It was the first time I felt so comfortable with my feet on the ground, and I was sure that the killer couldn't have done something like that at that height unless he was a pervert, four times in a row.

Xiaowen immediately came up to help me unbuckle and said, "Brother Qiao, what have you discovered?" ”

"Let's go back and go to the scene of the crime. There's something on the outer wall, can you lend us this dress?" I shouted at the swarthy man and Zhang Jian in the distance.

"Of course, comrade policeman. Have you checked it out? It's none of the same with us, right? Supervisor Zhang trotted over and said.

Xiaowen looked at me and said, "Brother Qiao, what are you doing here?" ”

"You'll find out later, by the way, can you borrow a few more meters of rope?" I said that I then sent a copy of the shooting to the director by MMS, and the content notes were found.

。。。

When I returned to Building 707 in Wutong Community, Dongcheng District, I put on my aerial work clothes and gloves again.

After connecting the ropes, he handed it to Xiao Gao and said, "How much do you weigh?" ”

"What's wrong with Hundred Fourteen?" Xiaowen said.

"You're tied to yourself with this head, and I'm going out the window with a dead knot. There's something out there, and I'm going to take it off. I said, handing over the rope.

Xiaowen was tied around his waist, and after the lock was firmly fastened, there was still a distance of more than a meter between me and me.

I came to the window, and Xiaowen was also brought by me.

I climbed out of the window, leaning against the wall Xiaowen shouted on the other end, "Brother Qiao, hurry up." ”

Up and down, left and right, I took off the four boards and threw them into the room.

Then he shouted to Xiaowen: "Pull me back." ”

Xiaowen pulled me back into the room, and I put the four signs together.

In the center of the sign is a reflective strip, surrounded by a wall-colored ornament that protrudes from it.

The reflection can only be seen when viewed from the front, and it will be blocked by decorations if it is slightly sideways.

As a result, only parallel angles can see the entirety, and no other angles can be seen.

This also results in not being viewed from a specific angle, which will not be found at all.

Xiaowen stretched out his hand and said, "Brother Qiao, what is this thing?" ”

I immediately grabbed Xiaowen's hand and said, "Don't touch it without gloves, maybe the murderer left fingerprints or something." ”

Xiaowen was startled and withdrew his hand.

I pointed to something and said, "You must know the QR code, right?" ”

"What's wrong?" Xiaowen said.

Sticking the four signs into squares, I pointed to the inside of the frame and said, "The phone can recognize the QR code with the camera, and you can also use the camera to recognize this reflective frame." As long as the code is written and face recognition is carried out within the box, a headshot becomes extremely easy. ”

"This? Is it a machine that kills people? Can it be a drone in mid-air? Xiaowen said.

"I guessed the same thing before, and now I seem to be able to confirm it. We ran the remaining three sites, and we had to go before the evening to see if there were any of these things. I said.

Xiaowen nodded, and I went downstairs to ask for a ziplock bag from a nearby stationery store to wrap things up.

Xiaowen wants to take me to a taxi. I thought about asking Xiaowen to go to the police station to ask for a car.

After all, I can drive, so I can't just rely on a bicycle taxi to investigate the case.

returned to the police station and handed the ziplock bag to Xiaowen.

Ask Xiaowen to find an appraisal that can be identified, and ask Xiaowen to find a car.

Xiaowen inquired for a long time, and the appraisal was solved, but the car was never available.
