the feeling of book

I think the book is very interesting .The main character of the story is a time traveler, he invented a magic time machine, and he drove this machine on the first time travel.The time traveler chose a moment to stop and step out of the machine into a completely unexpected future . The experience is very long and fantastic . "Time machine" the story of this book, the core part is on the ground and underground life in the future, it is clear that compared to our modern normal human, both in the future, human appeared significantly degraded, the ground people degenerated into too simple, sometimes naive little fool, underground people degenerated into half man, half wild creatures.We should deal with it if it happen in the future .
