About time travel

At the beginning of the story, I thought that the earth before me was a quiet paradise, where people wore fine clothes and did not work, but still had food to eat. Isn't that the utopia we've always dreamed of? But it is through the description of the time traveler's search for a time machine that the cruel world is truly unveiled. By this time, humans had evolved into two extreme, opposing creatures, the smiley Eloi and the lemur-like Morlocks. The Eloi depend on the Morlocks to create the material conditions necessary for their life, on the one hand, the Morlocks eat the Eloi for a living. Reading this, it really makes the scalp tingle. Later, the protagonist escapes from here and travels millions of years to see what the future Earth will look like. These three places impressed me the most after reading.
