The black policeman’s face kept changing, but it was so dark that no one could see any change.

Until the end, he snorted coldly and said, "Stop talking nonsense and wasting time again. Take out the surveillance data as soon as possible."

Zhang Lingjun smiled, and then led the two of them into the room and came to the only table.

He casually threw some unsightly leftovers on the table into the trash can, then opened his laptop and called up the video of Ruan Xing's room recorded through Ruan Xing's computer last night, "Well... this is it, freshly baked, without any

Impressed."

Zhang Lingjun asked: "Where do you need me to send it? There are also previous surveillances, all of which are still saved. If necessary, you can send them all together..."

The black policeman frowned and thought for a moment, then said, "Just open it."

Zhang Lingjun asked: "Are you looking at it from the beginning?"

What I’m talking about from the beginning is of course the time up to the last time Zhang Lingjun was monitored.

The black policeman took a look at it for more than 20 hours, but it was not enough time to see it all.

So he said: "Those not-so-important monitors can cut out multiple screens and fast-forward multiple time periods. As long as there are no problems, our main purpose is to find out how Ruan Xing died last night. What happened at that time

What, who is the murderer who committed these crimes?"

Zhang Lingjun nodded: "No problem... The time when I conflicted with Ruan Xingqi last night was probably a little after 6 p.m. Based on this time, she should have returned home around 6:30..."

As he spoke, he cut the surveillance video into 9 video fragments from the last place he saw it to the time before Ruan Xing returned home at 6:30, and then played them in synchronized fast forward on the screen in the form of a nine-square grid.

I saw nine identical pictures, which seemed to be pictures, arranged on the screen as if they were still.

This is a standard urban village low-cost house similar in style and size to Zhang Lingjun’s.

But the appearance inside gives people a completely different feeling, with snow-white walls, beige wardrobe against the wall, light green floor tiles, desks of the same color, shoe racks, paper baskets... Everything carefully selected is neatly placed.

Clean and a little warm and cute.

But after watching it for a long time, it seems to be an illusion. Suddenly, you will have a feeling that you shouldn't have when facing this picture, a depressing and bad feeling.

Old John frowned and said, "Is it because you already know the outcome, so you feel uncomfortable?"

Zhang Lingjun shook his head when he heard this, "No, I have felt this way before, but in the end I found out that it was because this very clean room was a little dirty."

"Dirty?"

Old John looked at the neat and clean room in the surveillance camera and couldn't help but feel a little curious, so he searched the screen carefully, and finally found that there were some faint black traces in the corner of the wall, forming some kind of regular rings, on the wallpaper in the corner from the ground.

"That's..."

"It was moss or plaque or something."

The black policeman on the side explained: "Because the room has no lighting at all and is too dark, it is very common and can be found in many places."

Old John was a little skeptical, "How are you sure it's plaque? You can't see it clearly from such a distance. That shape might be some kind of symbol."

The black policeman pointed to the window of Zhang Lingjun's room, "Because there are some here too."

In the innermost part of the rental house, outside the kitchen window that can only accommodate one person, and on the wall of the opposite building that is almost close to each other without any light coming in, there are some black ones attached sporadically, in circles that look like concentric circles.

It is the attachment of moss.

Zhang Lingjun said: "These plaques just appeared in the past two years. I heard that they seemed to be invaded by some foreign organisms, which came from Australia. They are everywhere in Xiacheng District. It is indeed quite common..."<

/p>

Old John frowned and said, "Ordinary plaque, even if you don't notice traces in the monitoring, you will hardly notice it. Why does it make people feel uncomfortable?"

Zhang Lingjun thought for a while, "Maybe it's because it's too obtrusive. The cleaner the place, the more noticeable it is if it's dirty. If it's a room like mine, it definitely won't feel like it.

“Then this conspicuous mildew stain appeared on the wallpaper that was supposed to cover the blemishes.

"This has the opposite effect, making the original cleanness feel like a castle in the air. It makes people feel that this mildew is just the tip of the iceberg. There may be more in invisible places, under the wallpaper, inside the walls, in

It felt like the water pipes were crawling everywhere... and this gave rise to a sense of psychological discomfort.

"Similar means were used in some ancient Feng Shui layouts to harm people and affect their spirits, thus affecting their health. In modern times, this situation often appears in negative examples of house design and decoration classes. It is a normal phenomenon.

Science can explain it, so don’t be surprised.

As he spoke, he looked at the two people beside him and explained: "Because of my previous job, I have a little knowledge of Feng Shui and decoration design..."

While the three of them were talking, the monitoring time came to 18:32:31.

Suddenly, bang bang bang... the friction and collision of the key and the door, and the friction and collision of the key chain itself sounded in the silent surveillance.

The three people outside the surveillance area immediately calmed down and cheered up.

Crunch…

The dark red security door opened inward, and a woman walked in carrying a lunch box.

It is Ruan Xing.

After she entered the door, she turned around and closed the door, locked it inside, and then fastened the iron chain door bolt to secure it. Then she placed the lunch box in her hand on the shoe cabinet next to the door, bent down and carried the shoe cabinet with both hands.

Lean against the door and block the door.

It looks like he is guarding against someone.

But the strange thing is that there is no panic or worry in her expression and movements.

After calmly blocking the door, he clapped his hands, took off his coat and clothes, hung them up neatly, put on his slippers, Shi Shiran picked up the lunch box, and came to the desk with the function of a dining table.

As if nothing was wrong, I started eating.

After eating for a while, I even took out my mobile phone and browsed short videos while eating.

Although the mobile phone screen cannot be seen clearly from the surveillance camera, through the distinctive voice——

First there was a fragment of American country music with a loud volume. After about a minute, the music changed to electronic music. Then it was an original song with obviously Japanese-style lyrics and third-rate ancient lyrics. After half a minute, it turned into a song accompanied by canned laughter.

Embarrassing Theater…

The content speaks for itself.

Then I watched videos while eating, and various videos kept looping.

Time passed by little by little, and the meal was finished without stopping. Just when the three of them were a little irritated and couldn't help but want to scold the short video garbage algorithm for controlling people, the electronic music DJ that was playing suddenly stopped.

Then there was a vibrating sound and a classic cell phone ringtone from a certain factory that sounded like a clear spring.

Phone!
