After the group left, the second dog reported: Fang Jue met with his second uncle first, but he only said a few words of greeting, and after three glasses of wine, he said goodbye, and he had always been in public, and he didn't have a chance to ask the details of the way. It can be regarded as confirming Wang Shihua's speculation.

Wang Shihua thought for a while and asked Uncle Da: "Uncle Da, wait a minute, on the way you take people to salvage the No. 2 ship, ask the brothers, on the way here, has anyone heard the tick-tock announcement?" ”

"Yes!"

Wang Shihua thought for a while, and complained to himself: "It's a pity, we can't understand what the tick-tock telegraph means?" If only I could understand it. ”

The speaker has no intention, but the listener has a heart! Yang Sanfeng's eyes lit up, but he looked around, opened his mouth, and didn't speak.

Wang Shihua felt something, looked back, and saw Yang Sanfeng thinking about things with his head down, thinking that he was thinking about revenge, so he smiled and said: "Sanfeng, don't think about it, it's not that you won't be allowed to go, but it's not time to really do it yet, it's not easy for you to show up in advance, lest the other party be guarded...... Don't worry, I can put my words here, and the day of your revenge is not far away. ”

"Thank you for your care." Yang Sanfeng was a little moved to Wang Shihua and shook his fist, then touched the back of his head, and said with a smile: "Family master, in fact, the little one didn't want to take revenge just now, but has been thinking about the sentence you just said, 'how can I understand the content of the telegram'." ”

Wang Shihua became interested and looked at Yang Sanfeng with a smile.

"Actually, if you want to understand, it's really difficult to speak, but it's also very simple to speak."

Is there such a thing? Wang Shihua's interest increased greatly, and he asked, "What's the difficult method?" Be careful. ”

"If you want to understand, the key lies in the codebook in the dispatcher's hand. The code taken out of the telegram is shot out according to the length and interval of the sound of the telegram, and the receiver writes it down after receiving the code, and then translates it into text against the same code book used by both parties, so that it can be understood. And the difficulty in this matter is how to obtain this codebook? The head of the house, you think that such an important thing as the codebook must be the key protection, and it is difficult for others to take a look, so how can you get it? And I say it simply, because once obtained, it is best to copy the other party's codebook, then, no matter how the other party guards, as long as the telegram is taken according to this codebook, we will know what kind of message they are transmitting. ”

In fact, Wang Shihua also knows a little bit about telegraphs, after all, he has them at home, but he didn't pay much attention to the secrecy work in it before, so naturally it is impossible to pay attention to the codebook. Now hearing Yang Sanfeng say this, Wang Shihua's mood immediately became nervous, and he asked in surprise: "Are you saying that if the code book in the hands of those telegraph operators of my Wang family is seized or copied, any news transmitted by my Wang family through the radio can be easily obtained by the other party?" ”

Yang Sanfeng nodded with a wry smile and said, "Under normal circumstances, this is the case. However, after using the codebook, the average person will wake up after being ambushed by the enemy once or twice, and will immediately change to a new codebook. ”

"That's not going to work either! Not once! ”

"The head of the family, in fact, when I was studying in Wuhan, because of my interest, I learned about this aspect, and I don't know much about it, if you want to ask specifically, you can actually ask a professional dispatcher, they know the tricks best, and I believe there are more preventive means."

Wang Shihua hurriedly shouted to Ergouzi: "Quickly call those two telegraph operators." ”

Taking advantage of this little time, Wang Shihua asked Yang Sanfeng with a smile: "Sanfeng, why did you go to Wuhan to study?" ”

"Two years ago, the Hubei Provincial Government deliberately recruited a group of students in order to prevent ** from rushing into Hubei Province, and planned to expand to various ......units after these people graduated," Yang Sanfeng smiled and said: "My Abba (godfather) spent a lot of money to buy an instructor and get me in. But I was arrogant at the time, and I couldn't get used to the behavior of the instructors inside, especially the attitude and way of doing things that didn't treat the students as human beings, and within two months of entering, I had a conflict with the instructor who taught us marksmanship. As a result, I compared marksmanship with him, and he was not convinced, so he secretly stumbled on me, and I broke a leg in a fit of rage, and then ...... Hey! Hey! Luckily I ran fast, or I would have gone to jail. ”

can make Yang Sanfeng such a clever person have to kill him, you can imagine how bad the instructors did at that time.

Immediately the two telegraph operators came over, and although what they said was more detailed than Yang Sanfeng's, it was roughly the same -- because Wang Shihua used force for the first time to attack the Tian family, after trying all kinds of great benefits brought by the speed and convenience of the telegraph, he attached great importance to the telegraph, and sent a group of students early to study with the two telegraph operators of the Zhang family, and later sent people to study in the Zhongyi Brigade.

Just when the two of them were talking more and more energetically, and when they were about to talk about how to prevent the leakage of telegrams, Wang Shihua interjected decisively with a smile: "After listening to so much, I know the importance of interlacing like mountains...... I'll ask you two about these things later. You go down and have a cup of tea and rest. ”

Then he pulled Uncle Da aside and whispered: "Uncle Da, you also heard clearly about the telegram, right?" ”

"Clear."

"Okay, this time Fang Jue will follow you, and he will definitely bring the radio, when the time comes, I don't care what method you use, as long as you don't alarm them, give me a copy of their codebook. See what I mean? ”

"I see, the head of the house, you are afraid of startling the snakes, so that they will notice it and change the codebook, so that we will not be able to get news from their telegrams in the future. You can't be alarmed, but you have to think about the long term, right? ”

Wang Shihua nodded, and his smiling eyes narrowed into a slit, like a little fox.

Soon, the wine and food were delivered to the Xiao family's fleet, and all the goods had just been unloaded here. After receiving Uncle Jiang's report, after counting, everything was consistent with the list, Wang Shihua hurriedly let all the sailors join the Xiao family's fleet......

After the fleet left, Wang Shihua asked Xiao Renyi to send sailors to drive the seven big ships that needed major repairs to the Xiao family's shipyard to repair them...... Originally, Wang Shihua was very interested in the equipment sent by the province, but now he was full of only two things: one was the telegraph matter, and the other was the Tahu Beach incident and the follow-up matter. Since the latter had no choice but to wait for the progress of the matter for a while, then taking advantage of this opportunity to make the telegraph matter clear would naturally become his greatest concern now.

If you don't say that the family is powerful, it is powerful in three points: sacrifice, patience, and subtlety!

As soon as the seven big ships left, Wang Shihua turned around and left. He was originally impatient to ask by the dock, but in order to be afraid that people would see him attach so much importance to the two telegraphers, he analyzed that he attached great importance to the telegraph - although this probability is pitiful, but he is not afraid of 10,000, he is afraid of what happens, this is the subtlety of the family's work!

When he came to the Wang family's warehouse, Wang Shihua immediately brought the two telegraph operators into the room, and when the door was closed, Wang Shihua personally poured tea for the two of them, and asked with a smile: "Just now you wanted to talk about how to prevent the leakage of the telegram, but I had to stop it for fear that someone would inadvertently leak the tricks inside." ”

"It's because we didn't think it through, so please punish the head of the family."

"Get up! Get up! I'm just mentioning it in passing, you don't have to take it to heart. When the faces of the two returned to normal, Wang Shihua smiled and said, "Now, you two will tell me the tricks in detail." ”

The two immediately complemented each other and talked tirelessly. In order to make Wang Shihua, a layman, more understandable, he gave examples one by one.

An hour and a half later.

After Wang Shihua pondered for a while, Zhengse asked, "To determine who is sending the report, you can hear it from the sender's method of sending the report, right?" ”

"Yes!"

"This is the tracking of people, but the tracking of messages, the fastest is to get the other party's codebook, and the slow is to slowly analyze the other party's codebook according to the actual situation, right?"

"The head of the family is wise, and it is true. However, without the other party's codebook, if you want to analyze the content of the telegram, this is not something that ordinary people can do, and it takes talent. ”

Another added: "It takes not only talent, but also a lot of human and material resources to support this analysis, so that the analyst can judge whether the message is correct or not." ”

"Does my Wang family have talents in this area now?"

After the two glanced at each other, they shook their heads at Wang Shihua.

"Head of the family, this kind of analytical ability is by no means a day's work, and we are incompetent, so we can't do it for the time being."

"Since someone else has such an ability, there must be a way, right?"

"That's right! However, it requires long-term learning and systematic training, coupled with talent, to achieve. ”

Wang Shihua nodded, thought for a while, and said, "Then you go and select a group of people with talent in this field for me, and I will find someone to send them to learn the knowledge of telegraphy." ”

The two ** stood up happily and nodded in thanks.

Wang Shihua smiled and asked the two of them to sit down, and then asked: "If you want to analyze, after all, it will take a while, and it should be much easier to change the code." I'll leave this matter to the two of you, and let all the dispatchers make a codebook for me in two months, during the rest time, and we'll take turns using ......."

Speaking of this, Wang Shihua seemed to remember something pleasant, his smile was a little sinister, but his tone was extremely relaxed: "It also uses internal and external use." ”

"Yes!"

The two nodded yes, but one of them thought about it and said with a smile: "The head of the family, the matter of compiling the codebook is actually not done by us at all, we should find outsiders, especially those who don't understand, to write it, in this way, it will increase the difficulty of being analyzed by others, and the confidentiality will be higher." ”

"Oh~?" Wang Shihua was also interested, and hurriedly asked, "It's better to let outsiders write it?" How do you say that? ”

"Head of the family, do you think that a person who can't even write all the letters from home, but can more or less know Braille, has written a book that even he himself doesn't know what is in it, isn't it more difficult for others to understand it?"

Wang Shihua was stunned for a moment, then came to his senses, laughed happily, but had N people in his heart - since the time of Wang Ji'an, the Wang family has paid attention to education, and in this generation, there are many young people in the Wang family who are literate and hyphenated, but those who half-understand and half-understand are also grasping a handful. Give a bounty and get a few hundred copies, isn't that a matter of moving your mouth? Especially like Tie Niu, what is written is guaranteed to be comparable to a wordless heavenly book......
