Time travel rebellion, I'm serious

Some people say that it is like three autumns ago, and this is the feeling that the ordnance in Hetu Mountain now gives Liu Wu.

The changes were so great that he didn't even recognize them anymore.

The original ordnance depot was just an open space. Although there were walls around it, they were only mud walls.

Not only that, even the equipment used to make ordnance, which is what ordinary blacksmiths use, is nothing special.

No, I can't say it's nothing special. At least it has a hydraulic forging hammer, but it's just too heavy and crude.

Now, there are water-powered forging hammers, wind-powered forging hammers, steam-powered forging hammers, water-powered blowers, wind-powered blowers, and automatic grinding wheels.

Wait, wait, wait, there were so many changes that he was overwhelmed.

These are just the ones he knows, and there are many he doesn't know, such as a machine that can pull steel into silk thread.

In Huang Biehe's words, although it is immature and easy to break when drawing, it is uniform in thickness and can be produced in batches and quickly.

Under the leadership of Huang Biehe, Liu Wu visited the wire drawing process and also saw the wire weaving process.

This is like braiding silk threads like steel cables in previous lives. Finally, these thin wires will be treated and wrapped with silk, glue, oil, etc., and finally become ropes.

Huang Biehe pointed at an armor and explained:

"This is what we developed and used on armor. Although the weaving of the armor itself can keep the blades from falling apart, the strength is still a little lacking."

"But with this kind of rope, the overall strength of the armor will be greater during battle, so that the enemy will not cut off the rope and cause the armor leaves to scatter."

"This has been tested and can be said to be extremely good, reducing the damage rate of the armor."

"It's a pity that this is a newly developed technology that is currently capable of large-scale production and has not yet been popularized."

"But it doesn't matter. Now that the machinery has been manufactured, the overall manufacturing of armor used by our army will only get better and better in the future."

Looking at the rapid drawing of the machine, Liu Wu couldn't help but sigh.

Then he was also curious about it, "Since this thing can be drawn, can it be knitted?"

"You see, although a set of chain mail has good defensive power, it turns out to be very expensive. But with these, whether it is to develop a machine that can be used to weave chain mail, or to directly use it to make it, how can Not everything can be produced quickly.”

Chain mail is the inner lining of armor. It protects against weapons such as swords and axes rather than guns and arrows.

Similarly, especially heavy armor, if the inner lining is chain mail, with the multiple materials composite, it will be difficult to hurt the armor with ordinary blunt objects.

If the conditions are sufficient, chain armor worn on the outside will not be able to protect against arrows, spears, etc., but it will be able to be hacked by knives and axes without any hindrance.

This is the purpose of chain armor. Many generals and nobles like to get a set of such things.

Without him, in the face of a sudden attack, the knife would not be able to cut in.

In response to Liu Wu's question, Huang Biehe smiled.

"We also know this, but the quality of such chain mail is not very good, because we use wrought iron for drawing, not steel, and it is not strong enough."

"The most important thing is that the wire drawing technology is still immature and easy to break."

With that said, Huang Biehe took Liu Wu to another place, which looked like a huge textile factory.

Then he took Liu Wu to one of the machines, pointed at the machine and said:

"You see, this is a textile machine. Its main function is to weave cotton cloth and iron wire together. Although the cloth produced in this way is not as good as shuttle armor, its flexibility and defense are not bad, at least ordinary A sword cannot cut through it.”

With that said, Huang Biehe took Liu Wu to another room. The room was different again, and the armor was also different.

"This is redesigned based on cloth armor. I call it dark armor."

I saw Huang Biehe picking up a set of completed armor. It only had some metal nails on the outside, but when he turned it over slightly, the armor leaves inside were revealed.

"This kind of armor can be said to have better defense, and its comfort is much better than ordinary armor."

As he spoke, Huang Biehe took out his steel knife and slashed at the armor. Liu Wu could see clearly that when the knife struck, it was directly blocked by the leaking nails. The damage to the armor itself was minimal.

"This armor is too tight, Jiangnan can't use it!"

Liu Wu could see the problem with this armor at a glance. This armor was much warmer. Jiang Nan was afraid that he would be too hot to death or fall down from heatstroke while wearing it.

Huang Biehe nodded, "This was developed in response to the requirements of Gui Yishi. In terms of defense and warmth, the effect is extremely good. It can also be continuously stacked and can be worn up to five sets."

"This doesn't mean you can't wear more, but wearing too much will make you more bulky, which is not conducive to action and combat."

"The most important thing is that after testing, we found that the thermal insulation effect of this thing is extremely good. It is completely different from armor that is extremely hot in summer and extremely cold in winter."

Regarding this point, Liu Wu seemed to understand. He seemed to have heard of this kind of thing in his previous life. It was roughly the use of bright metal to reflect heat and better ensure that the body temperature would not evaporate quickly.

It seems like this, Liu Wu can't remember clearly.

But with such good armor, Guiyi's situation in northern Xinjiang will be better, so Liu Wu nodded.

"It's a good invention, but it's been a year since the Guiyi Division expanded its army, and all the armor has been replenished. Do you want to change your clothes?"

Huang Biehe nodded, "That's right. Although the armor suitable for our Guiyi Brigade is not suitable for Jiangnan operations, we only need to reduce the number. We can quickly solve more than 2 sets of equipment in one fell swoop."

"As for these armors, to be honest, they can be made faster than the armors we are using now."

Then, Huang Biehe took Liu Wu to some other places, the most important of which was the strange stoves built one after another.

"Is this a steel-making furnace?"

Liu Wu was curious, Huang Biehe pointed at these stoves excitedly and said:

"These furnaces are used for different purposes, not just for steelmaking."

"Look, this is used to refine iron ore!"

"Look, this is used to refine wrought iron!"

"Look, this is used to refine pig iron!"

Finally, Huang Biehe pointed to some furnaces that were not large and not many in number and said, "This is where steel is made."

"As long as there is no shortage of coal, these furnaces can operate all day long and can produce 130 stones of refined steel."

Liu Wu estimated that he could refine [-] kilograms of steel in one day.

But Liu Wu looked at the entire ordnance depot and saw that almost half of them had such stoves, and frowned in his heart.

Although this efficiency is much higher than that of a blacksmith shop and uses many fewer craftsmen, the output is still too low.

Because according to the current armor style set by the Han army, a set of steel only requires 25 kilograms, so the steel required for the expansion of the army will be 550 million kilograms.

It's 350 kilograms per day. Even if you don't sleep, the smelting alone will take [-] days, almost a year.

Moreover, Liu Wu also discovered a problem, that is, the refining of steel for ordnance requires the use of a large number of furnaces, and then step by step, it can finally become steel.

Huang Biehe said: "Now we feel that although this operation is fast, it is still too cumbersome."

"We are studying how to reduce the number of furnaces and how one furnace can produce hundreds of kilograms of steel in the same time."

In fact, at this time of research, Liu Wu could no longer make any suggestions.

Clearly, the Ordnance Institute has gone its own way.
