My villain, Ximen Qing, married Pan Jinlian at the beginning

In the system mall, there are many technologies in the category of 'technology'.

Of course, the price also varies from high to low. Among them, the technology of distilled liquor purification that Ximen Qing once mastered is also included in the option of 'technology'.

And the price of this distilled liquor purification technology is 1000 exchange points.

This is not a lot, but it is also a lot of exchange points.

The current source of Ximenqing's funds mainly comes from this distilled liquor purification technology.

But Ximenqing didn't want it, and only relied on distilled liquor purification technology to grab money.

So Ximen Qing began to look at the option of 'technology'.

After thinking for a long time, a 'thing' suddenly caught Ximen Qing's eyes.

This is a technique called the 'yellow mud water spraying sugar method'.

In layman's terms, this technology is the production method of white sugar purification.

White sugar entered China from the national tribute of Dashi and other countries in the early Song Dynasty.

But the white sugar at that time was white granulated sugar, which was not very white.

Later, the Chinese in the Ming Dynasty processed the real white as snow sugar by themselves, which was the "yellow mud water drenching sugar method".

Since the Ming Dynasty, China has changed from a sugar importing country to an exporting country, not only exporting to Japan, but also exporting to India, the source of sugar.

There are many types of white sugar now, and the price gap is also very large.

The price of white sugar also depends on the whiteness of the white sugar.

For example, the price difference between better white sugar and worse white sugar can be several times or even dozens of times.

The white sugar on the market now, even if it is the highest grade and the most expensive white sugar, in Ximen Qing's opinion, it is not white!
If Ximenqing can have this 'yellow mud water drenching sugar method', Ximenqing can make white sugar as white as snow.

In an instant, it can directly crush all similar products on the market just like the appearance of distilled wine.

At the same time, the production cost of this "yellow mud water drenching sugar method" is far lower than the production cost of traditional white sugar.

This can bring a lot of money to Ximen Qing!
Then there is the most important point, which is the price of this 'yellow mud water sugar method', which is only 500 exchange points.

Ximen Qing is completely enough for exchange points to exchange.

So after thinking of this, Ximen Qing did not hesitate, and said to the system: "System, help me exchange this 500 exchange points for the 'Yellow Mud Water Spraying Sugar Method'!"

"The host consumed 500 exchange points and successfully exchanged for the 'Yellow Mud Water Spraying Sugar Method'!" said the mechanized voice of the system.

There were originally 1400 exchange points left, but now 500 points have been consumed.

In Ximen Qing today, there are only 900 exchange points left.

According to the remaining 900 point exchange points, Ximen Qing continued to search for the appropriate technology in this 'technical' option to exchange.

Not long after that, Ximen Qing was immediately attracted by another technology.

This technique is called 'basic lime mortar cement technique'.

In the vernacular, this technology is the most basic technology of cement production.

Cement is the main material for future buildings, and its hardness is far beyond that of houses made of loess, clay and wood.

With cement technology, Ximen Qing can build it, a 'steel fortress' beyond this era!
Ximen Qing now has more and more guards around him, plus he exists in such a troubled world.

There were not only a large number of uprisings and battles inside the Song Dynasty, but there were also foreign races staring at them outside.

That's why Ximen Qing wants to keep himself and those around him safe in this troubled world.

Then Ximenqing must also have a certain ability to protect himself.

And to create a force of his own, this is what Ximen Qing has always wanted to do, and it is what Ximen Qing is doing now.

After owning the cement, Ximen Qing can create an 'indestructible' site.

Even if a strong enemy invades in the future, I am afraid that even if you want to enter Ximen Qing's territory, you will never be able to do it!
But suddenly, Ximen Qing changed his mind and temporarily gave up the idea of ​​exchanging this technology.

First of all, this technique consumes 800 exchange points.

The second is the current Ximen Qing, who only has more than a hundred people under his command.

It is still too early to redeem this technology.

"This cement technology will definitely be indispensable in the future, but at this critical moment, I still need some technology to defend against the enemy, or some technology that can make money."

"After all, if I have more and more soldiers under my command in the future, it will take a lot of expenses to feed these people!"

After thinking of this, Ximen Qing continued to look for some technologies that can produce practical effects and are sufficient for exchange points to exchange.

And at this moment, Ximen Qing discovered another technique.

After discovering this technology, the pleasantly surprised Ximen Qing said without hesitation, "That's it!"

This technique is called 'Flintlock Production Technique'!
The flintlock was invented by Mahan, a Frenchman born in 1547 (in the middle of the 16th century) in a family of gunsmiths, locksmiths and watchmakers.

It is improved on the basis of the revolver, with the spring steel wheel removed, a piece of flint clamped on the jaw of the hammer, and an anvil beside the fire hole.

When shooting, pull the trigger, and under the action of the spring, the flint will be hit heavily on the edge of the fire door, sparks will come out, and the gunpowder will be ignited to fire.

The shooting process is greatly simplified, the firing rate and shooting accuracy are improved, the use is convenient, and the cost is low, which is convenient for mass production.

In the middle of the 17th century, many European armies were generally equipped with flintlock guns. It lasted for more than 1848 years in 200.

The current era of Ximenqing is the Northern Song Dynasty. Although the Northern Song Dynasty had the use of gunpowder in military affairs.

In the early years of the Northern Song Dynasty, there were already three gunpowder formulas, and they were initially used in actual combat.

They are cannon gunpowder method, poison smoke ball gunpowder method, caltrop fireball gunpowder method.

The formula of these gunpowder is nothing more than "one yellow, two nitrates and three charcoals".

The army of the Northern Song Dynasty applied gunpowder launch technology to siege warfare.

A trebuchet filled with gunpowder will be more powerful.

However, the use of gunpowder was very limited at that time, and the huge explosive power of gunpowder could not be exerted. It could only increase the temperature of the surface of the thrown object and emit billowing smoke.

But even so, Song Jun was invincible.

However, the Song Army did not pay too much attention to gunpowder, so it was very backward in the development and application of gunpowder.

Although the current Song army battles, gunpowder has also played some role.

However, in Ximen Qing's view, this method of using gunpowder is too elementary and crude.

If there is this 'Flintlock', it will surely sweep all the firearms of this era, and even become the strongest individual weapon!

If each of Ximen Qing's guards could be equipped with a flintlock musket, then the combat effectiveness of Ximen Qing's guards would at least double.

Even an ordinary person holding such a flintlock gun can cause great danger to a first-class martial artist.

Of course, the premise is that at least the head must be accurate, otherwise it will be useless to miss someone.
