He closed the pen cap and looked at what was on the paper.
He turned to say: "From these two points, it can be seen that this person is not a hidden telegraph agent in Ice City, but has a hidden identity."
"Of course, if you don't hide your identity, it will be easily exposed." Wan Qun agreed with this point.
Without hiding your identity, your time will be freer, and you can have more choices about where to send your report. Even leaving the city and going to the suburbs or a more remote place to send your report is a good choice.
But this person does not, which means that his hidden identity limits this.
"But I don't recommend that you put all your goals on this person's identity." Wan Qun said to He Siliang.
Although he does not understand these professional issues, he can also understand other issues contained in them.
Wan Qun continued: "From what you said, it seems that this person only sends telegrams and does not receive telegrams."
"Indeed." He Siliang nodded and said.
Without a fixed time, it proves that there is no possibility of receiving telegrams.
Generally, there are two possibilities.
The first is to receive telegrams at a specified time.
The second is to wait a certain number of hours after you send the telegram before receiving the telegram. The above will arrange your work based on the content of your telegram.
The first and second types are used in combination, because some telegrams require a reply as soon as possible, and this time is not fixed.
Six hours later, twelve hours later, these are all possible.
The Secret Service also used these to arrest anti-Manchurian and anti-Japanese elements. They first found the place where they sent the telegram, but did not arrest them. They waited until a few hours later when they received the telegram, then arrested them, and at the same time intercepted the enemy's work arrangements.
But the master that He Siliang now thinks does not receive messages, but simply sends them.
The sending time is stipulated, but by not receiving the message, the risk is reduced.
"Juntong has other radio activities, so you can't focus on this one radio station." Wan Qun reminded.
There must be other radio stations that will accept the news from the military commander.
"I understand." He Siliang knew what Wan Qun meant, and was worried that he would be angry and insist on competing with this person, ignoring other clues.
"Did you bring the map?" Wan Qun asked.
Yu Jingque said with a wink, "I'll get it."
Come out of the office, go to the communications class, and get He Siliang's map.
After returning to the office, they spread the map on the table and the three of them stood up.
He Siliang lowered his head and said: "They have appeared in Butou District, Daoli, Taijiagang, Fujiadian, and Xinshi Street."
"Is the scope so wide?" Wan Qun frowned.
"A few places appeared very early, once before the new year, once after the new year, a little more than a month and a half, but they were also very scattered." He Siliang explained.
Judging from He Siliang's words, Yu Jingque believes that Ji Youning should have started working a few years ago, but not frequently, and may still be getting used to it.
However, in the past month and a half, it has been concentrated a bit, and it seems that the military commander has obtained a lot of information here.
"Draw the range." Wan Qun said.
The range was quickly drawn, and He Siliang said: "I have drawn it many times, and it is so messy that we can't even determine which area this person lives in."
This problem gave Wan Qun and He Siliang a headache, but it made Yu Jingque feel relieved. It seemed that the military commanders were very careful.
"What do you think?" Wan Qun suddenly asked Yu Jingque.
Yu Jingque never thought that Wan Qun would ask him this kind of thing, but he still had to answer.
"I think that the location is messy, which shows that the enemy is deliberately confusing us. I also think that the speculation just now may be wrong."
Yu Jingque said this while looking at Wan Qun, because it was speculated by Wan Qun, and he was worried that this sentence would make Wan Qun unhappy.
"Tell me about it." Wan Qun didn't show that he was unhappy.
"Just now we thought that the enemy could not leave the city because his range of activities was limited, but from these circumstances, it seems that the range of interaction is quite large." Yu Jingque expressed his doubts.
"If we go by this range of activities, the enemy can send messages out of our line of sight and even out of the signal capture range." Yu Jingque added.
In fact, Yu Jingque didn't want to say it, because by saying so, it seemed like he was helping the Secret Service arrest Ji Youning.
But Wan Qun would not ask Yu Jingque's opinion for no reason. Wan Qun must have discovered this. He asked Yu Jingque to say it, but Yu Jingque couldn't tell him, which seemed strange.
Although Yu Jingque could have pretended not to say anything, the excuse was that he did not dare to overturn Wan Qun's speculation.
But Yu Jingque's current situation is that he has just gained the trust of Wan Qun and is on the verge of being reused.
Wan Qun needs Yu Jingque to overturn his speculation, and don't worry about it so much, so that Wan Qun will find Yu Jingque useful.
If Yu Jingque was worried about offending Wan Qun and dared not speak out about this issue, it would leave a bad impression.
So when Wan Qun had already seen it, and Wan Qun knew whether Yu Jingque said it or not, and it would benefit him if Yu Jingque said it, of course he had to choose to say it.
Sure enough, after listening to Yu Jingque's words, Wan Qun nodded slightly and said, "Yes, judging from these points, there may be other special reasons why the enemy does not leave the city."
Of course there was a special reason. Ji Youning was worried about being discovered by Yu Jingque and it would be too late for her to go home.
Moreover, as a teacher in a school, she cannot ask for leave casually. Asking for leave will leave flaws.
But if there is a car, Ji Youning can still send reports in various places in the city. As for where the car came from, Yu Jingque feels that it has something to do with Yu Mosheng.
It may not be Yu Mosheng's car, but Yu Mosheng will definitely be involved, because this work is impossible for one person to complete, and the radio stations need to be constantly transferred.
"Special reason?" He Siliang asked.
"For example, due to work reasons, I can't leave for too long, or it's inconvenient for the people around me, all kinds of things." Wan Qun's words made Yu Jingque smile. After getting more information, Wan Qun's inference turned out to be more accurate.
.
"But we still can't determine his location?" He Siliang was a little annoyed.
However, Wan Qun felt that he had gained something. He said: "The enemy must have a regular job with fixed hours, such as a doctor, nurse, bank clerk, foreign bank clerk, teacher, clerk, etc. Secondly, he is very familiar with Bingcheng."
The one who sent the report was Ji Youning, and the one who was familiar with Bingcheng was probably Yu Mosheng.
Yu Jingque now believes more and more that this person is Ji Youning. Qin Jin also said that they had a telegraph master who went to the bank, and then Yu Jingque rescued Ji Youning at the bank. Looking at it this way, it is undoubtedly Ji Youning.
"There are so many people like this in Bingcheng, what's the scope?" He Siliang interrupted Wan Qun.
"Everyone has subconscious behavior." Wan Qun's words pulled Yu Jingque's gaze down to the map.
Wan Qun saw Yu Jingque looking at the map and asked for the second time: "What can you see?"
