Once upon a time, there was a family where mother and son lived together. The child is called Little Black Dragon.

The little black dragon goes up the mountain to cut the grass every day, picks it up and sells it on the street, barely surviving for mother and son.

One day, the little black dragon went to a place called Haiyan Dam to cut the grass. There was a very lush grass in the dam, and it happened to be a pick.

The strange thing is that if the hay is cut in the morning, it will grow in the afternoon; if it is cut in the afternoon, it will grow back the same as before the next morning.

The little black dragon thought, it was better to dig this fluffy grass to the door of the house and plant it, so as not to run away.

The little black dragon told his mother about this idea, and took the hoe to dig. Dig, dig, and suddenly dig a bright bead.

The black dragon took the bead and hurried home to tell his mother.

My mother looked right and left, very happy. She put the beads carefully in the rice cabinet. While cooking, mother opened the cabinet and saw that the only bit of rice had become a full cabinet of rice.

She took some to cook, and the next day, it was still a cupboard full of rice.

The mother put the beads in the box with a few coins in it. When she opened the box the next day, it was full of silver again. This made the mother and son, who had been poor for many years, very happy.

One day, the little black dragon was playing with his friends with an orb in his arms. While having a good time, the bead fell out of his arms.

When the little friends saw it, they immediately competed with each other underground, all wanting to take a good look at this orb.

The little black dragon was anxious, pounced on the bead, grabbed the bead, and held it tightly in his hand.

The companions refused to give up and surrounded the little black dragon together to grab the beads.

The little black dragon was anxious and quickly put the bead into his mouth. Unexpectedly, with a "grunt", the bead swallowed his stomach. After a while, the little black dragon only felt dry and thirsty. He ran home and drank all the water in the water tank, but still couldn't quench his thirst.

Black Dragon's mother hurriedly went to pick water for him to drink. Choose one, Black Dragon drinks one; choose two, Black Dragon drinks two…

The black dragon mother was tired, and the little black dragon was still very thirsty.

Mother Heilong had no choice but to say, "My son, I really can't afford it. If you're still doing well, go drink in the river!"

The mother and son came to the river, and the little black dragon went down to the river to drink water. As he drank, the black dragon's body grew and grew. After a while, a crown grew on his head, and a horn grew. A long tail grew on his butt.

The little black dragon really turned into a dragon.

The black dragon mother was frightened, and she said to the black dragon in a trembling voice: "Child, if you are a dragon, go to the big river and the sea! Don't scare the villagers here."

The black dragon could not bear to leave his mother, and was afraid of scaring his mother and the villagers. He turned back step by step and went down the river.

The black dragon looked back at his mother twenty-four times, and twenty-four pools formed on the river. People called these deep pools Wangniang Pond.
