Daming: If I find a great-grandson, I will teach an emperor through the ages

Chapter 115 Since I’m not going back, let’s get to Little Japan first!
Although he really wanted to stay in Cao Mansion for a while, Zhu Yuanzhang still had memorials to review, and now that Zhu Xiongying no longer had the identity of Cao Wei's adopted son, he had no choice but to leave.

"Since Marquis Zhong Tian is in good health, I feel relieved. Grandpa Huang needs someone to serve him, so I will take my leave first."

After Zhu Xiongying finished speaking, he got up and left with the old imperial doctor.

Cao Wei gave an order, and Xiaoyu took out all the antiques, calligraphy and paintings in his room and found a suitable place to place them. Cao Wei's Cao Mansion suddenly looked much more elegant.

Cao Wei, on the other hand, was sitting in the lobby, thinking about what to do next.

Since you can't go back to the modern technological society, then work hard to develop Ming Dynasty into another modern society, so that you can enjoy it more, right?
However, Cao Wei is still self-aware. He knows that it is impossible for Ming Dynasty to reach the technological level of later generations in a short period of 200 years on his own, but it is still possible to push Ming Dynasty's industry forward for several hundred years.

If you can't build an airplane or a tank, you can still work hard to build a light bulb and radio.

The light bulb requires tungsten filament and glass. Glass is already available. It is just a process problem. The development of tungsten filament is the most important.

There is also radio. The principle is not too complicated either. It uses electric current and magnetic field to transmit signals.

However, if you want these two things to work properly, you must first have electricity.

Cao Wei scratched his head, frowned and thought, "Well... what are the principles of magnetic current motors and radios, magnets, coils..."

After lunch, Cao Wei went to the manufacturing bureau and asked Song Ping to find a piece of red copper.

Red copper also means purple copper. In layman's terms, it is smelted pure copper, which has excellent electrical conductivity and heat transfer properties.

Cao Wei took the red copper and looked at it for a moment, then said to Song Ping: "Make all these red coppers into copper wires, the thickness is about the same as fine flour."

Song Ping blinked, "No!"

Red copper has poor hardness. The imperial court has always mixed some lead and tin to make copper coins. There are only a handful of other uses.

Song Ping didn't understand the purpose of Cao Wei's request for copper wire, but in his eyes, Cao Wei's words were imperial edicts, so he just followed them.

In addition, Song Ping felt that Cao Wei's mental state today was obviously much better than yesterday, and he was extremely happy to see it.

Song Ping picked up the red copper and was about to process it. Cao Wei said something else.

"Go find me some more magnets."

Song Ping responded, turned and left.

A moment later, when Song Ping came to Cao Wei's room again, he saw Cao Wei drawing something on the paper.

Song Ping did not dare to disturb Cao Wei, so he stood on tiptoe and approached gently. He saw that the luggage drawn by Cao Wei on the drawing was somewhat similar to the previous drawing of the steam engine. Both had a thick metal shell, but the internal cross-section But it was revealed that there was an object inside, and it seemed that there were thin threads wrapped around it.

While Cao Wei was thinking, he stopped writing and then saw Song Ping beside him.

"Sir, the magnet you want." Song Ping placed a bunch of magnets wrapped in cloth in his arms on Zhuo Zi.

"Sir, what is this thing you are drawing? It has a weird shape. It looks like a steam engine from the outside, but it is completely different from the inside."

Cao Wei smiled softly, "This is called a magnetic current motor, used to generate electricity."

"Electricity?"

Obviously, Song Ping came into contact with the concept of "power generation" for the first time.

Electricity, shouldn't it be thunder and lightning in the sky?Could it be that this weird thing can also make thunder?
"You will know when I build the motor." Cao Wei said...

As night fell, Cao Wei finally finished drawing all the drawings of the magnetic current motor.

He looked at the magnet on the table and thought he would have to polish it tomorrow.

The next day.

Cao Wei opened his eyes.

[Countdown to return: 9999 days, 16 hours, 51 minutes and 27 seconds]

Although he had seen it yesterday, Cao Wei still felt a little uncomfortable with this long list of numbers.

While the servants were not preparing breakfast, Cao Wei got dressed and went to the yard to do a set of boxing skills.

After breakfast, we went all the way into the palace and came to Fengtian Hall.

When Xu Yungong saw Cao Wei, he came over and asked with concern, "Brother Cao is feeling better."

Cao Wei smiled and said, "Okay, okay, very good."

Seeing these familiar faces again today, Cao Wei felt more and more that perhaps staying in Ming Dynasty was the right thing to do.

While the two were chatting, the voice of the chief eunuch sounded, and the door of the main hall slowly opened.

When they saw Zhu Yuanzhang, all the officials worshiped him as usual.

"Weichen see Your Majesty."

"Excuse the gift, calm down."

"Thank you, Your Majesty."

As a second-grade marquis with no actual duties assigned to Cao Wei, going to court was just a formality for him, and he could just stand there and wait for the emperor to leave.

I thought that after going to court like this today, I could go to the manufacturing bureau to continue developing magnetic current motors, but Zhu Yuanzhang revealed a piece of news.

These days, Japanese pirates have become rampant again. Although the Ming Dynasty already has naval forces stationed on the coast, these days, Japanese pirates seem to be crazy and always attack at night.

There is no doubt about the strength of the navy that Zhu Di personally trained. [-]% of the [-]% Japanese pirates became the dead souls of the Ming Dynasty when they returned to the army. After this continued for several days, the number of Japanese pirates was greatly reduced.

To be honest, when the Ming Dynasty did not have a navy, Japanese pirates were rampant. This was because they found the weaknesses of the Ming Dynasty and tried their best to exploit them.

But now the Ming Dynasty has opened the sea again and organized a large and powerful navy. It wiped out many Japanese pirates a few months ago.

In this way, Japan must have known that the Ming Dynasty reopened the sea, but under such circumstances, Japan still dares to continue to send large-scale Japanese pirates to plunder the coastal areas of the Ming Dynasty. This is putting the face of the Ming Dynasty at its feet. Stepped on!

Japan looks down on Ming Dynasty!Or look down on the Ming Dynasty's navy!

Sure enough, after Zhu Yuanzhang finished telling this news, his face quickly darkened, like a pool of stagnant water!
"We once listed Japan as a country not subject to conquest, but this time the Japanese pirates are too rampant and they don't take our Ming Dynasty seriously! It's really too much!"

"My dear friends, what do you think we should do?"

Cao Wei secretly thought that others didn't know the situation in Japan, but he probably knew something about it.

At this time, the Japanese country was in the conflict between the Southern and Northern Dynasties. Ashikaga Yoshimitsu and Gogameyama each occupied one side, and the two sides fought back and forth.

Given the manufacturing conditions of the Japanese state, such a fight would definitely not last long, or both sides would start to run out of funds. In desperation, they would have no choice but to continue sending Japanese pirates to plunder, at the risk of completely angering the Ming Dynasty.

I just don’t know what role the former remnant Zhang Zicheng played in this...

Lan Yu had a hot temper. After hearing this, he stood outside and shouted, "Your Majesty, the children of the Japanese country clearly deserve a beating. They should send troops to punish them for disrespecting their superior country!"

Some civil servants also stood up and made a fool of themselves, saying, "Your Majesty, our Ming Navy has only been established for a short period of time and has not yet had actual combat experience, and Japan's sea route is far away. I'm afraid it would be inappropriate to send troops rashly. It's better to send envoys to Japan to condemn them." , it would be more appropriate to negotiate peace with them." Lan Yu snorted coldly,
"Hmph! Peace talks? Have you forgotten that in the early years of Hongwu, His Majesty sent envoys to the Japanese country? What happened next? Are you going to let that happen again?"

In the second year of Hongwu, Zhu Yuanzhang condemned the envoys to go to the Japanese country. Unexpectedly, Prince Huailiang of the Japanese country was so bold that he arrested and imprisoned the envoys of the Ming Dynasty. It was not until the following year that the Japanese country was in civil strife that Prince Huairiang was forced to release the captured people. .

If this kind of drama is allowed to happen again, Ming Dynasty will really lose its face.

"This time is not the other. At the beginning of the founding of the Ming Dynasty, the national power was unstable, which allowed the Japanese country to dare to attack the enemy. Now that the Ming Dynasty has a strong national power, strong soldiers and sufficient food, even the Japanese countries dare not make mistakes." Another Qiandu. The censor came out and talked eloquently.

"Then tell me, how many people have the Japanese country taken advantage of over the years and killed us? Is this the end of it?" Lan Yu stared at the two civil servants.

The two of them were shocked by Lan Yu's terrifying aura and did not dare to speak again for a while, but looking at their appearance, it was obvious that they still did not agree with sending troops.

By this time, no one could convince anyone. Zhu Yuanzhang could not decide whether to send troops or envoys to negotiate peace.

Cao Wei felt that it was almost done, so he took a step aside and stood up.

"Your Majesty, I have some foolish opinions and I don't know whether I should speak out or not."

When Zhu Yuanzhang saw Cao Wei standing up, his heart suddenly relaxed, as if with Cao Wei here, no matter how difficult it was, he would be able to solve it easily.

Zhu Yuanzhang himself wondered why he felt this way.

"If Cao Aiqing has anything to say, just say it."

"No," Cao Wei cupped his hand.

"Wei Chen feels that what Mr. Li said makes some sense. As the saying goes, if you know yourself and the enemy, you will win a hundred battles. Before sending troops, you should send someone to the Japanese country to find out the truth."

As soon as Cao Wei finished speaking, Lan Yu looked at him with wide eyes.

He thought Cao Wei would speak for him, and his feelings were here to tear him down.

The censor surnamed Li was a little surprised, but after a moment his face became proud.

Zhu Yuanzhang was also a little surprised that Cao Wei would say this. After all, based on what Cao Wei said when he advocated opening up the sea, it can be seen that he really has no good impression of the Japanese country.

Even Zhu Xiongying, who was standing next to Zhu Yuanzhang, couldn't understand what Cao Wei meant now.

Father...Didn't Marquis Zhong Tian say that Japanese people are all ambitious?Why has your attitude changed so much now?
Just when Zhu Yuanzhang and others were confused, they saw an evil smile on Cao Wei's lips below.

"Your Majesty, as far as I know, although Japan is a small island country, it has an extremely rich silver mine in the country."

As he said that, Cao Wei smiled and waved his sleeves, "The Japanese came to Ming Dynasty to fight the autumn wind for so long, we should also collect some interest."

"Your Majesty, we can first send people to Japan to find out where the silver mine is, and then we can send troops later."

Cao Wei's words caught everyone in the court off guard.

Does Japan have silver mines?
Cao Wei has never been to the sea, how did he know that?

Zhu Yuanzhang, who was sitting on the dragon throne, recalled at this moment that Cao Wei had indeed told him about the train when the train was successfully developed, and that Japan had inexhaustible silver mines.

Although Ma He, who had been sent overseas to search for various high-yielding grains, had not returned yet, after Cao Wei had done many things for the Ming Dynasty, Zhu Yuanzhang was convinced of what Cao Wei said.

Cao Wei is no ordinary person!
Ordinary people cannot build steam engines or trains, nor can ordinary people come up with new methods of making steel and salt.

The words Cao Wei said, no matter how unbelievable they were, all came true in the end.

Just like when Cao Wei said that he could build a train that could pull thousands of people to travel thousands of miles without stopping just by boiling water, just like when Cao Wei said that he could develop a new type of salt-making technology that would allow everyone to eat cheap food. Salt.

When Cao Wei said these words, no one believed them, but in the end they all came true.

However, Zhu Yuanzhang believed in Cao Wei, but it did not mean that others could also believe in Cao Wei without reservation.

"Master Cao," the censor of Li Xingqian just now shouted, "you said that the Japanese country has silver mines, but the Japanese country is separated from the Ming Dynasty by an ocean, thousands of miles away. How did you know?"

"As far as I know, Mr. Cao made a living by farming before entering the court, but he had no chance to go to sea."

"Besides, His Majesty sent people to the Japanese country in the early years of Hongwu. If the Japanese country has such a huge silver mine as Mr. Cao mentioned, hey... I'm afraid we will know about it earlier than Mr. Cao."

After the censor surnamed Li finished speaking, most of the people in the court nodded silently.

"Master Li is right."

"Previous dynasties also had close contacts with Japan. If Japan had such a large silver mine, we should know about it."

……

Everyone's reaction was also as expected by Cao Wei. He listened to the murmurs in his ears and spoke calmly, saying:
"My lords, do you know how much silver the Japanese silver mine can produce in a year?"

Everyone immediately stopped talking and looked at Cao Wei.

"There are more than seven hundred stones!" Cao Wei said loudly.

All of a sudden!
There was an uproar in the main hall, and everyone was shocked by Cao Wei's statement that the annual output of the silver mine was [-] shi.

"Seven hundred stones? Silver?!"

"Seven hundred stones a year?"

"how can that be?"

"Master Cao, are you kidding us?"

Cao Wei curled his lips and said, "Who are you kidding me? Every word I said is true! Bah! Every word is true!"

Everyone still finds it incredible that the annual output is [-] shi, which is...nearly one million taels!

Even Zhu Yuanzhang's eyes widened suddenly, and his big hands firmly grasped the dragon chair!
Cao Wei once told him that Japan's silver mines were inexhaustible and inexhaustible. At that time, he only thought that Cao Wei was exaggerating.

But now that he heard the output of the silver mine, Zhu Yuanzhang realized that what Cao Wei said was true!

Producing one million taels of silver a year...

Damn it!Zhu Yuanzhang felt like he could wake up from his dreams with a smile!
Cao Wei was very satisfied with everyone's reaction.

The silver mine in Japan was called the Iwami Silver Mine. It was excavated in 1526, the fifth year of Jiajing reign in the Ming Dynasty, and was not closed until the 19th century. It was mined for more than 400 years!

According to records, the highest annual silver output of Iwami Silver Mine is 38 tons.

The measurement unit of ton did not exist in the Ming Dynasty. The largest unit of weight in the Ming Dynasty was the stone, and 1 stone was about 120 kilograms.

1 ton is 2000 kilograms, which translates into more than 600 stones.

However, there was a big discrepancy between the weight in ancient times and the weight in later generations. Cao Weilan calculated it carefully and found out that adding two to five would be more than seven hundred stones.
