"The Holy One has arrived."

Hearing the familiar shouting, Gao Xiaochuan jumped three feet high in shock, and then rushed out of the war bureau with a roll.

But in my heart, I was terrified, I came two days ago, why did I come again today?

Being an emperor is really idle, but even if you are idle, what are you doing in such a rotten place? Is wood not fun, or is the woman in the palace not fun?

Under the leadership of Gao Xiaochuan, as soon as Tianqi stepped into the gate of the military battle, he saw hundreds of figures kneeling on the ground, so he frowned and said: "Next time, don't let the craftsmen put down what they are doing, just do things well." ”

"Yes, hooray." Gao Xiaochuan hurriedly agreed.

The heavens enlightened for a moment, Gao Xiaochuan understood, and immediately said to the craftsmen: "Long live the compassion, next time you don't have to drive, get up, go to work." ”

After everyone got up cautiously, they immediately returned to their respective stations, and the huge battle bureau sounded the sound of clanging again.

"You send to the Powder Office to get the best twenty craftsmen." Apocalypse instructed Gao Xiaochuan again.

Gao Xiaochuan's heart moved, couldn't it be that he invented better gunpowder again? He didn't dare to delay, and hurriedly sent a young eunuch to carry out the order.

Apocalypse didn't look for a cool place to stay, but walked slowly towards the inside of the military battle bureau, Gao Xiaochuan was startled, and hurriedly said: "Long live, it's stuffy inside, and the smell is unpleasant......"

"Yes, hooray, the dragon body matters." Wang Tiqian also persuaded, and he didn't want to enter such a dirty place in his heart.

Apocalypse waved his hand casually and said, "It's okay." ”

Wang Tiqian had no choice but to persuade again.

Gao Xiaochuan was also very helpless, the biggest person he had dealt with before was the former palm seal eunuch of the War Bureau, so he didn't know how to deal with the great tomorrow at all, so he could only follow carefully.

In fact, not only him, but everyone in the entire War Bureau, including the craftsmen who were working, also quietly kept an eye on it, for fear that they would accidentally offend Long Yan.

When someone saw the apocalypse coming, they instinctively wanted to kneel to greet him, but they were immediately stopped by the apocalypse waving his hand, Gao Xiaochuan understood, and when he saw someone absent-minded, he scolded him for working hard and not having to kneel.

As it continued to go deeper, the unpleasant smell mixed with sweat, molten iron, wood, charcoal, etc., became more and more intense, which was simply disgusting, not to mention the Ninety-Five Venerable like the Apocalypse.

However, his soul comes from another world and is not so high, so even if there is some discomfort, he tries to hold back.

Gao Xiaochuan on the side endured even more uncomfortable, because he rarely entered inside, and even if he occasionally came in to inspect it, he covered his mouth and nose with a handkerchief.

Not to mention Wang Tiqian, he almost vomited a few times, but fortunately he tried to endure it.

But now even the apocalypse is not so hypocritical, do they dare to do this?

"Ding-dong, ding-dong......"

The apocalypse walked in the direction where the voice came, and after crossing a threshold, it suddenly opened up, and a wave of heat also rushed to the face, and sweat was about to burst out of the pores.

Here and outside are two worlds, one hot as a furnace and the other as cold.

"Hooray, watch out for the dragon." Gao Xiaochuan had the courage to remind him, for fear that the emperor would have something wrong with his military battle, in that case, even if he had ten heads, it would not be enough to cut off.

"It doesn't matter."

With that, Apocalypse walked directly to the nearest iron-making furnace, where two craftsmen who had stripped off their shirts were sweating and pounding a piece of red-hot iron.

Their expressions were focused, and coupled with the noise around them, they didn't even notice the approach of Apocalypse and his party for a while.

Until the man who wielded the sledgehammer was about to smash it down, he inadvertently glanced at the corner of his eye, and suddenly his face changed, and his hand was loosened, and he almost let the hammer fall and hit himself, because he didn't expect the emperor to come to such a place.

Before the apocalypse could stop him, he dropped his hammer and fell to his knees.

The other man was startled, and in a panic his hand loosened, and the pliers holding the iron fell off, and even the red-hot iron fell from the anvil, almost burning his own feet.

Gao Xiaochuan hurriedly said: "Don't kneel, don't kneel, get up and do your business." ”

In case such a thing happens again, the apocalypse immediately asked a few eunuchs and the Han general who followed behind him to inform the others not to bow down and do things with peace of mind.

The two craftsmen stood up nervously, and then resumed their work, but although they were still working hard, the rhythm of striking iron was clearly out of order.

Apocalypse didn't look at them anymore and immediately walked down to the next place, where the two were taking another step: rolling the barrel of the gun.

They put a forged red-hot iron plate on a U-shaped mold, and then hammered the middle part of the iron plate continuously, so that the iron plate will be recessed into the U-shaped model from the middle little by little.

In order to bend the iron plate faster, the hammer surface used is spherical.

However, after the iron plate is taken out of the furnace, it will continue to cool down, and if the temperature is not enough, it will be difficult to hammer, so the craftsman needs to send the iron plate into the furnace from time to time to heat, and then take it out for hammering, and so on.

This is a slow and very physically demanding task, as well as mental energy, because it is necessary to concentrate on turning the position of the iron plate from time to time to adjust its stress surface, otherwise it will be difficult to form, or it will not be able to achieve the desired shape.

With continuous hammering, the iron plate slowly closes, and finally forms a tubular prototype.

But this is only the first step to complete the barrel, if you want to ensure the quality of the barrel, you also need to wrap it with a second layer of iron plate on the outside, which requires repeating the above work again, and finally form a double-layer barrel, the purpose of which is naturally to ensure the safety of the barrel.

The quality of a barrel not only affects the power of the musket, but also affects the life of the soldier, because the inferior barrel may explode at any time.

After the prototype of the tubular shape is created, a round iron rod of uniform thickness is inserted into the iron tube, which plays an important role in determining the caliber of the barrel.

Because the barrel that has just been hammered out will definitely not be the right caliber, so it has to be hammered, heated, hammered, and reheated, and so on.

At this time, the hammering should be changed to a concave hammer, which has the same effect as the U-shaped mold, so that the iron pipe continues to form at the same time, and the traces at the interface close and disappear.

Finally, an ordinary plane hammer is used to shape the appearance of the iron pipe.

The shape of the barrel of this era was not round, as was common in later generations, but octagonal, because the barrel of this shape was easier to fix on the butt.

After the shaping of the iron pipe, you can take out the iron rod inside to cool, this process can not be directly put into cold water, otherwise it is very easy to cause the barrel to deform, in that case, it is difficult to remedy.

After the barrel has cooled, the inner wall is then drilled with a steel drill to smooth and straighten.

This is very demanding on the process, and only about an inch can be drilled every day, so it may take a month just to drill the barrel.

Of course, if you cut corners, it will be a different matter, and now that the apocalypse is personally watching, this will naturally not be allowed to happen.

However, he couldn't keep watching the repetitive and long construction process, and he only had one feeling now: it was too slow, too hard.

This is still he did not know the process of building a complete barrel, otherwise he was afraid that it would collapse directly.

It takes more than a month for a skilled craftsman to produce a musket, and if 10,000 guns are to be mass-produced, then it will take at least a thousand skilled craftsmen a year?

As an emperor with a modern soul, he couldn't accept such efficiency at all, so his first thought was naturally to put on a machine, even if it was a hydraulic machine.

But now that I have no point of invention, and I am not an expert in this field, I can only think of other methods.

At this moment, a figure rushed from not far away, and then knelt on the ground with a thud, kowtowing frantically, while crying: "Long live, please be the master of the villain, be the master of the villain." ”

Seeing this scene, Wang Tiqian was shocked and was about to order his arrest, but was stopped by the apocalypse waving his hand.

Is this what is called a complaint? That's a big risk, and ordinary people will definitely not dare to do this until they are cornered.
