From her vantage point, Chloe's sharp eyes caught a peculiar moment amidst the flurry of activity. One of the scientists carefully poured a glowing blue liquid into a compartment in the robots' chests. The fluid swirled, its luminescent hue seeming far too vibrant for a mere power source.
"Interesting stuff," Chloe remarked, her tone laced with curiosity. "What exactly is that?"
One of the doctors stiffened but quickly composed himself, offering a rehearsed smile. "It's a new prototype battery we've developed. Far more efficient than the standard cells. State-of-the-art technology."
Chloe arched an eyebrow, crossing her arms. "Is that so? Because it looks more like you're implanting something than powering them up."
The scientist hesitated for a fraction too long, his answer forced. "It's just a unique chemical solution, perfectly safe and designed to optimize energy output."
