Wang Buxing took Zhang Buyi to the next door.

The next door is very large, divided into many courtyards, guarded by the forbidden army, and it is the only place in the entire Han Kingdom that is equal to the royal palace in terms of guard level.

In some ways, it is even more protected than the royal palace.

At the very least, ministers of the rank can enter and exit the palace, but not here.

Everyone who enters here must get the consent of the king.

So even if it was Zhang Liang and Xiao He, they had only come twice under the leadership of Wang Buxing.

It is precisely because Wang Buxing has such an important attitude towards this unnamed next door that many people began to complain, worried that King Han would do the right thing to engage in those side ways.

But as a founding monarch, the prestige is definitely the highest in the whole country, and it is basically difficult for latecomers to catch up.

The king's decision not to be hungry was something that no one dared to stop at this time.

"Your Majesty, we have succeeded...... "As soon as Wang Bu was hungry and entered with his front foot, Ding Lian, the person in charge of the armory workshop, ran over with excitement on his face, and carried a long sword that already had a lot of gaps and was slightly curled.

Wang Buyu carefully glanced at the long sword in Ding Lian's hand.

"How's it going?"

"Look, your lord, this is the result of a hundred slashes with ten bronze swords." Ding Lian handed over the iron sword in his hand.

"Go see those ten bronze swords!" Wang Bu was hungry and said directly.

The sword had already been swept before, so there was no need to look at it carefully.

There are gaps, and there are some curling toughness, but on the whole, it does not affect the use, but it only affects the sense of experience.

The last thing you need on the battlefield is a sense of experience, especially at this time.

Soon, Wang Buyu came to the side of a pile of bronze swords.

Compared with the iron sword, the end of the bronze sword is more miserable.

There were deep gaps, and even a few of them were directly broken into two sections.

Sharpening iron like mud or something is just an adjective, and at this level, the long sword in Ding Lian's hand can also be called sharpened like clay.

The ten bronze swords that were cut could not be used, and three or four were broken, and although they had an impact, they could barely continue to use them.

Isn't this sharpening iron like clay?

"How is this sword made?" Wang Bu asked hurriedly.

Now he is most concerned about whether it can be mass-produced.

If you can't batch it, what's the use of asking for these swords?

"Hehe, Your Majesty, in addition to the method you gave, we have used a new way of thinking, and the yield is definitely considerable." Ding Lian smiled, thinking about his discovery, he felt awesome, a proper great credit.

However, in front of Wang Buxing, he still had to be leisurely, and hurriedly said: "Even if coke and toner are used, although the efficiency of refining steel has increased, if all steel is used, the output will still not be able to keep up." So when we forge, we use steel for the blade and iron for the blade, so that the steel, which was originally only enough to make one sword, can now be forged into three iron swords, and there is no problem in using it......"

Ding Lian Balabala said.

The more Wang Bu was hungry, the more he listened, the more he felt that something was wrong.

Isn't this the traditional steel-clad technology?

The ancient method of clad steel is to put the two together to heat, take them out for forging when they are red, and constantly heat and forge, and finally connect them into one.

If you look closely, you can still see the connection.

This method is indeed very material-efficient, but it is too labor-intensive.

How long does it take for a sword to go from the beginning to the time it can be used at the factory?

Start in ten days, no cap.

It really takes half an hour to heat up, and you can only knock it out dozens of times before you throw it back to continue heating.

Although the subsequent heating will be faster, it basically keeps the rhythm of beating dozens of times and throwing it back to heat for a quarter of an hour.

Not to mention tens of thousands of strokes of a sword, at least thousands of times of forging can barely be used.

Wang Bu was slightly disappointed.

Although Ding Lian improved the forging efficiency of steel according to his own requirements, he even used steel-clad technology to save materials.

However, this ancient method still cannot meet the requirements of mass manufacturing in a short time.

If you want to arm the 50,000 cavalry on the front line within half a year, you must recruit at least 3,000 craftsmen.

Those who can strike iron this year are all high-level technical jobs, which are too difficult to find.

So, if you want to be more efficient, you have to think of other ways.

"Go find a place outside the city near the water and fence it off!" Wang Buxing thought about it for a while, and ordered directly to Zhang Buyi.

Separating iron from iron ore is also an important step.

Once this step is done, the number of subsequent forges can be reduced.

Moreover, in the process of iron smelting, too many harmful impurities are not removed, and can only be removed by continuous forging.

Some of them can be solved by refining molten iron in this process.

The blast furnace iron-making king is not hungry, and he also knows the general things.

But if you ask specifically, you will be blind.

Originally, I hoped that Ding Lian and them would be able to make a name for themselves, and they were guiding themselves, but they didn't expect that they only focused on the quality of weapons, and didn't care about the steps of ironmaking at all.

When Wang Bu returned to the palace, he began to use his leisure time to write and paint, and there were many things to do.

It is unknown whether the blast furnace can be used for the time being, but how to improve the efficiency of forging, there is a way for this king not to be hungry.

Luoyang is surrounded by water, and it is not difficult to find such a place.

In the early morning of the next day, Wang Buyi asked Zhang Buyi to find someone to dig a large ditch out, the place near the river should be larger, and the internal passage began to narrow.

There is no need to dig up the junction for the time being.

Just dig a ditch, you don't need to dig too deep, a depth of one or two meters is enough.

So Zhang Buyi directly mobilized 500 forbidden troops to dig in person.

Anyway, it doesn't take too long a distance, and it adds up to more than 100 meters in total.

In just one day, the forbidden army dug the channel as required, except for the two ends that were not opened, the rest were done according to the requirements.

Early in the morning of the third day, Wang Bu came here with a group of people.

Coming to the channel that had been dug, Wang Buxing felt about a place, stretched out his hand, and the craftsmen began to get busy.

"Your Majesty, what is this for?" Zhang Buyi looked at the busy craftsman with a confused expression, as if he had suddenly become a fool, and he couldn't understand anything.

"You'll know when the time comes!" Wang Buyu smiled mysteriously.

The craftsman first went down to look at it, then lifted the stone hammer and began to harden it on the ground.

After a while, the soil layer was almost hardened, and it began to be covered with smoother stones, especially the middle point, which was specially treated.

Of course, it doesn't take much effort, it's just a little more special.

After that, several planks are put together through a gap reserved above, and in the middle is a tall stake, high and raised.

A shelf was also erected at both ends of the canal to support it, and at the very top of it, there was a horizontal device that protruded about half a meter or so.

Referring to the principle of the wheel, plus the shaft scheme given by Wang Buxing.

The craftsman created a simple model out of wood, and in the middle of the protrusion is an I-shaped device that uses the principle of levers to carry out the work.

After a lot of work, a simple experimental setup was completed.

The time is tight, the task is tight, and it is unrealistic to want to do it once and for all.

The significance of this is to test whether this principle is reliable and feasible.

So what you carry below is a stone that weighs only ten pounds, and there is no chassis, so you can just smash it on the ground.

Soon, the installation was completed and the two ends of the aqueduct were opened.

A large amount of water began to pour in, and the water level gradually rose.

The wooden wheel, which had been immersed in the water, began to rotate slowly under the pressure of the water.

With the increase of digital digits and the increase of water pressure, the speed of the wooden wheel has also begun to increase.

And the ten pounds or so stone also began to hit the ground fiercely and regularly.

Seeing this scene, Wang Bu was hungry and smiled.

Pointing to the stone that looked like a pile driver, he said, "Using him instead of manpower forging, do you think the efficiency of building weapons will be improved?" ”

Zhang Buyi looked at Wang Buyi with some dementia, and then looked at the pile driver that was still working.

Then I remembered the process of building weapons.

If this thing is smashed down, the strength must be greater than that of manpower.

Don't say much, if it smashes it, it can at least block people from smashing twice, right?

And this thing won't get tired, it will keep smashing at this frequency.

In other words, as long as the preheating of the iron can keep up, a craftsman can forge weapons without stopping.

"Wang ...... Your Majesty, you ...... You're really ......"

Zhang Buyi looked at Wang Buyi in shock, and he didn't know what words to use to describe Wang Buxing's wisdom.

However, the good times were short-lived.

It seems to be to resolve Zhang Buyi's embarrassment.

I only heard a click, and the water wheel continued to rotate, and the frequency continued to increase.

But the stone stopped swinging up and down.

Looking at the sudden strike device, the foreheads of several craftsmen were instantly covered with cold sweat, and while carefully looking at Wang Buying, they quietly checked the problem.

After some inspection, the craftsman finally found the problem, but still said cautiously: "Your Majesty, it is the wooden hinge that is broken, and the wooden one is not used, if it is commonly used, I ...... I think I'm going to have to make this out of iron or steel. ”

Seeing the frightened craftsmen, Wang Bu was hungry and wanted to laugh but couldn't.

It's all wood, don't you know if you use it or not?

Although their image on the outside is enlightened enough, in front of these craftsmen, after something goes wrong, they are still worried that they will be punished for it.

So, Wang Buxing looked at everyone with a relaxed face, and said: "Today's success or failure is not important, the important thing is to verify whether this method is feasible, every detail of this device, you must write it down, use iron where iron should be used, use steel where steel should be used, and use steel where steel should be used, and you will be responsible for coordinating this matter and building it as soon as possible......
