In Le'an, a mountain stream outside the city, the Shaofu Chief Xu Yu and the Le'an County Magistrate gathered next to a blue pool and watched a Taoist priest toss.

On the periphery, soldiers surrounded the pool and did not allow others to approach.

The Taoist priest in Taoist robe is about thirty years old, thin and has a mustache. He is busy alone at this moment and does two things at the same time.

First, observe a basket of iron sheets immersed in the water of the pond. The basket of iron sheets had been immersed in the pond yesterday.

Second, use an iron pot to boil water in the pond.

Xu Jian and other officials watched carefully as the Taoist priests were busy, regardless of the hot weather and the bites of mosquitoes.

In the iron wok, the light blue water boiled, and the inner wall of the iron wok was red, but not long ago, the inner wall of the iron wok was still black.

The "color rendering" effect is the same as before when I was in the new normal, but the time has been much shorter.

Thinking of this, Xu Li's breathing became rapid and his heartbeat accelerated.

This seems to be true, then, then...

Your Majesty will be amazing after he knows it!!

He looked at the sweaty Taoist priest, and his joy was beyond words.

Although the confusing Le'an County Magistrate and others couldn't quite understand what the Taoist priests did, they gradually realized that their chances of promotion seemed to be coming.

Not long ago, news came from Xinping, abdomen on the North Po Water that someone could burn white porcelain, which made Le'an officials on the South Po Water a little envious.

Xinping had good soil and soil. Since ancient times, pottery was able to be fired, and later porcelain was able to be fired. Now that white porcelain can be fired, the court will inevitably set up official kilns, so Xinping officials will have the opportunity to be promoted.

The north and south Po waters gather in Poyang as Po water. Xinping's porcelain can be easily transported to Pengli Lake, into the river, and transported to Jiankang.

Le'an also has such a way of water, but there is nothing good to produce and transport, which is not comparable to Xinping.

But now it’s different. Le’an County also has amazing production!

The Taoist priest pulled up the bamboo basket, then took out some iron sheets from the basket, and spread them on a dustpan.

"Please look, the iron sheet is already covered with copper."

Xu Jian immediately picked up a piece of iron and looked at it carefully in the sunlight, and the same was true for others.

Everyone could see clearly that the iron sheets that were originally polished have now been dyed red, which means they have turned into copper.

As the Taoist priest said before.

The Taoist priest explained: "The method of gallbladder copper mentioned by me can extract copper from gallbladder water. In the land of Le'an, there are gallbladder water flowing in the mountains, such as this place..."

"The gallbladder flows day and night, and it is endless. Just use my method of gallbladder to continuously extract copper from the water without digging the ground."

"I initially estimate that this forest is just right, as long as it is arranged properly, a few springs can produce thousands of kilograms of copper a year."

As soon as he finished speaking, Le'an officials were extremely excited: This place alone can produce thousands of kilograms of copper every year, so there are so many mining sites, isn't it...

"Okay, very good!"

Xu Jian applauded loudly and looked at the Taoist priest whom he had temporarily found to act: "Master, go to Jiankang with me to tell your Majesty the details."

"Of course." Xu Jian looked at the Le'an official, "Guixian, we must also send someone to Jiankang with our official to explain the situation in Le'an clearly."

“Yes, yes!”

The Le'an County Magistrate and several officials nodded quickly, and each one was very happy.

They saw with their own eyes that copper can be extracted from the water, and this "copper method" is very convenient. It does not require a large amount of green and strong mining and mining ore like other copper ores.

There are many light blue streams in the forests of Le'an. As long as the court sets up officials and mobilizes manpower and material resources, Le'an will become a place for copper production, and the chances of officials' promotion will increase instantly.

There is white porcelain in Xinping, and there is water copper ore veins in Le'an. This is really an unexpected surprise!

In the distance, among the officials' entourage, Li Li looked at the pool and the surrounding mountains and forests, and felt that there were so many mosquitoes.

For large-scale mining, this place requires a labor force of ten thousand people, a state-level material supply, and a large number of military troops to take charge.

So it's useless to make small fuss.

The above is about large-scale mining of copper ores instead of using iron to reduce copper from copper sulfate pentahydrate.

Thinking of this, Li Li was a little distracted.

According to middle school chemistry knowledge, iron can be replaced by copper sulfate solution. The specific manifestation is that the iron sheets immersed in the blue copper sulfate solution will turn red on the surface.

That is, the copper in the solution is replaced and attached to the iron sheet.

It takes time to replace. If the solution concentration is large, or the solution is heated to accelerate concentration, the replacement time will be significantly shortened.

This chemical phenomenon has been discovered in ancient times, which is the Taoist priest who practiced alchemy and practiced immortals, but he regarded it as the "copper dot technique" that can point copper from the gas (copper sulfate solution).

During the Tang and Song dynasties, this "spell" was gradually improved, so the copper gallbladder method appeared, and then the "water method to take copper" appeared.

In the Song Dynasty, the method of gallbladder became the main method of mass production of copper, one of the most famous mines, in the Dexing area of ​​Jiangxi Province in later generations.

This is a little knowledge learned in chemistry class, and Li Li also knows one thing.

In the late 1950s, a giant copper mine was explored in the Dexing area of ​​Jiangxi Province, and then large-scale open-pit mining was carried out, which was once the first copper mine in Asia, Dexing Copper Mine.

The virtues of later generations should be the joy of this era, and at least the regional scope should be roughly overlapping.

Therefore, it is precisely because there are large copper ore veins hidden in the Le'an area that the streams in some places are light blue in the mountains and forests, which means that the water contains a higher concentration of copper sulfate.

Using the method of copper gallbladder, you can easily obtain a large amount of copper.

Li Li carefully asked some minor officials and merchants from Le'an, and confirmed this phenomenon from many sources, so he was confident in offering copper coins.

Copper is equivalent to money to the court. Having a copper mine with low mining costs and high output is equivalent to having a money tree.

This is the great gift Li Li gave to Xu Jian, one of the three worms. Even if it was just a method of taking copper instead of mining ore for open-pit mining, it was enough to make this slander crazy about this.

Only such a slander would reward him with a bite of food. If he reported it to the county party committee and the Poyang royal palace, the effect would not be that good, because the slanderer had strong ability to fulfill his power, but the county party committee and the royal palace did not.

The price is that all the credits on the surface belong to Xu Jian. Xu Jian learned this shocking secret from a Taoist priest You Fang.

However, Li Li wanted to serve as a technical consultant to secretly assist Le'an Guanye's founding.

Li Li withdrew his gaze and began to think about it.

For large-scale mining of this place, it is necessary to find the real veins, which involves large-scale drilling, which requires a lot of manpower and material resources.

Then in peaceful times, the imperial court presided over the mining process and lasted for many years to achieve results.

So it doesn't matter if he gives out the copper method, anyway, he can't mine it by himself.

The Hou Jing Rebellion was about to break out in a few years. Li Li had to hurry up, so he had to take a shortcut. He originally planned to defect to the Poyang Palace, but later decided to defect to the emperor's slander.

Holding the emperor's treacherous ministers will definitely achieve twice the result with half the effort. It is not a pity to pay such a price for this.

After all, a treacherous minister of Heshen cannot be pleased just by wanting you.

The emperor always needs a white glove. While taking on the infamy, he secretly makes money for himself, does some things that damage his reputation, or does dirty work.

Therefore, every emperor has a favor with all dynasties.

Li Li believed that just like Heshen to Emperor Qianlong, the three evils of the Liang Kingdom in this era were the "Heshen" of the Emperor of Daliang, and the minister Zhu Yi was the emperor's pen and sound tube, and Xu Jian and Lu Zheng were the emperor's money bag.
