At the beginning of the founding of the country, Daliang set up a 'military weapons supervisor', who was in charge of the decree of dove workers gathering materials and manufacturing weapons.

During the reign of Zhenzong, the imperial court set up the 'Wujing Military Weapons Institute', which was responsible for the manufacture of weapons.

There are many workshops and warehouses under it——

For example, the 'Crossbow Workshop Department', which is in charge of cashiers' spears, bows, crossbows, blades, miscellaneous craftsmen and craftsmen.

Such as the 'Jiafang Department', the cashier of the stomach, rope, tendons, miscellaneous work and craftsmen.

For example, the 'workshop material warehouse' collects iron tin, feather arrows, paint and other things.

Such as the 'leather horn library', the palm of the leather, tendon corners, for the use of the workshop.

There are many large workshops such as gunpowder making, green kiln making, and Menghuo oil making.

Thereinto.

'Made of gunpowder' and 'made of fire oil' are the focus of Cao Xin's attention.

……

"On the same day, 7,000 gunpowder arrows were sent out for crossbows, and 10,000 gunpowder arrows for bows and arrows."

This is part of the production capacity of Xijing gunpowder.

'Gunpowder making' is not simply the production of gunpowder, but more the application of gunpowder.

In the reign of Renzong, there is a cloud in the "Martial Arts General Essentials of the Former Collection: Instrument Diagram": "Rockets, gunpowder is applied to the head of the arrow, and the bow and crossbow are universal, and the weight of the medicine is subject to the bow force." ”

Gunpowder arrows!

This is a bow and crossbow rocket created at the beginning of the founding of the country, which is composed of two parts: an arrow and a gunpowder cartridge.

The gunpowder cartridge is rolled with cloth or paper, and the gunpowder is rolled inside, and the fuse is inserted at the tail, and the gunpowder is in the barrel. The powder cartridge is made and tied to the vicinity of the arrow. When used, first light the fuse, and then shoot the bow and crossbow into the enemy line, burning the enemy's men, horses, and grain and grass.

This is a fire attack weapon.

In addition to gunpowder arrows, there are six kinds of firearms such as smoke balls, poison smoke balls, fire rings, fire rings, tribulus fire balls, and thunderbolt balls.

"The Point Guard Is Here"

However, the gunpowder of the girder is still in its infancy, and there are two obvious weaknesses: first, it is difficult to ignite with an open flame, and it can only be ignited by continuously providing heat with a burnt iron cone; Second, self-oxygen combustion cannot be fully realized, and it can only be fully burned in the presence of air.

Technological innovation is not easy.

……

"Gunpowder formula."

"One, two, what, three, what?"

Cao Xin struggled to recall.

Ten years have passed since this life.

Even in the previous life, I have left the campus and entered the society for several years, and I have long remembered the chemistry knowledge of junior high school and high school, and the formula of 'black powder' that cannot be used in daily life.

I only vaguely know what is the ratio of one, two, three, there should be saltpeter, sulfur, charcoal, one pound of saltpeter, two pounds of sulfur and three pounds of charcoal?

Is there any sulfuric acid?

I don't remember exactly.

Up in the air.

Also, how to make saltpeter, sulfur, and sulfuric acid?

I don't understand.

Is this thing pure?

Or is it pure?

Does charcoal pick wood?

Charcoal and coal shouldn't be the same thing, right?

I don't know.

I don't know.

Homemade gunpowder is not as simple as you think.

With this kung fu, it is better to steal.

"The gunpowder formula of the girder is strictly confidential, although the quality is not good, but if the quantity is large, it can still be used."

Cao Xin has a 'primitive fairy world' and a 'portable space', which is completely a 'self-propelled powder magazine', and he has been vigorous all the way, turning him upside down.

is a top master like Duan Chong, who is not cold, and he may also be bombed.

"You can steal!"

"You can save it!"

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

But in addition to this, after learning about the Xijing Arsenal, I learned that there was something more powerful than gunpowder and more suitable for him, called 'Menghuo oil'.

……

The "Xijing Arsenal" is located in the southwest corner of the Xijing City, with many workshops, exclusive docks, heavy garrisons, and very strict guards.

Even if there is a 'Primordial Immortal Realm', it is not easy for Cao Xin to enter it.

Moreover, it is not enough to just go in, but also to accurately find out the warehouses where the 'Menghuo oil', 'gunpowder' and 'firearms' are stored in the 'self-contained' ordnance station.

To do this, it is more difficult.

In the past, even though Cao Xin had thoughts, and even summarized all kinds of information about the 'Arsenal', he was never reckless, and he did not have the idea of fighting the vast number of weapons in the Arsenal.

You must know that the warehouse of the Ordnance Institute is known as the 'mountain of tired weapons', and there are countless of them, and it is definitely a first-class treasure house.

The 'Primordial Immortal Realm' alone is far from enough.

If he was trapped inside, although his life was safe, if he caused the garrison to be on alert and patrol day and night, Cao Xin might be trapped for ten days and a half months or even longer even if he entered and exited the 'Primordial Immortal Realm'.

What's more, it is very possible to enter and exit frequently, be found frequently, and expose part of the bottom line.

Cao Xin is cautious, forbearant and patient.

It is only now, with the 'anchor', that he has the courage to do so.

But it's still not easy.

"Three steps and one post."

"Five steps and one sentry."

"The workshops are separated, the warehouses are scattered, and there are guards."

"And the patrols—"

After Cao Xin returned from Caojiazhuang, he visited the weapons station for more than ten consecutive days and nights, and there was little progress every day. Prudence comes first, stop-and-go, and the whole night is consumed, and little is gained.

Of course, he could go to the 'night visit' of the craftsmen who worked in the ordnance station, or officials of all sizes, to ask for information.

But there's something wrong with that –

Cao Xin never harmed innocent people.

Artisans are innocent.

If an official is a official, he has to take time to sift through whether it is good or bad, and he always only needs to pick and choose the bad.

Survey.

Take action.

It takes time.

In addition, this is easy to startle the snake, and in a critical place like the 'Xijing Military Weapons Institute', there may be a corresponding stress response if there is a slight disturbance.

Therefore, if you can not take this step, you will not go.

Although it is a little slower to explore on your own, it is better to be solid and steady, and all the details are in your heart.

Cao Xin was patient.

In order to hunt down Guo Sheng, the head catcher in Luoxiu County, he spent two or three days before and after.

Now for the sake of the 'treasure' in the arsenal, let alone ten days and a half months, even a year and a half, he is willing.

Thereupon.

Go night and night!

Come rain come shine!

He used the attitude of 'slow work and meticulous work' to outline the pattern and deployment map of the ordnance station little by little-

Sentry position, manpower allocation.

Patrol routes, frequency of people.

The location of the workshop and the warehouse is the top priority, find a place, determine a place, but do not rush to do it, just step on the point.

Cao Xin is most looking forward to the rainy night.

The heavy rain was pouring down, and the gatekeepers, guards, and patrols all had varying degrees of laxity, coupled with the sound of the rain and the vision of the rain, which made Cao Xin, who had infiltrated it, even more difficult to find.

However, unfortunately, in December, it rarely rains, but snowflakes.

When there was snow on the ground, Cao Xin couldn't do it without a trace, so he could only temporarily stop work for a few days.

In this way, it is intermittent, slow and methodical, and persevering.

At the end of the year, more than a month has passed, and the situation of the 'ordnance station' has not yet been clarified, and it is far from the same.

The Ordnance Institute is open all year round, and the annual customs are not relaxed.

It was Cao Xin who gave himself a holiday.

……

Xijing City is vast and has many entertainment venues, including but not limited to teahouses, green houses, gambling houses, etc.

Among them, gambling houses are the most.

Liang people are good gamblers, and Xijing is the worst.

In the streets and alleys, you can see gambling houses and casinos everywhere, cockfighting, dog fighting, cricket fighting, and everything can be gambled.

There are many gambling houses, and there are big and small bets.

A few pennies for a small amount.

There is no upper limit to the big ones.

Otherwise, how did the Ge family in Changxi lose their huge property?

From the peddlers and pawns, to the dignitaries, all of them gamble.

Cao Xin's age, the Qinglou is not suitable to go, the teahouse is not interesting, the small song of the Goolan is tasteless, and only the gambling house is the most attractive.

"There are many gamblers in the gambling house, and the three religions and nine streams are gathered, and they are well-informed."

"I'll get the ordnance from the armory in the future, and I'll have to find a place for them."

It's always right to hang out in the gambling house.

In the past, I was young, and it was too eye-catching. But now, there is a fifth-layer 'Shou Shiqing Editing and Adjustment Method', which can incarnate as a 'sick old man'-

The old man who is in his early sixties of one meter will not be too eye-catching.

Old gambler!

Old gambler!

The old man also has a gambler!
