The ship had almost no cabins, just a hull with a huge sail, and a few places for sailors to stand and paddle around.

At the back of the ship there was a little resting place for them, and the front half and the middle of the ship were almost all piled up with a black thing.

No one knew what it was, but a lot of people were far away.

Many people have seen it and said that it is the soil of hell or something.

Although this kind of legend is not of any use, it has kept many people away from a ship, and even the sailors above are confused, this thing is like a stone, what is the use of it.

Li Hang was very pleased, and hurriedly asked the people in the house to send this boatload of black stone-like things to the workshop.

This is coal, but it has not yet been coking.

And coking is actually similar to those fired bricks.

Ordinary red bricks are actually easy to burn, but green bricks need to be burned in isolation from the air.

The same is true for this kind of coking coal, not to mention that even if it cannot be made into coking coal, these coals can also be made into lotus root coal or other fuels, as a domestic fuel, which is relatively safe to use.

However, Li Hang sent the coal to the workshop, and the craftsmen in the workshop immediately began to make coking coal.

This has been done for a long time. All the theories and infrastructure have been done a long time ago, and even the coal furnace for making coking coal has been done a long time ago.

Although there are no refractory bricks, this coal stove is also intended to be durable, at least in the current position, this thickened coal stove has not had any problems.

The production of these coking coals can be said to be quite convenient, once the production is completed, once it is formed, it can be continuously made of steel.

What are the benefits of steelmaking?

Needless to say, there is no such thing as steel.

The slag alone can be used to make cement, refractory bricks, and many more useful things.

When these things are ready, these refractory bricks can be directly used in their own steelmaking blast furnaces, and then improve the efficiency of steelmaking.

What's more, this kind of steelmaking production can drive other industries, and it can be said that when this steel comes out, there are so many things that can be done.

Any steam engine, the efficiency of digging coal will directly increase, and it can also make bigger and stronger things.

Li Hang's face showed a hint of excitement, because this kind of thing he made at this time was useful! In addition, it is possible to complete the improvement of the base material in this way.

Within three days of the actual coking coal being baked, the craftsmen took the sword made of coal-smelted steel and compared it with the sword made of coking coal-smelted steel, and immediately knew the difference between the two, and the perfect combination of the iron-clad blade and the carburized blade made this new style of knife almost immediately compared all the previous blades.

On the day of the opening of the furnace, Ying Yun was just as nervous as the men waiting for the birth of their children at the door of the obstetrics and gynecology operating room in later generations.

"Li Hang! Can it be done? Ying Yun was a little anxious and spun around in place.

This can't be blamed for not being in a hurry.

Emperor Wu even gave Li Hang a fief, in fact, it was a fight, and everyone was happy, what would happen if he lost? No one knows, it is estimated that it is the kind of fiefdom that has been recovered.

But what about the impact on Win-Yoon?

If you become it, it's the icing on the cake, and if you lose, it's a cheat.

"You've asked five times, the previous samples have been shown to you, and you still compare them with your so-called divine soldiers, you know what the difference is, I don't have any godcraftsman-level craftsmen here, there is only a group of skilled workers here, that is to say, as long as this method can be popularized, the Daying Dynasty can obtain hundreds of such blades, and the previous lobster armor can also be harder!"

The progress of material technology is not such a half-star progress.

The simplest truth.

Before the lobster armor in the Roman era, there was a thing called muscle plate armor, and the bronze muscle plate armor looked good, and it was dressed like a muscular man, but the defense effect was not good, and it was estimated that it was the same as the general's dress at the time, but what about after it arrived?

Before the Napoleonic era, almost all the armor on the heavy cavalry was this kind of overall casting, not to mention the strong defense, and even the casting process was simple.

Just cast it.

Now Li Hang's workshop is the same, almost all of them are cast by this method to make the slats needed for slatted armor.

He even experimentally made a piece of heavy armor.

However, what Li Hang cared about most was the other equipment made by those craftsmen, the general armor made according to the current standard armor of the Great Win Dynasty, but all the parts that were all fine iron were replaced with steel.

Not to mention the great increase in defense, coupled with the integral casting process, the impact on blunt weapons is also much stronger.

It is not an exaggeration to call such armor a treasure armor in the future. The craftsmen had been busy inside for nearly a day, and finally the first batch of swords was pushed out.

Thirty steel knives.

It was an authentic thick-backed broadsword made of steel, and it was used to cut through small weapons that were broken almost with a single slash.

This kind of katana weapon against the Japanese in the War of Resistance Against Japanese Aggression in later generations has an amazing thickness, it can be said that regardless of whether the opponent's weapon is sharp or not, it is easy to get stuck in it, and this itself is made of good steel, and its sharpness is enough to cut some small weapons.

Ying Yun held these weapons, and his eyes began to glow. "Lu Zheng, you come and try it!" After speaking, Lu Zheng on the side pointed at the slatted armor he had made before with a steel knife.

It was heavy armor, and it could be said that it was the best template, because this kind of slatted armor could not be penetrated by many previous weapons.

The guard named Lu Zheng pulled up his sword and whistled lightly. "Good knives!"

Then there was a powerful slash, and a deep knife mark appeared on the lobster armor made of fine iron.

Although he didn't cut in, he cut the strongest armored front.

You know, this is heavy armor.

After picking it up, the edge of the knife did not roll the blade, and then I took out the previous chain mail and some rattan armor and scale armor, and almost all of them were cut with a knife.

It's just a difference in the degree of size.

It can be said that this armor can no longer protect against this weapon.

This is the thickest part of the cut, if according to their technique, there is no problem in cutting the non-thick part, but because this is a display, so they just use brute force, Rao is so effective I also want to be amazing.

What's more important is the effect of these things!

This effect had already suppressed Win Yun, and the blades that followed were exactly the same as this one, with little difference.

The large-scale production that Li Hang said has been realized!
