Seabed***

This book mainly tells the story of the Nautilus submarine. In 1866, a large monster suspected to be a narwhal was discovered at sea. Professor Aronnax and his servant Conseil were invited to join the hunt. During the pursuit, they and harpooner Ned Land unfortunately fell into the water and landed on the monster's back. They discovered that the monster was not a narwhal, but a submarine with a wonderful structure. The submarine was built secretly by Nemo on a desert island in the ocean. It has a strong hull and uses seawater to generate electricity. Captain Nemo invites Aronas to travel to the bottom of the sea. Starting from the Pacific Ocean, they passed through coral islands, the Indian Ocean, the Red Sea, the Mediterranean Sea, and the Atlantic Ocean, and saw many rare animals, plants and strange scenes in the sea. On the way, they also experienced many dangerous situations such as stranding, siege by indigenous people, fighting with sharks, iceberg road closure, octopus attack and so on. Finally, when the submarine arrived at the coast of Norway, the three of them left without saying goodbye and returned to their hometown.
