During the process of sending and receiving messages, the radio buttons are used very frequently, and it is often necessary to apply a little engine oil on the connection to make the operation smoother.
As long as it is a machine, it will have the smell of engine oil to some extent. After smelling the radio parts contaminated with engine oil in advance, the police dog can use its olfactory memory to find things with the same smell.
Of course, this is only relative.
People can't smell it.
But a trained police dog can.
Liu Wenlong entered the yard, looked at the bacon hanging in the shade, and said to Qi Yue beside him: "Ten years ago, I went to Changsha once. At noon, I went to a restaurant to eat and ordered a local special dish called wine.
Fragrant bacon, when it came to the table, I saw what kind of wine-flavored bacon it was. It was clearly fried red pepper, green pepper, and then dried pepper. Grandma’s was so spicy that my tongue was swollen!"
Qi Yue smiled and said: "Next time you have a chance, you can try the fish head with chopped pepper."
Liu Wenlong laughed: "Forget it, just listen to the name of the dish!"
The dog handler led the police dog into the side room.
Liu Wenlong and Qi Yue also followed in.
Just like last time, there were more than a dozen pieces of bacon piled on the table. In addition to the bacon, there was a bamboo pole set up in the corner and two rows of cured fish hung staggered.
Under the command of the dog handler, the police dog sniffed around the room.
"Why does it stink?"
Liu Wenlong looked around for the source of the odor.
Qi Yue said: "It seems that the cured fish smells bad."
Boss Wang had been standing at the door. When he heard this sentence, he immediately said: "Officer, you are no longer an amateur. It doesn't stink. This is the smell of cured fish."
Liu Wenlong smiled and said: "It's just like stinky tofu. It smells bad but tastes delicious."
Boss Wang echoed: "Yes, yes, it smells bad but tastes delicious."
Liu Wenlong asked: "Can I eat so much cured fish and bacon?"
"My family owns a restaurant and consumes a lot of food."
Boss Wang explained.
"Which restaurant?"
"The Xiaoxiang Garden at the corner of the street."
Liu Wenlong murmured to himself: "Xiaoxiangyuan, another Hunan dish that is so spicy that it will kill you..."
The police dog suddenly sneezed.
The front paws kept scratching the nose.
Liu Wenlong asked the dog handler: "What's wrong with it?"
"I must have choked..."
The dog handler isn't entirely sure either.
Whole bags of peppercorns and paprika are stacked in the corner.
It’s not surprising that police dogs were choked.
After a while, the police dog gradually calmed down and looked up at the dog handler.
This means the search is over.
Liu Wenlong frowned and walked out quickly.
He didn't want to stay in this room that was full of fishy smell for even a minute.
After everyone else had gone out, Qi Yue squatted down and pretended to tie his shoelaces, and took a close look at the place where the police dog had sniffed - there was a small pile of gray powder there.
If you get close, you will smell a pungent and choking stench. This kind of thing is called stink vine, also known as chicken shit vine. It can be dried and ground into powder and can be used as medicine. This kind of wild plant can be found in many places in the south, among which Yunnan
The ones produced in Nishizo are notoriously smelly.
If a dog accidentally smells it, it will lose its sense of smell within ten minutes.
In the early years, Qi Yue and his classmates traveled to western Yunnan. There were jungles on the west bank of the Nu River. They were worried about getting lost, so they brought hunting dogs to clear the way. On the way, the hunting dogs smelled the smelly vines and almost couldn't find their way home.
The last time he came here, he was also in this wing. Qi Yue smelled the smell of vines and had a vague idea of what was going on.
At the same time, he also knew that the reason why the cured fish and bacon were piled up in the wing was not because there was no place to hang them as Boss Wang said, but to cover up the smell of the vines.
Therefore, the radio station must be hidden in the wing!
"Dogs are more efficient than you!"
Liu Wenlong stood in the yard and scolded the agents carrying metal detectors.
The agent took off the detector on his body and said with a grimace: "Captain, this thing is very heavy. We are checking one house after another. We can't do it quickly even if we want to."
Liu Wenlong sneered: "It's too heavy for four people to carry on a shift. Do you know that engineers use it to detect mines and only one person carries it on his back? If I let you go to the battlefield, you won't immediately become a deserter!"
The agent did not dare to argue anymore.
Silently helping his companions organize the metal detector.
The metal detector weighs almost forty pounds.
It's better to take turns carrying it, but no one can bear the burden of carrying such a heavy machine on a hot day for a long time.
The so-called metal detector is actually a modified portable mine detector used by Japanese soldiers. The effective detection radius can reach 25 centimeters.
The main body of the detector is a metal box 24 cm long, 19 cm high, and 13 cm wide. Components including batteries, vacuum tubes, amplifiers, etc. are placed in the box. The other end is a ring-shaped detection device.
Compared with vehicle-mounted mine detectors weighing hundreds of kilograms.
This kind of thing is already considered "micro".
"Qi Yue, look at them and don't be careless. I'm going to make a phone call."
Liu Wenlong left in a hurry.
Qi Yue was not the only person present.
Even if he wanted to cheat, he couldn't.
Boss Wang and his wife kept smiling and asked the agents who were rummaging around to handle it gently.
In the face of strong power, showing weakness is also a way of self-protection.
Ten minutes later, all the people from the Secret Service Department, including Qi Yue, left.
Police dogs have searched and metal detectors have been checked. According to past practice, no one will come to Boss Wang's house again to cause trouble.
In fact, it was just as Qi Yue guessed.
The radio station is hidden in the wing.
When you pry open the floor tiles under the table, you will find a 30-centimeter-deep hole. The radio is hidden inside. With the current level of technology, the depth of the hole is just beyond the effective radius of the metal detector.
We dare not dig the hole too deep, mainly because we are worried that the spies will use hard objects such as hammers to test the abnormal sound under the floor tiles - the shallower the hole, the more normal the sound will be.
In order to ensure nothing goes wrong, Boss Wang deliberately covered the entrance of the hole with a lead plate - the lead plate can effectively block the metal detector.
"Finally passed the test..."
Boss Wang sighed and said.
His wife's name is Yang Jie, and she is a telegraph operator.
The two pretended to be a couple and used the restaurant as a cover to come to Binjiang for more than half a year.
Yang Jie said: "Those two young girls from the Youth League are still lacking in experience. In my opinion, it is best to let them leave Binjiang temporarily..."
Boss Wang said: "The enemy has not found the radio station, so they will definitely increase surveillance in this area. It would be inappropriate for them to leave Binjiang at this time. Don't worry, I have asked Ah Shui to inform them to stop all activities and treat them as just coming."
There shouldn’t be any problems if you go on a riverside tour.”
Yang Jie thought for a while: "Is it necessary to continue their beauty trap?"
Boss Wang said: "At the beginning, I had no hope that this beauty trap would succeed. I had warned them long ago, but they acted without authorization. Fortunately, they still had room for maneuver..."
