Yang Zhen, who was a little impatient because he couldn't think of a way, heard the sound of Guo Bingxun's fingers knocking out what seemed to be a small song, and he couldn't help but raise his head and look at Guo Bingxun for a long time before saying, "Brother Guo, what kind of song is this knocking, is it quite good." ”

Hearing Yang Zhen suddenly ask himself about this, Guo Bingxun smiled without paying too much attention to it: "This is a popular traditional tune "Picking Flowers" in Sichuan, I often heard soldiers sing it when I was stationed in Sichuan, I always liked it, so I wrote it down." Every time I feel upset, I feel much better when I listen to it. ”

"I just saw that I was a little annoyed, but I didn't know what you were thinking, so I felt a little inconvenient to ask, so I couldn't help but knock up, hoping to help you stabilize your feelings." Guo Bingxun smiled.

Regarding Guo Bingxun's words, Yang Zhen shook his head and said: "I don't have any research on music, and I can't say that it's a little incomplete in five tones." I like it so much that I can't call it, I just feel good. But Brother Guo, I want to ask you, do you know anything about radio? Especially code? ”

Hearing Yang Zhen ask him if he understood radio and code, and his head didn't turn slowly, Guo Bingxun, who went there, immediately vaguely guessed what Yang Zhen meant. It's just that he was still a little uncertain and said, "What does Brother Yang mean?" ”

Yang Zhen didn't answer his question, but directly came to demonstrate the action. Yang Zhen lifted the handcuffs and gently knocked on the wall a few times. Yang Zhen's knocking sound was not loud, and the Japanese guards would not hear it even in the corridor. However, although Yang Zhen was sure that the sound made by the strength of his knock would not be heard by the Japanese guards in the corridor, he was not sure if the next door could hear it.

This building of the Japanese army is extremely sturdy, and there is no such thing as the tofu scum project that does something here in later generations, and everything next door can be heard clearly. Looking at the heavy wall, Yang Zhen still needs to try a little bit as to how much force to use not to attract the attention of the Japanese guards in the corridor and to let the next door hear.

Seeing Yang Zhen's actions, Guo Bingxun's eyes lit up. And then the response from next door surprised him even more, and he completely understood what Yang Zhen meant. Guo Bingxun said with some excitement: "When I first joined the Sichuan Army, I served as a communications staff officer in the communications department for more than a year. For this ciphercode, although it cannot be said to be an expert, it is not too much to think of itself. ”

Hearing Guo Bingxun actually admit that he was proficient in radio business, Yang Zhen couldn't help but look up at him in surprise. After two days of contact, Yang Zhen found that he was extremely proficient in staff business. Now that he heard that he actually knew how to telecommunications, Yang Zhen felt a little incredible. The guy in front of him, who doesn't look amazing, is actually an all-rounder. Such a talent will be extremely valued there, how could he be a prisoner?

Seeing Yang Zhen's somewhat suspicious gaze, Guo Bingxun smiled a little knowingly: "When I was studying at the Saint-Cyr Military Academy, my instructor once said to me that as a qualified combat staff officer, you must understand the importance of communication security in the war to the success or failure of the war. ”

"In modern warfare, there are many reasons that determine the outcome of both sides. But it is definitely not a simple factor of troops and equipment. One of the key reasons is whether the communication is smooth, whether the troops can be effectively organized, and whether the orders transmitted are safe or not. In modern warfare, radio has replaced the original carrier pigeons and manpower communications as the main means of communication for the military, especially at the campaign level. ”

"Even in the not-too-distant future, radio communications will replace some tactical means of communication, such as bugles and flags. Therefore, whether the communication is secure or not can determine the success or failure of a battle or even a campaign. ”

"Many military operations fail because of leaks in the process of communication, just like your communication code is deciphered by the adversary, then your overall deployment is not protected in the face of the adversary. This way, even if you try your best in battle, it will be difficult to win. ”

"With his encouragement, I have been able to learn a lot about telecommunications in my spare time. In the past few years, although it cannot be said to be a great success, at least it is not a problem to send and receive newspapers and decipher some simple passwords. Because I have learned this, I have been in the communications office when I entered the Sichuan Army, and later because of the Anti-Japanese War in Sichuan, I was transferred to the staff office as an operational staff officer and started my profession. ”

Speaking of this, Guo Bingxun glanced at Yang Zhen before he said: "As for what really made me interested in communications and made a lot of painstaking research, it was some rumors of your army that I heard after I arrived in the Sichuan army. ”

"In the course of your army's so-called Long March, both the Central Army and various local factions have repeatedly failed to intercept your army. Especially after the Battle of the Xiangjiang River, your army seemed to be able to predict the future, and always avoided the encirclement of the national army lightly. ”

"When I heard that, I knew there had to be something wrong with that. Although your party has always been known for its ability to infiltrate, there must be many of you in the armies of various factions. But the information was so timely and accurate that it was impossible to rely on those spies alone. ”

"It's okay for the Central Army, after all, you have worked together for many years, and you have already formed a situation where you have me and I have you. This kind of interpenetration cannot be completely solved by means of slaughter alone. No matter how hard we try, the supreme authorities, I am afraid that we will not be able to completely eliminate your party forces in the Central Army. Presumably, there should be a lot of you in this central army, right? ”

"But the local factions are different. Although I returned from studying abroad, because of my father, I defected to the local army. Although it is not a long time, I know that many local generals like to control the troops through their own kinship forces, and many generals are interconnected, and most of the key departments such as staff officers and adjutants at all levels in the army are also served by their sons and nephews. ”

"You can penetrate the grassroots, but you can't necessarily penetrate the top. It must be known that the mastery of the powerful army in many places is even higher than that of the central army. Because they know that with an army they have their own qiē, and without an army they are nothing. ”

"So I think that the most likely reason why your party and your army can get information so quickly is that you have deciphered our communication system. Although radio stations have been popularized in various units of the national army, the means of communication, especially the setting of passwords, are still very backward compared with those in Europe and the United States. Many of the codes are very simple and not difficult to decipher. ”

"Not to mention the miscellaneous cards in our places, even the password settings of the Central Army are not much better. You have the strong support of the Soviet Union behind you, and there must be many such talents trained in the Soviet Union. ”

"With the support of the Soviets, it shouldn't be difficult for you to decipher our code. In addition, I have been wondering if it is the Soviets who have provided you with some special listening equipment that makes you so skilled in this regard. Because many times when we deploy, your troops are on the march that the radio can't set up, but you can still accurately anticipate our detailed deployment. I have never been able to understand this. ”

Yang Zhen was very disgusted by Guo Bingxun's words that there was support from the Soviet Union behind him. But Yang Zhen knew that these were the ideas of most national troops. They all think that under the same *** ancestor, they are all ***, and the Soviet Union will definitely give a lot of support.

Although Yang Zhen was a little unhappy with Guo Bingxun's question, in order not to create a barrier to future cooperation, Yang Zhen still felt that he should make his words clearer. It's just how much to say so that it is not a leak, but it made Yang Zhen hesitate.

Yang Zhen didn't know whether he and these fellow refugees could finally get out of trouble, let alone be sure. Now he hasn't thought about it that much. What he thinks about most now is to look for an opportunity to fight to the death, even if he dies, he can't become a real product of the Japanese army's bacteriological warfare. As for whether it can succeed in the end, Yang Zhen still doesn't dare to think about it. After all, he doesn't even have a rough plan right now.

Although he didn't know if he could get out alive, Yang Zhen still didn't want to reveal too much that was already known to passers-by in later generations, but it was still a top secret in this era. But Yang Zhen also knew that he couldn't help but answer these things.

He knew that Guo Bingxun's question was not so much to find a secret, but rather to find an opportunity to answer the questions in his heart, and at the same time, it was also a litmus test to test whether he would be honest with him.

You must know that before he was captured, he was just a small company commander, and even if he mixed in the division headquarters, he was just an ordinary enemy engineering officer. These confidential things are known to themselves there. He couldn't have known anything from himself.

If these top-secret things were known to the little company commander himself, then the disproportionate **, which was still weak and disproportionate compared to the national army, would have been eliminated long ago. Why didn't you wipe out people after ten years of fighting? **'s secrecy is far from being decided by the first day, and the national army that will be known all over the city the next day can be compared.

Although he was a little disgusted by Guo Bingxun's somewhat clever temptation, Yang Zhen also knew that in today's extremely bad situation, this kind of caution was still necessary. Even if you still appreciated it a moment ago, you should still be cautious. Because after all, this is a matter of life and death for hundreds of people. If the chosen partners do not trust each other and are suspicious of each other, it will be a catastrophe for everyone.

And that's without taking into account the estrangement caused by the decade-long civil war between the two armies. Yang Zhen had personally heard his correspondent Xiaohuzi call Guo Bingxun a white dog, and when he was on the train, Yang Zhen had also heard those captured soldiers of the national army privately call themselves **. This mutual distrust cannot be remedied in a short period of time, nor is it necessarily something that can be changed by a bad environment. Yang Zhen knows that in Guo Bingxun's view, mutual honesty is the basis of cooperation between the two sides. So Yang Zhen knew that he had to answer this question.

Yang Zhen pondered for a moment before saying, "Brother Guo, you are wrong. We have some means of deciphering your code, but it would be unrealistic to say that there is support from the Soviets. It is not so much that our people were trained by the Soviets, but that they were all trained by your national army. ”

"There are a lot of people there who have been converted from prisoners of war from your national army. These people, especially those from the Central Army, are classmates and are familiar with many of your Central Army operators. ”

"Let's put it this way, they are even so familiar with each other that they know that the other person is their classmate, who is serving in your unit. This way, you can get a rough idea of which army is on the other side. There were a few operators in the army before me who came from your national army. This is also something I learned when I was working in the division headquarters. As for whether there are other means, I don't know at my level. ”

Speaking of this, Yang Zhen, who didn't want to talk about this issue, said: "Brother Guo, you are proficient in radio affairs, but he doesn't understand your subordinate next door to us." If he doesn't understand, even if we knock on the sky, we will be deaf and listen to thunder. ”

"He's a big thief, and he knows a lot about the skills of killing people and setting fires, but if he talks about radio and such things, he knows there. However, although he didn't understand, one of the two people in the same cell with him was a newspaper operator of the 122nd Division of the Haragawa Army, who was captured in the First World War in Tengxian County. It's just that the background of this operator is a bit complicated. If I'm not mistaken, he should be the one who was installed in the Sichuan army by the military commander. ”

When he said this, Guo Bingxun was slightly hesitant. It is clear that while he does not trust the people of the military command, he is also disgusted, and more wary.

After listening to the hesitation in Guo Bingxun's words, Yang Zhen smiled slightly, when is this still the military unified. I'll wait until I can get out. It's just that when Yang Zhen just wanted to comfort Guo Bingxun and ask him to temporarily give up this prejudice, his words were interrupted by the opening of the cell door. As the cell door opened, a man covered in bruises was pushed in by several Japanese guards. Looking at this newcomer, the two of them invariably stopped the conversation.
