"Woof woof woof, woof woof woof," the resounding barks merged into one, as three sleds whizzed across the vast snowfield. The snow sled's blade left neat marks on the smooth snow, stretching from the distance. All three sleds were of medium size, pulled by twelve giant white dogs arranged in three rows. Each sled could accommodate one driver and two passengers, with the driver standing in front to control the sled while the two passengers sat facing each other in the rear. The three sleds carried a total of nine passengers, heading towards Snowy Village on the snowfield, searching for two missing young people who had run away from home.
