Outside a compound, Gui Youguang hid in an alley with the agents of the action team, secretly watching the movements in the compound. When he saw a car driving out, his eyes lit up.
It was Liu Gui's car. This guy was Xu Enzeng's confidant. He went out as soon as he came back, maybe to the storage point of the files. He called a spy who was good at tracking, and the two communicated in low voices.
"You are responsible for tracking Liu Gui, you know what to do."
"I know, secretly follow and monitor, looking for a foothold."
"Go ahead."
Gui Youguang patted his subordinates on the shoulders, and then focused on the cars of other personnel going out, especially those agents who drove alone, most likely to access files.
He never expected that Xu Enzeng would use the radio to contact the people at the file storage point. After all, the stability of the radio was not high, and the tubes were easily damaged. Once they broke, they would cost a lot of money to buy.
Moreover, most people subconsciously think that radio is a tool for long-distance communication. Xu Enzeng can be regarded as taking advantage of blind spots in his thinking. As expected, he came back from studying abroad and has some skills when it comes to seriousness.
However, just because Gui Youguang can't think of it, doesn't mean that others can't think of it.
When Zuo Zhong judged that there was a traitor and realized that Xu Enzeng was so cautious, he immediately thought of the radio station. What could be safer than not having to meet in person and only using radio waves to communicate.
Just like when he contacted the underground party.
So when Dang Gui Youguang was doing useless work, Zuo Zhong walked into the telecommunications department, surrounded by the smiling telecommunications section chief. Now facing Zuo Zhong, this person no longer had the unruliness he had when he was selling radio stations.
"Oh, we are really a distinguished guest today. How come Section Chief Zuo has time to come here? You are all dead. Come and make someone a cup of the good tea I brought back from Hangzhou to Section Chief Zuo. Hurry and go."
Zuo Zhong didn't care when he looked at this person's villainous face, and said cheerfully: "I'm investigating a case right now, let's see if you have any new discoveries here, and what's going on at Sanpailou in the past two days."
The chief of the telecommunications section was originally a machine operator and was not very knowledgeable about electrical detection. Upon hearing Zuo Zhong's inquiry, he quickly called the technical personnel responsible for electrical detection to report the specific situation to Zuo Zhong.
When the technician saw the legendary smiling tiger for the first time, his face turned pale with fright, and he stammered: "Report to Section Chief Zuo that there are no unknown radio signals near the Sanpailou. We have tried our best."
"It's really dog meat that can't be put on the table. It's useless."
The telecommunications section chief was furious: "Have you done a good job in detecting it? Section Chief Zuo is the detection expert in our department. He said that if there is a radio station on the third archway, there must be a radio station. Please detect it carefully for me."
This is a bit unreasonable. Without unknown radio activities, no matter how carefully they detect, there is no way they can find it. The technicians lower their heads in grievance and accept the baptism of saliva.
"Don't blame him, this case is a bit special." Zuo Zhong smiled and persuaded the telecommunications section chief, and then asked the technician: "Have you recorded all the activity records of Jinling City Radio Station?"
"Yes."
The technician puffed up his chest: "Whether it is a registered government radio station or a commercial radio station set up privately, we have recorded it, but we only have the start-up time and approximate location.
This also depends on the new electronic detection equipment borrowed by Section Chief Zuo, otherwise we can only determine the time and general direction of the startup. Everyone says that you and our Section Chief are the most knowledgeable officers. "
If you don't say that an honest man is flattering, he is amazing. His words made people feel comfortable. Both Zuo Zhong and the telecommunications section chief smiled, and the telecommunications section chief almost laughed out loud.
"The telecommunications department has done a good job." Zuo Zhong praised him against his will, and then said unceremoniously: "The intelligence department has discovered some new clues. Show me the electrical investigation records within three months."
"It all depends on Virgo's leadership." The telecommunications section chief gave Lao Dai a slap in the face, and then waved to the technicians: "You immediately bring a few people to send the electrical investigation records to Section Chief Zuo's office."
Zuo Zhong didn't stop him. This arrangement couldn't be better. It was really inconvenient for him to be here. He made perfunctory greetings with the telecommunications section chief. When he saw a few spies coming back with records, he left immediately.
He smiled and said: "Thank you. Corey still has some work to deal with. I won't bother you much today. Come and sit at my place when you have time. Although there is no good tea from Hangzhou, there is a can of good coffee beans."
"No problem. If you have anything to do in the future, just call and say hello. You don't have to go to such trouble. Don't worry, I will notify you immediately if a strange radio station appears near Sanpailou."
The telecommunications section chief bent slightly, standing slightly behind Zuo Zhong on his right, and enthusiastically escorted Zuo Zhong out of the door, treating him completely as his superior, completely ignoring that both of them were department-level cadres.
Zuo Zhong turned sideways and said with a smile: "Don't be like this. Although Virgo asked me to temporarily take charge of the office's work, in the final analysis, our positions are the same. You are too polite."
"It's different, it's different."
The head of the telecommunications section smiled flatteringly: "You are now a major, which is unique in the department. Naturally, you are a commander. We all say that you will be the second person in our department to be promoted to general in the future."
Bah, you are the general.
Zuo Zhong felt that the current spies spoke in a yin and yang manner. Wasn't this a curse on me to enroll in Gongdelin early? But it was hard to say anything in front of a smiling face, so he immediately laughed and left.
After leading people back to the Intelligence Section, Zuo Zhong asked the agents from the Telecommunications Section to put down their things. He also said hello to He Yijun and asked her not to let anyone in to disturb him, then he dove into the office.
Not that it's for secrecy.
But the amount of data he has to process is very large. There are millions of people in and around Jinling City, and there are many commercial institutions such as banks, trading companies, newspapers and magazines. These places all have radio needs.
This resulted in a large number of radio signals in Jinling. If you don't hurry up and read them all, an intelligence section chief who cares so much about the radio station can easily arouse the suspicion of others, such as Lao Dai.
Zuo Zhong first checked the recent records, focusing on the records of telegrams sent by Liu Gui after he returned to the special agent headquarters. He was afraid that the telecommunications department had not yet made a record of today's detection.
Fortunately, the technician from the telecommunications department was very prudent in his work. He quickly discovered a message sent today. There were 25 messages in just two hours, which shows how busy the business has been recently.
"It's clear, that's not it."
"This is not the frequency of camping trips."
"No, it's still the frequency of camp,"
Zuo Zhong quickly eliminated some records that were obviously not secret communications, but in the end there were still 7 messages left. At the same time, these 7 messages were sent throughout the two hours.
There are so many clues.
He originally wanted to find a transmission time, and then find a radio station that had records of sending and receiving telegrams at the same time. He could find something by comparing it. Now it seems that it is not that easy, but it is not impossible.
If the simple method doesn't work, then use the stupid method. This is why he asked for three months of electrical reconnaissance records. In addition to deceiving others, the more data, the more accurate the intelligence he can mine.
Zuo Zhong calmly wrote down the transmission times of these seven messages, and marked the radio stations that had records of sending and receiving telegrams during the same period. He was done with them all. The number of radio stations made his hair tingle.
There were 92 radio stations associated with these 7 reporting times alone. For the first time, he felt that the wireless equipment should be taken care of. If the spy radio station was also hidden in it, he would have to find it in the Year of the Monkey and the Moon of the Horse.
Zuo Zhong classified the 92 radio stations and excluded all known government radio stations. It was impossible for Xu Enzeng to place people in the secret service headquarters, and similarly he would not place people in other agencies.
If he wants to protect Wang Lizhong, he must first ensure that the least number of people know about it. If he is placed in a Guo Party agency, it won't take half a day for the news to spread all over Jinling.
Compared with those party and state officials, Song Minghao can be said to be tight-lipped.
At the same time, the government radio stations that can be marked by the Telecommunications Section are all large yamen, and the secret service headquarters does not have such a big face to ask the other party to cooperate with intelligence operations. These two points determine that these radio stations have no investigative value.
At this point, there are still 51 suspicious radio stations left in Zuo Zhong's hands. Judging from the detection records, they are distributed throughout the city. They seem to have no intelligence value unless there are other reference objects.
"Lao Zhang, Lao Xie, Sister Gu, it's up to you."
Zuo Zhong muttered something silently in his mind and began to compare the records of these 51 radio stations with the time of the Jishi Pharmacy explosion. As long as the radio stations appeared before the explosion, all radio stations were excluded.
Only after Lao Zhang and others were arrested or sacrificed, Xu Enzeng had time to arrange for the traitor Wang Lizhong to identify the Jinling underground party. He set the reference time after the bombing in order to be more accurate.
The comparison process was not easy. It took several months, and there were countless records. If you were not careful, you would have to start from the beginning. Zuo Zhong glanced at the window sill, turned on the lamp, lowered his head and concentrated on screening.
One, two, three. . . .
From evening to late night, and then from late night to early morning, the office was filled with the smell of cigarette smoke, the cigarette butts in the ashtray piled up into a hill, and only a thin sheet of the originally thick detection record was left.
Zuo Zhong took out the last cigarette and threw the cigarette case into the trash can. After lighting it, he stretched and looked at the table. After finishing this last cigarette, the traitor's tail should be exposed.
Thinking of this, his eyes were full of coldness. It was Wang Lizhong who had caused so much damage to the underground party. After finding this person, he wanted to see if the other party's heart was dark.
Otherwise, how could Wang Lizhong do such a thing, betray his comrades, and persecute those brothers who had fought alongside him? It would be a sin for such people to live one more day in the world.
Finally, before the agent started working, Zuo Zhong reduced the 51 radio stations to 3. He looked at the records of the three radio stations and smiled, Wang Lizhong, we are about to meet, just wait.
He silently read out three locations: "Central Chinese Martial Arts Hall, Jiming Temple, and Central Party Headquarters."
