Saint Gu-jung — Nano Machine

Saint Gu-jung is the humble former head of Shaolin who prevents a northern war through a decades-long rivalry with Chun Inji, then sacrifices his freedom in an attempt to infiltrate the Blade God faction.

Biography

Rivalry that became peace

About fifty years before the present conflict, Gu-jung is Shaolin's “enlightened one,” a respected but publicly understated leader. When the newly ascended Chun Inji tries to push the Demonic Cult north into Henan, Gu-jung meets him with ten disciples and the one hundred eight Hanjin. He defeats a prodigy who has passed all six academy tests, then proposes that future disputes be settled by personal contests rather than repeated movements of armies. At Inji's insistence they meet every five years. Gu-jung wins their first four rematches because he continues training as hard as the challenger who wants to surpass him. (Chapter 435)

Inji finally wins their fifth contest, but twenty-five years of rivalry have changed the reason for fighting. Mutual respect has become friendship, and Inji abandons his northern campaign rather than exploit the victory against Gu-jung's people. Gu-jung's achievement is therefore political as well as martial: without public office or a treaty, his strength, restraint, and willingness to risk himself avert a wider war between Shaolin's sphere and the Demonic Cult. (Chapter 435)

Eun Jarim and the Blade God descendants

Gu-jung secretly belongs to Eun Jarim, an organization formed from great Wulin clans to find and block the Blade God's descendants. When one of its operatives disappears near Mt. Biam, Gu-jung goes searching and encounters the revived enemy. Inji, who has been waiting for their scheduled match, follows the traces and finds Gu-jung struggling against an unknown master after his accompanying monks have been killed. The two old rivals combine their techniques to win. At Gu-jung's request, they take some enemies alive instead of killing everyone, because he needs prisoners and intelligence more than vengeance. Only afterward does he reveal Eun Jarim's existence and ask Inji to help carry the captives back to its base. (Chapters 435–436)

Evidence from the prisoners shows that the enemy can suppress a victim's will through a worm affecting the brain. Gu-jung permits examination of a dead operative, helping establish that the contracted brain and foreign influence—not ordinary betrayal—explain the controlled bodies. He and Inji spend years preparing a counter-operation, then deliberately pretend to be subdued so they can enter the Blade God faction's base. Their strong sense of duty survives initial persuasion, threats, and torture, but the captors close their internal-energy circulation and break them down over ten years. Inji later concludes that Gu-jung suffers the same fading windows of awareness he experiences as the worm adapts to their resistance. (Chapters 436–437)

The masked Spirit Squad

Eighteen years after Gu-jung disappears, he returns inside the Blade God faction's Spirit Squad wearing an iron mask. When the mask cracks, Moyong Kang recognizes his white hair, wrinkled face, and six forehead seals. Gu-jung no longer responds to his old acquaintance; his eyes are blank, he attacks with Shaolin Dragon Tide, and he moves toward Yeowun as though an implanted order has reduced his mind to a single target. Witnesses initially wonder whether a revered saint has “lost his way,” but Inji's later account reframes the scene as the final consequence of their failed infiltration rather than voluntary allegiance. (Chapters 424–425, 434–437)

Yeowun kills many masked Spirit Squad members during the Dragon Turtle battle, and Inji later says Gu-jung and the others were sacrificed because of his plan. The text does not isolate Gu-jung's exact death blow, so his fate is best treated as presumed death in that battle rather than a witnessed individual execution. His legacy remains active: Gak-yeon is regarded as the only later Shaolin monk notable enough to inherit his position, and Inji asks that Shaolin's people be spared because they belong to his old friend's temple. (Chapters 425, 434, 442, 448)

Appearance and personality

Gu-jung is an old man with messy white hair, a deeply wrinkled face, and six seals on his forehead. Before his captivity he is remembered as good-natured, humble despite exceptional strength, devoted to justice, and willing to turn an enemy into a friend to prevent casualties. His choice to spare prisoners and infiltrate their organization shows patience and duty, but also leads to catastrophic overconfidence in how long he and Inji can resist. The blank, unresponsive masked fighter seen later is not a reliable expression of his personality.

Martial arts and abilities

Martial level and Shaolin foundation

Gu-jung's martial ability is described as equivalent to the Five Strongest Warriors. He knows roughly half of Shaolin's seventy-two rites, a broad foundation rather than one isolated specialty, and is strong enough to defeat the six-test graduate Chun Inji in four consecutive five-year contests. The fifth contest finally goes to Inji after decades of mutual training. This progression establishes Gu-jung as an elite but not static or invincible master: his rival eventually surpasses him, and even their combined techniques require a long struggle against the Blade God descendants. (Chapters 424, 435)

Shaolin Dragon Tide

The only personal technique explicitly named during Gu-jung's present-day appearance is Shaolin Dragon Tide. He unfolds it with his hands and gathers energy into his fists before closing distance. In his controlled state, the art remains physically available even though recognition, judgment, and independent target selection appear absent. The chapters demonstrate its hand-based deployment but do not explain its full sequence, range, or energy cost. (Chapter 424)

Combined combat and tactical restraint

Gu-jung and Inji begin with foundational techniques and escalate through every method they can use against the unknown Blade God master. Their cooperation eventually wins despite the enemy's extreme blade art. Gu-jung then prevents Inji from killing every defeated opponent so they can obtain information. This choice shows how his fighting skill interacts with a broader mission: victory is a means to investigate and contain the Blade God lineage, not merely defeat an individual. (Chapter 435)

Mental resistance and its limits

Gu-jung enters captivity intending to fake submission, but the enemy blocks internal-energy flow, tortures the infiltrators for years, and uses a worm that suppresses the host's will. Inji can briefly recover awareness through Reverse Health Preservation before the worm adapts; he believes Gu-jung faces the same process. By the Dragon Turtle battle, Gu-jung retains cultivated energy and Shaolin forms but displays blank eyes, no recognition of Moyong Kang, and fixation on the assigned target. The source does not demonstrate that he can activate the same resistance or regain a conscious interval. His case therefore distinguishes preserved martial memory from personal control. (Chapters 424, 436–437)

Relationships

Chun Inji: His sworn ally and partner in the infiltration.
Gak-yeon: The Shaolin successor judged most notable after Gu-jung.
Moyong Kang: An old acquaintance who recognizes Gu-jung beneath the mask but cannot reach his suppressed personality.

Items

Iron mask: Conceals Gu-jung as a Spirit Squad combatant until it cracks during battle. It is an identifier and uniform, not the demonstrated source of his control. (Chapters 424–425)
