Modern youth Bu Fan was a taxi driver who, in an unexpected traffic accident, traveled through time to the 1960s, becoming the pillar of a impoverished rural family. Facing mud-brick houses, empty rice jars, and a starving wife and daughter, he was feeling desperate when he discovered that he could freely travel back and forth to an interstellar space supermarket with infinite supplies. From a bag of corn to a few wild rabbits, he cautiously improved life for his family, holding up a piece of the sky with the space supermarket in an era of material scarcity. From material scarcity to material abundance, he ultimately made a fortune in reality and became a powerful warlord figure.
