Three Kingdoms: I choose Xiao Qiao and Da Qiao, why are you crying, Diao Chan?

Chapter 318 The experiment was successful! (Thanks to the monthly ticket support from Secret Love Lazy Sheep~)
Pyrite is the most widely distributed sulfide in the earth's crust.

Therefore, miners can often mine some pyrite when mining ore or coal.

Moreover, because pyrite is similar in color to gold, it is sometimes mistaken for gold by people who don’t know it.

Therefore, pyrite at that time was called fool's gold.

Fool's Gold is not difficult to obtain and is usually sold in blacksmith shops.

The difficulty lies in how to extract sulfur of higher purity from fool's gold...

Lu Bu pondered for a long time, and suddenly said to Zhang Liao:
"Wenyuan, go to the blacksmith shop and buy a hundred kilograms of fool's gold and transport it to the government treasury. It will be of great use to me when I return."

A hint of doubt flashed in Zhang Liao's eyes, but he didn't ask any further questions.

He knew that his lord had had many strange ideas in his mind since two or three years ago.

The key is that he really used these creative ideas to create many amazing things.

Zhang Liao immediately took the order and left, looking forward to what new things the other party would do...

Lu Bu continued to accompany Cai Yan for a walk on the street.

After buying everything he needed, he took Cai Yan back to the government office.

Wancheng was the capital of his Chu State.

Although the countries here are just common vassal states.

But his Chu State was also the largest vassal state in the world!

After all, in the history of the Han Dynasty, there were not many people who were called "gong".

Cao Cao's calling himself "Duke of Wei" was also an extremely rare behavior.

Of course, the title of Duke of Chu was conferred by the emperor himself, while Cao Cao was given the title of "Duke of Wei" because he forced the emperor to confer the title.

From a legal point of view, it is undoubtedly me, Lord Chu, who is more orthodox!
But now he has fallen out with Liu Xie, so whether this title is orthodox or not is no longer important...

Lu Bu returned to the mansion and came to the treasury alone.

As soon as he entered the treasury, he smelled a faint smell of rotten eggs in the air.

There is no doubt that this is the smell of pyrite.

One hundred kilograms of pyrite is actually about the size of an electric rice cooker.

Soon, grayish-white saltpeter, yellowish-brown pyrite and black charcoal were placed on the table in front of Lu Bu.

As the saying goes, "one saltpeter, two sulphur, and three charcoal."

These three things are the basic materials for making black powder!

Black powder is the earliest form of gunpowder.

It was also gradually discovered by alchemists seven hundred years later in the process of making elixirs.

And now, Lu Bu wants to advance this invention by seven hundred years!

Of course, before making gunpowder, it is necessary to extract medium to high purity sulfur from pyrite.

Lu Bu immediately took out the leather gloves he had prepared in advance.

Although this thing is a bit crude, it can provide the most basic protection.

He used the blade of his Fang Tian Hua Ji to pry off a fist-sized piece of pyrite and crushed it into a medicine bowl.

Then, sesame oil, which had been available since the Han Dynasty, was added to the medicine bowl, which was then placed on a special stove and heated.

Next, he put the green cypress leaves freshly picked from the cypress tree into the medicine bowl and heated them together.

As the temperature of the medicine bowl reaches a certain level, the pyrite in it gradually begins to melt.

After waiting for a long time, the pyrite finally melted completely into liquid and gradually merged with the sesame oil. Then he poured all the liquid in the medicine bowl into a wooden basin filled with cold water to cool it down.

As the temperature dropped, the sesame oil and liquid sulfur, which had just blended together, gradually began to separate into layers.

The liquid sulfur gradually turns back into a solid state as the temperature drops.

After the sulfur was completely formed, Lu Bu immediately took it out of the basin.

The sulfur extracted from the fist-sized pyrite only forms a thin layer at the bottom.

If you knead it into a ball, it will be about the size of a little finger!

It is estimated that the extraction rate is only one thirtieth of the original size...

Although the extraction rate is pitifully small, Lu Bu is extremely excited!
Because this proved that the sulfur extraction method he knew was effective!
Although the purity of the refined sulfur may not be particularly high, the purity can naturally be increased by purifying it several times.

In addition to this refining method, he also masters some more complex purification methods.

Let’s not try it for now, let’s first see if we can make a small amount of black powder.

If not, it won’t be too late to continue purifying sulfur…

Lu Bu suppressed his excitement, cleaned out the small piece of sulfur, kneaded it into a ball and put it into another unused medicine bowl.

He then ground the sulfur into powder.

In separate medicine bowls, grind a piece of charcoal and a piece of saltpeter as finely as possible.

After all the raw materials were prepared, Lu Bu put the three things into the same medicine bowl according to the instructions of "one nitrate, two sulphur and three charcoals".

Of course, the "one saltpeter, two sulfur, and three charcoal" here refers to one pound of saltpeter, two ounces of sulfur, and three ounces of charcoal.

Converted into ratio, it is 10:2:3.

According to this ratio, Lu Bu put all the sulfur, charcoal with two-thirds sulfur content, and five times the amount of saltpeter into the medicine bowl.

After doing all this, Lu Bu looked at the gray powder mixed in the medicine bowl.

I couldn't help but think of the gray powder that I took out from firecrackers in my previous life and that ignited easily.

I think the thing in front of me is already close to that kind of thing.

But in terms of purity and raw materials, there is obviously still a big gap.

Without giving it much thought, Lu Bu immediately took the medicine bowl containing the "trial version of black gunpowder" and went outside the treasury.

It happened that Wei Xu, the captain who was in charge of defeating bandits, came running to find him.

Seeing that there were strange things in Lü Bu's medicine bowl and that he was holding a dragon tongue bow and a fire arrow in his left hand, Wei Xu asked in confusion:
"My Lord, what are you going to do?"

Lu Bu looked at Wei Xu, shook the medicine bowl and said:
"Old Wei, you've come just in time! Let's see if your archery skills have deteriorated."

As he spoke, Lu Bu placed the medicine bowl on the stone table and handed the dragon tongue bow and fire arrows to Wei Xu:
"See if you can shoot the arrow of the rocket into the medicine bowl!"

Wei Xu's mouth corners slightly raised:

"Isn't this simple?"

Wei Xu immediately drew his bow and arrow, looking at the medicine bowl three meters away.

After Lu Bu helped him light the rocket, he just pulled the bowstring back slightly and then released his fingers!

The burning arrow of the rocket fell accurately into the medicine bowl!
Before Wei Xu had time to get excited, there was a sudden explosion in the medicine bowl!
A small ball of sparks jumped out from the medicine bowl and pushed out all the rockets that had fallen into it!
Wei Xu was obviously startled by the sharp sound and the dazzling fire, and asked in horror:
“What…what’s going on?!”

Unlike Wei Xu's fear, Lu Bu's face was full of excitement!

He looked at the black smoke coming out of the medicine bowl and smelled the scent of saltpeter in the air which he had not smelled for a long time, and he couldn't help but burst out laughing!
Future generations will never deceive me!

I really made black powder!
