The swords were packed and sent to Jinling City as soon as possible, and these lobster armors were also sent over, especially those armors used for experiments.

This is a powerful weapon, compared to the weapon used before, it is simply the same as the comparison between the ordinary sword and the cadre Mo Ye in ancient times.

And in this Ying Yun's opinion, now that others are still using ordinary swords, or even those stone beast bone weapons, their own side has already begun to mass-produce the cadre Mo Ye, how powerful is this.

Divine weapons, it's exciting to think about, but this kind of exciting thing is everywhere now, but in ten days, the entire workshop is full of this kind of weapon.

Now the spirit of the craftsmen who do things in these workshops is different, originally they were just some craftsmen sent here, basically belonging to a group of people at the bottom of Jinling City, but now?

The weapons they created took even the best craftsmen in Jinling City a long time to forge.

And here you only need to cast and shape, and then you can directly forge these things further.

And these craftsmen are currently gathered together, still looking at the bucket in front of them with excitement.

This bucket is actually used for cooling, mainly to cool these steel knives that have just been forged red, and now the quenching and tempering process proposed by Li Hang has made many craftsmen frown.

Quenching is already the highest process in this era, at least in the eyes of these people, this quenching is already quite good, and now it is necessary to add a tempering process, which ...... How to control the temperature, how to return, and how long to heat.

It's all their problem.

However, it is certain that this knife that is tempered after urging is better than the weapon that was just quenched before!

In the past, they were the most unpopular craftsmen in Jinling City, and they were sent here mainly to make horseshoes and stirrups, two things that had almost no technical skills. And these two things did not choose to use iron, but chose to make bronze.

After all, the strength of bronze is about the same, and iron is more expensive than bronze.

And now looking at these blades, they are all crying with joy one by one.

Without him, he finally surpassed the old masters in Jinling City.

Although the process is also very crude, but with the help of this steel-making furnace, they temporarily produced very hard steel. It's pretty good to make blades.

Li Hang was not dissatisfied with these excited craftsmen, but it seemed that they lacked some initiative.

Although this is quite good now, this kind of idea that it is good not to make mistakes is really painful.

"Several!" Waving to these craftsmen, Li Hang sat down on the edge of the fire they usually baked on a big grin.

A few craftsmen, you look at me, I look at you, and they immediately walked over. "Li Shangzao! I don't know what to command. ”

"I don't have any orders, but I have one request! When you make these swords, you need to rely on the quality, of course, the more stable the recipe, the better, but if you are mass-producing second-hand farm tools, I suggest that when you make this steel, consider adding some other stones to it, recording the number and type of stones added, and recording the changes that occur in the steel that comes out of the furnace. Li Hang said slowly.

There are countless kinds of special steels in this world, and these special steels are mainly used to make all kinds of special things, such as ships, such as other things.

It is the influence of this trace element on steel that will give rise to various types of steel, such as high-hardness high-manganese steel, and countless other alloys.

A few masters, look at me, I look at you, no one has ever heard of this! Isn't this similar to the Taoist priest who made alchemy?

Looking at their confused eyes, Li Hang explained. "Ladies and gentlemen, there are always some subtle differences in the blades forged from iron ore in different places, no matter how your skills are the same, there will always be a slight difference between them, and we will always say where the iron is good, but the key is to figure out what causes this difference between good and bad, so I let you try this is the reason, add some other things, and see what has an effect on these steels!"

As soon as they said this, the blacksmiths immediately understood.

After all, the scale of smelting in this year is not very large, an iron ore can be smelted for a long time, not to mention, but also can maintain a fairly sufficient output, so as to lay the foundation for the experiment, as long as there are achievements in geological exploration in the future, they can be combined with each other, and analyze what is mixed into it to play a role.

At least it won't be like a headless fly anymore.

"You're saying let's try it, if we don't make it into farming tools or parts?"

"Hmm!"

Although the steel farm tools, tools, and parts are a bit wasteful, if you do this, you can find better materials, and you can even record all these things in the future, not to mention the world, and you can directly enter Li Hang's library.

Although there are no more than 100 books in it so far, the craftsmen are very excited just to see the classification.

Because it's so detailed.

Not only geography or anything, but even those prospecting, smelting, and forging have separate classifications, and even a few days ago, Li Hang took the time to draw weapon drawings for some of their forged swords, shields, and armor.

In the eyes of Li Hang, a modern person, these actions were necessary to standardize production at that time.

But in the eyes of this group of craftsmen, this Nima is the standard of a proper corporal Lixian.

A few other readers have done this.

So a few craftsmen nodded along with the total.

Anyway, this matter is like this for the time being, it is better to listen to Li Hang, anyway, if anything is added, in their opinion, there should be no change.

After all, compared to a furnace of steel, throwing in a few pieces of other ore, this is nothing to them.

But since Li Hang asked for it, they could only find it.

When the boat sailed back, Ying Yun rushed over. He met a lot of people on the road, and they were all looking for him. And now he is holding a lot of silk cloth in his hand.

"Li Hang, Li Hang, look at what I got!" The kid rushed over with an excited face, and the silk cloth in his hand was densely covered with palm prints one by one, and there was only a line of big characters on the silk cloth.

Ask Li Shangzao to open a school to teach.

A few simple big characters, against the backdrop of these hundreds of palm prints, have become extremely unusual.
