Gensheng looked at Yang Min awkwardly, scratched his head habitually, and said embarrassedly: "Sir, Sister Min, don't joke about me. I don't even know a few words, so how can I read a book!"

"Forehead......"

Yang Min, who was originally smiling, also seemed a little embarrassed and complained: "Sir, don't joke, okay? Gensheng is illiterate, what book do you want him to read!"

Gensheng continued: "Actually, I want to work in a craftsman camp. I am not bored, but because everyone is working, and my health is not bad, but I am really embarrassed to lie at home every day..."

Lin Xu smiled and said, "Gensheng, I know you can't recognize many words yet, but my book is specially prepared for you. There are not many words, basically all of them are patterns, so you can understand it!"

"All pictures of books?"

"Haha, just look at it..."

Lin Xu took out a thick booklet from his arms and handed it to Gensheng.

Gensheng took it, looked through a few pages, and his eyes immediately lit up: "This is... sir, have you made a new spinning wheel again?"

"What?! New spinning wheel?!"

Hearing this sentence, Yang Min was like an arrow from the string, jumping to Gensheng with a "rubbing" and then leaning over and taking a closer look, and said in surprise: "Sir, is this really a new spinning wheel?"

"Haha, that's right, this is a new spinning wheel I designed. If we use this spinning wheel to weave fabric, our weaving efficiency will be increased by at least 50%.

Lin Xu said with a smile.

"What!? Can it increase by another 50%?!"

Yang Min was so excited that she wanted to come forward and give Lin Xu a bear hug!

"Don't be so excited. This is just a sketch I designed. There is still a way to go before I actually manufacture it! Compared with the spinning wheels we use now, the production principles of this new spinning wheel are actually similar. The difficulty lies in the production of some parts and the requirements for the process are very high! It is difficult to manufacture by hand alone..."

"What should I do? If I don't rely on handicrafts, what else can I rely on?"

Yang Min asked in confusion.

"machine tool!"

Lin Xu spoke out two words in a deep voice.

"machine tool?"

Yang Min and Gensheng both looked puzzled on their faces. This is a new word they have never heard of!

"Roots, then turn back."

Lin Xu said with a smile.

Gensheng turned back a few pages, and he couldn't understand these strange patterns.

"Sir, is this the drawing of the machine tool?"

"Yes, this is the drawing of the machine tool!"

In fact, Lin Xu's idea of ​​making machine tools has a long history. Since he learned that nomadic tribes such as Tatars and the Huns have repeatedly invaded the Daning border, and the army of Daning, under the iron cavalry of these nomadic tribes, had the idea of ​​making machine tools!

Of course, manufacturing machine tools is not the ultimate goal.

He wanted to use machine tools to create a weapon specifically to restrain cavalry - firearms!

It has to be said that the wisdom of the ancients should not be underestimated. In many years of wars with nomadic peoples, they have summarized many methods to deal with cavalry, such as using obstacles, tripping ropes, trenches, traps, etc., and also using guerrilla tactics of infantry and straits to deal with cavalry.

Overall, these methods have certain effects, but the effects are average!

Especially when dealing with heavy cavalry, the effect is even more average!

In fact, only using firearms is the best way to restrain cavalry!

In the previous life where Lin Xu was located, it was not until the firearms were put into war on a large scale that the cavalry was completely suppressed!

Therefore, Lin Xu made up his mind from then on to build a firearm!
