Plot The book, a famous work by the French writer Verne, tells the story of Professor Aronnax and his servant, along with the harpooner Ned Land, who accidentally enter the submarine Nautilus while pursuing a \"sea monster\". In the ten months they had been on board, they had travelled 20,000 leagues, crossing the Pacific, Indian, Red, Mediterranean, Atlantic, Antarctic and Arctic, walking through undersea forests, volcanoes, plains, coral, watching pearl-fishing and mining, and seeing countless animals and natural wonders. Finally, Professor Aronnax, his servant, and the harpooner escaped when the Nautilus was caught in a great Arctic storm. Character What impressed me most in this book was that great navigator, Captain Nemo of the Nautilus. He loved the sea, the sea as his home, unremitingly explore the mysteries of the sea. He kept treasures from the sea and read books about it. He discovered and crossed the Arabian Tunnel, and finally reached the South Pole after paying a heavy price. His footprints covered the bottom of the sea, where he buried his companions and made the sea his final home. Sometimes, when he came ashore, he could see the waves gently brushing against the boat, and the sea level meeting the sky. He must have loved the sea even more. A man of extraordinary creativity, he served as captain, designer and builder of the Nautilus. He boldly used electricity to power his submarines; He not only set up library, museum, living room, bedroom and other functional rooms on the submarine, but also through clever design, \"Nautilus\" has extremely fast speed, hard shell, can not only dive deep into the sea, but also can swim in the ocean like a free fish. \"It\'s an exceptional ship,\" he said proudly. \"I love it like my life.\" He has a strong will. He ran out of air through ice to reach the South Pole; He fought bravely against the octopus to save his companions; He sailed around the world in search of the oceans. He always had a kind of undefeated confidence and perseverance to support himself to move forward. But Captain Nemo was also a cold, vengeful man. His family is dead, his country is dead, and his good life has been destroyed. He disguises his madness of revenge with indifference, he trains his crew, he rules his language, he builds his boat, all in order to disown the human race and better carry out his revenge. He regarded the sea as a graveyard as well as a home. It was only when he had sunk all the ships with the Nautilus and watched with indifference as terrified people struggled at the end of their lives that his vengeful heart was satisfied. I understand his hatred of humanity, but I don\'t think he needs to kill millions of innocent people to get what he wants. The painful past made him painful, but also tempered his strong willpower. With his love for the ocean, creativity and perseverance, he can do all kinds of exploration and research in the ocean alone, enjoy the fun of nature, and become a great and learned navigator, and live a carefree life. But because of his indifference and hatred, when he felt the beauty of the sea, the resentment in his heart became deeper and deeper. He\'s obsessed with revenge all the time, which ultimately drives him into a pit of evil that he can\'t get out of. When we encounter misfortune, only forget resentment, good at finding the good in life, learn to be grateful and tolerant, in order to get the real liberation of the heart. Review \"Twenty Thousand Leagues Under the Sea\" shows us the endless mysteries of the sea, but also tells the story of a great navigator buried in hatred. I, like the author, \"May the contemplation of so many wonders extinguish for ever the spirit of vengeance! May the judge disappear, and the philosopher continue the peaceful exploration of the sea! If his destiny be strange, it is also sublime.\"; May Captain Nemo shed his identity as an indifferent avenger, set his heart on the ocean, and become a great navigator without pain or hatred.
