Instant level up(Levelling up in an apocalypse)

In a world ravaged by an insidious disease that transformed the infected into savage beasts, humanity teetered on the brink of extinction. Those who succumbed to the infection became nightmarish creatures, viciously attacking any unfortunate soul they encountered.

Yet, amidst the despair, a glimmer of hope emerged. Some individuals, infected by the disease but untouched by its horrific transformation, were reborn with extraordinary powers. These newfound abilities bestowed upon them the means to combat the relentless onslaught of the infected, granting a flicker of light in humanity's darkest hour.

As the survivors huddled together behind towering walls, seeking refuge in an isolated sanctuary, a group of individuals emerged as their leaders. These gifted beings, blessed with the potent force known as Chaos Energy, shouldered the responsibility of venturing beyond the barricades to reclaim their lost homes.

Among those left bereft by the apocalypse, a young boy named Kadori harbored a fervent wish: to join the ranks of the runners, the brave souls who ventured into the treacherous unknown to confront the abominable creatures. His heart ached with the loss of his last living family members, and he yearned for vengeance against the chaos that had stolen his loved ones.

Then, one fateful day, Kadori's dream came to life. Permission was granted for him to step beyond the protective walls, armed with newfound hope and a fierce determination. But destiny is a capricious mistress, and tragedy struck on his very first foray into the hostile wilderness.

Yet, even as Kadori's life hung in the balance, a mysterious force stirred. Whispers of a cryptic message echoed in the desolation:

"[Host has been found.]

[Survive one day alone outside the walls.]

[Reward: Instant Level Up]"

The tale unfolds with the promise of epic struggles, newfound powers, and the enduring spirit of humanity's will to survive. Kadori's journey has only just begun, and the world beyond the walls holds secrets, perils, and the key to humanity's resurgence.
