As the group went on with their journey, the absence of a vehicle meant they would have to rely on their own endurance to reach City T. Aegis, their trusted robotic companion, informed them that it would take approximately two days of travel on foot.
Drey looked at his friends, concern etched on his face. "We'll need to pace ourselves and conserve our energy. Two days of walking won't be easy, but we can do it. We already walked like an eternity back at City O."
Lana nodded, determination shining in her eyes. "We've faced worse, Drey. We'll make it through."
Their trip proceeded smoothly throughout the morning and into the afternoon. They encountered the usual hordes of zombies, dispatching them with skill and precision. The group had become a well-oiled machine, seamlessly working together to face any threat that crossed their path.
However, as they ventured further, they came across something they had never seen before—a mutated zombie engulfed in flames. Its charred skin crackled and glowed with an eerie light, giving off an intense heat. The sight sent a shiver down their spines.
Drey's eyes widened in surprise and curiosity. "What in the world is that?" he muttered to himself.
Rachel, her voice laced with concern, spoke up. "Drey, what's happening? Why is it on fire?"
Aegis, ever knowledgeable, chimed in. "This is a new mutation, a fire-infused zombie. It can spit fire as an attack, making it dangerous at a long range."
Drey's brows furrowed as he processed the information. "Fire-spitting zombies? This just keeps getting more challenging."
Unwilling to let the group face unnecessary risks, Drey made a quick decision. "I'll take care of this one alone. The rest of you stay back."
As the others stepped back, Drey readied his plasma bow, a weapon capable of firing energy arrows. With the precise aim and swift movements, he unleashed a volley of plasma arrows, piercing through the fiery zombie's defenses and reducing it to ashes.
Drey's friends watched in relief as he swiftly eliminated the threat. Lana approached him, her voice filled with affection. "Drey, that was amazing! You handled it like a pro."
Drey smiled, though concern lingered in his eyes. "Thanks, Lana. But did you see that? Fire-infused zombies... It means the mutations are becoming more complex. We need to be on guard."
Shauna interjected, her voice tinged with worry. "If they can control fire, what other elements might they harness? This is getting dangerous."
Drey nodded in agreement. "Exactly. We have to stay alert and be prepared for anything that comes our way. Our survival depends on it."
With a sense of caution, the group proceeded their trek toward City T. They knew that the appearance of fire-infused zombies was a sign that the threat they faced was evolving. They walked with a heightened sense of vigilance, ready to face whatever monstrosities lay ahead.
As they pressed forward, they couldn't help but wonder what other elemental surprises awaited them on their path. Concern mingled with strength in their hearts, with Drey'a advanced technological weapons, they had a fighting chance against the ever-evolving forces of the undead.
