"Huhu~Huhu~"

The fire was blazing.

Heiwa squatted on the side, pushing and pulling a stick hard.

The other end of the stick is tied to the pot lid that Heiwa has obtained from her spouse Zhuang after exerting intense labor.

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

In order to gather as much wind as possible and send it into the stove, after this was completed, the stone was also covered with a clay pipe at the air outlet in the shape of the wind gurgling that Miko had made before, and extended it all the way to the edge of the stove.

And this clay pipe is still the kind that gets thinner the further you go to the stove.

The interface between several pottery pipes is sealed with clay to prevent it from running out.

"Whew!"

Heiwa pushed hard against the stick she was holding, and the force applied to the lid of the pot, which was pushed to the other end of the large clay tube.

With this movement, a wind gushed out from the clay pipes, and led all the way to the stove along the passage formed by several clay pipes.

The air poured into the stove, and the flames suddenly grew louder.

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

But when Heiwa pulled the lid back to the bottom, the problem arose.

As he pulled out, the flame in the stove suddenly became much smaller, and if he pulled harder, the flame in the stove could even be sucked into the clay pipe......

This result is obviously not what Heiwa wants, and after pushing and pulling here with different forces for a while, he finally gave up pushing and pulling again, and began to squat here holding his head and constantly thinking.

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

The only problem that needs to be solved now is how to pull the lid out of the pot so that it does not suck the gas from the stove.

After squatting here and thinking for a while, Heiwa stood up and started to remove the mud from one of the joints of the pottery pipes connected to each other, and pulled them out, leaving some gaps between them.

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

This time, when it was pulled out, there would be no more flames from the stove being sucked into the clay pipes, but new problems would arise.

That is because of the existence of this opening, a lot of the gas pushed out with the 'pot lid' ran away along this crack, and the flame burned not as strongly as before.

After pushing and pulling back and forth like this for a while, Heiwa stopped her movements again, squatted on the ground and stared at the crack between the two pottery pipes to think about life.

It would be nice if the clay pipes were tightly fitted when you pushed the air inside, and when you pulled the lid back, the gaps between the clay pipes would come out.

He thought so and did it manually a few times.

But this kind of manual operation is just too cumbersome.

It's a waste of time, and the gas supply to the stove is not coherent at all.

After working back and forth like this for a while, Heiwa gave up this idea and continued to squat here and think about life.

If you don't have to use your hands to operate it, the gap will automatically close and open as you push and pull.

That way you don't have to go through the hassle......

Heiwa thought with longing like this.

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

If only the Son of God was still in the tribe, and the Son of God was so wise, he would definitely have a way to solve the problems he was encountering now......

Heiwa once again remembered the god son who went to Jinguan City to take people to develop and build there.

After thinking like this for a while, Heiwa shook her head again.

The Son of God is so busy, he can't always think about everything and let the Son of God solve it.

Moreover, this matter is related to the firing of porcelain, and he is the most powerful person in the tribe in terms of making pottery......

Thinking so, he continued to think of ways here and tested his ideas through some operations, but none of them were successful.

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

At night, the black baby who had been lying on the kang for a while undoubtedly had insomnia.

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

After shaking Zhuang awake and letting Zhuang feed him a dose of sleeping pills, the black baby who was in a mess in his mind quickly fell asleep......

The next day, Heiwa, a master of pottery, came to the carpenter's room and told Lame about the problem he had encountered, as well as some of the possible effects if this problem was solved, and wanted Lame to help him think of a way to see if he could solve this problem.

After all, there are more things made by lameness, and many things are very complicated.

After listening to Heiwa talk about this, Lame's interest was immediately mobilized, as a carpenter in a high place, Lame's favorite thing is all kinds of difficult things.

Although in the process of solving the problem, it may make people feel very painful, and when it is serious, they even want to make people grab their heads for the ground, but I have to say that through all kinds of efforts, when the problem is finally solved, that feeling is really very cool!

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

So Lame didn't hesitate much, so he agreed to it, saying that he would find a way with Heiwa.

Cripple is a carpenter, so when solving a problem, he will naturally think from the carpenter's point of view.

After watching the improvised device that Heiwa had made and figuring out the principle of this thing, he stayed here for a while, and then returned to the carpenter's room.

After sitting in the carpenter's room and pondering for a while, he began to work on the tools and began to jingle and get busy.

After a while, a hollow cuboid appeared in the limp hand.

The reason why he made it into a rectangle was because he had tried to make a round barrel out of wooden planks before, and he knew that it would be difficult to make these with wooden planks, so he chose a cuboid.

Anyway, he has already figured out the principle and function of the kind of instrument that Heiwa wants to make, and it doesn't matter if he replaces the hollow cylinder with a hollow cuboid.

The cuboid with no seal at both ends was placed on the ground, and the limp began to cut the plank with a saw, imitating the one made by Heiwa with a long-handled 'pot lid', and made something that could be put into the middle of the hollow cuboid for pushing and pulling.

After it is done, put it in and push and pull it to the other end a few times, but the effect is not good.

The main thing is that there is no seal at the other end, and if one is not well controlled, this piston-like thing will come out from the other end.

So the lame found a wooden board and sealed the other end of the hollow cuboid.

After sealing it, I tried to push and pull it, and it worked well.

This piston-like thing won't go out of the other end anymore.

But at the same time, the wind that pushed it didn't go out of there, and it all ran up the gap between the wooden piston and the inner wall of the wooden box.

It was so hard to be lame, and after a few pushes and pulls, he picked up his tools and made a hole in the bottom of the wooden box for ventilation.

With this hole, it is immediately much easier to push and pull.

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

Again, this is not a good thing to solve for lameness.

If it was really that easy to solve, it wouldn't be embarrassing for Heiwa to come over and ask him for help.

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

The turnaround came the next day.

The cold wind blows, and the persimmon leaves, which have turned red but still stand tenaciously on the branches and refuse to fall, sway from side to side in the cold wind.

After some struggle, in the end, he couldn't resist the entanglement of the cold wind, and fell from the air with a whirl.

There were minors dressed like small round balls, who ran over and picked up the flaming red leaves and held them in their hands, jumping around and giggling with laughter.

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

That is to put the leaf under the nostrils, and by inhaling the leaf and stick it to the nose to prevent it from falling, to see who can suck it for a long time.

Of course, this can only be done by inhaling hard, and the snot sticking does not count.

Otherwise, some minors who have natural skills like two insects will definitely be able to win.

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

His mind was full of how to solve the problem, and he shook his drowsy head vigorously, no longer thinking about it, but focusing on this child, smiling and watching these children play games, in order to change his mood and make himself calm after all.

After looking at it like this for a while, his lame eyes suddenly lit up, as if something was passing through his mind, bringing out some light.

He watched these children giggling and playing here with excitement, and his heart became brighter and brighter, 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, a speed that even a normal person with dexterous legs and feet could hardly match.

After returning to the carpenter's room, he sat here with a limp and thought for a while before he began to act.

Instead of using the leaves that inspired him, he cut out a small piece of bare hide.

The hides are larger than the hole in the bottom of the wooden chest.

After some manipulation, the skin was lame and nailed to the hole with a copper nail.

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

After nailing it up, the limp reached out and grabbed the handle of the wooden piston, and then pushed forward with excitement.

With his movements, the wooden piston was pushed forward, and the air was squeezed to form a wind, blowing away the animal skin covering the outside of the wooden hole, and the air flow inside could come out smoothly.

After pushing the wooden piston to the end, the limp pulls it up again.

The effect is the same as if it was lame.

Because the small piece of the skin itself was nailed to one side with a copper ingot, even if it was stationary, it was basically covered with only a few gaps.

So as the lame pulled the wooden piston up, the small piece of animal skin immediately clung to it, tightly sealed.

This discovery made the cripple happy, because he really made a tool that could automatically open or close the gap with the push and pull of a person.

But this euphoria did not last long, and soon new problems arose.

That is, when the opening is completely blocked, it becomes laborious to pull the wooden piston back.

If the force is too high, the other side of the softer animal skin will be sucked into the inside of the wooden box from the outside.

After inhaling inside, it is impossible to let it open and close as you did before, as you did before.

Such problems can only show one thing, that is, this tool is not yet done well, and it needs to be improved.

"Try making another hole in the bottom."

Heiwa, who heard the news from the pottery workshop, was full of excitement and pushed and pulled the wooden piston for a while, and also fell into deep thought, and began to think about how to solve this problem with the lame.

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

There is no good way to be lame, and after thinking about it for a while, I decided to try it according to what Heiwa said.

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

It didn't take long for a new hole to be chiseled out with a limp.

Installing a wooden piston and pushing and pulling back and forth a few times, the problem was not solved.

With this hole, it was easier to pull the wooden piston back, and the skin covered outside the first hole would not go any further, but the rest of the problems would arise as well.

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

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

Sure enough, it didn't take long for the limp to try to bind the newly opened hole.

At first, it was bound outside, but it soon became clear that this was not helpful.

So he removed the skin, covered it with the hole from the inside, and nailed it to one side with a copper nail......
