Treasure by David week 23

Another day in the ship. My crew and I sailed around the ocean looking for coins, gold, treasure, anything really. There were rumours of this lost city. So we sailed north to find it. We came across a place with treasure everywhere. So I put my gear on and went down for a closer look. The rest stayed on deck. I stood on the pavement and reached for the gold. I looked up to see our ship sinking but there was a ladder leading up to a red treasure chest. I got it and swam off only to see a rescue boat. We were saved.
