A 9000 millimeter journey

The parents of the two siblings on the small slope are not at home, leaving the siblings alone. After measuring the distance from the door to the balcony, they discovered it was as long as 9000 millimeters. Suddenly, their bodies shrank, and the house that was once palm-sized in their eyes became as big as the world! They embark on a mission to retrieve lunch prepared by Aunt Gu from the community, a journey that spans a distance of 9000 millimeters. Along the way, they encounter the King of the Wool Mouse, pass through the Wooden Leg Forest, navigate the Shoe Maze, and even stumble upon the uncharted "Lost Paradise."
