"Eh, I forgot to press the elevator, how many floors do you live on?" Liu Chen remembered that both of them had forgotten to press the elevator and had been in a static state before.

Qin Si said lightly: "7th floor, 701." ”

Liu Chen pressed the 7th floor, and a few seconds later, the elevator door opened, and a strong light burst in in an instant, followed by a completely different air, which instantly made Liu Chen more sober, he blocked the elevator door, this time he did not take the initiative to step forward to support Qin Si, in the atmosphere at this moment, try to avoid physical contact as much as possible.

Qin Si was stunned for a moment, but she quickly reacted, she snorted and walked out of the elevator carefully.

Qin Si took out the key from her bag, and after opening the door of the house, a peculiar smell came to her nose, and she subconsciously reached out and waved it in front of her nose.

Liu Chen followed in, he sniffed with his nose, this was not the smell of decoration, but a smell of burnt plastic, and he asked Qin Si in front of him, "You won't plug in the electricity at home, right?"

Qin Si shook his head and said, "Impossible, I basically haven't been here to live, how can I plug in the electricity." ”

Curious, the two walked into the house, looking for the reason for the smell of plastic. Liu Chen walked through the living room, came to the dining room, looked at nothing unusual, and walked into the kitchen again, and found that there was smoke coming from a power socket for boiling water, and a pungent smell of burning plastic rushed out, Liu Chen immediately turned off the power, and used a wooden chopstick to pull away the burnt wire, and the water in the kettle had been steamed dry.

"Someone from your family has been here!" Liu Chen said solemnly.

Qin Si rushed over when he heard the sound and saw a scene in the kitchen, the burnt wires were peeling off on the stove, and the kettle had been blackened by electricity, the scene was very thrilling, if Liu Chen hadn't cut off the power supply in time, there might have been a fire incident.

"How could this be, who broke into my house?" Qin Si exclaimed.

Liu Chen immediately quickly recalled in his mind the various signs he found when he walked in from the beginning, the vague footprints and residual sand at the entrance of the door, as well as the furnishings of the TV remote control in the living room, and the position of the table in the dining room, all of which happened to be the appearance of people after they had used them, plus the tea leaves and water cups opened on the table, the people who came here must have wanted to make tea in the kettle, but because of something temporary, they suddenly left, so that they forgot the water that was still boiling.

"This person should have left an hour ago, do you have surveillance here?" Liu Chen turned his head to look at the panicked Qin Si.

Qin Si nodded and replied, "There is surveillance, but only in the aisle." ”

"I'm going to check it out now. ”

Because Qin Si's movement was not very convenient, Liu Chen asked her to stay in the house and go downstairs to find the property to check the monitoring. Liu Chen explained that he was Qin Si's friend, and to find the surveillance on the 7th floor, the property security guard took Liu Chen to the monitoring room.

After getting the permission of the security guard, Liu Chen took the initiative to operate the monitoring screen, he adjusted the monitoring to the screen on the 7th floor of Building 11, the time was pulled to an hour ago from this time, and slowly pulled the progress bar back, except for a resident on the opposite side who was in and out, he didn't see anyone coming out of Qin Si's house.

Liu Chen felt very strange, he believed that his judgment would not be wrong, the person who entered the house must have left an hour ago, and the pot of water must have been boiled by him, if he left temporarily, it should not be designed so precisely, isn't it through the door?

Liu Chen made a phone call to Qin Si and asked, "In addition to the main entrance, where else can you enter and exit your house?"

Qin Si looked at the door of his house, looked around again, and said, "There should be only one door, and the other is the window, it is impossible for that person to pass through the window, this is the 7th floor, it is too dangerous." ”

Liu Chen thought for a while and said, "You go out and have a look, see if there are other passages to enter and exit your home, and see if there are any footprints on the load-bearing beams outside the corridor to see if there are any footprints or something." ”

Qin Si followed Liu Chen's command, got up and walked carefully to the door, then opened the door and walked out, going to the public corridor outside to see if there was any possibility as Liu Chen said.

Liu Chen didn't see Qin Si's figure for a long time, and asked into the phone, "Did you go out to see?"

Qin Si replied, "Are you out?"

"Why didn't anyone see you?"

"Huh?

Suddenly, Liu Chen saw an unexpected picture in the surveillance, he did not see Qin Si's figure in his own surveillance screen, but saw Qin Si's figure in the surveillance screen on the 17th floor.

"Why did your picture appear in the surveillance screen on the 17th floor?" Liu Chen exclaimed at the surveillance screen.

"Huh, how could it be ???," Qin Si was also surprised.

Liu Chen carefully looked at the floor markings of the two surveillance videos and confirmed: "I took a look, your figure did appear in the surveillance screen on the 17th floor, and you are actually on the 7th floor, that is to say, the monitoring on the 7th floor and the 17th floor have switched positions, which can be explained." ”

It was the first time Qin Si encountered this situation, and it was still in his own community, and after listening to Liu Chen's analysis, he was still in disbelief: "No, there is such a thing?"

Liu Chen judged: "It should have been a mistake when installing the monitoring, and I will now check the monitoring on the 17th floor." ”

Liu Chen immediately switched the monitoring screen, and the main screen came to the 17th floor, Liu Chen still pulled back for an hour according to his own judgment, and then carefully pulled the progress bar.

Finally, when the progress bar was pulled to a third, a figure appeared in the surveillance screen and walked out of Qin Si's house.

This figure is obviously a man, he is wearing a mask and a peaked cap, the hat is pressed very low, as if he is deliberately avoiding surveillance, and his height is about 180, judging by his figure, he should be in his thirties.

Liu Chen didn't know the man, but he said hello to the security guard and saved the video. After looking at other clues, he found nothing new, so he said goodbye to the security guard and returned to Qin Si's house.

Liu Chen knocked on the door, Qin Si came over and opened it and asked, "Did you find anything?"

Qin Si's tone and expression could be seen to be very nervous, his home was broken into by an unknown person, this is a very dangerous thing, in case the other party is a heinous robber, the consequences are unimaginable, the so-called not afraid of thieves to steal, just afraid of thieves, Qin Si is afraid that he will be targeted by someone.

Liu Chen closed the door after entering the house, and said as he walked inside: "I have discovered, do you know who this person is?"

Liu Chen sat down on the sofa, took out his mobile phone from his pocket, and played the copied surveillance video to Qin Si.

Qin Si picked up Liu Chen's mobile phone and carefully looked at the footage taken in the surveillance, she saw a man of one meter and eight feet, who walked out of his house in strict disguise, and carried a backpack.

The surveillance footage is only five seconds long, and it's over before you can recognize it. Qin Si froze several of the pictures and zoomed them in, but the enlarged pictures were very blurry, and at this time she regretted very much that she did not install a high-definition camera, and suffered a loss at a critical moment.

"Do you recognize it?" Liu Chen asked as he looked at Qin Si.

Qin Si pouted and shook his head, "The picture is too blurry to be easy to identify." ”

Liu Chen prompted: "You can go through some other characteristics, such as walking posture, body proportions, backpack color, etc., not necessarily through facial details. ”

Qin Si pulled the progress bar to the front again and started to look at the picture again, and Liu Chen was also on the side to help identify it.

"I think I've seen this shoulder bag color somewhere......"

Qin Si's thoughts drifted back to a plot three years ago.

At that time, Qin Si's husband Liu Muchu had not yet encountered a car accident, and when the couple was dining in a hotel, they met Hu Bingcheng by chance, and Hu Bingcheng was also dining in the hotel.

Although the two companies are competitors and the relationship is not very good, but when they come face to face, the big scene still has to be taken care of, Liu Muchu nodded to Hu Bingcheng and greeted: "Mr. Hu, what a coincidence, you are also here." ”

"Yo, isn't this Mr. Liu, take your wife out to dinner. Hu Bingcheng's gaze shifted from Liu Muchu to Qin Si, "The boss lady is getting more and more tasteful, Mr. Liu is really blessed." ”

Qin Sibai glanced at Hu Bingcheng and said sarcastically: "How can our old Liu be so blessed as Mr. Hu, I manage him strictly, unlike Mr. Hu, the red flag at home does not fall, and the colorful flags flutter outside." ”

As soon as Hu Bingcheng heard this, the smile on his face immediately put away, his face was embarrassed and ugly, and at this time, one of his subordinates wanted to rush up to teach Qin Si a lesson, but was stopped by Hu Bingcheng.

Qin Si noticed that this man was dressed like a bodyguard, but he was carrying a shoulder bag crossbody, which concealed the bodyguard temperament on his body a little, and it was difficult to guess his identity if he didn't look carefully.

Later, they met Hu Bingcheng a few more times, and this backpack man was present every time, with different hairstyles and clothes, but the only thing that remained unchanged was the crossbody bag, which was always inseparable, and it seemed to contain very important things, maybe even weapons.

Linked to the mysterious man on the surveillance screen this time, the familiar crossbody bag made Qin Si have to link this matter with the mysterious man and Hu Bingcheng.

"This person seems to be one of Hu Bingcheng's subordinates. Qin Si guessed based on his own analysis.

Liu Chen stared at the man on the screen and asked, "Hu Bingcheng's subordinates, why did he come to your house?"

Qin Si shook his head slightly and said, "I don't know, I have to ask him." ”

Liu Chen put away his phone and asked, "Where is he, let's go find out the situation." ”

Qin Si turned his head to look at Liu Chen: "Are you really going to look for him?"

Liu Chen said with a solemn face: "If this matter is not solved, can you live in this home with peace of mind? In case a camera or something is installed in it, this is not a trivial matter." ”
