Wu walked forward, circling around the spinning machine that had just proved its worth, appearing to be particularly amazed.

During this process, he would occasionally reach out his hand to touch the spinning machine, then stir it a few times by holding the wooden handle.

His wrinkled face was full of smiles, just like a child who had obtained a new toy. His whole body was filled with curiosity, excitement and joy.

Of course he was happy. After all, he had just witnessed with his own eyes how good the spinning effect of this thing called a spinning machine by the Son of God was!

If the Son of God had not called for a stop and allowed these people to continue, those using the spinning tops would have been slower and slower without a break.

On the other hand, Snow White, who was spinning on a spinning machine, did not show any such tendency.

Wu knew clearly that if things continued like this, the gap between the line spun by a spinning top and the line spun by a spinning machine would become even bigger!

In other words, with the help of the spinning machine, the work that originally required four people can now be completed by one person!

This means that three quarters of the manpower has been saved!

This is three-quarters of the manpower!

Thinking about the large number of people in his tribe who are working hard to spin yarn, and then thinking about the manpower that will be saved, how could the witch not be happy?

In fact, it wasn't just Wu. Everyone else present was also extremely happy.

Because this thing is so useful and has a huge impact on the tribe.

Lame, the first carpenter in the tribe, stood here staring at the spinning machine without blinking, or to be more precise, at the two wheels of different sizes with evenly spaced bumps and depressions.

Looking at the small wheel that was connected by these protrusions and depressions and was driven to rotate continuously, Lame's eyes sparkled, and it seemed that something emerged in his mind.

This was a completely new idea and a completely new direction, which brought him a lot of inspiration and enlightenment.

These inspirations and enlightenments have not yet been specified in any specific place or on any specific thing, but I am sure that they will be very useful in the future and will enable me to make a huge breakthrough in the things I create!

Looking at the reactions of the people in the tribe, Han Cheng, who made such a thing by himself, felt particularly comfortable.

This kind of satisfaction and sense of accomplishment is something I have never experienced before, when I provided some ideas to Bo and others and helped them to come up with things!

No wonder the Carpenter Emperor was so obsessed with woodworking, it turns out that if this thing is made well, it can have such an effect!

After everyone's busy work, more than half of the morning time had passed.

Han Cheng, who had not slept for most of the night, finally felt sleepy.

He returned to the house where he lived, lay down on the bamboo mat, and soon fell asleep.

He fell asleep, but the excitement caused by the appearance of the spinning machine in the tribe did not diminish.

More and more people knew that the Son of God had made a very, very useful new machine, and many people went to the carpenter's room to visit and broaden their horizons.

After seeing the performance of this new machine and knowing its significance to the tribe, everyone was extremely happy and excited.

Of course, there is also deep admiration for the Son of God!

Especially the women in the tribe.

This machine is simply used to rescue them!

In the past, they didn’t think it was hard to use a spinning top to spin thread whenever they had nothing to do.

But now think about many of them, after they no longer have to use spinning tops to spin thread whenever they have nothing to do, many of them suddenly feel a deep sense of happiness.

This is a kind of relaxation that radiates from deep within!

…

There are still many places in the spinning machine that need to be modified.

For example, the axis of a spinning machine.

If the shaft is well made, the wheel can rotate faster and more lightly, which makes people feel more relaxed and the weaving efficiency is also high.

Another example is the wheels...

Han Cheng would make these things when he wanted to, and when he didn't want to, he would ask professional carpenters in the tribe to do them.

After all, he is not a professional carpenter and he still has a poor grasp of some delicate work.

But these things are trivial.

Since he had already invented the hand-cranked spinning machine, there was no longer anything that required thinking.

The people in the tribe made improvements on it by making each component more sophisticated and suitable based on the existing foundation.

It's not difficult to follow the example of others.

At least it is not difficult for the carpenters in the tribe who have already mastered the craft.

Under such circumstances, the improved hardcover version of the hand-cranked spinning machine soon appeared in the tribe, and its number was increasing.

In some places in the tribe, one can already see the women sitting there, turning the spinning machines with their hands and spinning non-stop.

Because this thing has just come out and is still a novelty in the tribe, it is very popular now.

Several people competed for the use of one spinning machine, or they agreed on who would use the spinning machine to spin the thread for a period of time, and then the others would take over.

Han Cheng couldn't help but smile when he saw this scene.

These people are just curious for a while. After a while, when the hand-cranked spinning machines become popular in the tribe, many people in the tribe will no longer have the same interest as now...

Lame, who has been staying in the downstream shipyards for some time, has become a little "unemployed".

He is now obsessed with gears.

Therefore, a lot of gears were made.

Some are made purely of wood blocks, while others are made of a mixture of bamboo and wood.

Some use vines, sticks, etc.

Of course, Bo was not the only one who discovered the usefulness of gears because of the spinning machine and became increasingly obsessed with them. The person responsible for making the mold also made a bronze mold.

And bronze gears were cast out of bronze.

During this process, everyone also began to study in depth what specifications of gears are most comfortable to use and have the best performance.

What is the appropriate density of gear teeth?

I don’t know since when the weather has not been that hot.

Han Cheng thought about it and felt that this change should have started from the autumn rain a few days ago.

Every autumn rain brings a chill.

The sky also became high and distant, with scattered white clouds floating in it.

From time to time, flocks of birds fly across the sky. When the flocks are large, they really have the momentum and sight of covering the sky and the sun.

So much so that the geese in the tribe's increasingly larger goose pen couldn't help but flap their wings along with them, wanting to fly south with them.

But this is obviously impossible to happen.

This is not only because the considerate people of the Greenbird tribe often come with scissors to trim their feathers one by one and cut off the excess hair on their wings, but also because the goose house where they live is always covered with a net woven with ropes.

These two layers of things are constantly reminding them that they do not want to fly south, but just want to stay quietly in the Qingque tribe, laying eggs for the people of the Qingque tribe to eat.

The white clouds in the sky spread into the river of the Qingque tribe, in clusters.

In addition to the reflections above the sky, there are some real things.

If you look closely, you will find that these things are nothing but open white sails.

A ship with white sails is sailing on the water, and it is also making some turning movements.

If someone from another tribe who knows a lot about ships came here at this time, he would be stunned by what he sees.

Because this large ship with white sails did not use bamboo poles or oars to turn.

Just a person standing on the stern pushed a wooden stick as thick as a baby's arm to one side, and the boat turned!

Such a scene would surely shock them greatly!

Han Cheng was not from another tribe, so he would not be shocked by the scene before him.

But looking at the scene in front of him, he couldn't help but smile.

The sailboat in front of me is still the same sailboat as before, but there have been great changes compared to before.

Just like a rudder used to steer a ship.

Today's ship rudder has become a real ship rudder, which is fundamentally different from an oar.

It only has the function of steering left, and the function of relying on swaying left and right to provide the ship with forward propulsion has been completely cancelled.

If one function is sacrificed and only one function is left, the effect will naturally be better than having both functions.

As the function changes, the style will also change.

The unsuccessful previous rudder relied on a solid wooden pillar, fixed diagonally to the stern.

Today's ship's rudder is fixed straight up and down at the stern.

In order to allow the person holding the rudder to better control the rudder for steering, a wooden stick about half a meter long is installed horizontally on the rudder pole.

When turning is necessary, people can hold the wooden stick and push it forward or pull it towards their arms without expending too much effort.

Also, because the rudder is mounted straight up and down, it can turn a wider range.

If it is not deliberately restricted, it can rotate 360 ​​degrees!

This is why it is much more effective than oars in turning.

After all, the range of left and right rotation of the oar is much smaller.

The emergence of this mature oar and its successful installation on a sailboat took a lot of thought from Bo and others.

When you only look at the results, you will feel that this small change is nothing special, very simple, and anyone can do it.

This is simply easy talk.

Before this layer of window paper is broken, I wonder how many people will be so troubled by this seemingly simple thing that they will lose their hair!

But what makes people feel sad is that there are still many such people in life...

The sails had some adjustments.

Before, the Qingque tribe had this modified sailboat used as a test product. The first sail was a longitudinal sail, and the remaining two were cross sails.

Now the first and second sails have become fore-and-aft sails, and only the third sail near the stern is a cross sail.

And the area of ​​this cross sail is obviously smaller than the two sails in front.

This is the result of the sailors of the Green Bird tribe, who, over a long period of time, have sailed again and again, summed up their experiences, and slowly figured out and made changes.

Two longitudinal sails and one horizontal sail can ensure that the ship can sail with the help of wind from all directions.

And the speed is faster than the other combinations, and the ship is easier to operate.

In fact, the sailors in the tribe tried many combinations before making the sails into the current style of two vertical and one horizontal.

For example, three sails are all longitudinal sails, three sails are all transverse sails, and one longitudinal sail and two transverse sails.

One vertical and two horizontal sheets are divided into the first sheet as vertical, the second sheet as vertical, and the third sheet as vertical, and the rest are horizontal.

After continuous attempts, the people in the tribe finally found that under the current circumstances, the best overall effect would be to make the sails into two longitudinal sails and one cross sail, with the two longitudinal sails in front and the cross sail as the last one.

This is a boring task that tests one's patience.

Fortunately, after these sailors' day-to-day attempts and summaries, good results have been achieved.

After some effort, getting a good result may be an important reason why many people can endure the boring process.

Of course, it’s not the only reason.

For example, in later generations, many people choose to do a job not because they like it so much, but because life has more to offer in the future besides the immediate survival...

Han Cheng stood under a tree by the river and watched the sailors of the tribe maneuvering the boats back and forth for a while, then he walked along the river bank and continued to head down.

After a while, we arrived at the shipyard downstream of the river.

The shipyard was newly built and covers a large area of ​​about ten acres.

Like all residential buildings in the Qingque tribe, this shipyard is surrounded by a wall.

However, there are basically not many houses built inside, only four in total.

The rest are built sheds.

It is made up of pillars made of blue bricks, lime and sand, and sturdy wooden beams.

The wooden beams are similar to the houses built in the tribe, with roofs made of fences, mud, and tiles.

Some of these sheds are used to store wood, while others are used as workshops.

With this kind of shed that is both breathable and rainproof, people working here will feel much better.

In summer, there is no sun and no rain.

But there is also a disadvantage, that is, when it rains, there is no reason to rest, and you still have to continue working...

What to do when it’s cold in winter?

Just find some things to block around...
