The next proving ground basically became the performance ground of Annapolis.

In the blink of an eye, Annapolis had completed the attack on all the islands marked, ending this short training.

If you are facing a siren, then it means that a small team of sirens has sunk into the sea.

Wang Yu did not hesitate to praise himself, and he gave the girl a round of applause.

For Wang Yu's straight ball praise, Anna did not show any special expression.

She felt that this was not a record worthy of praise, and every ship's mother should be able to do it.

What she would prefer now is to prove herself to the commander in real combat.

"Now that the test is complete, let's go back."

"Commander, actually, ......"

Anna took the initiative to speak: "The naval gun has unlocked some modes that were not available before, and I want to show you this." ”

Wang Yu raised his eyebrows, what other modes does the naval gun have?

He nodded: "Then let's show it, by the way, there is one more thing, don't use 'you' to call me in the future, it will make us a little distant, after all, we should be closer, shouldn't we?" ”

"Since the commander has said so, okay."

Anna chuckled: "What I'm going to show is another firing mode of naval guns. ”

What other firing modes does the main gun have?

Wang Yu motioned for her to start the show, and then he came to the porthole and looked at the two main guns in the bow.

Anna didn't know what order to give to the ship's hull, and Wang Yu heard the sound of the main gun being loaded.

"Alternate Shooting Mode, also known as Burst Shooting Mode." Anna's nice voice took the initiative to attach an explanation: "Commander, please enjoy." ”

Subsequently, naval guns fired a salvo at one of the targeted islands.

Wang Yu was about to say that this was not a salvo, but in the next moment, he swallowed it back directly.

Because the naval guns did not stop.

Less than a second after the first salvo, the second salvo was fired, and after a short delay in the completion of the second salvo, the third salvo was fired – the fire clouds and smoke from the previous round were dispersed by the shock wave of the second round of shelling, and in less than three seconds, a total of thirty-six shells were poured out.

After three salvos, the ship's guns stopped roaring, and the turrets began to rotate back to their positions.

Wang Yu was directly shocked.

The fireballs that flashed one after another just now were directly engraved in his mind, and the successive dense cannon sounds made his brain tremble, and he still felt that the bridge was vibrating slightly because of the back seat.

This...... It's a really memorable shooting mode.

In a very short period of time, a full three salvos were fired, and the instantaneous projection was more terrifying than those light cruisers.

Anna didn't let him doubt for too long, and quickly gave an answer - this is a salvo mode that she used the power of the ship mother to achieve, that is, she directly locked the original mechanical loading device, and directly used the ability of the ship mother to take out three shells from the lifting shaft and line up in front of the bolt, and immediately loaded one shot after firing, so as to actively speed up the loading speed of the ship's guns.

However, since it takes time to unlock the locked reloaders and then allow the hot barrel to cool down to avoid further wear, it takes about thirty seconds for the next shot to be fired after using these three salvos.

Wang Yu thought about it briefly and understood the advantages and disadvantages of this burst shooting mode.

The benefits are naturally obvious, providing an instantaneous burst - Annapolis is only 203 mm caliber after all, and most of the time against the sirens still relies on the projection volume to sink the sirens, so this means of instantly increasing the projection amount can be used in the face of some siren warships that are about to collapse, and can have an effect similar to slashing.

The disadvantage is that in the long run, Annapolis can usually do a round of five seconds, and continue to deliver firepower, and this burst shooting mode has to stop for 30 seconds to play three rounds, which is enough time to fire in a normal state for six rounds.

So in fact, you need to switch between shelling modes flexibly according to the battle situation.

For example, if you want to continue to output, use normal mode, and when the siren is about to go out of range, the siren's status is endangered, or you plan to stop firing and hide, you can use the burst mode to play a round of output.

This depends on Wang Yu, the commander's ability to judge the battle situation.

Thus, Annapolis ended its first sea trials here.

Wang Yu sent a report to Mio Habara, who was too lazy to ask what was going on with the three consecutive rounds - it should be regarded as a special technique from the previous era.

She didn't think about copying one according to this battleship at all, according to the special logic of the existence of the ship, when this battleship is too powerful, the requirements for generating the ship's mother are also higher, so even if she copies one as it is, there is a high probability that the ship's mother will not appear, which is equivalent to wasting materials and time in vain.

Led by the destroyer, the Annapolis returned to the fjord.

Under the condition that the battleship has been repaired, it is naturally impossible for Wang Yu to return to that closed shipyard to live.

However, Mio Habara has promised to help him and Anna solve the problem of housing, but that will take time.

So he can only live on the battleship for the time being.

However, Wang Yu didn't hate it, the captain's room of this battleship was relatively comfortable.

Mio Habara took the destroyer back to her port.

Annapolis anchored in a calm area of water outside the Habara Mio harbor area, which is also a benefit in the fjord, which is less affected by the waves, and the single anchor can ensure that the battleship does not drift around.

And after Mio Habara left completely, Wang Yu stretched his waist and was about to go to cook something and rest, but Anna stopped him.

"What's wrong?"

Wang Yu looked at this girl with a somewhat strange attitude.

"Commander, there's something I need to tell you...... You. Anna said seriously.

"What's so serious?" Wang Yu looked at the girl's expression and wanted to laugh a little: "Why didn't you say it just now?" ”

"It's not convenient just now, first, there are outsiders, and second, what I want to say is more time-consuming."

Anna said more this time, which was completely different from the impression she left on Wang Yu before: "In fact, I seem to be ...... I seem to have discovered the reason why we came into this world. ”

Wang Yu didn't have any expression.

To be precise, he didn't understand the meaning of the sentence at this moment.

The main thing is the tone in which Anna speaks, as if she is saying "what's going to eat tonight".

After a moment of silence, he reacted and looked at the girl with a stunned expression: "Clam?!" ”

After understanding, he found that the news shocked him too much.

I don't know anything after more than two months of crossing over, but you just knew it when you became conscious?

But he also knew that Anna wouldn't entertain herself with such things.

So he immediately put on a serious look: "You say it carefully, I'm listening." ”

"After assimilating the battleship, I did a self-examination of the entire hull." Anna's speed of speech remained unchanged, and she said softly: "Self-inspection of the hull is the instinct of the ship's mother, and it was this self-inspection that I found that my hull was equipped with a ...... Peculiar device. ”

"You're a super battleship, and there's strange ...... all over the hull" Before Wang Yu finished speaking, a thought flashed through his mind like lightning: "Wait, you're not talking about the 'siren containment'!" ”

Anna nodded in a slight but visible motion.

"Out of curiosity, I searched my memories of the device, and I learned about it."

When Wang Yu heard her say this, he hurriedly asked, "This is really an accident, I thought that thing was the culprit that attracted the sirens, but I really didn't think that it was the culprit that caused us to cross...... So you know what that thing is? ”

Anna nodded again.

Then she paused for a moment before speaking.

"That isosahedron is the third containment object of the Siren Containment Facility, codenamed SC(Siren_Containment)-003, called the Gate of Transition."
