Chen Fan, a simple farmer, accidentally activated the "Shen Nong Official Road System" when the world was experiencing a severe drought and people were starving to death. From then on, he used heaven and earth as his chessboard and grains as his chess. He grew high-yielding grains and defeated corrupt officials. He gradually climbed from the fields to the top of the court, and finally became a commoner prime minister who was inferior to one person and superior to tens of thousands of people!
