At the beginning of the civil castle, the Ming God of War was a little panicked

Chapter 430 Fresh Things
Jin Yiwei received the order and all evacuated from the palace.

A thrilling poisoning case ended thereupon, and the haze shrouded in the Forbidden City quietly dissipated.

When Yuan Bin learned of this result, he was extremely troubled.

To poison the emperor, at least the nine tribes must start.

However, the principal culprit who was found out after a lot of effort turned out to be the current crown prince...

To be exact, there are also the second prince and the third prince. These three brothers committed crimes in a gang.

If this kind of thing was placed in the Yongle Dynasty, it would be serious.

Emperor Taizong was 40 years old when he raised his troops to Jingnan, and he had been emperor for 21 years. His three sons had already grown up, and each of them was able to take charge of his own side. The battle for the reserve position was extremely fierce.

Regardless of whether it is the prince, the king of Han or the king of Zhao, even if it is a good grandson, whoever dares to poison Emperor Taizong will never have a way out.

The current situation is quite different, the prince is only eight years old, and the other two accomplices are six years old and the other four years old.

Is it too early to say that the prince wants to drive Lao Tzu down early and take the stage by himself?

What's more, the two princes are also present, and we really have to investigate, who will pass the throne to after the three brothers finish playing together...

Yuan Bin was at a loss, so he simply removed Jin Yiwei and acted as if nothing had happened.

As for the punishment the crown prince and the two princes will receive, that is the emperor's housework and has nothing to do with him.

Everything in the imperial palace was back to normal, but there were rumors that on that day, there was a burst of heart-piercing crying from the eastern palace.

There was more than one person listening to the voice, there seemed to be two or three...

After several days of recuperation, Zhu Qizhen was finally able to get out of bed and walk.

During this period, Empress Dowager Sun came to visit occasionally, and Empress Qian and Wan Zhen'er took care of her on weekdays.

The Imperial Hospital once came to see them and prescribed some recuperating soups, but Zhu Qizhen didn't give them a good look.

Empress Qian had already told the truth about the situation at that time, and after the Tai Hospital arrived, she immediately made the decision to die.

If it hadn't been for Wan Zhener's desperate rescue, she would have really collapsed at that time.

Zhu Qizhen has long wanted to rectify the Tai Hospital, and now he has made up his mind that it must be changed, and it must be changed drastically!
What hereditary medicine, what this medical book, that allusion, all overthrow and start over!
At the same time, he himself was in a state of embarrassment, despite the strong wind and waves breaking through, he almost lost his life because of a bowl of fish soup from the three filial sons.

In retrospect, life is really impermanent!

Concubine Zhou Guifei and Concubine Wan Huan had already confessed their crimes, and they were also terrified when such a big incident happened.

But how can it be?

Zhu Qizhen didn't hold them accountable, and blamed himself for this kind of thing. He didn't look carefully when he was drinking fish soup, and there was puffer fish!
The one who should blame the most is Tong Xuan, this guy doesn't do research well every day, and only thinks about electric fish.

If you want to eat fish, there are plenty of them on the street. If you set aside so much silver, you can research an electric fish device. Do you have a grudge against fish?
Bellin was also terrified when she learned the whole story.

If Wan Zhen'er hadn't been rescued in time, the emperor would have died, wouldn't the sky be falling!
At the moment, he established a rule in the Academy of Sciences that no one is allowed to study equipment related to electric fish, even fishing, net fishing and other things are not allowed to touch.

In order to completely eliminate hidden dangers, another rectification notice was issued, requiring the electric power research laboratory to stop all projects and wait for verification before proceeding.

After doing all this, I was still uneasy. After thinking about it, I sent a rectification notice to Xu Pu's telephone research team.

Xu Pu was simply baffled, and wanted to ask what happened, but the reply he got was... Who asked you to study electricity!
As a result, two laboratories related to electricity in the Academy of Sciences were simultaneously closed for rectification.

All researchers are not allowed to leave the Xishan base without permission, and have nothing to do, so they can only go back to the hut to sleep.

Tong Xuan and Xu Pu's identities are quite special, and they are temporarily isolated in a warehouse, waiting for the verification results.

The two had nothing to do in the warehouse, they could only chat with one another.

However, the chats are all related to electricity. No matter what the topic is, we must return to electricity in the end.

Seeing Tong Xuan sighing again and again, Xu Pu comforted him, "His Royal Highness also made a mistake out of good intentions. This has nothing to do with your research results, so don't blame yourself too much."

Tong Xuan didn't know it, but the whole thing was caused by himself, so it was impossible to say that he didn't blame himself.

"His Royal Highness is afraid that he will be beaten."

Xu Pu said: "Your Highness is still young, if you get beaten, you can get beaten, it's fine."

"I'm not worried about His Highness being beaten, the main reason is..."

Tong Xuan thought for a while, and continued: "You may not know that His Highness is very interested in electricity, and he is very talented. I am worried that he will be affected by this incident, and he will not dare to touch electricity again. Isn't it a pity? "

Xu Pu laughed and said, "What did Brother Tong say? His Highness is the heir apparent, and he will inherit the throne in the future. Even if he is interested in electricity and has a good talent, how can he spend his whole life studying electricity like an ordinary person?"

Tong Xuan couldn't help laughing, and said: "I'm narrow-minded... By the way, how is your phone call going?"

Xu Pu shook his head and said, "It's been so long without a breakthrough, it's very difficult."

"Could it be that there is a problem with the research direction?"

"The direction was set by the emperor himself, so there shouldn't be any problems. The key now is the materials. Many things are simply not up to expectations. It's difficult to try hundreds of materials for just one component!"

Tong Xuan asked again: "Have you ever thought about making a simple model machine first?"

"simple……"

Xu Pu was stunned suddenly, and murmured: "Yeah, why don't you make a simple one?"

This sentence gave him a lot of inspiration. After getting the drawings, he put all his energy on the design and production of each component.

However, at the current level, it is really difficult to meet the requirements.

"Brother Tong reminded me that the phone is too complicated, we can try to make a simplified one, for example..."

Xu Pu became interested, found a pen and paper, and began to draw pictures.

"According to the blueprint given by the emperor, the telephone is used to transmit voices. As long as the line is connected, in theory, two people can talk to each other thousands of miles apart."

"I have studied carefully. The principle of the telephone is different from that of the microphone. The microphone directly transmits the sound, while the telephone converts our voice into an electrical signal, conducts it to the other end through the line, and then converts the electrical signal back into sound."

These words are very awkward, and I am afraid that only Tong Xuan can understand them.

After all, he was the patriarch who studied electricity in the Ming Dynasty. Even if you haven't heard many terms, you can roughly guess them.

Xu Pu became more and more excited as he spoke, and continued: "This is also the difficulty of the telephone, which is the conversion between sound and electrical signals. The emperor said that semiconductors are needed. Our team has not yet figured out what semiconductors are. However, just now Brother Tong's words inspired me a lot!"

"If we abandon the conversion between electrical signals and sounds, and directly use electrical signals to convey information, can we achieve the same effect?"

Tong Xuan pondered for a moment, then asked, "How to send messages with electrical signals?"

Xu Pu already had an idea, and said, "I'm not sure if it will succeed, I still need Brother Tong's cooperation!"

Tong Xuan asked again: "We don't have experimental equipment now, what are you going to do?"

Xu Pu looked around and said, "Enough!"

This is the warehouse of the electric power laboratory, which stores a lot of materials and equipment.

For the novelty that Xu Pu just conceived, the things here are enough.

The two chatted for a long time, settled their thoughts, and began to prepare.

First, what is needed is a battery.

Tong Xuan has already researched the storage battery, which requires zinc rods, sulfuric acid, copper rods, etc. These things can be found in the warehouse.

This kind of battery is very primitive, because the power is very low, relatively speaking, the cost becomes very high.

In general, it is only used in the laboratory.

The simple phone that Tong Xuan thought of was not actually called a phone, but had an exclusive name called a telegram.

Whether it's a phone call or a telegram, it's just a name and it doesn't matter.

With the cooperation of the two, a battery was quickly assembled.

Then, Xu Pu found wood boards, copper wires, iron nails, copper sheets and other materials.

Today's copper wires no longer need to be wrapped with cotton yarn, but painted with a layer of paint on the outside, which is quick and safe.

After everything was ready, Xu Pu started to assemble.

According to the idea just thought up, first take the wooden board and place it flat, nail in the long nails, wait until the nails are exposed two centimeters from the wooden board, and then stop. , Wind the copper wire, and the transmitter is almost made.

After finishing the telegraph, they followed the same pattern and assembled a telegraph.

The next step is to set up the wires. The warehouse is very large. The two deliberately lengthened the wires, and placed the transmitter and receiver at two opposite corners of the warehouse.

Finally, everything was ready, and the first telegraph machine in the Ming Dynasty was ready.

Xu Pu came to the position of the transmitter and slowly turned it on...

Beep beep!

Tong Xuan clearly saw that the electromagnet surrounding the copper wire vibrated and made a sound.

It worked!
The two cheered and celebrated the success of the first experiment.

However, here comes the problem.

Tong Xuan asked: "How do we confirm the news to be delivered?"

This thing can't talk, so it beeps a few times, what can it mean?
Xu Pu frowned and thought, "It needs to be effective at a specific time and under specific requirements. For example, when the machine beeps, it means there is an enemy attack."

"You mean, use this thing as a beacon tower?"

"Roughly so."

"How many times did it ring?"

"Three beeps, because I activated it three times."

"You mean, every time it is turned on, it will beep?"

"Not bad!"

"In that case... I have an idea!"

"Brother Tong, please speak!"

Tong Xuan only felt a flash of inspiration in his mind, and said, "Why don't you use the frequency of the sound to express a certain meaning?"

"Wonderful!"

Xu Pu clapped his hands and said, "For example, one sound means safety, two sounds means enemy attack, three sounds and four sounds can also have other meanings, how about that?"

Tong Xuan nodded and said: "Then we need to make a special book to record the meanings represented by the sounds."

"book……"

Xu Pu's eyes flickered, and he saw a book beside him.

Randomly copied, it is the first published nature encyclopedia.

Tong Xuan didn't know what he was doing with the book, so he said, "The things in this book are all basic, and they won't be of much help to you."

Xu Pu had other plans in mind, and said: "Suppose I use one tone to represent the first word in this book, two tones to represent the second word, and three tones to represent the third... and so on, Is it possible to deliver a letter?"

Tong Xuan felt his brain groan, and he was dumbfounded!

Yeah, if it's possible, wouldn't it be possible to deliver any message?
Such a function, apart from being unable to speak and listen, is there any difference between it and the phone designed by the emperor?
However, if you think about it carefully, this method also has flaws.

"It is theoretically possible, but the further the character is, the more signals are needed. In order to transmit a word, you need to turn on the switch hundreds of times, or even thousands of times, which is very time-consuming."

Xu Pu nodded, and the two fell into deep thought again.

"Have it!"

Xu Pu's eyes lit up, and he said, "If we represent each word with a set of signals, for example, the first number represents the page number, the second number represents the column, and the third number represents the number of pages. A few, in this case, only a group of six digits is needed!"

Tong Xuan patted his thigh and said, "This method is good, let's try it out now!"

The two people each took a natural encyclopedia as the mother copy of the telegraph, and then went to the transmitter and receiver respectively.

Xu Pu first wrote a sentence, then searched for each word in the book, and recorded it as a number.

Tong Xuan waited for a long time, and suddenly heard a crackling sound, and started to receive the report.

He hurriedly took out his pen to record, so he quickly picked up the pen and wrote down an eight, a five, and a nineteen.

Finally, the vibration of the transceiver stopped, Tong Xuan looked at his injuries, and recorded five sets of numbers, each set of six.

Immediately afterwards, I opened the Encyclopedia of Nature and muttered: "Page eighth, column five, No. 19 characters... Well, this is a Chinese character."

Next, translate the second, third, fourth, and fifth characters, and then write these five characters on paper:
What to eat for lunch

Tong Xuan laughed and said, "It's really wonderful!"

At this time, Xu Pu stepped forward, looked at Tong Xuan's record, nodded and said: "Fortunately, the task arranged by the emperor has finally succeeded today!"

Tong Xuan said again: "You still need to improve on this, otherwise, I can only accept it, which means I can only listen and not speak."

"This is easy to handle. You only need to add the sending function to the machine receiving the signal, which is the same as the one on my side."

When Xu Pu manufactured the ticker, he only wanted to verify whether the signal could be transmitted successfully, so he simplified the configuration and only used it for reception.

Tong Xuan said: "It's not too late, let's do it now!"

After a while, the telegraph receiver was modified and turned into a telegraph transmitter.

The two came to two places again, and this time, Tong Xuan started sending the report.

After Xu Pu received the number, he translated it into five words:

What do you want to eat

He thought for a while and replied two words.

After Tong Xuan translated these two words, his face suddenly turned dark.

"eat fish"
