Jules Verne (1828.2.8-1905) was born in Nantes, a seaport in western France. My father is a very successful lawyer, and he hopes that his son will follow his father's footsteps. But Verne loved the sea since he was young and longed for voyage and exploration. When he was 11 years old, he volunteered to go on a boat as an intern and sailed to India, only to be found by his family and taken home. For this reason, Verne was severely beaten, and lying in bed with tears, he promised: "In the future, he will only lie in bed and travel in fantasy." Perhaps it is precisely because of this childhood experience that Verne objectively promoted his life to gallop in fantasy and created so many famous science fiction works. Jules Verne, the author of Twenty Thousand Miles Under the Sea, is not only the exaggeration, moving and scientific novels he wrote, but also the story he wrote in the book. Although it is not surprising today in the twenty-first century, in the age of Verne, people have not yet invented submarines that can travel underwater, Even the electric light hasn't appeared yet. Under such a background, Verne successfully created the Nautilus submarine in Twenty Thousand Miles Under the Sea. Twenty five years after the novel was published, the real submarine created by people is almost the same as that described in the novel. What kind of foresight is this? Therefore, the fantasy in Verne's works is based on science. Many of the science fantasies described in his works have been realized today. More importantly, the fantasy in his works is bold and novel, and it is interesting to read because of its lifelike, vivid and picturesque beauty. His works have thrilling plots, vivid characters and unexpected endings. All these make his works have eternal charm.

Finally, when the submersible reached the Norwegian coast, Arronas left without saying goodbye and announced the secret of the seabed he knew to the world.
