In the early morning, shortly after dawn, there was still a little firelight in the carpenter's room. Han Cheng squatted here, one hand on his knee, and the other hand holding the wooden handle on the big wheel of the spinning machine, shaking it with his hand.

As the big wheel turns, the small wheel next to the big wheel is also driven by the big wheel to turn.

At the center of the small wheel, there is a wooden stick about the length and thickness of a chopstick.

There is a curved groove carved on the top edge of the wooden stick.

The groove is not wide, but relatively deep, and is used to hold the fibers during spinning.

The small wheel was spinning very fast. Even when Han Cheng was turning the big wheel, he did not deliberately increase the speed, and the small wheel was still spinning very fast.

So much so that even the groove on the top of the stick above the small wheel cannot be seen!

Han Cheng was turning these around and looking at the scene in front of him. Although he hadn't slept for most of the night, he was not tired at all. He looked extremely energetic, with an unconcealable smile on his face.

Even though he hasn't asked his young wife Bai Xuemei to come over and carry out the experiment yet, Han Cheng can be sure that this matter is basically done!

I have figured out the most critical part of this hand-cranked spinning machine that I made by myself!

I really have to thank myself for the dream I had last night.

If it weren't for that dream that gave me inspiration and enlightenment, I would still be at a loss as to how to solve this problem.

I can’t think of a way to use the big wheel to drive the small wheel and ultimately solve this problem!

"Brother Cheng, is this thing done?!"

Sister Bai Xue walked to a place not far behind Han Cheng, and stood there quietly for a while, watching the small wheel that was spinning rapidly as Han Cheng was shaking it. Finally, she couldn't hold back the surprise in her heart, and spoke excitedly.

Han Cheng, who was concentrating on feeling the spinning machine after a rest, was frightened by the sudden sound of business. He stopped what he was doing and turned back suddenly. When he saw Bai Xuemei who was full of excitement, the fear in his heart disappeared a lot at once.

Bai Xuemei didn't expect that her actions just now would scare Han Cheng.

Seeing Han Cheng's big reaction, he couldn't help but stick out his tongue.

"Come, come and try this improved thing."

Han Cheng regained his composure and greeted Bai Xuemei who was sticking out her tongue with a smile.

Sister Bai Xue came running over.

She looks so lively, just like a child who has not fully grown up. She doesn't look like a mother of three children at all.

"Still hold this thing and shake it. This is where the fibers are hung."

Han Cheng introduced Bai Xuemei to her like this, then stood up and gave his seat to Bai Xuemei.

After Bai Xuemei replaced Han Cheng's position, she first held the wooden handle with her hand and shook it a few times. After feeling it for a while, she stopped and tied the fibers to the wooden pillar of the small wheel.

Then he pulled the fibers with his left hand and held the wooden handle with his right hand and started shaking it.

After some modifications made by Han Cheng, the wooden pillar installed on the small wheel is now on the same side as the wooden handle installed on the large wheel.

This makes the operation very smooth. There is no need to stretch out your arms awkwardly and lean your body back as before, for fear of being hit by the wheels on the simple spinning machine.

As Sister Bai Xue turned the wheel with her hands, the big wheel slowly turned and caused the small wheel to turn rapidly.

The few fibers that were originally loose quickly gathered strength and became one!

Sister Bai Xue only turned the big wheel three or four times, and the fiber from her hand to the small wheel, which was about half a meter long, was already stretched!

Sister Bai Xue stirred the big wheel with her right hand continuously, then turned it, and tilted her left hand, which was holding the fiber, to the side, changing the fiber from being parallel to the small wooden stick to a vertical state.

After performing this action, the yarn that had just been tightened was naturally wrapped around the small wooden pillar.

Seeing this, Sister Bai Xue stopped shaking her right hand, and the rotating small wheel also stopped.

She habitually wanted to use her left hand to wrap the fiber in her left hand and fix it on the top of the small wooden pillar.

But when he saw the thin, curved groove in this place, and remembered the use of this groove mentioned by Brother Cheng, he resisted this habitual action and instead stuck it in the small groove.

After it was locked in place, he began to hold the wooden handle on the big wheel of the spinning machine with his right hand and started to shake it.

And her left hand also moved backwards.

It pinched the fibers and once again distanced itself from the small wooden pillar of the spinning machine.

After just three or four turns, the fiber, which was more than half a meter long, once again became yarn.

Sister Bai Xue stopped what she was doing, and gently lifted up her left hand that was holding the fiber, and took out the yarn stuck in the groove.

Unlike the previous one, which requires using fingers to clip it from the top of the small wooden stick, it is very convenient.

Then her left arm, which was originally pointing backwards, also moved toward the front left, and this time the yarn and the small wooden stick were in a vertical relationship.

With the stirring of the right hand, it was instantly wrapped around the small wooden pillar of the small wheel.

This speed is much faster than the previous time when using a string gyroscope!

After all, when you use a spinning top to wind the spun line around the handle of the spinning top, you need to pull the line with one hand and hold the spinning top with the other hand, winding it around in circles...

Han Cheng stood here quietly watching Bai Xuemei spinning the yarn on the spinning machine that she had modified after most of the night's hard work. Seeing how easy it was to use, his mood also became particularly good.

At the same time, there was some expectation in my heart, which came from the shock that my wife, who had never seen the world before, would experience the usefulness of the new tools after using them.

This is bound to happen.

Han Cheng, who knows his wife very well, is particularly sure about this.

However, today seems to be a little different.

Han Cheng stood here waiting for a long time, but his young wife Bai Xuemei did not move. She was just spinning the thread with great interest and was extremely devoted, as if she had forgotten everything else.

Han Cheng stood here and waited for a while. Seeing that Bai Xue had wrapped a lot of yarn around the small wooden pillar and had no intention of stopping, and seemed to be completely immersed in this matter, he finally couldn't wait any longer and had to speak up himself to interrupt his wife who had fallen into an infinite loop and rescue her.

"How is it? Is it useful?"

Han Cheng asked Bai Xuemei with a smile.

When Bai Xue heard Han Cheng's words, she realized that she was trying out the machine and Brother Cheng was standing next to her.

"It works! It works! It's really so useful!"

Sister Bai Xue said hurriedly, as happy as a child weighing over 100 pounds.

She had never thought that spinning could be so fast!

Han Cheng couldn't help but smile when he saw this: "If it works, then don't forget what you promised me before, and remember to fulfill your promise!"

I don't know what conditions this shameless guy Han Cheng put forward to Xue Mei and what kind of agreement he made before. As a person of this era, and having been an old couple with Han Cheng for a long time, in such an excited state, she couldn't help but blush when she heard Han Cheng say such words.

Despite this, she still nodded vigorously without much hesitation.

As a person of this era, although I have been influenced by Han Cheng over the years, I am quite different from many people of this era.

But when it really came to these things, she had never been afraid.

After all, these things, although a bit weird, can still bring people happiness.

Fresh gameplay can bring some fresh experiences and...happiness!

Han Dashenzi, who was always serious, couldn't help but smile when he saw this scene. It seemed that he was happier than having worked so hard and with some luck, he finally made a useful spinning machine.

Men, their minds are so strange most of the time. There are obviously many important things that can bring people joy and a sense of accomplishment, but most of the time, they can't help but be attracted by certain things, and successfully go astray, and can feel deep happiness because of it.

"Brother Cheng, how did you do this? Why is it so useful? How does this little wheel turn so fast?"

Sister Bai Xue resisted the urge to squat down again and continue spinning. She turned to look at Han Cheng and asked.

It was unknown what scene the extremely serious Son of God was thinking of, but when he heard what Sister Bai Xue said, he withdrew his thoughts from some extremely beautiful scenes he had imagined. He held up the waistband of his pants with one hand and reached inside with the other hand to move the position of a guy who was more excited than him and made adjustments.

During this process, Han Dashenzi's face did not turn red, and his heart did not beat. He even answered Bai Xuemei's words seriously while doing these things: "This is because the big wheel is bigger, and the small wheel is smaller..."

These words suddenly sounded nonsensical, like incomprehensible nonsense.

But this is indeed the key to Han Cheng's improvement of the spinning machine.

The small wheel itself cannot rotate, and needs the big wheel to make it rotate.

This small wheel is indeed very small, with a diameter of only three centimeters, while the diameter of this large wheel is one meter!

In other words, the circumference of the large wheel is a little more than thirty-three times the circumference of the small wheel.

It is like a person holding the wooden handle on the big wheel and turning it one circle, and the small wheel connected to the big wheel and turned by the big wheel will turn more than thirty-three circles!

In this case, how could the little wheel not turn fast?

Han Cheng organized his words and explained it to Bai Xuemei like this.

After a while, Bai Xue's sister looked at Han Cheng and stars appeared in her eyes again.

Brother Cheng is really smart!

It’s true wisdom!

Such complex and useful things can be manufactured!

A certain Son of God accepted the admiration from his own wife very calmly. He was not embarrassed at all and even enjoyed it a little.

"It's not that difficult..."

Han Dashenzi said this to Bai Xuemei and waved his hand, as if this thing was very simple to make and it didn't take him any effort. He just made it with a casual move.

Looking at Brother Cheng in this state, Sister Bai Xue's mind couldn't help but emerge the time when Brother Cheng couldn't sleep for half the night because he was thinking about the spinning machine, and had to ask her to feed him sleeping pills.

Could it be that those were all my illusions?

Sister Bai Xue seemed stunned for a moment, and she couldn't figure it out...

The carpenter's room was crowded with people. The core members of the Qingque tribe, including Wu, the eldest brother, Shitou, Yuan, Tietou, and Heiwa, all gathered here at this time.

Even technical experts like Bo, who were busy in the shipyard downstream of the tribe, were rushed back from there.

Sister Bai Xue sat on a shorter chair with a backrest, pulling the fibers from the hemp with her left hand, and with her other hand holding the wooden handle on the large wheel and spinning in circles.

There were also a few women from the tribe nearby who always had spinning tops in their hands, spinning the thread with them.

This is not a competition, but an attempt to compare the old and new spinning tools to see the specific effect of the new spinning tool and get more specific data.

These women who are using spinning tops to spin the thread are doing it as quickly as they can.

After this period of time, their faces were already covered with sweat, and due to fatigue, their speed inevitably decreased.

On the other hand, Bai Xue, who was sitting on a small chair and spinning yarn with a newly made hand-cranked spinning machine, was still relaxed, without a trace of sweat on her face.

The speed didn't slow down either.

In fact, during this process, she became more and more familiar with the operation of this hand-cranked spinning machine, and her speed gradually increased.

After a while, Han Cheng looked at the people who were spinning with spinning tops and whose speed was getting slower and slower, and then looked at Bai Xuemei who didn't seem to feel any fatigue, so he shouted to stop.

Then, with the help of everyone, they began to stretch out the yarns spun by several people during this period one by one for comparison.

After comparison, it was found that under the same conditions, Bai Xuemei could spin the thread using a spinning machine two or three meters longer than the three women spinning with spinning tops combined!

And now, the hand-cranked spinning machine has just appeared in the tribe. Sister Bai Xue is not particularly skilled in its operation, and this newly made spinning machine still has a lot of room for improvement.

The spinning top has already appeared in the tribe, and everyone has mastered it!

The gap between the two is very obvious at a glance!
