The Jin Yiwei received the order and all evacuated from the palace.
A thrilling poisoning case went unsolved, and the haze shrouding the Forbidden City quietly dissipated.
When Yuan Bin learned about this result, he was extremely confused.
To poison the emperor, at least nine tribes must start.
However, the main culprit who was discovered after a lot of effort turned out to be the current crown prince...
To be precise, there is also the second prince and the third prince. These three brothers committed the crime in a gang.
If this kind of thing happened in the Yongle Dynasty, it would be serious.
Emperor Taizong was already forty years old when he launched an army to quell the crisis. He had been emperor for twenty-one years. His three sons had grown up, and each of them was able to take charge of his own affairs. The battle for the throne was extremely fierce.
Regardless of whether he is the prince, the king of Han or the king of Zhao, or even a good grandson, whoever dares to poison Emperor Taizong will never survive.
The current situation is quite different. The prince is only eight years old, and the other two accomplices are six years old and four years old.
Is it too early to say that this prince wants to drive me out early and come to power himself?
What's more, two princes are also present. We really need to investigate who will pass the throne to the three brothers after they play together...
Yuan Bin had no choice, so he simply removed all the royal guards and pretended that nothing had happened.
As for what kind of punishment the prince and the two princes will receive, that is the emperor's family matter and has nothing to do with him.
Everything in the palace was restored to its original state, but there were rumors that that day, a heartbreaking cry came from the East Palace.
There seems to be more than one person speaking, there seem to be two or three...
After several days of recovery, Zhu Qizhen was finally able to get out of bed and walk.
During this period, Queen Mother Sun occasionally came over to visit. On weekdays, Queen Qian and Wan Zhen'er were taking care of her at the bedside.
The Imperial Hospital came to see him and prescribed some decoctions for recovery, but Zhu Qizhen didn't look good on them.
Empress Qian had already told the truth about the situation at that time. After arriving at the Imperial Hospital, she immediately made the decision to die.
If it weren't for Wan Zhen'er's desperate efforts to save her, she would have really collapsed at that time.
Zhu Qizhen has long wanted to rectify Taiyuan Hospital, and now he is even more determined to make changes, and big changes!
Hereditary medicine, this medical book, that allusion, all are torn down and started again!
At the same time, he himself was feeling very sad. Despite the strong winds and waves, he almost lost his life because of a bowl of fish soup given by the three filial sons.
Looking back, life is really unpredictable!
Concubine Zhou Guifei and Concubine Wan Huan had already come to confess their crimes. They were also very frightened that such a big thing had happened.
But, so what?
Zhu Qizhen did not hold them accountable. He also blamed himself for this. He didn't look carefully when he was drinking fish soup, and there was actually puffer fish!
The person who deserves the most blame is Tong Xuan. This guy doesn't do research every day and just thinks about how to electrocute fish.
If you want to eat fish, there are a lot of them on the street. If I allocate so much silver to you, I will develop an electric fish device. Do you have a grudge against fish?
When Beilin learned the whole story, she was extremely frightened.
If Wan Zhen'er hadn't rescued him in time, the emperor would have died, and the sky would have collapsed!
At that moment, he set a rule at the Academy of Sciences that no one was allowed to study equipment related to electric fish, and even fishing, netting and other small things were not allowed.
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 continuing.
After doing all this, I still felt uneasy. After thinking about it, I also issued a rectification notice to Xu Pu’s telephone research team.
Xu Pu was completely confused. He wanted to ask what happened, but the reply he got was... Who asked you to study electricity?
As a result, two electricity-related laboratories of the Academy of Sciences were shut down at the same time for rectification.
All researchers are not allowed to leave the Xishan base without authorization, and they have nothing to do, so they can only go back to the cottage and sleep.
Tong Xuan and Xu Pu had special identities and were temporarily isolated in a warehouse, waiting for the verification results.
The two of them had nothing to do in the warehouse and could only chat casually.
However, all the conversations we talked about were related to electricity. No matter what topic we talked about, we had to return to electricity in the end.
Seeing Tong Xuan sighing repeatedly, Xu Pu comforted him: "His Royal Highness also had good intentions and did something wrong. This has nothing to do with the results of your research. Don't blame yourself too much."
Tong Xuan didn't know it, but the whole thing was caused by himself, so it was impossible not to blame himself.
"Your Highness is afraid that he will be beaten."
Xu Pu said: "Your Highness is still young. If you are beaten, just take it. It will be fine."
"I'm not worried about His Highness getting beaten, the main thing is..."
Tong Xuan thought for a while and continued: "You may not know that His Highness is very interested in electricity and has a good talent. I am worried that he will be affected by this incident and will not dare to contact electricity again. Isn't it a pity?
"
Xu Pu laughed and said: "What did Brother Tong say? His Highness is the crown prince and will inherit the throne in the future. Even if he is interested in electricity and has good talent, how can he study electricity all his life like ordinary people?"
Tong Xuan laughed dumbly and said, "I'm being narrow-minded... By the way, how's your phone call going?"
Xu Pu shook his head and said: "It's difficult to have no breakthrough for such a long time."
"Is there something wrong with the research direction?"
"The direction was set by the Emperor himself, so there shouldn't be any problems. The key now is materials. Many things simply cannot meet expectations. For just one component, hundreds of materials have to be tried. It's difficult!"
Tong Xuan asked again: "Have you ever thought about making a simple model machine first?"
"simple……"
Xu Pu suddenly froze and murmured: "Yes, why not make it simple?"
This sentence gave him great inspiration. After getting the drawings, he focused 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 simplify it, for example..."
Xu Pu became interested, found paper and pen, and started drawing.
"According to the drawings given by the emperor, the telephone is used to transmit sounds. As long as the lines are connected, theoretically, two people can have a conversation even though they are thousands of miles apart."
"I have studied carefully and found that the principle of the telephone is different from that of the microphone. The microphone transmits sound directly, 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 difficult to pronounce, and I am afraid only Tong Xuan can understand them.
After all, he was the founder of electricity research in the Ming Dynasty. Even if he has never heard of many terms, he can roughly guess them.
Xu Pu became more and more excited as he spoke, and continued: "This is also the problem with the phone, which is the conversion problem between sound and electrical signals. The emperor said that semiconductors are needed. Our team has not yet figured out what semiconductors are, but just now,
What Brother Tong said inspired me a lot!”
"If we give up the conversion between electrical signals and sounds and directly use electrical signals to convey information, can we achieve the same effect?"
Tong Xuan thought for a moment and asked: "How to use electrical signals to transmit messages?"
Xu Pu already had an idea and said: "I'm not sure whether it can 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, "That's enough!"
This is originally the warehouse of the electric power laboratory, where a lot of materials and equipment are stored.
For the new thing Xu Pu just imagined, the things here are enough.
The two chatted for a long time, settled on their ideas, and began to prepare.
First, what you need is a battery.
Tong Xuan has developed a battery that requires zinc rods, sulfuric acid, copper rods, etc., which can be found in warehouses.
This kind of battery is very primitive, because the power is very low, relatively speaking, the cost becomes very high.
Generally, it is only used in laboratories.
The simple telephone that Tong Xuan thought of was not actually called a telephone, but had its own name, called a telegraph.
Whether it's a phone call or a telegram, it's just a name, it doesn't matter.
The two of them worked together to quickly assemble a battery.
Then, Xu Pu found wooden boards, copper wires, iron nails, copper sheets and other materials.
Today's copper wires no longer need to be wrapped with cotton gauze, but rather painted with a layer of paint on the outside. This method is fast and safe.
With everything ready, Xu Pu started assembling.
According to the idea I just thought of, I first took a wooden board and laid it flat, and drove in the long nails until the nails were exposed by two centimeters of the board. Then I fixed the short nails on the wooden boards, connected them with the armature, and then put them on the long nails.
, winding the copper wire, the transmitter became a big boy.
After making the transmitter, he followed the same procedure and assembled a receiver.
The next step was to set up the wires. The warehouse was very large, so the two deliberately stretched the wires. The transmitter and receiver were placed in two opposite corners of the warehouse.
Finally, everything was ready, and the first telegraph machine of the Ming Dynasty was ready.
Xu Pu came to the location of the transmitter and slowly turned it on...
Beep beep beep!
Tong Xuan clearly saw that the electromagnet surrounding the copper wire vibrated and made a sound.
Success!
The two cheered and celebrated the success of the first experiment.
However, a problem arises.
Tong Xuan asked: "How do we confirm the news we want to deliver?"
This thing can't speak and just beeps a few times. What does that mean?
Xu Pu frowned and thought, and said: "It needs to work at a specific time and under specific requirements. For example, when the machine rings, it means there is an enemy attack."
"You mean, use this thing as a beacon?"
"Absolutely."
"How many times did it ring?"
"Three beeps, because I started it three times."
"You mean, every time you start it, it will make a sound?"
"good!"
"In that case...I have an idea!"
"Brother Tong, please speak!"
Tong Xuan felt a flash of inspiration in his mind and said, "Why not use the number of sounds to express a certain meaning?"
"Wonderful!"
Xu Pu clapped his hands and said, "For example, one blast means safety, two blasts indicate enemy attack, and three or four blasts can also have other meanings. Is that good?"
Tong Xuan nodded and said: "Then we need to make a special book to record the meaning of several sounds."
"book……"
Xu Pu's eyes flickered and he saw a book beside him.
Copied casually, it was the earliest published encyclopedia of nature.
Tong Xuan didn't know what he was doing with the book, so he said: "The things in this book are basic and 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 the book, two tones to represent the second word, three tones to represent the third...and so on.
Is it possible to deliver a letter?"
Tong Xuan felt like his head was pounding, and he was completely dumbfounded!
Yes, if it can be achieved, wouldn’t it be possible to deliver any message?
Apart from being unable to speak or listen, what is the difference between such a function and the telephone designed by the emperor?
However, if you think about it carefully, this method also has flaws.
"Theoretically it is possible, but the further the words go, the more signals are needed. In order to transmit a word, you need to repeatedly turn on the switch hundreds of times, or even thousands of times. This is very time-consuming."
Xu Pu nodded, and the two fell into deep thought again.
"Yes!"
Xu Pu's eyes shone brightly and he said: "If we use a set of signals to represent each word, for example, the first number represents the page number, the second number represents the column, and the third number represents the
A few, in this case, you only need a set of six digits, that’s it!”
Tong Xuan slapped his thigh and said: "This method is good, let's try it now!"
The two people each took a natural encyclopedia as the master copy of the telegraph, and then came to the transmitter and receiver respectively.
Xu Pu first wrote a sentence, then looked for it word by word in the book and recorded it into numbers.
Tong Xuan waited for a long time, and suddenly heard a clicking sound, and the telegraph machine started to move.
He quickly took out a 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 injury and recorded five sets of numbers, each set of six.
Then, I opened the Encyclopedia of Nature and muttered: "Page 8, column 5, character 19... Well, this is a Chinese character."
Next, translate the second, third, fourth, and fifth words, and then write these five words on the paper:
What to eat for lunch
Tong Xuan laughed and said, "How wonderful!"
At this time, Xu Pu stepped forward, looked at Tong Xuan's records, nodded and said: "Fortunately, the mission assigned by the emperor was finally successful today!"
Tong Xuan added: "You still need to improve, otherwise, I can only accept it, which means I can only listen but not speak."
"This is easy to do. You just need to add the sending function to the signal receiving machine, just like the one I have over there."
When Xu Pu made the ticker, he just wanted to verify whether the signal could be transmitted successfully, so he simplified the configuration and used it only for reception.
Tong Xuan said: "It's not too late, let's do it now!"
Not long after, the telegraph receiver was modified and turned into a transmitter.
The two of them came to two places again, and this time, Tong Xuan started to send the report.
After Xu Pu received the numbers, he translated them into five words:
What do you want to eat
He thought for a while and replied with two words.
Tong Xuan translated these two words, and his face suddenly turned dark.
