That's right! Dispose of corpses! Zhou Lingwu was impressed by his own inspiration, and he was still at a loss just now, but it didn't take long for a flash of inspiration to appear. Pen & Fun & Pavilion www.biquge.info

There are many reasons why Li Junqiu stayed up late, but the only thing that can push Li Junqiu to the word "murderer" is the possibility of disposing of the corpse, and the possibility of this possibility is still very high.

"All we can do now is wait for the progress of the people on both sides of them." Zhou Lingwu said.

Everyone nodded when they heard this, and the old Xuanwu, who originally seemed to be indisputable, also wanted to take a peek to see if Li Junqiu was the "murderer" Zhou Lingwu said.

"Director Xiao, our salvage equipment has been shipped, when do you think it will be launched?" A middle-aged man in an khaki work uniform said.

Director Xiao looked at a small sonar device that was only three meters high and three meters wide consigned by a large box truck, and he couldn't help but feel a pain in his heart. If it weren't for Director Chu's big face, he Director Xiao would be reluctant to spend so much money to invite a sonar instrument to find the corpse! Isn't that overkill! God willing, I must find the corpse, otherwise my money will be spent in vain!

Director Xiao prayed in his heart, although he knew that it was wrong to do this, but compared to the missing or dead Deputy Director Wang Mei, he Director Xiao cared more about the "white flowers" that were spent, it was the funds that he had worked hard to apply for from his superiors, this mission was completely Director Chu's own private task, and the temperament of the case was not as serious as a serial murder case, even if the case was finally solved, and the murderer was caught Li Junqiu, his superiors would not reimburse Director Xiao for the money for the sonar instrument!

"Medium, let's get into the water!" Director Xiao said with a painful face.

After the staff received the order, they immediately used a crane to carefully transfer the sonar instrument weighing a thousand pounds to the lake. Due to the high-tech product of sending sonar instruments, his charging system is not based on the number of attendance, but according to the number of search points, in other words, the lake water of the entire fishing ground is divided into a total of eleven large blocks, each large block has four small positions in different directions, that is to say, there are a total of 44 sites waiting to be measured, and if Director Xiao really points back, then all 44 sites will be searched once. That amount of money is almost catching up with the insurance compensation that Li Junqiu received.

This is why he, Director Xiao, prayed in his heart that the body must be found as soon as possible.

Drip drip drip drip.

After the sonar detector is launched, a red and yellow image appears on the computer connected to the detector through radio waves, the principle of the sonar detector is very simple, it is invented according to the physiological characteristics of animals, and marine mammals such as dolphins and whales have "underwater sonar", they can produce a very certain signal to find food and communicate with each other. Dolphin sonar is highly sensitive, detecting up to 0.2 meters in diameter from a few meters away

m wire and lmm diameter nylon rope can distinguish two signals that are only 200 bs apart, can find fish hundreds of meters away, can cover their eyes in the pool full of bamboo poles to move flexibly and quickly without touching the bamboo poles; Dolphin sonar has a strong ability of "target recognition", which can not only identify different fish, distinguish different materials such as brass, aluminum, bakelite, plastic, etc., but also distinguish the echo of its own voice and the sound wave that people record and play back its voice; The anti-interference ability of dolphin sonar is also amazing, if there is noise interference, it will increase the intensity of the call to override the noise so that its own judgment is not affected; Moreover, dolphin sonar also has the ability to express feelings, and it has been confirmed that dolphins are animals with "language", and it is through their sonar system that they "talk". In particular, the most precious of the four species of freshwater dolphins that survive in the world - the white-sided dolphin in the middle and lower reaches of the Yangtze River in China, its sonar system has a clear "division of labor", some for positioning, some for communication, some for alarm, and has the special function of modulating the phase through frequency modulation

In fact, to put it bluntly, a sonar detector is an underwater camera, which can present underwater images that are difficult to shoot with the naked eye and camera equipment through the principle of sonar.

After about 30 minutes of searching, the investigation of this large site was over, and Director Xiao waited with anticipation for the staff of the sonar detector to inform him of the situation, but what disappointed him was that the results were not optimistic, and a lot of things were found, but none of them were related to the "Wang Mei disappearance case", and all the items found were some old items that were some years old.

After about ten hours of work, the sonar team finally found some clues at the penultimate site, but due to the long hours the sonar equipment had been working in the water and the weather was too cold, the image displayed on the monitor was not clear, and only two objects that vaguely looked like the shape of a human torso could be seen on the monitor.

In the end, in desperation, the sonar team had to send professional divers to the designated location for manual salvage. As soon as Director Xiao heard that he had eyebrows, his already desperate heart rekindled hope, on the one hand, he was happy that he could save money; On the other hand, if the victim's body is found, the progress of the case will definitely be accelerated by 50 percent, and then he will be able to send away the "big Buddha" of Director Chu. Director Xiao, who is used to acting on his own one-third of an acre of land, does not want Director Chu to come and go to him all the year round because this case is not solved.

After the underwater crew entered the water, a large splash flew from the falling water. Then it calmed down, under the special equipment, the divers were able to operate in the deep water area of about 150 meters underwater, and the deepest part of the lake in this fishing ground was only 50 meters, and it was easy for professional divers to work in this environment.

Due to the fact that the body had been soaked in water for a long time, the surface of the corpse was so decomposed that it was difficult to distinguish the identity of the corpse. (To be continued.) )
