“Hoohoo~Hoohoo~”

The fire was burning fiercely.

Heiwa squatted on the side and pushed and pulled a stick in his hand with all his strength.

Tied to the other end of the stick is the pot lid that Heiwa obtained in exchange from his spouse Zhuang after he had put in intense labor.

The size of the pot lid is slightly smaller than the inner diameter of the cylinder.

In order to gather as much wind as possible and send it into the stove, after completing all this, Shi Tou also put a ceramic pipe on the air outlet in the shape of the wind gollum that the Son of God had made before, and extended it all the way to the edge of the stove.

Moreover, the ceramic pipe becomes thinner as it gets closer to the stove.

The joints between several ceramic tubes are sealed with clay to prevent air from escaping.

"call!"

Heiwa pushed the stick in his hand hard, and the force acted on the lid of the pot, which was pushed to the other end of the big ceramic tube.

As he did this, wind gushed out from the ceramic tube, along the channel formed by several ceramic tubes, and went all the way into the stove.

Air rushed into the stove and the flames suddenly grew larger.

If you only look at this, Heiwa's invention is still very successful and has great practicality.

But when Heiwa pulled the lid back, problems arose.

As he pulled it out, the flame inside the stove suddenly became much smaller. If he pulled it harder, the flame inside the stove could even be sucked into the ceramic tube...

This result was obviously not what Heiwa wanted. After pushing and pulling with different strengths for a while, he finally gave up pushing and pulling again and began to squat here, holding his head and thinking constantly.

Judging from the reaction of the fire in the stove when he pushed it out just now, his idea was undoubtedly successful.

The only problem that needs to be solved now is how to prevent the lid from absorbing the air inside the stove when it is pulled out.

After squatting here and thinking for a while, Heiwa stood up and began to remove the mud from one of the joints of the connected ceramic pipes, and pulled it out to create some space between them.

Then push the 'lid' again to send air into the stove.

This time when pulling it out, the flame in the stove will no longer be sucked into the ceramic tube, but new problems will arise.

That is because of the existence of this hole, causing a lot of the gas pushed out by the 'pot lid' to escape through this crack, and the flame is not burning as strongly as before.

After pushing and pulling back and forth for a while, Heiwa stopped again, squatted on the ground, stared at the crack between the two ceramic pipes, and thought about life.

It would be good if the ceramic tubes fit tightly together when you push air in, and the gaps between the ceramic tubes appear when you pull the 'lid' back.

He thought so and operated it manually several times.

But this kind of thing that relies on manual operation is really too troublesome.

Not only does it waste too much time, but the air supply to the stove is also not smooth at all.

After busying himself back and forth like this for a while, Heiwa gave up the idea and continued to squat here thinking about life.

It would be great if the gap would automatically close and open as people pushed and pulled, without anyone having to operate it manually.

This way, there won't be any more trouble...

Heiwa thought like this with full of longing.

But he knew that such a thing would be extremely difficult to achieve because the idea seemed so unrealistic.

It would be great if the Son of God was still in the tribe. The Son of God is so wise, he will definitely find a way to solve the problems he is facing now...

Heiwa once again thought of the Son of God who went to Jinguan City with people to develop and construct there.

After thinking about it for a while, Heiwa shook his head again.

The Son of God is so busy, I can't always expect him to solve everything for me.

Moreover, this matter was related to the firing of porcelain. I was the best person in the tribe in terms of making pottery...

Thinking this way, he continued to try to find a solution and verified his ideas through some operations, but none of them were successful.

That night, Heiwa stayed here until late at night before going back to sleep, but still couldn't come up with any good solution.

At night, Heiwa, who had been lying on the kang for a long time, was undoubtedly suffering from insomnia.

Taking this natural sleeping pill to solve insomnia seems to be a skill that many people know and can learn without any guidance.

After shaking Zhuang awake and letting him feed him a dose of sleeping pills, Heiwa, with his mind in a mess, quickly fell asleep...

The next day, Heiwa, the master pottery maker, came to the carpenter's room and told Bo about the difficulties he encountered and the possible effects that might occur if the problem was solved. He wanted Bo to help him think of a solution to see if the problem could be solved.

After all, Bo created more things, and many of them were very complicated.

After hearing Heiwa's story, Bo's interest was immediately aroused. As a carpenter who was in a lonely position, Bo liked all kinds of difficult things the most.

Although the process of solving a problem may make people feel very painful, and in serious cases, they may even want to bang their heads on the ground, but it must be said that when the problem is finally solved through various efforts, that feeling is really great!

Not to mention the refreshing feeling, it makes people feel like drinking fairy wine, enough to make people ignore the difficulties that may be encountered in the process.

So Bo agreed without much hesitation and said that he would work with Heiwa to find a solution.

I am a carpenter, so when solving problems, I will naturally think from the carpenter's perspective.

After watching the simple device made by Heiwa with Heiwa and figuring out its principle, and staying here for a while, Bo returned to the carpenter's room.

After sitting in the carpentry room and thinking for a while, he began to work busily with the tools.

After a while, a hollow rectangle appeared in Lame's hand.

The reason why he made it into a rectangle was because he had tried to make a round wooden barrel or something like that with wooden boards before, and he knew that it was very difficult to make these things with wooden boards, so he chose a cuboid.

Anyway, he had already figured out the principle and function of the device that Heiwa wanted to make, so it didn't matter if he replaced the hollow cylinder with a hollow rectangle.

Placing the unsealed rectangular block on the ground, Bo started to cut wooden boards with a saw, imitating the long-handled 'pot lid' made by Heiwa, and made something that could be put into the middle of the hollow rectangular block and pushed and pulled.

After it was done, I put it in and pushed and pulled it a few times at the other end, but the effect was not good.

The main problem is that there is no seal on the other end. If you don't control it well, this piston-like thing will come out from the other end.

So Bo found a piece of wood and sealed the other end of the hollow rectangle.

After sealing it, I tried pushing and pulling it, and the effect was good.

This piston-like thing will no longer come out from the other end.

But at the same time, the pushing wind will not go out from there, but will run upwards along the gap between the wooden piston and the inner wall of the wooden box.

This kind of thing was too difficult for Bu Bo, so after pushing and pulling it a few times, he picked up the tools and made a hole in the bottom of the wooden box for ventilation.

With this hole, pushing and pulling becomes much more convenient.

At this point, the problem that Bo needs to face is the same as that Heiwa needs to face, which is how to solve the problem of automatic closing of the gap or the hole at the bottom of the wooden box.

This is also not an easy problem to solve for Lame.

If the problem was really that easy to solve, Heiwa wouldn't have been put in such a difficult situation and asked him for help.

After working in the carpenter's room for a whole day and exchanging ideas with Heiwa who had been busy in the manufacturing workshop for a whole day, Bo still had no inspiration and could not find a solution.

The turning point came the next day.

A chilly wind blew by, and the persimmon leaves that had turned red but still stood stubbornly on the branches, refusing to fall, swayed left and right in the cold wind.

After a struggle, it finally couldn't withstand the cold wind and fell from the sky in a spiral.

Some minors, dressed like little balls, ran over, picked up the fiery red leaves, held them in their hands, and jumped around randomly, giggling.

After playing with it for a while, some minors developed new ways to play with it.

That is to put the leaf under the nostrils, inhale the leaf so that it sticks to the nose and does not let it fall, and see who can suck it for longer.

Of course, this can only be done by inhaling hard, if the nose is stuck with mucus it doesn't count.

Otherwise, some minors with innate skills like Erchong would definitely win.

When these children play this game, they need to clean their snot first.

Lame, whose mind was full of thoughts on how to solve the problem, shook his dizzy head vigorously and stopped thinking about the matter. Instead, he focused his attention on the children here and watched them play games with a smile, in order to change his mood and make himself calm.

After looking at it for a while, Lame's eyes suddenly brightened, as if something passed through his mind, bringing out some light.

He watched these children playing and laughing with excitement, his heart became more and more open, and the thing that flashed by was gradually caught by him.

After standing here for a while, he ran back to the carpenter's room like the wind. His speed was so fast that even a normal person with nimble legs and feet could hardly match him.

After returning to the carpenter's room, Lame sat there and thought for a while before taking action.

Instead of using the tree leaf that gave him inspiration, he cut off a small piece of smooth animal skin.

The hide was larger than the hole in the bottom of the box.

After some operations, the lame general nailed the piece of animal skin to the hole with copper nails.

Of course, it was not nailed completely, only one side.

After nailing it in place, Lame reached out and grasped the handle of the wooden piston, then pushed it forward excitedly.

As he moved, the wooden piston was pushed forward, and the air was squeezed to form wind, which blew away the animal skin covering the outside of the wooden hole, allowing the air inside to come out smoothly.

After pushing the wooden piston to the bottom, Lame pulled it upwards.

The effect is just as I imagined.

Because this small piece of animal skin was nailed on one side with a copper ingot, so even if it was stationary, it was basically covered with only a few gaps.

So as Lame pulled the wooden piston upwards, the small piece of animal skin immediately stuck tightly to it, fitting perfectly.

This discovery made Bo very happy, because he really created a tool that could automatically open or close the gap as people pushed or pulled.

But this happiness did not last long, and new problems soon emerged.

That is, once the hole here is completely blocked, it becomes difficult to pull the wooden piston back.

It would be fine if you use little force and move slowly, but if you use too much force, you might even suck the other side of the softer animal hide from the outside into the wooden box.

After it is sucked inside, it is no longer possible to open and close it with pushing and pulling as before.

The emergence of such problems can only mean one thing, that is, this tool is not yet ready and needs to be further improved.

"Try making another hole in the bottom."

Heiwa, who came from the pottery workshop after hearing the news, pushed and pulled the wooden piston excitedly for a while, then fell into deep thought and began to consider with Bo how to solve the problem.

After thinking about it for a while, he spoke tentatively.

Lame didn't have any good idea, so after thinking for a while, he decided to try what Heiwa said.

He pulled the wooden piston completely out of the wooden box, then picked up the axe and chisel and began to open the hole not too far away.

It didn't take long before a new hole was chiseled out.

Installing a wooden piston and pushing and pulling it back and forth a few times did not solve the problem.

With this hole, it is easier to pull the wooden piston back, and the animal skin covering the first hole will not move inside, but other problems will also arise.

For example, when the cork is pushed forward, most of the wind generated escapes from the newly opened hole.

However, things have come to this point now, and the remaining problems will definitely be solved. It is just a matter of time.

Sure enough, it didn't take long before Bo tried to bind the leather with the newly opened hole.

At first it was bound on the outside, but it soon became apparent that this did not help.

So I took off the leather, covered the hole with it from the inside, and nailed it on one side with a copper nail...
