What should I do if I accidentally come to the ancient times?

Naturally, Cangwu couldn't be bothered with this question. You know, he has been wandering around the mountains and forests around the Heishi tribe with the young and strong members of his clan for 30 to [-] years.

Soon, he brought Zhao Hao to a barren mountain less than an hour away from the Black Stone Department, where the mountain was almost covered with reddish-brown stones.

Zhao Hao ran over and randomly picked up a piece and looked at it. He was so excited, that's right, the stones here are iron ore, and there are iron ore all over the mountain!

Of course, this iron ore cannot be used as iron. It is not easy to extract the pig iron inside.

Zhao Hao had never done this kind of work in his previous life, but he had seen it on TV. Iron making probably means putting iron ore and coal together and burning them vigorously. When the burned iron ore melts, the pig iron inside will burn. It turns into molten iron and flows out.

Such a seemingly simple process requires a lot of preparation.

First of all, there must be a stove. Ordinary stoves are not enough. It must be a stove made of clay. Moreover, the stove must be quite strong. No need to burn, the furnace will be fractured directly.

This stove, according to the current level of the Black Stone Department, is logically impossible to manufacture, but Zhao Hao came up with a good idea.

This method is also simple to say, that is, dig a big hole on the hillside, then fill in a thick layer of clay around the hole, then dig a hole under the hole, and finally make a thick layer like a water tank. Just put the clay pot in the hole to catch the molten iron.

It's not difficult to prepare these things. Digging pits is Zhao Hao's specialty. Clay is abundant near the Black Stone Department.

These things were prepared in roughly one day, and then Zhao Hao stuffed a large pile of coal into the stove and burned it all night, and the stove was almost pottered.

Early the next morning, Zhao Hao began experimenting with refining pig iron.

He also doesn't know what the ratio of coal to iron ore is. In short, it is right to put more coal and less iron ore. Anyway, he is experimenting at this moment, not mass production.

He directly stuffed five or six hundred catties of coal into the stove, and put a lot of firewood underneath, but only about one hundred catties of iron ore was stuffed in.

Everything is ready, just light the fire directly in the hole under the stove, because there is a hole leading to the stove in the hole under the stove, after all, the molten iron has to flow out of the stove, right?

Not long after the fire in the cave was lit, the firewood in the stove was lit, followed by a long waiting process.

This time, Zhao Hao burned for most of the day.

Unfortunately, until all the coal in the stove was burnt out, there was still not even a drop of molten iron dripping from under the stove!

What is going on here?

It seems that the temperature is not enough!

So, how to increase the temperature inside the furnace?

Zhao Hao thought about it for a long time, and finally remembered that in some costume dramas, when building weapons, there is a big bellows next to the stove, which constantly pours air into the stove.

This bellows cannot be made at the current level of the Black Stone Department, but Zhao Hao thought of a good way.

This method is also very simple, that is, cut a big tree thicker than the waist, take a piece of trunk, hollow out the inside with a magic sword, and then plug a cork that is about the size of the hole inside, and make Come out with something like a needle syringe.

After the syringe made of the tree trunk was finished, he dug a hole next to the stove and stuffed the trunk directly into it, and then he made a small hole in the corresponding position next to the stove body. Ready.

On the third day, he prepared a large pile of firewood and five or six hundred catties of coal. This time, he prepared dozens of catties of iron ore.

Everything was ready, and he started to light the fire again.

However, this time, he didn't stand by and wait. He kept holding the big wooden stick drawn out from the tree trunk, and quickly pushed the piston, continuously pouring wind into it.

This guy, as soon as the wind poured in, the fire in the furnace became more prosperous, and the flames jumped several meters high.

This time, the burning speed of the coal in the stove was also significantly faster. In less than two hours, the coal inside was almost burnt.

After much difficulty, when all the coals in the stove were burnt out and the fire was almost extinguished, he dropped the wooden stick and carefully dragged the thick clay pot under the stove out of the hole.

It worked!

Although there was not much molten iron in the thick clay pot, about as much as a ladleful of water, he did extract the molten iron.

Although the molten iron does not look very pure, and there are even some scum of unknown composition in it, but it is indeed molten iron!

Seeing the gradually cooling molten iron in the thick clay pot, Zhao Hao couldn't help but feel emotional, Nima, it's really not easy to make some inventions and creations, it's even harder than hunting strange beasts that are close to divine beasts!

Chapter 86 A Hammer

The molten iron finally cooled, and Zhao Hao carefully poured it out of the thick clay pot, as if it contained rare treasures.

Of course, the reason why he was so careful was not because he was afraid of breaking the iron lump inside, but because he was afraid of breaking the thick clay pot outside.

This is the pottery burning place of the Black Stone Department. At this moment, Cangwu is digging holes here with thousands of elites. Zhao Hao's actions naturally attracted the attention of many people, including Ayun and Ayue. Inside, everyone was curious, what kind of treasure was made this day?

When a strange-shaped iron bump appeared in front of everyone, almost everyone was taken aback, but Zhao Hao was dancing with excitement.

This!

what is this baby?

Everyone really couldn't see what was so rare about this thing, but Zhao Hao held it in his hands and touched it, looked at it again and again, it was really like a treasure.

Is the leader sick today!

Cang Wu couldn't help but stepped forward and asked, "What's the use of this thing?"

This thing, of course, is useless!

Just kidding, what's the use of an iron bump.

Pig iron, it has to be made into various utensils to be useful!

Zhao Hao shook his head without hesitation and said, "This thing is useless."

Cangwu couldn't help being dumbfounded when he heard this.

You said that you spent the past few days working hard to come up with such a useless thing, and you are still so happy. Are you really sick?

Zhao Hao didn't bother to explain it to Cangwu, because it was impossible to explain things like iron smelting to people of this era. It was still the old way, as long as they made something, they would understand.

So, how to process this pig iron?

There are no processing centers these days, and the only way to process pig iron into various utensils is to smash them with a hammer!

This method has a well-known name, that is "strike the iron".

However, if you want to forge iron, you can't do it without a hammer.

Moreover, a hammer alone is not enough, because the pig iron has to be hot to process, and the hot iron bumps cannot be handled with hands, and a clamp must be made to hold them.

This is a bit troublesome again, just like the question of which came first, the chicken or the egg.

How can eggs be laid without chickens?
