a goof book

People can move up and down in space by machine, why not move up and down in time by machine? In order to solve this mystery, he spent two years making a time machine. But my friends didn't seem to believe it, saying it was just an ordinary machine, and I didn't dare to believe it until the machine disappeared with "I".He came to the future in a time machine, and went to the earth 800,000 years later because of an accident. At this time, human beings are divided into two categories: one is "cannibalism" living in the dark underground, and the other is "cannibalism" living in sunny land. When the time traveler learned that his time machine was taken away by cannibals, he found the machine after a long journey and launched a bloody battle with cannibals. Finally, the time traveler was black and blue all over. At this critical moment, he pulled down the joystick of the machine and left this place of trouble!
