All the demons in the reception room stared at Russell with expressions ranging from confusion to growing alarm. The voice that had emerged from the supposed butler carried undertones that seemed to resonate from some darkness, making the elegant chamber's air feel thick and oppressive with barely contained malevolence.
All except the ancient Ancestor, whose shrewd eyes had sharpened with sudden, terrible understanding.
"You are not Winston, the butler of the Boar Clan," the elderly demon stated in a voice that had dropped to a low, dangerous growl. The words carried the weight of absolute certainty and dawning recognition of the magnitude of deception that had been perpetrated within their most secure sanctuary.
Russell's body began to writhe and shift with wet, organic sounds that filled the reception hall with an atmosphere of creeping horror. The careful disguise of Winston the butler melted away like wax under flame, revealing the tall, imposing figure that was Russell's true form. Bones cracked and reformed, muscles stretched into new configurations, and the familiar features of the trusted servant dissolved to expose something far more alien and dangerous.
Beside him, his full retinue of cards materialized from thin air with crisp efficiency, each summoned form taking shape with deadly precision. Lily appeared in her pristine white dress and gleaming armor, the legendary sword already beginning to pulse with contained radiance. Unohana manifested in her captain's haori, serene composure intact despite the hostile environment. Others took form around Russell like a constellation of barely contained power.
All the demons present fell into stunned, absolute silence as they processed the scope of infiltration that had been achieved right under their noses.
"You've been operating within our territory since the Grak incident, haven't you?" Although the Ancestor phrased his words as a question, his tone carried the iron certainty of someone who had already connected the dots. Without waiting for Russell's confirmation, the ancient demon turned his burning gaze toward the cowering father and son of the Boar Clan. "If it weren't for you two imbeciles and your pathological need for internal power struggles, I doubt he would ever have been exposed."
The revelation hit the elderly demon with the force of a physical blow. He had originally believed that the matter of the eliminated patrol guards had been cleanly resolved through the Boar Clan's unauthorized execution. But now it became crystal clear that his opponent's infiltration and disguise capabilities were far beyond anything he had imagined possible.
In what couldn't have been more than a few days, this outside creature had successfully assumed at least three completely different identities—patrol member, butler, and probably others they hadn't even discovered yet. He had moved through their society with such skill that even their most paranoid security measures had been completely bypassed.
The Boar Clan Patriarch and his son exchanged horrified glances, their minds struggling to comprehend how their petty scheming had led to such a catastrophic security breach. The Young Master's face had gone deathly pale as a particularly terrifying realization struck him like lightning.
He now understood with crystal clarity that either of the two subordinates who had reported back to his study had been replaced by this creature standing before them. Given the overwhelming aura of menace and power that Russell was now radiating energy that seemed to press against the chamber walls like a living thing it was obvious that if the infiltrator had chosen to eliminate him during their private meeting, resistance would have been utterly impossible.
The thought sent ice through his veins. He had been alone in a room with death incarnate and had been completely oblivious to the danger.
The Ancestor's ancient eyes narrowed to thin slits as he studied Russell's transformed appearance, his strategic mind already calculating possibilities and countermeasures despite the overwhelming disadvantage he now faced.
"So it is you and your kind," he said with barely controlled fury that had been building over decades of frustration. "A group of those accursed outsider creatures we've heard so much about." His voice carried generations of accumulated hatred and bitter experience. "But tell me..." His tone shifted to something approaching mockery despite the danger. "Are you truly arrogant enough to believe you can face all of us alone?!"
As his final words rang through the reception hall with the force of a battle cry, every demon present launched themselves into coordinated assault. The air itself seemed to catch fire as magical energies erupted from multiple sources simultaneously devastating flame spells, crushing lightning bolts, force projectiles capable of shattering mountains, and exotic magical effects that defied easy categorization.
A terrifying wave of destructive power exploded from within the Boar Clan's underground mansion, shaking the very foundations of the mountain itself and sending tremors through hundreds of meters of solid rock.
Unfortunately for the attacking demons, they had severely underestimated both their opponent's capabilities and his preparation for exactly this scenario.
"Bakudō #81: Dankū!"
Unohana's voice carried clearly through the chaos . The spell she cast was among the most powerful defensive techniques in her extensive arsenal.
A transparent, shimmering barrier materialized instantly in front of Russell and his summoned cards. Its surface gleamed like polished crystal shot through with veins of pure energy, and despite its ethereal appearance, it possessed defensive capabilities that bordered on the absolute.
The concentrated magical assault struck the barrier with tremendous force—enough raw power to obliterate entire military formations—but the translucent wall remained completely motionless. Every spell, every projected attack, every manifestation of demonic fury broke against its surface like ocean waves against an immovable cliff. The barrier stood firm as divine protection, earning its reputation as an impenetrable ward that had never been breached by conventional magical assault.
The Ancestor's pupils contracted with shock and rapidly mounting dread as he witnessed the effortless negation of their coordinated attack. "This kind of defense..." The sight brought back memories he had tried desperately to forget dark days when their people had first encountered these outside creatures and learned the true meaning of helplessness.
Before their current exile to this underground refuge, their civilization hadn't been reduced to the scattered remnants it was now. They had been a proud and powerful race with established territories, significant magical capabilities, and military forces that had dominated their region for millennia. But these creatures from the outside world had proven to be completely unlike anything they had faced in previous conflicts.
Their abilities were strange and comprehensive, often requiring several of the tribe's strongest warriors working in perfect coordination just to match a single outside invader. The disparity in capabilities was so vast that it often seemed like they were fighting beings from an entirely different category of existence.
"Attack with everything you possess!" the Ancestor shouted with desperate urgency, his voice cracking under the strain of commanding what he knew might be their final battle. "We must contain him here at all costs, no matter the sacrifice required!"
But even as he issued these commands, Russell's expression had shifted to something far more predatory and anticipatory. A malicious smile spread across his features as he looked at the assembled demons with the satisfied anticipation of someone about to reveal their trump card.
"I've been patiently waiting for you to exhaust your opening moves," he said with dark amusement that made several demons flinch involuntarily. "What exactly are you waiting for now?"
Before the Ancestor could process the ominous implications of that statement, the petite figure beside Russell had already raised the beautiful sword in her small hands. The blade seemed to pulse with internal starlight, its surface reflecting illumination that came from no external source but rather from the legendary power contained within its very essence.
All present could feel the air itself begin to vibrate with potential energy as Lily prepared to unleash one of the most devastating attacks known to exist in any realm.
"CALIBURN!" Her voice rang out with crystalline clarity that somehow carried across dimensions, the name of the legendary sword resonating with power that made reality itself seem to bend in acknowledgment.
A massive golden beam of light suddenly erupted from the sword with the concentrated fury of a dying star. The radiance was so intense that it temporarily blinded every demon in the reception hall, their enhanced vision unable to process the sheer luminosity of an attack that channeled the essence of solar fire itself.
The beam pierced straight upward with unstoppable force, punching through the ceiling of the underground space as if the tons of solid rock above were no more substantial than morning mist. The terrifying destructive power carved through layer after layer of stone and earth with casual ease, creating a perfectly circular tunnel that reached toward the surface world far above their heads.
The entire mountain began to shake and tremble as structural supports that had stood for centuries simply ceased to exist. Load-bearing elements were vaporized by the golden radiance, causing chain reactions of collapse throughout the underground complex. The sound was indescribable—part earthquake, part explosion, part something else entirely that human language had no words to capture.
"Quick! Stop her before she brings down the entire mountain!" The words that emerged from the Ancestor's mouth were so distorted by panic and desperation that they barely resembled normal speech. His voice cracked under the strain of issuing commands while witnessing the systematic destruction of everything his people had built.
The demons around him weren't fools they understood immediately that allowing this devastation to continue would mean the complete collapse of their hidden sanctuary and the burial of everyone within under millions of tons of rubble. Unfortunately for them, understanding the problem and being capable of solving it were entirely different matters.
How could a collection of demons whose silver-level status was more political than practical hope to stop the Golden Sword of the Victorious when it was wielded by someone of Lily's legendary capabilities? Even demon lords who had ruled for millennia had been completely annihilated by the terrifying power of this mythical weapon.
The golden beam continued its devastating arc, carving downward through the reception hall with methodical precision that spoke to perfect control despite the weapon's overwhelming destructive potential. It left a horrific, molten scar across the ceiling of the underground space, the edges of the cut glowing with residual energy that spoke to temperatures capable of vaporizing steel instantly.
The demons could only watch in helpless horror as their sanctuary was systematically destroyed before their eyes. They were powerless to intervene against such overwhelming force, reduced to the role of witnesses to their own civilization's destruction.
The blazing heat that accompanied the sword's passage instantly annihilated everything in the beam's direct path. Expensive furniture became ash in milliseconds. Decorative elements carved from precious stone simply ceased to exist. Even the air itself seemed to burn in the wake of Lily's attack, creating a column of superheated atmosphere that would remain lethally hot for hours after the weapon's energy dissipated.
After what felt like an eternity but was probably only seconds of sustained destruction, the golden radiance finally began to fade. As the blinding afterimages cleared from everyone's vision and the ringing in their ears subsided enough to allow coherent thought, the true scope of the devastation became apparent.
Where moments before there had been an elegant reception hall filled with the most powerful leaders of the underground society, now there was only destruction and death on an almost incomprehensible scale. Dozens of charred demon corpses lay scattered across the ruined floor, their forms barely recognizable as having once been living beings.
The lucky ones had been killed instantly by the initial blast of heat, their deaths too quick for suffering. Others showed signs of having survived just long enough to experience the full horror of their situation before succumbing to injuries that no healing magic could address.
Only one figure remained alive amid the carnage—the ancient Ancestor who had orchestrated this final confrontation. His clothes were torn and smoking, revealing severe burns across most of his body. Blood seeped from multiple wounds, creating dark stains on the scorched stone floor as his life slowly leaked away.
"You're still breathing?" Russell observed with genuine surprise tinged by professional admiration as he studied the elderly demon's battered form. "That's actually quite impressive, considering what you just survived."
The Ancestor opened his mouth and released a substantial quantity of blood before managing to speak. His voice was barely above a whisper, but it still carried traces of the authority he had wielded for so many centuries.
Russell's mind immediately began analyzing the situation with cold precision. "It must be some form of special life-saving ability," he concluded after a moment of consideration. There was absolutely no way the ancient demon could have survived Lily's concentrated assault through natural resilience alone not when beings significantly more powerful than him had been reduced to charcoal by similar strikes.
The ability was probably some form of damage transference or death substitution, allowing the user to sacrifice valuable resources or prepared contingencies to survive otherwise lethal attacks. Such techniques were rare and expensive to maintain, but they could turn the tide of battles that would otherwise end in certain death.
"Perfect opportunity to finish what we started," Russell decided with cold pragmatism.
He was preparing to have Unohana deliver a finishing Black Coffin spell when his expression suddenly shifted to one of alert concern. After revealing himself and engaging in open magical combat, he had extended his mental perception to its maximum range to monitor for additional threats or reinforcements.
Now, at the very edge of his enhanced awareness, he detected several powerful magical signatures moving rapidly toward their current location. The approaching auras were strong enough to register clearly despite the distance, suggesting silver-level entities or possibly something even more dangerous.
Russell's thoughts flashed through calculations . After directing Lily to collect the valuable materials that could be extracted from the deceased demons' remains a process that took only moments thanks to her supernatural efficiency he made the strategic decision to withdraw rather than risk a prolonged engagement against unknown opponents.
Who knows what other special abilities the Ancestor might have hidden away? Russell reasoned as he weighed his options. Now that Lily has temporarily expended Caliburn's ultimate attack, my available combat assets are reduced to myself and Unohana. I'm not prepared to gamble everything on the assumption that our enemies don't have additional trump cards.
Besides, Lily's legendary sword would be restored to full functionality within twenty-four hours. Much better to retreat now, allow his forces to recover completely, and return to deliver another devastating attack when circumstances were more favorable.
I make calculated decisions, and I make consistent profits, he reminded himself with satisfaction at his own thinking.
Having settled on this course of action, Russell accepted the thirteen portions of silver-grade materials that Lily had efficiently gathered from the fallen demons. The magical extraction process left behind only harmless ash while preserving the valuable essence that could be used for future card creation projects.
Then Russell extended the flesh wings that emerged from his transformed back, the membranous appendages unfurling with organic grace that spoke to Arrogance's perfect integration with his physiology. With powerful wingbeats that sent debris flying and created small whirlwinds in the ruined reception hall, he lifted himself and his summoned cards into the air.
Not long after Russell's departure, several new demons descended upon the site of devastation with the sharp whistle of high-speed aerial movement. Their expressions shifted from grim determination to absolute horror as they took in the scene of unprecedented destruction.
"Ancestor!" one cried out in dismay upon spotting the elderly demon's battered form among the carnage.
"What happened here?!" demanded another, his voice carrying the kind of shock that comes from witnessing something beyond normal comprehension.
"Who could have done such a thing?!" The questions overlapped in a chorus of disbelief and mounting panic.
Various inquiries and exclamations rang out simultaneously through what had once been the Boar Clan's elegant reception hall but was now nothing more than a smoking crater filled with evidence of supernatural violence.
The Ancestor was breathing heavily, each inhalation a visible struggle as his damaged lungs worked to process air that still carried traces of superheated energy. His pale hair hung in disheveled strands around his shoulders, and his eyes were bloodshot from the strain of surviving an attack that should have been instantly fatal.
"Creatures from the outside world," he managed to say in a voice made hoarse by smoke inhalation and internal injuries. "They infiltrated our sanctuary completely. This destruction was all their work." He gestured weakly toward the charred remains scattered across the floor. "Apart from myself, all the remaining family heads in our settlement are... here."
As he spoke these words, the full implications began to sink in for the newly arrived demons. The leadership structure of their entire underground society had been effectively decapitated in a single, devastating assault. Generations of political balance and careful alliance-building had been wiped out in moments.
The reinforcement demons couldn't help but display visible horror as they processed the magnitude of their losses. They had witnessed the golden beam of light from distant locations, but seeing its effects up close was an entirely different experience that challenged their understanding of what individual combatants could achieve.
Several of the demons felt profound gratitude that they hadn't been present in the settlement when the attack occurred. Otherwise, their fate would have been no different from the carbonized corpses scattered around them like gruesome decorations.
"Perhaps the enemy can't launch that type of attack multiple times in succession," one demon suggested with desperate hope that spoke to the psychological need to find some reason for optimism in their dire circumstances. "If they could strike continuously with such power, wouldn't they have pursued us and finished everyone off?"
The Ancestor's bitter smile ruthlessly shattered their wishful thinking before it could take root. "While it's true that they probably can't use that specific attack continuously, the opponents haven't expended much of their overall energy reserves." As an elder who had lived through the initial conflicts with outside creatures, he possessed knowledge that these younger silver-level demons lacked. "The reason why the beings from the outside world are so terrifyingly effective is that their unique ability system allows them to repeatedly deploy what we would consider ultimate techniques attacks that we can only use once before completely exhausting ourselves."
One of the demons absorbed this information with visible despair creeping across his features. "Then, Ancestor, what should we do now? How do we survive this?"
Blood continued to drip steadily from the elderly demon's temples as he stared at the hideous crack that Lily's sword had carved across the ceiling of their underground refuge. His voice carried the weight of final defeat when he replied:
"Wait for death. We had expected this day would eventually come, hadn't we?"
The words fell into the ruined chamber like stones into still water, creating ripples of despair that touched every demon present. After becoming servants to their mysterious patron, everyone should have been mentally prepared to sacrifice their lives when circumstances demanded it. But intellectual preparation and emotional acceptance were entirely different challenges.
"Our tribe's final struggle seems so pathetically inadequate in the face of attacks like that," the Ancestor continued, speaking more to himself than to his audience. "Although the outsider creature retreated out of apparent caution this time, I have no doubt they'll return very soon to finish what they started. They're simply being thorough rather than merciful."
All the demons fell into stunned silence as they absorbed their leader's hopeless assessment. They had never expected to hear such complete resignation from their most senior authority—the figure they had looked to for guidance and salvation in their darkest hours.
One demon gritted his teeth and spoke with desperate defiance that cut through the oppressive atmosphere: "I refuse to wait here to die like some sacrificial offering. I'm going to attempt an escape right now. There's always some small chance of survival if you keep moving and fighting."
Without waiting for permission or arguments from his companions, the demon launched himself into the air and flew rapidly in the direction he had come from, abandoning the settlement and his fellow survivors without a backward glance. His departure left a silence that somehow felt even heavier than before.
Meanwhile, Russell had traveled a considerable distance from the devastated settlement, taking a circuitous route through the underground cavern system that would prevent easy tracking of his movements. His destination was the massive metal gate he had observed during his initial reconnaissance the main entrance to the underground complex that served as both the primary defensive chokepoint and the most obvious escape route for any surviving demons.
What Russell planned to implement now was a classic tactical approach that military strategists called "catching turtles in a jar." By positioning himself at the main exit point, he could engage enemies with maximum advantage while maintaining the option to retreat if circumstances became unfavorable. Given his current capabilities and the demons' demonstrated weaknesses, controlling the metal gate represented the optimal approach for completing his remaining mission objectives.
The flight through the vast underground spaces gave Russell time to appreciate the true scope of what the demons had accomplished. These caverns stretched for kilometers in multiple directions, connected by a network of natural and artificial passages that spoke to decades or possibly centuries of careful engineering. It was less a simple refuge and more a complete underground civilization.
It didn't take long before Russell spotted his target from the air—the enormous metal portal with its intricate magical ward systems, still guarded by a contingent of demon troops who apparently hadn't yet received news of the catastrophe at the main settlement. The guards were maintaining their posts with professional discipline, unaware that their entire command structure had just been eliminated.
Russell's Arrogance-enhanced form twisted into a predatory smile as he prepared for the next phase of his assault. These defenders would provide an excellent opportunity to test some of his other capabilities while ensuring that no organized resistance could escape to warn potential allies in other locations.
"BOOM!"
The sound of Russell's landing carried across the gate area like thunder, his enhanced mass and velocity creating a significant crater in the stone floor directly in front of the metal portal. The impact sent shock waves rippling through the immediate area and caused several of the magical ward systems to flicker momentarily as their stability was disrupted.
"What's happening?!" shouted one of the guards as alarm bells began ringing throughout the defensive position.
"Enemy attack!" cried another as the reality of their situation became clear.
Chaotic voices erupted among the demon army as they scrambled to respond to this sudden and overwhelming threat. Within minutes, numerous bronze-level and iron-level demons had gathered in defensive formations, their training overriding their fear as they prepared to engage what they could see was a significantly superior opponent.
Creatures of various subspecies and clan affiliations stared up at the tall black and red monster standing before their most important defensive position. The sight of Russell in his full Arrogance form was genuinely terrifying—a being that seemed to exist at the intersection of nightmare and cosmic horror, radiating malevolent power that made the air itself feel thick and oppressive.
"It's one of those outside creatures!" a demon scout identified Russell's nature with rising panic in his voice that infected his nearby comrades.
"Several of our leaders went to the main settlement for an emergency meeting," another added with growing dread as he began to understand the implications. "Could something terrible have happened to them?"
But fear quickly transformed into desperate aggression as the defenders realized that retreat was impossible and surrender was not an option. Their families and everything they valued lay behind that gate, and failure here would mean the destruction of everything they had worked to preserve.
"Kill the invader!" The battle cry erupted from dozens of throats simultaneously as the demon army charged toward Russell with weapons raised and spells preparing to launch.
But Russell had chosen this location precisely because it offered him tactical advantages that his enemies couldn't match or counter. He had been waiting for the demons to gather in one convenient location where his specialized capabilities would be most effective, and he definitely had his reasons for such strategic patience.
"Kiss-Shot," he called out with calm confidence, using the nickname he had developed for one of his most versatile cards. "I'm entrusting this engagement to you."
From the shadows beside Russell, a graceful figure emerged with fluid movements that seemed to defy the normal rules of physics and motion. Blade Heart materialized with the kind of otherworldly beauty that was both alluring and deeply dangerous, her very presence seeming to bend light and shadow around her form.
It had been quite some time since Russell had deployed this particular summons in actual combat, and some observers might question the wisdom of using what appeared to be a support-focused entity against such large numbers of enemies. But those observers would be missing the crucial detail of Blade Heart's most devastating special ability:
[Demonic Charm]: Beings below iron-level cannot resist the supernatural allure of Blade Heart and will voluntarily sacrifice their lives for her attention and approval.
With the appearance of the elegant, deadly figure, the demon troops that had been charging toward Russell with murderous intent suddenly began to falter. The organized charge dissolved into chaos as individual demons found their attention captured by something they couldn't quite understand or resist—a compulsion that bypassed their rational minds and spoke directly to deeper instincts.
Many iron-level demons abruptly halted their advance and reversed the orientation of their weapons, turning blades that had been aimed at Russell toward themselves instead. Bloody suicide scenes began occurring across the battlefield as the charm effect overwhelmed their survival instincts entirely, replacing self-preservation with an overwhelming desire to please the beautiful entity that had appeared among them.
The carnage was both swift and comprehensive. Dozens of demons fell to self-inflicted wounds within moments, their last expressions showing not pain or regret but a kind of blissful satisfaction at having provided entertainment for Blade Heart's amusement.
Eventually, even some of the bronze-level demons with stronger willpower began to crack under the psychological pressure. Those who managed to resist the direct charm effect found themselves witnessing their comrades' mass self-destruction, an experience that shattered their morale and fighting spirit completely.
"Monster! Unnatural creature!" they screamed in terror, their voices breaking with the strain of confronting something that violated their understanding of how reality was supposed to function.
"I don't want to die here! I don't want to end like this!"
They dropped their weapons and fled toward the main settlement without looking back, abandoning their posts and their fallen comrades in desperate attempts to escape whatever supernatural influence had claimed so many of their allies.
Russell, currently wearing his Mark 3 armor for both enhanced protection and intimidation value, used the suit's integrated weapons systems to eliminate the fleeing demons with precise gunfire. The armor's targeting systems made such cleanup operations almost trivially easy, requiring minimal effort on his part.
It was only in secret realm environments like this that Russell could allow all his cards to operate at full capacity without worrying about collateral damage, civilian casualties, or political complications. Under normal circumstances back in New Metro, his spirit summons rarely had opportunities to demonstrate their true capabilities without creating problems that would attract unwanted official attention.
While Russell was systematically cleaning up the battlefield and collecting valuable materials from the fallen demons, his enhanced senses detected a new magical signature approaching the area. This one registered as significantly more powerful than the scattered troops they had just eliminated probably a silver-level entity drawn by the sounds of combat.
"Someone's actually approaching this obvious death trap," Russell observed with dark amusement as he prepared to engage yet another opponent.
A few minutes later, a demon wearing elaborate ceremonial armor appeared at the edge of Russell's field of vision. The newcomer took one comprehensive look at the scene spread out before the metal gate, and his face immediately went pale with shock and rapidly mounting horror.
Countless demons lay scattered across the ground in unnatural poses, their bodies bearing the distinctive wounds of self-inflicted death. The uniformity of their suicides created a surreal and deeply disturbing tableau that would have shaken even experienced warriors accustomed to witnessing battlefield violence.
"What do you think of the grave I've prepared for you?" Russell's voice carried across the silent battlefield like a whisper from the deepest pits of hell itself. The tone was casual, almost conversational, but it carried undertones that made the surviving demon's blood run cold.
The armored silver-level warrior spun around to locate the source of that terrifying voice and found himself staring at the tall black and red monster watching him with obvious interest and anticipation. Russell's expression suggested a predator that had found particularly entertaining prey.
"You deserve to die for this atrocity!" The demon's eyes blazed with fury and righteous indignation as he launched himself toward Russell in a desperate charge, his ceremonial armor gleaming as he moved with enhanced speed.
However, when he had covered approximately half the distance between them, another voice interrupted his attack with calm finality that spoke to absolute confidence in the outcome:
"Hadō #90: Kurohitsugi."
The pitch-black coffin materialized instantly around the charging demon's form, trapping him within Unohana's most devastating offensive spell before he could adjust his trajectory or attempt evasion. The dark energy that comprised the technique was specifically designed to inflict maximum damage while preventing escape or resistance.
When the shadowy construct finally dissipated several seconds later, the silver-level warrior was lying motionless on the scorched ground. His ornate armor had been cracked and twisted by forces beyond normal comprehension, and his body was covered in wounds that spoke to damage inflicted at the cellular level. Whether he remained alive was unclear, but he certainly wouldn't be participating in any further combat operations.
"Admirably brave, though ultimately foolish," Russell commented with professional appreciation for the demon's willingness to face overwhelming odds. "Unfortunately, you've entered a situation where arrival is permitted but departure is strictly forbidden."
These demons would probably never realize until their final moments that the underground space they had created to escape their enemies had now become a prison that would trap them until death claimed every remaining inhabitant.
Russell extended his mental perception across the now-silent battlefield, and moments later the valuable materials from the demon corpses began condensing into collectible forms. The process was both efficient and profitable, transforming the aftermath of battle into tangible resources that could be used for future projects.
"This is exactly the kind of problem I enjoy having," Russell muttered as he surveyed the substantial pile of materials that had accumulated from the mass casualties. Although most of the collected specimens were iron-grade and wouldn't be directly useful for his current power level, they still represented significant value for trading with younger students or converting to monetary resources through appropriate channels.
Unfortunately, his carrying capacity remained limited by the practical constraints of traveling without proper storage solutions. He had undertaken this mission with minimal equipment, not even bringing a basic storage pack for extended material collection operations.
After securing all the bronze and silver-grade materials, Russell selected the highest quality specimens from the iron-grade collection, prioritizing those with unique properties or rare characteristics that would be most valuable in future transactions.
"I must figure out how to create a storage card when I return to civilization," he decided with growing frustration at these logistical limitations. "But if you want to accumulate real wealth, you definitely need to visit secret realms that haven't been fully explored and controlled yet."
The iron and bronze materials Russell had harvested during this single operation were sufficient to purchase comfortable living accommodations in New Metro if converted to standard currency. However, he remained somewhat disappointed with the overall quality of the silver-grade materials, as they were predominantly blue or green quality rather than the gold-grade specimens he had hoped to find.
He estimated that only the most powerful demons in this particular realm would be capable of producing truly high-quality gold-grade materials. But Russell could understand the limitations—this was, after all, a secret realm designated for student practical training rather than serious exploration of unknown territories.
The presence of so many silver-level demons in his assigned area was actually beyond normal parameters for educational exercises. With the substantial quantity of silver-grade materials he had now collected, Russell felt confident that his next silver-level card advancement was within reach, whether he chose to work with Mr. Warren or approach Hazel for assistance with the crafting process.
"Now I simply need to establish a defensive position and wait for the remainder to come to me," Russell concluded after finalizing his tactical assessment.
He instructed his summoned cards to monitor the surrounding area for approaching threats while he entered a meditative state to recover his energy and maintain peak readiness for future encounters. The remaining demons were essentially scattered survivors at this point, so he felt comfortable allowing Unohana and his other cards to handle routine engagements while he conserved his strength for more significant challenges.
Over the following hours, Russell's patience was rewarded when two additional silver-level demons attempted to escape through the main gate. Unfortunately for them, they arrived during a period when Lily's Caliburn had been restored to full functionality after its twenty-four-hour recovery cycle.
Both demons were eliminated without offering any meaningful resistance to the legendary sword's devastating power. Their desperate flight ended in swift and decisive death, adding two more high-quality material specimens to Russell's growing collection.
During the subsequent two days, no demon dared to approach the metal gate, which had effectively become a recognized death zone under Russell's complete control. The psychological impact of the mass casualties and obvious tactical superiority had broken whatever remained of organized resistance or escape attempts.
Russell finally opened his eyes from his extended meditation period and rose to his feet with fluid grace. His energy reserves were completely restored, his cards were at full capability, and his strategic position was unassailable.
"In that case," he said with satisfaction at how perfectly the situation had developed, "I suppose it's time to seek out the remaining survivors myself."
After dismissing his summoned cards and allowing them to return to their portable forms, Russell transformed into his full Arrogance state and launched himself into the air above the underground complex. His destination was the main settlement area, where his enhanced senses had detected the surviving demons gathering together in what was probably their final desperate conference.
As he flew through the vast cavern system, Russell extended his mental perception to its maximum range to ensure he wouldn't miss any silver-level entities who might be attempting to hide in remote locations or escape through alternate routes that he hadn't yet discovered.
Finally, as he approached the devastated settlement area where his assault had begun, Russell's eyes brightened with predatory satisfaction. His enhanced senses confirmed what he had hoped to find.
"The survivors have actually gathered together in one convenient location," he observed with genuine pleasure at this development. "This will save me the considerable trouble of hunting them down individually across this entire underground maze."
The tactical advantage was overwhelming a concentrated target in familiar terrain, with no possibility of reinforcement or escape. It was the perfect setup for delivering the final blow to what remained of the underground demon society.
Along with a terrifying roar that echoed through the cavern system like the cry of some primordial predator, Russell's black and red form descended toward the earth with a shrill wind, ready to complete his mission and eliminate the last remnants of organized resistance.
End of Chapter 127
