As soon as it touched his tongue, it dissolved. The mana surged inward, spreading through his chest and down his limbs, flooding his core like a sudden sunrise.

His breath hitched as he circulated it through his Mana Veins, guiding the flow as he had practiced. The effect was both violent and miraculous at once.Warmth spread into torn muscle, bruised tissue, and strained channels, knitting damage with visible speed. The ache in his ribs dulled.

The tear in his leg sealed with a faint itching sensation. His depleted mana pool filled rapidly; pressure built within him, not painfully but firmly, like a container being expanded from within.

When he exhaled again, the cavern felt different, or rather, he did.

"…Absurd," Sage whispered under his breath.

He stood up, flexed his fingers, and turned toward what remained of the boss. The corpse had partially dissolved in the mana river, but much still remained.

Sage retrieved a knife from his satchel and began working with methodical precision to extract the monster core embedded deep within its chest cavity.

He pried away hardened scales that still radiated faint heat and separated bones dense enough to ring when struck against stone.

He worked without haste, collecting everything of value, resources that would one day become catalysts or profit. By the time he finished nearly two hours had passed.

Straightening up and rolling his shoulders back, he looked at the pile beside him.

"Store it," he said.

[This system is not designed to function as a long-term physical inventory.]

Sage glanced sideways. "You're really hung up on that."

[Resource overflow increases systemic inefficiency.]

"Come on," Sage replied lightly. "What kind of system are you if you can't hold a few monster parts?"

[Define 'few.']

He gestured at the pile.

[…]

After a long pause, the materials vanished into light.

[Temporary storage parameters adjusted.]

Sage grinned faintly. His gaze drifted back toward the now-silent cavern as Gregor's earlier words surfaced clearly in his mind. Dungeon monsters regenerated; they were not part of a natural population or beasts reproducing biologically, they were outputs.

When killed, the dungeon simply produced replacements drawn from its internal system and shaped by its rules. Clearing a dungeon didn't empty it; it only reset it. Only destroying the core truly ended the cycle, and only an idiot would destroy a resource that could grow endlessly.

Dungeons weren't disasters; they were treasures.

He turned away, the ascent back feeling slower, quieter, almost meditative. Without the weight of active hostility, the dungeon transformed into a slumberingmachine, its corridors steady, torchlight unwavering, and the air no longer pressing against him. He ascended floor by floor until he finally stood before the portal once more.

Stepping through, he froze in place as shock and confusion washed over him. His eyes widened at the sight before him.

The world outside had undergone a dramatic transformation. Where there had once been weeds, leaning stones, tall grass, and scattered trees now lay massive stone structures, deliberate and shaped with purpose.

A wide platform stretched beneath his feet, smooth and dark, etched with faintly glowing lines that pulsed red and blue in a slow rhythm.

Two towering pillars flanked the portal, intricately carved with runes and geometric motifs that exuded a sense of restrained power. Around the portal itself shimmered an expansive circular mana formation, layers of glowing script rotating like interlocking seals.

Beyond this platform stood evenly spaced stone columns forming a perimeter; from one end extended a newly formed stone road that cut straight into the night as if the land itself had embraced an architectural correction.

Sage's mouth fell open slightly. "What… what is this?" he breathed in disbelief. "System, explain."

[Dungeon Claim Protocol completed.]

[Protective Formation deployed: Sovereign Threshold Array.]

[Unauthorized entry preventionactive.]

Sage frowned. "Can you put that in simpler terms?"

[The formation prevents any entity from entering the dungeon without a registered Dungeon Pass.]

His interest piqued at this revelation. "A what?"

[Dungeon Pass: access authorization construct issued through the Guild. Functions as a spatial key for safe traversal through the Sovereign Threshold Array.]

"So without it?" Sage asked slowly.

[Contact with the formation will result in repulsion, restraint, or lethal counter-reaction depending on threat assessment.]

Sage stared at the shimmering seals before him and then smiled.

"So it's like a passport," he murmured to himself. "No pass means no entry."

A soft sigh of relief escaped him as thoughts raced ahead, not toward defense or fear but toward systems of control and pricing strategies.

"…Another way to milk them," he muttered dreamily.

The system continued its explanation about how this formation interfaced directly with Guild authority and how Dungeon Passes were regulated or revoked. Sage barely blinked as he listened; his gaze drifted across the platform until realization struck him like a heavy weight.

The entire setup, the platform's design and geometry, resembled the Adventurer Guild's symbol closely.

This wasn't just protection; it was branding, ownership etched into reality itself. Had this dungeon been claimed without such measures in place, anyone could have walked right in unimpeded.

He would have needed guards and walls, resources he currently lacked compared to powerful nobles, but now that problem was effectively solved for him.

With this in place, no one could enter without his permission.

A broad grin spread across his face. "This…" he murmured, "this has saved me years of headaches."

Years spent defending himself, years tangled in conflict, and years struggling with logistics that seemed impossible to solve. Now, all he had to focus on was survival.

Once these dungeons became public knowledge, the nobles wouldn't overlook the fact that someone else had taken the initiative. They would be coming for him, and that was what truly concerned him.

Sage cast one last glance at the glowing platform and the pulsating portal now nestled within an area that felt less like untamed wilderness and more like a structured facility before turning away.

The second set of coordinates stillburned vividly in his mind. The night had more in store for him yet.
