When I opened the two Wan Li under the sea, I was curious. On the Nautilus under the sea and the protagonist in the book, naturalist Junasz started a legendary trip under the sea. We traveled all over the Pacific Ocean, Indian Ocean, Red Sea, Mediterranean Sea, Atlantic Ocean, Antarctic and Arctic Ocean, and met many rare underwater animals and plants, as well as underwater caves, back channels and sites. Let me know a lot about science, culture and geology, especially the refraction of light, the classification and collection of pearls, the structure of submarines ... these things have now become a reality. I lament the imagination of the author jules verne, who can predict the future world in a society where electric light has not been invented, and combine science with stories to create a magical underwater world.

Captain Nemo of Nautilus is a mysterious figure. He is gloomy but knowledgeable. He can repay tens of billions of national debts for France; Seeing my friend die, I will cry silently; Will give millions of gold to the poor; Will take in all those who hate the land; Will give a bag full of pearls to poor pearl pickers; Will escape from mankind and take terrible revenge ... Captain Nemo has a deep-rooted distrust of mankind, and his heart is full of endless pain, but he is also a kind person.

When the Antarctic is short of oxygen, there is only a trace of air in the piggy bank on the diving suit. At that time, they almost collapsed because of lack of air. At this time, Captain Nemo did not take his last breath to sustain his life, but left the chance of survival to the professor. He sacrificed his own life for the lives of others, and his behavior touched countless readers and me.

In the fascinating story, the author also warns people: while seeing that science and technology benefit mankind, we should also pay attention to preventing acts that are used and endanger human crisis. Jules verne put forward the idea of caring for seals, whales and other marine life and condemning overfishing ... In the face of the prophet's appeal as early as 200 years ago, I fell into deeper thinking: Does this book only make readers feel colorful adventures and gain vivid knowledge? No, it is enlightening us and making our minds get more from natural science.

Jules verne is telling us: Nothing is impossible, only the unexpected-only when you have a certain scientific background at that time can you have an imagination that comes from reality or is higher than reality, otherwise it is not science fiction but fantasy; Without imagination, purpose and direction, it is even more impossible to make scientific progress.
