When Ruya returned to the tribe, he hurriedly ate something and went back to his room and fell asleep, until the next day, near noon, when he stretched out comfortably and got up from the bed.

After a brief wash, Lu Ya first went to look at the captives who were locked together in a large wooden cage, and found that they were gnawing on some half-baked beasts, and there was nothing wrong with their emotions, so he went to say hello to the old patriarch first. The old patriarch, who had already learned the details of this operation from Bai Lifu and them, did not ask Lu Ya much, but only looked at Lu Ya with a trace of hesitation in his eyes, but in the end, the old patriarch only encouraged Lu Ya and asked Lu Ya when he would go to Juli City.

"Patriarch Grandpa, can't you be promoted to become a real priest if you don't go to Juli City?" Lu Ya wondered.

"That's not really, mainly because after passing the test of the priest's tower there, you can get your own corresponding identification, just like this," the old patriarch finished speaking, and took out a milky white round badge from his bosom.

As a result, after the badge, Ruya took a closer look and found that there was nothing peculiar except for the somewhat strange pattern.

"What's the use of this thing," Ruya said, returning the guild leader to the old patriarch.

"Hehe, he doesn't have any effect on his strength, but he is a status symbol in the orc clan, such as not being able to be enslaved, and being exempt from paying the city entrance fee, of course, there are not only these two, you will gradually know in the future" The old patriarch explained slowly.

"I know the patriarch grandpa, I want to wait until this winter is over before I go"

・・・・・・

After Lu Ya came out of the old patriarch, he came to the door of the only iron old man in the tribe, this old man is similar to the old patriarch, he used to be a blacksmith in the tribe, and he can usually repair damaged weapons and farm tools, and then after a long time, I don't know who called it first, 'Iron Old Man' became a nickname for him, but he himself has no opinion on this, but he is quite happy, and over time, everyone calls him 'Iron Old Man' As for the original name, it is estimated that even he himself has forgotten.

It's just that in recent years, as he gets older, he has gradually become idle. At this moment, the old man was lying on a rocking chair leisurely, and when he heard Lu Ya's request, the old man agreed excitedly, and then used the iron ore provided by Lu Ya to demonstrate the ironmaking technology he had mastered.

It's just that everything that followed really made Ruya stunned. The old man first dragged him to a dusty stove at the back of the house, then threw a few pieces of iron ore and firewood into it, and then led the firewood, and finally found a simple blower skin that leaked everywhere and began to blow air into the furnace after a burst of drumming.

Time passed little by little, and the old man did not know how many times he filled it with firewood, and only when Ruya was about to fall asleep did he exclaim, "Okay." Then he opened the tap hole with his still trembling hands, only to see some dark red viscous molten iron full of impurities slowly flowing into a finished model, and after cooling for a while, the old man found a stone and smashed it at the model.

Seeing his head move, the corners of Lu Ya's mouth couldn't help twitching, and the old man threw this black thing into the water with an excited face, "Ah~~"

A mist rose, and after a while, the old man walked up to Lu Ya with his masterpiece and handed it to him.

"Finished?" asked Ruya, somewhat uncertain.

"It's over, you see that this spearhead is a good spear when it is slightly polished, I didn't expect that I haven't done it for many years, and it is still not inferior to my level when I shot again."

The old man was obviously very satisfied with his performance today, and praised his work vigorously.

"Excuse me, where did you learn this technique," Ruya interrupted, still looking intoxicated.

"This is what I spent a long time learning from my master back then, and this set of iron-making equipment was also left to me by my master, and my master praised me for surpassing his level back then, I didn't blow back then, I ・・・・・"

"Okay, don't say it, I know, thank you so much, I'll leave first if I have something to do" Lu Ya really couldn't listen to it, grabbed the black spearhead and ran away without a trace.

"Hey~ I haven't finished talking yet, if it weren't for the fact that you are a priest, I wouldn't show it to others・・・・・" The old man was very angry that Lu Ya ran away without listening to his glorious deeds back then, and he muttered in place for a long time before continuing to return to the rocking chair in front of the house and walked down.

・・・・・・・

Sitting on the bed, Lu Ya looked at the so-called 'spearhead' in his hand and became a little distracted.

The whole "spearhead" is grayish-black, and the surface is covered with small pits, and the slag magazines visible to the naked eye are mixed in it, which gives people a rough and even prickly feeling when touched. Blacksmith's craftsmanship, Lu Ya began to doubt the physical rules of this world, not to mention the quality of the finished product, the old man actually succeeded in melting the iron ore with such a simple broken furnace and tools, which was too incredible in Lu Ya's opinion, but thinking about the old man's effort, Lu Ya could only attribute this to his long and hard work. In addition, Ruya thinks that the oxygen content of the air in this world may be much higher than that of the earth.

Lu Ya did not learn how to smelt metal in detail, but he often read some time through novels, he can still roughly understand how to smelt iron ore to get relatively pure molten iron, as for how to smelt it into harder steel after getting molten iron, Lu Ya only knows a rough idea, and then he still needs continuous experiments to succeed. It's just that he wanted to learn from the ironmaking experience here, and he has completely abandoned this idea at this time.

"No wonder I didn't see a few weapons in the whole market, no wonder the iron products are so expensive, it turns out that their smelting water products are so low, so the smelting water products on the human side are much stronger than the orcs, and the technology is so tightly blocked, ordinary orcs can't use that kind of good iron products at all, no wonder the spears and other weapons I've seen are tinged with a burst of cyan, it seems that the entire orc society is still basically in the bronze age." The more Lu Ya thought about it, the more he felt that this was the case, and then his face gradually became excited.

"Business opportunities!money!Monopoly!Quack, if I can make iron tools that are as high as those of human beings, or even better than that, then why worry about a happy life coming too slowly, uh~ No, the truth that the husband is not guilty and guilty is the same everywhere, or quietly enter the village, don't shoot a gun, hehe..." The corners of Lu Ya's mouth couldn't help but hook up a cheap smile.

In the next few days, Lu Ya found Xiong Da and Xiong Er, and the three of them played 'mud' together.

In one corner of the tribe, there were several cracked or rotten piles of mud everywhere, these were the earthen blast furnaces of Lua's failed experiments.

"It should be okay this time," Ruya muttered as he grabbed a pile of yellow-red mud. These are not the local mud that Rua used to use, but the clay used by the tribe to make clay pots.

The next day, when the newly built furnace was almost dry, Luya lit the fire again, and this time it went well, and the clay and stone blast furnace was still intact after several hours of cauterization, barely meeting Luya's requirements.

Of course, there can be no ready-made blower, so Lu Ya can only build one by himself.

Limited by limited resources, Luya could only choose the simplest blower equipment he knew, the wooden bellows. The manufacturing principle of this bellows is very simple, and Lu Ya has seen some rural fires and cooking using this kind of air blast equipment before crossing.

This kind of bellows as a whole looks like a big rectangular box, a lever is revealed from the outside of the bellows, the part that is exposed is made into a handle, the lever is connected to the partition inside, the bellows has two air outlets on the front and cover a movable wooden board respectively, when the partition is pushed to blow outward, this partition will be blown up and does not hinder the air outlet, when the partition is pulled to inhale, this board will fall down to block the inhalation from here, and the countercurrent wind will blow out from another air outlet on the upper side and there are two one-way air intake valves inside, in short, whether it is pushing and pulling can blow out the air, it is the simplest blowing equipment that Luya can make at presentLuya felt that he couldn't build it with the resources he had at hand now.

found the carpenter who is known as the best craftsman in the tribe, and under Luya's detailed description, the carpenter finally did not disappoint Ruya like the blacksmith, and it only took half a day to successfully make a wooden bellows.
