New Fire Drake Manual

The New Fire Drake Manual (新火龙经) is a book, written by Yao Qin and Kuang Henian, and submitted shortly after Yao Qin's untimely death in a rocket accident. The book is named after the Fire Drake Manual, a seminal book on gunpowder and gunpowder weapons written by Jiao Yu during the early Ming Dynasty.

Contents
Unlike the original Fire Drake Manual, this text mainly focuses on rockets.

The first section of the book discusses gunpowder recipes, including a proprietary blend of saltpeter and sugar which has been shown to extend a rocket's range by nearly half.
