For science and technology, Hong Xuanjiao is a lot of nobles on the one hand, and has no time to dabble, on the other hand, she is older, and she has missed the best opportunity to learn, and objectively speaking, women's talent in mathematics, physics and chemistry is indeed inferior to that of men, so in addition to military-related, she knows nothing about mathematical knowledge, but not understanding does not mean that she is not curious, she wants to know what Wang Feng spent a lot of money to raise a group of people to specialize.

"Sister Xuanjiao, don't worry!" Sheng Xuanhuai nodded with confidence and ran out.

Zhang hurriedly called: "Hey, it's going to be dinner soon, where are you going?" ”

Sheng Xuanhuai shouted without looking back: "Grandmother, I only have two days, I'll see what materials are missing at home first, no, I have to go back to Suzhou tonight!" ”

In the blink of an eye, Sheng Xuanhuai had disappeared without a trace, and Zhang was stunned for a while, and only after a long time did he say helplessly: "Commander Wang, it's not the old woman who said you, look at Xuanhuai, how old is it, there's no need to treat people as cattle and horses, right?" ”

Wang Feng smiled and said: "Old lady, I don't dare to be harsh with what you say, as the saying goes, the young don't work hard, the boss is sad, now it's not bitter or tired, eating and drinking is very fast, but when you are old, you will eat up and drink all the family property, and it's too late to think about being tired. Sheng Xuanhuai is a little bitter now, but he is laying the foundation for the future. ”

Sheng Long took it over and said, "Commander Wang is right, Xuanhuai was taken away in May last year, and it's only been a few months?" Judging the two of them, they have become capable and neat, and the contrast between the front and back is so great that I almost dare not admit it.

This man. Just can't be too comfortable, the plaything lost sage has already pointed out. I think Xuanhuai will be able to be the pillar of our Sheng family in the future, but. More than 20 brothers and sisters can't all point to him, you little guys, go to Suzhou with Commander Wang on the sixth day of the Lunar New Year, and learn something, huh? ”

"Oh~~ That's great!" The children are happy, learning knowledge, and revitalizing the family, and there are no long-term plans for the time being, but they are deeply impressed by the prosperity of Suzhou. To live in a glittering metropolis, who wants to stay in the countryside and live a hard life? Even small children are no exception.

Zhang hesitated: "This is not good, it is right to learn something from Commander Wang, but how can I do it if I don't stay with anyone?" ”

"Eh~~" Sheng Long waved his hand and said, "I know you are reluctant to have children, so who do you say you will keep?" Whoever stays is harming him, what can he do by squatting in the countryside and guarding the fields? It's not a bad thing to go out and see the world.

Since Commander Wang became the ruler of Su Song, changes have been happening every day, and the changes in the world have never been so dazzling. The world has changed, if you don't learn new knowledge and broaden your horizons, you can only be a rich man in the countryside for the rest of your life. Of course, my generation ploughs the fields and reads. It's been a lifelong paste, but the children can't. They're too young to be confused. If you really don't make it, come back and farm! ”

Wang Feng and Hong Xuanjiao exchanged surprised looks, both surprised that Sheng Long, a rich man in the countryside, could have such a profound insight.

Sheng Long couldn't help but smile proudly: "Commander Wang and Deputy Commander Hong don't be surprised, although I am a little older, but I am not pedantic, by the way, you just said that you want me to participate in the study of that telegram, but I don't know anything, and my age is indeed here, learning new knowledge is not as good as a child, I am not unwilling, but I am worried that something will go wrong!" ”

Wang Feng waved his hand and said, "Elder Sheng is too worried, let me first tell you what the telegram is about"

Wang Feng introduced the principle and working mechanism of the telegraph in detail, and said at the end: "In the end, the telegraph actually transmits Arabic numerals, neither Chinese nor English can be transmitted directly, so we need to correspond to the text, I mean, between 0000 and 9999, each group of numbers corresponds to a Chinese character, I named it the standard code."

For example, I, we are tentatively set at 0000, I sent you a telegram in Suzhou, and the one sent was 0000, and what you received was also 0000, but through guò standard code comparison, you can restore 0000 to me, the same reason, a sentence and a paragraph of text can be compared with the standard code.

This is a milestone change in the history of human communication, and for example, if you write a letter to Sheng Xuanhuai in Suzhou, it will take two days to receive it at the earliest, but if the telegram is sent through guò, you send it at the time, and the post office in Suzhou will receive it at that time, and then notify Xuanhuai to pick it up, no more than a day before and after, this is still less than 200 miles from Suzhou to Changzhou, if it is Nanjing to Beijing, Shanghai to Xi'an, how much time can be saved? In the future, if we build a nationwide telegraph network, how much convenience will it bring? This is the great impact that science and technology have on human life. ”

"Oh~~" Sheng Long suddenly realized: "The old man understands, although I don't understand the telegram, but it is not a problem to compile a standard code list, okay, I took this job, when does Commander Wang need to use it?" ”

As the so-called difficult people will not, those who will will not be difficult, Wang Feng explained the telegram in a simple and easy to understand way, and everyone in the hall, including the children who are a few years old, showed a clear look.

Wang Feng muttered: "At present, the telegraph is still in the development stage, and it will take about two to three years from laying the line to the trial operation. Foreigners have the habit of naming their inventions after the inventors, and we also name the standard code as Shenglong code, how about it? ”

"Hahahaha~~" Sheng Long suddenly laughed and said: "I didn't expect the old man to be able to stay for eternity, thank you Commander Wang, but isn't these three years too long?" I don't even have a word a day, according to the old man, a month is enough! ”

Originally, the Zhang family was relieved to hear Wang Feng's three-year appointment, thinking that Wang Feng finally treated people as human beings, but his wife didn't know what to do, and boasted that it would be completed in a month, isn't this cheap? But the seven orifices that made her angry immediately glared at her, and said dissatisfiedly: "You old guy is full of food, aren't you?" Commander Wang said that three years is three years, and you are less capable! ”

"Hehe~~" Sheng Long smiled and didn't squeak, at this time, a housekeeper outside hurriedly ran in and shouted excitedly: "Master, master, old lady, the eldest young master is back with his wife!" ”

"Oh?" Sheng Long stood up, this is really joyful, the eldest young master is his eldest son Sheng Kang, and he is also the father of Sheng Xuanhuai and Sheng Xuanmei, who is the governor of Hubei and is loyal to his duties, and has not returned home for two or three years.

Zhang hurriedly pulled him: "Sit down, his old son is almost sick, it's normal to come back!" ”

Sheng Long remembered the letter he had written, and sat back down.

Outside the house, a man and a woman were full of anxiety, supporting each other and trotting, all of them were in their thirties, the man's face was more similar to Sheng Long's, the face of the Chinese character, and the woman's eyebrows were delicate, and Sheng Xuanmei was like a mold cast, this is Sheng Kang's wife Liu.

When they ran into the house out of breath, the couple instantly had a feeling of going back to the wrong home, both men and women, wearing miscellaneous clothes, both Chinese and Western, among which men, including the old father Sheng Long, all had short hair, and there were several unfamiliar men and women at the table.

What's even worse is that my father is full of red and radiant, how can he look a little sick?

Is it a return to the light? An extremely terrible thought flashed into his mind, Sheng Kang glanced at his wife, and read the same worry in his wife's eyes, and at the moment, regardless of the rest, he grabbed his wife, flew to the seat, and cried loudly: "Father, Kang'er is back, fortunately in time, Kang'er is not filial, and he almost can't see his father." ”

"Huh?" The old couple were a little puzzled, exchanging a puzzled look, in their impression, this eldest son is calm, known as Mount Tai collapsed in front of him and his color remained unchanged, but how could he lose his temper so much? It wasn't like this last time I went home, and Zhang couldn't help but ask, "You guys got up and talked, are you in danger on the road?" ”

The couple knelt straight, Liu wiped his tears, Sheng Kang shook his head and said: "Mother, you are too worried, because of the supervision of food affairs, the situation is urgent, so it has been delayed for a while, and because of the bandits, the Yangtze River waterway is not passable, and you need to take a detour, and only now I have returned home, there is no trouble on this way, but have you asked a famous doctor for diagnosis and treatment?" How is your body? ”

"Eh~~ What famous doctor do I invite? I'm so good! Sheng Long waved his hand violently: "Don't kneel, just come back safely." ”

"Father, you can't be careless, you have to give it a try anyway!" Sheng Kang shouted anxiously.

"Kang'er, what exactly do you want to say?" Zhang was puzzled.

"This" Neither of the husband and wife can speak, after all, children have to pay attention to the problem of avoiding in front of their parents.

The atmosphere in the room was a little weird, and the children didn't dare to come forward to salute, "Hahahaha~~" Wang Feng suddenly laughed and said: "Elder Sheng, I understand, Ling Lang thought you were dying, and regarded you as a return to the light, you can't leave too early, you haven't done what you promised me!" ”

Sheng Long suddenly realized, and waved his hand again with a smile: "You free cub, curse your old son to die, get up quickly, I'm fine, I don't have any illness!" ”

Sheng Kang asked with some disbelief: "Didn't you write to say that you are seriously ill and asked Kang'er and his wife to come back as much as possible?" ”

Zhang reluctantly took it and said, "Don't say that your father is not good, how can you go home?" I have business to tell you now, you come first. ”

"Oh!" The husband and wife were confused, they both stood up, Sheng Xuanmei hurriedly stepped forward and gave a salute happily: "Xuanmei greets her father." Then he threw himself into Liu's arms and writhed coquettishly.

"Uncle, aunt is good!" The children also greeted each other, and the couple greeted each other with stiff smiles. (To be continued......) R1292
