Bai Song did not expect that there would be such unexpected gains.

　　 At that time, almost everyone's energy was concentrated on the scene of the crime. No one would pay attention to the crowd of onlookers around, but now think about it, among the crowd of onlookers, more or less there may still be problems.

　　 Even, Bai Song just took a look and saw the figure of the farmer captured today from the key pictures compiled by Zhao Xinqiao!

　　 This person was indeed at the scene at the time, and the person who followed Bai Song should be him.

　　 Sinking down, Bai Song analyzed it carefully, and pointed to the computer screen: "The person you marked, we caught today."

　　 "Who is he?" Zhao Xinqiao was a little confused: "You didn't tell me what important person was caught today."

　　 "I don't know if he is an important person, but if there is this video, he is 100% problematic." Bai Song continued to look at a few pictures: "How did you find this person has a problem."

　　 "The gait and demeanor are not normal." Xinqiao pointed to the other photos, "Look at the corresponding video, this person is nervous."

　　 "Nervous?" Bai Song looked at the video and nodded: "It is true, but if you are nervous, it means that he is really not a key person. That is, I don't know what he is the breakthrough point."

　　 "Well, look at this person again." Zhao Xinqiao pointed to the second person, "This person has seen the person you just mentioned for several times, and he also wears earphones."

　　 Bai Song opened the second set of photos and looked at the video carefully.

　　 After all, there are limitations on the definition of mobile phone video. If you just watch it once, it is impossible to see everyone's status. All these photos are extracted from the video and have been highlighted.

　　 The horizontal angle of view of human eyes can see 188 degrees, but the angle of focus is only 25 degrees, and if you stare at one point intently, you can only observe one character in the whole video at the same time.

　　 In other words, don’t watch this video for more than 20 minutes, but if you want to analyze it carefully, you can watch it for a long time. Zhao Xinqiao has watched it many times and counted them.

After looking carefully for a few minutes, Bai Song found out that this man was indeed a problem. He had "inadvertently" seen the farmer twice, and he was also wearing headphones and talking with his mouth, although he could not hear what he said. , But what is certain is that he is not talking to people around him.

　　 The video is still not clear enough. If you don’t stare at this person carefully, there will be no delivery.

　　 Bai Song changed the angle of view to the farmer again, he couldn't see whether he was wearing headphones or not.

　　 "Will it help you?" Zhao Xinqiao asked.

　　 "Yes, and it's very big." Bai Song was very grateful. After watching these videos, he was very moved. He stood up and prepared to hug Zhao Xin Bridge.

　　 "Get up, go and work on your case." Zhao Xinqiao pushed Bai Song away, then turned and went into the second bedroom, "Don't be too anxious about this matter, I won't think too much."

　　...

　　 Bai Song watched Zhao Xinqiao go to the next door, and looked at the computer for half a minute.

　　 Would you like to call Wang Liang again to show off his affection?

　　 I heard that Ma Zhiyuan's younger sister and Ma Zhiyuan are not the same character. It may be that Ma Zhiyuan loves her sister very much. Her sister is a good student, but her character is still a little girl. A love relationship will almost exhaust Wang Liang.

　　 Forget it, let's be a man.

　　 Bai Song thought for a while, and directly sent the second person's photo to the mobile phone of Qin Detachment, and then called Qin Detachment to talk about the situation.

　　 "Is this a farmer's superior?" Qin Detachment asked.

"The farmer didn't speak from start to finish, and he said it several times, and it looked like he was instructing the peasant. Every time he finished speaking, the peasant would look at it a few more times." Bai Song explained: " The video is too big to be sent from the mailbox. I will put it in the network disk for a while."

　　 "Okay, send it here for us to study and study." Qin Detachment said: "This discovery is very important, maybe this is the key to the case, who discovered this?"

　　 "Um, my girlfriend." Bai Song paused for a few seconds, and decided to tell the truth.

　　 "Your girlfriend?" Qin Detachment really didn't expect this time: "Okay, you're a little good... I see, uh, keep it secret."

　　 The style of painting changed a little, and Bai Song coughed slightly, "Don't worry... Uh, Qin Detachment, I have one more thing to say."

　　Qin Detachment may have been choked by Bai Song's words just now, and he hummed softly, wanting to hear what Bai Song was about to say. New 81 Chinese network update the fastest mobile terminal: https:/

"That's it. The farmer we caught today, his mobile phone is very clean, and there is no earphones, I suspect one thing, they are not using our 2G to 4G network communication, but using them. The radio waves built by myself were connected." Bai Song said: "I just thought that when I was in Tianbei District, I met the bald heads and the others, and I happened to meet them to go to the factory at night. This is not accidental.

　　 It is very likely that these people install these devices. Although they can indeed control black radio and other devices, they can also be used for their own communication. This kind of communication will hardly be discovered as long as we don't know it in advance.

　　 So ~lightnovelpub.net~ Tianbei District itself has some similar equipment, but after I went to the Economic Investigation Corps, they grasped my whereabouts and went there to temporarily install one.

　　This kind of equipment must still be available in Jiuhe District. I think we can take technical measures to counteract it. Maybe we can find some illegal channels and find some necessary things in reverse.

　　 What I consider is that if we find out, we can monitor it first, and don't rush to get rid of it. "

　　 "Okay, hurry up and send the video over." Qin Detachment heard Bai Song's words and became serious: "You have a good rest at home, I know about this."

　　 Hanging up the phone, Bai Song manipulated it, and sent the video and some photos organized by Zhao Xinqiao to a network disk, and then gave the Qin team the account password, and he leaned on the bed.

　　 After thinking about it for a long time, Bai Song couldn't sleep a bit, so he moved the binoculars out of the balcony and looked around in his spare time.

　　 Someone in the community is looking at him Ruoruowu?

　　 Bai Song suddenly became nervous, is there still someone watching him? And know which household he lives in?

　　 Secretly pointed the telescope at the person, slowly focusing...

　　 Uh? Isn't this the grandson of the second team? Starting

　　 Bai Song took a closer look, really!

　　 My god...

　　 Bai Song then looked around with his binoculars, and found a familiar figure.

Ugh...

　　 This is the group I love deeply...
