Jia Yi returned to the Chamber of Commerce with the steward carrying the long pole: "You prepare a quiet room for me, and I will sort out these materials." ”

The room in Jia Yijue's hotel is not quiet enough, the last time I made the incendiary bomb to kill it, it was almost disturbed and spilled, this time the time is more urgent, the ship is about to leave, and it is the right way to find a quiet place to deal with it quickly.

"All right!" replied the steward, "but what are you doing with such a long stick?"

"Oh, this is what I use to make a fishing rod. Isn't it going to take a boat, I'm afraid of boredom. Kaichi said.

The steward glanced at Jia Yi strangely: "Do you still have to make the fishing rod yourself? We are a chamber of commerce, although we don't sell fishing rods, but our partners do sell them, wouldn't it be good to just ask for one, it's much better than yours, right?"

Jia Yi was silent, what should he say, saying that he forgot? He is still not used to being the CTO of a large chamber of commerce, and when he was learning art, he mostly did it himself.

"Then I'll give you this, please prepare me a fishing rod. With that, he pushed the steward out of the door and closed it.

This steward doesn't have any eyesight at all, how can he say it so clearly, he should say that he has a fishing rod and give it to you, so it's much more tactful.

"Well, that's my office room, and your ashram isn't ready yet. The steward outside the door said, leaning on a pole.

I'm going to go.,This tsundere.,Jia Yi feels like he's lost in face.,If it's a little beauty, this will make people feel cute, but what is a big man?

Perverted?

This awkward scene skips.

Kaichi entered the room prepared by the steward, it was a vacant room, and there was a lot of miscellaneous items in it, but now it was vacated.

Jia Yiping stepped back from the others, sat down at the table, and opened the package.

Inside was a faded and yellowed notebook, still made of parchment, with nothing on the cover, but it was already a little moth-eaten, and it didn't look very well preserved.

I guess I haven't turned it over for a long time, but the handwriting is still clear and undamaged.

In fact, Jia can write it down once he reads it, his memory is amazing, and when he broke through to become a mage, he also built an index in his mind, and he can quickly consult the information in his mind.

However, he was afraid of scaring others at the time, and he didn't plan to expose his specialty, so that he could steal a lot of information.

If Zhou Bo informed Huang Yaoshi's wife that he would never forget it, then how could the "Nine Yin True Scripture" be written down by her.

So you have to sneak into the village, don't shoot the gun!

This notebook is probably the one taken by the old Ferwood at that time, and the records on it about the dwarven forging process are not systematic, and there are many things to see and hear about it in addition to striking iron.

Old Ferwood met his master at Forge, in the west of the Empire, which produces high-quality ore, so there are the most blacksmiths there, and it also attracts some dwarves to settle there. It was there that Old Felwood met his dwarven master and learned the craft of blacksmithing.

Old Felwood was gifted, short and strong, and the whole was short and tight, which was more in line with the aesthetics of a dwarf, so he was loved by his master and was able to study in his master's blacksmith's shop.

The quality of the dwarves' weapons is due to their special method of striking iron, which is called the uninterrupted striking method. When a hammer falls, it quickly rises with the help of the countershock force of the hammer to the material, and continues to fall the hammer at a high place, and then goes up with the help of the countershock.

The longer it can last, the better the quality of the steel hit.

But this method is not for everyone to learn, ordinary people have a hard time picking up the hammer, and they need to take a breath to lift the hammer again, let alone directly pick up the hammer again with the help of a countershock. Even if it is barely done, it will not last three or five strokes at all, and it will not work at all.

It can only be done by dwarves with their racial talents, plus they are short and strong, waving two unicorn arms.

After understanding this method, Kaichi finally understood why the elder Feywood couldn't learn, even after being single for decades. And his grandfather, Felwood Sr., was able to learn, and he really deserved to be talented.

However, it is estimated that there is also a reason for the dwarves to teach them by hand.

It can be seen from his notes that although he is literate, he must not be very knowledgeable. He wrote down the process of learning art in his diary, but he did not sort it out, and many places were not very clear.

And between the lines, there is also a message, the dwarf has a set of strength training methods, he learned through special methods, but I don't know why it was not recorded, and it seems that his descendants did not learn it either.

In addition to the dwarven iron-striking method, several special processes are also recorded in it, mainly rust-proof. There is a surface coating to prevent rust, as well as a surface passivation process to prevent rust, and several special paints, which are also used to apply rust prevention.

It is said that the dwarven mine can be dug very deep, and the inside is dark and damp, and if there is no anti-rust process, then the iron utensils on the body will easily rust.

Jiayi focused on the first two anti-rust methods, the plating anti-rust is to use a special solvent, dissolve the plating material in it, and then put the finished iron products in it, the iron on the surface of the article will react with the solvent, and the melted plating material in the solvent will be replaced and attached to the surface of the iron products.

This is a bit like the displacement reaction that Jiayi once learned, where the iron is replaced with copper from the copper sulfate solution. But Kaichi wasn't sure if it was just a form or if it was.

This solvent is made by using sulfur and flame stone, which are first calcined into a powder and then added to the acid in the stomach of the flame bird.

Sulfur and flame stones are simple, but the gastric juice of the flame bird is not easy to obtain, it is not that the flame bird is scarce, but the flame bird does not have it here, and there is no gastric juice for the flame bird.

Although this solution can dissolve most metals, only a few can form coatings with iron, such as gold, copper, and red lead stone, among which red lead stone is a plating material that can generate anti-rust coatings.

The surface of the iron made in this way has a layer of bright plating, which is very hard, wear-resistant, and not easy to fall off, and the light can be seen, plus the most important anti-rust is indeed a very amazing technology.

It's just that the cost is not small.

But there is a downside to this method, which is that it is too shiny. Although this looks very stylish, it is not concealed at all, especially in the pit of the black hole, if you encounter an underground demonic beast, it is simply a live target.

And the plating is only the plating after all, no matter how hard it is, it is too thin, and the plating is easy to wear out after a long time, and this kind of wear and tear is more prone to rust.

Therefore, later the dwarves had a second method of rust prevention, that is, the passivation method. A special acid is used to wash the surface of the iron, and the treated surface of the iron is dull and dull, and a special protective film is formed to increase the anti-rust function.

Although the protective film produced by this method is not as durable as the coating, it is easy to deal with, and even if the protective film is damaged, the damaged area is less prone to rust. Moreover, it is also very convenient to re-polish, and the cost is much less than the plating method.

It's just a pity that the second method note is vague, there is only a general direction, and there is no plating method to explain clearly.

That's why old Feywood only mastered the method of plating.
