As the influence of the money writing order continued to ferment, a large number of money poured into the money house from all over the country, which made the money pile up for a while and there was a short-term shortage of Yongle money, but fortunately, Kira Yoshishi had been prepared for this, and exchanged the 23,000 Guan Gong money accumulated in the inner treasury into Yongle money in advance, which solved the problem of a temporary money shortage, but the large amount of money in his hand became a burden that had to be dealt with.

At present, there are more than ten kinds of iron money circulating in the market, most of which are privately minted by the daimyo in various places since the outbreak of the Yingren Rebellion, among which there are always some extremely poor quality iron money that is marked by the money house at the unit price of ten to one or even fifteen to one, which of course has a great profit, and the people who exchange money feel that they are very lossy and can refuse to exchange, but they soon regret their stupidity.

Because of the influx of a large amount of money, the base price of the money to the Yongle money fell to the base price of the Yongle money, and many merchants who made the difference by trafficking goods back and forth between the two places in Kinai and Kanto almost lost their pants.

It is very profitable to exchange iron money, and the difference in profits is enough for him to get rich, but how to squeeze the maximum profit from the iron money has become a problem he faces, and his solution is to hire senior craftsmen from Kyoto and Sakai Town, and study how to melt and cast iron money to extract pure copper, craftsmen are the meaning of craftsmen, craftsmen are also a kind of craftsmen, and there are the most such craftsmen in Sakai Town and Kyoto, compared to Sakamoto, a new city, there is still a long way to go.

In the process of dismissing a number of craftsmen, a senior craftsman from Sakai Town, Soga Taibei, proposed the process of using the ash blowing method to smelt iron coins and extract pure copper from them.

Kira Yoshishi was very excited about this proposal, and he had also heard of the name of the ash blowing method, but as a layman who did not know the consciousness of the force, he did not know that the ash blowing method also had this magical effect, and the truth that pure copper was hard currency was known all over the world, and Japan was required by the Ming Dynasty to provide enough pure copper for the exploration and trade over the years, and the Ming Dynasty would give Japan the equivalent Yongle money.

The value of pure copper is also equivalent to the value of Yongle money, can the value be the same? Fools can also see the difference, Yongle money is finely made, needless to say, but no matter which dynasty's copper coins do not have pure copper, copper coins must be doped with other metals, there is no profit, the Ming Dynasty will not allow Japan to take a trip with a broken fan, rotten knives to cheat money.

From the mouth of this gray-haired Soga Taibei, who is nearly sixty years old, I learned that he followed his fellow villagers to Kitakyushu to study prospecting, mining and smelting technology when he was a teenager, and lived in Kitakyushu and Saikoku for more than 30 years, until the end of last year, Ouchi's family was disturbed by the miasma, and he returned to his hometown with his family.

His eldest son, Soga and Guard, is a better master of mining and metallurgy than his father, and at the age of thirty-two he has a very powerful forging technique, and it is said that the process of ash blowing is also when Soga and Bing Wei were apprentices, and accidentally learned a process called ash blowing from a Ming craftsman who lived in the Yamaguchi Pavilion, and learned that this process can increase the proportion of pure gold, silver and copper extracted from ore, and then relied on this craft to become a smelting craftsman of the Ouchi family, and his father also became the imperial craftsman of the Ouchi family.

But soon after he learned the ash blowing method, Soga and the guard, who were not willing to be lonely, gave up their preferential treatment and went to the longship place in Bizen Province to learn the famous craft of forging weapons in Nagagawa Province, and stayed in Nagagawa Province for thirteen years, if it weren't for his father seeing that he had always been obsessed with knife work, and didn't even marry a wife and dragged him back to Sakai Town, he might have stayed there for the rest of his life.

Su I Taibei also has a young son named Su I Heibei, who just turned 20 years old this year and inherited his father's and brother's talent, and has a talent that surpasses his brother Su I Heibei in the smelting process, not only followed the family heirloom of the ash blowing method, but also learned his brother ran away from home when he was a teenager, and went to Kyushu Hirado to mix with the Nanban, according to his own words, in the five years he stayed in Pingdo, Nanban and Ming Mandarin can be understood.

This is a very interesting family, Kira Yoshitoki decided to hire the father and son, for this reason also deliberately set up a copper house in the north of Sakamoto Castle near Yamado Town, so that the father and son were responsible for smelting copper coins and extracting copper, and Kira Yoshitoki was able to visit the site when they smelted, so as to figure out what this ash blowing method was all about.

The ash blowing method looks mysterious, in fact, it is to borrow the different melting points of gold, silver, copper and lead, and gradually separate the liquid layer through air oxidation and deposition through the process of high-temperature heating, and then open a gap to discharge the lead liquid and impurities in the upper layer with a large iron rod, and pure copper solution can be obtained.

In addition, it is worth mentioning that the method of refining gold, silver and copper is to add pure lead to the metal mixed with gold, silver and copper, and through the heating and re-deposition separation of lead, the gold, silver and copper can be separated little by little, which is already the most advanced technology of this era.

Having enough copper material can only ensure that he does not lose money, but where should Yongle money come from? You can't sell pure copper for Yongle money, right? So he began to worry about enough Yongle money again, and Kira Yoshishi looked for merchants in Sakai Town to see if there were any craftsmen who could recast Yongle money, but most of these Ming merchants were timid and afraid, and when they heard him show some words, they shook their heads and said that this is not okay and that is not good, which makes him feel helpless, and it is a waste not to mint money with copper materials, but where to find someone who can mint money.

One day at the end of February, Kira Yoshitoki was sitting outside the copper house in a daze, the town where the copper house was located and became a storage place for iron money, so it was natural to send Saijo to guard it, these days Yoshitomi Kira Yoshitomi was worried about Yongle money, the traffic of Yongle money back and forth from the west was too high, and the mountains and rivers were far away along the way, and it was a pit to encounter a wild ambush that was not long-sighted, and the pirate robbery was a pit, not to mention being robbed so unlucky, the daimyo on the road could also draw him to death.

Soga Heibei sneakily walked over and asked Kirayoshi, "Is His Highness Sakamoto worried about the problem of Yongle money?" ”

"Hmm, you see that?" Kira Yoshishi smiled bitterly, he was sad all day long, and ran to the copper house for three days, and it was strange that he was not seen.

"The small one has a way that is not a way, I don't know what His Royal Highness Sakamoto means......"

"Don't sell it." Kira Yoshitoki rubbed his forehead, and when he saw Su Iheibei's look like he wanted to say it but didn't dare to say it, he said with a smile: "If you have anything to say, just say it!" ”

Su I Heibei smiled and said, "Yes! The little one once heard a Ming craftsman inadvertently mention the mother money sand turning method, but when the little one went to ask, the man didn't open his mouth, and said that he was drunk and talked nonsense, but he obviously didn't drink that day, and the little one kept this sentence in his heart, and I don't know if it will help His Royal Highness Sakamoto. ”

Kira Yoshitoki hurriedly asked, "Is that person a craftsman from Kyushu or a craftsman from Sakai Town?" ”

"Craftsmen of the Port of Hirado, Kyushu."

"Why are you kidding me?" Kira Yoshitoki finally couldn't resist the urge to scold, and said for a long time that it was in vain, Kyushu Hirado was so far away that I flew over.

"Huh? What is His Highness Sakamoto talking about? "Su Ihei Bingwei didn't hear clearly, and felt that what Ji Liangyi just said should be a kind of Ming dialect, but the speed of speech was too fast and I didn't know what to say.

"Nothing, let's go back without anything else!"

Su I Heibei hurriedly bowed and retreated, hesitated halfway through, and then turned his head and said: "The little one has seen the craftsman's fellow townsman in Sakai Town, it seems to be a big businessman of the Ming Kingdom in Kyushu, the little one has seen him many times in Kyushu, this merchant often comes to the craftsman to make bronze ware, and the little one still remembers that the merchant's name is Wang Dan." ”
