession. (Chapters 1367–1370)
