Lin

Lin is a red-dragon-descended draconian, Fairy Garden's vice-guild master, and a master craftsman whose equipment repeatedly prepares Kang Shin for threats beyond the dungeon's normal scale. His gruff work as a Floor Shop administrator develops into direct mentorship, combat against a world enemy, and quiet opposition to the system that binds the administrative guilds. (Chapters 64, 93, 199–200, 234–240, and 320–331)

Biography

Field Dungeons and Revival

Lin meets Shin while temporarily operating a Floor Shop in Loretta's place. He introduces himself with little ceremony, explains that his draconic bloodline makes him different from a beastman, and immediately tests the new explorer through a wager: Shin must clear successive Floor Masters alone and within increasingly short deadlines to earn custom equipment. The contest reflects Lin's contempt for explorers who surrender to safe stagnation. When Shin answers that he also hates giving up, their outwardly antagonistic friendship begins around a shared respect for perseverance. (Chapter 64)

The wager makes Lin both examiner and practical instructor. He restricts Shin from using parties for the designated bosses, provides carefully incomplete hints, and explains mechanics such as resistance to mental attacks and the way boss rewards compare performance with an explorer's true capacity. He also turns a Blood Succubus corpse into a direct mental-defense item rather than letting Shin rely on statistics alone. Shin's first-attempt victory over the Grim Reaper completes the challenge in only three months, forcing Lin to honor the bet with the Crimson Dragon equipment he had already prepared. (Chapters 66, 68, 79, 86, 88, and 93)

Lin's craftsmanship soon extends beyond the wager. He rebuilds Edward Walker's damaged guardian bracelet from its surviving core and First Dungeon materials, producing a stronger version while preserving its binding to Walker. Shin thereafter brings him Mana Stones, corpses, and damaged equipment because Lin can identify uses ordinary markets cannot. Although Lin disguises concern with fees, insults, and complaints, his willingness to modify dangerous materials around the wearer's actual needs establishes him as one of the people Shin trusts when generic dungeon rewards are insufficient. (Chapters 93, 98, 119, and 130)

World Crises and Heroic Growth

When Shin discovers that monsters serving Luka's Demon Lord are also appearing on Earth, Lin supplies the diagnosis that Loretta initially cannot voice: Earth is suffering a Double Crisis, with two invading forces sharing and widening the dimensional pathway. His explanation turns a collection of anomalous encounters into a two-year existential deadline. He then accepts the remains of a Demon Army Commander and other high-grade monsters to replace Shin's aging gear, despite recognizing the risk and workload. His cold assessment and practical response make him more than a shopkeeper; he becomes part of Shin's preparation for enemies that can exceed the dungeon's assumptions. (Chapters 165–166)

The resulting Pure Black Desire armor and upgraded cape display both Lin's skill and his caution. He creates Legend-grade equipment whose offensive effects can trade the wearer's health for greater damage or absorb a target's vitality, then explicitly warns that the armor's demonic materials can mutate an incautious user. He also outfits Revival's succubus units with uniform robes that preserve mobility while giving the force an organized public identity. These projects show his progression from rewarding one explorer's climb to equipping a world-defense organization, even though he continues to insist that he works for Loretta rather than for Shin. (Chapters 182, 199–200, and 213)

Guardians and World Enemies

The disappearance of the administrative guild master Sipua forces Lin out of his workshop. The First Dungeon cannot operate without all five guild masters, and the administrative members can travel to other worlds only under strict conditions, so Lin accompanies Shin and Daisy Ectradion to the conquered Sylon continent. The mission exposes his own position: the administrators are failed Heroes who accepted the dungeon's binding to help later defenders, and Lin has subordinated his desire to destroy world enemies to that collective purpose. He treats Sipua's abandonment not merely as desertion but as betrayal of thousands of years of shared sacrifice. (Chapters 234–237)

On Sylon, Lin demonstrates power he deliberately keeps hidden. He kills elite Book Walkers with mana-strengthened handguns, changes tactics before their shared records can build resistance, and reserves an ancient sniper rifle for the enemy commanding them. Shin and Lin plan around Caduceus: Lin allows himself to be killed, is revived within the skill's narrow window, conceals his presence, and fires only after Shin restrains the overconfident world enemy. The shot destroys its head in one attack. His willingness to make his own death part of the plan shows the discipline beneath his casual arrogance, while the secrecy of the rifle prevents the Book Walkers from adapting beforehand. (Chapters 236–239)

Sipua and Hydelcyon's collaboration with that enemy provokes Lin's harshest response. He prevents Sipua's magic with a wall of fire, lets the Sylon dead punish Hydelcyon, and prepares to kill Sipua while taking her administrative burden onto himself. Shin instead forces her back into service through absolute obedience, sparing Lin an additional binding but leaving both men disturbed by the result. Loretta later condemns Lin for risking himself and Shin, yet also reveals her fear of losing him. The incident strengthens Lin's investment in a successor capable of ending the cycle rather than merely preserving the dungeon indefinitely. (Chapters 239–241)

Afterward, Lin's work increasingly helps people function when dungeon support is suppressed. The accessory Shin names Radiance supports him in the Peruta Mountain Range, where ordinary explorer powers are weakened, and a paired bracelet is later given to Daisy. Lin also accepts the gun-wielding Leon Pepper as a student, alternating instruction with dungeon practice so that technique becomes embodied rather than remaining theoretical. His support thus expands from making equipment for Shin to preserving independent combat paths for other Revival members. (Chapters 241, 254, 270–280)

Final Wave and the Dungeon's End

Lin's desire to escape the dungeon's influence becomes explicit in the evolution of Pure Black Desire. He modifies the armor so Eleine's reinforcement artifact will activate only after it accumulates sufficient battle experience, but neither craftsman predicts the extraordinary materials the process will consume. When the armor is finally shattered, it absorbs demonic bodies, a continent-scale spell, mana, and world power before becoming the semi-living Steel. Lin identifies its single authority, Extort, explains that it reflects or steals only from targets below its user's league, and recognizes that the new creation is no longer readable or governed by Sherafina's item system. (Chapters 277 and 320–323)

That result changes how Lin describes his profession. He argues that the greatest ancient artifacts possess “Ambience”: a decisive identity born from an unrepeatable convergence of creator, wielder, materials, history, and miracle rather than a collection of dungeon-assigned options. Steel is the first new Original he has seen in a long time, and his own hidden sniper rifle belongs to the same category. The theory is presented as Lin's interpretation of how Sherafina assigns ranks, not as a fully confirmed universal law, but it reveals why he values a creation that exceeds both his plans and the Dungeon Lord's appraisal. (Chapters 322–323)

Lin remains involved through Shin's last preparations. He cooperates with Eleine to resolve the Chaotic Spear's incomplete digestion and contributes his mana and craftsmanship to its final, unappraisable platinum evolution. By the conclusion, Loretta says Lin recognized Sherafina's plan earlier than she did and recalls that he once wanted the Collector's Pocket Watch because he believed it could defeat the Dungeon Lord. Sherafina's defeat allows Shin to begin dismantling the dungeon and freeing the administrators bound to it, leaving Lin alive and on the verge of the release his independent creations had long anticipated. (Chapters 331 and 352)

Appearance and personality

Lin is a handsome, slender man with very long black hair tied in a high ponytail. Curled silver horns emerge symmetrically from his temples, and a heavy scaled tail makes his draconic ancestry unmistakable once noticed. He commonly wears loose black clothing suited to the heat of his forge and almost always has a cigarette, which he can ignite or erase with fire. On the Sylon mission, he changes into close-fitting leather gear carrying twin handguns and a concealed long black sniper rifle. (Chapters 64, 199, and 234–239)

He is abrasive, teasing, and intensely proud of his craft, often demanding payment or pretending that favors are obligations imposed by Loretta. The pose is transparent to people who know him: he prepares rewards before admitting Shin has won, works on equipment for people he respects, and takes satisfaction when a creation exceeds its materials. Lin values persistence and loyalty, reacts severely to betrayal, and can be reckless when those principles are violated. His humor and constant bickering coexist with sober judgment about equipment risks, world enemies, and the dungeon's hidden constraints. (Chapters 64, 86–93, 166, 199–200, and 239–241)

Powers and abilities

Lin combines a red-dragon bloodline, high-level mana control, firearms strengthened by personal authority, and craftsmanship capable of producing equipment beyond standard dungeon rewards. His latest work deliberately reduces dependence on Sherafina's system, but the corpus never supplies a numerical level, complete list of skills, or exact limit for his fire and forging output. (Chapters 64, 166, 199–200, 234–241, and 320–331)

Draconic bloodline and flame

As a draconian descended from a red dragon, Lin has horns, a scaled tail, and a natural affinity for fire. He can ignite objects without a lighter, breathe flame directly during fine metalwork, produce fireballs, and raise a wall of heat strong enough to cancel Sipua's spell and make nearby combatants struggle to breathe. His crimson mana can also examine a finished artifact by contact. The story does not establish a named transformation, breath attack, or quantified resistance for him, so broader dragon abilities should not be assumed from ancestry alone. (Chapters 64, 232, 237, 239, and 322)

His fire is equally a tool of precision and force. In the workshop, controlled breath refines a ring after its basic form is complete; in battle, a foot movement raises a containing wall and a later ignition erases hundreds of undead remains without ash. Darkness magic on Sylon can make even creating a small flame difficult, demonstrating that his affinity can be environmentally suppressed. He nevertheless remains physically and magically formidable enough that the dungeon would be endangered by losing him, though the source does not define whether that importance comes from combat, maintenance work, or both. (Chapters 232, 237, 239, and 254)

Smithing, appraisal, and equipment design

Lin designs equipment around the user, available materials, and a desired combat function rather than merely raising its rank. He combines monster remains with existing gear, repairs bound artifacts without breaking ownership, inscribes gems, upgrades clothing for large units, and compresses armor into bracelet forms that deploy when mana is supplied. Pure Black Desire demonstrates the method's danger: demonic material provides powerful vitality-stealing and attack-amplifying effects, but Lin warns that uncontrolled absorption can mutate its wearer. His work therefore includes explaining activation conditions, failure risks, and counters, not just producing strong objects. (Chapters 86–98, 166, and 199–200)

He can also interpret artifacts he did not create. With Eleine's reinforcement tool, Lin identifies requirements invisible to ordinary appraisal: the target needs sufficient league and must accumulate a record of protecting its owner through varied battles. He modifies Pure Black Desire to signal when those conditions are met, but he cannot predict the final process or fully explain Steel afterward. His analysis of Extort identifies its dependence on the user's comparative league and its potential to grow with that user. These limits distinguish expert diagnosis from omniscience; truly original artifacts can exceed even their craftsman's plan. (Chapters 277 and 320–323)

Lin's later spear work likewise combines correction with collaboration. He notices that the Gluttony Spear's evolution into Chaotic Spear wasted absorbed energy and retained too much of his own fire attribute, then secures a magical bead from Eleine to complete the next change cleanly. The evolution requires Lin and Shin to contribute an enormous volume of mana, and its resulting platinum form cannot be appraised through the dungeon. This is his latest demonstrated creation work and another example of a product becoming greater than a predefined list of material effects. (Chapter 331)

Mana-enhanced firearms and the ancient rifle

Lin comes from a scientifically advanced world whose guns resemble Earth's, but he can strengthen both weapon and ammunition with mana. His twin handguns fire rapidly, never miss in the shown engagement, and kill elite Book Walkers with one shot until their shared observation begins generating resistance. Because those enemies distribute records of attacks across their species, he and Daisy must eliminate observers quickly and vary their approach. The handguns are therefore devastating against unprepared targets but not a universal answer to adaptive enemies. (Chapters 234 and 236)

His sniper rifle is an ancient Original carrying a far greater concentration of his power and authority. Lin keeps its existence secret from almost everyone, accepts temporary death to preserve that secrecy, and fires after Shin immobilizes the Sylon world enemy. The single bullet destroys the target's head despite its overwhelming strength. Lin later uses the rifle to explain Ambience, the decisive quality he believes separates miracle-born Originals from derivative equipment. The precise authority, ammunition cost, firing limits, and whether it could repeat that result against a prepared equal are not stated. (Chapters 234, 238–239, and 323)

Administrative knowledge and instruction

As a Fairy Garden administrator, Lin understands dungeon rewards, comparative achievement, mental defense, gods' true names, the effects of world crises, and the restrictions on administrative guild travel. He uses this knowledge selectively, often forcing Shin to discover an answer through a boss challenge instead of supplying it outright. He is not all-knowing: several advanced artifacts surprise him, and his account of item ranks is explicitly his own theory based on observing Sherafina's judgments. His instruction is most reliable when grounded in mechanics he has tested through crafting or combat. (Chapters 64, 86–93, 165–166, 234–236, and 320–323)

With Leon, Lin applies a cycle of explanation and field experience, sending the gun user back into the dungeon whenever a newly taught principle needs to become practical skill. He judges Leon's character and potential highly while still comparing him unfavorably with Shin's exceptional growth. Lin's latest intellectual role extends further: he detects Sherafina's hidden plan before Loretta and had previously identified the Collector's Pocket Watch as a possible weapon against her. The source does not show exactly when or through what clue he reached that conclusion. (Chapters 280, 309, 322–323, and 352)

Relationships

• Kang Shin: Lin begins by betting against Shin's dungeon pace, then becomes one of his most trusted mentors and makers. Their insults conceal mutual confidence: Shin brings him irreplaceable materials and accepts his warnings, while Lin risks death beside him, builds equipment outside Sherafina's control, and helps complete his final spear. (Chapters 64–98, 165–200, 234–241, and 320–331)
• Loretta: Lin addresses Loretta as an elder and serves as Fairy Garden's vice-guild master under her authority. He complains about her demands but makes equipment for people she protects, shares her responsibility for the dungeon, and is one of the few administrators she openly fears losing. Both eventually recognize Sherafina's plan, with Lin reaching that suspicion first. (Chapters 64, 165–166, 199–200, 234–241, and 352)
• Daisy Ectradion: Daisy accompanies Lin on the Sylon mission and initially treats his draconic horns more like an animal feature than a dignity. Their teasing develops into effective cooperation: her knowledge and darkness magic deny Book Walkers information, while his firearms exploit the opening and kill their leader. Lin later creates a Radiance bracelet that she absorbs. (Chapters 235–241 and 277)
• Eleine: Eleine openly pursues Lin, while he maintains boundaries around Loka's pregnancy and treats her technical ability more seriously after studying her reinforcement artifact. Their collaboration helps evolve Pure Black Desire and later resolves the Chaotic Spear's flawed development. (Chapters 165–166, 277, 320–323, and 331)
• Leon Pepper: Shin entrusts Leon to Lin because both empower firearms with mana. Lin teaches him in the workshop, sends him into the dungeon to embody each lesson, and ultimately praises both his talent and character. (Chapters 277, 280, 309, and 322–323)
• Sherafina: Lin serves within Sherafina's dungeon but seeks to make equipment independent of her influence. He notices her concealed plan, believes the Collector's Pocket Watch could defeat her, and creates artifacts her appraisal cannot read, yet remains bound to the administrative system until Shin begins dismantling it after her defeat. (Chapters 234–241, 320–331, and 352)

Items

• Crimson Dragon equipment: Lin's reward for Shin's solo-clear wager, including red scale armor and a spear shaped around the explorer's fighting style. (Chapter 93)
• Pure Black Desire: Legend-grade armor forged from demon and monster remains; its powerful sacrificial and vitality-stealing effects carry risks that Lin explicitly warns Shin to manage. (Chapters 199–200)
• Radiance: An accessory made for Shin that continues supporting him where dungeon-derived power is suppressed; Lin also creates a counterpart later given to Daisy. (Chapters 241 and 270–277)
• Ancient sniper rifle: Lin's concealed Original and decisive weapon against the Sylon world enemy. Its complete origin and operating authority remain unknown. (Chapters 234 and 238–239)
• Steel and the platinum spear: Lin helps prepare the conditions for Pure Black Desire's evolution into Steel and later guides the final evolution of Shin's spear, although both results surpass normal appraisal and part of his own prediction. (Chapters 320–323 and 331)
