**Doomsday Rebirth 480**
**Chapter 480: The Enemy in the Shadows**
Beneath the heavy weight of burlap sacks, a small inscription caught Caroline’s eye: “Can be used to fertilize Farm One or Farm Two to enhance crop yield.” Right beside it, a crude vomiting emoji seemed to mock her predicament. The message was unmistakable—it was taunting her, reminding her of the grim reality she faced. “Did you forget you still have Farm One? You can dump the bodies there! The fertilizer’s ready. Just stop torturing the waste processor and bury them already. Please!”
As she stared at the countless bags brimming with corpses, a wave of unease washed over her. What could possibly sprout from Farm One if she truly buried them there? The thought churned in her mind, but time was a luxury she couldn’t afford. With a determined resolve, she diverted two-thirds of the energy pulsing from the bodies to fortify the shelter’s walls.
The remaining energy was allocated to recharge the mobile base, a necessity for their survival. For the wall upgrade, Caroline opted to reinforce and elevate them further. The walls now loomed at an impressive 13 feet, their density doubled, a formidable barrier against any threat. This upgrade alone consumed a hefty portion of the energy, but it was a risk worth taking.
With the walls reinforced, she moved on to activate the “Enemy Alert” function. Unfortunately, with the scant energy she had left, she could only engage the most rudimentary level—an alert that would detect any hostile presence within a mere 33 feet. It wasn’t much, but it was a start; she could always expand the range later.
Just as she completed the upgrade, a steady vibration pulsed beneath her feet, a clear indication that the alert system had been triggered—an enemy was lurking nearby, no more than 33 feet away.
Caroline’s heart raced as her gaze snapped to the main gate of the base, her senses sharpened to their utmost. The world outside was eerily silent, yet her instincts screamed that danger was lurking just beyond the door.
Then, a faint rustling echoed through the stillness.
Someone was attempting to breach the mobile base’s gate.
The subtle tremor beneath her feet quickly roused everyone from their rooms, their expressions shifting from confusion to alarm.
“Caroline, is that an earthquake?” Denton asked, his voice tinged with panic.
“Shh,” Caroline urged, placing a finger to her lips, her eyes never leaving the door.
As the others gathered, the alert system automatically quieted, sensing their collective tension. They fell into a hushed silence, awaiting the next sound.
The faint scraping at the lock intensified, unmistakable evidence that someone was indeed trying to force their way in.
Caroline exchanged a quick glance with Tyler, who nodded in understanding. She gestured to Denton, and the two of them positioned themselves strategically on either side of the doorway.
Tyler stepped forward to the control panel, his expression resolute as he prepared to respond to the threat. The mobile base’s lock was designed to be impenetrable from the outside; only a unique key or an internal release button could unlock it.
With a swift motion, Tyler pressed the small button. A sharp click echoed in the tense air as the lock disengaged.
His skin had already transformed into a metallic armor, blades extending from his hands, poised for action.
