Of course, it is impossible for a good store to be stolen for no reason.

It is even more impossible for such a good surveillance video to disappear from the computer for no reason.

The only possibility is that someone has cleared up all possible clues before the crime.

"How many days ago?" The convict grabbed the poor employee and questioned carefully.

"Three...... Three days ago, yes, three days. ”

"It's the day before the teacher's birthday party." Lin Chen's color changed slightly.

If the previous investigation still made him feel as if he was groping in the dark, unable to see where they were, then of course the situation was still dark now, but he suddenly realized that they had actually been staying in a tightened pocket, someone had already tightened the mouth of the bag, and their struggle was only within a very limited range.

"Before the children under the banyan tree committed suicide, the other party had already begun to erase the evidence, and they were really well prepared." Xing Conglian didn't have any look of frustration, he even felt that this was a matter of course, "Oh, no, this can't be said to be fully prepared, it should be said that the fundamental purpose of this qiē is to destroy the corpse?" ”

Why did an organization that had been hidden for years, using students to make countless dark livelihoods and profiteering, run so low-key, why did it suddenly make all those big news of mass suicide?

They should know better than anyone that once they surface, there is no turning back, no matter what their final big goal is, as long as it is a serious social incident, the police will always investigate it to the end, and it is only a matter of time before they can find out thoroughly......

Well, in fact, Xing Conglian was not wrong, the six students who died, even including his little sister, were just discarded as a burden, as if they were dealing with those videos, and there was probably no more neat way than to directly "delete" them.

So this qiē is a means to clear the evidence that the entire organization once had deposited, but even so, they don't even forget to use this last chance to make money, which is probably not simply cold-blooded.

Lin Chen suddenly remembered the question of the dynasty.

Have you ever seen a world of great evil?

It's really, too sharp.

He rubbed his face vigorously, as if a brief moment of darkness could wake one up.

Then, he heard the voice of the torturer company ringing in his ears: "Let's go, let's go to the store and have a look." ”

The young man's voice was so calm and calm, and there was no frustration in being preempted.

"I've asked the dynasty to come over and see if the surveillance can be repaired, but three days have passed, and the possibility that the hard drive has not been overwritten is very small, and they won't be so careless, so be prepared if they can't find it."

Lin Chen nodded, and took one last look at the star-marked shop on the floor plan.

It's not much different from what I imagined.

The café where the people went to the empty building was not big, located in the corner of the entire underground mall, like a cold beauty in an isolated corner, in fact, that shop pù is indeed too cold now.

Its glass doors are closed, the shop is black and hollow, and the lights of the walkway illuminate a wood-colored floor near the glass door and the unmovable wooden bar next to the door, the bar is empty, there is not even a leaflet, no matter how you look at it, it is really as the management said, the store has been "stolen" with nothing left.

In addition to the store sign is still there.

It was a very small wooden plank, hanging from the lintel, with an English script written on it.

Lin Chen frowned, and then subconsciously looked at Xing Conglian.

"In French, it means knowledge."

The outstanding language skills of the captain of the criminal police once again made a meritorious contribution.

Lin Chen lowered his eyebrows and pondered, and unexpectedly felt someone behind him smile lightly, he turned his head, only to see Su Fengzi look at Xing Conglian and then look at him, his amber eyes were full of teasing.

"Why are you still here?"

Lin Chen asked angrily.

"Hey, the police are handling the case, aren't the crowd allowed to watch?"

Lin Chen felt that he couldn't communicate with him at all.

At the door of the café called "Knowledge", the torturer turned on a flashlight and shone it into the shop, revealing ridiculous iron nails on the wall where the picture frames used to be hung, and only a few chains were left from the chandelier hanging from the ceiling, and the bulbs and lampshades were gone.

"I've never seen such a thief in my life." The convict Lian sneered and said, "If I find someone from the forensic department, do you think you can't even find a fingerprint on the wall?" ”

"yes, it's so clean." Lin Chen returned to him and looked at the glass door that didn't even have a fingerprint.

"What the hell is in this store, you have to go all out and clean up all the clues that may be left, and leave us no chance at all?" The convict complained nonchalantly, and then saw him crouch down, put on gloves, and briefly checked the door lock.

The lock cylinder does seem to have been violently disassembled, which shows that the other party is very meticulous and thoughtful even if he is acting.

"Actually, you can probably guess that it is nothing more than a record of people entering and leaving, some leaflets, and even this store may be responsible for releasing tasks......" Lin Chen leaned against the wall of the opposite shop, watched the criminal conglian investigate the scene, and said, "It would be nice if there were surveillance records." ”

"Yes." He looked up and pointed to a black teardrop-shaped camera in the southeast corner of the store, "We just can't see it." ”

"What do you think is the chances that the camera is still working and then they've found out we've found the store?" Lin Chen asked.

"The probability of operation is 100 percent." The convict Lian looked at the red dot on the camera, "However, luckily, we are now monitoring the blind spot, and if we don't enter the door, they won't be able to find us." ”

Despite that, he became cautious when he stood up.

After checking the door locks, the company began to inspect the exterior wall of the shop, his rubber-gloved hand brushing the wall, and then stopped at an iron hook.

He turned on the flashlight again, making the pale white wall clearer.

Under the strong light, you can clearly see that there is an area on the white wall that is lighter in color than other places, like a trace of something that has been hung for a long time.

"What did you just say?"

"Which one do you ask?"

"What can you guess?"

"This shop?" Lin Chen looked at the light-colored area, thought for a while, and said: "First of all, its purpose is of course to attract those potential targets to take the bait, there must be a single type of promotion in the store, it may also assume the role of publishing tasks, I mean if it has a wide range of business, there must be a window to the inside and outside......"

"Like a billboard?" Xing Conglian's fingers traced the outline of the light-colored area, which happened to be the size of a typical children's blackboard, "What thief would steal even the propaganda board at the door?" ”

"It's ......"

Lin Chen didn't know how to describe his feelings.

At the moment when he was stunned, Xing Conglian had already turned around and pushed open the jewelry store opposite the coffee bar.

It's closing time, and the female owner of the jewelry store is closing the window and preparing to close the stall.

The convict showed his badge and began to ask for details about the shop opposite.

"The shop opposite, it seems to have closed three days ago, and no one has been here since......" The female boss flicked her sideburns, then lowered her voice, approached the torture and said, "I suspect that it can't be opened, so I deliberately escaped." ”

"Oh?"

"Who has nothing to do to drink coffee underground, the business is so bad, sometimes there is no one for a day, and their clerks are weird, so high!"

"Qinggao?"

"Yes, I think it's the right door, everyone knows each other, I opened for the first time, I went to them to order coffee, it stands to reason that you don't give me a discount, the attitude is better, their waiters ignore me, I sit for a while and leave, never go again......"

The female boss has been resentful of the neighbor on the other side for a long time, and she began to chatter.

The difference in attitude is completely understandable, after all, the female boss is definitely not the target that the organization wants to recruit, Lin Chen decisively interrupted the other party's complaints, and asked: "The property said that they still sell books in the store, do you remember, what type of books are there?" ”

"How do I remember, I've only been there once."

"Since you've been sitting for a while and leaving, there must be something there that makes you feel uncomfortable, maybe it's not just the attitude of the clerk, maybe there's something else?" Lin Chen is kind and seductive.

"When you say that, it's those books ......" The female boss narrowed her eyes and fell into the memory, "Anyway, it's embarrassing to watch, what kind of chicken soup for the soul is, not even a normal magazine!" ”

"Chicken soup for the soul?"

"Oh, it's the kind of 'change yourself in ten days', what kind of 'beautiful and inspirational life' or something."

Lin Chen nodded, pointed to the outer wall of the coffee bar and asked, "Was there anything hanging there?" ”

"There's a little blackboard hanging there, and I have it at the door."

Hearing this, Lin Chen glanced at the torture conglian.

The captain of the criminal police took out the transcript, wrote a few words, and asked: "Perhaps, do you remember what was written on that blackboard?" ”

"Mr. Officer, I really can't remember this, who cares what they wrote!"

Lin Chen felt that Xing Conglian glanced at him with an inquiring eye, although Xing Conglian didn't speak, Lin Chen could roughly guess that he was asking, "Can this memory be awakened?"

Lin Chen shook his head.

The torturer knocked on the notebook and asked: "Then probably, what will be written on it, you can say whatever you think, don't be too specific." ”

"Probably, it's not all today's specials, students are limited to free, takeaway calls and other ......"

"Can I understand that this is a price list that is subject to change?"

"Of course it will change, but it's weird......"

"How?"

"It's not strange, someone always looks at the blackboard at the door...... I don't go into the store, just look at the blackboard......"

"What kind of person is it?"

"What else can it be, aren't all students coming and going here?"

Lin Chen looked back at the iron hooks and gray and white outlines on the opposite wall.

A blackboard, students standing up, and a redunded D-Zone surveillance ......

What was written on the blackboard was perhaps more rigorous than they had guessed.

He could almost imagine every morning the clerk put on his uniform, casually looked at his phone, then slowly tied his apron, pushed open the door, picked up the chalk on the blackboard, and wrote "Today's Special" or something else.

In the eyes of ordinary people, those characters may be the slogans that determine whether or not they go in for a cup of coffee, but in the eyes of others, it may be the difference between life and death for some people.

Students don't even have to walk through the door, and they can see what they're going to do by just passing by the door once in a while.

This approach is so leisurely, so light-hearted, but cold-blooded that it makes people tremble.

Lin Chen took a deep breath, only hoping that this qiē was caused by his too rich imagination.

As if thinking of something, he put down his pen and said to him, "You won't be the same as I guessed, will you?" ”

"What do you think?"

As soon as Lin Chen asked, he was dragged to the corner by the torturer.

"It's an exaggeration, but now that we have a codebook, if they're so bold as to put the instructions on the blackboard, won't we know what the organization is doing with the students?"

Lin Chen was surprised by the train of thought of the criminal slave.

Discrete Mathematics is a codebook of speculation, and the organization that transmits various commands to students in encrypted form is also speculation, and the only way to prove these speculations is to find an exact instruction that is stored in zài, which is what they are missing now.

Maybe someone will occasionally take a picture of the door of this coffee shop?

Maybe someone remembers what was written on that blackboard?

But that was tantamount to looking for a needle in a haystack, and they were still one step too late after all.

"If only there was a camera in the store that monitored the blackboard 24 hours a day." Lin Chen said almost helplessly.

"There's one in this store." Xing Conglian is probably really a man who has a deep tacit understanding with the camera, and he casually pointed out the very inconspicuous camera in the corner of the store: "Open the store now, how can you do it without installing a camera." ”

As he spoke, he walked directly under the camera, and then looked around to see that there were large and small glass mirrors hanging everywhere in the jewelry store, and even the back of the window was mirrored, so it looked full of brightness.

Suddenly, Lin Chen saw Xing Conglian's gaze pause, and Lin Chen followed his gaze and found that Xing Conglian's gaze fell on a floor-to-ceiling mirror.

"Go open the door."

Xing Conglian's voice suddenly became very calm, and Lin Chen opened the door as he said.

The captain of the criminal police picked the corners of his mouth and said, "You say, there are so many mirrors here, how likely is it that one of them will occasionally shine on the small blackboard opposite?" ”
