In ancient times, there was a strange man named Mengda. When he was a teenager, he had an amazing appetite and was extremely powerful. That year's war, officials scraped people's wealth, and the people were miserable. Mengda can't stand oppression, she is determined to resist, but she suffers from no military power and no sword. What should she do? He goes up the mountain to cut wood every day, and always sits on a stone at a loss. One day, an old man with silver beard and white hair came and gave Mengda a stack of paper and a pen. The old man said, "You draw a sword and spear on this paper. By 100 day, the soldiers and horses on the paper will become real people, but don't let anyone know." When the old man finished, he drifted away. From then on, when Mengda came back from work every day, he was locked in the house to write and draw, forgetting to eat and sleep. His mother felt strange and asked him, and he always said, "You'll know in a hundred days." Who knows that on the 99th day, my mother couldn't help it anymore, thinking: It doesn't matter if it's only one day away. Let me see what he drew. So, when Mengda was not at home, he pushed the door and opened the picture box. In a flash, I saw those pieces of paper that had not yet come true, flying out of the house and sticking them on the cliff in front of the village, becoming murals.
