Time is approaching midnight and late at night.

The idea of ​​attracting the security squad of the relay station lost three people. Liu Fei and Liao Genzhu team had twelve people left together, and Qu Sen's thirteen teams left the 047 area where the Blue Command was located and directly penetrated into the direction of 259.

After crossing the plain river network and entering the hilly area, immediately use a straggler line to open the distance and search and advance.

Although our target area is 259 and going east to the edge of the exercise area, no one can tell which direction the three guys disguised as teachers and students of Forestry University escaped.

"Qu Sen, it took more than two hours from the time we left until we found that the three people were missing, and then we completed the peripheral blockade. This took only four hours together. Do you think they have already left the exercise area now?" Liu Fei washed his face in a stream, and during a short rest, Liu Fei couldn't help speaking.

"From 240 to the edge of the exercise, there are more than 30 kilometers of mountain roads in the nearest direction. You must avoid the blue anti-osmosis troops and checkpoints in the middle. Unless the three of them are faster than our off-road speed, it will be basically impossible." Qu Sen took a sip of water and swallowed it slowly and said.

"Just like those three people, and two women, I will definitely not be able to run out." A warrior said hatefully.

"Maybe they are professionally trained spies or mercenaries, it's hard to say." Liao Genzhu, who had calmed down, responded.

"Don't worry, the police, armed police, and even the reserve militia were launched, and they couldn't escape." Qu Sen comforted Liao Genzhu and stood up with his knees.

"What, I'm caught a few people who killed me." Liu Fei gritted his teeth and spitted out, and shouted to the warrior: "Stretch the distance and continue!" It was obvious that the two comrades were injured and made him angry.

The thirteen-man team, even if they are three meters apart, could only search and move forward. And at night, it was too small to say that the hilly land where there was no end to the top of the mountain could not be seen.

If you look at the entire exercise area, it will be even more insignificant.

In fact, after searching for a while, after everyone gradually calmed down, every soldier in the team realized that if he wanted to search the three people in such a large range, even if all the participating troops on both sides were thrown out to pull the net, it would be like a sieve.

The reason why everyone insists is that one is because their comrades are not sure about their lives and deaths. There is nowhere to vent their fire in their hearts, and they feel that they have to do something. The other is that there is a drone with a heat sensor in the sky that is constantly reconnaissance, and once the reconnaissance satellite enters the window period, it can also conduct a wider range of seamless reconnaissance.

Just as Qu Sen's team was searching in the mountains, the reconnaissance satellite finally entered the window period, and at the maximum effective distance of the thermal sensing lens, the battlefield monitoring of the limit range is being carried out. The focus of the reconnaissance of the drone has changed to the blind spot area caused by the satellite due to angle.

When the reconnaissance satellite completely swept the exercise area, Qu Sen's team finally returned to the valley where the three local personnel were found. Looking at the place where the tents were originally built, it had been cleaned up, and some soldiers couldn't help but curse.

"What are you scolding? The cleaner they clean up the scene, the better!" Qu Sen shouted, seeing everyone looking at him, and explained: "There are only three of them. The more they want to wipe the traces, the more time they have to consume. The more time they waste, the smaller the chances of running out before the troops complete the entire exercise area blockade!"

"What, I can't run out. As long as I'm surrounded, we can't search the mountain in a carpet style when it dawns, and I don't believe it, I can't find it out." Liu Fei said hatefully.

"Part mate, take out the map, we have to study it carefully. It is not a solution to search it in a while." When Qu Sen encouraged everyone, his confidence also improved a lot.

"Since it's difficult for them to escape, let's go to participate in the peripheral blockade and wait for dawn to participate in the network search." Liu Fei replied.

"If they are really spies, they must have collected a lot of information about our participating troops. Now that the unlimited network is so developed, I am afraid that where will they send away the information, it will be too late to catch them at that time." Qu Sen explained.

"Damn, you have to look for it now!" Liu Fei quickly took out the map and shook it open when he heard it.

The two divisions participating in this exercise represent the troops with the highest equipment level and technological content in China at this stage, and the other is the first batch of standard mixed divisions after completion of reorganization. The situation of these two troops is undoubtedly the most concerned target of foreign military intelligence departments.

As soon as Qu Sen said that everyone in the team realized how serious the leak would be if these information was spread.

The soldiers who were a little relaxed just now immediately cheered up and re-determined the search direction. After Liu Fei greeted him, he dispersed again into a scattered line and searched in a direction 259,260.

Due to the serious physical energy consumption of all people, Qusen's team only searched the line 262 to 263 after an hour, and there were about 20 kilometers of mountain roads from the edge of the exercise.

Liu Fei could only order everyone to rest on the spot for ten minutes.

Because of the overdrawn physical strength, no one spoke during this break. Everyone gasped for a while and began to replenish the lost water. Several soldiers with leg cramps were stretching their muscles to each other, all gritting their teeth and exerting force, and no one shouted out.

"Qu Sen, call Qu Sen." While Qu Sen leaned against a tree and pressed his calf hard to relax his muscles, Zhou Li's voice with a noise came from the communicator on his forearm.

"Received, please speak!" Qu Sen pressed the call button to respond.

"The 13-man team in the southeast of 262 is in a stagnant state, are you?" Zhou Li's voice was anxious.

"It's us!" Qu Sen realized that there was something and answered immediately.

"You immediately move to the right north and right, hurry up!"

"Yes, act immediately." Qu Sen responded and released the call button.

There was no need to greet him at all. After hearing the sound from the communicator, the twelve soldiers in the team had already stood up and started to move north at full speed.

Qu Sen previously suggested monitoring the wireless network and satellite connections in the exercise area, and this suggestion was taken seriously by the director department.

While using existing investigative methods to monitor unknown communication signals in the area, we requested the public security system to help coordinate local mobile phones and China Unicom two wireless communication companies to let their technical departments monitor wireless communication and wireless network conditions in the exercise area.

The public security system quickly issued a joint investigation notice, and the police took the joint investigation notice to go directly to the computer rooms of the two major communication companies in the city to ask for assistance. Because it involved high operating authority, the duty personnel in the two computer rooms did not dare to make decisions privately, and contacted their respective superior supervisors. The supervisor contacted the supervisor again, and the municipal supervisor fed the situation back to the provincial supervisor.

During this period, several people were contacted, and the phone was turned off due to night breaks. It was almost an hour later when the joint investigation request was finally approved. The on-duty officer in the computer room did not delay after obtaining the approval of the leader and immediately began to lock several signal towers in the exercise area.

Because the area selected for the exercise is far away from residential areas and there are not many signal towers, it is basically in a gap during the late night. After excluding the external communications of the director department of the exercise, the mobile company's computer room found a terminal device, which is continuously uploading data using the GPRS network.

After initially using AGPS positioning, it is determined that the terminal equipment is in the hilly area east of the exercise area. In that area, except for forest rangers, they will enter during patrols, there are few people usually, let alone in the stage of exercise blockade. In addition, no one will use their mobile phones to surf the Internet in the deep mountains in the middle of the night.

This suspicious situation immediately attracted the attention of the public security department, but there was a disagreement on whether to cut off the network of the device immediately.

Some people believe that in order to prevent the leakage of troops' intelligence, the network connection should be cut off immediately. Others believe that if the network is cut off now, three suspected enemy intelligence personnel are likely to continue moving, seeking a breakthrough in blockade and escape, causing difficulties in the arrest work.

However, an engineer in the mobile computer room proposed an idea: no need to cut off the network can prevent intelligence leakage.

If the wireless network in China wants to complete point-to-point data exchange, it requires many node relays. The idea of ​​engineers is to tamper with the server in the mobile computer room. When the data is transferred there, it will artificially destroy the data packet content, and at the same time reduce the network speed of the active terminal equipment.

There are three benefits in this way. One is that even if the other party sends intelligence information, the receiver will not be of any use after receiving it. Second, reducing the connection speed will extend their data transmission time, which is more conducive to capture. Third, because the mobile phone GPRS network is ultimately connected to the wide area network, and it takes a long time to track and lock the recipient of the data. If he does it according to his ideas, it will increase the possibility of locking the data recipient.
