Animal Detective

Chapter 268 He's practically the king of dogs

After some discussion, we decided to proceed with both lines of research simultaneously.

On the one hand, we will continue to expand the scope of surveillance.

Then, starting from 10 a.m. the day before yesterday, when Fan Lei left, we screened several key road intersections.

To the west of Shitang Mountain is Lihu Lake, and to the south is also Lihu Lake. If Fan Lei wants to leave, he can only go north, east, or southeast.

Screening was conducted on all vehicles in three directions, at all key road nodes, and within the corresponding time periods.

Just check the taxis.

We won't investigate the ride-hailing service for now, because Fan Lei has never registered an account with a ride-hailing platform.

The phone numbers are all registered under real names.

Even if Fan Lei managed to buy a phone number, he could only check taxis first and then ride-hailing services.

Filter out the taxis within the specified time period, and then contact the drivers to confirm whether they had taken Fan Lei.

This requires a huge investment of human resources.

However, special cases with a time limit for solving them require a significant investment of manpower.

In Kong Lingzhi's words, the goal is to spread a net wide, sparing no expense, and absolutely not let Fan Lei escape.

On the other hand, there are speculations about Liu Baoqing.

Drones were launched to search the mountainous area.

In the past two years, drones have begun to be used by the police, and thermal imaging modules can also be installed.

It's late March now, and the daytime temperature in Nanjiang is just over ten degrees Celsius, while the nighttime temperature is even lower, so the thermal imaging results should be quite good.

The municipal bureau has these devices.

Shen Xin was getting annoyed watching the surveillance footage, so he decided to follow the city bureau staff to watch them release the drones.

Just place it in the spot in Fan Lei's dormitory.

Two technicians from the Municipal Bureau arrived, one named Wang Qing and the other Mao Jiqiang.

They were all very young, in their early twenties.

The two of them unloaded a rather large box from the car.

Drones have developed rapidly in recent years, especially civilian commercial drones.

Shen Xin had seen his friends fly drones before, but he was too busy with work to bother with it himself.

But the drone in front of us was clearly not a civilian product; it had eight arms and was quite large.

After asking Wang Qingcai, I learned that the municipal bureau had purchased several units at the end of last year and trained a few of them on how to use them.

They also said they would form a dedicated drone policing team in the future.

"Why didn't you buy it sooner?"

Shen Xin recalled the time last year when he led police dogs to search for Wang Yuansheng in Dingshan.

I was in a terrible state at the time.

If we had this thing, life would be so much easier.

Wang Qing shrugged and said in a low voice that it might be expensive. He explained that the industrial-grade drone in front of him, called the T600, with all its working modules, cost 40 yuan per unit.

"So expensive?"

Shen Xin was taken aback, thinking to himself, "That's it, isn't it?"

Wang Qing didn't explain, and worked with Mao Jiqiang to adjust the parameters.

This device is equipped with a 30x optical zoom lens and a thermal imaging module, with a temperature measurement accuracy of ±2 degrees Celsius, and can identify human heat sources from 500 meters away.

With 30x optical zoom, it can also identify targets at a maximum distance of 1000 meters.

It is specifically designed for counter-terrorism reconnaissance.

"sharp."

Shen Xin gave a thumbs up.

Aside from being expensive, it seems to have no problems at all, and it's even better than a police dog.

The drone started up with a lot of noise, took off, and flew towards Shitang Mountain.

The image is transmitted in real time, and it is clearly visible through the thermal imaging lens.

For example, if a rabbit runs by, it will be highlighted on the screen.

Mao Jiqiang operated the drone, while Wang Qing identified it, then said that the only problem was that it required manual identification.

They also mentioned that software for automatic recognition is currently being developed, like the AI ​​artificial intelligence in science fiction movies, and if such software exists, things will only become easier.

Shen Xin nodded to himself.

I'm increasingly convinced that Geng Ke and the others are right; the cost of committing crimes is far too high these days.

The drone swept along the ridgeline.

Discoveries are made from time to time.

There are still animals on the mountain, and quite a few of them.

They also spotted people along the way.

Upon closer inspection, it turned out to be a hiking and off-road enthusiast.

Flying from east to west and back, it took almost half an hour because we still needed to identify the objects.

Then it flew back from the other side, which took another half hour.

And then... the power went out.

The battery needs to be replaced.

After flying back and forth for a while, Shen Xin suddenly felt that this thing wasn't so beautiful after all.

First, let's look at the parameters.

Let's not even mention its one-hour battery life.

Wang Qing previously said that with 30x optical zoom, you can see things a kilometer away.

It also has a thermal imaging module that can detect temperature changes up to 500 meters away.

But Shen Xin felt that this should be the theoretical maximum data.

If you take a telescope, you can see things a kilometer away.

In reality, it's not like that at all when you're actually working.

For example, this scope of work.

Shen Xin thought it was flying high in the sky, looking at it from hundreds of meters away.

But not.

Because of the distance, the area is larger, but the details of the ground are not clear.

Its thermal imaging has a resolution of only 320*240. Even when it flies at an altitude of hundreds of meters, it can only identify heat sources at the meter level.

In addition, due to the obstruction of leaves, the drone did not fly very high, about 50 meters above the treetops, in order to make the thermal imaging module effective enough.

In Wang Qing's words, using a wide-angle lens can cover a width of more than fifty meters.

50 meters sounds like a lot, but there's a mountain in front of us.

Guangshitang Mountain, running north-south, is almost 2 kilometers long.

That means you have to scan back and forth 40 times.

A flight takes half an hour, but to cover Shitang Mountain alone would take 20 hours, almost a whole day.

There is another crucial issue.

That means people move around. If you scan the area in order, and you happen to pass by Fan Lei while he runs to the area you scanned, then you'll miss him.

This efficiency seems a bit low.

And it's not just Shitang Mountain; further south, there are Langxue, Zhangjun, and several other mountains, stretching seven or eight kilometers from north to south.

How long will it take to find this?
Shen Xin raised his doubts, and Wang Qing obviously understood as well, saying, "There's nothing we can do about it. The main problem is that we're short of pilots. You need someone to watch and identify them, otherwise we could bring a couple more over to search together."

Shen Xin shook his head inwardly; this efficiency was too low.

And it's not even certain that Fan Lei is hiding on the mountain.

But upon closer examination, Liu Baoqing's speculation makes sense.

After killing Xu Ruilin, he thought of crossing the mountain to return to his dormitory.

Although he was imprisoned for ten years, he was released in 14 years. He must be well aware of how fast society is developing.

This guy is honest, but he's not stupid.

He was ruthless, and Zhang Hancheng thought he was a master, which is why he considered starting the investigation from He Wei's side.

From Fan Lei's perspective, he probably also knew that escaping from the ubiquitous surveillance cameras was not an easy task.

What should I do?
Hiding in the mountains and waiting for the storm to pass before coming out is also a good option.

He's a seasoned criminal; even criminals know to hide after committing a crime and run away when things calm down.

This area is surrounded by mountains to the north and south, so it's hard to find a place to settle down.

As for food and drink, you can prepare some in advance. As long as you can endure the hardship, it is possible to hide them for a period of time.

Fan Lei can eat instant noodles every day, which shows he can endure hardship.

Shen Xin pondered for a while and then found Cui Xuesong, who was in charge of the site.

He is the deputy captain of the Criminal Investigation Brigade of the New District, and he is here to be in charge of the search in this area.

Shen Xin shared his thoughts.

Cui Xuesong nodded in agreement.

Liu Baoqing's theory that Fan Lei was hiding in the mountain was something he had discussed with him.

"This efficiency is a bit low." Cui Xuesong frowned slightly as he looked at Wang Qing and the other man in the distance.

Organizing a search party would be even less efficient. This area is so large, with mountainous terrain covering at least ten square kilometers; how many people would it take to search it all?

Shen Xin turned his head to look at the tree-covered Shitang Mountain, his mind racing, searching for a solution.

Human search is definitely not feasible; it's too slow.

The last time we searched Dingshan, it was exhausting.

If humans can't do it, then what about dogs?

Shen Xin's heart skipped a beat, and he suddenly remembered the time when he had Tian Kui lead a pack of dogs to run all over the mountain.

"Captain Cui, I have an idea," Shen Xin said hurriedly.

Half an hour later, Liu Baoqing arrived after hearing the news.

Cai Zhe arrived shortly after.

Of course, they also have their own Paw Patrol army.

Tian Kui and the others.

Lian Tianqiao was also brought along; she's currently breastfeeding, and her health has actually recovered.

Including Odin, there's also his wife Frigga.

Then the three of them, Tiger Stripe.

These are a total of 41 dogs.

Cai Zhe carried down a large cardboard box, saying that it was fortunate that Shen Xin had prepared it in advance, otherwise it would have been impossible to find it at the last minute.

It refers to a positioning collar.

When the police dog project started, Shen Xin had considered this and made a batch of collars so that the police dogs wouldn't get lost when they were sent out.

Then Tiankui and the others put on the police dog vests from the police dog base.

Cai Zhe came over and worked with Shen Xin to put collars on all the police dogs and attach cameras and power banks to their vests.

Liu Baoqing and the others watched from the sidelines.

It's rather troublesome. Shen Xin remembered what Cai Zhe had mentioned before, saying that in Songpu, there was a smart helmet for police dogs that had a camera and a wireless transmission module, all integrated together, which was more convenient than this.

Tell him to ask around later.

Having this kind of helmet would make reconnaissance much easier.

After fiddling around for a while, Shen Xin picked up the walkie-talkie, ran a distance away, and tried it out.

"Sit down, everyone!"

From a distance of several dozen meters, Shen Xin gave the order.

Shen Xin's voice came through all the walkie-talkies in the vests.

A few of them were still agitated, looking around for the source of the sound.

However, Shen Xin had already taught them about the function of the walkie-talkie, explaining that their own voice would come out from it.

But the order remained unchanged.

Forty-one dogs sat down in unison.

Tiankui and Huban finally got a chance to get together, and they dawdled before finally sitting down.

Although they were mentally prepared, the scene still startled everyone present.

Cui Xuesong stared in disbelief and said to Liu Baoqing, "Old Liu, this kid is simply a dog king."

Liu Baoqing nodded in deep agreement, secretly alarmed.

Shen Xin's voice rang out again: "Turn around."

Having experienced it once, the dogs had adapted and turned around in unison.

This display left everyone present speechless.

Wang Qing and his companion didn't even bother to launch the drone; they just stared in disbelief.

Shen Xin walked over and said, "Captain Liu, I think it's a good idea."

Liu Baoqing nodded blankly.

Shen Xin came up with a plan: to use these police dogs to search the entire mountainside.

They have positioning collars that can track their location, as well as cameras and drones that can track their discoveries.

As long as you can smell Fan Lei's scent on the mountain, you can immediately pinpoint his location.

With 41 dogs running all over the mountains, the search area and speed were much faster than that of drones.

Shen Xin can issue orders at any time via walkie-talkie.

"If you say yes, then yes."

Liu Baoqing was truly dumbfounded.

I've never seen anything like this before, nor have I ever experienced anything like it.

Shen Xin didn't waste any words; it was already nine o'clock in the morning.

It was Fan Lei's quilt again. Shen Xin communicated with each police dog, making them remember the scent.

He then instructed them to go up the mountain to find the scent, and to act according to his commands.

As for the few that haven't reached the second phase yet, Shen Xin couldn't worry about them.

In any case, most of them are in the second stage and can understand what they mean.

After much effort, we finally figured it out one by one.

Shen Xin clapped his hands to attract the attention of all the dogs.

Then, pointing to Shitang Mountain, he shouted, "Let's go!"

Tian Kui darted away in a flash.

Of course, tiger stripes are also indispensable.

Then dozens of dogs rushed up the mountain in a huge swarm.

This scene sent chills down the spines of everyone present.

Shen Xin moved closer to Cai Zhe's computer.

He numbered all the police dogs' locator collars and then dragged them into the map.

This way, we can locate Tiankui and the others at any time, and also find out which dog isn't working diligently or is slacking off.

Sure enough, after running a short distance, Tiger Stripe and Sky King veered off course from the main group, turned left, and circled around behind the houses.

This is a time to slip away.

Shen Xin immediately picked up the walkie-talkie and shouted, "Tiger Stripes, Tian Kui, what do you want to do? Get back here!"

On the map, they stopped at two points and then reluctantly caught up with the main group.

Cai Zhe immediately gave Shen Xin a thumbs up.

He knew that Tiger Stripe was most afraid of Shen Xin.

Climbing mountains is difficult for humans, but it's much easier for dogs.

Seeing that all the dogs were still huddled together, Shen Xin ordered them to disperse and not follow, and to go find the dogs themselves.

At this moment, even Zhang Hancheng and his men rushed over upon hearing the news.

Seeing the red dots covering the mountains and fields on the map was also quite unbelievable.

"I've never seen anything like it, I've never seen anything done like this before." Du Yong shook his head.

Zhang Hancheng watched intently.

The situation is quite large now, but whether we can find Fan Lei is another matter.

Moreover, it's uncertain whether Fan Lei is even on the mountain.

The dogs were very fast; they scattered and ran all over the place.

Shen Xin would use the walkie-talkie to remind anyone who was running in the wrong direction, based on their number.

Overall, tell them to search southwards.

The south side is all mountains, so I feel like Fan Lei would hide in that direction.

Half an hour later, the one who ran the furthest had already reached a position two kilometers south of the starting point, and had already left the area of ​​Shitang Mountain.

Then more and more dogs ran out of range.

It hasn't been discovered yet.

If the dog notices, it will stop barking.

Another twenty minutes passed, and the furthest distance was already almost three kilometers.

Just then, Cai Zhe suddenly pointed to a spot and said, "Shen Xin, the celestial anomaly has stopped. Have you made a discovery?"

On the map, the red dot representing the strange phenomenon stopped and then moved slowly.

This means he's not running anymore; he may have made a discovery.

Shen Xin quickly looked at Wang Qing.

At the same time, Cai Zhe also remotely activated the camera on Tianyi's body.

The screen appears.

There was a microphone, and you could hear Tianyi calling.

In the shaky footage, about ten meters away, beneath a rock, there is a recessed space.

Then a man stood there, also yelling at Tianyi, and even picked up stones from the ground and threw them at him.

"It's Fan Lei!"

Zhang Hancheng's eyes widened, and he exclaimed in surprise.

They actually found it!
