Zhang Tao remotely controlled five submarines back to Iceland, filled three submarines with fuel and filled kegs of diesel fuel and then remotely controlled them to set off towards the Norwegian Sea, and after the last submarine was hidden on the seabed ten days later, Zhang Tao remotely controlled the small submarine to turn on the infrasound and communication functions of polar bears and other marine animals, so that it could stick to the surrounding ice floe.

After seeing that the small submarine was fixed, Zhang Tao came to the factory laboratory, this time the submarine was in the RB Sea, it was autumn season, and there was no floating debris on the sea, but there was some seaweed, but the seaweed would not move on its own.

Zhang Tao thought about camouflaging the small submarine in the shape of a leatherback turtle, input the data of the small submarine's shell into the computer, and used software to simulate a leatherback turtle model that was larger than the small submarine, and input the model's length, width, height, arc and other data into the computer of the forging machine. A leatherback sea turtle weighs about two meters and one ton, which is about the same weight as a small submarine.

Several layers of stainless steel plates were placed in the raw material mouth of the section bed, and the operation procedure was followed to create a model of a leatherback sea turtle, and then a layer of black lacquer was applied to the model.

The manufactured steel turtle shell is divided into two parts, it is opened and buckled on the submarine, there is a rubber layer in the steel turtle shell that can play the role of sticking and shock absorption, and the front and rear propellers are at the front and rear ends of the turtle shell.

Zhang Tao also built several small submarines in the shape of a fish, this time completely replicating the shape and paddling pattern of the fish. The shell is also forged and formed with a section bed of stainless steel plates. The head of the fish is equipped with an infrasonic device and a signal transceiver, there are two cameras in the eye part of the fish, the belly of the fish is equipped with a small water pressure chamber engine, a diesel engine and a container for diesel fuel and some gears, the tail and fin part are pieces of aluminum alloy plates, and the gills are the inlet and outlet and smoke exhaust port for entering and exiting the seawater.

After the fish-shaped submarine was done, it did a lot of pressure resistance and cold and heat experiments, and then put it in the seawater by the sea to do some experiments, except for the slower speed, there is no problem, when you look at it from a distance, it is similar to a real fish, Zhang Tao plans to remotely control it under the seabed at night, so that it can not be seen.

In the evening, Zhang Tao covered the dock with a black shade cloth and used a truck to pull the contents of the two submarines to the dock. After loading the things into the submarine, he remotely controlled the two submarines and set off according to the route of the previous three submarines.

After passing through the Norwegian Sea, the submarine entered the Barents Sea, and there is a small town on New Alesund Island in the Barents Sea, on which there are more than 60 houses that are scientific research sites of some countries, including the Yellow River Station, China's Arctic scientific research site.

Out of the Barents Sea, it turned fifteen degrees to the right towards the Bering Strait, passing through Russian islands and seas, and there were no countries in the Arctic Ocean, so there were few ships cruising.

The Bering Strait also has an area of the open sea, and when it was night in the Bering Strait, Zhang Tao remotely controlled two submarines to drive through the Bering Strait at a speed of 20 knots per hour. After reaching the wide surface of the Bering Sea, the submarine was restored to a speed of 30 knots per hour, and sailed towards the Sea of Japan in the Russian waters of the North Pacific Ocean.

There were many ships in the North Pacific, and the submarines were all out by day and night, and arrived near the Tsugaru Strait after more than 10 days. The Tsugaru Strait is the only area in northern Japan that does not freeze all year round, and the October season is warmer than other seas, and the submarine camera shows more fish than in some other parts of the North Pacific.

Zhang Tao remotely controlled two submarines to the inner bay, there were not many ships on the sea at night, and after midnight they arrived at the sea area near the coast of the inner bay, reducing the speed of the submarine to ten knots per hour, and at the same time putting a small submarine disguised as a leatherback turtle into the sea.

Remotely control the small submarine to float to the surface and drive forward. At night, the sea water is black and the color of the leatherback turtle is integrated, and the submarine under the surface of the sea quickly dives to a hundred meters to the bottom of the sea and moves forward, the sound wave transmission range of the small submarine is within a radius of one kilometer, and the range of the submarine and the distance of the small submarine cannot be too far, so the speed is reduced to the same speed as the small submarine.

Looking at the computer time display that it is eight o'clock in the evening, the time in Japan should be two o'clock in the morning, judging from the video transmitted by the small submarine, the sea is still dark, and after an hour, the submarine and the small submarine are near the coast.

Remotely control the submarine to find a trench on the bottom of the sea, open the resonance frequency of the stone in the trench to shake out a hole, drive in to hide the hole collapse, as for the small submarine disguised as a leatherback turtle, it is to turn on the frequency of some marine animals, and also turn on the early warning of ships and metal objects, there are generally no large marine animals in the near sea, so that they stop in place thirty meters below the sea surface.

Zhang Tao washed up and slept in the computer room, and when he got up the next day, he watched the video of the small submarine and still stayed at 30 meters under the sea, and the current time in the Sea of Japan is two o'clock in the afternoon, and it will be dark in about six hours, and there are more ships coming and going on the sea at this time.

Six hours passed, and there were more than a dozen ships passing above the small submarine, and when it was 500 meters away from the small submarine, it was detected, and the computer sounded an early warning alarm, and Zhang Tao adjusted the position of the small submarine to avoid the large-tonnage ships touching it.

Looking at the video sent back by the small submarine, it was getting darker and darker, and when it was completely dark, there were no passing boats. Zhang Tao remotely controlled the two submarines in the submarine cave through the small submarine relay signal, completely shattered the stones at the entrance of the cave and drove out.

Searching the sea area of Muroda City to Nagamanbe Town did not yield, and when I searched the sea area of Yakumo Town in the middle of the night, I found that there was a different terrain from the general seabed at the bottom of the sea, and I saw that the time was almost up, and I wrote down the latitude and longitude of the location of this sea area, and remotely controlled the submarine to find a trench and open the vibration frequency of the stones, and open up a cave to hide.

A day later, it was dark again, Zhang Tao remotely controlled the submarine to the bottom of the sea where he searched yesterday, released the fish-shaped small submarine, swam forward for 800 meters and then came to the bottom of the sea, and found that the seabed was a piece of cinder and broken bricks, and the fish-shaped submarine was remotely controlled to use the aluminum alloy sheet at the tail to peel off some cinders and bricks and tiles, and after turning the fish head, he saw that some black things were exposed, and the focal length was enlarged to be some coal.

After returning to the submarine with a remote control of the fish-shaped submarine, he drove forward for a nautical mile, and then said that the fish-shaped small submarine was released to check that it was still coal. In the middle of the night, after inspecting the entire seabed covered with cinders and broken bricks, it was determined that the area was full of coal. (To be continued.) )
