The rise of nanometers

Thank you all for your continued support. I originally planned to finish it at the end of August, but due to strong requests from book friends, I decided to write it for one more month.

During this period of time, I encountered a lot of troubles. I was out of shape and had problems at work, family, relationship and body. These things consumed too much of my energy.

I can only apologize to everyone, but I have finished writing about the solar system.

The new book will be released on October 9th. I hope everyone will support it then! (ω｀)
