Duan Xiangbei said: "This time, when I was actually listening to Zhicang's report, I had the idea of asking your intelligence department for help in my heart. Those three telegraph experts, according to Zhicang, are all of a very high level, and they can greatly increase our chances of deciphering Japanese military messages, so there is no room for failure to accept them. Don't shirk me. ”

Qian Jinxun listened, nodded and said, "If I want to shirk it, can I come over with Keqin." Then he took out a cigarette and sent it around, puffed out a puff of smoke, and said, "Tell me first, what is the situation of those three people?" ”

Duan Xiangbei said: "Two of them are Zhikura's students, named Miyatake Yuto and Ogata Yoshiaki, according to the information provided by Zhicang, both of them were very talented in telecommunication decipherment when they were students, and one of them, Miyatake Yuto, once got the best graduation results in the history of their school. There is also a colleague of Zhicang, named Huagang Changying, who previously studied at the University of Pennsylvania in the United States, specializing in cryptography. The three of them used to have a good relationship with Zhikura, and they often discussed knowledge together, or always went to some izakaya for gatherings. Zhicang could feel from their conversation that the three of them were also quite annoying. Among them, Huagang Changying's younger brother died on the edge of the Great Wall because of the invasion of our country. It was because Hanaoka Nagaei had always been dissatisfied with them, and Yuto Miyatake and Yoshiaki Ogata were often bullied by the rest of their classmates in the country, and they also expressed their dissatisfaction when they gathered. ”

Duan Xiangbei spoke, took out a cigarette and handed one out one by one, lit it and continued: "Zhicang wrote a letter to them, and the words of the three people in the reply letter, although they did not say it explicitly, still carried this dissatisfaction, and when Zhicang replied to the letter, he invited them to come over. The two students agreed unequivocally. That Huagang Changying also meant this, but he hinted that he would be forcibly conscripted into the army soon and come to our country, and he would take the initiative to contact Zhicang again when the time came. Some time ago, Zhicang received a letter that Huagang Changying had arrived by ship, and belonged to the embassy in Shanghai, and was a member of the communication group of the chrysanthemum agency under its jurisdiction. In this letter, there is a one, or a few numbers, hidden in each paragraph, and the branch warehouse deciphers it in reverse order, so that it becomes the eight words that are heavily guarded and unable to move. ”

Qian Jinxun raised his eyebrows and said, "This is not a fishing trick of Little Japan, right?" Let us go over and rescue him, but set a trap in advance to defeat our agents in Shanghai. ”

Duan Xiangbei took a puff of cigarette and said: "No, let's talk about Zhikura Yaya first, he grew up in China when he was a child, although he went back to Japan during his studies, but after he came back, he has always performed well when he joined our military command." Speaking of this, he whispered: "His deciphering efficiency is among the top in the entire translation team." Speaking of which, Keqin also made great efforts, the original code book he seized, played a great role in the decipherment work, and the branch warehouse was originally Japanese, Japanese culture, or mentality is more understanding, after getting these original code books, it has become the most efficient cryptographic expert, those deciphered messages, after later comparison, the accuracy rate is also extremely high, this thing can never be faked. ”

Qian Jinxun nodded and said, "Well, if there is nothing wrong with that Zhicanya, on the other hand, you can't rule out the suspicion of Huagang Changying and the former students of the two Zhicang, right?" ”

Duan Xiangbei took a breath and said, "It can't be completely ruled out, those two students agreed too happily." I'm a little more suspicious of these two former students than I am about Hanoka Changying. After all, since Zhikura left Japan, these two students have been staying in Japan, and they haven't passed a few letters with Zhikura Yaya, and the environment can change people, and after so many years, who knows what they have become. And I have a little suspicion that these two people are spying on Huagang Changying. ”

"Oh?" Qian Jinxun flicked off the cigarette ash and said, "What do you say? ”

Duan Xiangbei explained: "These two people came to China with Huagang Changying. And he also worked in the Shanghai Chrysanthemum Agency. ”

Qian Jinxun listened, glanced at Fan Keqin, and said, "It's a bit too coincidental." ”

At this time, Fan Keqin, who had not spoken much, said beside him: "This kind of coincidence is not certain for the time being. ”

Hearing this, Qian Jinxun turned his head to look at Fan Keqin and said, "Don't you believe in coincidences the most?" ”

Fan Keqin nodded and said, "That's right, because there are no coincidences in this world at all." In fact, when we carefully analyze every seemingly coincidental event, there is an inevitability. However, there are many possibilities for those two people, one of which is that they are both experts in translating and telegraphing, and most of the agents from Japan will land in Shanghai first. And several of them are in the same university as each other, so the possibility of being transferred together does exist. However, as I said to Director Duan, this matter is indeed too coincidental, and we have to find some way to determine it. ”

Duan Xiangbei said: "Keqin has any good ideas? ”

Fan Keqin thought for a while and said, "I want to ask first, are these three people usually free?" ”

Duan Xiangbei said: "The brothers at the Shanghai station responded that they had found three people from Huagang Changying in a Japanese izakaya near the Bund a few times, which shows that they are still free. ”

Fan Keqin said: "That's easy, let our people pick up, have one night to escape from Shanghai, and let our agents set up contact points along the way, as long as they enter Changsha, the Japanese will definitely not be able to catch up." ”

Duan Xiangbei frowned and said, "The key is, how to determine whether these three people are really here." ”

Fan Keqin said with a smile: "It's very simple, when answering them, tell them three addresses respectively, and at the same time our people are watching from afar, if the Japanese do not ambush in advance, it means that there is no problem with the person at the corresponding address, if he does not appear, or there is an ambush, it must be a fake refuge." ”

Duan Xiangbei patted his thigh happily when he heard this, and laughed: "This method is good, simple, and practical. I just said that professional things have to be done by professional people. ”

Fan Keqin also smiled: "Director Duan praised it falsely. Well...... There are a few precautions for this method, that is, how to send a message, I think Huagang Changying once used encrypted letters to Zhikura Yaya, so can we also follow suit, and write three letters that seem to be normal correspondence between friends......"
