One sunny weekend, Lin Yue walked into an old bookstore. The store was filled with the faint fragrance of books and ink. When she was rummaging through the bookshelf in the corner, an old book with a beautiful cover attracted her. When she opened the book, a yellowed postcard fell down, which read: "Meet the person you meet among millions of people. In the wilderness of endless time for millions of years, there is no step too early or one step too late." The handwriting was strong and powerful, and there was a signature "Shen Yi" at the back. Lin Yue didn't know why, but she became very interested in the name and the postcard. She put the postcard into her bag and left the bookstore with the book.
That night, while Lin Yue was sorting out books, she saw the postcard again. Suddenly, a white light flashed in front of her eyes, and she was in a strange place. The surrounding buildings are retro in style, and people on the streets wear costumes from the Republic of China period. Lin Yue panicked and had no idea what was happening.
