Yang Jiji preemptively lit the fire for Fan Keqin, and then sat down again. Fan Keqin was still very satisfied when he saw this, but when he spit out a puff of smoke, he still said to Zhao Hongliang: "Before you get off work, go and keep an eye on Wei Ming and Chen Cheng of the Operations Section who were arrested by the section chief and Lao Yang before. Ask them to write a detailed action sheet and tell them when they will finish writing and when they will be released. Lao Zhao, after that, you will be responsible for checking the action sheet they wrote to investigate whether it is true. ”

Zhao Hongliang said: "Yes! ”

Fan Keqin said: "Well, you go and execute." ”

Zhao Hongliang immediately stood up and saluted, turned around and walked out of the office.

Fan Keqin looked at Yang Jiji and said, "Old Yang, Chu Tianfeng of the Operations Section was arrested by the section chief, do you know why?" ”

Yang Jiji nodded and said, "When the section chief asked me to arrest Wei Ming, he told me a word and said yes...... It is possible that this person is a spy of the Japanese. ”

"Hmm." Fan Keqin said: "So I want you to investigate who he has been in contact with these days, where he has been, what things he has done, and what calls he has made or received, remember, the focus is on around the 5th of this month." Do you understand? As he spoke, he had already taken out Sun Guoxin's warrant and continued: "You don't have to worry about anything else, this time it's a direct order from the seat." ”

Yang Jiji immediately said, "Understood, team leader, I'll do it right away." As he spoke, he got up.

Fan Keqin beckoned, stopped him, and said, "Wait, in addition, call a few brothers, go to his house and the telephone office to guard, see if there is a phone coming in, if so, immediately track down the address." ”

Yang Jiji said: "Understand, team leader, I will call a few reliable brothers to guard." ”

"Okay." Fan Keqin raised his chin at him and said, "Go ahead." Notify me immediately if there is news. ”

After Yang Ji went out, Fan Keqin slowly finished smoking a cigarette while thinking. At this time, someone knocked on the door of "Tuk Tuk", and then heard Han Qiang's voice ringing, and said, "Brother Fan, are you inside?" ”

Fan Keqin got up and opened the door, and said with a smile: "Why did Section Chief Han come in person, I won't be over with a phone call." ”

Han Qiang was not polite, smiled and sat directly on a chair next to him, and said, "Are you still polite to me?" I have a pretty good relationship with your brother, and when I was in military school, I listened to him always talk about you. As he spoke, he handed over a stack of documents in his hand. "I just came back from the seat. Come, let's take a look at it. ”

"Okay." Fan Keqin took the document with a smile, didn't read it first, but handed Han Qiang a cigarette, and said, "Section Chief Han, come, smoke a cigarette first." ”

Han Qiang took it, and then when he was smoking, Fan Keqin took a closer look at the records of the telecommunications department, and it can be seen from this document that Han Qiang's professional skills are still excellent, and the records in it are very detailed and organized.

Fan Keqin focused on around the 5th of this month, and sure enough, there was an unregistered signal record in it, and he deliberately pulled out this document and said, "Section Chief Han, what's going on with this record?" ”

Han Qiang jumped his eyebrows and said mysteriously: "I have seen this record before. ”

"Oh?" Fan Keqin said: "What's the matter? Tell me about it. ”

Han Qiang sneered and said, "This signal was captured once on the third day after the capital was moved, and it appeared for a very short time. There's no way to look it down. I suspect that the Japanese knew about our government coming from Nanjing on the third day after the capital was moved, and even before that, the Japanese already knew. ”

Fan Keqin frowned and said, "You said, the signal at that time was sent by the same spy team as this?" ”

"It's not all." Han Qiang said: "I am even sure that the person who sent the report at that time is the same person as the person who sent the report on the fifth of this month, and this person is likely to be a woman." ”

Although Fan Keqin had also been in contact with telecommunications in Germany, he was limited to sending and receiving, so he was not proficient in it, so he asked, "Oh? How does Section Chief Han judge? ”

Han Qiang said with a smile: "Everyone's dispatcher's techniques, severity, speed and slowness, and urgency are all different, from this point I feel that this dispatcher may be a woman, and the skills are quite good." ”

Fan Keqin praised: "When my eldest brother mentioned you to me at the time, he said that Section Chief Han's telecommunications technology is second to none not only in our intelligence department, but also in the whole country. ”

"Oops." Han Qiang smiled: "My brother is serious, I just eat the bowl of rice, it's not unusual." ”

"Nope." Fan Keqin: "Section Chief Han is too modest, what you just said is extremely helpful to our future investigation work." After a pause, he continued: "Section Chief Han, then what do you think about this mysterious signal that appeared at 7:30 on the night of the 5th, tell my brother again." ”

Han Qiang leaned back his chubby body to make himself more comfortable, and said, "As I said just now, this report was sent by the same person as the signal that was sent three days after the capital was moved, but I don't have a codebook now, so I can't decipher it." However, in terms of time, it took less than two minutes to send the report, and judging by the method and speed of the dispatcher, I feel that this is not a short content, about 50 to 70 words of content, and I can't go into more detail about it. ”

Fan Keqin let out a "hmm" and said, "I can't judge the approximate scope of the report?" ”

Han Qiang shook his head and said, "I have a few military radios, which are not professional monitoring and monitoring equipment, and the time is too short, so I didn't narrow the scope." ”

Fan Keqin was still a little reluctant, took out a map from the drawer, put it on the table with a pencil, and said, "It's okay, it's probably fine." Section Chief Han, look at what the scope is. ”

Han Qiang was not hypocritical, picked up the pen, measured it with his left hand on the entire city map, looked at the lower position again, and then drew a circle, smacked his lips with a pen, and said: "The range is too wide to check." ”

Fan Keqin looked at it fixedly, and saw that Han Qiang's circle almost turned the left side to the bottom, that is, to the southwest, which was similar to enclosing three-fifths of the city.

Indeed, I told the other party that the scope is a bit too big. But Fan Keqin still smiled and said, "Yes, the range is indeed a bit large, but the junior brother still has to thank Section Chief Han for his help." If there are any technical problems in the future, it is still necessary to trouble Section Chief Han. ”

Note: "I have received the signing information, please rest assured to collect it!" Hey! ”
