My favorite story (revision)

Just then, a huge and high-powered cannonball came flying through the air. Rolling thick smoke drifted in the air, like a wild beast, tearing open a big hole in the sky. It dived from the sky like an eagle to catch its prey and landed about one hundred meters from where they stood. They both hastily ran in opposite directions: Ben for the thick woods, and Jim for the tall building. Jim jumped up on that high wall, and climbed like he never had before. He was so light, like a monkey freely shuttling through the woods. And there was the doctor in the doorway, very happy to see them alive.------TREASURE ISLAND
