"What do you say? Chief, you're not lying to us, are you? It's true? Elder Shi grabbed Chu Nan's hand, his whole body trembled with excitement, and he looked at Chu Nan in disbelief, although he knew that his chief would not deceive people, but when he thought of what the chief said, he still couldn't believe it.

There are already methods of making iron and steel, and as long as they make steel, they can make tools and weapons that are thousands of times better than stone and bone tools, and they can make things much faster.

If it weren't for their own chieftain, they would have been kicked out, or even beaten.

No matter what it is, it has to be done step by step, how can it be said that there is one?

They have worked hard for so long, and they have only made something new, but it is extremely slow, and now someone has told him, you can't do those things, and I will immediately conjure up a thousand times more powerful things for you.

How many years have we all lived together, and who doesn't know who? What the fuck are you playing with me?

But it was the chief who spoke, and it was different, whether it was the stone or the young apprentices, they all put down their work and gathered around, looking at the chief with blazing eyes.

If others say they don't believe it, but as long as it is the chief who says it, they believe it, because their chief is omnipotent, and if he says it, it must be true.

"Of course it's true, Elder Stone, you still have to continue to recruit people, although we don't produce on a large scale, but the number of people can't be too small, as for mining or something, let those people of other races who are obedient do it, as long as they do a good job, they can become members of our Tianhuo clan, not only now, but also in the future, but all foreign races who are obedient must pass the test, and only by contributing to our Tianhuo clan can they be qualified to become our Tianhuo clan." Chu Nan glanced at the alien people who were still working in the distance, there were nearly a hundred people, and showed a sneer.

Shi nodded, suppressed the excitement in his heart and said, "Our elders have already formulated some standards, and only the chief is left to nod, but you haven't had time to show you this time." ”

"That's good, call a few hundred people to go with me first, by the way, call a few hundred soldiers, and no one will clean up the mess in the province." Chu Nan took the lead and walked towards the open-pit mine, which had been taken care of at this time, although he knew that no one dared to come, he couldn't be unguarded.

Seeing that he came out and led hundreds of people to come, the soldiers in charge immediately saluted Chu Nan.

"Well, you guys keep watch around, and you come in with me." Chu Nan led the people of the other races who returned to Shun to a relatively flat place, intending to build an iron-making furnace here.

After understanding, he already knew that the quality of ironmaking was related to the temperature, and the quality of ironmaking in ancient China was not too good, mainly because the temperature could not be raised, and the power of the blowing tool was too small.

Chu Nan is already optimistic, where the blast furnace is built, there is a small river that is not too big, but it is enough to push the windmill and blow the blast furnace, as long as the wind is enough, and there is enough charcoal, it is not difficult to refine higher quality iron.

Saying that it will be built, Chu Nan already has a score in his heart, drawing the blast furnace into drawings, and slowly explaining to Shi Shi and others, these people have been in initial contact with the drawings, although they can't fully understand the things on it, but they can still do it.

At this time, the furnace for building ironmaking can only be built up with huge stones on the outside, and then the inner wall is made of soil inside, and the inner wall is more than one meter thick, because the melting point of stone is much lower than that of soil, under normal circumstances, more than 1,000 degrees will begin to melt and become liquid, the melting point of soil is generally 1500 to 2,000 degrees, if the soil has no other impurities, it is generally 2,000 degrees, and the temperature of ironmaking needs 1,500 to 2,000 degrees, and in this case, it is good to be able to raise the temperature to 1,500 degrees.

Therefore, using clay to make the inner wall of the ironmaking furnace is a very good choice.

Unless tungsten metal ore can be found, its melting point can reach more than 3,000 degrees, if it is used for the inner wall, it is the best choice, but for Chu Nan at this time, he can only think about it, and it is impossible to achieve it.

Chu Nan felt that he didn't look like a traverser at all, in his impression, all traversers were pig's feet, and they were in the middle of hanging all their lives, and they hung one after another, they had what they wanted, and they came what they lacked.

How can he be so hard-working, although he is a traverser, he has the knowledge and insight beyond this era, but no matter what he makes, he has to do it himself, and what is even more bitter is that he is not thinking about anything, he has to work hard to find it, such as the materials for making linen, which have not been discovered until now, iron smelting and copper, how long has I been thinking about it, and it is only a little progress now, and it is still early to use iron tools on a large scale.

Chu Nan directed the construction of the iron-making furnace while thinking about the problems he would encounter.

Because there was no coal for ironmaking, it was only possible to make charcoal in large quantities, but fortunately, there were many woods that had not been burned out dozens of miles away from the territory, and now they are used to make charcoal, saving time and effort.

Just to make enough iron and steel, just using charcoal is not an option, even if a lot of charcoal has been accumulated, it will not take long to consume it.

After more than ten days, two iron-making furnaces were built, each covering an area of ten meters in size and four meters high, and a slag opening was made, which can be said to be very advanced and beyond this era.

Because the iron-making furnace was extremely demanding and could not crack, it took more than ten days to build.

The next step was to build a waterwheel to drive the blower and provide a strong enough air to the furnace so that the temperature was high enough to melt the iron ore and get a relatively good piece of iron.

If the temperature is not enough, the iron will be honeycomb-shaped, and then it will be forged to get iron, and if you want to get steel, you need to continue to forge and remove the carbon material inside, and you will get steel, which is the so-called 100 refining into steel.

Making a waterwheel is much easier and easier than building an iron-making furnace, and the final result is to build a wind furnace that is connected to the waterwheel.

The principle of the wind stove is also very simple, that is, to make a few large pieces of wood into a windmill, and then seal, the wind can blow the windmill, and the windmill can also blow up the wind when it rotates, and the waterwheel drives the wind stove to blow is this principle.

It's easy to say, but it's more troublesome to build, or because the tools are too backward, and you want to make some precision, it's impossible, and finally I got a similar windmill, tried it once, and it felt like it, so I used it first, and then made iron, with saws, axes, chisels and some other carpenter's tools, and then improved the windmill, and then the iron smelted at that time would be better, and the speed would be faster.
