In a quiet British town, there lived a little girl named Lily. She was a child full of curiosity and imagination, and every night she would lie by the window looking at the night sky.
One night, when Lily looked out of the window as usual, she was astonished to find that the moon had turned blue. The blue moonlight spilled onto the earth, making everything seem dreamy. Lily was so excited that she put on her shoes and decided to go out and explore this magical night.
Lily ran and ran, and came to the town's garden. The flowers in the garden shone with a strange light under the blue moonlight, as if greeting Lily. She saw a little rabbit. The rabbit's eyes also reflected the blue moonlight. It didn't seem afraid of Lily at all. Instead, it seemed to be waiting for her. Lily walked gently towards it, and the rabbit hopped and led Lily deep into the garden.
They came to a big tree. There was a large tree hole in the tree. A faint blue light flickered inside the hole, as if some secret was hidden there. Lily hesitated for a moment, but her curiosity overcame her fear. She followed the rabbit and crawled into the tree hole. Inside the tree hole was a long passage, and the walls were painted with all kinds of strange symbols and patterns.
After passing through the passage, Lily arrived at a magical world. There were countless glowing orbs floating in the sky, and there were all kinds of wonderful creatures on the ground. Some creatures were as soft as clouds and could float in the air; some were as transparent as crystals, shining with charming light. Lily was so happy that she ran around in this world. She played with these creatures and felt the wonder of this world.
While playing, Lily met a blue elf. The elf had transparent wings and blue hair, and it greeted Lily with a clear voice. Lily talked with the elf. The elf told Lily that the blue moon was a very special moment, which only occurred once every hundred years. At this moment, the gate to this magical world would open.
After playing for a long time, Lily noticed that the light of the blue moon began to fade gradually. The elf told Lily that she had to go back because when the light of the blue moon disappeared completely, the gate to this world would close. Although Lily was very reluctant to leave, she knew she had to go. She said goodbye to the elf and those magical creatures one by one, and then followed the rabbit back to the garden along the tree - hole passage.
When Lily got home, the blue moon had returned to its normal color. But Lily knew that this magical night would stay in her memory forever. She lay in bed and fell asleep with full of memories.
