Reincarnation of Nikola Tesla in another world-Chapter 13: Turbineless motor

Four days later, the ringing of Brom's hammer pulls me out of the inn before sunrise. The forge is alive, metal clashing against metal, sparks flickering in the dim morning light.

Aldric sidles up beside me, rubbing his eyes.

"Kim, how will you make it work?" he asks, still groggy. "I mean, maybe someone's already tried this and failed. That's why machines like this don't exist, right?"

I let out a quiet chuckle. "You see, I've been reading through those books I bought. Mana crystals alone aren't enough. We need to actually move the sheets."

Aldric frowns. "And how do we do that? Magic?"

"Not exactly."

I grab a crumpled piece of paper and shove it in his hands. The drawing is rough, lines rushed.

"Runes," I say. "Ancient symbols that control mana flow. We inscribe them into the casing, and they handle the energy transfer. Think of it like... guiding water through a pipe instead of letting it flood everywhere."

Aldric squints at the scribbled symbols. "Runes? So... a fancy word for making things spin?"

I sigh. "Something like that."

I lower my voice. "But keep this between us. Brom doesn't need to know yet."

Aldric nods, still confused, but he doesn't argue. Good.

The forge door swings open, and Brom steps out, a wide grin plastered on his face. A wooden crate rests in his arms.

"Here they are," he says, voice filled with pride. "Twenty perfect metal sheets."

I take one and run my fingers along the edge. Smooth. Precise. Uniform Exactly what I asked for.

Aldric grabs one and nearly drops it in excitement "This is insane!" His eyes dart between me and Brom. "It's like... like holding history in my hands!"

Brom puffs out his chest a little. "I told you I could do it." But then, after a pause, his fingers tighten around the crate. His voice drops slightly. "Kim... if this works... this will be the first thing I've ever made that truly _matters_."

I look at him. He's serious. This isn't just a job to him anymore.

I give him a nod. "Then let's make it count."

We clear out a corner of the forge, laying the motor pieces down. Simple design but that's the beauty of it.

The metal sheets go inside a sealed casing. A shaft passes through the middle. Before fixing it shut, I carve the runes inside the cover—quick, controlled strokes. No mistakes.

With a twist of the bolts, the motor is sealed.

I take a breath and slot the mana crystal into place.

At first, the sheets barely move, turning sluggishly.

Then, a shift. A hum vibrates through the metal. The movement picks up speed. The plates spin faster, smoother, the rotation stabilizing into a steady rhythm.

Aldric claps me on the back, hard "Kim, it's—it's ...spinning! It actually works!" His voice is filled with awe, as if he's watching something impossible come to life.

Brom, who had been silent until now, suddenly laughs—loud, deep, and filled with something raw. He grips the edge of the table, shaking his head. "I never thought I'd see something like this. It's real. It's actually real."

I don't smile, "Not yet," I mutter, watching the rotation carefully. "It's just spinning. The real test is with water."

I turn to Brom. "I need iron pipes. Inner diameter must match the outlet exactly."

Brom snaps out of his trance and gives me a sharp nod. "You got it, boss. I'll have them ready soon."

His excitement is real. He sees it now, this isn't just some theory. This is real work in progress

I run my fingers along the warm metal casing. This is just the beginning.

Later that day, we set up behind the inn. An old well. A perfect test site

We lower the motor's output into the water. The rope goes taut.

At first, nothing happens.

Aldric shifts beside me, watching anxiously. "What's wrong? Did we mess up?"

I don't answer. I wait.

A small trickle of water bubbles up.

Then, pressure builds.

With a sudden burst, water shoots out, spraying upward like a fountain.

Aldric stumbles back, laughing like a madman. "This—this isn't a spell?! This is your machine?!" He points at the motor, at the water, then at me. "Kim, this is... this is powerful!"

I shake the water from my sleeve, smirking. "That's because it's not a spell."

This works. It actually works.

And that means I have a choice.

Use this to pin a rich noble, make him a scapegoat, and gain wealth fast.Or mass-produce it, create a monopoly, and control the entire market.

But now, I hesitate.

Power corrupts. I've seen it before. I've lived it before.

Aldric catches his breath, eyes burning with excitement. "What now?"

I smirk and turn to him.

"Now?" I say, tilting my head. "We find a filthy rich noble. And we sell him a dream."
