When night fell, the city became quiet, and only the sound of traffic was still noisy. A young woman was walking through a busy street with a black puppy in her hand. Her face was pale and her expression was tired, as if she had done something long and tedious all day. The puppy wagged its tail as if it was talking to the girl, but the girl couldn't hear a word. The girl's house was not far away, but she did not want to go home today. She suddenly realized that she seemed to be lost. She began to worry, not knowing how to get home. As night fell, she felt lonely and helpless, as if the whole world had left her. At this moment, she heard a voice. It was a familiar voice. She had heard and experienced this voice before. This voice told her that she could return to her home in a special way. However, she needed to find a way to prove that the voice was real and not just an illusion. Thus, she embarked on an adventure to find her way home. She would face many difficulties and challenges, but she believed that as long as she persevered, she would find a way to go home.
