Polly and Amir wanted to follow the clues they found. They started a journey deeper into the desert. The sun was very hot above them. They rode on a strong camel. The camel walked with a steady rhythm. The wind sounded like distant music. The desert was full of golden sand and old ruins. Each ruin had a story from Egypt's past. Polly was amazed by the beauty of the desert. The silence of the desert was very powerful. Amir was good at guiding the camel. He told stories from his family. "My ancestors were Bedouins," he said proudly. "They traveled the desert. They knew these sands very well." As the day went on, they saw some old stones. Amir thought these stones marked the lost tomb. The tomb was mentioned in the old writings. Polly felt excited and a bit scared. "The tomb must be here," Amir said. He got off the camel. "We need to find the entrance before it gets dark." The sun was going down. The desert looked magical in the evening light. Polly knew they were close to a big discovery. This discovery could change everything.
