**Chapter 675: Level 6 Zombie**
The atmosphere was thick with tension, an urgent pulse that quickened the heartbeat of every soul present. No one dared to let their guard down, not even for a moment. Arrance and Clara, normally so focused on their own tasks, were now swept up in the collective effort, their brows furrowed with determination.
As time dragged on, thirty minutes slipped away like grains of sand through an hourglass.
Just as Theresa had foreseen, the steel mesh that had once offered a semblance of security within the tunnel lay in ruins. The relentless tide of zombies had breached the barriers, their grotesque figures now pressing against the steel plates that blocked their path.
With a single hand, Theresa gripped the thick steel plate, her knuckles turning white from the strain. Behind her, a chaotic mass of zombies surged forward, their moans and growls echoing through the tunnel like a nightmarish symphony.
“Roar!”
Time felt like molasses, each second stretching into eternity.
At the mouth of the tunnel, the air was thick with sweat and exertion. The group worked feverishly, muscles straining as they flung buckets of dirt aside, their efforts a frantic dance of survival. The two individuals at the front dug with relentless vigor, while those behind them hurriedly cleared the debris, moving in a synchronized rhythm. The slightest hesitation from anyone at the forefront would lead to them being jostled aside, a reminder of the stakes at hand.
Their energy reserves were nearly depleted, yet adrenaline fueled their resolve, driving them to dig faster and harder than ever before.
Theresa’s grip on the steel plate was unyielding. She estimated that at least a thousand zombies were crammed within the tunnel’s confines. The thought of anyone else being trapped inside sent a shiver down her spine—crushed or suffocated, there was no mercy in such a fate.
But the horde behind her showed no signs of relenting. Instead, they pressed forward with a terrifying desperation, as if sensing the fleeting nature of their existence.
If one were to gaze down from above, the scene would resemble a frenzied colony of ants, each creature fixated on the singular goal of returning to their nest, a swarm of chaos cascading into the tunnel.
Inside, the frontmost zombies had already become a grotesque amalgamation of bodies, their forms mashed together in a macabre display. The steel mesh embedded in the tunnel walls creaked, cracking under the immense pressure, oozing a dark, viscous fluid as the zombies were mercilessly crushed. They continued to push forward, their decaying bodies squeezing out the last remnants of life.
A dark pool of blood began to collect at Theresa’s feet, a grim testament to the carnage unfolding behind her.
With both hands now pressed against the steel plate, she braced herself.
Suddenly, an overwhelming force surged from within the tunnel, a wave of energy that sent a jolt through her body.
“Roar!”
“Roar!”
If it had been merely a swarm of Level 4 or 5 zombies, she wouldn’t have felt the same urgency. She had faced them before, understood their limitations. But this was different—this was a new breed, a formidable foe, and she wasn’t about to underestimate its capabilities. If she had the chance, she would retreat to a safer position, assess its strength, and then plan her approach.
Caution was her nature.
In previous encounters, such as with the three Ark camps, she could have launched an immediate attack, but she had always chosen the path of prudence, carefully evaluating her opponents before engaging. The only time she had acted recklessly was against the Starborn Order, and that had been a matter of survival.
Now, however, she found herself face-to-face with a Level 6 strength-type zombie, lurking just beyond the steel barrier.
Thud!
The plate shuddered once more.
The Level 6 zombie slammed into it with all its might, each collision sending shockwaves through Theresa’s body and crushing the low-level zombies in front of it, creating a false sense of space in the already cramped tunnel.
Theresa’s focus sharpened as she held the plate, every muscle in her body attuned to the rhythm of the battle.
After enduring several assaults, she began to gauge the Level 6 zombie’s power. It was formidable, but she estimated it to be roughly one-fifth of her own strength.
