Constant Variable (Senku x Reader)

9: Let There Be the Light of Science

"There's no such thing," Senku replied absentmindedly as his mind worked to think of a solution.

"Of course," The mentalist let out a wry sigh.

A few seconds passed before Senku raised his head and said, "Magnets. I can make a generator if I have magnets."

"We have some of the iron sand that we got." Suika chimed in as she walked over to the green-haired male and held up the magnetic rock used to collect iron sands from the river.

"The natural stuff isn't anywhere near strong enough." Senku glanced down at the young girl with a small frown and took the rock from her. "We're going to catch the lightning with an iron rod and make a high-power magnet with the power of science."

"Of course!" You exclaimed as realization dawned upon you. "I remember now. Soil, rocks, and any metal materials become magnetized when struck by lightning. Right, Senku?"

The corners of his lips lifted into a smirk as the green-haired scientist nodded his head, saying, "Good job, you got that right. As expected of my assistant."

You preened at the teen's praise; your cheeks dusted a light pink.

"I was going to put up a stupid number of lightning rods, but we can't pass up this opportunity." Senku glanced at the rock in his hands, unsure of whether his new plan would work or not but that isn't going to stop him from trying either way. "We're going to set up immediately."

Just then, lightning flashed, and he turned his head towards the sky, smirking. "We're moving lightning fast."

"Literally!" You added, giggling at your pun.

With that, everyone got to work without another moment to waste for it was a race against the clock to get everything set up before the storm passed.

"Melt the copper."

Grabbing a stone ax, Chrome made a hole at the bottom of the furnace where the melted copper was removed by Senku. While that was happening, the scientist turned to the group and said in an urgent voice. "Kohaku's shield is coated with lacquer. It's somewhere in the village!"

Suika swung into action and within a few seconds, she returned from the village with a small jar in her hand. "I bought the lacquer!"

"Lacquer is a crazy good insulator." Senku explained and turned to you, saying, "(Name), I need you to coat the iron rod with it."

You nodded your head and did as told, making sure that said object was coated evenly in lacquer.

"What are you doing?" Gen muttered to himself in confusion, his eyes trained on you as you continued to coat the iron rod in lacquer.

"Wh-What are you doing with the bridge planks?" A startled Ginro asked as Senku removed the first plank of the main bridge.

Using one of her daggers, Kohaku started to carve a channel into the same wooden plank. "I carved a channel in the plank."

"Pour the copper into the channel," Senku muttered, being careful while doing just that. "Wrap the solidified copper around the iron."

You handed the iron rod covered in lacquer over to the male who was gritting his teeth as he struggled to tighten the copper around said bar.

A shocked gasp escaped Kohaku's lips when she noticed three figures making their way towards the group.

"Shoot, it's Magma!" Chrome cursed at the sight of the tall, muscular blonde.

"He's not one to listen to reason," Kohaku added and unsheathed her daggers for the oncoming fight. "We're going to have to fight them!"

"We're screwed if we go to war against the village right now," Senku growled in frustration. "Damn it, what can we do?"
