It turns out that the saying that you can't become a fat person by eating one bite is very true.

Except, of course, the kind of worm that swallows prey thicker than one's own body, causes one's body to grow larger and bloated at a speed visible to the naked eye, and directly becomes a big fat man.

Han Cheng now deeply understands the wisdom brought by this common saying,

When he first tried to build a spinning machine, he wanted to spin as many threads as possible at a time to greatly improve his work efficiency.

But after some experiments, it was found that under the current technical conditions, this simply does not work.

In the end, all the extra wooden pillars were removed, leaving only the middle one.

Looking at the simple spinning machine that had already spun a lot of yarn under Bai Xuemei's operation, Han Cheng's face couldn't help but show a smile.

At present, it seems that I have figured out a lot of things and found the basic principles.

On the basis of the current simple spinning machine, in view of the problems, constantly solved, adjusted, Han Cheng believes that he will be able to get a good spinning machine.

When you're in a good mood, you're in a good appetite.

Han Cheng ate two and a half bowls of vegetable soup and dried millet rice before he stopped eating.

"Let's go, let's stop studying it, go back and get a good night's sleep, and then do it again when we get up."

Han Cheng ate the last bite of food, looked at Bai Xuemei, who was still sitting on the pier, shaking the simple spinning machine with her hand and constantly experiencing this novelty, and said out loud.

Han Cheng opened his mouth, and the child daughter-in-law, who had always been well-behaved, immediately stopped her hand, stood up, and walked out of the courtyard of the carpenter's room with Han Cheng, who was holding an empty bowl and chopsticks, and walked towards the house where the two lived.

When people let go of their minds, the quality of sleep will improve.

Originally, Han Cheng wanted to take a short nap and get up, and then start to study and make changes on the spinning machine that had achieved a small success, but when he woke up, he found that the sun was already in the west......

Rubbing his eyes, sitting here stunned for a while, Han Cheng shook his head and stood up and walked outside.

When he woke up like this, he felt refreshed, and his whole body was extremely comfortable.

Bai Xuemei was in the shade of a tree not far away, using a line top to close the rope one by one.

There was a small cradle next to it, and in the cradle lay a little baby.

The little baby opened his round eyes and sucked on one of his fingers, relishing and drooling, as if he had eaten a supreme delicacy.

Seeing Han Cheng come out, Bai Xuemei's movements in her hands did not stop, and she smiled at Han Cheng.

Han Cheng, who watched such a scene and such a scene, couldn't help but smile.

The heart is extraordinarily warm, and the beauty of the world is probably like that......

Han Cheng didn't ask Bai Xuemei why she didn't shout such nonsense as getting up, she walked over to look at the little son in the cradle, grimaced at him for a while, and then reached out to touch Bai Xuemei's head, then bent down and reached out to pick up the little son, and with the other hand, he carried the movable cradle and walked towards the carpenter's room.

Without Han Cheng opening her mouth, Bai Xuemei consciously followed Han Cheng towards the carpenter's room.

This has become a habit that the two of them have developed in the past few days.

When he came to the small courtyard of the carpenter's room, where Han Cheng made a spinning machine, Han Cheng put the cradle that he had half carried and half pulled in the most shady place, put his youngest son inside, and let him continue to play.

Bai Xuemei came over with a chair, placed it on the edge of the cradle, and continued to spin here with a light and casual spinning top.

As for Han Cheng, here he began to think about how to transform this simple spinning machine.

The spinning machine of this test product is indeed usable, but it is not convenient and the efficiency is not high.

After Bai Xuemei's previous experiment, it was found that at the same time, spinning with such a spinning machine was not even as fast as Bai Xuemei's own spinning top.

When such a situation happens, you don't have to think much about it to know that this thing that Han Cheng made is relatively wasteful.

Han Cheng is currently here thinking about how to transform it.

If you want to increase the speed of spinning, you need to make these fibers work faster.

In other words, the speed of the simple spinning machine needs to be accelerated.

Han Cheng sat here and thought for a while, then reached out and grabbed the handle of this simple spinning machine, and quickly turned it.

It was extremely fast, and it all made some whining sounds.

Things that come and go quickly are probably going away faster.

Han Cheng didn't have long to maintain this speed, and his speed gradually slowed down, and finally stopped.

Under Bai Xuemei's somewhat surprised gaze, Han Cheng shook his head while shaking his somewhat tired arm.

Relying on this method of quickly turning in circles to speed up the textile speed is not possible, it is too tiring, and it is even more tiring than using a line spinning top.

Spinning is something that takes a long time to do.

Now in such a short period of time, people feel tired, then this is obviously not possible, there are still many things that need to be improved.

But how can this be improved?

How to solve this headache?

Han Cheng sat down and thought about the humble spinning machine.

He had a vague feeling that as long as he solved this problem, the spinning machine would basically be able to make it out of himself.

But how can this problem be solved?

Han Cheng fell into deep thought.

This kind of thinking lasted for about half a day.

Until Bai Xuemei, who was sitting on the side spinning with a thread top, thought that Brother Cheng was asleep, Han Cheng, who had been holding his head with his hands and maintaining a motionless posture, finally stood up.

He got up and walked to the side.

After picking up the materials in the carpenter's room, I walked over with some materials in my arms.

These are bamboo, wood, and extremely strong vines that can be used as ropes.

Han Cheng put these things down, thought about them, turned around and returned to the carpenter's room, and after a while, he came out.

One more thing in hand.

It is a chisel made of bronze.

Han Cheng put the chisel down and began to dismantle the improvised spinning machine.

The main thing is to separate the rotating body from the shelf that supports it underneath and allows it to rotate.

After separating, Han Cheng placed it flat on the ground, and in the middle of this wooden column, a total of six points were evenly chiseled around the column.

Then he took the chisel and axe and began to drill holes at these points, one after the other.

After a while, six eyes of similar size and depth were beaten one after another.

Han Chengcheng found suitable wood from the bamboo and wood materials he bought, cut it off, and cut it into six sticks of length.

After repairing one end of each of them, one of them was nailed into the six holes in the wooden pillar, and it was firmly secured.

Then Han Cheng used a relatively long vine to wrap around the top of the six bamboos one by one, and finally fixed them together end to end.

In this case, a circle is completed.

If you ignore the material and the large and somewhat excessive axle, you will find that this thing made by Han Cheng is very similar to the bicycle wheels of later generations.

After carefully inspecting it and confirming that it was sturdy and there was nothing wrong with it, Han Cheng began to install it on the wooden shelf.

After a while, Han Cheng stopped and began to raise the shelf.

If the shelf is not heightened, the wheel, which has a much larger diameter, will hit the ground and will not be able to rotate at all.

After a lot of busyness, this wheel-like thing was erected by Han Cheng on the heightened shelf, and the installation was fixed.

On one side of the large wheel, there is a handle that can be held in the hand that can be shaken, and on the other side of the wheel, there is a slender wooden post on the outermost circle of the wheel for hanging threads.

Han Cheng shook the wooden handle a few times with his hand, and it was quite light.

"Come over and see how it is now, if it's better."

Han Cheng said to Bai Xuemei who was not far away.

Hearing Han Cheng's greeting, Bai Xuemei, who had been interested in the situation here, immediately put down the thread gyroscope in her hand, walked to Han Cheng's side, and skillfully tied the fiber to the small wooden pillar specially used to tie the fiber on the modified spinning machine.

Then he squatted on the edge of the spinning machine, holding the fiber in one hand and the handle of the spinning machine in the other hand and began to shake it, trying to weave with the newly modified spinning machine.

But just at the beginning, some problems have already been discovered.

For example, the handle on the spinning machine and the wooden post on the spinning machine are located on either side of the big wheel.

If you want to work with this spinning machine, you need to have two hands on either side of the spinning machine.

In other words, man is in a vertical relationship with the wheel that spins on the spinning machine.

At the beginning, when the spinning machine did not have this big wheel, there was no problem in this way, and it was possible to spin in such a posture, and it would not feel so uncomfortable and awkward.

But now it's not done, now the wheels have become a lot bigger, and people's arm spans are limited, in this case, in order to ensure that their bodies will not rub against the wheels, so that the wheels can rotate normally, Bai Xuemei's hand with the fiber, can not extend too much outside.

Not being able to move too far means that the distance between the hand and the wheel is short, and it is impossible to spin too much yarn at once.

Moreover, the reason why Han Cheng made such a big wheel come out was to wonder if the wheel of the spinning machine would become faster if it became larger.

Now it seems that this is impossible.

Bai Xuemei shook it with her hand holding the wooden handle, and when she held the wooden handle and shook it around, the big wheel would rotate with it.

It is not because the diameter of the wheel increases that the speed of the wheel increases.

Standing here watching Bai Xuemei spin the yarn for a while, Han Chengcheng shouted to stop.

As it stands, there is no need to continue experimenting.

Because the problem is already very big now!

Bai Xuemei obediently stopped, and then returned to the edge of the cradle.

At this time, Xiao Huangdou, who was playing and didn't know when he fell asleep, had woken up at this time, and there was a tendency to make trouble.

Bai Xuemei, who is a mother, obviously has extremely sufficient experience in this.

She bent down to pick it up and began to feed the baby.

The little pea who wanted to make trouble just now calmed down instantly.

Han Cheng sat here, and after watching his daughter-in-law feeding the child for a while, he once again shifted his gaze to the spinning machine in front of him, which was still not good, and fell into deep thought, only to feel that his hair was about to fall out......

The weather was hot, and the sun shone on the ground as if it was on fire.

On the threshing field, the roaring four-wheeled tractor is connected to the lifting machine through a belt, which rotates the thing quickly and whirring.

A strong wind came out of it, blowing the bran far away, leaving only clean wheat......

Han Cheng woke up from his sleep and opened his eyes to see a piece of moonlight falling through the gourd shed.

Han Cheng lay there without moving, experiencing the silence of the moonlit night and the beauty of the dream just now.

Recalling the dream just now, his thoughts were suddenly pulled back, and suddenly he was not in a primitive society now, but back to the years and years that he couldn't go back......

With a warm and somewhat melancholy state of mind, of course, it disappeared with the appearance of the rotating wheel on the front of the four-wheeled vehicle and the rotating hoist.

Han Cheng, who was lying there quietly, sat up suddenly, the moonlight shining on his face, and there seemed to be a light flashing in his eyes.

He sat here, his eyes sparkling.

After a while, he got up in his cloak and, by the light of the moon, made his way to the carpenter's room......

A place in the carpenter's room was lit up, flickering slowly in the night breeze.

Han Cheng sat here, busy here with tools in his hands.

Sometimes he would be busy for a long time, and sometimes he would stop his movements and think for a while......

Time passed quietly, and before I knew it, the sky was already bright.

Bai Xuemei woke up, turned her head to look, but didn't see Han Cheng's figure.

The bed that Han Cheng slept on was only a small pea.

Brother Cheng didn't know when he woke up and got up.

As if she had a heart, Bai Xuemei, who stood here stunned for a while, walked towards the carpenter's room.

In the small courtyard of the carpenter's room, Han Cheng was holding the wooden handle in his hand and turning the simple spinning machine, making some noises.

At this time, the spinning machine had changed a lot.

The style of the large wheels has not changed, and a rest has been given to make it more neat.

On the side of the large wheel, which is almost one meter in diameter, there is also a small wheel connected to it......
