Please rewrite Du Mu's "Mountain Journey" into a short story

Du Mu's Journey to the Mountains described the interesting sights and experiences he encountered while walking in the mountains. The following is the story after the rewrite: Once upon a time, there was a young traveler named Li Yun. He had heard that there was a mysterious mountain peak in the depths of the mountains. It was said that there was a magical cave dwelling there that hid countless treasures. Therefore, he decided to head to that mountain to find this cave abode. Li Yun embarked on a long journey through dense forests and steep mountains. Along the way, he saw many strange sights such as strange animals and plants, mysterious caves, and flowing springs. He was excited and curious, wanting to know more. Finally, he reached the peak. He climbed up the steep mountain path and walked step by step toward the cave abode. Along the way, he heard strange sounds and saw some strange figures in the distance, but he was not afraid. He firmly believed that he would definitely find this cave abode. Finally, he reached the entrance of the cave. He walked in and saw a pitch-black cave. He walked carefully until he saw a huge stone door. There were some strange symbols carved on the door. He didn't understand their meaning, but he decided to open the door and take a look. The door opened and he saw a huge cave flashing with all kinds of lights. He felt as if he was in a wonderful world full of surprise and awe. He walked along a path and saw many mysterious sights until he finally reached the treasure. Li Yun found that the treasure was not as precious as he had imagined. Instead, it was some ordinary items and herbs. He was disappointed, but he also understood that the real treasure was not those expensive items, but those that could make you feel the beauty and wonder of life. From that day on, Li Yun no longer pursued those expensive treasures but paid more attention to his own feelings and experiences. He understood that the most important things in life were not money and material things, but health, happiness, and true happiness.
