Obsessive Study of Electric Fire Dispels Confusion, A Slap to the Disciple's Shoulder Asks About Strengths and Weaknesses

Rong Jian's gaze locked firmly onto the small generator. His fingers unconsciously brushed the carbonized bamboo filament at its top, and a rough texture met his fingertips.

His brows drew together slightly, his eyes full of doubt and uncertainty.

This pitch-black bamboo filament—if you said it could light up when burned, that he could understand. But connect it with a few copper wires, and you expected it to light up?

Could sparks have been produced by friction?

Before he could think further, Xiangli Qin had already gripped the generator's crank and begun turning it at a steady pace.

As the crank turned with a "creak, creak," the copper-wire coil swept rapidly past the magnet, and an electric current so faint it was almost imperceptible quietly began flowing through the copper wire.

The current traveled along the wire and ultimately reached the carbonized bamboo filament.

The next second, the carbonized bamboo filament gave a slight tremble, first blooming with a dim yellow glimmer.

Then, after flickering several times, a distinct ray of light suddenly flared to life, casting a gentle halo through the dim little room.

"Huh?"

Rong Jian's gaze froze. He unconsciously leaned half a step forward, even softening his breathing.

He stared fixedly at that ray of light.

There was no flame, no smoke. It simply shone there quietly, softer than an oil lamp, yet brighter than candlelight!

With his cultivation, he could vaguely sense an extremely faint energy lingering around the generator.

Yet no matter how intently he probed or racked his brains, he could not deduce where this energy came from, nor how it made the bamboo filament glow.

A long-lost thirst for knowledge shot up like a flame, burning his heart hot.

He was the Mohist Grandmaster, a man steeped in Mechanism Arts his entire life.
