"Clip-clop, clip-clop," the urgent sounds of hoofbeats echo through the nighttime sky, reverberating over the open plains near the City of Knowledge. Five swift horses race in a line along the main road. Under the waxing light of dawn, their shiny, sweat-soaked bodies reflect glimmers of light. The riders atop the horses were covered in a layer of dust, their faces streaked with muddy lines from sweat. However, they never once relaxed their focus on controlling their mounts, making every effort to maintain the same speed and stay within the line.
