Police Detective

"The diver will go down soon." Team Liu received a call from Bai Song: "The positioning has just been done. It is estimated that the general results will be available in five minutes."

"Well, Team Liu, I have a guess here that I need to tell you." Bai Song said: "I suspect that between the two doors below, there may be a small submarine that is usually stored in the speedboat. Not necessarily all of them."

"Submarine? Impossible," Team Liu said: "There are not all submarines here. They are all registered. If they are not officially registered, they will not be sold by shipyards."

"That's a general situation, you have seen this situation too." Bai Song said.

"Actually, you Qin Detachment also mentioned to me about this diving equipment just now, let me pay attention to it, but there is no result," Liu said: "We also have regular patrols in the river here. If it does, I guess it was discovered long ago."

"If it's been locked between the two doors, then can't you find it?" Although Bai Song was surprised at Qin Detachment's mention of this question, he didn't ask much, and then said: "I also guess that the opponent's this The submarines and speedboats that may exist are the last way to prepare, and it is impossible to wander around in normal times."

"Um..." Team Liu thought for a while: "If you are really sure that it is a submarine, you have to report it to your superiors. This matter is not something we can solve. Maybe you need to borrow one from the unit stationed here. An anti-submarine helicopter is here."

Bai Song was stunned for a few seconds, and the game was getting bigger and bigger!

What the **** is an anti-submarine helicopter!

"Does our Jiangshang Guards have no ship-equipped sonars?" Bai Song asked.

"Yes, but they have to be larger ships. The current small boats around here don't have this thing. It takes an hour or two to transfer a boat from dozens of nautical miles away from the countercurrent," said Liu team. "Don’t worry, if the divers really find there are signs of the submarine going out in a while, the relevant departments will definitely be willing to participate. After all, this kind of thing, if it is small, is a case of our public security, if it is big, it may be regarded as a die. Acted."

...

Bai Song felt that he was dreaming, but at this time he was particularly excited.

Anti-submarine helicopter!

Generally speaking, large rivers like the Yangtze River, as our inland rivers, are rarely infiltrated, but they still have to be guarded. As the main tributary of the Xiangjiang River, it is directly connected to Donghu Lake. This kind of thing must be taken seriously.

Submarines, under the current policy, are not allowed to travel underwater at will. General sightseeing submarines have to approve a special area.

And underwater detection is actually not as difficult as imagined, mainly relying on technology.

Baisong has generally heard of how powerful anti-submarine helicopters are. The installed dipping sonar allows the helicopter to fly to a certain detection point, hover at low altitude, and hoist the transducer array into the water to the best depth. Active or passive omnidirectional search, a performance search within a radius of ten kilometers.

If there is such a big killer, then...hehe...

Is this a dimensionality reduction blow?

Bai Song touched his chin with his hand: "Team Liu, it's up to you."

"You wait a while," Team Liu said: "The diver will have a clue in a while."

Bai Song and Captain Liu continued to chat about other circumstances of the case, and the diver successfully returned to the surface.

According to the diver's description, there is a thick stainless steel door underneath, which is an electro-hydraulic structure, and is a waterproof circuit. It is currently open. Moreover, although the circuit is waterproof, it has now been completely powered off.

In addition, there is also a water inlet inside. After opening, water can quickly enter into it, so that the cabin between the two doors is quickly filled with water, and the pressure is unified inside and outside, which helps hydraulic pressure The opening of the door.

This cabin is about five meters long and wide, and the hydraulic door is very large, which can basically satisfy people entering and exiting here sideways.

Due to the sediment problem at the bottom of the river, this cabin has basically been filled in this short period of time. Of course, no one knows how much sand has been put in. It is difficult to judge the depth here anyway. From the instrument, it is generally possible. The judgment is that the height should be between 5-8 meters.

The silt at the bottom of the river slowly enters this cabin with the current. Basically, it can be said that in another hour, the cabin will be completely filled with silt.

In other words, the escape route here is basically one-off and cannot be used as a stand-by.

"Can it be judged that there is a submarine in this situation?" Bai Song asked.

"I'm afraid not." Team Liu looked bad: "I didn't expect the underwater to be so muddy, and our divers would not be able to find any additional clues. This is too difficult. When it is completely buried here, it is estimated that there will be no way to find clues. .

The door of the underground corridor was basically afraid to open it. In this situation, we can't mobilize people. After all, anti-submarine aircraft is not a joke. Our military and civilian cooperation have only seen it once in so many years. "

Bai Song expressed his understanding, and his excitement just calmed down a little: "Then let's mobilize the sonar boat for a trip."

"Okay, let me first ask the branch if there are fishing boats and salvage boats carrying sonar equipment nearby. At the same time, the boats of the water security team are also moving here." Team Liu said, "Just leave this to us. "

"Well, Team Liu, let me ask again~www.wuxiaspot.com~When will the DNA results on our side be made?"

"The investigators have already taken samples. It is estimated that it will take more than 8 hours." Team Liu said: "This is the fastest speed."

"Okay, I understand." Bai Song nodded. This is already considered very fast. If the laboratory in Tianhua City works overtime, it will basically be at this time.

"Well, we have sent the DNA sequence of the criminal suspect Feng Yiling you provided to the DNA identification center. Don't worry about this. If there is a result, I will tell you the first time." Captain Liu said: "Our branch Director Li of the United States will be there in a while. It is estimated that in half an hour, all the people from the municipal and provincial departments will be there. The white team will come over and take a look?"

"No, we have a forensic doctor there. You can take care of it. You should contact the people in our plainclothes team." Bai Song said, "I'm still looking for the condition of this submarine outside."

"There are no good clues about this, so I can't rush." ​​Team Liu said.

"The clue is indeed..." Bai Song had just said halfway, when he suddenly received a text message on his phone, he was stunned, and then shuddered: "Team Liu, I can be sure that there is a submarine!"
