I am a primitive

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

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

So Lai agreed without much hesitation, saying that he would work with Hei Wa to find a solution.

Lame is a carpenter, so when solving problems, he will naturally think from the perspective of a carpenter.

After watching the simple device Hei Wa made together with Hei Wa, and figured out the principle of this thing, after staying here for a while, Limp returned to the carpenter's room.

After sitting in the carpenter's room and meditating for a while, he began to work around with the tools and began to clang.

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

The reason why he made it into a rectangular shape is because he had tried to make a round wooden barrel with wooden boards before. Knowing that it is very difficult to make these with wooden boards, he chose a rectangular parallelepiped.

Anyway, he has already figured out the principle and function of the appliance that Hei Wa wanted to make, so it doesn't matter if the hollow cylinder is replaced with a hollow cuboid.

Put the two unsealed cuboids on the ground, and then use a saw to cut the boards, imitating the one made by Heiwa with a long-handled 'pot cover', and made a one that can be put in the middle of the hollow cuboid for pushing and pulling s things.

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

The main reason is that there is no seal on the other end, and if the control is not good, this piston-like thing will come out from the other end.

So Lai found a piece of wood to seal the other end of the hollow cuboid.

After sealing it, I tried to push and pull it, and the effect was good.

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

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

Such a thing could not help but limp, and after pushing and pulling a few times, he picked up the tool and made a hole in the bottom of the wooden box for ventilation.

With this hole, it is much more convenient to push and pull.

At this point, the problem Lai needs to face is the same as Hei Wa needs to face, how to solve the problem of the gap or the automatic closing of the hole at the bottom of the wooden box.

This is also not a good solution for lameness.

If it was really that easy to solve, Hei Wa wouldn't be embarrassed to ask him for help.

After working in the carpenter's room for a day, and exchanging ideas with Hei Wa, who had been working in the workshop for a day, he still didn't have any inspiration and couldn't find a solution.

The turnaround came the next day.

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

After a lot of struggle, it finally couldn't hold back the entanglement of the cold wind, and fell from the air in a whirl.

A minor dressed like a small ball ran over to pick up the fiery red leaf and held it in his hand, jumping around and giggling.

After holding it in his hand for a while, some minors developed new ways to play.

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

Of course, this can only be done by inhaling hard, and the sticky nose doesn't count.

Otherwise, some minors with innate skills like the second worm would definitely win.

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

Lame, whose mind was full of how to solve the problem, shook his drowsy head vigorously, no longer thinking about this matter, but focused his attention on the children here, watching these children playing games with a smile, in order to Come to change your mood and let yourself become calm after all.

After looking at it for a while, Limp's eyes suddenly lit up, as if something flashed through his mind, bringing out some light.

He watched these children laughing and joking here with excitement, and his heart became more and more open. 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. Even a normal person with good legs and feet could hardly compare with that speed.

After returning to the carpenter's room, I limped here and thought for a while before starting to act.

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

The hide is bigger than the hole in the bottom of the wooden box.

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

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

After nailing it, Liao stretched out his hand to hold the handle of the wooden piston, and then pushed it forward excitedly.

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 wooden hole, and the air flow inside could come out smoothly.

After pushing the wooden piston to the bottom, the lame pulled it up again.

The effect is as lame imagined.

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

So as Liao pulled up the wooden piston, the small piece of animal skin immediately stuck to it tightly, and it fit perfectly.

Such a discovery made Liao very happy, because he really made a tool that can automatically open or close the gap as people push and pull.

But this joy did not last too long, and new problems soon followed.

That is, after the hole is completely blocked, it will become laborious to pull the wooden piston back.

The force used is small and the movement is relatively slow. If the force is too large, the other side of the softer animal skin will even be sucked into the inside of the wooden box from the outside.

After inhaling into the inside, it is impossible to let it open and close as it is pushed and pulled as before.

Such problems can only explain one thing, that is, this tool has not been completed yet and needs to be further improved.

"Try another hole in the bottom."

Hei Wa, who came from the pottery workshop, was full of excitement and pushed and pulled the wooden piston for a while, then fell into deep thought, and began to think about how to solve this problem with Lai.

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

There is no good way to be lame. After thinking about it for a while, I decided to try the method Hei Wa said.

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

It didn't take long before a new hole was limp-gouged.

Install the wooden piston and push and pull it back and forth a few times, but the problem has not been solved.

With this hole, it is easier to pull the wooden piston back, and the animal skin covering the first hole will not go in again, but the rest of the problems also appear.
