Under the bright moon in the sky, loess was piled high, and a man stood in front of the wordless monument with a sword on his back. When the wind suddenly rose and the dust was flying, he bit off his middle finger and swung it like a flying pen. Six blood-red words "Looking back is the end of the world" appeared on the wordless tablet. He drew his sword and inserted it into the center of the high mound. His long sleeves rolled up the dust to seal the sword hole. He looked up until the yellow moon disappeared.
