Lao Zhu is indeed short of money, or since he became the emperor, there has been no time when he is not short of money.

Hongwu Tongbao is intermittently cast, and the reason why the casting has been stopped several times is because of the lack of copper in the imperial court.

Later, the Daming treasure banknotes were released, which was relieved a lot, but as the treasure banknotes were printed more and more, the depreciation of this thing became faster and faster, so fast that the common people would not recognize it.

As a last resort, he ordered to be minted a few more times, but he was always unable to meet the embarrassment of Daming's lack of money.

Therefore, when he saw the large amount of silver money coming into the account every month on the eldest grandson's side, Lao Zhu was so envious that his eyes were about to catch fire.

But he was just talking, and when he saw Erhu and Zhu Li looking at him in surprise, he shut up in disgust.

"Erhu, where is the place to exchange that coin?"

"Back to the emperor, not far ahead, there is a copper coin at the door."

Zhu Li saw that there was no one near Zuo, so he stepped forward and said.

"Father, the son thinks that the eldest nephew is not guilty of privately minting copper coins."

"I have seen the copper coin just now, it can only be regarded as a gadget, for people to use as a souvenir, to prove that it has swam through the palace of King Wu......"

Lao Zhu heard the words and said twice with his nose.

"You don't have to cover up for the rebel grandson, if it weren't for us beating him every once in a while, what we saw today would be "Taisun Tongbao"! ”

Zhu Li's heart tightened when he heard this, and secretly scolded Zhu Yunxi for being bold, so many vassal kings in the Ming Dynasty didn't dare to mint copper coins privately, this grandson dared to do this under the nose of the old man, it was really not wrong to kill him!

Although Zhu Li hated to death in his heart, he still had to cover up for Zhu Yunxi.

"Father's words are serious, Zhu Yunxi's child is the most filial, and he will never do such a big rebellious thing......"

"Perhaps!"

Lao Zhu sighed, and then followed Erhu to the commemorative coin exchange office in front.

When a few people entered the commemorative coin exchange office, it was already crowded. There were also many people driving horse-drawn carts, which were loaded with a cart full of copper coins.

In order not to let the emperor wait for a long time, Erhu immediately squeezed in with his big waist and round body, and shouted at the people inside.

"Spread out!"

"It's temporarily closed today, and those who want to exchange commemorative coins will come back later!"

When the person in charge of the exchange office heard this, he stood up from the counter on the spot. Seeing that it was Erhu who spoke, he sat down again.

It's just that the merchants gathered at the exchange office didn't recognize Erhu, and when they saw him cut in line, they even threatened to temporarily close their business, and they immediately became noisy.

"Who are you, such a big breath!"

"Even if the people from the palace come over, they have to line up honestly!"

"Which green onion are you, don't count the queue, and don't want us to exchange copper coins!"

Lao Zhu heard the clamor of the surrounding businessmen, and without waiting for Erhu to reply, he rushed back.

"We're his grandfather!"

Lao Zhu put down this sentence, and strode into the exchange office, lined up in front of the counter and asked them to take out all kinds of coins.

The person in charge of the exchange office glanced at Erhu, and when he saw that Erhu gave him a look and asked him to cooperate, he no longer hesitated at the moment, and took out several commemorative coins from Wu Wanggong and put them on the counter.

"How much does this official want to exchange?"

"Copper coins are one to ten, small silver coins are one to one hundred, large silver coins are one to one, and gold coins are one to five thousand."

"If you exchange copper coins for copper coins, there is a daily limit. There is no upper limit on how much silver can be exchanged for copper coins. There is also a limit to the amount of silver that can be exchanged for silver coins, and there is a limit of 10 per day. Similarly, there is no upper limit on the amount of gold exchanged for silver and copper coins. ”

"Don't be busy with introductions, let's just come and have a look!"

Lao Zhu picked up a piece of silver coin and looked at it, only to see that there was a profile portrait of himself on it. I picked up a smaller silver coin, and saw that it was replaced with a portrait of the crown prince Zhu Biao.

Lao Zhu knew what the so-called grandfather's money, son's money, and grandson's money meant.

Dare to love that grandson is to print three generations of their grandparents and grandchildren on coins!

Lao Zhu saw that his face value was the largest, and subconsciously thought that it was the eldest grandson's respect for him, and his heart suddenly felt like he had eaten honey, sweet.

Not really

Know, this thing has nothing to do with respect.

As the saying goes, the larger the face value, the worse the liquidity. The smaller the face value, the better the liquidity.

The reason why Zhu Yunxi printed himself on the copper coin was just to show off his prosperous beauty, lalala......

Lao Zhu curiously picked up a gold coin and looked at it, he thought that Zhu Wusi's name would be printed on it, but he didn't think that he would only see a small turtle on it!

"This is ancestral money?"

"How can the ancestors draw turtles on their money, it's really unreasonable!"

"Back to the emperor, this is not a turtle, this is Xuanwu, but a divine beast. It also corresponds to the name of Xuanwu Lake, also known as Xuanwu coin. ”

"As for the ancestral money, it's just the name of the people......"

The guy who was still talking to Lao Zhu about the exchange ratio just now, when he heard Erhu's words, he was so frightened that he knelt on the ground.

"Grass People...... The grass people meet ......"

"Excuse me!"

Lao Zhu flicked his sleeves and turned to leave, but after walking a few steps, he turned around, grabbed a row of commemorative coins on the counter and said hatefully.

"We're all so angry that we almost forgot the incriminating evidence!"

Zhu Li and Erhu glanced at each other, and sweated for a certain little rebel grandson in their hearts, secretly saying that someone might be beaten again......

Zhu Li deliberately took two steps behind, tugged on Erhu's sleeve and said in a low voice.

"Hurry up and send someone to inform my eldest nephew!"

Erhu glanced at Lao Zhu, who walked with the wind, and shook his head vigilantly.

"His Royal Highness the King of Jin, it's not that you shirk your humble duties, but you really don't dare to be humble in your duties."

"The emperor warned him about his humble position yesterday, saying that if he dared to report to the third emperor and grandson again, he would turn his humble position into a eunuch!"

"Uh-uh......"

Zhu Li sighed in his heart when he heard this, and could only pray that his eldest nephew Jiren had his own natural appearance.

Lao Zhu came out of the Wu Palace, got into the carriage directly, and then went to the iron-smelting workshop non-stop.

Although Lao Zhu had also seen big chimneys in the iron-smelting workshop of the Ordnance Bureau, when he saw hundreds of big chimneys standing at the foot of the lime mountain, he was still stunned by the scene in front of him.

"This is what kind of blast furnace you are talking about?"

Erhu has never been here, he has listened to the reports of Jinyiwei's subordinates. Therefore, at first glance, I was shocked to see such a big movement in this place.

"It should be!"

"Ask someone for a low job!"

After Erhu said this, he casually called someone over and asked him to find the steward of this place.

After a while, a small flag of the brocade guard ran over. Seeing that the person looking for him was the Tiger Ancestor, he hurriedly knelt down and kowtowed.

"Little Zhao Mu, meet the tiger master!"

"Tell us what these stoves are for!"

"Also, treat that old man with respect, and you will answer whatever he asks!"

Zhao Mu glanced at Lao Zhu, and was secretly taken aback in his heart, saying in his heart, could this person be Your Majesty?

"Dare to ask Master Hu, this is today's ......"

"Humph!"

"Don't ask what you shouldn't!"

"The little one understands!"

Zhao Mu hurriedly got up from the ground and introduced the wonderful use of the blast furnace here to a few people.

Lao Zhu saw that the steward here turned out to be a person from Jinyiwei, and he couldn't help but speak in a sloppy manner.

"The stewards here are all Jinyiwei?"

Zhao Mu looked at Erhu when he heard this, and saw Erhu nodding at him, so he replied stubbornly.

"Returning to this nobleman, the third emperor grandson said that this is a critical place, and only by handing it over to the Son of Heaven's army can you rest assured!"

When Lao Zhu heard this, he snorted coldly.

"Even if you count that rebellious grandson, there is still a bit of respect!"

When Zhao Mu heard this, he said in his heart that this was not what I asked, it was the old man himself!

"Zhao Mu, the lowly Jinyi Wei Xiaoqi, meet Your Majesty, long live my emperor, long live ......"

Lao Zhu saw the craftsmen around him look over, and quickly waved his sleeves and said.

"Get up and talk back!"

"No!"

"I wonder what Your Majesty wants to see?"

Lao Zhu pointed to the stove next to him.

"Follow first

Let's talk about this, this thing can really smelt thousands of catties of iron at a time? ”

Zhao Mu explained when he heard this.

"It's not as exaggerated as rumored, it's just that it can hold thousands of catties of iron ore at a time, and the iron smelted each time is less than a thousand catties!"

"Hiss......"

Lao Zhu secretly said when he heard this, this guy has such a big breath, and it is too little to make a thousand catties of iron at one time?

You must know that ordinary workshops, a maximum of a few hundred catties of material at a time, can produce a hundred and ten catties of iron, it can already be called a large workshop.

There are hundreds of furnaces here, and even if each furnace is only used once a day, the amount of iron produced a day is 100,000 catties.

It is 30 million catties a year, which is higher than the output of the whole Daming workshop together!

"Tell us the truth of this thing, why can you smelt so much iron at one time!"

"Back to Your Majesty, it's not that you are lowly and hide your personal interests, but you don't know much about this thing."

"Humble officials usually only manage people, and do not care about ......"

When Lao Zhu heard Zhao Mu say this, he didn't have the slightest idea of being angry, and felt that this person was quite sincere and a rare honest person.

"Then call someone who can explain it!"

"This ......"

Zhao Mu's face immediately showed embarrassment when he heard this, although there are many craftsmen here, but there are really few people who can explain the truth of blast furnace ironmaking. Many times, they also work according to the rules set by the Three Emperors and Suns, and they don't know much more than their own mallet.

At this moment, a young man dressed in a scholar's costume and carrying a notepad walked in front of several people.

Seeing this, Zhao Mu hurriedly greeted.

"Sun Xiucai, come over quickly!"

Sun Jizu turned his head when he heard this, and saw that it was Zhao Xiaoqi, the steward of this place, who called him, so he reluctantly walked over.

"Zhao Xiaoqi, I still have to take stock of iron materials, but I don't have time to chat with you here. If you have something to say, hurry up, don't delay *** work. ”

"Sun Xiucai, this noble man wants to know how the blast furnace works, we are a martial artist, where do you understand the Tao here, I can only bother you to introduce it."

"Oh, that's such a trifle!"

Sun Jizu led a few people to an abandoned blast furnace and led a few people to walk in through the door that opened at the bottom.

"This is where the wood and coke are stacked, this is the place where the limestone is stacked, and at the top is the hopper for iron ore."

"This method of steelmaking is through the strong pressure difference between the air inlet and the air outlet, the wood, coal and other things, into frivolous gas, when the frivolous gas burns, it can release a larger flame, so that this flame will smelt the top of the iron ore into molten iron, and then discharge through the outlet here......"

"If you want to imitate, my Ming Iron and Steel Chamber of Commerce is willing to send construction drawings and send experienced craftsmen to guide you."

When Zhu Yuanzhang heard Sun Jizu's explanation, he only felt lonely when he heard it. However, when he heard the last sentence, his face suddenly showed a look of incomprehension.

He clearly remembered that Jinyiwei Xiaoqi had just said that this place was important, so he sent Jinyiwei to take care of it. How did you get to Sun Xiucai, the secrets of this place can be said casually, and even the drawings can be provided for free?

"This Xiucai, if you tell the secret of the blast furnace like this, you are not afraid of the punishment of the Three Emperors and Suns?"

Sun Xiucai looked at Lao Zhu in a daze when he heard this, and asked puzzledly.

"Punish what?"

"This is what the Three Emperor Sun means, the Three Emperor Sun has never had the idea of cherishing the broom!"

"Although the blast furnace is wonderful, in the eyes of the Three Emperors, it is not a great thing."

"The reason why the Three Emperors and Grandsons let Jinyiwei take care of this place is not to prevent others from peeping. Instead, in the name of the Son of Heaven of Jinyiwei, he showed his heart to His Majesty the Emperor and proved that what he had done was above board and upright, and there was no deliberate concealment! ”

Lao Zhu was stunned when he heard this, and he felt as if he didn't know the rebel grandson.

"The Three Emperors and Grandsons have such good intentions?"

Sun Jizu hurriedly explained when he heard this.

"It's not kind."

"The third emperor grandson said that His Majesty the Emperor is a cautious eye, even if he can hide it from His Majesty for a while, he can't hide it from His Majesty for a lifetime......"

"The Three Emperors and Grandsons also said ......"

Zhu Li saw that this dog show was not finished, so he raised his foot and kicked it.

"Shut up!"
