Chapter 657 The Physical Book of "Material Empire" Has Been Published

The first volume of the physical book of "Material Empire" has been published, and the subsequent volumes are being edited intensely, and are expected to be published in the next few months. I have already got the sample book, the printing quality is very good, and the light paper is used, which feels very light and tall.

It is currently available at various online bookstores. The single volume is priced at 40, and the lowest discounted price I have seen seems to be around 26, please support.
