Time and Space

If time is a rushing river, then it cannot flow back anyway. Maybe people can build a boat to go upstream? However, since time is a river at this time, then people can no longer be understood as people, but as water belonging to time, follow it away... But since it is a river, it has tributaries. If someone outside of time makes a jump in space... "Time and Space" is a youth fantasy novel. I hope readers will like it! !
