Lin Yuan continued: "Now it seems that there are two reasons for sinking. One comes from itself, such as the missile being loaded exploded; the other comes from outside, such as hitting a reef, encountering military strikes, etc. I prefer to sink.

The reason comes from oneself, and the most likely reason is that the missile exploded, so the focus of our next work is to salvage the shipwreck, find evidence, and judge whether the missile explosion caused the sinking of the Wanli Jingtao."

Xu Siyuan said: "If you want to salvage the wreck, you must know where it sank. But the sea is so big, how can we know where it sank? But if you want to know where it sank, it is a thing.

Very difficult thing.”

Lin Yuan said: "Yes, this matter is indeed very difficult, but even the most difficult thing is, there is always a solution. Let's take the chart over and analyze where it may sink."

Xu Siyuan then asked someone to open an electronic chart on the big screen. Lin Yuan said: "Let's mark the lost contact first."

At this time, an officer knocked on the computer for a while, and then a red dot appeared on the chart. The officer said: "Ship Lin, this is the location of the last time the Wanli Jingtao reported. Our positioning error is 300 meters.

Now we draw a circle with this point as the center and three hundred meters as the radius. The Wanli Jingtao may be inside this circle."

After the officer finished speaking, he drew a circle on the chart. Lin Yuan continued, "Where is the place where he found Qian Wanghai?"

The officer drew a circle on the chart and said, "It's here." Lin Yuan continued, "What was the wind speed last night and what about the ocean current speed? Let's assume that Qian Wanghai entered the water when the transport ship sank.

Based on these two data, calculate the possible location of Qian Wanghai.”

The officer was stunned for a moment and said, "But there is a sea on the sea. When he floats on the sea, he will definitely be affected by the sea. In other words, his speed will definitely not be the superposition of ocean current speed and wind speed.

Moreover, the speed of the wind is not constant, so there will be great errors in the calculation."

Lin Yuan said: "Don't consider those first, just calculate the water surface as still water."

The officer said, "I understand." So he operated on the computer for a while, and then marked a point on the chart. The officer said, "This is the location where Qian Wanghai enters the water without considering all complex situations."

Lin Yuan said: "Correate the position coordinates of this point, then draw a circle with the center of this point, 20 kilometers, no, 30 kilometers as the radius, and then draw a circle with the same radius at the lost position.

If you take the intersection of these two circles, the Wanli Jingtao should sink into this intersection."

Xu Siyuan said: "Ship Lin, is our next step to search the seabed of this intersection range?"

Lin Yuan said: "There is no other way now, this is all we can do."

Xu Siyuan said: "But Lin Shuai, the area of ​​this intersection is nearly 1,000 square kilometers. We still need to search the seabed. What methods should we use to search?"

Lin Yuan said: "Let's just use the submersible to search the seabed. On the seabed more than 1,000 meters deep, the visible light detection method is no longer useful, because it is already pitch black if it is 100 meters under the water.

Sonar is not easy to use, and all we can use is magnetic detection. The transport ship is made of steel and has a large magnetic field. The deep submersible will definitely be able to discover it."

Xu Siyuan agreed, Lin Yuan looked at his watch, it was already past eight o'clock in the morning, and then said, "Okay, today's meeting will be here. Everyone has been busy all night. Go back and have a rest. What's going on later will happen.

It's even more difficult."

At this time, Xu Siyuan came over and said, "For the boat we took to take on to sea, let's use the "Sea Survey" ocean surveying ship. It can carry a deep submersible. When will we set off?"

The "Search Sea" marine surveying ship is an ocean detection ship used to detect the hydrology, meteorology and other conditions of the ocean. These situations have a great impact on the navy's operations. The ship's empty-load displacement is 10,000 tons and full load

The displacement is 15,000 tons, the ship is equipped with a variety of marine detection equipment, and even sonar detection equipment to detect the seabed situation.

However, the sonar detector on the Pursuant Sea can only be used to detect the undulation of the seabed terrain, and there is no way to find the wrecked ship under the water. Although the size of the 10,000 tons is not small, with a length of more than 150 meters and a width of 10,000 meters.

It is more than 40 meters, but compared with the seabed terrain calculated over thousands of meters, it is a drop in the ocean, so the sonar detector is completely unable to find the wreck from the seabed.

Lin Yuan listened to Xu Siyuan's words and said, "Everyone is already very tired, let everyone rest first. Anyway, the ship has sunk for several hours, so there is no longer any survivors who need rescue, and we cannot rule out the shock of Wanlili.

The Tao is possible to be sunk by the enemy, so we also need to wait for the warship to come back."

Xu Siyuan said: "Our two warships are heading towards us and are expected to arrive at us at twelve noon."

Lin Yuan said: "Okay, let's set off at 1:00 pm and tell the patrolman that they can prepare the deep-dive robot." After Lin Yuan said that, he asked everyone to leave. As soon as he returned to the resting place, the Ministry of Foreign Affairs issued a letter.

News: "Report to Shuai Lin, the Japanese broke the appointment again."

Lin Yuan asked, "What's going on? Tell me in detail."

The Minister of Foreign Affairs said: "That's right. Last night, the Japanese liaison officer came back and said that their train did not come yesterday because of a mechanical failure. They had already repaired it. They sent the train again at 4 a.m. today.

At four o'clock in the morning, they broke the appointment again, but the train still did not appear."

Lin Yuan thought to himself: "What are the Japanese doing this?" So Lin Yuan asked: "Is there anything unusual about the Japanese army?"

The Minister of Foreign Affairs said: "According to the comrades in the army, there is no trend of attack in the Japanese 9th Division."

Lin Yuan said, "Okay, I understand. The Japanese will not cry until they see the coffin. I will rob them several of their large merchant ships and let them know well!"

Lin Yuan contacted Yu Feng and asked him to hijack the merchant ship to Japan more! Lin Yuan put down the communicator and saw Xu Siyuan walking in with a middle-aged officer and said, "Ship Lin, this is the general of the deep submersible force.

Commander, He Rui, he wants to discuss the submersible with you."

Lin Yuan hurriedly said, "So that's the case, then okay, please sit down."

The three of them sat down at the table, and He Rui said, "Shuai Lin, there are two types of deep submersibles here, one is controlled by someone, and the other is unmanned. The controlled by someone is better able to adapt to the requirements of multi-tasks.

There are many things that can be done, but the speed underwater is relatively slow. For example, our manned submersible has a cruising speed of only one knot, while our unmanned submersible has a cruising speed of thirty knots."

Lin Yuan thought for a while and said, "Then bring them all, so that we can perform a variety of tasks." He Rui agreed and went back to prepare. At one o'clock in the afternoon, Lin Yuan came to the marine surveying ship of the Purgatory Sea and ordered the Purgatory Sea to set off.
