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

Chapter 188 Wireless telegraphy, sound transmission thousands of miles!

Thinking about it as he walked, when he returned to Cao Mansion, Cao Wei saw an old doctor taking Zhu Hanming's pulse in the hall, with the maid Xiaoyu standing beside him.

The old doctor Cao Wei had some impression that he was the royal doctor Chen in the palace. When he lived in Zhengkan Village, he was sent by Zhu Yuanzhang to see his body.

Seeing this scene, Cao Wei's heart tightened and he walked over quickly. However, seeing that Dr. Chen was concentrating on feeling his pulse, he did not interfere and stood aside to wait.

Doctor Chen was seen with his eyes closed, his expression very focused. After changing several gestures, he opened his eyes and withdrew his hand.

"What's going on?" Cao Wei couldn't help but asked.

Zhu Hanming smiled faintly:

"It's nothing serious. I just feel a little uncomfortable in my stomach these days. I have nothing to do, so I asked Dr. Chen to come and take a look."

Cao Wei nodded and then looked at the old doctor.

"Chen Yuyi, is there anything wrong with her body after taking tea?"

Doctor Chen suddenly laughed, his gray beard trembling:

"The old man would like to congratulate Grand Master Cao. Princess Hanming is very happy."

After his words fell, Cao Wei was a little in disbelief.

He looked at Zhu Hanming and saw both surprise and joy in her eyes.

Is Zhu Hanming pregnant?

Am I going to be a father?

Cao Wei's head was buzzing for a while, this surprise came so suddenly!

"Chen, Imperial Physician Chen, don't get it wrong."

Doctor Chen chuckled and said:

"The old man started practicing medicine when he was less than ten years old. After completing the training, he has been practicing medicine for forty years. This happy pulse... the old man will never be wrong about it."

Cao Wei suddenly became excited, "Can Dr. Chen tell whether she is having a boy or a girl?"

"Master Cao is making things difficult for me, old man. Even if Hua Tuo is reincarnated, it will be difficult to tell the gender of the fetus in the belly based on the pulse."

Only then did Cao Wei realize that he was so excited that he had forgotten that there was no accurate way to detect the gender of the fetus.

Cao Wei scratched his head awkwardly and smiled, then waved his hand and ordered Xiaoyu:

"Doctor Chen's hard work, go to the accounting room and prepare the money."

Xiaoyu also recovered from the shock just now, responded, and walked out quickly.

After a while, Xiaoyu came back with more than a dozen taels of silver. Cao Wei took it, turned around and stuffed it into the hands of Imperial Doctor Chen.

Even if the patient is not found, after a happy event is detected, the host family will usually prepare a little silver.

Imperial Physician Chen was not polite, took it generously and put it in his arms, "Then the old man is enjoying Grand Master Cao's happiness."

Then, Dr. Chen prescribed a secret recipe for fetal safety and gave it to Cao Wei.

"This prescription can nourish the body and prevent pregnancy. Princess Hanming takes one dose every day, and coupled with dietary supplements, it can make the fetus in her belly thrive."

Zhu Hanming nodded, "Thank you, Dr. Chen."

Then Chen Yuyi stood up and left, and Cao Wei asked Xiaoyu to see Chen Yuyi off.

Looking at Zhu Hanming, Cao Wei suddenly felt like he was touching nothing, for fear of affecting the fetus in his belly. He was a father for the first time and he really had no experience.

Seeing Cao Wei's helpless look, Zhu Hanming smiled sweetly and said:

"I am pregnant with a child, and I am not turning into a hedgehog that cannot be touched. My husband does not need to be so cautious."

Cao Wei chuckled and said, "In the past, I was so busy making things happen that I didn't notice it at all. I really shouldn't have."

"Everything your husband does is for the sake of the Ming Dynasty. This is what a true man should do, and you don't have to worry about it."

"I just hope that I can live up to my expectations and give my husband a boy..."

Cao Wei shook his head, "You can't say that. No matter if the wife gives birth to a boy or a girl, they are our flesh and blood. Whether it is a son or a daughter, I like them all."

In this era, it is most common to favor sons over daughters. Of course, Cao Wei also wants a son to inherit his current family business, but he does not want to put too much pressure on Zhu Hanming.

Xiaoyu came back after sending Imperial Doctor Chen out of the Cao Mansion. Her steps were much brisker, and it was obvious that she was very happy.

Madam may be giving birth to a young master!

When Cao Wei saw her coming back, he picked up the prescription and gave it to her:

"Xiaoyu, hurry up and get the medicine according to the prescription. Come back and give it to Madam."

Xiaoyu took it with a smile and quickly left Cao's house.

Zhu Hanming smiled and said:

"He said there's no rush. It's late at night and I don't mind the hassle."

Cao Wei grinned, "No, I'm afraid if I don't bother enough, my children will blame me as a father in the future..."

After saying that, he stepped forward and gently stroked Zhu Hanming's belly.

Faintly, Cao Wei had a strange feeling.

He is more deeply connected to this world, and soon, his bloodline will always exist in this world...

……

The news of Zhu Hanming's pregnancy spread quickly. After Concubine Han in the palace learned about it, she began to run to the Cao Mansion every two days to take care of Zhu Hanming personally.

Zhu Xiongying would not say anything about this, and Zhu Yuanzhang would not stop him. Even because of his love for Cao Wei and Zhu Hanming, Zhu Yuanzhang began to often follow Concubine Han to the Cao Mansion.

Cao Wei continued to lead people in the manufacturing bureau to study wireless telegraphy.

The successful creation of the previous light bulb indicated that Ming Dynasty had taken the first step towards industrialization.

Industrialization is modernization.

At this time, the Ming Dynasty was the most primitive agricultural society. There was still a semi-modernization between modernization and modernization. This was an unavoidable journey.

Now Cao Wei is working hard for this semi-modernization.

Zhu Hanming was pregnant, which gave Cao Wei even greater motivation.

The biggest benefit of modernization is that it brings a lot of convenience to people.

Now he is committed to researching industrial development and technological innovation, partly for the sake of his family and future generations.

After all, only he can create those things for future generations. After his son or daughter is born, he can also enjoy happiness, right?

Now that we had generators and light bulbs, it was only a matter of time before we could create wireless telegraphy.

The production principle of wireless telegraphy is much simpler than that of light bulbs. It uses current to change electromagnetic signals to generate electromagnetic waves to send messages.

The original telegraph machine had no encryption and no need for FM or AM, so it did not need tubes and transistors, only the two poles of the power supply.

Because as long as current flows, an electromagnetic interference magnetic field will definitely be generated. The most difficult thing is how to transmit and receive these electromagnetic wave signals, which requires a lot of experiments...

Another day.

Cao Wei and Song Ping were in the room of the Manufacturing Bureau, constantly experimenting with the electrified telegraph model on the table.

As Cao Wei kept pressing the pedal, the small light bulb on the telegraph machine flashed and made a "beep" sound.

Another telegraph machine that receives signals also has a small light bulb on it. After the signal transmitter senses the electromagnetic waves, the small light bulb on it also starts to flicker on and off, and a small sound is also emitted.

"It's done!"

Cao Wei was refreshed!

It’s really done! Song Ping's eyes widened in disbelief when he saw this magical phenomenon in front of him.

"So the telegraph machine can send messages thousands of miles away?"

Cao Wei shook his head,

"Such electromagnetic waves alone are not enough, a transfer station is also needed."

Just at noon, the two stopped what they were doing, and Cao Wei began to explain the principles and functions of the transfer station to Song Ping.

At this moment, Zhao Heng came over.

"Sir, rubber from Yunnan has been delivered."

"Go and have a look."

The three of them came to the door of the manufacturing bureau. There were many large boxes at the door, which were covered with layers of rubber of different colors.

When developing light bulbs before, the issues of gas filling and sealing inside the light bulbs were also involved.

Although these two problems were eventually solved and the light bulb was successfully manufactured before the military parade, the rubber seal used by Cao Wei and others still had many disadvantages, such as rapid aging and so on.

Later, Cao Wei remembered that there were rubber trees in tropical areas such as Myanmar and Siam, so he quickly sent people to look for them and successfully found them without any surprise.

Then Muchun, who was in Yunnan, started collecting and making rubber according to Professor Cao Wei's method.

It is also not difficult to make simple rubber products. The most difficult thing is to collect formic acid to remove impurities from the rubber, such as iron ions and organic fatty acids.

Cao Wei thought hard and finally remembered that the original name of formic acid was actually formic acid, which was extracted from the secretions of ants.

After sending the message to Muchun, the latter collected a large amount of formic acid and it took several months to finally produce the first batch of rubber.

Cao Wei reached out and pulled out a rubber mat. It was very elastic and tough, no problem!

With this batch of rubber, the life of the light bulbs produced can be greatly improved!

There are also generators and wireless telegraph machines, both of which require the use of rubber.

In other words, as industrialization begins, more and more things will be inseparable from rubber.

"Reply to Marquis Xiping and tell him that there is no problem with the quality of the rubber and ask him to continue production."

"No!" Zhao Heng responded with his hands raised.

……

In May of the thirty-first year of Hongwu.

The first practical wireless telegraph machine in Ming Dynasty was developed.

Cao Wei moved it to the main hall and demonstrated its effect in front of the officials. Everyone who saw it was amazed!

This technology, which can transmit sounds thousands of miles away and conduct conversations across the air, is like a miracle to all the officials in the court at this time!

With this wireless telegraph machine, no matter where you are, as long as you can receive the signal from the relay tower, you can contact another wireless telegraph machine!

The emergence of the wireless telegraph machine completely ended the problem of feudal dynasties in the past that the imperial power could not reach the borders, the imperial power could not go to the countryside, and the imperial power could not go to the countryside!

There is no doubt that after the creation of the wireless telegraph machine, the central court's control over the entire country directly improved dramatically!

Not only that, as the Ming Dynasty opened the sea, the territory of the Ming Dynasty became larger and larger, and it involved more and more geographical locations in the entire world.

Without wireless telegraph machines, no matter how powerful the Ming Dynasty was, it would still have to bow to the problem of long distances.

And with the wireless telegraph machine, Ming Dynasty could flex its muscles as much as it wanted!

As long as there are enough resources that Ming Dynasty needs to control, it can send troops to occupy it, and then set up towers and wireless telegraphs. There is no need to worry about the distance and the inability to fully control it.

Furthermore, with real-time and effective communication methods, once any changes occurred in the Ming Dynasty's border areas or overseas places, the central court could be notified as soon as possible, and the emperor and officials could respond as quickly as possible. The strategy is to turn passivity into initiative!

Everyone present was not stupid, and they understood the great role of the wireless telegraph without further explanation.

"If Grand Master Cao achieves heavenly merit again, he should publish a biography and write a book!"

"It is indeed a great blessing that Ming Dynasty has Grand Master Cao!"

"Master Cao's wisdom puts the subordinates to shame..."

……

If it weren't for Cao Wei who was now the first-class Grand Master and Dazhuguo in the court, all the officials in the court would have asked for credit again for Cao Wei.

It is precisely because Cao Wei is now extremely powerful that when he developed a wireless telegraph machine, Zhu Xiongying only rewarded him with some money and silk.

It's not that Zhu Xiongying doesn't want to reward him, but that Cao Wei has made it impossible for him to do anything now.

After the reward, Zhu Xiongying actually ordered people to start writing a book and biography for Cao Wei. This operation directly refreshed Cao Wei!

After working hard for the Ming Dynasty for so many years, the reward he received was not small.

But only this book and biography...Cao Wei can even regard him as the first-class reward! What a great honor!

So what if he is a first-grade master? So what if it’s the Dazhu Kingdom? Even if he is as wealthy as his country, his figure will eventually fade away in the tide of history.

However, publishing a book and writing a biography can completely record his name and life. When future generations see this ancient record, they will be able to see his magnificent life!

The spiritual value is simply immeasurable!

Looking at Zhu Xiongying sitting on the dragon chair, Cao Wei smiled with sincerity.

……

As the days passed, Cao Wei continued to improve the wireless telegraph machine, hoping to maximize the role of the telegraph machine.

the other side,

Zhu Hanming's figure gradually became more pregnant, and Zhu Yuanzhang and Concubine Han visited the Cao Mansion more frequently.

Cao Wei left the manufacturing bureau again and when he returned to Cao Mansion, Zhu Yuanzhang had not left yet.

The two of them came to the lobby and talked without a word.

"Has the wireless telegraph machine been improved in any way?" Zhu Yuanzhang asked.

"Recent testing showed that communication between two provinces can be achieved without loading a relay tower. With the addition of a relay tower, the range can be expanded to two more provinces," Cao Wei replied.

"In addition, a set of communication codes must be compiled to be used with the wireless telegraph machine..."

Zhu Yuanzhang picked up the tea cup at hand and took a sip, feeling very happy in his heart.

"We really didn't expect that you could develop such a wonderful thing as a wireless telegraph machine, great!"

Zhu Di came back from Japan a while ago and asked Zhu Xiongying to let him take full power to take over Japan.

Even Zhu Yuanzhang was not sure how to deal with Zhu Di's request.

You can't say for sure. Zhu Di stayed in the Japanese country for four years and defeated the Japanese country. He worked hard and deserved it.

To be precise...

Zhu Yuanzhang felt a little worried for his eldest grandson when he placed a vassal king with a heavy army on a remote archipelago isolated from the Ming Dynasty.

It's not that he doesn't trust Zhu Di, but that when a person is in a very high position, sometimes the decisions he has to make are beyond his control.

Sometimes people create momentum, and sometimes momentum creates people!

Zhu Di is also a person with outstanding abilities. If there is any slight change, Ming Dynasty will be in a hurry at least.

And Zhu Xiongying was worthy of being his grandson, Zhu Yuanzhang. He had a kingly demeanor and even more ruthlessness. He nodded directly and agreed to Zhu Di's request.

Zhu Yuanzhang could not think of a better way to deal with this, so he could only let it go, but he was still slightly worried in his heart.

But when he learned that Cao Wei had developed a wireless telegraph machine and understood its function, Zhu Yuanzhang suddenly felt reassured!
