"Is there a lot of surveillance in this yard?" driving the car, Bai Song's heartbeat had soared to more than 120, but he still pretended to ask casually.

"Nope..."

"There are four, and the locations are all very inconspicuous, but it's okay, I told Huahua, don't say it if you find it. Ji Yue interrupted Wang Huadong's words.

Wang Huadong turned his head and stared at the two dogs, his eyes were huge, and he felt that people were not as good as dogs, and then asked, "It... They... How... How did you find out..."

"Smell it", Ji Yue took it for granted: "The iron itself has no taste, but after the human skin comes into contact with the iron, the iron is oxidized to ferroic ions, and then becomes ferric iron, and finally reduces some of the peroxide value of the human body to 1-octen-3-one, which is very sensitive, and the few positions they find are quite special, it must be a camera." However, fortunately, it is a brick house, and if it is reinforced concrete in the city, it will not smell. ”

For dogs, bustling urban areas and busy traffic are nightmares, and these rural areas are the most suitable for their abilities.

"Have you seen it?" Wang Huadong was still shocked.

"I'll be exposed when I see it", Ji Yue touched the dog: "They are my eyes." ”

"Then what if no one has touched the camera and doesn't have this ketone?" Wang Huadong felt that he had to raise the bar to maintain the dignity of human beings.

"That's okay, when the metallic iron is processed, the purity can't be too pure, there will be carbon and phosphorus in it, and the rain in the south is acidic, plus the wind and sun, some iron tools are slightly corroded, and they will release small molecules of organic phosphorus, as long as the concentration is more than 0.1 nanograms per cubic meter, they can smell. Ji Yue said as a matter of course.

"Ten cubic meters and one nanogram..."Wang Huadong suddenly felt that he had failed to raise the bar, and his life was bleak.

...

Not long ago, because of the hospital's case, Bai Song and Wang Huadong were silent.

...

At this moment, Bai Song felt that his heartbeat was also much calmer, and an emotion that a person was inferior to a dog gradually reached a common frequency with Wang Huadong.

With such a hidden camera installed, Bai Song no longer inked, and immediately called the Qin detachment and reported the situation, there must be something wrong with this place.

Block the door!

Although there is also a high probability of scaring the snake, it is rare to encounter such good luck and cannot be missed!

Although it is only the conclusion of two dogs, since everyone is the first to come here to investigate, they must feel that this place is the most suspicious, so it cannot be completely coincidental, it can only be said that Wang Huadong, Sun Jie, Wang Liang and others are indeed reliable.

Moreover, in the past two days of contact with Ji Yue, Bai Song has a lot of trust in this person, a man who can run so far for a dog is more trustworthy than most people.

Bai Song's call really alarmed too many people.

They parked the two cars a hundred meters away and parked together, and Bai Song told everyone about the situation, quietly waiting for the arrival of the support team.

"Is it really here?" Wang Liang's eyes widened: "What kind of camera, I really want to go and see it." ”

"Won't you know in a while?" Wang Huadong was very impressed by Huahua and Huahua's ability, at this time, he had already turned into a little fan brother, turned around and asked Ji Yue: "Is this dog easy to train?

"It's difficult", Ji Yue said truthfully: "It is more difficult to cultivate it than to train an excellent policeman, of course, they are also a part of the police." ”

"Well, that's for sure. Wang Huadong approached and wanted to touch Huahua, but he still didn't get started, which was a kind of respect for Ji Yue.

This kind of dog with a keen sense of smell, many times, some smells are not a big deal for humans, but they are a disaster for them.

About half an hour later, Bai Song received a call from the general manager of the city bureau, saying that they were already in the vicinity and ready to cooperate with the action at any time.

Where is it?

Bai Song looked around, only to find a few people who looked like policemen, if there was no phone number, so at such a glance, he didn't know that these people were police.

Then, Bai Song received a call from the local police, and a special police squadron had been dispatched, but the first step was the police from the police station.

Everything is ready, the first wave to go in, is the "police station police", of course, it is the police station in disguise, the four people who went in, one police costume, three auxiliary police costumes, are all members of the local criminal police team, body armor and guns are brought, go in to do the first wave of investigation.

It can be seen that the local police attach great importance to the matter raised by Bai Song and others.

This has to be said because the incident of the previous night was too big, and the people here are already too nervous.

48-hour uninterrupted inspections are not a simple matter.

The leaders of the Changhe City Bureau have always attached great importance to it, which is why the Qin detachment and this side asked for help so quickly.

In fact, there is a special agency for the interconnection of provincial-level administrative units, but it is only responsible for matchmaking, and the real docking is generally a department-level cadre at the level of the Qin detachment.

In Tianhua City, a municipality directly under the central government, department-level cadres may not seem so powerful, but in many places, in the public security system, this is already a high-ranking official.

Bai Song is also under a lot of pressure, such a large-scale operation, if nothing is discovered, all the responsibility is also borne by him Captain Bai, and it is impossible to push it to anyone.

But for such a thing as taking responsibility, Captain Bai has never been afraid!

The four criminal policemen knocked on the door, but no one opened the compound, so the four kept knocking.

There are policemen one or two hundred meters away from here, and they are not afraid of the people inside opening the back door and running, so the four policemen are calm and slowly knock on the door.

The courtyard door slowly opened, and the whole compound was covered with a layer of color steel tiles, which was used to shelter from the wind and rain, and it looked a little down, and it was a young man who opened the door, and he handed a cigarette to the four policemen very politely, and asked what was the matter.

"Someone called the police and said that there is contraband in your yard, let's take a look here?" the criminal policeman in police uniform took a cigarette and lit it, "Let's go in and have a look." ”

"Please come in, please come in..." The man smiled and invited the four policemen in: "It's all factories, there's no place to sit, oops, I thought it was something, I guess I don't know who I've offended recently, you know, although our kind of factory is not big, but the benefits are good, and people hate it! How can we have contraband here..."

The man took advantage of the situation and stuffed the good cigarette in his hand into the policeman's pocket, and the policeman casually put it in his pocket.

Seeing this scene, the man was very happy, and immediately motioned for the police to talk to him alone, making it clear that he wanted to give benefits.
