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

Chapter 167: Generator caused, tungsten ore found!

Before developing repeating muskets and artillery, Cao Wei asked Song Ping to make some accessories according to his own requirements, and he just took them out at this time to continue using them.

Just when Cao Wei was about to ask Song Ping for those parts and continue developing the generator, a question suddenly occurred to him.

Even if the generator is built now, how will it be used?
Electrical equipment such as light bulbs and telegraphs have not yet been built. If only generators are built, wouldn't it become useless?
If you want to put the produced generator to use, you must also start developing electrical equipment such as light bulbs and telegraph machines.

This……

Cao Wei scratched his head, the difficulty suddenly increased dramatically!
Although the principle of a generator is not complicated, it is not easy to make an incandescent lamp and a telegraph.

If you want to make the simplest incandescent lamp, you must first have tungsten filament. However, there is no such thing as tungsten filament in Ming Dynasty. It doesn't even have tungsten ore, let alone refining tungsten ore into tungsten filament.

And if he wanted to make light bulbs, he couldn't do without glass, so he also had to study how to make glass.

Disaster!Cao Wei couldn't help baring his teeth.

But no matter how difficult the road is, if you take it step by step, you will eventually reach the end.

As soon as he turned his head, Cao Wei changed direction and went straight to the palace. He came to the imperial study room to wait without any obstruction.

At this time, Zhu Yuanzhang had not yet gone to court.

Without waiting too long, Zhu Yuanzhang and Zhu Xiongying arrived at the Imperial Study Room one after another.

"Ok?"

Seeing Cao Wei, Zhu Yuanzhang raised his eyebrows.

"You haven't been with Ming'er at home these two days, so what are you doing here?"

"I have something I would like to ask your Majesty to send someone to handle."

Zhu Yuanzhang sat down on the chair and asked, "What's the matter?"

"I want to develop something, but there is a kind of tungsten ore missing. The Ming Dynasty has not yet excavated it, so we need manpower to find this tungsten ore."

"Tungsten mine?" Zhu Yuanzhang frowned.

This was the first time he heard this name, and naturally he had never seen it before. Where should he look for it?

At this time, Zhu Xiongying asked:
"Master Cao, no one has ever seen this tungsten mine before. I don't know what its characteristics are. Even if I send someone to look for it, I have to have a reference."

Zhu Yuanzhang nodded after hearing this, and then looked at Cao Wei.

Cao Wei recalled it in his mind, and he still roughly remembered the characteristics of tungsten ore.

"The characteristics of tungsten ore are...the overall color is black, and the surface is metallic luster. Due to its characteristics, it is usually hexagonal or square in shape, and there are often obvious horizontal stripes on the surface..."

Zhu Yuanzhang and Zhu Xiongying frowned again after hearing this. What Cao Wei said seemed to be not much different from the ordinary stones on the roadside.

If you send someone to look for him like this, it will be like looking for a needle in a haystack.

This is indeed true. Although tungsten ore has unique characteristics, it is still too similar to ordinary stones.

In later generations, some tungsten ore was sometimes mixed into the stones used in some infrastructure projects or for farmers to build houses. Except that the color is darker, it is basically the same as ordinary stones.

Unless a careful person goes out of his way to distinguish them one by one, it is difficult to detect them.

Cao Wei pondered for a moment and suddenly remembered that there seemed to be a lot of tungsten ore distributed in Yunnan.

"As far as I know, there are many tungsten mines distributed in Yunnan. Your Majesty can ask people to search carefully, and they will definitely gain something."

Zhu Yuanzhang and Zhu Xiongying's grandfather and grandson looked at each other strangely.

It was Cao Wei who told about the silver mine in Japan, and he led his people to find it. Now there is a tungsten mine, and he also told the exact location.

Is Cao Wei really omniscient and omnipotent?

Where on earth did he know so many secrets?

However, Zhu Yuanzhang immediately drafted an edict and sent people to Yunnan to start looking for tungsten mines.

"What are you tinkering with this time?" Zhu Yuanzhang asked the eunuch chief to send the edict out, and then raised his head and asked Cao Wei.

"Generator, light bulb," Cao Wei replied.

"What is that?" There were two more novel nouns, and Zhu Yuanzhang couldn't understand them.

Cao Wei smiled, "Before they were created, I couldn't explain why, but they do have a great effect."

"A generator, as the name suggests, can produce electricity independently," Cao Wei pointed to his head, "just like thunder and lightning."

Zhu Yuanzhang and Zhu Xiongying immediately opened their mouths, feeling surprised.

Cao Wei continued to talk here, "With electricity, you can light up light bulbs. The role of light bulbs is to replace candles, which can greatly save material consumption and is more convenient. A light bulb can be worth thousands of dollars." A hundred candles.”

"There is also a telegraph machine, which uses electric current and magnetic field to transmit messages. It is effective in real time. Even if the two parties are thousands of miles apart, they can immediately receive the message from the other party."

Zhu Yuanzhang's eyes widened even more, and the wrinkles on his forehead piled up.

"You can know what the other person is saying even though you are thousands of miles away? It's so miraculous!"

Zhu Xiongying suddenly remembered that Cao Wei seemed to have said these words to him.

At that time, he only regarded it as a joke. After all, it was just an idea of ​​Cao Wei, but he did not expect that Cao Wei would realize this idea today!

"In addition, there are many applications of electricity, but they all require corresponding equipment, and I have to do it step by step."

Zhu Yuanzhang nodded. What Cao Wei said just now was so amazing and magical that Zhu Yuanzhang couldn't wait to see the generators, light bulbs and other things that were built.

"Since you want to develop such an important thing, you can't spend too much energy on other things. From today on, you don't have to go to court for anything that is not important. Let's ask the officials to go to Cao Mansion every day. You If anything happens, just ask them to report it.”

Cao Wei was stunned. He didn't expect Zhu Yuanzhang to give him such a great privilege.

"I thank you, Your Majesty."

Zhu Yuanzhang waved his hand, "You have extraordinary abilities and can do many things, which will be beneficial to Ming Dynasty. I won't restrict you too much. I just hope that you will restrain yourself and don't become inert."

"I would like to follow His Majesty's instructions."

……

After leaving the palace, Cao Wei came to the manufacturing bureau again.

The tungsten mine has been sent to search for it, and now he is preparing to develop a generator first.

The principle of the generator is not complicated. It uses metal conductors to cut magnetic field lines to generate current.

The metal conductor itself contains electrons. When cutting the magnetic field lines, the electrons move under the action of Lorentz force, forming an electric current.

Lines are then used to form a closed circuit. When current flows, electrical equipment can operate on the current.Cao Wei found Song Ping and asked him to find the accessories he had made before, a coil made of red copper wire wrapped with copper wire, and a magnet.

Then, Cao Wei began to make the generator casing to install the coils and magnets...

the other side,
Thousands of miles away in Yunnan.

Zhu Yuanzhang's edict was delivered to the residence of the Marquis of Xiping in less than half a month under the quick work of the messenger.

The original Marquis of Xiping was Mu Ying, Zhu Yuanzhang's former adopted son.

However, when the prince Zhu Biao died in the 25th year of Hongwu, Mu Ying died of a serious illness because of her deep relationship with Zhu Biao and was too sad.

Later, Mu Ying's eldest son Mu Chun inherited Mu Ying's title and became the current Marquis of Xiping, in charge of everything in Yunnan.

Although the Mu family is only granted the title of Marquis, they have the ultimate authority in Yunnan!
Because of its remote location, all the people in Yunnan may not be very fond of the current emperor Zhu Yuanzhang, but they have great respect and respect for Mu Ying and the Mu family.

When the Yuan army was pushed back to Mobei, there were still remnants in the Yunnan area. It took Mu Ying as the main force. It took two years and many small and large battles to wipe out the remnants of the Bei Yuan army.

After that, Mu Ying stayed in Yunnan and took up positions in Yunnan. She ordered soldiers to farm fields, build education, build water conservancy, and maintain border defenses, which gradually freed the people of Yunnan from the war, and Mu Ying became a hero in the hearts of the people in Yunnan.

In the 25th year of Hongwu's reign, after the news of Mu Ying's death came out, "bureaucrats, commoners, subordinates, soldiers, Jianhuang, and Tiaobai all rushed to the door and cried on the road" in Yunnan.

When Mu Ying's eldest son Mu Chun was ordered to escort his father's coffin back to the capital for burial, and when it was lifted out of Jinma Mountain in Yunnan, the people of Yunnan "sent tens of thousands of people", which shows that the Mu family has absolute prestige in Yunnan.

Mu Ying's eldest son Mu Chun is very much like his father. He is a loyal minister and general of the Ming Dynasty. He is absolutely loyal to Zhu Yuanzhang and the Ming Dynasty.

When Zhu Yuanzhang's edict was sent to Mu Ying's eldest son Mu Chun, the Xiping Marquis did not say anything. He immediately organized people to search for the so-called "tungsten mine" and released the news that anyone who found the tungsten mine would , the Marquis of Xiping will be rewarded heavily.

More than twenty days passed in a row.

One day at noon, an old man rushed to the gate of Xipinghou Mansion.

The old man shouted loudly in front of the door, "The old man has found a tungsten mine. Please see Mr. Xipinghou."

The housekeeper at the Xipinghou Mansion found Muchun and informed him of the news that someone wanted to see him.

"Sir, this is already the tenth time he claims to have found a tungsten mine. Are you... still seeing me?" the housekeeper asked, standing next to Muchun.

In the face of huge profits, there is never a shortage of brave people who try to make up for their losses. In the past 20 days, people have been coming to Xipinghou Mansion claiming to have found tungsten mines.

But after Muchun personally inspected it, he found that what they brought did not meet the characteristics of the tungsten ore mentioned in the edict at all. They were all ordinary stones.

Muchun rubbed his brows,
"Your Majesty's order, how can we not do our best? Let's bring him in."

"No!" the butler replied, turned and left.
After a while, the housekeeper brought the old man to Mu Chun.

"The old man has met Mr. Xipinghou." The old man knelt down and bowed to the ground as soon as he saw him.

"Get up, old man." Muchun waved his hand.

"Thank you, Mr. Xipinghou."

Muchun looked the old man up and down.
"You said...you found tungsten ore?"

"Correct!"

Hearing this, the old man opened the package in his arms. Inside was a pile of stones. The shape was no different from ordinary stones, but the color was darker.

Muchun noticed this difference and stepped forward to take a closer look. He was shocked to find that these stones were exactly the same as what the edict said!
"The whole body is black, with a metallic luster, and there are horizontal stripes on it..."

Muchun raised his eyes and looked at the old man,
"Old man, where did you find this stone?"

Seeing Muchun's reaction, the old man was convinced that he was not wrong. A proud and honest smile appeared on his face for a moment.

"To be fair to Mr. Xipinghou, old man, when I heard you were looking for this mist ore, I didn't take it to heart. I thought that this good thing would not happen to the old man..."

Muchun didn't expect that the old man was still a chatterbox, and he started chattering incessantly at this time. However, he had nothing to do, so he didn't interrupt the old man and listened to what he kept talking.

"A few days ago, the old man went up the mountain to pick mushrooms. He passed by a pile of rocks and wanted to rest, but he saw that these rocks were the same as those mentioned in His Majesty's edict."

"The old man thought to himself, if this is really the mist ore, wouldn't it be helpful to Mr. Xipinghou? Even if it wasn't, the old man wouldn't suffer much from a trip, so he hurriedly brought the stone."

Muchun nodded,
"Yes, this stone is exactly what His Majesty's decree said. It must be tungsten ore. Old man, do you still remember where you found these stones?"

The old man pointed in the direction, "It's on the hill behind the old man's house."

Muchun's mouth twitched,
"Where is your home, old man?"

"Wenshan Malipo County."

After getting the answer, Muchun finally felt at ease, and immediately asked the butler to prepare the reward he had agreed on in advance, which was 20 taels of silver.

After the housekeeper took the silver coins and handed them to the old man, Muchun ordered the housekeeper to arrange manpower and go back with the old man to check the location of the tungsten mine.

After the old man left, Muchun immediately wrote a secret letter and sent someone to quickly deliver it to Yingtian Mansion.

It took another half a month before the news that Muchun had found the tungsten mine reached Cao Wei's ears.

At this time, he had made a simple generator. He connected copper wires to both sides of the generator, turned the coil inside, and felt the tingling current when he touched the copper wires on both sides with his hands.

Although it is very crude and the power is very small, the generator has been initially built.

When he heard that the tungsten mine had been found, Cao Wei became energetic, which meant that the incandescent light bulb was waving to him.

However, to be sure, Cao Wei decided to go to Yunnan in person to see if what Muchun found was tungsten ore.

After consulting Zhu Yuanzhang, Cao Wei took his wife Zhu Hanming and a group of followers and set off.

This trip happened to be a honeymoon with Zhu Hanming.

Cao Wei and his companions' journey was not fast. It took them more than a month to reach the Yunnan border.

Mu Chun had already received the news and sent someone to take care of them. As soon as Cao Wei and his party entered Yunnan, they were found by the person in charge and brought to the residence of the Marquis of Xiping.

Mu Chun is about the same age as Cao Wei, only two years younger than Cao Wei. However, Mu Chun, who comes from a family of military generals, also looks like he has the aura of a general.

Seeing Cao Wei, Muchun saluted very respectfully and politely.

"My lower official, Mu Chun, has met Grand Master Cao and Mrs. Cao. Even if Mu Chun is in Yunnan, he can always hear the great reputation of Grand Master Cao. When I meet him today, he is indeed well-deserved."

Cao Wei waved his hand, "You're welcome, you're welcome. The Marquis of Xiping is also a talented person. His Majesty often said that with you in Yunnan, he can sit back and relax."

After some pleasantries, Cao Wei asked about the tungsten mine.

"Before Grand Master Cao arrived, I had already ordered people to go and inspect the place where the tungsten mine was discovered. Grand Master Cao arrived in Yunnan today for the first time and was tired of traveling and traveling. Tomorrow I will personally accompany Grand Master Cao to Malipo County in Wenshan to have a look."

Muchun did everything right, and Cao Wei nodded in agreement.
