Will people who have read Lu Ban's book really come back?

It will be all right. Lu Ban's book is divided into two volumes. The first volume is about craft, and the second volume is very dreamy. The first sentence of the second volume of Lu Ban Shu is that if you want to learn this book, you must first have five disadvantages and three shortcomings. Don't worry after reading the first book, if you haven't learned the second book, you should be fine.
