Brief introduction of content plot

This book mainly tells the story of the submarine Nautilus. 1866, a monster suspected to be a narwhal was found at sea, and Professor Pierre Aronnax and his servant Conseil were invited to take part in the hunting. During the chase, they and the harpooner Ned Land unfortunately fell into the water and landed on the monster's back. They found that this monster is not a narwhal, but a submarine with wonderful structure.

This submarine was secretly built by Nemo on a desert island in the middle of the ocean. It has a solid hull and uses seawater to generate electricity. Captain Nemo invited Pierre Aronnax to travel to the bottom of the sea. Starting from the Pacific Ocean, they passed through coral islands, Indian Ocean, Red Sea, Mediterranean Sea and Atlantic Ocean, and saw many rare animals and plants and strange sights in the sea.

On the way, I also experienced many dangers such as stranding, indigenous siege, fighting with sharks, iceberg road closure, octopus attack and so on. Finally, when the submarine arrived at the Norwegian coast, the three left without saying goodbye and returned to their hometown.
