Physics Teacher Travels Through Primitive Tribe

There are some flaws in the writing at the beginning that are acceptable, but it gets much better later on. Generally speaking, it is an okay original novel. I think it can be rated as 8 points. For encouragement, I will give it 5 stars. You can read it when you are short of books. It is short and can be read in three or two days. The last sentence is well written. How can there be so many time travels? It's just a dream.

Good logical thinking method, not a savage time travel, a civilized person

Interesting book

Well written, suitable for long-term follow-up

Well written and worth reading.

Real and simple, people help each other and everyone is united.

Except for time travel, it's very real and the writing is good. It made me see the kindness of people.

Write carefully, logically and not outrageously
