Chapter 17: The Blueprint Spiral
The journey north to the Echoing Caverns was supposed to be a tense, vigilant trek through hostile territory. Instead, it turned into the most intense, hyper-focused crafting bender of my entire life.
The moment we cleared the outer traffic of Oak Haven and hit the straight, well-paved expanse of the King's Highway, I practically locked myself inside the Veil Sanctuary's workshop.
I needed materials, and since I was dead broke, I had to make my own. I stood at one of the heavy wooden workbenches and activated Imagination Manifestation. I pulled ambient earth and iron through my core, refining it with the heat of my sapphire lightning, and poured it out onto the table as a solid, dark-blue ingot of Soul-Steel.
It was exhausting work. I would push my mana pool to the absolute brink, slump against the wall until my stamina regenerated, and then do it all over again. By the afternoon of the first day, I had a small, neat pyramid of high-grade Soul-Steel bars stacked in the corner.
"Nero, you're going to burn your core out," Aria said, stepping into the workshop. She looked at the glowing pile of metal, then up at my sweat-drenched face. "What exactly is the point of hoarding raw ingots right now?"
I wiped my forehead with the back of my arm and grinned. "Because, Aria, we aren't just going to ride around in a wooden cart forever. We're going to build the Ark Angel."
I cleared off the center of the workbench and started pitching my vision. I didn't just want a carriage; I wanted a fully armored, self-sustaining mobile fortress. Something that could traverse any terrain, deploy heavy artillery, and eventually, take to the sky.
As I got deeper into the explanation, we naturally gravitated out of the workshop and into the main living area to spread out her parchment maps.
Neither of us really noticed when the carriage shifted slightly, or when the reins slipped from my abandoned spot on the driver's bench. Outside, sitting heavily on the wooden planks, Bee had calmly taken the reins in his massive metal hands. With Fenris pulling and the artillery golem steering, the two constructs formed an autopilot system that was completely absurd, but entirely functional. The road was straight, so we just let it happen.
Inside the cabin, the creative spiral had fully taken hold.
Words weren't enough to explain the complex mechanics I wanted, so I started using my magic to show her. Thanks to my massive Intelligence stat, my memory recall was flawless. Every mecha anime I had ever watched, every sci-fi game I had ever played, and every single plastic model kit runner I had meticulously snipped, sanded, and assembled over the years was perfectly indexed in my brain. I knew how internal frames worked. I knew where actuators needed to sit to prevent armor clipping.
I channeled a thin stream of mana, molding scraps of Soul-Steel and loose iron into highly detailed, miniature 3D models right on the table.
"Look at this," I said, assembling a sleek, aerodynamic hull over a set of heavy, all-terrain treads. "If we reinforce the outer chassis with localized kinetic shielding, we don't have to sacrifice speed for heavy armor. The entire superstructure can act as a mobile dock."
Aria leaned in, her eyes wide as she studied the miniature tank-like structure. "Fascinating. The sloped angles would naturally deflect physical impacts. But Nero, the sheer weight of storing a dozen heavy combat golems inside a flying vessel would throw the spatial physics completely out of alignment. How do we account for the mass? The runes required to keep that afloat would drain a master crystal in minutes."
"We don't have to worry about the full mass of the mechs," I replied smoothly. I grabbed a loose scrap of iron from the table and forcibly compressed it down with my mana until it formed a dense, marble-sized sphere. "Because of my magic, my constructs don't stay at full size when they're deactivated. You saw me do it with Fenris at the Guild parking bay—they compress down into dense, physical cores. We don't need massive cargo bays to hold fifty-foot mobile combat suits. We just need a storage rack."
I tapped the small metal sphere. "For the bigger mechs, the cores will be about the size of a boulder. They'll be incredibly heavy, but manageable. We can build a rotary, revolver-style magazine deep inside the carrier's armored gut to store them. Then, we connect that magazine directly to the front 'legs' of the vehicle."
I used my mana to quickly shape two long, forward-jutting rails on the front of the miniature model.
"We use those legs as electromagnetic linear catapults," I explained, tracing the path with my finger. "We charge the rails with my sapphire lightning and fire the heavy spheres out at supersonic speeds. Mid-flight, the kinetic energy triggers the release. The sphere 'pops' open, the armor plates expand along the internal frame, and the mech hits the ground fully formed and ready for combat."
Aria stared at the small metal orb on the table, her jaw dropping. "You bypass the physical laws of mass containment by compressing them into localized kinetic spheres? And you want to use the vehicle's structural prongs as a high-velocity electromagnetic delivery system? That... that solves the entire ballast equation!"
She immediately snatched up a quill and began frantically sketching blueprints. She drafted the rotary magazine, calculating the exact hydraulic pressure needed for the internal tracks to feed the heavy cores into the launch rails without jamming.
I didn't stop there. With the carrier's launch system theoretically solved, I started rapidly prototyping my next major project.
I molded a small avian frame out of scrap iron, carefully crafting the intricate, articulated wings of a raven. "I'm also thinking about upgrading my own combat style," I explained, manipulating the small metal bird on the table. "Getting my butt kicked by Mistress Vael's folding weapon all week gave me an idea. What if my scythe wasn't just a static piece of Soul-Steel? What if it was a sentient golem?"
I shifted my mana, and the small metal raven folded in on itself in a cascade of interlocking parts. The wings locked together, feathers overlapping to form a long, heavy polearm shaft, while the tail and beak expanded outward, clicking into place as a wicked, oversized crescent blade.
"A golem that performs a one-to-one mechanical reconfiguration into a high-tech scythe," I said, a massive grin spreading across my face. "It can act as an aerial scout, giving us eyes in the sky. And when I need it, it dives down and transforms into my primary weapon. I can even build exhaust ports into the spine of the blade to vent my sapphire lightning, using the explosive recoil to accelerate my swings and maintain the momentum Vael drilled into me."
Aria's eyes practically sparkled as she looked at the transforming model. She reached out and tapped the miniature blade. "A shifting weapon with its own autonomous core... the tactical applications are endless. But the structural stress on the joints during transformation will be massive. We just need a highly conductive, incredibly durable material to handle that kind of localized energy output without melting the internal servos."
"Which is exactly why we need this crystalline ore," I nodded.
For the next twenty-four hours, the carriage became a whirlwind of cross-world engineering. We barely slept. The landscape outside slowly transitioned from the dense, vibrant greens of the Oak Haven forests to the jagged, rocky crags of the northern territories, but we didn't even notice. We ate leftover tavern food while actively mapping out the gear ratios for the scythe's transformation and debating the precise mana-conductivity of the crystals we were about to mine.
Suddenly, the carriage gave a slight lurch, the wheels crunching against loose gravel, and rolled to a smooth, heavy stop.
The low, rumbling hum of Fenris's electrical mane outside dialed back to an idle crackle. A second later, the heavy, rhythmic thud-thud-thud of Bee's metal footsteps echoed as the massive artillery golem climbed down from the driver's bench and planted his feet in the dirt, securing the perimeter.
"We're here," Aria breathed, looking up from the sea of scattered blueprints, her fingers stained black with ink.
I cracked my neck, feeling the heavy, satisfying burn of a leveled-up mana pool. I grabbed my current, static Soul-Steel scythe—the one Vael had spent all week teaching me how to actually use—and slung it securely across my back.
"Alright, chief engineer," I said, pushing the back door of the carriage open. "Let's go get our crystal so we can actually build this stuff."
We stepped out into the cool, damp air. Towering ahead of us, cut into the side of a massive, jagged rock formation, was the gaping, pitch-black maw of the Echoing Caverns. The ambient mana in the air here felt different—sharp, static, and heavy enough to make the hair on my arms stand up.
"Bee, Fenris, on me," I commanded.
The silver wolf trotted to my right side, his blue optics piercing the gloom, while Bee took up the rear, his triple-barrel machine gun arm spinning up with a menacing, metallic whir.
