The content of this book is so interesting! It mentioned many mysterious relics of prehistoric civilization, such as the Colossus of Easter Island and the mystery of the construction of the pyramids, which opened my eyes. The author's writing style is concise and clear, and he tells about the complex prehistoric civilization in easy-to-understand language, which is very suitable for new mothers like me to read. I especially like the discussion about extraterrestrial civilization, which feels like it opens the door to a new world. All in all, this is a great book worth reading!

It's quite interesting. I wonder why there are no novels about traveling through the Qin Dynasty to solve these unsolved mysteries.

Very beautiful, the story is also very exciting and vivid

A nice book
