A sound, deep and unearthly, cracked across the sky — like the world itself had been struck with a sledgehammer. The stars flickered, then vanished behind creeping waves of ash and violet light. A fracture spread across the heavens, jagged and violent.And from that wound in the sky... they fell.Shapes. Twisted. Wrong. Crawling, jerking — no longer human.But inside a secluded estate tucked behind electronic gates and manicured hedges, the world still slept.Ryan stirred beneath the sheets, tangled in warmth. Jane Blackwood lay beside him, her breath calm and even. For a fleeting moment, the illusion held.Then—Bang! Bang! Bang!“Ryan!” Maggi’s voice, sharp with panic. A second slam, louder. “Open the door! Now!”Ryan groaned, still half-dreaming. “What the hell’s going on…”He slid out of bed, eyes heavy, limbs slow. When he opened the door, Eleanor nearly collapsed into him. Her hands were streaked with blood, her eyes wild.“They’re here,” she whispered. “The sky cracked open. Something came through. People are changing. Dying. Tearing each other apart—Ryan, this isn’t a dream. This is real. It’s happening.”He turned, pulse hammering. “Get dressed. We’re leaving.”Outside, the world had ended.And the dead had begun to rise.He reached for his clothes, yanking on a shirt. But just as he stepped toward the hallway. The ceiling of the household collapses on their bodies and they died instantly but the pendant given to him by his mother started flickering and next second, In the world unlike Earth, Ryan instantly opens eyes with a gasp and when he sees himself in the mirror. He got reincarnated in another world.Disclaimer : This is a work of fiction. Names, characters, places, events, and incidents are the products of the author’s imagination or are used fictitiously.
