In April, the Forbidden City is full of flowers and green willows, and the morning is cool.

The wind is light and the clouds are light. Under the deep and distant blue sky, the rising red sun shines on the yellow glazed tiles in the palace, shining brightly and dazzlingly.

In front of the Ganqing Gate, the eunuchs lowered their heads to clean the palace roads and made rustling sounds.

"Father!"

"Father!"

A burst of rapid shouts came into the Ganqing Gate, followed by a young man in his early twenties.

The young man had a handsome face, but his hair was disheveled and his hair was unkempt. Even the prince's regular clothes with four balls of Panlong embroidered with dirty clothes.

The eunuch on duty hurriedly stepped forward to stop him: "Your Highness, King Jin, please keep your mouth shut, this is the Ganqing Palace."

"Father!"

King Zhu Heying of Jin pushed away the eunuch on duty, and with unconcealed excitement on his tired face, he quickly broke into the Ganqing Palace.

"Your Highness, King of Jin!"

The eunuchs on duty were shocked, put down their sweeping tools and hurried over to stop them.

If this King of Jin had not come alone, everyone would have thought he was leading troops to force the palace! It was probably the alarm bell would have been directly sounded.

At this moment, the door of the Ganqing palace slowly opened, and an old eunuch in a python robe appeared in front of the door.

The old eunuch had gray hair and a gloomy face. When he saw King Zhu Heying of Jin, he immediately showed a kind side and said in harmony: "Prince Jin, what are you doing?"

"Parent Wu, I want to see my father, and I have a great joy!"

As he said that, Zhu Heying had no time to explain, so he walked around Wu Zhong and flashed into the hall.

Wu Zhong showed a smile on his face and shook his head with a smile. It was obvious that he had no choice but to deal with His Highness King Jin.

King Zhu Heying of Jin was the second legitimate son of Emperor Zhu and Empress Xu. He was the most filial among the princes and was also loved by the emperor and empress since childhood.

Zhu Heying was extremely passionate about scientific research and made some achievements in many fields at a young age. For this reason, Zhu Cixuan gave him the Jiuwu Feilong Hall in the northwest corner of the palace and used it as a laboratory for him.

Wu Zhong knew that Prince Jin was not a person who did not understand the rules. He said that if there was a big happy thing, he must have developed something good.

In the hall, Zhu Cilang, who was nearly fifty years old, was half lying in front of the Dragon Case, looking carefully at a detailed map of Tsarist Russia, and circled dots on the map from time to time with a red pen.

King Zhu Heying of Jin walked very quickly, and he leaned over and saluted from afar: "My son respectfully asks the father and the emperor for peace!"

Zhu Ciyang raised his head, his sharp eyes gradually became gentle, and he waved to Zhu Heyan, saying, "Yan'er, did you not have a rest last night? Is this what you look like?"

At this time, Zhu Heying was disheveled and had no image of a prince. Even her eyes were darkened, and she obviously had been staying up all night.

This situation has not been the case once or twice. There have been court officials who have long disliked the letter to impeach King Jin, calling him a nobleman who is ignorant of etiquette and demeanor and does not do his job properly, which is really a disgrace to the status of the royal family!

Of course, such impeachment is basically useless. Zhu and Yan are just King Jin and have no position in the court. Like an unemployed vagrant, what can you impeach him? Removing the title of king? This is not realistic!

At most, the emperor issued an order to scold him, and even the most serious thing was that he was imprisoned in the sect's mansion for a period of time.

However, Zhu Cixuan never punished Zhu Heying. In his eyes, the fourth brother is a genius! Especially in the study of electricity!

Sure enough, Zhu Laosi was startled by the moment he spoke.

"Father! The telegram experiment of the son minister was successful!"

"What? Have you sent a telegram?" Zhu Cixuan was shocked.

Zhu Heying solemnly said: "Yes, my father, after a day and night of experiments, Erchen found that the attraction of charged objects acting on each other, and the same law as the universal gravity discovered by Master Niu! They can be converted into electrical signals, Erchen thought of a way to record them!"

As he said that, Zhu Heying's face turned slightly red with excitement: "Father! You said it well at the beginning. There are really messengers in this world who are faster than the eight hundred miles of speed up!"

One summer fifteen years ago, in the pavilion of the palace and the palace, Zhu Heying, the six-year-old King of Jin, snuggled in his father's arms.

At that time, they saw a meteor passing through the sky, and Zhu Hejian asked, "Father, I heard from the masters that the Ming Dynasty is vast and is thousands of miles away from east to west. If the meteor sends a message to the frontier, will it be faster than the 800 miles?"

Zhu Cilang touched Zhu Heying's little head and said, "Meteor is fast, but it cannot deliver messages. There are many things in this world that are faster than the eight hundred miles, such as telegrams, emails, and mobile phone text messages."

"What is telegram? What is email? Are they fast?"

"Their speed is as fast as flashes. No matter how far away, you just need to finish writing the letter and send it out, and the other side will receive it immediately, in just a blink of an eye."

"So fast! Then where are they?"

"We are not smart enough to find them yet."

This childhood conversation, as well as the names such as "telegram" and "email" mentioned by Emperor Zhu, have always been hidden deep in the hearts of King Zhu and Yan, of Jin. He vowed to find them, let them convey messages to the Ming Dynasty, and let their father get news from the frontier as soon as possible.

Now, Zhu Heying finally found the guy named "Telecom"!

Looking at his father's surprise gaze, Zhu Heying felt even more satisfied. This was his "alternative manifestation" of filial piety. He used his own abilities to solve his father's problems.

"Zhan'er! Tell me how you did it?"

Zhu Cilang looked solemn and wanted to make sure that telegram was really important to him and the Ming Dynasty!

At present, the communication methods of the Ming Dynasty are mainly about post delivery, pigeons, dogs, fast ships, and beacons.

Post delivery is a specialized person who takes horses or other means of transportation to deliver letters to the destination, similar to express delivery and takeout in the 21st century.

However, it would cost a lot to establish a reliable and fast delivery system on the vast land!

Not only should a good road network be established, but appropriate station facilities must also be equipped with horses and trains, which are very difficult in the northwest region where transportation is inconvenient.

Pigeon communication is very low in reliability and is easily restricted by weather and paths.

Using beacon smoke and lights that are visible to the naked eye is an old-fashioned way. It is too difficult, and it is also expensive and susceptible to weather and terrain.

In Zhu Cilang's eyes, these communication speeds were unbearable and slow, which seriously reduced his confidence in unifying the world.

For decades, Zhu Cixuan has been thinking hard about the principle of telegraph and wants to make this thing out, but he knows nothing about electricity and has no idea how to start!

Now, the fourth son, King Jin, actually invented the telegram! This is simply a qualitative change across the era!

Therefore, he was eager to know how far the thing that the invented by the fourth brother was and whether it could be put into production and use?

The cost of establishing a telegraph bureau and laying cables, manpower, material resources, etc. are all small matters. As long as the technology is mature, he will continue with his will and the whole country will do it immediately!

Seeing that his beloved father looked expectant, Zhu Heying said excitedly: "I used static electricity experiments to send telegrams. Last night, Erchen and his assistants used forty wires to represent different Chinese characters. Then they added static electricity to the wires in the order of text. The receiving party connected the corresponding small paper strips to each wire. When the paper strips rise due to static electricity, they can copy the text in order!"

Zhu Heying talked in detail for a long time and gestured from time to time, but he was about to prepare for an experiment in the Ganqing Palace.

He became more and more excited as he spoke: "Father, the son minister, planned to refer to the radical arrangement method of the "Tianwu Dictionary", and selected thousands of commonly used Chinese characters and compiled a Chinese character codebook!"

"Okay! OK! OK!"

Looking at the unkempt fourth son, Zhu Cilang patted his shoulder heavily, and said that the three wins were good.

At the same time, he felt a little regretful.
Chapter completed!
