Through the thick fog, you can see a boat on the sea, Shi Wu flew the aircraft around the ship, and found that there was no one on the boat, so he landed directly on the boat.

The two of them walked out of the aircraft and came to the deck, the damp smell of the sea breeze hit their faces, Yin Bing took a deep breath and felt very comfortable. When I saw the sea around me, I felt so close to it for some reason, as if it was my mother's embrace, and I wanted to throw myself into her arms. As soon as he looked up and saw that Shi Wu had already walked to the cab, he trotted to follow.

"Hey, Xiao Wu, what kind of sonar is we looking for, why is there no one here, where have all the people gone? Why can we tell that something happened to the underwater pyramid through the spirit pupil of such a ghost ship?"

Shi Wu said to Yin Bing with some confusion: "Great God Xingze, can you ask them one by one, I can't remember so many questions at once!"

Yin Bing had to ask the first question first, "What is the sonar device for?"

Shi Wu replied: "It is a kind of sound navigation and ranging, and sonar is an electronic device that uses underwater sound waves to detect, locate and communicate underwater targets. To put it simply, sonar is an acoustic detection device. ”

Yin Bing nodded, indicating that he understood, he didn't ask the second question immediately, but touched his chin and thought for a while, and then he concluded: "The people on this ship originally planned to look for a certain shipwreck or go to that underwater pyramid, and they used sonars to find and detect targets, right?"

Shi Wu immediately stretched out his thumb to express his agreement with Yin Bing's opinion.

"But there is something wrong, if they are going to salvage treasure or explore the pyramids under the sea, why should they leave someone on the ship to guard the ship! Otherwise, even if they have caught the treasure, when they return to the ship, they find that the ship is occupied by someone else, and then it will not be a wedding dress for someone else?"

Shi Wu replied, "I'm afraid that the crew of the ship is already dead." After they got into the water, they moved their sonar and adjusted the sound band, and the sound stimulated their brains and spirits, and they all went to the water and drowned. ”

Yin Bing thought for a moment and asked, "The ghost ships that were found before were caused by this reason, and the people on the ship are gone?"

Shi Wu nodded.

Yin Bing raised his chin at this time and said, "Okay, don't ask the last question, I've almost guessed the answer." It must have been the people who were working on the underwater pyramid who were afraid of being discovered, and they found that someone was using sonar to detect them, and they had already discovered the ship. Then they used some technical means to adjust the frequency of the sonar, and the crew jumped into the sea to commit suicide.

The first thing we had to do was turn off the sonar, which was designed to prevent it from reaching passing ships or passengers on airplanes. So let's find that thing!"

Yin Bing followed behind Shi Wu, analyzing the ins and outs of this matter clearly, and he couldn't help but be proud of his IQ.

"Found it, here!" Shi Wuhan's voice rang out.

Yin Bing was slightly taken aback, he didn't expect Shi Wu to find this scourge so quickly, Shi Wu rushed over and turned off the switch with his hands and feet, and for the sake of insurance, he also directly installed this machine in his own carry-on space. Then he took out the detector and tested it again to see if there were any other sonars on the ship, and when he got the result, he continued to search.

Seeing all this, Yin Bing was a little ashamed, he relied on his own brain to self-righteously show off his reasoning ability here, but he didn't know that Shi Wu was carrying out the task in a down-to-earth manner. If he and Shi Wu were employees of the same company, the company would definitely need an honest employee like Shi Wu who is down-to-earth and willing to work, rather than a smart employee like him who only knows how to talk about it.

Yin Bing closed his mouth and silently began to look for another sonar, and soon he found one in a passenger cabin. Yin Bing turned off the switch, took it to the deck, and joined Shi Wu. Shi Wu also found another one, and then he tested that there was no such suicidal sound wave at all, and then threw the two sonars together in his personal space.

The two of them entered the aircraft again, and the aircraft burrowed directly into the sea and traveled towards the bottom of the sea.

The further you dived, the darker it became, and it was pitch black all around, and occasionally there were small fish with scales on their bodies that could bring a little starlight to the dark seabed, but this light was not enough for Yin Bing and Shi Wu to see the surrounding roads clearly.

In order to prevent being discovered by the probe, Shi Wu turned off the electronic equipment, and the two of them seemed to become a big fish floating in the sea, driven by the current to wander aimlessly on the bottom of the sea.

Yin Bing finally knew why Ling Tong specifically asked him and Shi Wu to scout this matter, this matter didn't require much combat power, but it definitely needed some patience and luck. Thinking of luck, Yin Bing suddenly remembered the fat man, and he felt that the fat man seemed to be more suitable for this task.

The two of them floated on the bottom of the sea for two days and one night, and Yin Bing began to worry that if he couldn't find it again, he would miss Zou Jiajia's return to Cannes from his hometown. If you don't pick her up, you'll probably die an ugly death!

When Yin Bing was drowsy in the water, Shi Wu suddenly pushed Yin Bing with his elbow. Yin Bing suddenly became energetic, he looked out the window, a pyramid about 200 meters high, and the bottom edge of the tower had to be 300 meters long, which looked more spectacular than the pyramids of ancient Egypt.

Even more conspicuous are the two giant holes in the tower, and the sea water is flowing through the giant holes at an alarming speed, forming a huge vortex. And at this moment, Yin Bing and the mighty flying machine were being swept into the vortex little by little.

Yin Bing shouted: "Xiao Wu, hurry up and turn on the engine, escape from here, we are going to be swept in!"

Shi Wu said unusually calmly: "Our task is to observe this pyramid, we just want to enter from the vortex and see what mysteries are inside?"

Yin Bing really took it this time, Shi Wu is indeed a completely desperate character for the sake of the target task, who doesn't like such an employee. Yin Bing didn't struggle anymore, he took out his mobile phone, fastened his seat belt, and prepared for recording.

Shi Wu took out several cameras and fixed them around the aircraft. The aircraft itself originally had the function of detection and recording, but it had to be turned off for fear of being discovered by others about the electronic signal of the flight.

Soon the aircraft was swept into the vortex, and Yin Bing felt that he had been thrown into a drum washing machine, and he opened it quickly, let alone recording it with his mobile phone, and it was already very remarkable that he kept the contents of his stomach from being thrown out.

At this time, he had to thank Lingtong for his special training, in the death coaster, mine rescue and other levels, he had already practiced the ability to maintain his balance and stability as much as possible in high-speed movements. If it weren't for that, he was afraid that he would have been shaken up at this moment, and he would have woken up a long time ago, but this high-speed rotating vortex still exceeded the strength of any level in the special training, and Yin Bing's mobile phone had already flown away at this time.
