Ocean of miracles

There was an old man who lived his entire life on a lonely island in the middle of an ocean. He became one with sea creatures, hunting fish to eat, swimming with dolphins to look for rare items hidden in the bottom of the ocean.
He lived there with his wife and his kid.
The kid grew up to be a fine hunter with high sense of adventure.
One day, He wanted to look for another island. He sat sail on a warm calm night and suddenly, He was hit by thunder.
He found himself in a far away land.
