# Chapter 3 — Echoes in the Ruins
The timer ticked down in the corner of my vision.
**35:42 Remaining**
Not much time. Not nearly enough.
The Scout Construct hovered beside the pile of materials it had gathered, its single blue eye flickering like a candle in the wind. It chirped once, almost proudly, before dissolving back into particles and returning to the Node’s internal storage.
I knelt beside the materials, sorting through them. Metallic debris, residue, core fragments… and the Null-Pattern Shard. The strange one. The one that shouldn’t exist.
I held it up to the light.
The shard didn’t reflect anything. It absorbed it—drinking in the glow of the dome, swallowing the faint blue veins of the street outside. A tiny ripple pulsed across its surface, like a heartbeat.
“What are you?” I whispered.
The System pulsed.
**[Null-Pattern Shard: Origin Unknown]**
**Potential: High**
**Warning: Unstable. Handle with caution.**
Unstable. Great.
I set it aside and opened the Fabrication menu again. The Nullweave Lattice blueprint hovered in front of me, incomplete and pulsing faintly.
**[Nullweave Lattice Requirements:]**
— 1× Null-Pattern Shard
— 3× Metallic Debris
— 2× System Residue
— Additional Component: Unknown
Unknown. Again.
The System wasn’t giving me answers, but it was giving me direction. And direction was enough.
A distant rumble echoed through the street. Not the massive shadow from earlier—this was sharper, quicker, like something skittering across metal.
I stood and approached the barrier, peering out.
The city was still empty. Still silent. Still wrong.
But something had changed.
The glyphs in the sky pulsed faster now, their rhythm tightening like a drumbeat. The obsidian streets glowed brighter, the veins of light pulsing in sync with the timer.
The world was reacting to the countdown.
The First Hour wasn’t just a challenge.
It was a transformation.
The System chimed softly.
**[Tip: Environmental shifts indicate incoming event triggers.]**
**[Tip: Prepare constructs before event activation.]**
“Prepare constructs,” I muttered. “With what cores?”
The System didn’t answer.
I paced the dome again, thinking. I needed more materials. More cores. More… everything. But leaving the dome now, with that shadow creature roaming the streets?
Not happening.
Unless—
I opened the Construct menu.
**[Construct Deployment Options:]**
— Scout Construct
— Primitive Construct (Explosive)
— Empty Slot
— Empty Slot
Two empty slots. Two potential minions I couldn’t build yet.
But the Scout Construct could gather more materials. And if I sent it farther…
“System,” I said quietly, “can the Scout avoid the large hostile?”
**[Affirmative. Threat Avoidance Protocol: Active.]**
“And can it search a wider radius?”
**[Affirmative. Range increased to 200 meters.]**
That was enough.
I crafted a second Scout Construct—burning through the last of my debris—and sent both drones out into the ruins.
They zipped through the barrier, vanishing into the streets like sparks swallowed by darkness.
The dome hummed again.
**[Scout Constructs Deployed]**
**Status: Searching…**
**Threat Avoidance: Active**
**Return Time: Unknown**
I sat down, back against the Node, and watched the timer.
**33:10 Remaining**
The silence pressed in again. Heavy. Suffocating.
I closed my eyes for a moment, trying to steady my breathing.
Then—
A faint sound.
Not outside.
Inside.
A soft, rhythmic tapping beneath the floor.
Tap.
Tap.
Tap.
My eyes snapped open.
“What now…”
The tapping grew louder, more insistent, like something knocking from beneath the dome’s foundation.
The tale has been taken without authorization; if you see it on Amazon, report the incident.
The System pulsed sharply.
**[Warning: Subsurface anomaly detected.]**
**[Origin: Unknown]**
**[Distance: 1.4 meters below Foundation Node]**
Below me.
Something was under the dome.
I scrambled to my feet as the floor vibrated—just slightly, but enough to feel through my boots. The Node’s hum shifted, rising in pitch as if bracing itself.
The tapping stopped.
Silence.
Then—
A crack appeared in the floor.
Thin. Hairline. Glowing faintly with the same blue light as the streets outside.
The System flashed red.
**[Critical Warning: Foundation Integrity Compromised]**
**[Unknown entity attempting breach]**
My pulse spiked.
“Not now,” I whispered. “Not now.”
The crack widened.
A second one branched off.
The floor trembled.
Something was pushing up from below.
The timer ticked down again.
**32:41 Remaining**
The First Hour wasn’t waiting.
It was coming for me.
The cracks spread faster than I could track them—thin glowing lines spiderwebbing across the floor beneath the Foundation Node. The dome flickered, its hum rising into a strained whine.
The System pulsed violently.
**[Foundation Integrity: 92%… 89%… 84%]**
**[Unknown entity attempting forced emergence]**
Forced emergence.
Something wasn’t just trying to break in.
It was trying to *enter* the dome.
I backed away from the spreading fractures, heart pounding. The Node’s glow dimmed, then flared again, as if fighting off whatever clawed at its underside.
A low, muffled screech echoed from beneath the floor.
Not mechanical.
Not animal.
Something in between.
The cracks widened.
A chunk of the floor buckled upward.
“No, no, no—”
The System flashed red.
**[Immediate Threat: Subsurface Aberrant — Tier 0+]**
**[Behavior: Burrowing / Seeking Energy Source]**
**[Recommendation: Prepare for breach]**
Prepare? With what?
I had no weapons.
No combat skills.
No constructs ready to fight.
The Node shuddered again, the dome flickering dangerously.
**[Integrity: 78%]**
Another screech tore through the chamber—louder this time, vibrating through my bones. The floor bulged upward, stone cracking like brittle glass.
Then—
A claw punched through.
Long. Metallic. Jointed wrong. Its surface shimmered with the same glyph?patterns that covered the sky, pulsing in jagged rhythms.
The claw scraped against the underside of the dome, sending sparks of blue light scattering across the floor.
I stumbled back, nearly tripping over the pile of materials.
The System chimed sharply.
**[New Option Available: Emergency Construct Deployment]**
**[Cost: 1 Core Fragment + 1 Metallic Debris]**
**[Result: Improvised Guardian Construct (Unstable)]**
Unstable or not, it was all I had.
“Do it!”
The materials dissolved into light, swirling into a rough, skeletal shape. A small construct slammed into existence—jagged limbs, a flickering eye, its frame barely holding together.
It screeched a metallic cry and hurled itself at the breach.
The claw tore upward again, widening the hole. A second limb emerged—then a third. The creature beneath the dome was forcing its way through, its body scraping against the Node’s defenses.
The Guardian Construct leapt, slashing at the exposed limb.
Sparks flew.
The creature shrieked—an awful, grinding sound—and jerked back. The floor cracked further, the breach widening.
The System pulsed.
**[Enemy Health: 87%]**
**[Guardian Construct Stability: 42%]**
Not enough.
The creature surged upward again, slamming its limbs against the dome. The barrier flickered violently, its glow sputtering.
**[Integrity: 63%]**
The Guardian Construct attacked again, claws raking across the creature’s limb. The aberrant screeched and slammed the construct into the floor, shattering part of its frame.
**[Stability: 19%]**
“Come on,” I whispered. “Hold together—just a little longer.”
The creature forced its head through the breach—a mask?like face split down the center, porcelain cracked and glowing with blue veins. Mandibles twitched beneath the broken shell.
It looked like the insectoid creature I’d fought earlier.
But bigger.
Stronger.
Evolving.
The System flashed.
**[Aberrant Variant Detected: Burrower Drone]**
**[Tier: 0+]**
**[Behavior: Assimilate / Consume / Expand]**
Expand?
The creature lunged upward, slamming its head against the dome. The barrier rippled, nearly collapsing.
**[Integrity: 51%]**
The Guardian Construct leapt again—its final attack—driving its claws into the Burrower’s exposed joint.
A burst of blue light erupted.
The construct detonated.
The explosion blasted the creature backward, forcing it down into the hole it had torn open. The floor shook violently, dust raining from the dome’s interior.
The System chimed.
**[Enemy Health: 32%]**
**[Guardian Construct: Destroyed]**
The creature screeched, thrashing beneath the floor. The cracks widened again—then stopped.
Silence.
A long, tense silence.
Then the System pulsed softly.
**[Threat Retreating]**
**[Burrower Drone returning to subsurface tunnels]**
**[Foundation Integrity Stabilizing]**
The cracks stopped spreading.
The dome brightened.
The hum steadied.
I collapsed to my knees, breath shaking.
The timer ticked down.
**29:58 Remaining**
Half an hour left.
And that was just one creature.
The System pulsed again—calmer this time.
**[New Objective: Strengthen the Foundation Node before the next breach attempt]**
**[Hint: Null-Pattern Shard may interact with Node architecture]**
I stared at the glowing shard lying beside me.
The one that absorbed light.
The one that pulsed like a heartbeat.
The one that shouldn’t exist.
The First Hour wasn’t just about surviving.
It was about adapting.
And if the world was evolving…
I had to evolve faster.
I picked up the shard.
The Node hummed in response.
The next phase had already begun.
