[Ding!]

============

[Quest: The first dungeon.]

Objective: Finish the first dungeon task and obtain the basic understanding of the dungeon structure and elements.

Rewards: Architect EXP (+30), Coins (+1000), Creation Units (+20), Essence Points (+30)

============

That was the quest panel I saw before my focus shifted on the dungeon structure itself, on not just the physical aspect of the dungeon but also the creation aspects.

The dungeon wasn't just a hollow shell anymore.

From this vantage point, floating like a detached ghost, I saw it all spread beneath me— no, through me.

The walls weren't stone, they were structures. Mana didn't just glow, it pulsed like fiber optic cables threading through a server rack.

And the deeper I gazed, the more the illusion of dungeon-as-cave fractured into dungeon-as-system.

Blue veins of energy spiderwebbed through corridors, converging into thicker channels, then dispersing again.

Some hummed steadily, a constant low bass that reverberated through my spectral form. Others slowly flickered irregularly, like faulty neon lights, threatening to wink out any second.

[ "The dungeon framework has acknowledged your entry." ]

The sudden change in perspective was perhaps the result of that acknowledgment.

The system's voice drifted through my head like a steady metronome. Not harsh, no it wasn't. Not robotic like the Alex or Sirian. Just steady enough to anchor me while the entire world tried to overwhelm me.

[ "As a guest Architect, you are granted elevated perception and conditional privileges. You may not alter this dungeon without explicit authorization from its core, but you are free to observe, analyze, and interact with designated subsystems." ]

I tilted my head, or thought I did— orientation didn't exactly work when you didn't have bones. "Conditional privileges, huh? Sounds like a corporate VPN with half the site tabs blocked."

[ "Comparable," ] the voice agreed without hesitation.

I couldn't help it as I grinned at that agreement. Whoever— or whatever— was running this pink screen had already learned how to speak fluent Aria.

I was so high up right now that the rookies in the frozen chamber looked almost laughably small. All nerves and sweat and clenched fists. From this height, they weren't adventurers in training, they were data packets about to be routed.

'And me? I am the sysadmin with god-tier permissions.'

The thought should've terrified me. Instead, it felt… right.

[ "Observe closely." ]

The system-sister's command pulled my attention forward. The frozen entry chamber blurred, and suddenly I was sliding, drifting, phasing through the dungeon itself.

Walls parted around me like curtains. I crossed what felt like hundreds of meters in seconds, soaring deeper than the rookies would ever be allowed.

The dungeon unfolded in layers. Corridors stacked on corridors, stairwells spiraled endlessly, caverns yawned like hollow lungs.

Monsters, paused mid-step, hung suspended in the gloom. A wolf mid-snarl, teeth bared but frozen. A slime caught mid-drip, droplets dangling in air like glass beads.

I passed through countless sections of the dungeon and soon, I saw it from a perspective which I cannot even call godly.

The network. It was right there… the foundational structure building this entire dungeon.

Thick clusters of mana channels braided together, glowing brighter than the others, feeding power into vast lattices that underpinned the dungeon's bones.

From far away, it looked almost beautiful— like a cosmic neural network, each pulse a thought firing across a synapse.

'The dungeons are alive.'

When I first thought about them as monsters in the shape of architectures, I wasn't wrong. Instead, it was precisely what this was… a living entity not much different from humans or creatures.

But when I looked closer?

Closer, I noticed the errors.

One cluster thrummed unevenly, strands of energy knotted over themselves, tangled like frayed wires.

The blue pulses skipped, staggered, collided, becoming unrhythmic, harming the complete harmony. Each misfire sent faint tremors echoing through the surrounding stone, which resulted into a physical error on such a micro scale that even I would never notice it as a human.

I frowned at the mere sight of this anomaly. "That doesn't look healthy."

[ "Correct." ]

The sys-voice didn't hesitate.

[ "This channel is unstable. A flaw in the structural weave. If left unresolved, it will manifest as corrupted monster generation, resource decay, or boundary breach." ]

"Translation: big mess, very bad, please fix ASAP."

[ "…Accurate." ]

My grin was sharp this time, even though I shouldn't even have been smiling at this moment.

This was the first thing that made sense to me since I'd landed in this insane world. These weren't swords that demand function. Not magic that's completely unfamiliar. Not prayers to invisible deities that I don't even believe in.

This—this I understood. Broken systems, tangled networks, the need to debug before the whole thing went to hell.

I didn't have the laptop screen or a keyboard to type the code, but in a world where magic was run through mana and imagination? I was as good as the traditional artists from my previous world.

[ "Since the dungeon has recognized your presence, it has prepared a task for you." ]

-Oooooooong!

A faint chime rang out. My vision flickered, then solidified into a single clean status window hovering before me— not blue of the world, not pink of my personal assistance system, but a green one.

============

[Guest Task (1) Assigned]

Task: Untangle the Mana Channel.

Details: Correct the instability within the designated cluster.

Attempts Remaining: 3

Reward: CU (+50), EP (+30), Coins (+10,000).

Failure: Guest Privilege lockout for (30 days).

============

My spectral stomach dropped the moment those details were processed in my ghost-brain. "Oh, hell no! A three-strike policy? I didn't sign up for baseball!"

But even as I grumbled, my heart was racing.

This wasn't like answering exam questions. This wasn't like bluffing through skill demonstrations. This was different. This was… mine.

[ "The Assistance System is here to assist the owner." ]

Smiling at the sweet words of the system, I reached out toward the tangled cluster, my ghostly hand trembling as threads of mana pulsed and snarled before me.

"Alright then," I whispered, eyes narrowing. "Show me what you've got."

And the pink glow deepened, folding the world tighter around me until there was nothing but me, the knot, and the first real challenge of a Dungeon Architect remaining.
