Looking up at the sky in the drizzle, it sounds very artistic.

But in reality, if you see such a person on the street or at night near 10 o'clock, most people will probably think that the other person is either mentally ill or mentally stimulated.

Obviously, in the old city before the station tonight, the sparse pedestrians in the rain, whether walking or riding, looked normal. Not to mention standing in the dark night and looking up at the sky, there was not even walking in the rain.

In fact, even if someone looks up, it is difficult to find three drones with black paint and flying at a height of nearly forty meters.

"The second plane found a suspected target and is further determined." Li Ying's voice sounded in the command car.

The five people in the command vehicle and the police officers in the municipal bureau command center were also shifted their eyes to the screen of the No. 2 machine on their respective monitor walls.

Under night vision camera, a man wearing a dark poncho and riding a dark bicycle was slowly riding in the rain.

Li Ying controlled the drone to accelerate with her left hand and flew to the front of the cyclist. At the same time, she adjusted the high-speed camera with her right hand, and after locking the target, the lens automatically adjusted the focal length.

When the cyclist was about to pass a dim street light, the high-speed lens feedback came back to the cyclist wearing a red poncho, and there were several long bangs wet with rain on his forehead hanging down.

"It has been ruled out, the target is a female, and the No. 2 aircraft continues to search." When the command vehicle and the people in the command center saw the characteristics of the cyclist clearly, Li Ying's voice sounded again. At the same time, the picture of the No. 2 aircraft also moved from the cyclist and wandered back and forth in the small courtyards on both sides of the alley.

Although no suspect was found, the leaders of the municipal bureau in the command center and the members of the evaluation team watching on the side had fully felt the efficiency of the three drones.

Especially the leaders in charge of the criminal investigation, all of them began to feel itchy, thinking about when this thing would be truly distributed. With this game, Ying'er tracking, locking, and investigating from the air, how much trouble the grassroots investigators have to save.

Especially the response speed of the investigation drone is indeed a good thing that can greatly improve the efficiency of field case handling.

"The report of the No. 1 aircraft, suspected target was found in the courtyard of No. 46, the eastern section of Beiyi Hutong." About three minutes later, Qu Sen's voice sounded at the same time in the command vehicle and the speakers of the command center.

In the surveillance screen of the No. 1 unit, a man in a raincoat was walking through the yard and heading towards the door of the main building in the yard.

The yard was very small. When Qu Sen adjusted the drone position, the man had already walked through the yard and stood in front of the door. Then he took off the raincoat on his body and held it in his right hand, put his left hand into his pocket as if he was taking out the key.

Qu Sen moved the drone to hover above the courtyard gate, and the high-speed camera locked the man's back.

Soon, the man took out the key from his pocket, opened the door and entered the room. The moment he turned around and closed the door, the high-speed camera captured his side face with his head slightly lowered. After the door closed, about two seconds later, the lights in the room were on.

Qu Sen controlled the drone to maneuver around the house, looking for a perspective where you can see the indoor situation, and the commander's car had already begun to compare the side face he had captured before with the photo of Huang Ansheng.

Because there are too few facial features in the photo, the photo comparison system cannot recognize it, but if you look visually, the two are at least five points similar.

"Car No. 1 requested to get close to the target building and use the technical reconnaissance drone to confirm further." Qu Sen controlled the drone to fly around the house twice. After not finding a suitable perspective, he picked up the hand table and issued a request.

"Agree, you can drive the car to the junction of Wenying Road and Beiyi Hutong to find a suitable location to let it fly." The figure of the commander on the scene was heard inside the commander.

"Received, Car No. 1 will be in place immediately." While Qu Sen responded with the hand table, the off-road vehicle driver had already started the car and drove towards the junction of Wenying Road and Beiyi Hutong.

Since it was still impossible to confirm whether the target discovered by Qu Sen was Huang Ansheng, No. 2 and No. 3 drones were still searching within the range marked by the command vehicle.

The No. 1 car Qu Sen was riding in and parked it at the intersection. The No. 1 drone returned quickly because there was a lot of water on the ground around it, so it landed directly on the roof.

While Liu Zhiquan got out of the car and took back the No. 1 drone, he placed the technical reconnaissance drone on the roof. Then the drone in the fuselage quickly took off and flew directly to the direction of the house where the suspected target was located.

The technical reconnaissance drone with a diameter of less than 11 centimeters quickly found a suitable observation location. However, although the suspect in the house was walking back and forth and making phone calls, he could not capture his face.

Moreover, due to the interference of the glass and the sound of rain, it was impossible to collect the sounds made by calling in the house. A few seconds later, the person in the house hung up the phone and turned directly into the room on the east side.

Qu Sen controlled the drone to approach the window on the east side and found that the curtains were blocking very tightly. He could only see figures projected on the curtains. After swaying indoors for a while, he seemed to be lying down, and then he could no longer capture effective information.

Qu Sen simply controlled the drone to cruise the front of the house, and soon found that the open air window that could be lifted up in the west room was open. Although it was only half open, the technical reconnaissance drone could fly in.

After adjusting to the appropriate height in the air, the technical reconnaissance drone flew directly into the house through the ventilation window at an elevation angle.

"Brother, don't worry, now I've been checking the cameras that are lost on the street and I don't have time to stare at us."

...

"Look, I rode my bike around and entered the yard. I lie on the crack in the door for a while. It was raining, and there were no ghosts outside."

...

"I just called Xiao Dongbei and asked him to drive over after a little while. Well... well... don't worry, I'll deal with my phone, MP3 and so on. If I can't hold those things, I'll lose a lot of the market after half a month."

...

"Okay, I'll ask Xiaodongbei to send me a fortune. Just pick me up at around two o'clock... It's so bad, I'm dead."

There was no interference in the house at all. The sound signals collected by the technical reconnaissance drone were very clear, but the other party spoke in dialect, and Qu Sen basically couldn't quite understand it. However, Deputy Director Xiao could understand it. While listening to the voices sounded from the laptop speaker, he whispered into Mandarin and said it to Qu Sen.

"Who is Xiaodongbei?" Qu Sen asked in a low voice when he heard no more sound in the house.

"The big name Zhang Wenren grew up at the grandmother's house in Changchun when she was a child. She came back in middle school. There was a micro bread, and now she is working around the lamp city all day long." Xiao Dongbei's personal information came to Xiao's deputy director Xiao said.

"You judge whether the one in the east room will be Huang Ansheng?" Qu Sen asked again.

"Ninety percent!" Deputy Director Xiao said 90 percent, but judging from his expression, he had already determined that the person in the east room was Huang Ansheng.

Compared with Deputy Director Xiao's optimism, the people in the command center should be more cautious. They judged that 70% of the suspects Qu Sen captured were probably Huang Ansheng.

However, even if the person in the house is not Huang Ansheng, the analysis of the content of his previous call is definitely not a good thing, at least he is a merchandise or electronic waste.

Given that the best tracking time limit has passed since the informant discovered Huang Ansheng, even if the suspect Qu Sen locked is not Huang Ansheng, he has now entered a certain building.

The on-site command issued an order, and the No. 2 drone immediately went to the top of the suspect's house to monitor the outdoor environment. The No. 3 drone returned and replaced the battery when the No. 2 drone was insufficient to replace the position.

There is only a certain gap below the door of Qu Sen because the door of the east house is placed in the door curtain. However, the gap height is only about three centimeters, and there are extremely dense ears under the door curtain, so the risk of the drone sneaking into the house is too high.

After observing for a while, Qu Sen simply parked the drone on the beam on the roof of the main hall, turned off the rotor and lens to save power, leaving only the sound pickup assembly still working.

About ten minutes later, a snoring sound came from the house. Everyone in car No. 1, including Qu Sen, all listened carefully to the suspect's snoring sounds that sometimes didn't dare to be careless at all.

Above the roof outside the house, about fifteen meters high, the No. 2 drone was hovering quietly in the drizzle. The high-speed lens under the fuselage was slowly rotating, constantly capturing the movements around the house.

On the other hand, the command center is deploying to investigate peripheral information.

Previously, two people were obtained through monitoring: "Xiaobeidong" and "Faocai". The basic situation of Xiaobeidong was consistent with what Deputy Director Xiao said. Another person named "Faocai" did not collect consistent information for the time being.

The suspect's house is named Yu Shengshui, who does seafood wholesale and is registered in the old city. He bought a building near the Chengnan Seafood Market a year ago, and the houses in the old city have been idle.

When the police inspected the comprehensive situation of the film, the information collected was that Yu Shengshui had always hanged the old house in the real estate agency, but the rent was high and he had not rented it for more than half a year.

When the time was near 1:00 a.m., more than 30 fieldworkers from both branches and thirteen vehicles were all on standby. The No. 3 drone took over the reconnaissance mission of the No. 2 drone. After the recovery and confirmation function of the No. 2 drone was intact, the battery was replaced and the departure was set off again.

After more than two minutes, hovered three blocks away from the target location, above the Xiaodongbei home.

At 1 a.m., the lights on the room of Xiaodong's house were on. Five minutes later, a young man walked out of the house. The police made a special judgment on the appearance captured by the drone lens. The man was Xiaodongbei.

After being discharged from the hospital, Xiao Dongbei got on his minivan directly, and then the car started and the direction of travel was exactly the direction of the suspect's house.

About ten minutes later, Xiaodongbei drove past the off-road vehicle that Qusen was taking and drove into Beiyi Hutong. Soon, he stopped outside the courtyard of the target house.

Suddenly a ringtone of the cell phone rang in the laptop speaker. Qu Sen immediately restored the power of the drone when he heard the sound and turned on the camera. Because he was worried that if the startup was too late, the whereabouts of the dust stirred by the rotor would arouse the suspect's alertness.

The drone parked on the beams in the main hall, four rotors began to work at the same time, and the fuselage slowly lifted up.
Chapter completed!
