Beibu Gulf.

The depth of the seabed is around 184 meters.

A huge black fish lurking here quietly.

Inside the black fish, many people were busy in silence. Captain Ruan Shahe took the lunch box sent by his subordinates and started eating silently.

The deputy captain on the side took his place and began to direct the operation of the submarine.

Although the Kirov class is known as an oceanic black hole, China has also imported a large number of this submarine, and the other party has long known the voice patterns of the Kirov class.

Now they are in an ultra-low speed state, with a speed of only about 8 knots per hour, minimizing their own noise as much as possible and avoiding being discovered.

It’s a pity that they didn’t know that the submarine had been targeted long ago.

The sea area of ​​Beibu Gulf is too small. Compared with the vast Pacific Ocean, it is like a small pond. These black fish were not accurately caught before because of Kirov's outstanding performance and also because of vulgar noise reduction.

At this time, more than a dozen wind ears have been arranged in the South China Sea area, and when the wind ears are used as fixed sonar points, they can start the active sonar mode.

With the assistance of active sonar, these black fish soon disappeared.

The deputy captain who was driving a submarine carefully adjusted the route. After all, today is different from the past, and they can't afford to offend powerful neighbors in the north at all.

Suddenly he felt something was wrong, because on the passive sonar equipment, there were three destroyers nearby, approaching here.

He stared at the instrument with a nervous expression and found that the three destroyers seemed to have discovered them. He hurriedly adjusted the route and moved to the west sea area.

But as soon as he changed his direction, the other party also changed his direction of letting go, as if he was following him like a shadow.

The deputy captain, who felt something was wrong, hurriedly pulled La Ruan Shahe's sleeve and compared it with a special gesture of emergency.

Suddenly, Ruan Shahe didn't care about eating anymore and hurriedly stared at the sonar detection panel. Sure enough, there were three green light spots following them like shadows.

For the next half hour, both sides played hide-and-seek in the sea area, but no matter how Ruan Shahe and others changed their routes or directly attached them to the seabed, they could not escape the other party's tracking.

With no choice but to withdraw from the high seas and return to his own territory.

After returning to the territory, Ruan Shahe was not in the mood to continue the mission, but instead directed the submarine to return to the home port.

He had just returned to his home port and was about to report on this matter. He found that other submarines had also returned to his home port one after another. After discussing with several captains for a while, everyone encountered the same situation.

"Damn it, how did they find us?"

"It's no reason!"

"It is difficult to detect at low speeds. Even if the other party has Kirov's voiceprints, it is impossible to be so accurate."

Ruan Shahe was also in lingering fear, but he calmly suggested: "Let's report this matter as soon as possible! It's a headache for the superior."

"Um."

Everyone summarized the situation and wrote a joint report to report today's affairs.

At the same time, the same scene also appeared on the home port of several other submarines. This incident quickly attracted attention. After studying it for a long time, I found that I was helpless.

After all, the Kirov class is already their bottom line, and it is imported from Lucia, and the ones produced by themselves are even weaker.

Even the Kirov class has nowhere to hide, so their submarines have basically become waste. After all, the submarines rely on are concealment. Submarines that cannot be concealed are even worse than destroyers.

In the next week, Ruan Shahe and others tried several times. Even when they set out from their home port, they would quietly move forward quickly. As soon as they entered the high seas, the destroyer would be immediately targeted.

It seemed as if there was an invisible eye, watching their every move in secret.

This feeling made Ruan Shahe and others very scared. In this claustrophobic environment, coupled with the terrible pressure, many people even had serious mental problems.

In the end, there was no way, so they had to suspend the submarine cruise mission.

After all, when people leave the port and are accompanied by people throughout the journey, the strategic deterrence of the submarine is basically zero. If it really fights, it will be a few deep-water bombs.

Seeing that they were powerless to turn things around, they didn't waste their energy and simply pulled the submarine back.

On the other side.

The three marine garbage cleaning fleets are divided into several directions, fishing for marine garbage in various sea areas of the South China Sea.

Near the Dongsha Shoal, there are no other islands here except for the newly filled New Dongsha Island that has just been blown up.

He was responsible for cleaning up a garbage cleaning boat in the sea area and soon discovered some abandoned fishing nets, plastic bottles, etc. The crew member Xiong Kuan started the salvage system and recycled the waste.

Zhao Xinmin, a data tool tracker on the side, held a specially made tablet computer with a satellite communication system connected to the cleaning ship, which could get careful feedback.

The cleaning ship itself is also equipped with a tailwind ear sonar system. Although it is a restricted version and can only be detected as a 50-kilometer marine item, this system is also specially designed to clean up marine garbage.

By sacrificing the detection distance, higher accuracy is obtained.

On Zhao Xinmin's tablet, you can clearly see floating objects, submersibles, and fishes in the vicinity within 50 kilometers.

"Big Bear, at 10:35 northwest, around 450 meters, there is an abandoned tire."

The taciturn Xiong Kuan adjusted the direction, pressed the launch switch, and a large net shot 450 meters away.

When the fishing net was pulled up, there were not only tires, but also some boat wood, plastic foam, and dozens of fish.

After eating fish for more than ten days, Xiong Kuan felt nauseous when he saw the fish, threw the fish back into the sea and then dumped the garbage into the garbage storage compartment.

In the garbage storage compartment, there are many strange garbage, tires, foam boxes, plastic bottles, straws, fishing nets, nylon ropes, etc., and there are also a small number of glass bottles, boat wood and iron boxes.

There is even an abandoned inflatable doll, which may appear in all kinds of strange things.

Suddenly, the captain's loud voice rang out on the walkie-talkie: "Everyone work harder, prepare to return at 3:30 this afternoon."

"Head, why are you going back so quickly? There are still one-third of the space left in the garbage storage compartment." Zhao Xinmin asked in confusion.

The captain explained: "Typhoon, I just received a notice from the maritime department that the periphery of the typhoon has approached the Zhongsha Atoll."

"All right!"

When everyone heard the typhoon, they could only avoid the edge.

After lunch, Zhao Xinmin found several big targets and prepared to do the big ones in the end, and then return to the voyage to the city port.

It was around 1:30 p.m.

The garbage cleaning boat came to the nearest of the first target. After fishing it up, it found that it was an abandoned small air hoverboat. Xiong Kuan glanced at the trademark on it and found that it was an ordinary lifeboat.

Near the second target, after one net.

Xiong Kuan exclaimed: "A big fish, please be careful."

Although they are equipped with exoskeletons, the thing in front of them is an abandoned torpedo. If an explosive device is triggered, their small boats of more than 5,000 tons cannot withstand the torpedo destruction.

Carefully pulling the abandoned torpedo closer, Xiong Kuan quickly determined which region it was produced.

"Head, no value."

"Then let's detonate!"

"Okay." Xiong Kuan jumped off the boat on the side, drove to the abandoned torpedo, and stuck something similar to a plastic bomb on the warhead, setting it to detonate for half an hour.

Half an hour later, the garbage cleaning ship had already begun to return north.
Chapter completed!
