As the saying goes, Even a shrimp dares to dupe the dragon when it is in the shallow water;a tiger may even be teased by a dog when it leaves the remote mountains and comes to the bright and flat area. But how can this dragon appear in the shallow water? This is the story I want to tell today.

During the reign of Emperor Kangxi in the Qing Dynasty, there was Tao Jingyang in a village in Province. There was a pond at his door, which was dug up by his ancestors to raise fish. In his generation, he started the business of raising fish and selling fish. One night in the summer of that year, it rained heavily, lightning flashed, and suddenly a thunder struck the pond.

Tao Jingyang saw the pond outside the door was struck by lightning at home, as if there was a giant thing falling into the pond with a loud crash. Tao Jingyang cried out in his heart. He didn't know how many carp would be burned! The next day, he arrived at the pond and saw no dead fish on the water.

Tao Jingyang felt very strange when he walked around the pond. He looked carefully at the water surface and found a long, dark thing lying on the bottom of the water. Tao Jingyang found a boat for fishing and rowed to it. He poked it with a bamboo pole. It suddenly twisted and scared Tao Jingyang, who couldn't stop shouting!

Suddenly, the thing turned up and surfaced. It was a black Eastern dragon head! The dragon head is only the size of a dog's head, but the dragon horn and beard are clear, which is really the appearance of a dragon. Tao Jingyang was too scared to move. Black Dragon said, "I'll borrow some carp from your pond to rest and heal. Please don't take it amiss."

Tao Jingyang stammered, "Are you... are you a dragon?" "I'm a dragon. Last night I was accidentally injured by the thunder in the sky. I just lurked here. Please don't publicize it." Tao Jingyang was relieved when he saw that the dragon said that it was not like an evil beast. "Please feel at ease," he said. "But since you are a divine dragon, how can you still be hurt by thunder?"

The black dragon said: "Only because I ate the thousand year old wine of the Dragon King in the East China Sea and flew over here drunk and met a thunderstorm, I was accidentally injured. I dived into your pond and turned it into the size it is now. I ate the carp that was killed by lightning last night. Now I'm taking a rest and healing. It only takes three days to leave." Tao Jingyang then knew that the black shadow that fell into the pond last night was the black dragon.

After the Black Dragon basked in the sun for a while, Tao Jingyang asked him to swim to the place where the willows on the bank of the pond could not be easily seen. He also told him to eat fish if he wanted. Black Dragon nodded and thanked him for continuing to rest in the water. Tao Jingyang didn't say anything about it. First, he kept his word. Second, he was worried that if he said it, he would be retaliated by Black Dragon.

Tao Jingyang was afraid that the carp in the pond was too small, so he bought a wild big carp from the market and fed it to the Black Dragon, When black dragon ate the carp on the shore, Tao Jingyang said, "Please ask me a question, why can the Dragon fly in the sky without wings?" The black dragon said, "When diving, our body will shrink, and when it's raining, I breathe air into my body and get inflated, then I can fly in sky." Tao Jingyang is hard to understand it.

In the evening of the third day, when the black clouds came and it rained, the black dragon climbed up to the bank. Tao Jingyang saw his full body of it. It was as thick as a human thigh, and ten meters long. Black Dragon kept breathing with his mouth open, and soon his body expanded to ten times its original size, with his internal organs indistinctly visible. The black dragon flew into the sky with a leap, and Tao Jingyang was amazed.

It used to be more than a month ago. It began to rain in the evening, and something fell into Tao Jingyang's yard. Tao Jingyang went out to pick it up and was pleasantly surprised. It turned out that it was a few pieces of gold nuggets with big fists. Looking at the sky, the tail of the black dragon was faintly visible. It was a natural gold nugget that black dragon did not know where to find. Since then, Tao Jingyang has become more and more wealthy by business.
