"Forestry Bureau, the goal is out again, or in the direction of Labor Park. ”

"Be careful not to disturb the target, and report the target's location at any time. ”

"Yes. ”

Originally, Lin Jia, who had always thought that the culprit behind Yang Wenjing's murder was Yang Yuting, was also caught off guard by the fourth possibility proposed by Ling Zhan. After careful consideration, Lin Jia, who had to admit that Ling Zhan's analysis and judgment was correct, almost experienced another sleepless night to sort out and adjust his previous thoughts.

Lin Jia knew that the responsibility on her shoulders could not allow her to make a little mistake. Otherwise, the consequences will be unimaginable.

Since Yang Yuting was not the murderer of Yang Wenjing and Yang Yutang, why did the organization behind him want to abandon him in such a hurry?

The surveillance of Yang Yuting was carried out long before he returned to China, and it can be said that although Yang Yuting himself and the organization behind him were suspicious, they did not have conclusive evidence that Yang Yuting had been exposed. It is only recently that the intensification of surveillance of Yang Yuting, thereby increasing the level of suspicion that the organization behind him has been exposed, has only recently begun. To be precise, it should have been after the murder of Yang Wenjing that the National Security Bureau stepped up its efforts, and the serious crime team came forward to exert some pressure on Yang Yuting.

But Lin Jia was very sure that all this started after he sensed that the spy organization was planning to abandon Yang Yuting. In other words, the reason for the organization behind it to abandon Yang Yuting is not on the side of the National Security Bureau, but because something happened within the organization.

"What could be the reason?"

The price to pay for cultivating a spy is very clear in Lin Jia's heart. Especially like Yang Yuting, who has the coat of a high-level intellectual, is proficient in computer programming, and has reached the level of a hacker, he is a coveted figure of various spy organizations in the world. If it weren't for something unavoidable, it would never have been possible to abandon Yang Yuting.

So Lin Jia listed one by one in his heart the possibilities that caused Yang Yuting to abandon him behind the organization, which could be inferred based on the information at hand.

1. The organization discovered that Yang Yuting's identity had been exposed - through what means, or was there a mistake in the National Security Bureau's surveillance of Yang Yuting?

2. Yang Yuting's position has wavered - there is no indication that Yang Yuting intends to surrender, that is, other spy organizations are optimistic about Yang Yuting and throw an olive branch to him, but because of his indecency, the organization behind Yang Yuting noticed it, so they made the decision to abandon Yang Yuting.

3. Sheche Baoshuai - Throw Yang Yuting as a smoke bomb to protect a more important member of the spy organization behind him in the General's City.

For this, Lin Jia thought about it for a long time. If this assumption is true, the importance of the member who was deliberately protected by the spy organization behind Yang Yuting is somewhat surprising. After all, in terms of all conditions, Yang Yuting is already a rare candidate for spy. It is more important than Yang Yuting, and he can even sacrifice him to protect the other person, which can imagine the key to the high status of that person in the General City.

In this way, it is a prerequisite for the organization behind Yang Yuting to make such a decision - the people they want to protect at all costs are currently under some kind of threat. Therefore, they had no choice but to create all kinds of illusions, allowing Yang Yuting to pretend to be the culprit behind the killing of Yang Wenjing and Yang Yutang, so as to remove the police's attention from the important people they wanted to protect.

Analyzing this, the identity of the important person who was protected by the spy organization behind Yang Yuting at all costs also appeared clearly in front of Lin Jia's eyes, which was exactly what Ling Zhan judged in Yang Wenjing's case, under the premise of the existence of the fourth possibility, the unknown person A who really killed Yang Wenjing and Yang Yutang.

Of course, this is only the result of Lin Jia's analysis based on the premise of the third hypothesis.

4. A dog-eat-dog victim hidden between several different national spy organizations in General City.

Lin Jia didn't need to use his brain much on this point, because Ling Zhan's analysis of the fourth possible existence was already very thorough. For example, the camera that was inexplicably broken in front of the laboratory building of the University of Science and Technology, such as Zhou Wei's bank card, such as the same hacker-level encryption program in the two notebooks that appeared in the two cases, and so on, and so on, such clues and suspicions that deliberately diverted the police's attention to Yang Yuting.

However, this possibility can only be established on the premise that his third hypothesis is not true, or that the fourth possibility proposed by Ling Zhan does not exist. Thus, in the cases of Yang Yutang and Yang Wenjing, the suspicions mentioned above are deliberately created by another espionage organization to target Yang Yuting and the organization behind it, so as to eliminate its competitors through the hands of the police.

Faced with the four hypotheses he put forward, Lin Jia finally crossed out the first and second, and only kept the third and fourth. In her mind, it was still confirmed that Ling Zhan's analysis and inference were correct. However, it cannot be ruled out that it was the mutual demolition (dog eat dog) between various spy organizations that played a role in fueling the flames, thus accelerating the decision of the spy organization behind Yang Yuting to abandon him.

At this point in the analysis, two obvious conclusions emerge.

First, the identity of the key protected members of a certain espionage organization overlapped with the identity of the unknown person A in Yang Wenjing's case. So Lin Jia followed this line of thought, summarized Ling Zhan's analysis, coupled with his own judgment, and sorted out A's identity characteristics.

First, the location is very sensitive, even important. Able to grasp the work trends of the serious crime team.

2. Controlling Yang Yutang and using it through some way or method.

3. I know Yang Yuting very well, including Yang Yuting's spy identity.

Fourth, Yang Wenjing knows him (her).

5. Mu Qixiong, or the people behind Mu Qixiong and the organization he or she belongs to pose a threat to him or her to some extent. (This is because there is no evidence that Mr. Mu is a spy.) So far, Mu Qixiong's role has been more like a small person who is driven by interests and runs for others. ）

Second, A and Yang Yuting belong to the same espionage organization.

At this point, Lin Jia will inevitably have a very frustrated thought in his heart - just as the serious crime team has done a lot of useless work in investigating Yang Yuting, it has also spent too much time and energy in monitoring Yang Yuting.

Because, in the same spy organization, A's existence value is obviously much higher than Yang Yuting. So when Yang Yuting felt that things were not good, especially when he felt that the police regarded him as a suspect in the two criminal cases of Yang Yutang and Yang Wenjing, and were anxious to get in touch with the organization behind it, the person who was originally responsible for contacting Yang Yuting was very likely to be A.

Just imagine, in this case, that is to say, when the organization behind Yang Yuting has already planned to abandon him, how can A still come forward to contact Yang Yuting?

So Lin Jia decisively issued an order to the monitoring points scattered throughout the city: "Attention to all monitoring points, except for the group responsible for tracking the target at close range, all the other groups have withdrawn and waited for the order." ”

But what Lin Jia didn't expect was that less than half an hour after she issued the order to withdraw most of the supervisors assigned to Yang Yuting, the group responsible for monitoring Yang Yuting at close range came back with a shocking news.

"Forest Bureau, we found a strong magnetic field with a very regular amplitude. ”

"Can you determine the center of the magnetic field and find the source of the emittion?"

"The center of the magnetic field is less than three hundred meters away from Yang Yuting in the morning exercise, in a pavilion. In the distance, you can see two men and one woman, three old men in their sixties and seventies, who are practicing the sheng flute ensemble through the musical instrument tutorial played on the radio. ”

"Didn't that strong magnetic field affect the radio?"

This is a very common sense thing, and the radio also receives electromagnetic waves, and when it encounters stronger electromagnetic waves, it is natural for interference sounds to appear in the radio. The stronger the magnetic field encountered, the louder the interfering sound will be, and sometimes it will sound very unpleasant.

"Nope. Forestry Bureau, we suspect that the radio is the source of the strong magnetic field. ”

"Possibly. However, it is necessary to be 100% sure before taking action. Lin Jia paused for a moment and said, "I will immediately send someone to follow Yang Yuting in your place, and you will follow after determining the source of the magnetic field emission." If it's really that radio, see where it ends up. At the same time, secretly investigate the identities of the three old men. If possible, try to find a way to bring that radio back without alerting the owner. ”

Lin Jia didn't say anything superfluous, because the special device that he had just received and could be worn on his wrist could automatically record the wavelength, waveform, frequency and other parameters of the retrieved electromagnetic waves. If you want to decipher the information transmitted in it, you just have to wait for the person who is tracking the magnetic field signal to come back.
