After the police car drove out of the compound, it quickly turned right, drove onto the four-lane Pipashan Road, and then went straight all the way.

The vehicles at the intersection were crowded into knots, it turned out that the traffic lights were out of power, the traffic police whistled, directing the flow of people and vehicles, in a hurry, sweat beads hung all over the forehead, but the effect was not obvious, and it was still crowded. Liu Qing rolled down the window glass, stretched out his hand to say hello, and looked sympathetically at this good comrade with a sweaty face.

Finally squeezing out the traffic, and then turning left, there is a narrow canal road, bicycles mixed in with the traffic, street vendors pushing their carts along the street to sell oranges, and parents picking up their children vigorously honking the car horn and cursing and swearing. Liu Qing's police car plunged into the chaos, and the piercing siren cut through the traffic like a knife. Very close to the affiliated hospital, he could clearly see the white sign of "Affiliated Hospital" on the 20th floor.

After passing through the gate of the affiliated hospital, follow the newly built paint road, go straight to the left, until he saw the words "underground garage", from the downhill road at its entrance, slowly drive in, there is some darkness inside, so he turned on the headlights, illuminated the dark ring road, and continued to drive to the underground garage on the second floor.

Even on the second floor, the parking spaces are not rich, and there are cars crowded everywhere, and you can't see the end at a glance. They searched inside for a long time before they stopped next to the heating room. The two jumped out of the car, quickly picked up their things, followed the signs on the ground, and trotted all the way to the elevator room.

The elevator hall is spacious, like a rectangular box, about eighty square meters or so, and the floor is covered with gray non-slip tiles. The two faced the elevator, stood in the center of the elevator room, glanced at each other, smiled wryly and did not speak, and looked at the elevator indicator light. There was not a trace of wind in the passage, like a stuffy steamer, which made people restless.

When the "-2" indicator light came on, the elevator door slowly opened, and a lady in light blue overalls walked out, she was short and fat, her clothes seemed to be torn, her arms were exposed, her fleshy round face had a reddish fleshy nose, no different from a carrot, her eyes looked over the shoulders of the two people at the distant vehicle, and she looked listless.

"The elevator is going up, please pay attention to safety, what floor will I go to?" she was expressionless, her voice was dry, as light as white water, and there was no emotion at all.

“-1，4。 Liu Qing replied.

She looked at the two of them, lazily pressed the number keys, and then stretched out her right hand and held on to the elevator door to watch it slowly close before lowering her arm.

The elevator door quickly opened on the negative floor, Xiao Liu carried the toolbox, rushed out like a rabbit, and waved his left hand behind his buttocks, which was regarded as a hello to Liu Qing.

When the elevator reached the first floor, a stream of people poured into the elevator, and the chubby waitress shouted, "It's full!" and she muttered in disgust, "cut", and closed the elevator door.

Liu Qing was squeezed ten centimeters high, clinging to the elevator wall, like an erected gecko, and could only look at the top plate with his eyes and pant quietly.

When the fourth floor arrived, he was ejected from the elevator hall like a glass ball and rolled into the corridor on the fourth floor, sweat soaking through his shirt. With beads of sweat on his forehead, he walked directly to the monitoring room.

At the end of the corridor, is the security door of the "monitoring room", he knocked on the door, walked in, the room is very large, much larger than expected, the display screen is embedded in the east wall, about forty square meters, below is a row of white computer desks, placed several host monitors, behind the computer desk are several rotatable white chairs, a duty officer is sitting there, he is wearing a light blue uniform, hunched back, holding his chin in his left hand, staring at the monitor on the table, engrossed, completely unnoticed that someone walked in.

Liu Qing bent down, patted him lightly on the shoulder, took out his police ID card from his jacket pocket, opened it and showed him.

He looked up sharply, his mouth almost touching his police ID, and asked, "Police?"

"I'm sorry, I'm Liu Qing, I'm in charge of investigating the case of Professor Feng's missing body, and I'm here to watch the surveillance video. ”

"Great, Officer Liu, I'm Wei Guo, responsible for the maintenance of the surveillance equipment here, I'm watching the video footage of the past few days, and I didn't find the video of the missing body, could it be that it didn't fly?"

"This can't be, is it because your equipment is malfunctioning?"

"No, Officer Liu, the equipment is running normally, and it is inspected according to the regulations, everything is normal. ”

"When did you find out that the body was missing?" said Liu Qing, pulling a chair next to him and sitting beside him.

"At 3:10 p.m. yesterday, Dr. Zhang, the doctor on duty, went to the morgue to inspect and inadvertently found that Professor Feng's body had been replaced with a plastic model. ”

"Inadvertently?"

"Yes, I haven't heard of anyone who lacks virtue to do such a thing, so no one pays attention. ”

"It's late to report the crime, what's the reason?"

"First, we don't believe it, everyone thinks that we have remembered the wrong bed, so we took the file in a panic, and looked for it for a long time, and only reported it level by level after we were sure. As for when the case was reported, it was decided by the leader patting his head, and it had nothing to do with the soldiers. ”

"yes, I see. Now the most important thing is that we want to find out the exact time when the body disappeared through the video. ”

"Yes, I thought so too, but there are so many video files that I can only fast-forward and watch them, so I haven't finished watching them yet. ”

"Well, let's divide the work, I'll watch the first day, you watch the second day, and finally we'll watch the third day together. Liu Qing said.

"Okay, okay, that's a good idea. Wei Guo nodded.

Wei Guo turned on a host next to him, called up the video of the first day, clicked play, sat back in his chair, turned around, and checked the video of the second day.

Liu Qing checked at ten times the playback speed and found nothing suspicious. Then, he set it to play at five times the speed, and there were still no major discoveries. He looked down and thought for a while, thinking that the time when the body was stolen should be after midnight, that is, in the dead of night, when the attendant was prone to sleepiness. Thinking of this, he set it to triple the broadcast speed and carefully checked it from zero o'clock.

Sure enough, at two o'clock in the middle of the night, the two figures flashed by and disappeared from the picture in an instant. Liu Qing hurriedly turned the video back to a section, slowed down the broadcast speed, held her breath, and kept her eyes glued to the screen.

"There is a situation, come and see!" Liu Qing exclaimed excitedly.
