There is no cloudless, and under the clear sky, a large group of doves flew around the lakeside manor "seriously" around the lakeside manor. It is a pigeon raised by Duke Zhu's mansion. Its scale is spectacular. Together with the large lake view, it has become a beautiful scenery outside Xiyang City.

Everyone knows that Duke Wu is fond of pigeon meat, and the various ways of making pigeons and pigeon eggs are also one of the dishes of Wuweizhai under his name, so outsiders are accustomed to such a large group of pigeons here.

In the open space outside the pigeon loft, Yuwen Wen was taking his children to feed the pigeons. The little guys cheered and kept sprinkling pigeon food. There were "cuckoo" sounds all around, and pigeons of different colors fell on the ground and surrounded them.

Yuwen Wen brought his family to the lakeside manor for a few days. He originally wanted to bring his cousin (nephew) Yuwen Li and his brother-in-law Xiao R to come together, but the two of them happened to be studying "grouping" to debate with their friend Kong Yingda in the state these days, so they did not travel.

He said he stayed for a few days, but he didn't want to go back after he lived there, especially the little guys. The three youngest ones stayed in the mansion, led by Yuchi Chifan, who stayed behind the mansion, and the four big ones in front were having a lot of fun in the manor.

For them,

It's a bit like a cage, and the lakeside manor is the interesting place, so I originally planned to stay for a few days, but it seems that I have to extend it for a while.

Yuwen Wen is responsible for the heavy responsibility of parent-child, and cannot give up official duties, so even here, he is busy from day to night, playing with his children and handling affairs, and has to "hand over public grain" at night.

After handing over the public food, he had to "add one clock". He got up early the next morning and went back to the city to "work" at the government office. He came back in the afternoon and continued to play with his children, so he was very busy.

Feeding pigeons is very comfortable, but it is not so comfortable to cover your face with pigeon shit. Yuwen Wen wiped off a bubble of pigeon shit on his face. Looking at the large group of his efforts, he was not angry but very relieved.

Before modern times, long-distance communication has always been a problem, and carrier pigeons are barely useful, so Yuwen Wen spent a lot of money to breed and breed carrier pigeons. It has been six years since then, and has achieved remarkable results.

Through generations of screening, we have obtained carrier pigeons that can fly thousands of miles steadily. Now more and more carrier pigeons can fly from Yecheng back to Xiyang, bringing him various information about Yecheng thousands of miles away.

Not many people know about the ability to pass on letters in this era, so in order to cover up, he simply raised a large number of pigeons, carrier pigeons and meat pigeons, and even if he was a reputation of "eating pigeon meat".

"Aye! The pigeon food is gone!"

"Ah? Ah, there is here, there..."

While the family was having fun, a famous servant came to the nearby waiting, stood up and said nothing. When Yang Lihua saw this, she knew that there was something wrong with this person and reported to Yuwen Wen, and quickly took the little guys to the side with Xiao Jiuniang to play.

Yuwen Wen walked towards the villa, and the man followed closely. After coming to the study, he began to report to Yuwen Wen.

He is in charge of the "Telecommunication" group, and the relevant work that the group is engaged in is the top in the mansion and is directly guided by the Langzhu Yuwen Wen.

Batteries, electromagnets, copper wires/iron wires, with these three things, under the guidance of Yu Wenwen, they finally realized their technical concepts initially, but there is still a lot of work to do next.

"How was the telegram experiment?"

"Master Huilang, I have tried it, there is no problem. Now everyone is practicing sending newspapers."

When the man said this, he brought up a booklet: "Master, the comparison table of the telegram has been compiled, please check it out."

Yu Wenwen took the booklet and looked carefully. This was the key to telegrams transmitting information, and could "transmit" words from one end of the wire to the other end.

There are thousands of commonly used Chinese characters, and it is impossible to transmit them through the telegram keys, so it needs to be converted using encoding.

When the electric key transmits information, the most basic element is dots and strokes, and then different corresponding information are represented according to the combination, that is, "telecommunication code". Yuwen Wen referred to the Chinese character telegram code principle of that era and asked his subordinates to copy it.

Take his name as an example: Yu,

Digital code 1111; Text, digital code 1112; Temperature, digital code 1113.

The telegram code uses dots and strokes to encode the numbers "1" to "9" and "0". When sending the telegram, the group of numbers is sent. Then the receiver "translates" the corresponding characters according to the Chinese character telegram comparison code according to the Chinese character telegram comparison code.

"It's done well, let them practice more." Yuwen Wen put away the small notebook, and this was handed over to him for "archive".

"The telegram experiment is done step by step according to the plan, not seeking speed, but seeking stability."

Yuwen Wen asked about the situation of the telegram team in detail. After he stepped down, he fell into deep thought alone.

The problem of using carrier pigeons for long-distance communication is not without them. The biggest problem lies in the pigeon’s habit of returning to the nest. Simply put, if you want to use carrier pigeons to transmit messages to one place, the nest of the carrier pigeon used must be in this place.

In other words, this pigeon must live in its destination for a long time, otherwise it will not be able to use its habit of returning home to deliver letters.

Yuwen Wen was in Xiyang City. If he wanted to use a flying pigeon to deliver letters to Yecheng, he would have to have a pigeon that grew up in Yecheng. Therefore, to achieve this goal, he had to raise pigeons in Yecheng.

Raising a flock of pigeons in one place can be explained as "eating pigeon meat", but raising a group or several flocks of pigeons in other places can be explained as "eating pigeon meat" means stealing the bell.

Anyone with a heart can guess that something is wrong. Yuwen Wen wanted to keep the letters from flying pigeons as confidential as possible, so the breeding areas of carrier pigeons are quite restricted.

To send a letter to Xiyang in a certain place, you must first bring the pigeon from Xiyang. After the pigeon is used up, you have to come to Xiyang to get the pigeons. The timeliness is a bit poor, not to mention that the pigeons will have various accidents on the way, so you must at least double backup and release more than two at a time.

This is a bit troublesome, but it is barely useful, but once he transfers to another place, the flock of pigeons he has worked hard to raise will be invalid and the next generation will be hatched to grow up in a new place.

If you have any problems, you have to find a way to solve them. Why not just start a black technology and wireless communication?

If you can't figure it out, it's free to talk about it. The principle of wireless communication seems to be simple, but in fact he doesn't have that technical level at all. Not to mention wireless phones, he can't even get a wireless telegram.

So Yuwen Wen settled down and tried to click on the "wired telegraph" technology tree.

Telegram makes long-distance reliable communication possible. Even wired telegrams are a magical tool in this era. This is a device that appeared only in the 19th century and is black technology in this era.

In ancient times, no matter how large the vast empires were, they had a limit, that is, distance.

Too far away, the central government's orders cannot be transmitted to the frontier in time. The mountains are high and the emperor is far away. The officials of the border are unified. In fact, there is no difference between them and the independent kingdom. The flying pigeon's letters may be used, but they are still a drop in the bucket.

If the problem of long-distance transmission of information can be solved, it can break through the traditional boundary limits.

Now that there is a cable telegram, Yu Wen Wen can open up the power of the prehistoric world and reach the peak of his life?

Ideals are full, reality is skinny. If telegraphs want to be practical, they must first solve practical technical problems: can multiple points on the same wire be able to receive and transmit telegraphs?

If you just send telegrams between the start and end, then your practicality will be greatly reduced. Yu Wen Wen didn't know how to solve this problem, so you need to keep researching it.

One year, five years, ten years, God knows when to study it.

Another problem is cost. It costs to build a line with a telegraph, and maintaining the smooth flow of this line requires greater costs. The longer the line, the higher the related costs, which is not something he can afford on his own.

The central government needs wired telegrams, which can effectively strengthen local control. Yuwen Wen, as a local official, now promotes telegrams in a cocoon: this is no different from putting a noose around his neck.

Without telegrams, you can still be far away from the emperor. If you are the generals, you will not accept the orders of the emperor outside. With telegrams, you will ask for instructions early and late. If you may not be able to move a war, you will have to ask for instructions even if you want to pretend to be crazy and stupid. Just like a young wife who is under the control of her mother-in-law.
