As soon as this private product was bought, Ren Daoyuan was shocked. These are not ordinary fine steel, but actually semi-finished black iron. Black iron is made of meteorite. In meteorite, it contains a lot of impurities. If all these miscellaneous products are removed, it is black iron.

Meteorite is heavier than ordinary stainless steel. After removing impurities, the black iron is at least five times heavier than the steel. A weapon made of black iron is not available to ordinary strong men. It is too heavy.

There are a lot of meteorites sent in from the prison, but they are very messy. All of them need to be cleaned up. First, classify the meteorites, put together the meteorites that have been processed more than once, and a pile of them have been processed.

Next, raise the fire and start the furnace, put the crucible on the stand, and put the meteorite material into it, and activate the fire with all its strength. The melting point of the meteorite is much higher than that of the fine steel. Although it is not as easy as the star stone, it is not so easy to melt.

After melting, you still need to remove impurities, endure the heat of the roasted eyebrows, use an iron spoon to skim the waste floating on the top, and then pass through the golden wire mesh sieve. According to the size of the mesh, you need to pass five sieves in front and back. What you get is purer iron, which is not far from the black iron at this time.

It seems easy, but it is actually a very tiring job. The crucible can only melt less than ten kilograms of material at a time. In order to increase the firepower, the crucible cannot be separated from humans. Therefore, even if Luo Zi sent him two helpers, he could only melt one furnace of material at a time. This furnace will take at least half a day.

In the afternoon, Luo Dajiang came back from work and personally handled the processed molten iron. Although he liked Ren Daoyuan very much, he was more willing to believe in himself in terms of craftsmanship.

When Luo Dajiang came back, it did not mean that Ren Daoyuan could rest. He had to continue melting the furnace, and even turned on another furnace at night. It took about eight or nine hours a day to circle around the furnace. When he returned to his room, he fell asleep and didn't even want to wash his face. He had no energy to check the dreams until dawn.

There was a lot of materials sent in outside. There were three furnaces a day. Ren Daoyuan had been busy for a whole month. He had a layer of skin and finally finished all the meteorites. However, Luo Dajiang, with Ren Dayuan's help, worked very smoothly. He found that the iron handed over from Ren Daoyuan could almost be condensed into very good quality black iron. Even if he asked him to take action personally, the result would not be much better than this.

After a month of fatigue, it does not mean that Ren Dayuan can rest. Luo Dajiang is going to open the furnace. This time, the furnace was two large weapons that needed to be formed in one go. The materials used were the Xuan Iron that was tortured by Ren Daoyuan some time ago.

Of course, what we used this time was not a crucible, but a special furnace called the Weapon Supervision, and put all the refined materials into it at one time, and ordered people to keep adding fire.

Refined black iron is relatively easy to deal with, and there is no need for craftsmen to watch. Just ask the fireman to keep an eye on the fire, and it will take a long time to melt.

In front of the smelting furnace, the fireworks with their own weapons supervisors watched. Ren Daoyuan could not be idle, but followed Luo Dajiang to make molds. This mold making is a necessary craftsman, and it is a craft that requires relatively high requirements for craftsmen.

Usually, mold making uses cheap things such as mud, clay, and sand. These things are everywhere, and as long as you are willing to provide strength, there is almost no cost. However, such materials are only suitable for making rough molds. If you want better ones, you must use wax.

This wax is not a wax used by ordinary people, but green wax. If certain medicines are added to the wax, the wax mold can withstand the heat that ordinary people cannot imagine in a short period of time. Even black iron can not melt it. After the iron is cooled, the wax mold will be broken and the objects obtained can even be as fine as the thickness of the hair. It is currently recognized as the best tool mold.

Everyone knows the benefits of wax molds, but not everyone can afford it and can use them. First of all, the demand for this wax is not ordinary, and wax added with medicine can only be used once, but it will not be used the second time, which will increase the cost of wax molds to a level that most people cannot afford.

Secondly, this wax mold requires fineness, not only skillful craftsmanship, but also several or dozens of carving craftsmen. The larger the wax mold, the more effort it takes to make it, and the higher the requirements for craftsmen.

Luo Dajiang's craftsmanship is naturally fine. Although he is rich, he cannot afford it. Someone sent it in from the prison. He almost took away half of the craftsmen in the weapon supervisor and helped him make molds together. Half-baked guys like Ren Daoyuan can only be used as coolies. When modeling, it is much easier to use than small workers.

When the mold making was later and needed to be meticulously crafted, Ren Daoyuan was driven out, and he was no longer useful at this time.

After several days of work, Ren Daoyuan has seen the trick. These two wax molds, which are one foot thick and are shaped like spherical, should be used to cast a pair of sled hammers.

There are many types of weapons in the Jiuzhou Continent, but standard weapons are mainly swords, swords and guns. This is true for any unit. Only generals choose unique weapons.

As the king of heavy weapons, hammers are naturally not uncommon. However, there are not many good warriors. Hammers do not mean that you can make good things with strength. You must also have corresponding martial arts. The warrior system in Jiuzhou Continent has long been mature, and the top-level human-level people have a thousand pounds of power. Among all the **s, there is no shortage of strong men, but few people use hammers as weapons.

Think about the meteorite material and the large amount of green wax sent, and just calculate it briefly and you will know that the cost is extremely high, and ordinary generals may not be able to afford it.

Ren Daoyuan, who was rushed to see the furnace, went to leisurely for a while after more than a month of high-intensity work. There is no technology for watching the furnace when viewing the fire, as long as the temperature does not fade, it is enough to have those fireworks.

Ren Daoyuan has a very special status in the weapons prison. As a slave, he should have been the lowest group of people, but as a assistant to Luo Dajiang, he has a high degree of freedom. Even the chief Jaycee Chan-seok is too lazy to care about him.

There was nothing to do during the day, Ren Daoyuan wandered around the weapons prison. He could go around at will except for some places with guards.

After a few days, Ren Daoyuan saw several good places. First, there was a material warehouse, where various materials were piled up like mountains. Secondly, there were several warehouses. These warehouses were specially used to store made weapons. There were guards outside, so Ren Daoyuan naturally could not get in.

The more I can't get in, the more itchy I feel. Although most of the weapons here are made of stainless steel, they are nothing. They are mainly ten refined ones, a few of them are hundreds of refined ones, and hundreds of them are treasures, which are rationed to officers at all levels. But after all, the number is huge. Who knows if one or two Taoist fetuses will appear among these weapons?

You should know that Taoist tyre is a natural achievement, and luck is the main reason. When I was in Yanqing Mansion, a chariot of weapons was found like the horizontal sword. Among so many weapons, who said that I could not find a few of them?

With an idea, Ren Daoyuan thought about it. His identity made him unable to enter the arsenal at all, so he could only turn his mind on Luo Dajiang.

"Master, my skills have not increased recently. I want to learn from other people's craftsmanship, but I don't know if it's OK?" Ren Daoyuan asked carefully when he found Master Luo when he was not busy.

"Well... there are some truths... let me think about it." Luo Zi touched his chin and hesitated. After a few months, Ren Daoyuan's craftsmanship increased, but after all, the time was too short and it was still much shorter than his requirements. But he didn't have time to give him a detailed guide, let alone a slave, Luo Zi would not be too concerned.

But the better the craftsmanship of Ren Daoyuan, the more he can help him. Therefore, he is still willing to see Ren Daoyuan study hard. It is difficult to improve quickly. You must know that it is quite easy to get from a small craftsman to a small craftsman, but it is much more difficult to get from a small craftsman to a craftsman. If you want to become a big craftsman, you not only need to be good at learning, have opportunities, and have some guidance, but also need talent.

After a few months of Ren Daoyuan, he was already better than an ordinary little craftsman and could already drive the furnace to make troops. However, at this level, he is still far from the craftsman. As for the craftsman, he should not even think about it. Even if he is very smart and easy to learn, it is impossible without more than ten years of hard work.

"What do you think?" Luo Zi asked. He has been busy making molds recently. The pair of sledgehammers were personally ordered by the general. The general's ability to like his skills has already given him great face. He must show the highest level to satisfy the general. If the general is satisfied, although he cannot improve his identity, he will be superior to several masters in the Iron Supervisor, which is very important to him.

"How do you want to see the process of other craftsmen?" Ren Daoyuan naturally would not say that he wanted to enter the arsenal, but instead took a turn to another way.

Sure enough, Dajiang Luo shook his head repeatedly: "That's not possible. Every craftsman has a lot of work. He also needs to give guidance to the craftsman. If you go there, it will only add trouble to people."

"Then...what should I do?" Ren Daoyuan was secretly happy. He had known that you would be like this. Although those craftsmen were taught by Luo Dajiang, who did not want to work hard and become a craftsmen? He learned many secrets that Luo Zi had not passed on. Although he had swear and had not learned them thoroughly, Luo Zi would never allow him to reveal these things.

"Don't be too anxious." Luo Zi couldn't think of a good idea for a moment. After all, this craft requires time to accumulate, but he also needs an assistant who can help and trust. If Ren Daoyuan's craftsmanship is high enough, he can help a lot this time. In order to make wax molds, he had to teach some skills that he didn't want to teach to a few craftsmen who came to help.
