After 24 hours, as humans reappear, they would find a world slightly changed: A cityscape that has subtly transformed during their absence. Nature has begun to reclaim the environment, with plants growing through pavement cracks, wild animals exploring urban areas, and cleaner air reflecting a temporary environmental recovery. The scene should show a mix of human structures and emerging greenery, highlighting the brief yet significant changes in the world during their absence and offering a poignant glimpse into a reality where nature starts to heal without human interference.
