So Zhang Zhikai immediately handed over the mouth to Huazhang. After the latter got it, although it was only four o'clock, he still called Fan Keqin's home and told Fan Keqin about the matter.

After putting down the phone, Fan Keqin looked at his watch and found that it was still early. This was somewhat unexpected. Because of the detailed interrogation, he thought that at least he would get the normal time to go to work. I didn't expect Zhang Zhikai and them to do it so early.

But this is a good thing, and it also shows that Zhu Qing's bones are relatively soft, maybe he has just started the interrogation, and he didn't hold up at all, so he began to explain the problem.

Fan Keqin said goodbye to Lu Xiaoya gently and let her continue to fall asleep. I got up and washed up, and went straight out to the security bureau.

Hua Zhang had basically read a confession at this time, and was waiting for Fan Keqin. The latter led him straight into his office.

Hua Zhang handed the confession to Fan Keqin and said, "Brother, take a look first." ”

"Hmm." Fan Keqin stretched out his hand to take it and began to look at it. It didn't take him long to watch. Some things, such as recurring, are used to test whether or not to lie, and he doesn't have to watch them repeatedly, and he will talk about them later.

Now that we have not yet decided whether to startle the snake, we still need to be more accurate in terms of efficiency. Later, just look at it in detail.

It took about half an hour, and Fan Keqin basically read some key things. Hua Zhang saw that he had finished reading it, and took the initiative to say: "Brother, after I finished reading it, I first asked Zhang Zhikai to take his brother and go to No. 176 to squat again, mainly because I was afraid that if there was no one there, if Zhu Qing, an accomplice, found out that something was wrong, it would be bad." In addition, it is also a good time to see if the neighbors around him are aware of him after he is arrested. If there is, we will be able to control it in time. ”

"Well done." Fan Keqin said: "Have you found the codebook?" ”

"Found it." Hua Zhang said: "Less than five minutes before you came, Zhang Zhikai called and said that in the box of Zhu Qing's house, he found the book "Classical Interpretation". Zhang Zhikai tried to compare it with the "Classical Interpretation" according to the call password he received from Wang's pseudo headquarters before, and he was able to get it right, indicating that Zhu Qing did not lie about this matter. ”

Then Hua Zhang looked at Fan Keqin's eyes, and said, "Brother, next, I plan to deal with Hei Yu, do you feel okay?" ”

Fan Keqin nodded and said, "Yes, but you have to pay attention to the method." Now what we know about Hei Yu is only a few words of description, knowing that Hei Yu is Zhu Qing's upline, and he has been using the method of dead mailbox to contact. Nothing else is known. I just don't know, does this black feather have someone else like Zhu Qing, or is it a one-line one-person contact?

If it's the former, it's better for us not to touch the black feather for the time being. If it moves, there is a greater risk that the Japanese pseudo-spies will find out that they have been targeted by us. Even if we defeat all the spies who are connected with Black Feather, I am afraid that the Japanese pseudo-spies in other aspects will not be showing their heads, or they will be more secretive.

But if it's the latter, a single person and a single line, we can move this black feather directly. Like Zhu Qing, after holding it down, he immediately made a surprise interrogation and opened the other party's mouth. Then use Hei Yu's identity to continue to maintain contact with Wang's puppet headquarters, so that it will not arouse any suspicion. It won't bother the other party.

So when you deal with Black Feather now, the first task is to figure out what this person does and see which of these two situations it is. Then move again. ”

"Yes." Hua Zhang agreed, thought about it, and said, "Brother, do you think this is okay." I asked a brother who was about the same size as Zhu Qing to pretend to be Zhu Qing and go to the Red Wall Alley of Jialing Erdao Street to deliver a piece of information. But because we can't touch this black feather for the time being, the content of this information still has to be able to confuse the other party so that the black feather will not be suspicious.

In this way, trick Hei Yu into coming to get information, we will arrange it in advance, as long as he comes, let the tracking master directly stare at the other party. As long as we know who he is, whether he is a single person and a single wire, or if he is connected in parallel like an electrical circuit, then we will be able to figure it out. ”

After listening to this, Fan Keqin thought about it for a while and said, "Yes, but the content of the delivery should be carefully made." It can't be empty and strange, otherwise Black Feather may reflect it at a glance. Perhaps, he will quietly make us feel that he is not aware, and we will fall into passivity.

You can combine the content of Zhu Qing's confession and the death mailbox of the previous contact with Hei Yu to study it carefully. Use his tone, handwriting, and previous content information to see if he can extend a new message. Then use this information as a dead mailbox and trick Black Feather into appearing. ”

Hua Zhang said: "I understand, after getting the confession, I asked the brother of the Special Investigation Department to study the content of his confession, which includes the information he contacted Hei Yu before. I'll go back to them, believing that I can forge a letter of information that can fool Black Feather. ”

"Hmm." Fan Keqin said: "This is the first step you have to do. Other than that...... In Zhu Qing's confession, it was mentioned that he was asked to go to the current No. 176 with a big red sheet, did you find this thing? ”

"Found it." Hua Zhang said: "After arresting Zhu Qing last night, Zhang Zhikai left a few brothers to carefully search the room of No. 176. After Zhang Zhikai returned to No. 176 this morning, he compared with the searching brother and immediately found the red sheet. It's just that now the sheets are used for? It is not yet known. Zhu Qing guessed by himself that it might be used for signaling. ”

Speaking of this, Hua Zhang thought for a while and said, "Is it true, if he shows the sheet, it means that he is safe and can act." Then the rest of the people saw it and started doing something. ”

"I don't rule it out." Fan Keqin said: "But ...... I noticed Zhu Qing's speculation, and I also mentioned the word positioning. ”

Hua Zhang frowned and said: "Actually, I also noticed, it's just positioning, what position?" Positioning of aircraft air strikes? Use the big red sheets to locate the bombing target. But he couldn't hang a sheet on the defense building. Don't...... Agreed in advance, a building in a certain direction of the red sheets is the target of the air raid? ”

Fan Keqin nodded, gestured in front of the water cup with his hand, and said, "It's possible, you see, my hand is the sheet." Now let's agree that the building on the west side of my hand is the target of bombing. ”
