At the beginning of the founding of the Liang Dynasty, there was an "Ordnance Supervision", which was in charge of the dove workers to gather materials and make military weapons.

During the reign of Emperor Zhenzong, the imperial court established the "Wujing Ordnance Institute", which was solely responsible for manufacturing weapons.

It has many workshops and warehouses——

For example, the "Crossbow Workshop Department" is responsible for handling spears, bows, crossbows, blades, miscellaneous work, and craftsmen.

For example, the "Jiafang Department" handles Jiawei, Jiasheng, tendons, miscellaneous works, and craftsmen.

Such as the "workshop material warehouse", which collects iron, tin, feather arrows, paint and other items.

For example, "Pi Jiao Ku" uses the palm to collect leather and sinews for use in the workshop.

There are also many large workshops such as gunpowder making, Qing Kiln making, Menghuo oil making and so on.

in.

‘Gunpowder making’ and ‘Menghuo oil making’ are what Cao Xin has been focusing on.

…

"On the same day, seven thousand powder arrows were sent out for crossbows and ten thousand powder arrows for bows."

This is part of the production capacity of the Xijing gunpowder factory.

"Gunpowder making" is not simply the production of gunpowder, but also the application of gunpowder.

The "Wu Jing Zong Yao Qian Ji Qiu Tu" written by Renzong during the reign of Emperor Renzong said: "A rocket is used to apply gunpowder to the head of the arrow. It is used with bows and crossbows. The weight of the medicine delivered is based on the power of the bow."

Gunpowder arrows!

This is a crossbow rocket invented by Daliang in the early days of the founding of the People's Republic of China. It consists of an arrowhead and a gunpowder barrel.

The gunpowder barrel is made of cloth or paper, with gunpowder rolled inside. A fuse is inserted into the tail, and the gunpowder is inserted into the barrel. After the gunpowder barrel is made, it is tied near the arrow. When using it, first light the fuse, and then shoot it to the enemy position with a crossbow.

, burning enemy men, horses and food.

This is a fire attack weapon.

In addition to gunpowder arrows, there are six types of fire weapons in Daliang: smoke balls, poison smoke balls, fire sticks, fire starting sticks, pear fire sticks, and thunderballs.

However, gunpowder for beams is still in its infancy and has two obvious weaknesses: first, it is difficult to ignite with an open flame, and requires a burning iron cone to continuously provide heat; second, it cannot fully realize self-oxygen combustion, and it must be ignited in the presence of an open flame.

Only when there is air can it be fully burned.

Technological innovation is not easy.

…

"Gunpowder formula."

"One, two, three, what?"

Cao Xin tried to remember.

Ten years have passed in this life.

Even in my last life, I had already left school and entered society for many years. I had long forgotten the chemistry knowledge learned in junior high and high school, as well as the formula of ‘black powder’ that was not used in daily life.

I only vaguely know that there is a one-two-three ratio. It should contain saltpeter, sulfur, and charcoal. One pound of saltpeter, two pounds of sulfur, and three pounds of charcoal?

Is there any sulfuric acid?

Can't remember clearly.

uncertain.

Furthermore, how to prepare saltpeter, sulfur and sulfuric acid?

don't know.

Is this thing classified into purity?

Or is it pure after it is made?

Do you choose wood for charcoal?

Charcoal and coal should not be the same thing, right?

have no idea.

Not sure.

Making homemade gunpowder is not as easy as imagined.

If you have the skills, you might as well steal it.

"Daliang's gunpowder formula is strictly confidential. Although the quality is not good, if the quantity is large, it can still be used."

Cao Xin has a 'primordial fairyland' and a 'portable space', which is a completely 'self-propelled gunpowder magazine' that explodes all the way, turning him upside down.

Even a top player like Duan Chong might be thrown off his feet if he encounters a sudden encounter.

"You can steal it!"

"You can save it!"

When Cao Xin thought about self-defense methods, the first thing that came to mind was gunpowder.

But apart from this, after getting to know the Xijing Ordnance Institute, I realized that there is something stronger than gunpowder and more suitable for him, which is called "fire oil".

…

The 'Xijing Ordnance Institute' is located in the southwest corner of Xijing City, with numerous workshops and an exclusive dock. It is heavily stationed and guarded very strictly.

Even if there is a "primordial fairyland", it would not be easy for Cao Xin to sneak into it.

And just sneaking in is not enough. You have to find out exactly where the "fire oil", "gunpowder" and "firearms" are stored in the "self-contained" armory.

To do this is more difficult.

In the past, even if Cao Xin had thought about it and even summarized all kinds of information about the 'Ordnance Institute', he had never been reckless and had no idea of ​​using the numerous weapons in the Ordnance Institute.

You must know that the warehouse of the Ordnance Institute is known as the "mountain of accumulated weapons and equipment". There are countless of them and it is definitely a first-class treasure trove.

The 'original fairyland' alone is not enough.

Even if he is trapped inside, his life is not in danger, but if the garrison is alerted and patrols day and night, Cao Xin may be trapped for ten and a half months or even longer, even if he enters and exits the "primordial fairyland".

What's more, it's very possible to come in and out frequently, be discovered frequently, and expose some of the details.

Cao Xin was cautious and patient.

Only today, with the "anchor", does he have the courage.

But it's still not easy.

"Three steps and one post."

"Five steps and one whistle."

"The workshops are separated and the warehouses are scattered and guarded."

"There are also patrols——"

After Cao Xin returned from Caojiazhuang, he spent more than ten consecutive days exploring the armory at night, but made little progress every day. He erred on the side of caution and stopped and went. After spending the whole night, he gained very little.

Of course, he could go to 'night interviews' with craftsmen working at the arsenal, or officials of all sizes, and ask for information.

But there is also a problem——

Cao Xin never harmed innocent people.

Craftsmen are innocent.

As for officials, they also have to spend time screening out whether they are good or bad. They always just pick out the bad ones.

investigation.

Take action.

needs time.

Furthermore, it is easy to alert the enemy. In a key place like the Xijing Ordnance Institute, if there is any slight disturbance, corresponding stress responses may occur.

So if you can't take this step, don't take it.

Although it is a little slow to explore on your own, the advantage is that you are solid and steady, and you have all the details in mind.

Cao Xin is very patient.

He had spent two or three days hunting down Guo Sheng, the leader of Luoxiu County.

Now for the 'treasure' in the arsenal, he would be willing to spend a year and a half, not to mention ten days and a half.

then.

Go every night!

Rain or shine!

He used the attitude of "working slowly and carefully" to outline the layout and defense plan of the weapons station bit by bit——

Post location and manpower allocation.
