"My grandmother said that there was a mysterious cave near Zaria," Olivia said. "She said that it was said to be the hiding place of the lost treasure of Nigeria."

Mus'ab was intrigued by this. He had heard stories of the mysterious cave, but he had never been there himself. He decided that it was worth a try and the two of them set off for the cave.

When they arrived, they were amazed by what they saw. The entrance to the cave was huge and it seemed to go on forever. Mus'ab and Olivia looked around, but they couldn't see anything.

Suddenly, Olivia noticed something glinting in the darkness. She reached out and grabbed it. It was a golden necklace with a strange symbol on it.

Mus'ab and Olivia looked at each other in amazement. They had finally found a clue to the lost treasure of Nigeria!

They quickly explored the rest of the cave, but they couldn't find anything else. They decided to take the necklace and continue their search elsewhere.

As they left the cave, they both felt a sense of excitement. They had finally found a clue to the lost treasure of Nigeria! They were one step closer to finding the treasure and solving the mystery.
