An ordinary old man from a construction site accidentally discovers a light door connecting the past and the present. On one side is a modern construction site full of building materials and machinery; on the other is a poor and backward ancient farmhouse. He travels back and forth between the two worlds, transporting bricks, stones, and supplies. He uses modern goods to improve his ancient family's life, supporting the livelihood of a large family all by himself by moving bricks across worlds.
