The entire interception area was determined to be a square with a side length of one hundred and fifty nautical miles.

It was not an easy task to search for a main fleet of sirens in this area of more than 10,000 square nautical miles.

In fact, the Navy Administration also wants to provide accurate coordinates to the commanders, but they really can't do it, and it is already rare to be able to give a vague range according to the final course and speed of the sirens.

It is better to have a search range for the fleet than to let the fleet scatter around in this vast sea and search aimlessly.

Wang Yu looked at the range of the intercepted sea area, touched his chin and thought for a moment.

Most of the sea is empty, with only a few islands in the eastern part of the sea.

The islands are too scattered and not large enough to provide a combat advantage.

It seems that this battle will not be able to rely on the terrain, and can only collide with the sirens on the high seas.

The question now before Wang Yu is how to find the target as quickly as possible.

As an aside, the shipwrecks of this world have their own siren early warning function.

They have an out-of-line-of-sight detection ability for sirens in an attacking stance, but if they want to spot a sirens sailing silently, they must first get within the minimum concealment range of the sirens.

Back to the point.

In Wang Yu's opinion, the best way now is to let the three destroyers do their job and disperse to search for targets with maximum efficiency.

Of course, if it was before the crossing, he would never dare to do it.

In the last world, human ships did not have the blessing of the ship's mother, and they were easy to be discovered by the sirens, to put it bluntly, the concealment of the sirens in the silent sailing state was better than that of the warships made by humans, so the initiative was in the hands of the sirens.

So the best thing to do is to act in a group.

But this world has a ship mother, and the battleship theoretically has a similar concealment value setting to the siren.

And the ship's mother can even further increase concealment through the mind chip to reduce the range of being discovered by the sirens.

Although depending on the battleship, the concealment value brought by this ship is also different, and it is better and worse than the same type of ship of the siren.

But in this way, it can still greatly reduce the ability to be discovered by the sirens.

This time, the concealment of the three Yangyan-class destroyers is not bad, and they can do "stealth" reconnaissance.

This is also the confidence of Wang Yu to dare to let the fleet disperse for large-scale reconnaissance - after all, for the three destroyers, they can be the first to discover the sirens before they are discovered.

Well, that's it.

Wang Yu tapped his knuckles on the map, and then asked Anna to tell the three destroyer girls about this decision.

They were also highly skilled destroyers, and they understood the meaning of these plans, and they were also very familiar with the covert reconnaissance of the Kasein, so after receiving the order from Anna's side, they immediately began to leave the side of the Annapolis and left in three directions.

As night fell, the three destroyers quickly disappeared from Wang Yu's sight.

"As for us, keep on course." Wang Yu said to Anna: "No matter which reconnaissance destroyer finds the target, we can immediately go to support." ”

Anna nodded slightly, she looked at the night outside the window: "Commander, leave it to me next, you go and take a rest." ”

Wang Yu checked the map again, the battleship had entered the interception area at this time, although he wanted to pretend to be in the bridge, but he also knew that he really had nothing more to do before discovering the siren.

Plus, he also knew that his flesh and blood couldn't compare to Anna.

So it's better to rest early and recharge for the battle that will break out in the evening.

Eventually, he made his way to the commander's cabin below deck.

Anna looked at his back and didn't withdraw her gaze until he left.

…………

Wang Yu had a dream.

He dreamed that he was sitting in a pure black space.

There was no light around, and the environment was so dark that he couldn't even see his body, as if he had suddenly gone blind.

But even so, he always felt that someone was watching him in this boundless darkness.

It's the feeling of having an eye behind you that stares at you all the time.

Maybe no one was peeping at him, it was just an illusion in Wang Yu's own dream.

But this feeling of not knowing whether it is an illusion or a real peep makes Wang Yu extremely uncomfortable.

At the same time, walking in this black space, he also felt extremely depressed.

He wanted to get out of this place.

Perhaps this psychological suggestion had an effect, and he suddenly noticed that the black sky suddenly brightened......

Then he woke up from his dream.

Or, to put it more precisely, he was forcibly screamed.

Before he could complain about the strange dream, he noticed Anna standing by his bedside, gently shaking his shoulders.

Seeing her commander open his eyes, she spoke, "Miss Lan, who is in charge of reconnaissance, has discovered the siren. ”

Although his brain was inevitably sluggish when he just woke up, the word "siren" was enough to wake him up.

He didn't even bother to pay attention to the dream just now, as long as it was a nightmare.

Wang Yu immediately rubbed his face twice, then got up, grabbed the coat hanging on the head of the bed and draped it on his body.

He knew what it was like now, and he only took off his coat and shoes when he went to sleep, and he slept with his clothes.

Then he sped through the open hatch, Anna following closely behind him.

The two of them, one person and one ship, to be exact, returned to the bridge.

He glanced at his watch and realized that he had slept for about three hours, and it was almost midnight.

Well, a simple night's sleep should be enough for a night's worth of energy.

Wang Yu looked at the sea, the sky outside was dark, the weather was not very good, the moonlight was hidden behind the clouds, making the visual visibility even worse.

Naturally, he couldn't see any enemy ships.

Nonsense, after all, it was the siren found by the destroyer Arashi, and the destroyer was now estimated to be some distance away from Annapolis.

Within a certain distance,There is the ability of "psychic communication" between ship girls.,This ability will not be interfered with by the sirens.,So it has a very good effect when fighting against the siren.,It's much stronger than the radio that is jammed at every turn.。

"Where is Arashi?" Wang Yu looked at the map and asked.

Anna's slender fingers pinpointed the location of herself and Arashi on the map, and explained, "Miss Lan left in the direction of our port side before, and it is about forty nautical miles away from us in a straight line. ”

Wang Yu looked at the map, and the current position of Lan was about thirty degrees south-east of Annapolis.

"What about the siren location and hostile situation she reported?"

"She spotted a siren destroyer about ten minutes ago, and then slowly approached it with the promise that she wouldn't find it, and then spotted another destroyer, as well as a siren heavy cruiser."

The concealment of the Sirens sailing silently was about fifteen nautical miles, which was about the same as the sight distance.

Therefore, it is entirely possible that Arashi first discovered the Siren destroyer that was closer to her, and then found the Siren Heavy Cruise, which was far away but poorly concealed.

Anna's words were clear, Wang Yu could already imagine that the small destroyer was slowly touching the direction of the siren fleet under the nose of the sirens, relying on the concealment value, and then found more targets.

"Did Arashi say this was our goal?"

She said she couldn't go any further, because she might be spotted by the sirens.

When Wang Yu heard this, he couldn't help frowning.

That's a bit of a hassle.

In this interception area, there are not only the main Sirens as targets, but also those possible free Sirens - there are no battleships that can be conclusive among the Sirens that Arashi has observed, so it is still possible to have both outcomes.

Wang Yu's fingers tapped rhythmically on the map on the table, which was his little habit when thinking.

So, is it necessary to turn Annapolis around?
