GameDev Reincarnated into His Own Creation

Vol 2 - Chapter 25: Flush

Celia's brow furrowed before understanding dawned. "The lightning will spread through the water..."

"Exactly," Vel nodded. "Water and salt make the perfect conductive elements. The current will stun all the slimes simultaneously without damaging the non-conductive materials like glass and silk."

Vel turned his attention to the logistics of their improvised plan.

"We need to plug that drain first," he pointed to the corner where water would escape through. Without it sealed, they'd never build up enough water for the plan to work.

The merchant followed Vel's gaze and nodded in understanding. "I have this."

Belwin cautiously descended the last few steps, skirting around a particularly aggressive blue slime that lunged toward his boot. He reached the corner drain and twisted an iron handle beside it, shutting off the drainage system with a metallic screech. Once the drain was sealed, he quickly backed away, taking the stairs two at a time.

"Alright, everyone stand back," Vel instructed, positioning himself at a safe distance from the basement floor.

He focused, drawing mana into his core as he prepared to cast. The sigils for water generation formed in his mind, and he raised his hands toward the basement opening.

"Fluvenis Aquar Vastare!"

Water materialized from his outstretched hands, cascading down into the basement in a powerful stream. The torrent was far stronger than a simple conjuration—this was continuous generation, designed to fill rather than merely exist.

Minutes passed as Vel maintained the spell, sweat beading on his forehead as his mana reserves steadily depleted.

This much mana already costs more than five silvers, Vel thought bitterly. The payment for this job was looking increasingly inadequate as he poured literal energy into solving the merchant's problem.

The slimes began to float as the water level rose, their gelatinous bodies bobbing harmlessly on the surface. The precious merchandise remained mostly submerged, protected from direct contact with the creatures. When the water reached halfway up the basement walls, Vel finally cut off the spell, stepping back and wiping his brow.

"Celia, your turn," he said, nodding toward the flooded basement.

Celia drew her rapier with a flourish, its slender blade gleaming in the dim light. She approached the edge of the basement floor, now transformed into a murky pool containing dozens of floating slimes.

The creatures bobbed and rolled on the surface, producing soft gurgling sounds—almost like mischievous laughter—that made Vel grimace. How did they even make noise without vocal cords? The slimes seemed to be enjoying their chaotic mess. Without hesitation, she extended her arm and plunged the tip of her rapier into the water.

"Trinity Volt!" Celia called out, her voice steady as she executed her sword art with smooth confidence.

Instead of striking the slimes directly, she aimed at the water's surface near her feet. The rapier's tip glowed with crackling energy before discharging into the liquid. Blue-white electricity arced from the point of contact, dancing across the water's surface in jagged patterns.

The current spread instantly, linking every conductive point in the basement. Vel watched in fascination as electricity found the path of least resistance through the water and the salt, creating a deadly network that ensnared every slime.

The gelatinous creatures jolted violently. Their bodies convulsed outward, stretching as if being pulled from a hundred different directions at once. Some expanded to twice their original size, their translucent forms distorting grotesquely as electricity coursed through them.
