Small farmers dominate the deserted island

Chen Yu took the pot and it weighed about a dozen kilograms, but it was a pity that the lid of the pot was not tight and had to undergo secondary processing.

The steam engine is nothing more than the use of the principle of steam leakage.

Fill an iron box with water, then burn it down desperately, and then cover the iron box tightly to prevent a trace of gas from leaking out.

Over time, if you open the lid hastily, it will cause a vapor explosion.

Because the gas inside cannot be discharged, it is no different from plateau gas, and it can even kill people in serious cases.

But Chen Yu would not be so stupid. He would screw the outside of the pot and then figure out a way to twist the lid on it.

Then make a small hole in the pot lid to let the steam leak out. Make sure that the pot and pot lid are relatively strong. Otherwise, if the pot is blown up by the high-pressure gas, the consequences will be disastrous.

As for how to use the steam to twist this huge gear, Chen Yu has no idea for a while, but he can slowly think that as long as there is a source of power, Chen Yu must have a way to turn the winch by itself, just like a car. .

"Brother Green, how much iron can you find here?" Chen Yu asked the green hat next to him.

"Iron! Not much, but I will try my best."

After the Green Hat finished speaking, he quickly organized all the people in the tribe to hand over all the steel that was not needed.

Touba is more direct, holding a big loudspeaker and starting to recycle scrap iron from door to door, even if it is iron slag.

"Recycling, steel, pig iron, all iron-made things, each catty of iron can be exchanged for a sandgrouse."

The tribe is just that big, fart on the upper wind, and the whole village can smell it. After only half an hour, Green Hat and Tuba recovered some iron tools.

Chen Yu made a rough calculation. The total amount of these irons is only a few jins, which is totally unbearable. Moreover, most of these irons have been fire-molded. If they are forged twice, the plasticity is not strong.

"Brother Green, you can't use these things at all, do you have pig iron?" Chen Yu asked.

"What is pig iron?" Green Hat asked.

"Oh, pig iron is iron that hasn't been burnt with fire. It's called pig iron, don't you understand?" Chen Yu looked helpless, and he was struggling to communicate with these indigenous people.

"Pig iron, let me think about it. It seems that when I was young, I passed a place where there seemed to be a lot of pig iron, but that place was already occupied by three tribes. Even if we are a big clans in the past, we will definitely suffer. "The green hat said this, with a look of fear on his face.

"Fear of an egg, now there are ten bows and arrows made by the Touba brothers for you. Are you afraid that you can't do them? And you don't have to attack their tribe. We can kill more prey and go to them to change Iron, I don’t need much iron. I only need five or six hundred catties, but it must be pig iron, otherwise it is not malleable and there is no use for birds.” Chen Yu said.

"Okay, inform all the brothers, gather them all, take out all the food that can be taken out of the tribe, and let's go to the third part of the north to change things." The green hat gave an order, and all the strong men stood out. There were ten of them Carrying the bows and arrows made by Touba for them on their backs, and the others with spears made of bones and weapons made of stones, they set off for the north three in a mighty manner.

Chen Yu was taken aback: This group of indigenous people is really so efficient!I just talk about it casually. They don't even have a plan, so they want to go to someone else's turf to grab something. It's just...simple mind and well-developed limbs.

However, to build desert tanks, iron is an indispensable thing. Chen Yu and Tuba followed more than two dozen people. The green caps walked in the front, carrying a bow and arrow made by Tuba on their backs, and they shot them from time to time on the way. The pheasants and sand grouses of the next grandchildren have a good harvest.

After walking for about 20 miles, they finally reached the so-called North Third.

These three tribes, in the shape of a product, surrounded a small mountain bag in the middle. It could be seen that there should be something precious on the small mountain bag. Otherwise, they would not have built the tribe like this.

As soon as they entered the edge of the tribe, more than thirty barefoot men armed with spears and bows, screamed and rushed out, watching the group of green hats vigilantly.

"Friends, you have crossed the boundary!" said a middle-aged barefoot man, holding his spear across his shoulders, ready to attack.

"No, no, don't get me wrong, we are not crossing the boundary today, but come to your tribe and exchange something with you." The green hat hurriedly put his hands together for fear of conflict.

Although there are more than 20 strong men in his tribe, he does not want to lose anyone. You must know that these are small tribes. The loss of any one person is an immeasurable loss to them, especially He is a strong man and a symbol of the fighting power and status of the entire tribe.

For example, if there are only ten men in a tribe, they can only be regarded as medium-sized tribes in this oasis, and many large tribes can bully them.

If there are only three people, they can only be regarded as small tribes, and anyone can bully it.

However, once the number of people reaches more than twenty people, no tribe dares to underestimate you. A tribe composed of 20 adult men can be regarded as a big tribe in this oasis.

Hearing what the green hat said, the middle-aged man asked, "What do you want to exchange?"

"Oh, we have thirty sand grouses, forty pheasants, and two wild deer. We want to exchange three hundred catties of pig iron from you. If you want, we will put our prey on the ground now." Green hat is careful Said.

The two tribes are about the same size. Once they fight, it is possible that both will suffer. Then the other small tribes will surely come together and attack, and then both of their big tribes may be wiped out.

"What? You want pig iron?" The middle-aged man put down the spear in his hand.

Chen Yu noticed that the guy’s spear was not made of bones, but real steel. It seems that they must have iron ore here. Otherwise, they would not waste steel in this way. On a spear.

"My friend, steel is the foothold of our Northern Tribes. Do you think that just a little bit of prey can be used to exchange our pig iron? However, I think the bows and arrows on the backs of you people are pretty good. A hundred of these bows and arrows come to me, we can discuss and give you one hundred catties of steel." The middle-aged man said.
