As the saying goes, if there is a problem, it must be solved.

Venice and Milan, in addition to the degree of training, the problems exposed in the battle also have some wrong ideas about the battle.

So after their first battle, Anna called them to the Annapolis.

In the eyes of the two cute new ship girls, Anna used very good understanding words, concisely summarized the problems shown by the two ship girls in the previous battle, her tone was flat, but it had undoubted gold content.

For example, in battle, Venice often performs some unnecessary maneuvers, even if the siren's cannonball has not yet hit, she has a tendency to constantly change her course and attitude, rather than observing the siren's attack to avoid it instantly.

Milan, on the other hand, was not prepared to maneuver defensively during the attack, and during the battle, she gave Venice all the task of withstanding the Siren's attack, and she carried out the fire projection regardless of whether she was maneuvering or not.

It can only be said that maybe this idea does work in this world.

Find a wound-resistant close range to hold the siren's hatred, while the rest of the teammates go crazy.

However, in Wang Yu and Anna's thoughts, the girls in the fleet are not just sirens who need to face this world.

In the future, they will need to face the Siren fleet of the previous world's threat level, and at that time, this attitude of believing that friends can hold back their hatred and then export it themselves defenselessly is certainly not worth advocating.

The sudden change of target of the sirens will catch people off guard.

Wang Yu didn't plan to just let them train according to the intensity of the siren battle in this world, he wanted his ship girls to know how complicated the intrigue between the two sides was when they really fought the sirens.

In short, Anna explained the problems exposed in the battle to the two ship girls in turn according to the order of the timeline, and how to correct them, and Wang Yu was on the side, although he also gave a little advice from time to time, but most of the time he just handed over the responsibility of teaching the two girls to Anna, who was also a ship girl, and later, he didn't say a word.

He found that although Anna didn't talk much at this time and her movements were very small, her temperament was quite charming, and he was a little fascinated unconsciously, huh......

"Commander, what's wrong?"

Anna's voice startled him.

Wang Yu raised his eyes to look, but found that Anna had stopped explaining at some point and was looking at this side seriously.

He hurriedly pulled his collar as if he had been found as a thief, and then glanced at the watch hanging in the bridge: "Cough, it's nothing, I just think what you said is very good, what, where are you talking now?" ”

"That's it."

Anna came to Wang Yu, stretched out her hand to help Wang Yu straighten the collar that had just been messed up by him, and then looked at his expression, and said with a little worry: "Commander, you seem to be a little tired, are you tired?" ”

Wang Yu did seem to feel a little sleepy.

He nodded subconsciously: "It seems to be a little tired." ”

"Is it because the Commander hasn't rested today?" Milan joined in the excitement next to him: "After all, it's been a long time since we entered this sea, do you want me to make some dessert for the commander?" ”

Wang Yu looked up at the porthole, and the sunset had already appeared on the sea level in the distance.

Fighting, summing up, before you know it's evening.

"No, you can go and help Anna prepare dinner." He said this and yawned at the same time - it was strange, he didn't feel anything before, but after Anna said this to herself, he began to feel tired: "I need to go and rest for a while, call me ...... when I eat"

"Hmm."

Anna looked at him with concern for a moment, then nodded.

…………

For the next few days, the three warships continued to cruise and fight in this first-class sea area.

When there is no battle, you can also improve the training of the ship's mother.

For example, during the cruise, Anna will take the lead in some maneuvers, and then Venice and Milan will follow her and imitate; Or Anna sometimes gives the two shipwives some instructions (such as keeping XX speed and turning to XXX direction in XX time) for them to do.

This kind of training will help them learn how to use their hull to maneuver faster.

For example, how to rudder at the right time, how much to rudder when to rudder, when to start rudding back when you are about to turn to the target position so that you don't turn your head, or the steering radius of the full rudder at different speeds......

Although Venice and Milan did not perform well at first, they had difficulty keeping up with Anna's maneuvers, or completing Anna's instructions to them, often scattering the original fleet after a single operation, and then spending a lot of time regrouping back into a neat formation.

However, as this process was repeated during the cruise, they naturally summed up some experience in controlling the hull.

Slowly, they found themselves able to maneuver the ship with the Annapolis in front of them, following the trail of the latter's wake on the surface of the sea, and gaining better control of its direction.

When fighting, they also have a lot less pointless maneuvers to evade.

It is also more handy in the process of adjusting the direction of the battleship.

When the fleet was disbanded and regrouped, they controlled the hull to join the formation, and kept the battleship on the side of the Annapolis, which took much less time than before.

This is the improvement of training.

Anna told Venice and Milan for sure, which had excited them for a while.

After all, improving the degree of training is an obsession in their hearts.

Even if they can't do it smoothly and accurately while doing it for the time being, the improvement is always good.

Wang Yu has always believed that wine should be drunk one bite at a time, and the road should be walked step by step.

Although the ship girls don't have that part, their body flexibility is undoubtedly strong, but this is a metaphor after all.

To put it simply, although Wang Yu wants to improve the training of the two girls in Venice and Milan, he does not have any idea of quick success, so at this time, even if it is only a small progress, he is happy for Venice and Milan.

In addition to sailing training, Wang Yu did not forget to train the combat skills of the two shipwives.

Step by step, he did not immediately bring Venice and Milan to face the most "powerful" enemies in this sea.

Instead, Anna's radar is used to increase the number and intensity of the enemies that Venice and Milan will face in each battle, in a step-by-step order.

After a few days patrolling the area, they fought six more battles.

Of these six battles, five were fought independently by the two battleships of Venice and Milan.

The sixth battle was more than Venice and Milan could currently cope with due to the increased number of sirens.

When a siren destroyer unexpectedly got close enough to release a threatening torpedo, Anna opened fire when neither Venice nor Milan could effectively attack, and three consecutive shots killed the escaped siren expel in an instant.

But the current Venice and Milan can't do it without being able to brush off so many sirens.

In the end, both Venice and Milan suffered some minor injuries to their hulls.

They were hit a few times against the Siren Heavy Patrol and Light Patrol, but fortunately the Sirens' shells did not deal too much effective damage, only damaging some of the decks and hulls.

This damage is back in the shipyard and can be completely repaired in an hour, so it doesn't matter.

In all, a large number of Siren cruisers and destroyers were destroyed in six battles, and even three Siren cruisers were killed.

In this sea area where the Sirens are of one rank, the Heavy Patrol is the strongest warship of the Sirens.

The three Sirens unleashed a total of one trophy.

Recovered by Miss Venice after the battle, Wang Yu obtains an inactive Mind Core.

Although it's not a pity that the chip that has improved significantly from the ship mother, the mental core is not lost.

And Venice and Milan have also improved their combat skills in these battles.

Their coordination is more intelligent, their targeting choices are more realistic, and their gunnery has improved - the average time it takes to destroy at least one siren ship of the same caliber is decreasing.

Although they still need to be honed many times of the same battle before they reach full training, their training has improved.

For now, at least, they have the strength to fight the Sirens.

It's always good to have an improvement.

According to Anna's radar detection, there is currently only one siren fleet left in the sea, and once this siren fleet is killed, then this sea area will temporarily become a safe area.

Anna originally wanted to take this last battle as a "test" for the two shipwives of Venice and Milan, but what she didn't expect was that when approaching the siren fleet, Wang Yu fell ill very unexpectedly.

This disease has been a harbinger for some time.

The first symptoms are occasional chills, which are mainly manifested by fatigue and drowsiness.

Wang Yu thought he had a cold at first, so he didn't pay too much attention to it, just ate more fruits and drank more hot water.

But soon, the disease became a more serious symptom.

He began to have pain and a high fever, and he lay in bed as if he had collapsed - if it weren't for Anna's constant monitoring...... Well, always pay attention to Wang Yu's physical state, it is estimated that it will be difficult to find out his situation at the first time.

Anna hurriedly took out some symptomatic medicines from Wang Yu's cabin and gave them to him (it is normal to put all kinds of emergency medicines on the battleship), which slightly alleviated some of Wang Yu's symptoms, but the effect was not obvious.

Anna was worried.

Although Wang Yu was groggy, he listened to Anna talk about the symptoms in a moment of wakefulness, so he thought that it should be caused by some kind of virus from another world with similar symptoms, but different treatment drugs.

Speaking of which, if you think about it carefully, it should have been a rain that still hasn't faded away two days ago, and the virus invaded by Wang Yu who didn't change his wet clothes in time after being wet by the rain.

He was indeed a little negligent.

Even if this world is similar to the previous world, there will be some viruses that did not exist at all in the previous world, and there are no antibodies against those viruses in your body, so you can only use immunity to resist now.

Fortunately, Wang Yu's health is good, and his immunity is not bad, except for being uncomfortable, he does not feel more intense "symptoms" for the time being.

So as long as the condition doesn't worsen, you shouldn't worry too much.

Speaking of which, how did those time-travelers manage to be completely immune to the brand-new viruses of that world after physically traveling to another world?

It's really poisonous.

Wang Yu now wishes he had such a body.

By the time he fell ill, the fleet was already preparing for battle with the sirens and could not quickly withdraw from the battlefield.

So Anna weighed it, and she immediately made Venice and Milan abandon their original battle plans, and followed her, and it took three warships less than twenty minutes to send the free siren fleet to the bottom of the sea.

Venice and Milan were also seeing Annapolis' powerful fighting abilities for the first time, so they immediately asked for some combat skills.

But this time Anna was not in the mood to teach them, she was worried about Wang Yu's health, so as soon as the battle was over, she let the two battleships of Venice and Milan follow her back to Habara's port area at maximum speed.

Venice and Milan also learned that Wang Yu was suffering from a strange illness, and although they also wanted to stay with the commander, Anna only allowed them to visit them for a short time, on the grounds that "too many people here might disturb the commander's rest".

They had nothing to say about it.

Wang Yu temporarily handed over the responsibility of commanding the return of the fleet to Anna, who was now dizzy for most of the day, unable to think effectively, so he could only huddle in his cabin, cover the quilt and wake up and sleep.

Often, when you wake up for a while, you feel sleepy, and then you fall asleep again, and when you wake up again, you find that it has been a long time later - but this sleep is not very peaceful, and nightmares come with sleep, which makes people even more uncomfortable.

Anna looked distressed, but she could only hold Wang Yu's hand while he was struggling in the nightmare, and at the same time wipe the sweat stains from his forehead with a cool towel.

She naturally took on the responsibility of taking care of Wang Yu.

Fortunately, even if Wang Yu fell ill, the physique that was difficult to seasick was still maintained, so when the fleet maintained a high speed of more than thirty knots and went north, he did not get seasick because of this.

Anna felt that since it was some kind of disease in this world, then Habara Mio should have the right medicine - even if it didn't, the environment on land would be more suitable for healing than in the cabin of a warship on this ocean-going sea.

So, as long as you go back to Minato, everything will be fine.
