After waiting for a while, Lin Mo actually pulled in the phone. After confirming that it was pulled into the target room, he immediately informed the situation.

On the wiring side, when they were about to transfer the apartment number, they had already started to check the number. After receiving the notice, they also compared the number one, which was the order that Zeng Wenchong had just transferred to them.

A man who looked like a manager immediately picked up the phone and pulled it out. In a guest room on the other side, Zeng Wenchong answered the phone. He brought some people from Sha Lihai's group to support him and personally took charge of contacting and docking with his informant.

"No. 27, Area C..." Several records were placed on the table where the phone was being played. After Zeng Wenchong compared and confirmed, he pressed and held the microphone and said to the team members in the house.

After confirming with Zeng Wenchong, the team member immediately ran out of the room to the roof, ran to one side, took out two clothes of different colors and started waving it, conveying the information to a communication node on the roof of a high-rise building in the distance.

Area C No. 27, No. 27 is a telephone number and the number of the corresponding location. Area C is the area where the surrounding area is divided, with several high-rise buildings as nodes, with the main purpose of solving the last section of information transmission.

The clothes are white, black and red, white is ten digits with two digits, black is zero to five in single digits, red is six to nine in single digits, zero is lifted up and put down again, and so on, six is ​​lifted up and put down again, mainly because they are afraid that too many times will lead to wrong numbers.

This can actually be considered as a simple agreement on the flag language by yourself, without using colorful flags, one is not prepared, and the other is to minimize the attention of people around you.

As for why there is no use of the whistle of the Operation Group 2, there are many people on the streets of Louwai, and the noise is too disturbing. If the sound is small, it will not be far away. If it is large, it will easily attract the attention of people around the place where the sound is emitted. At present, most of these information transmission methods can only be used on the spot.

Back to the topic, the high-rise building in Area C that the team members faced was confirmed through a telescope that the team members received the correct information. After sending out the feedback signal, they passed the information to several other areas.

The team members of the high-rise building in Area C ran to the other side of the roof of the building and passed the information to the three-person surveillance team on the roof of the building not far away. After confirming the situation, the other party divided the two and went downstairs, leaving one person staring at a place. The senior team members also passed the information to another surveillance team.

Du Mingsheng is in the B area because it is close to the area where the opponent called the previous two times, and he judged that the opponent might be in this area with a higher chance, but unfortunately the opponent went to the C area in the other direction.

After receiving the news, Du Mingsheng did not hurry to support him, but took out a simple picture of the surrounding streets, with two uneven red lines on it, and combined them into an X-shaped shape.

The upper and lower areas divided by the x-shaped shape are DB, and the left and right areas are the boundary lines of AC, AD, and AB. They are close to the location where the numbers were pulled out for the first two times. The AD point is close to the junction point, and the AB point is far away. The vertical line connected to the two points points points to Area B and the other side points to the far point of Area A and Area B. However, the far point is an ordinary residential area, so Du Mingsheng judged that the probability of Area B is greater.

The hotel where Zeng Wenchong is located is located near the junction point in Area D. The height view is not the best, but the room is set up with telephones in the room to facilitate communication with the outside world. Moreover, the connections in the hotel can provide convenience for their activities.

In the simple picture, Du Mingsheng connected several places, then drew the center vertical line as the intersection point, and also circled the several places, and finally set his sights on a place not far away.

Du Mingsheng directly led his men to the area where he locked in to set up defenses. As a result, he met Sha Lihai who came from Area A, and the two of them thought of going together.

Sha Lihai handed over some of the team members he brought to Du Mingsheng for the control work in the area commanded by him, and he took the remaining team members to the road leading here in Area C.

The two of them had a correct choice. Although the target was still talking after the team members arrived and targeted them, they hung up and left without a long time. If Du Mingsheng, Sha Lihai would come from afar and could only escape.

Sha Lihai brought two subordinates to the single room facing the street on the second floor of a restaurant, holding a telescope and staring at the distant intersection, bustling with pedestrians.

"The target wore a medium-gray baseball cap, a medium-gray coat on the upper body, dark gray trousers on the lower body, and a pair of gray-blue canvas shoes on the feet... I saw that I was over 20 years old and had a slightly short and strong head... You inform Officer Du of these characteristics..."

Not long after the target passed through the street intersection, it was locked by Sha Lihai. Except for the team members following behind, the target's anti-tracking and anti-surveillance actions should not be too obvious in Sha Lihai's eyes. It's not that the target is inferior, it's considered to be average! But this level is not enough in Sha Lihai's eyes today.

"Go down and bring the people who are following behind. They don't have to continue following here..."

Sha Lihai arranged the remaining team member, but it was not because the team member was exposed. From Sha Lihai's perspective, the opponent's anti-tracking and anti-surveillance actions were nothing more than habit or caution, and it might even be just a process-based standard behavior, and there was no sign of tracking behind him.

Sha Lihai defends the area behind him, which Du Mingsheng controls. Just like his perspective at this moment, the outsider's vision is often more likely to find something than insiders.

...

One team and another team, after collecting and monitoring various situations in the hospital, a large amount of information was gathered at the command point, but many people were instead straightened by this information, and the information was as messy as a mass of wool and could not be clarified.

However, Liu Zhenshan fell into deep thought when he looked at the picture in his hand. He listed all the personnel information in the feedback information, and then marked the relationship between them.

He made a total of twenty or thirty copies before he barely marked a relatively clear relationship diagram of the character, but the feedback was lacking some key information that was hidden very deeply. The diagram still gives people a sense of separation and some places cannot be connected.

This chapter is not over, please click on the next page to continue reading! For example, they found two dead mailboxes that conveyed information, both of which were around the cottage, and they also used three goals again. Two were subordinate officers, one was engaged in paperwork in the headquarters, one was a deputy officer of the city defense subordinate unit, and the other was the person who took the situation away, and the employee responsible for cleaning and cleaning the cottage and the surrounding area.

The employee was an elderly widowed man in his fifties and was quite strong. According to the information learned, one of his sons was arrested by Ding Dangbing, and later served as the squad leader of the transport corps in the city defense logistics department. During the subsequent transportation process, the ship overturned and rescued a logistics officer and died.

His hometown was also affected by disaster. The old man's other children and his wife passed away one after another. Later, he went to Nanjing to find his son and was rescued. The officer arranged for him to go to the hospital to do some miscellaneous work. However, the officer died of illness soon and the old man was excluded from the dirtiest work in the hospital. However, Liu Zhenshan is currently skeptical about his identity information.

After the old man took away the information, the person handed over to the pharmacist. The other party was indeed involved in the case, but according to the report of the surveillance personnel, the other party did not have any other suspicious interactions or interactions with the old man.

However, the old man could take it away in a short time after the other party placed the information. The other party's inference that the signal was sent through admission and other records was once suspected. However, through careful verification, the old man's workload was not low and he could not move in the work area for a long time. For example, the cottage needed to be cleaned up in time and at high frequency, there were still many miscellaneous tasks in the hospital. He had to help him with the inference. When there was a goal to convey information, the other party was not transporting garbage in the hospital.

If he is unable to access the admission records, it means that there is at least one unaware of the hospital, and the Xun number that has received and sent it to retrieve information.

After the pharmacist received the information, he handed it over to the officer guarding the drug warehouse, and the other party himself or borrowed from others to pass the information to the drug dealer.

The situations I have found at the moment seem to be centered around the pharmacist, but Liu Zhenshan always feels a little weird when he looks at the relationship chart.

Regarding this situation, a group leader was somewhat shaken about his previous judgment, questioning whether there were any errors in the early investigation of the pharmacist. At present, more in-depth investigations have been carried out around the other party.

"...Group Liu, I went to the hospital to observe the doctor and the doser for a while, and then asked for some details in detail, which really made me discover some new situations."

Zhang Jingmin, who looked listless, immediately became more energetic after entering the door. He gave himself a few sips of water to moisten his throat, and then talked about this discovery.

“… Through inquiring about several suspected employees, I learned that the pharmacist would usually take care of the old man and call the other party to clean the office and other places, so that the other party can do less hard work.

When I got these messages, I thought the other party had bought people's hearts and asked the old man to do these things for him. However, after observing the pharmacist, I found that he seemed to be a little afraid of the old man, and the real situation might be exactly the opposite of what was revealed in the open.

Of course, it may also be due to other emotional reasons, but as I saw it at that time, the pharmacist's eyes swept to the busy old man, and suddenly stopped and turned to another place, and a smile on his face disappeared.

After further inquiry, I also found that the pharmacist usually does not go to the hospital's cottage and would rather go back to the room and use a urinal to solve the problem. These situations are also indirect evidence."

After Zhang Jingmin finished speaking, Liu Zhenshan picked up a brush and drew it on the paper, and finally placed a brand new interpersonal relationship picture in front of Zhang Jingmin, but this time the central character surrounding the old man.

"...Liu Group... Are you talking about... this intelligence network in the city defense revolves around the old man? He may even be the most core and key leader of the entire intelligence network?" Zhang Jingmin spoke in disbelief.

"...The reaction is quite fast, otherwise what do you think will be?" Liu Zhenshan nodded and asked with a relaxed and freehand smile.

"I thought before that he was just a Japanese spy with a pure identity. The pharmacist might have been so afraid of him because he was instigated or coerced. After all, his disguised identity... is really..."

Liu Zhenshan nodded and said, "I vaguely suspected that his identity was not simple before. After all, an old Japanese gangster at such an old age is still lying on the front line of intelligence. That is definitely an old fox-level. No matter what the reason, he must be a key role in it.

But I only think it is an important and critical role. After all, he personally intervened in an important part of the intelligence network and was still this identity. Until you talk about the pharmacist's reaction to it, I felt that I might have thought it was wrong."

After saying that, Liu Zhenshan took the previous relationship picture and handed it over to continue and said, "I always felt something was wrong with this picture. Now, is it reasonable for this old man to change it to the center?

The old man is strung with various lines of intelligence collection and the channels for intelligence transmission. He is in the middle key link. All intelligence and information orders need to be handled by him, and he is also in the safest position in this intelligence network."

"The safest?" Zhang Jingmin looked at this relationship diagram carefully, and it was a little uncomprehensible. Isn't this location the most dangerous?

"...Do you think this location is the most dangerous? In fact, this is just the surface. When we investigate this intelligence network, we can start with it at the beginning, which is nothing more than two links: the stealing and leaking of secrets and the intelligence transmission process. The hospital's chances of being exposed to us at the beginning are the smallest or even slightest.

Although the secret leaks have a direct intersection with them, we have to follow this line to check it. How likely is it to lock an old employee who swept the cottage at the beginning?"

Speaking of this, Liu Zhenshan frowned and called a team member in charge of the order to arrange for the hospital to temporarily lift the surveillance of the old man, prohibiting the investigation and close surveillance of the cottage and nearby, and only medium- and long-distance surveillance work on this place is retained for the time being.

"Group Liu, what do you mean? If we investigate normally and cannot lock the old man in the first time, and then carry out control and other actions in that area, it will be easy to be observed and then fail?"

"Yes..." Liu Zhenshan nodded and said, "Once it is discovered, the other party will inevitably stop moving and enter a sleepy state. Then the investigation will basically only end here. As for whether the other party can discover it, I believe he has this ability.

Fortunately, because the time nodes of our investigation were special, we had many concerns, and we were more cautious in our actions. In addition, the hospital was a relatively closed environment, so we did not act rashly in it.

Because of the development of the situation, more personnel were arranged for the hospital, more "patients" were welcomed, which greatly covered our actions. In addition, we used various means to mobilize the other party, so we had so much available information in a short period of time without being discovered.

As for the information transmission line, it is even more difficult to find him. I will push him against him. First, the pharmacist, whether it is out of fear or other reasons, can have such a big reaction to him, and probably the other party has been holding him tightly.
