The apocalypse has arrived. Zombies roam freely, mutated beasts wreak havoc, human civilization is on the verge of collapse, and Earth has become a wasteland. The sky seems to be weighed down by a massive lead plate, heavy and suffocating. The once clear, azure sky, a beacon of hope, now presents a despairing gray hue. The sun, the star that once gave Earth light and heat, symbolizing life and vitality, now appears weak and powerless. It struggles to pierce through layers of gloom, only able to cast a few faint rays, like the last gasps of a terminally ill person, laboriously outlining the end of the world.
