There is Shangzhangjia Village in the east of Dinghai City. There is a 100 meterhigh Lion Mountain behind the village, and there is a natural ancient cave in the south of the mountain. The local people collectively call it the "One-horned Dragon Cave." Legend has it that there used to be a one-horned dragon wrapped in this cave, which was very ferocious and cruel, and often turned into a beautiful man. He broke into the house in the middle of the night to make trouble.

This one-horned dragon turned out to be the youngest son of the Dragon King of the East China Sea. He was very ugly, but he especially liked to seek flowers and ask for willows. Some beautiful fish girls and shrimp girls in the aquarium were scared to death when they saw him. Later, he felt that he could no longer find the girl he liked in the aquarium, so he came to Shangzhangjia Village and became a white-faced scholar, teasing girls everywhere.

One day, when he passed Lion Mountain, he came to a steamed bun shop at the foot of the mountain, so he went into the shop to rest and buy a few cages of steamed buns to fill his stomach. This steamed bun shop was opened by a widow surnamed Li. Widow Li was in her thirties, had no parents-in-law, no children, and lived alone selling steamed buns. Seeing that she was very beautiful, the one-horned dragon came to the store every day to buy steamed buns to eat, eat steamed buns and chat with Widow Li.

After a long time, Widow Li was seduced and became the concubine of the one-horned dragon. The one-horned dragon did not want to go back to the Dragon Palace, so he found a cave on the south side of Lion Mountain, went to sleep in the cave during the day, and slipped into the village at night to hang out with Widow Li. Later, as Widow Li grew old and faded, the one-horned dragon began to neglect her and went to the village to find another love.

Once, a girl named Zhao Jiaojiao passed by Upper Zhangjia Village. The girl had learned a good martial arts, and she ran in rivers and lakes, traveling south and north, specializing in chivalrous affairs. After a day's walk, she was tired and hungry, so she came into the store to buy steamed buns to satisfy her hunger. It happened that the one-horned dragon was also in the store. The one-horned dragon saw that Jiaojiao was young and beautiful, and his mouth was three feet long. He transformed into a shop assistant and sent a cage of hot buns to Widow Li, secretly spilling a bag of perspiration medicine into the buns.

Jiaojiao's stomach growled with hunger, and she ate it as soon as she caught it. After some time, she ate all the buns in a cage, but she also fell asleep in a daze. The one-horned dragon was not happy, so he picked up Jiaojiao and left. Back in the cave, the one-horned dragon showed its true nature, blowing a cool breeze at Jiaojiao with a wide smile, shouting, "Wake up, girl, wake up!"

Jiaojiao yawned, opened his eyes, and looked around. There was a black monster standing in front of her, knowing that she had suffered a loss, and sharply asked, "What are you? How dare you tease a girl!"

Seeing the girl wake up, the one-horned dragon smiled and said to the ground: "Don't be afraid, girl, I am the seventh prince of the Dragon King of the East China Sea, you and I are destined for this life. When the girl enters my cave, she will enjoy endless glory and wealth!"

After all, Jiaojiao was a heroine who had crossed rivers and lakes and seen the world. Hearing this monster's words, although her heart was afraid, she was very calm on the surface. She thought that since she was in the clutches of the devil, it was impossible to escape at once. Although she had learned martial arts and had a golden dart with her, this monster was covered in iron-scaled armor, and it was difficult for the golden dart to break its flesh and skin. Now she could only slowly look for an opportunity to subdue the evil dragon.

So he said to the one-horned dragon: "Lord Dragon, Lord Dragon, you are a Dragon Immortal and I am a mortal, how can you get married? If the old Dragon King knows and says that you violated the rules of the Dragon Palace, won't it make you suffer?"

Hearing this, the one-horned dragon said angrily, "The seven fairies in the sky are not afraid to violate the rules of heaven and dare to marry Dong Yong of the mortal world. Can't my seventh prince marry a mortal woman as his wife?"

Jiaojiao said again, "Lord Dragon, Lord Dragon, it's a pity that you are wearing iron-scaled armor all over your body, and you have any flesh to see. It's difficult to get married!"

When the one-horned dragon heard that the girl was moved, it danced happily and said, "How difficult is this? As long as I take off the three dragon scales at the bottom of my throat, I can become a beautiful man in the flesh of an ordinary person. I gave you buns in the steamed bun shop just now, didn't you see it?"

"Oh, the waiter who delivered the buns just now was your Lord Long? He's quite handsome." Jiaojiao then whispered: "Lord Long! Are you really that capable? I still don't believe it. As the ancients said, what you say is unfounded, what you see is true. If you have real ability, show me again!"

"You still don't believe me? Then I'll change it for you on the spot!"

As the one-horned dragon spoke, he raised his claws and peeled off the three dragon scales at the bottom of his throat. Jiaojiao saw that the one-horned dragon was unsuspecting of himself, and when he stretched out his neck to peel off the dragon's scales, Jiaojiao quickly flew a golden dart, which was unbiased and stabbed the one-horned dragon's seven-inch throat. The one-horned dragon let out a long roar, and two dragon-eye droplets protruded like pig urine bubbles. The dragon's tail slammed and slammed into the stone cave, and it died.
