In a distant country, there is a mysterious and terrifying legend. Legend has it that there is a cursed castle that towers into the clouds. The black city walls exude a gloomy atmosphere. The castle is filled with dark magic, like a huge vortex that engulfs all approaching lives in endless fear.

This castle was once a symbol of a prosperous kingdom. However, a sudden disaster befell. An evil magician coveted the treasures and power in the castle and cast dark magic, imprisoning the king and queen in the castle, and the princess was also trapped deep in the castle. The entire kingdom fell into despair and chaos. People fled in panic, fearing being devoured by the dark magic in the castle.

In a small village in this country, there lives a brave and kind knight named Yalan. Yalan lost her parents since childhood and was adopted by an old knight. Under the guidance of the old knight, she learned horseback riding, archery, and swordsmanship and became an excellent knight. Yalan heard the legend of the castle, and her heart was filled with a sense of justice and mission. She decided to embark on a journey to rescue the trapped princess and restore peace and prosperity to the kingdom.

Yalan rode her steed, crossing thick forests and steep mountains. Along the way, she encountered various dangers and challenges. Once, she encountered a group of fierce wolves. The wolves bared their fangs and claws and pounced on her. Yalan was not afraid at all. She drew her long sword and engaged in a fierce battle with the wolves. In the battle, Yalan showed extraordinary courage and skill and finally succeeded in repelling the wolves.

However, Yalan knew that relying solely on her own strength was far from enough to rescue the princess. She needed to find more powerful strength to confront the evil magician in the castle. During an adventure, Yalan came to an ancient temple. In the temple, there is a mysterious statue enshrined. The statue exudes a powerful aura. Yalan prayed piously to the statue, hoping to get the guidance and help of the gods.

Just as Yalan was praying, a dazzling light suddenly appeared in the temple. In the light, a huge Kang Jinlong slowly emerged. Kang Jinlong's body is winding, and its scales are shining with golden light. Its eyes reveal majesty and wisdom. Yalan was stunned by the appearance of Kang Jinlong. She didn't know whether this golden dragon was friend or foe.

Kang Jinlong looked at Yalan and said, "Brave knight, I feel your justice and courage. The goal you pursue is great, but the difficulties you face are also great. The evil magician in the castle has powerful dark magic. You cannot defeat him with only your own strength. I can endow you with powerful strength, but you must promise me one condition."

Yalan replied without hesitation, "Respected Kang Jinlong, please tell me what the condition is. As long as I can rescue the princess and restore peace to the kingdom, I am willing to pay any price."

Kang Jinlong said, "My condition is that you must use your strength to protect the weak and maintain justice and must not abuse my strength. If you violate this condition, I will take back my strength and punish you."

Yalan solemnly promised, "I will definitely abide by your condition and use my strength to protect the weak and maintain justice."

Kang Jinlong nodded, then opened his mouth and spat out a golden bead. The bead emits a powerful light and is suspended in front of Yalan. Kang Jinlong said, "This bead contains my strength. You can wear it on your body, and it will give you strength when you need it. However, you must remember that the greater the strength, the greater the responsibility. You must use my strength carefully and must not let it fall into the hands of evil people."

Yalan took the bead and said gratefully, "Thank you for your help, respected Kang Jinlong. I will definitely live up to your expectations and use your strength to rescue the princess and restore peace to the kingdom."

Wearing the bead, Yalan continued on her journey. With the help of the power of the bead, Yalan became stronger. She is faster, stronger, and more proficient in swordsmanship. Yalan overcame all obstacles along the way and finally arrived in front of the cursed castle.

The castle gate was closed tightly, and the door was engraved with mysterious runes. Yalan knew that these runes were magic traps set by the evil magician. Once touched, they would trigger powerful magic attacks. Yalan carefully observed the gate, looking for a way to crack it.

Just when Yalan was at a loss, the bead suddenly emitted a ray of light. In the light, some mysterious symbols and patterns appeared. Yalan carefully observed these symbols and patterns and found that they were an ancient magic language. Yalan had seen this language in an ancient magic book before. She knew that these symbols and patterns were the key to cracking the magic trap on the gate.

According to the instructions of the magic language, Yalan gently touched the runes on the gate. The runes flashed and then disappeared. The gate slowly opened, revealing a dark passage. Yalan walked into the passage without hesitation. She knew that the princess was waiting for her rescue at the end of the passage.

The passage was filled with a dark magical atmosphere, and the walls were flashing with eerie lights. Yalan advanced carefully, holding the long sword tightly in her hand, ready to deal with possible dangers at any time. At the end of the passage, Yalan finally saw the princess. The princess was imprisoned in a huge magic cage, and the cage was engraved with dark runes.

The moment Yalan saw the princess, her heart was filled with joy and excitement. She knew that her efforts had not been in vain, and she finally found the princess. However, Yalan also knew that she had not completely succeeded. She had to defeat the evil magician to truly rescue the princess.

Just when Yalan was about to rescue the princess, the evil magician appeared. The magician was wearing a black robe and holding a black magic wand in his hand. His eyes were flashing with evil light, and a ferocious smile appeared on the corner of his mouth.

The magician looked at Yalan and sneered, "Do you think you can rescue the princess? You are too naive. This castle has been shrouded in my dark magic. You cannot escape."

Yalan looked at the magician without fear and said, "Evil magician, your rule is about to end. I will use my strength to defeat you, rescue the princess, and restore peace to the kingdom."

The magician laughed loudly and said, "Just by you? Do you think you can defeat me with the power of Kang Jinlong? You are too naive. My dark magic is invincible. You cannot defeat me."

As he spoke, the magician waved his magic wand and released a powerful dark magic attack. The magic attack was like a black lightning bolt, striking at Yalan. Yalan quickly dodged the magic attack while drawing her long sword, preparing to counterattack.

Yalan knew that she could not confront the magician head-on. She had to find the magician's weakness to defeat him. During the battle, Yalan found that although the magician's magic attack was powerful, his body was relatively weak. Yalan decided to take advantage of this weakness and attack the magician.

Yalan skillfully dodged the magician's magic attacks and then took the opportunity to approach the magician. When she was close to the magician, she suddenly launched an attack. Yalan's long sword was like a lightning bolt, stabbing at the magician's chest. The magician looked at Yalan in horror. He did not expect Yalan to be so brave and witty.

The magician tried to dodge Yalan's attack, but it was too late. Yalan's long sword pierced the magician's chest. The magician let out a scream and then fell to the ground. With the fall of the magician, the dark magic in the castle gradually disappeared.

Yalan successfully defeated the evil magician and rescued the princess. The princess looked at Yalan gratefully and said, "Thank you, brave knight. You are our hero. You have saved our kingdom."

Yalan smiled and said, "This is what I should do, princess. I just fulfilled my promise and used my strength to protect the weak and maintain justice."

Yalan took the princess and left the castle and returned to the kingdom. The people of the kingdom cheered. They were proud of Yalan's bravery and wisdom. The king held a grand celebration ceremony for Yalan to honor her achievements.

In this process, Yalan also had a deeper understanding of Taoist thought. She understood that strength is not for showing off and conquering but for protecting the weak and maintaining justice. She also understood that justice and courage are the keys to defeating evil. Yalan decided to spread Taoist thought to more people and let them understand the importance of justice and courage.

From then on, Yalan became the guardian of the kingdom. She used her strength to protect the people of the kingdom and maintain the peace and prosperity of the kingdom. And the power of Kang Jinlong has always been with her, becoming a powerful backing for her to overcome difficulties.

In the distant country, the legendary story of Yalan and Kang Jinlong will be passed down forever, inspiring people to bravely pursue justice, protect the weak, and use their strength to create a better world.
