The princess arrives and the prosperous Tang Dynasty begins

Under the guidance and encouragement of the fairy Chang'e, Lin Xiao and Li Xuan's journey continues to move forward. Their goal is not only to explore the fantastic events of the Tang Dynasty, but also to find a way back to the modern times. One day, they decided to go to a valley where a legendary dragon lives. The dragon here not only has powerful strength, but also guards many ancient secrets.

Lin Xiao and Li Xuan followed the guide and carefully crossed the lush forest, and finally arrived at this mysterious valley. The scenery here is like a fairyland, surrounded by mountains and filled with clouds and mist, making people feel as if they are in a dream.

As they went deeper, Lin Xiao began to feel that the air around her seemed to become unusually active, filled with a strong energy fluctuation. This feeling made her feel excited and expectant, but also nervous and uneasy. She couldn't help but wonder what this powerful energy meant? Was there some kind of danger or opportunity hidden? Li Xuan seemed calmer. He was always alert and observed everything around him.

The road in the valley was bumpy and uneven, and there were occasional slight noises coming from the bushes on both sides, which made people feel a little creepy. Lin Xiao tightly grasped the sword in her hand, her heartbeat accelerated, and her palms sweated slightly. However, she did not retreat, but moved forward more firmly. Because she knew that only by bravely facing the unknown could she find the real answer.

At this moment, a low roar suddenly came from the front, shaking the whole valley. Lin Xiao and Li Xuan stopped and looked vigilantly in the direction of the sound. They saw a huge black figure slowly walking out of the mist. It was huge, with clear muscle lines, and exuded a palpitating breath.

Deep in the valley, they met an old man with white hair and beard and bright eyes. The old man claimed to be the guardian of this place. He warned Lin Xiao and Li Xuan that although the dragon was powerful, it was also extremely dangerous and they needed to be careful. Lin Xiao and Li Xuan expressed their respect to the old man and said that they were willing to accept any test just to see the dragon.

The old man was moved by their determination and decided to help them. He led Lin Xiao and Li Xuan through the valley and came to an open grassland. In the middle of the grassland was a huge rock with complex runes engraved on it, emitting a mysterious light. The old man told them that these runes were the key to open the dragon's realm, and they needed to work together to unlock them.

Lin Xiao and Li Xuan stared at the rock in front of them, constantly recalling the method taught by the old man. They concentrated on observing the arrangement and structure of the runes, trying to find the rules from them. Although it was not easy, they did not give up, but calmed down and studied it carefully.

As time went by, beads of sweat appeared on their foreheads. Finally, after some effort, they found the solution to the first rune. Then, the second, the third... runes were successfully deciphered one by one. Every time they solved a rune, they could feel a surge of mysterious power.

When the last rune was unlocked, the entire rock suddenly began to vibrate violently. Lin Xiao and Li Xuan watched all this nervously, not knowing what would happen next. At this moment, a dazzling light shot out from the rock, illuminating the surroundings like daylight. In the light, a huge light gate slowly emerged.

Looking at the spectacular scene before them, Lin Xiao and Li Xuan were filled with excitement and anticipation. They knew that this light gate was the entrance to the interior of the ruins. Could they successfully enter it, and what challenges would they face? With all sorts of questions, they took firm steps towards the shining door.

The old man said: "This light gate leads to the dragon's realm. Once you enter, you will face real challenges. Remember, be fearful and move forward bravely."

Lin Xiao and Li Xuan took a deep breath and stepped into the closed door. A white light flashed before their eyes, and when they opened their eyes again, they found themselves in a vast cave. The walls of the cave were inlaid with countless glittering gems, reflecting colorful light. From deep in the cave, a low roar came, shocking people.

The two walked along the cave, gradually approaching the source of the roar. Finally, they came to the deepest part of the cave, where a huge dragon was lying. The dragon's scales shone in the light, and its eyes were like two huge gems, emitting a majestic light.

Lin Xiao and Li Xuan were shocked by Long's momentum, but they did not retreat. Lin Xiao stepped forward and said respectfully: "Dear Long, we are here to seek your help and guidance. We hope to learn your strength and use it to protect ourselves and others."

The dragon lowered its head, examining them. Its voice was deep and powerful, echoing throughout the cave: "Why do you think you are worthy of my power?"

Li Xuan said firmly: "We have experienced many challenges and difficulties along the way, but we have never given up the pursuit of kindness and justice. We believe that as long as we have good intentions and move forward bravely, we will be able to overcome all difficulties."

The dragon nodded with satisfaction and said, "Very good, your courage and determination have impressed me. I will teach you some ancient dragon skills, but you must understand that strength is not only for fighting, but also for protecting and helping others."

The dragon began to teach Lin Xiao and Li Xuan some basic dragon skills. These dragon skills include how to use the power of dragon to enhance one's own abilities, how to use the roar of dragon to intimidate the enemy, and how to use the wisdom of dragon to solve various problems. Lin Xiao and Li Xuan studied seriously and felt the power and magic of these dragon skills.

Under Long's guidance, Lin Xiao and Li Xuan's abilities have been significantly improved. They not only learned how to use the power of Long, but also learned how to control this power and not let it get out of control. Long also taught them some ancient wisdom, allowing them to be more calm and rational when facing difficulties and challenges.

After the study, the dragon said to them: "You have mastered the dragon arts. Now it is time to accept the final test. At the other end of the valley, there is a land eroded by the power of darkness. You need to use the knowledge and strength you have learned to restore that land to its original state."

Lin Xiao and Li Xuan accepted the challenge, and with the dragon's blessing and guidance, they headed to the other side of the valley. It was indeed as the dragon said, filled with a dark force, the land was withered, and the sky was dark. They felt a strong sense of oppression, but did not retreat.

The two used the dragon arts they had learned to expel the power of darkness. Their figures flickered in the darkness, like two rays of light. Wherever they went, the darkness gradually dissipated and the land regained its vitality. After some efforts, the dark power of the entire area was finally completely expelled, and the sun shone on the earth again.

Their success brought new vitality to the entire valley. The dragon appeared again and praised them: "Your performance proved your courage and wisdom. Remember, true power lies in how you use it, not just in having it. Continue your journey and use your power to help more people."

Lin Xiao and Li Xuan thanked Long gratefully and continued their adventure with new strength and wisdom. They knew that this experience not only made them gain great power, but also made them understand the true meaning of power.
