The last dragon ever

Chapter 241 The IQ of Ancient People
Yang Luyun felt that she really underestimated the IQ of ancient people.The windmill was made of pure wood, and she provided the rough version of the instructions, so she was not surprised that they were able to make it.She taught the hoe for digging the ground, but the head of the hoe used to be made of stone, and now this kind of "iron head" is not taught by her.

I rely on!

When she didn't notice, these guys actually got the iron out? !
It turned out that with the development of the tribe, some small tribes often came to the tribe to exchange things with them, and their tribe had a faint reputation in the south of the wild continent.By chance, a small tribe discovered that a black stone with golden color was very sharp and could be used as a weapon.

In order to be able to exchange with the Shenlong tribe and get more protection, they offered this kind of thing.

When the people in the tool department got this kind of thing, they found that they couldn't make it with the convenience of making stone tools, so they imagined making wood, bamboo, etc., which are baked and burned, and are softer and easier to process.I don't want the fire to be too small to have any effect, but too big to burn? !

It scared them enough. Fortunately, there are enough black stones, and it doesn't matter if one of them is broken.

But one of them found that the melted black stone fixed its shape after cooling, and its hardness was about the same as before.So he thought, since it will be fixed when it is melted and cooled, does that mean they can make a mold and pour the burnt black stone into it, and it will be finished?

Just do it when you have an idea, and after a few tries, you can make a lot of things-hoe heads, knives, arrows, hammers, etc.

Yang Luyun said with a wooden face: "Since you have already made iron, how about it, I will teach you how to make tools for plowing the fields. I heard from the person in charge of farming that the rice fields specially left over there have begun to sprout. We There is still a large field that has not been cleared..."

She knows the general shape of a plow. It has a triangular pear head made of iron. The lower end is close to the ground and can plow into the ground.There is a joystick behind the buttocks, and a person controls it and straightens the plowshare.There is also a relatively short operating rod in front, which is a little distance from the plowshare, and it is convenient for the person in front to pull it, so it is safer.

"Originally, the operating lever in the front place could be pulled by animals, but because we don't have animals that can drag things in modern times, it can only be operated by humans. That is to say, when plowing the field, we need two people, one standing in front and dragging forward , one stands at the back to operate, what you need to pay attention to is the position of the plowshare, it is pointed and can hurt people, the front position must be enough, be careful not to hurt the people in front, and the animals that will be used to plow the field in the future .Before it is really ready, you can not make this plowshare and replace it with other things, and then install it after the structure is no problem...Even if it is an experiment, it can't hurt people, understand?"

In Yang Luyun's mind, the plow is really dangerous. She always feels that if the person walking in front is not paying attention, he may be poked by the plowshare, but this is not an irreplaceable plowing tool. So she can only emphasize the safety issue again and again.

"If this is touched, the foot will be useless. The men in the tribe are the main force of work. If he loses his feet, he will not be able to work in the future. It will be a great loss to the tribe. I allow you to do it. Do experiments with new things, but it must be under the condition of ensuring the safety of personnel. If it is not safe, I would rather not make new things, understand? People are the most important wealth of the tribe."
