Prodigal son never prodigal

Chapter 201 Slot machine eating tiger
Take it back and search and ponder it yourself, there is still a difference.

The operators sitting in the technical center could only see with their eyesight, but Gai Qingyun was extremely familiar with this area.

On the first day of the new year, I rushed to the National Shooting Center to start training. Including going to Qionghai for nearly half a month, Yan Qing has been here for two months.

It was actually two months of very hard training.

Not to mention in Qionghai, the entire shooting center is in the gym every day, and then travels to and from the indoor shooting range, UFO shooting range, restaurant and other places.

I am extremely familiar with the facilities of the entire shooting center. I know every corner and flower bed in my heart.

Therefore, all the surveillance cameras in Yan Qing and Gai Qingyun's minds are different from those of the operators. They have accurate locations and can form a directional relationship in their minds.

Gai Qingyun, who has been watching for seven or eight hours in a row, is still not tired.

He controls a bunch of facial recognition software to help him accurately screen out Director Yan. All Director Yan's movement trajectories for three months are listed and can be compared repeatedly.

Dozens of people cannot achieve his level of efficiency and precision.

People are prone to omissions, laziness and errors in information transmission.

Electronic equipment does not.

In the video listed by Gai Qingyun, the 58-year-old Director Yan is close to retirement age. Every day, he goes from the residential area to the office, eats in the canteen, takes a lunch break, then goes from home to the office, and goes for a swim in the constant-temperature swimming pool before dinner. , and then go home.

Every day started over and over again, with almost no social interaction. The occasional official dinner was held at the restaurant in the shooting center. Well, it was the high-end restaurant inside where Lao Yan showed off to Yan Qing.

Therefore, Director Yan almost never goes out.

Even after the Qionghai incident, nothing has changed.

So the technical hall, which repeatedly screened the videos, naturally ignored this part and focused on various interactions that Director Yan might have had with Lao Yan and others.

But in fact, the entire management center is so big. No matter how experienced you are, you have to come into contact with many people every day. You can imagine the difficulty of screening.

What's more, there are no surveillance cameras in the office, so what can we find?
Gai Qingyun discovered two doubts from this repeated process of going to work.

Without saying a word, Yan Qing went back to the dormitory after leaving the two girls behind. He put on his glasses to watch the scene. Not to mention, it was quite comfortable to handle the case while leaning on the sofa.

"First of all, when you see him coming out of his home, he will definitely walk through the corridor of the Veteran Cadre Activity Center, but there are no cameras in the corridor."

"It makes sense. It's very cold in winter, and sometimes it rains and snows. I see many people passing through here. There is heating, and there are curtains to keep the heat in and out. Some elderly people fell outside and were taken to the hospital..."

As a large gold medal unit that has won honors for more than 30 years, the shooting center has naturally guaranteed the lives of a large number of veteran athletes and cadres through years of accumulation. This is understandable.

But Gai Qingyun was able to come up with data for comparison: "Before you went to Qionghai, it took him 48 seconds to go to work. But since you went to Qionghai, to be precise, he started to increase his efforts to check golf resorts. Boss Huang Before he died, it became 85 seconds, and the time would almost double every time, three times a day..."

The time is displayed in the upper corner of the video, and the time calculation of different camera relays is very clear.

The operators in the hall also saw the speed increased by two or three times, and they might have ignored this difference, but the mobile phone person did not. No matter how many times the speed was, it was a cold difference to him.

This made Yan Qing interested: "Really, if there is a problem, there will be a problem. He goes to work in the morning and noon, and in the evening he goes home first and then swims and eats, three times?"

Gai Qingyun has already taken out the second comparison video: "The constant-temperature swimming pool is in the veteran cadre activity center. In front of the activity center are the archery range and the flying saucer shooting range. Behind it is the indoor shooting range, and then the office building. Almost all departments will There won't be people chatting with him every time he passes by. Going to work in the morning and noon has added time, but there is no change after work and swimming. The key is..."

What appeared on the screen was a picture of Director Yan just coming out of his home, carrying a briefcase, and one, two, three countless still pictures of the same camera, the same angle, and almost the same time.

Flashing quickly...

Only in this way will people notice something.

Yan Qing squinted her eyes: "That bag... seems to have become fatter?"

That's right, it's a very ordinary black briefcase, with accordion-like pleats underneath that widen a bit as things are loaded.

It's not that much wider, and it's absolutely unnoticeable.

But if you accurately connect the photos at the same location, it will look like a cartoon. The whole body is wearing the same dynamic, but the bag seems to move suddenly. The beauty filter in the short video fails, which makes people involuntarily pay attention. arrive.

Gai Qingyun: "You still changed after you went to Qionghai, and then you changed back again when you walked out of the activity center."

Even if it is placed in the bag itself, the difference in change is only two or three finger widths, which can be distinguished by ruthless electronic eyes.

But this is precisely the detail that current facial recognition technology does not care about. No one asks these cameras that can accurately distinguish the width of pupils to identify the width of a bag.

In fact, Gai Qingyun's recognition software is far less accurate than these advanced programs, but he himself is a super artificial intelligence that is higher than software.

The human brain is so smart.

The screenshots taken later when he walked out of the activity center and walked into the office were exactly the same. Even the bag was a bit deflated than before Yan Qing came back.

In other words, Director Yan deliberately emptied his bag, packed his belongings into the activity center, took them out and hid them, and then went to the office again.

Three trips a day, even swimming with a briefcase, for 42 days!
Less than half a month later, Yan Qing and He Shunzhi went to arrest him.

The briefcase had long since returned to its original size, but the delay in the activity center remained the same.I will still go there in the morning, noon and evening, and I will still be delayed for a while.

Of course, there is swimming time inside at night, and there is no way to tell the difference in a few minutes.

Now the two brothers are extremely sure that Director Yan hid something in the Veteran Cadre Activity Center, and that it was sent there by ants moving.

In fact, the answer is very clear.

Maybe the operators in the entire technical center are not very clear about the characteristics of the veteran cadre activity center.

They would not be able to establish a complete structure of the relationship between all the surveillance cameras in the shooting center.

Because there is a heated swimming pool and a gym here, bathing and changing clothes are very common needs.

So a very complete dressing room was built!

What's more, no matter whether it is indoor or outdoor shooting and archery ranges, there is a need to change the competition uniforms. Especially for rifle shooting, there are shooting uniforms, and archers also have a complete set of equipment with shoulder quivers.

This swimming pool locker room, which happens to be in the center of various training and competition facilities, has become a place for all training staff to change clothes.

You must know that those leather shooting uniforms are very heavy and very stuffy to wear. They almost only have underwear inside, and there are separate men's and women's locker rooms.

Anyway, I don’t know if this was considered when building this place.

The entire sports, office, and living facilities area is transferred through this veteran cadre activity center.

Restaurants, canteens, and supermarkets are also in this building, and everyone is very used to it.

So after several renovations, the locker room has become very comprehensive, with a laundry room and a dryer. Many people simply wash and dry their clothes and hang them in the cabinet over there.

It means that every athlete has a customary personal locker, and of course many retired athletes also store their belongings in it.

Including the archery team’s belongings, they don’t have to move them around every day.

If it weren't for the strict management of firearms, everyone might want to lock their guns inside, but it is true that some athletes will secretly put extra and remaining bullets there.

And in this locker room, there happens to be no camera surveillance, and it is a blind spot along with the aisle with nothing to see.

There was no need to hesitate at all. The two brothers packed up their things and went downstairs.

It's past eleven o'clock at night, and the apartment adopts the simplest access management method. When you go out, you hand in your name tag and hang it on the administrator's wall. It's clear who hasn't come back at night.

Of course, given that you all walked out of the gym, there are cameras around the apartment building, and if you are alarmed, you will be expelled directly.

The shooting center is definitely run more strictly than the football program.

Therefore, I don’t need to manage much when I go in and out, as long as I can come back in a short time.

It’s normal to buy something at the 24-hour supermarket.

The two deliberately wandered around the supermarket, then walked into the adjacent aisle and entered the locker room. On the other end, they could go to the swimming pool and gym, which they were very familiar with.

The space is very large, with two to three hundred metal floor-to-ceiling lockers neatly arranged, and not very bright lights. It is actually a bit desolate and eerie in the middle of the night when there is no one around.

It felt like there was enough space in each locker for someone to stand sideways in it.

Gai Qingyun was still playing the ethereal ghost movie soundtrack there, but unfortunately Brother Langzi was not affected by this kind of psychological suggestion at all.

Move around quickly.

Civilian cadres generally do not have fixed lockers, and some only come for swimming and fitness, and only use temporary cubicles the size of express lockers to store mobile phones and keys.

But at least the leaders will not mix with the athletes, and everyone has agreed-upon divisions.

Officials are in quieter corners.

The key is to have Gai Qingyun. He usually has comprehensive records of the past week. After searching, he accidentally saw the scene of Director Yan and Yan Qing's own memory impressions.

I probably chose a direction and gently raised my hand to push it there.

Something that can be transported hundreds of times must have some weight.

Sure enough, there was a cabinet right in the corner. It was very heavy to hold, as if there were fixing screws on the back.

Yan Qing took out a small flashlight with strong light, put it in the slit gap of the side door to illuminate it, then took off his glasses and put them on the top of the cabinet.

That's the only thing with a few vents on it.

Gai Qingyun directly played the loudspeaker from outside: "Bingo!!"

This is the sound the slot machine makes when you win, and you really win.
