Once upon a time, there were four friends named Lily, Max, Ava, and Ben. They were all in first grade and loved to explore and go on adventures together. One day, while they were playing in the park, they stumbled upon an old book hidden under a tree.

Curious, Lily opened the book and found a strange code written inside. The friends were puzzled and didn't know what it meant. They decided to take the book home and try to figure out the code together.

As they worked on cracking the code, they discovered that it was a secret message left by a group of pirates long ago. The message revealed the location of a hidden treasure on a nearby island. The friends were excited and couldn't wait to go on their very own treasure hunt.

The next day, they set off on their adventure, following the clues in the code. They had to solve puzzles, cross a rickety bridge, and even climb a tree to find the treasure. Finally, they reached the spot where the treasure was buried.

With their shovels, they dug up a chest filled with gold coins and precious jewels. The friends were overjoyed and couldn't believe their luck. They decided to split the treasure equally and use it to buy new toys and books for their school.

As they made their way back home, they couldn't stop talking about their amazing adventure and the secret code that led them to the treasure. From that day on, they were known as the brave adventurers who solved the mystery of the secret code.

The friends promised to always stick together and go on more exciting adventures in the future. And who knows, maybe they'll stumble upon another secret code and go on another thrilling journey. The end.
