Cloudless, under the clear sky, a large group of pigeons fly around the lakeside manor "servant", this is the pigeon raised by the Duke of Yiguo, the scale is magnificent, together with a large area of lake scenery, has become a beautiful scenery outside Xiyang City.

Everyone knows that the Duke of Yi is fond of pigeon meat, and the various practices of suckling pigeons and pigeon eggs are also one of the dishes of Wuwei Zhai under his name, so outsiders are accustomed to such a large flock of pigeons here.

In the open space outside the pigeon loft, Yu Wenwen is feeding the pigeons with his children, the little ones are cheering, holding pigeon food and sprinkling, all around are "cooing", and the pigeons of different colors fall to the ground and surround them.

Yu Wenwen took his family to live in Lakeside Manor for a few days, and originally wanted to bring his cousin (nephew) Yu Wenli and brother-in-law Xiao Yu to come over, but the two of them happened to be "teaming" and debating with their friend Kong Yingda in the state school these days, so they didn't go together.

said that he lived for a few days, but he didn't want to go back, especially the little guys, the three youngest stayed in the mansion, and were led by Wei Chi Chifan, who stayed in the mansion, and the first four big ones were happy in the manor.

The mansion in the city is a bit like a cage to them, and the lakeside manor is the interesting place, so it seems that the original stay for a few days will have to be extended for a while.

Yu Wenwen shoulders the heavy responsibility of parent-child, and he can't leave his official duties, so even here, he is busy from day to night, playing with his children, handling affairs, and having to "pay public food" at night.

After paying the public grain, he had to "add an hour", get up early the next morning and go back to the city to "work" at the official office, and come back in the afternoon to continue to play with his children, so he was very busy.

Feeding the pigeons is very pleasant, but the pigeon feces is not so pleasant, Yu Wenwen wiped off a bubble of pigeon feces on his face, looking at this large group of his own efforts, instead of being annoyed but very pleased.

Before modern times, long-distance communication has always been a problem, and carrier pigeons are barely usable, so Yuwen Wen spent blood to breed and breed carrier pigeons, and it has been six years so far, and the results are remarkable.

After generations of screening, he got a carrier pigeon that can fly thousands of miles stably, and now there are more and more carrier pigeons that can fly back to Xiyang from Yecheng, bringing him all kinds of information about Yecheng thousands of miles away.

Flying pigeons can pass on books, not many people know in this era, so in order to hide people's eyes, he simply raised a large number of pigeons, carrier pigeons, meat pigeons mixed together, even if it is a "pigeon meat" reputation.

"Ayya! The pigeon food is gone! ”

"Huh? Ah, Aye, here, here..."

The family was having a good time, a servant came to the neighborhood to wait, and stood without saying a word, Yang Lihua saw this and knew that this person had something to report to Yuwen Wen, and hurriedly took the little ones to play with Xiao Jiuniang.

Yu Wenwen walked towards the villa, the man followed closely, and after coming to the study, he began to report to Yu Wenwen.

He was in charge of the "telegraph" group, and the related work of the group was at the forefront of the government, and its "secret level" was among the highest in the government, and it was directly directed by Yu Wenwen, the lord of Lang.

Battery, electromagnet, copper wire/iron wire, with these three things, under the guidance of Yu Wenwen, they finally realized the initial technical idea, but there is still a lot of work to follow.

"How's the telegraph experiment?"

"Lord Huilang, I have tried it, there is no problem, and now everyone is practicing sending reports."

When the man said this, he held up a pamphlet: "Lord Lang, the comparison table of the telegram has been compiled, please take a look." ”

Yu Wenwen took the booklet and looked through it carefully, which was the key to the telegraph's message, which could "transmit" words from one end of the wire to the other through an electric current.

There are thousands of commonly used Chinese characters, and it is impossible to transmit them through the keys of the telegraph, so they need to be converted by encoding.

The electric key transmits information, the most basic elements are only dots, strokes, and then according to the combination to represent different corresponding information, that is, "telegram code", Yu Wenwen refers to the principle of Chinese characters in that era, and lets his subordinates copy out.

Take his name as an example: Yu, numeric code 1111; text, numeric code 1112; Wen, numeric code 1113.

The telegram code is encoded with dots and crossed numbers "1" to "9" and "0", and this group of numbers is sent when the telegram is sent, and then the receiver "translates" the corresponding words according to this group of numbers according to the Chinese character telegram comparison code.

"Well done, let them practice more." Yu Wenwen put away the small notebook, which was handed over to him for "archiving".

"The experiment of the telegraph, step by step, according to the plan, does not seek speed, but seeks stability."

Yu Wenwen inquired in detail about the situation of the telegram team, and after he retreated, he fell into deep thought alone.

The biggest problem is the homing habit of the pigeon, in short, to use the pigeon to transmit the message to a place, the nest of the carrier pigeon must be in this place.

This means that the pigeon has to live in the destination for a long time, otherwise it will not be able to use its homing habits to send messages.

Yuwenwen is in Xiyang City, and if he wants to use flying pigeons to send letters to Yecheng, he must have carrier pigeons that grew up in Yecheng, so to achieve this purpose, he must raise pigeons in Yecheng.

Raising a group of pigeons in one place can be interpreted as "eating pigeon meat", but raising a group or several groups of pigeons in other places, and then interpreting it as "eating pigeon meat" is to cover your ears and steal the bell.

Those who have a heart can guess that there must be something strange in it, Yuwenwen wants to keep the flying pigeon pass a secret as much as possible, so the breeding place of the carrier pigeon is quite limited.

To fly pigeons to Xiyang somewhere, you have to take the carrier pigeon from Xiyang to the past, after the carrier pigeon is used up, you have to come to Xiyang to get the pigeon, the timeliness is a little poor, not to mention that the pigeon will have various accidents on the way, so at least double backup, more than two at a time.

It was a bit of a hassle, but it was barely useful, but once he moved on to another job, the flock of pigeons he had worked so hard to raise was wasted, and he had to hatch the next generation to grow up in a new place.

If there is a problem, we have to find a way to solve it, why don't we simply open our brains to engage in a black technology and have a wireless communication?

If you can't figure it out, you don't need to talk about it, wireless communication seems to be a simple principle, but in fact he doesn't have that level of technology at all, not to mention wireless telephone, even wireless telegraphy can't be made.

So Yuwenwen retreated this time, trying to click on the technology tree of "Cable Telegraph".

The telegraph made it possible to communicate reliably over long distances, even if it was wired telegraph, which was an artifact in this era, a device that only appeared in the 19th century, and it was a black technology in this era.

In ancient times, no matter whether it was Chinese or foreign, no matter how large the empire was, there was a limit, that is, distance.

Too far away, so that the central government's orders can not be transmitted to the frontier in time, the mountain is high and the emperor is far away, and the feudal officials are self-unified, in fact, they are no different from independent kingdoms, and the flying pigeon biography may be useful, but it is still a drop in the bucket.

If we can solve the problem of transmitting information over long distances, we can break through the traditional boundaries of territory.

Now that there is a cable telegraph, then Yuwenwen can open the power of the flood and walk to the pinnacle of life?

The ideal is very plump, the reality is very skinny, and if the telegraph wants to be practical, it must first solve the practical technical problem: can multiple points receive the telegram on the same wire?

If it is only a telegraph between the two ends of the start and end, then the practicality will be greatly reduced, and how to solve this problem, Yuwenwen does not know, so it is necessary to continue to study.

A year? Five years? Decade? God knows when it will come out.

And the other problem is the cost, the line with the wire telegraph costs the cost, and the maintenance of the line is more expensive, the longer the line, the higher the associated costs, which he can not afford on his own.

The central government needed cable telegraphs, which could effectively strengthen local control, and Yu Wenwen, as a magistrate, now promoted the telegraph as a cocoon: it was no different from putting a noose around his own neck.

There is no telegram, and the emperor can be far away, and the general will not be subject to the orders of the monarch outside, with the telegram, ask for instructions early and late, and if you don't want to move a building of soldiers and horses, you have to ask for instructions, and you have no chance to pretend to be crazy and stupid, just like the little daughter-in-law who is managed by her mother-in-law.

However, if one day the daughter-in-law becomes a mother-in-law, it will be different! (To be continued.) )
