A few days later, the matter had been settled, and Li Feng immediately ran back to the craftsman village, but the seventh master stayed behind and was responsible for the supervision of the construction. Although, Li Feng is not afraid of the other party's slippery head, but it is always good to be able to prevent it from happening, otherwise, when the time comes, he really can't pay the house, and Li Feng can certainly not pay as promised. However, he is also difficult to account for those users who have paid money.

I thought that when I got home, I could rest for a while. However, what Li Feng didn't expect was that as soon as he came back, he was hurriedly pulled away by Rou Niang.

By the time the footsteps stopped, there was already a white scene in front of them.

"Cotton, hehe, I almost forgot about it."

Seeing the cotton in front of him, Li Feng remembered this matter. Nearly ten days have passed, and the cotton has already been dried and sent to the craftsman village.

"Yes, you see, these are all seeded after they have been removed, and they haven't been seeded over there. Didn't you say last time that this cotton still needs to be processed before it can be used? Indeed, this cotton is very soft and warm to the touch, and if it is made into a jacket or quilt, it will definitely be warmer."

The reason why Rou Niang was in such a hurry to bring Li Feng over was because she couldn't wait for Li Feng to come back to deal with the cotton. Rou Niang, who has been dealing with all kinds of clothes for many years, has never seen the finished product of cotton jackets and quilts, but she has long expected this effect.

If Li Feng hadn't said that these cotton still needed to be further processed, she would have planned to do it directly. It was hard to wait for Li Feng to come back, so he pulled him directly over.

"Are these seeded?"

Pointing to the pile of cotton in the corner of the room, Li Feng turned his head to look at Rou Niang with an incredible face and said.

"yes, isn't it wrong to remove seeds like this? Still is. There's not enough cotton. However, there is no way, the cotton seeds in these cotton are all wrapped firmly, and it took all of us several nights to clean them up."

Speaking of this matter of removing cotton seeds, Rou Niang also frowned, these in front of her. It's still the result of their family, busy for several nights.

"My God, I really admire you by peeling them off little by little, one by one. Never mind. It's also my fault for this matter, don't worry about it now, I'll go to Lao Tie Lao Tie first and ask him to help make something. ”

With his hands, peeling cotton seeds one by one, just thinking about it, Li Feng felt his scalp tingle. Thinking of Rou Niang, they actually made such a large amount of cotton like this. Li Feng suddenly felt distressed. But now is not the time to think about that, right now, the most important thing. It's about finding a way to deseed these cottons. Otherwise, just by peeling them one by one, it won't be finished until the Year of the Monkey.

"Make something? What are you doing? ”

For Li Feng's inexplicable words, Rou Niang was confused. looked at Li Feng and asked.

"Ginner, huh. It's something that's specifically designed to seed this cotton. ”

Of course, a ginning machine is used to remove cottonseeds, and when picking cotton, Li Feng has already thought of this problem. Actually, a simple ginning machine is not very complicated to make. In Lao Tie, Li Feng can make it out.

"Oh, really, let's go, I'll go see how this thing works. You don't know, lately, my hands are almost blistering in order to get this cotton. Let's go, let's go to Uncle Tie immediately. When the cotton is made and the quilts and jackets are made, they don't have to be frozen."

Seeing that Li Feng actually had a way to make something to remove cottonseeds, Rou Niang was a little impatient, and pulled Li Feng to walk out.

"Oh, why do you two have time to come to me today. Well, by the way, little madman, what about Uncle Seven, why didn't you see his old man come back with you? ”

The arrival of Li Feng and Rou Niang made Lao Tie feel surprised. Then he asked about the seventh master, at the beginning, the seventh master was in Chang'an City with Li Feng, but now, Li Feng is back, but the seventh master is nowhere to be seen.

"Seventh Master, he stayed in Chang'an City, and the construction site there needs him to be in charge."

"Okay, Uncle Tie, you don't have to grind here anymore. Brother Li, didn't you say that you want to ask Uncle Lao Tie for help. What the hell are you going to do, you should tell Uncle Tie how to do it. ”

Li Feng and the others were still trying to talk a few more words, but who knows, at this time, Rou Niang spoke, which made Li Feng and Lao Tie stunned for a while. You know, on weekdays, Rou Niang will not be in this situation. Maybe it's because it's more familiar, but from another aspect, it also shows that she's a little anxious.

"Well, little madman, what are you going to do again, let's hear it."

After Lao Tie was stunned for a while, he immediately became interested. He knew that as long as it was something that Li Feng made, it was definitely not an ordinary thing, and at least it could be regarded as strange.

"Hehe, actually, it's not a big deal, forget it, I can't understand it just by talking. Let's get started. Isn't it clear that everything is made clear?"

If you want to talk to the ancients about these things, it is difficult to explain them for three days and three nights. Everything is not as good as speaking with facts. When the thing is made, everything will be easy to say.

In fact, Li Feng said that the ginning machine to be made is only the simplest roller ginning machine, the most important thing is to use the surface of the roller with a large friction coefficient to adhere to and drive the cotton fiber, so as to achieve the effect of separating from the cottonseed. The structure is simple, easy to make, and simple to operate.

Especially with the skillful craftsman of Lao Tie, this is easier to make. The only thing that bothered Lao Tie was the connecting rod mechanism. This thing really made Lao Tie think a lot before he came up with it.

With the efforts of several people, two days later, a simplest ginning machine appeared in front of everyone. However, looking at the simple and rough ginning machine in front of him, Li Feng's mood became a little excited, and what was even more excited was Rou Niang, who immediately ordered Xiaohu to run home and get a bunch of cotton.

"Ah, it's done, it's really done, now it's okay, there's no need to pull cotton seeds one by one. This thing separates cotton from cotton seeds so quickly, and it's much better than picking it slowly by hand. Brother Li, let's take it home quickly. Then, get all those cotton seeds out, sit on the quilt, the cotton jacket"

Seeing the effect of this ginning machine, Rou Niang suddenly shouted again with uncharacteristically happy eyes. Then, pointing to the ginning machine in front of him, he wanted to get it home.

"Hey, that's a rarity. It seems that only things like clothes and fabrics will make Rou Niang so excited. ”

Looking at the elated Rou Niang, Li Feng suddenly felt a burst of emotion in his heart. However, for Rou Niang to take the ginning machine and remove the cotton seeds by hand, there is indeed a chill. Isn't this nonsense, otherwise, he Li Feng would still bother with this thought, what kind of ginning machine is he doing.

"Hehe, if she is allowed to see those large sawtooth ginning machines in modern society, she will not be happy to jump."

Although the ginning machine in front of me is definitely better than hand-picking cottonseeds, compared to those large machines in later generations, it is completely underground, a heaven, and there is no comparison at all. However, you must know that this is the Tang Dynasty more than 1,000 years ago, not the modern society with the development of science and technology after a thousand years.

"Don't worry, Rou Niang, don't worry, this is a good thing. It's really a good thing, although I don't dare to say that there is no one who will come after, but it is definitely a great discovery that has never been seen before. It's absolutely right, a priceless baby."

Li Feng was about to speak, but who knows, there was a person who moved faster than Li Feng and stopped Rou Niang first, and this person turned out to be Lao Tie. Moreover, while talking, his eyes were staring at the ginning machine in front of him motionlessly, as if the thing in front of him was not a ginning machine, but a big beauty.

"Hey, it's really not to underestimate the ancients. I didn't expect this old iron to be so shrewd and find out so quickly that this ginning machine is the most precious place, it's really not easy."

Lao Tie, who was so excited, first made Li Feng feel strange, it stands to reason that Lao Tie would not have such a look. This ginning machine is really not a difficult job for Lao Tie, and there shouldn't be much sense of accomplishment. However, soon, Li Feng found out what the problem was.

Although, Lao Tie stared at the ginning machine with motionless eyes, but he only stared at the lower part of the ginning machine, and for the upper part, he didn't even look at it. Following Lao Tie's gaze, Li Feng suddenly saw the foot pedal. And Li Feng also understood all of a sudden, what was it that made Lao Tie so excited.

What Lao Tie was really excited about was the connecting rod mechanism. This is specially designed by Li Feng, in order to directly press the pedal up and down with his feet, so as to drive the leather roller, so as not to shake it with his hands, which is not so tiring.

The so-called connecting rod mechanism, in fact, is very simple, and the most important role is only one. That is, the rectilinear reciprocating motion and the rotary motion are converted. This is a kind of principle design that has not yet been discovered in this era.

"Hehe, in my opinion, the greatest design of this ginning machine is here."

Sure enough, immediately, Lao Tie pointed to the part of the pedal and said to everyone with a smile on his face.

"Uncle Tie, what's here, isn't it just a pedal?"

Li Feng understood what Lao Tie meant, but the rest of the people didn't understand. Especially Rou Niang, at this moment, she asked with curiosity on her face.

"Then you have to watch carefully"

For everyone's doubts, Lao Tie did not explain anything with his mouth, but began to rotate the leather roller vigorously, and as the leather roller rotated, the foot pedal really moved up and down.
