Several people are flying in a hot air balloon. Suddenly, the balloon broke and kept falling. Below is a piece of Wang Yang sea. Just when they were completely desperate, the balloon suddenly drifted to an unknown desert island, and several people had to settle down on the island.
After hard work, they finally have a stable home. Several people do their jobs and live in perfect order. Among them, they also found a "savage", who was originally stranded on this desert island, so they lived together.
Then they face a serious problem. A group of pirates want to land on this nameless desert island. Five pirates of Pioneer had already come up to explore the road, but the pirate ship was sunk by a mine laid by someone, and the pirate leaders Bob and Harvey were also killed.
Their peaceful life was destroyed by five pirates stranded on a desert island. Just as they were helpless, five pirates were mysteriously killed. Later, they finally met the "mystery man", who turned out to be Captain Nemo. Captain Nemo told them to run away as soon as possible. This desert island is about to erupt and the whole island will sink. But Captain Nemo said he was old and dying, and he didn't want to leave.
So several people made a boat overnight and set sail. When they reached a safe place, the volcano erupted and the nameless desert island sank, leaving only a pile of rocks above sea level. This is Captain Nemo's grave.
