Inventing Things in the Great Tang During Zhenguan

Brother, this is not like a novel, it is like a popular science program. Apart from inventing science popularization tools, there is no plot, and the content of each chapter is like an instruction manual. Let's change the name: "Making and Improving Tools"

It's a good book. It's interesting and the content is compact and humorous. It was still 100,000 words, but now it's already over 100,000 with just over 80 chapters. You can't hold back a million words, or it won't be finished.
