Looking at the girl in front of him whose cheeks were crimson because of the anxious explanation, Wang Yu smiled kindly.

He thought of a good friend of his from the previous world.

That guy has a younger sister, who is not very old, but cute and loving, usually once she is misunderstood, she will blush when she is in a hurry to explain the situation, and every time she blushes, her friend will rub her little head and smile to soothe her emotions.

Friends, I don't know if I'll ever see them again.

Wang Yu retracted the distant thoughts in his mind and looked at Mio Habara, whose flush was slowly fading on his face.

He and the girl weren't that familiar with each other yet, so reaching out and touching his head to comfort him was spared.

Let her calm herself.

"I can understand why you're in a hurry to explain, but you don't have to be in such a hurry, in our day and age, ......"

Wang Yu emphasized "his identity" before speaking, and then continued: "In order to resist the sirens, it is very common to use siren technology, in fact, my battleship was built by integrating a lot of siren technology - this has the combat ability beyond ordinary warships. ”

In fact, what he said was true or false, making it difficult for listeners to catch any loopholes.

As for why the siren technology on the battleship was suddenly explained, it was mainly because at the beginning, Wang Yu was also worried that the world was biased against the siren technology, so he kept it hidden, but now he looks at it, good guy, your world plays with siren technology more than in the previous world, so he simply explained some of the situation on the battleship.

"Whew, that's good, that's good."

Mio Habara took two deep breaths and stroked her chest and said, "I thought I had done something wrong. ”

What a cute little girl.

"As for the maintenance of battleships......

Wang Yu set his eyes on the dock.

While it was hesitant to enter a Siren-based shipyard, he didn't have much of an alternative right now.

If the world had popularized the siren shipbuilding technique that Mio Hahara called in shipbuilding or ship repair, then it would probably be the same situation wherever he went.

However, before entering the dock, Wang Yu wanted to know more.

So he continued: "Can you first tell me how those equipment works, for example, how do these sirens repair my warship?" ”

"Hmm!"

Mio Habara immediately began to introduce: "The shipyard uses a ......"

With her words, Wang Yu understood the process of repair.

At the same time, he also knew the magic of this siren technology in ship maintenance.

These devices share a similar characteristic to other sirens, which is a high degree of automation.

First of all, when the ship is docked, the sensors arranged in the dock will automatically perform a comprehensive scan of the entire hull, which is not only limited to the outer contours of the hull, but also includes the internal structure of the battleship.

The scanned data is uploaded to the control core, the blue-glowing octahedron that Wang Yu saw, for analysis, and the automated device can come up with the best repair plan without human intervention.

According to Wang Yu's guess, this core seems to have used countless imaginable and unexpected ship design data as samples to train a neural network model with high fit and high credibility in ship design.

To sum up, when the battleship is parked, even if the battleship only has a rough outline, this core can deduce the original appearance of the battleship according to countless possibilities for building a ship, and carry out restorative repairs.

The entire shipyard then proceeds to the repair of the ship according to the maintenance plan.

In the process of maintenance, it is the perfect embodiment of black technology.

Siren shipyards use a one-piece molding technology similar to 3D printing when building or repairing ships.

According to Mio Habara, when building ships, the metal materials used to build ships are placed on the prisms around the docks through high-frequency particle vibrations, causing the metal atoms to move freely out of their original lattice state, thus transforming into a completely liquid state.

These flowing metals are bound by means similar to magnetic confinement, and then according to the "mold" of the ship, the density of these molten metals, which is much lower than that in the solid state, is directly "compressed" into the shape of a battleship.

In the process of compression, the density of the metal liquid increases, and the degree of freedom of the particles will also change, and under the control of the equipment, the metal particles return to the neatly arranged lattice state, and the reaction is at the macroscopic level, which is the rapid cooling and forming of the battleship.

The process of repairing the ship is similar, except that the above steps are used in the damaged area of the battleship, and the newly repaired area is perfectly integrated with the original hull, so that the battleship after the repair is completed can not even see a trace of damage.

In Wang Yu's opinion, this is simply an operation against the sky.

He knew that the sirens were highly technological, but he didn't expect the sirens to be so technologically high.

"Your world...... I mean, you know so much about sirens in your time? ”

With admiration and surprise, he looked at Mio Habara, who had just talked to him for a long time.

As a result, the girl hurriedly waved her hand: "No, these are just possibilities that researchers have speculated based on the results." ”

What she means is that the current research on sirens in this world is not sufficient, and there is obviously a black box of science and technology behind these siren technologies, and no one knows the real principle until now, and human beings are just simply able to use it.

To put it bluntly, give the monkey a button, press the button and give away a banana, so it is logical for the monkey to learn to press the button to take the banana.

But if you want the monkey to know the connection behind the button and the banana, that's the extremely difficult process.

Wang Yu had no choice but to shake his head.

The siren's technique is indeed difficult to understand.

The high technology possessed by the sirens and their combat effectiveness, which is completely out of match with the level of technology, have always been the focus of human research.

This was the case in the last world, and Wang Yu guessed that it was also the case in this world.

But that's not what he's going to worry about for the time being.

He now just wants to repair his battleship quickly.

So since the shipyard with the blessing of siren technology is so magical, then simply use it.

Under the guidance of Mio Habara and Miss Eugen, the battleship slowly sailed into the dock under Wang Yu's operation.

The dock itself is wide enough, so this can be done with careful handling.

After entering the dock, the battleship magically stopped automatically, and then the water barrier at the end of the dock closed, and the seawater in the dock began to drain out rapidly, and the battleship began to "descend" as the water surface lowered.

Eventually, the battleship touched and was fixed on a pedestal under the dock.

"We can leave the ship, and the next thing is to go to the interactive platform at the core and start scanning."

"Are you sure you don't need to remove items from the ship?" Wang Yu asked again.

"Not really."

Habara Mio said with a smile: "Don't worry, I have already carried out many repairs on my battleship, and I am already familiar with this process, so I can only say that the siren's technique is indeed amazing." ”

Wang Yu then followed her and left the Annapolis.

It was also the first time he had set foot on solid land in this world.

He glanced back at the battered battleship.

She's worked hard too, and it's time to bring her back to life.

The three of them, or two of them, came to the center of the dock.

Miss Eugen walked up to a screen in front of the core and tapped her hand on the screen several times, allowing the device to begin scanning the Annapolis.
