The next day all the work was ready, Lu Ya came to the blast furnace early, and told Xiong Da and Xiong Er to put the firewood and iron ore into the blast furnace, Lu Ya personally threw the torch into the blast furnace, the dry and fat pine firewood was soon ignited and the fire grew, as soon as the furnace door was closed, Lu Ya waved his hand, Xiong Daxiong and Xiong Er began to pull up the four air boxes placed around the blast furnace, and the vent that was still emitting wisps of green smoke first burst out of a black smoke, and then an orange-red flame turned out, and the color gradually faded as the two kept pulling the flame, gradually turning blue, causing the air around the flames to distort for a while.

Seeing this change, Lu Ya also breathed a sigh of relief in his heart: "In the ancient period when the industry was underdeveloped, the main reason why people rarely used iron tools was that it was difficult to melt its raw ore, and the smelting equipment of the blast furnace solved this problem very well, put the ore and fuel into the blast furnace and use the bellows to inject sufficient air into it to support combustion, and the iron ore could be melted at a continuous high temperature, and the most primitive molten iron was obtained."

The blast furnace continued to burn for more than an hour, during which a one-man high firewood pile was fed into the furnace, and at this time, the blast furnace's molten iron outlet finally flowed red molten iron. This molten iron was brighter and purer than the molten iron smelted by the old man, and although there were still some black-brown magazines floating on it, Lu Ya still felt very satisfied, and after filling three pre-made pottery pots, the ironmaking was finally over.

At this moment, Lu Ya is surrounded by a lot of clansmen, Xiong Da Xiong Er, Iron Old Man, Carpenter, Bai Lifu and some people who have nothing to do have come here, Lu Ya has been busy up and down these days, everyone is very curious about what he is doing, so when they heard that there is going to be an experiment today, everyone also came to watch, when they saw Lu Ya put a bunch of stones into the furnace, everyone still didn't understand what they were doing, but when the red molten iron flowed out, someone around finally exclaimed, "It's molten iron!" Oh my God, this strange furnace can melt iron ore," exclaimed a clansman who had seen others smelting iron.

"yes, and it's magic to melt the raw ore so quickly," another person was shocked by the speed of the iron smelting.

"And don't you find that this method of refining is more economical than other people's refining?" an attentive clansman noticed a problem with the quantity of wood used.

Everyone, you and I expressed the surprise in their hearts one by one, this novel iron-making technology opened their eyes, and many people knew that it was possible to make iron in this way, and it seemed to work well.

After the molten iron in the three molds was almost cooled, Lu Ya threw them all into the water tank, and after a burst of water mist, the grinding tool shattered, and three 'spearheads' with black surfaces appeared in Lu Ya's hands, and the color and quality were obviously much stronger than the old blacksmith's workmanship, but Lu Ya was not very satisfied with this result.

"Can you show me?" asked the Iron Old Man with some excitement as Ruya asked.

"Uh, yes," Ruya looked at the old man of iron who had left him speechless, and handed him one of the 'spearheads'.

"This, this, this is simply incredible, how did you come up with this method to make iron, its hardness is higher than the weapons we use now, but it still can't solve the problem of iron products being too brittle like human beings" The old man first showed a trace of respect for Lu Ya to think of this method to make iron, and even used honorifics like 'you', but then showed a trace of regret.

"Oh, have you ever seen an iron tool made by a human?" said Ruya, somewhat surprised.

"Hmph, I went to a human city with my master back then, where I learned the art of ironmaking," the old man raised his chin proudly, but then his eyes dimmed a little.

"It's just that human beings are very resistant to our people, and they won't let us get in touch with the true refining essence at all, and in the end, we can only learn my refining skills. After the old man finished speaking, he was a little lonely.

"You also call it skill, I guess people are teasing you, you can boil the molten iron out in that way, it can only be attributed to your luck and biceps" Of course, Lu Ya can only say it in his heart, otherwise maybe this iron old man will not be able to come up in one breath and draw it directly.

"Then look at this dagger," Ruya handed him the dagger.

"Hiss~ This is definitely an iron tool that can only be made by humans, no, it should be called steel, this is a relatively sophisticated building technology even in human society, I have only seen it in human shops before, this kind of weapon generally does not flow into the hands of our orcs, where did you get it" The old man of iron looked like he was stroking his lover and gently rubbed this dagger with his hand.

"Steel, isn't it?" said Ruya, picking up the spearhead in his hand, and after a crisp "ding" of the knife in his hand, followed by a heart-rending howl.

"Ah~ What are you doing, you, you, you actually have such a precious dagger to cut this iron lump, are you crazy, look at the gaps on this blade, tyrannical things, tyrannical things~~" The old man looked at him angrily with the dagger that was knocked out by Luya.

"Cough~cough~ What kind of tyrannical thing is this uncle, it's not like that" Lu Ya said embarrassedly.

"Why don't you count, don't you make one, I'll see. The old man said excitedly.

"Don't tell me, I might be able to make a weapon of better quality than this dagger," Ruya looked omnipotent.

"Hmph~ So what, then you can ・・・・・・ what you say! The old man suddenly put his arm around Lu Ya's shoulders and said excitedly.

Looking at the dagger less than a centimeter away from his face, Lu Ya could only nod lightly, not daring to speak again, for fear that the old man would disfigure himself in excitement.

"Hurry up~ come and take a look" The old man's eyes were red, and he pulled Lu Ya and didn't let go.

"Well, I'll have to make another stove for that method, but it will take a few days to get it done, but there's another easiest way to get to the level of this dagger, or even better than it, but it's a little tiring. Lu Yaliu thought about it and said.

"Well, you still need a stove, for a few days? Then you use your simple method first, don't be afraid of being tired, I still have a lot of strength, old man." As he spoke, the old man patted his chest vigorously, indicating that his sword was not old.

"Well, do you have a hammer or a felt?" Ruya asked.

"There is a hammer, what is iron felt?" the old man looked puzzled.

"I'll go, I didn't even have iron felt, and I said that I would strike iron・・・・・"

Lu Ya, who deeply felt that he was poor, white and stupid, could only start from scratch, and it took a morning to melt hundreds of catties of iron ore before pouring an iron felt, a hammer and a pair of tongs on the spot.

"Hey~ It's all pig iron to make do with it first, and then build a small converter should be no problem, as the saying goes, there are three hardships in the industry since ancient times, supporting boats, striking iron, grinding tofu, I can't come to this iron. ”

Under the strong suggestion of the old man of the iron, Lu Ya handed the hammer into his hand, and briefly repeated the steps of striking iron, the old man threw a spearhead into his own furnace, Xiong Er held a bellows to assist on the side, and after a while the spearhead became red, Lu Ya asked him to remove the spearhead with tongs and put it on the iron felt and began to hammer it hard, and the sound of sparks splashing "Ding Bell Ding Ding..."
