Annapolis began a full-scale restoration in the dockyard.

Wang Yu naturally entered a period of idleness.

Let's go out, it's too cold outside, so I'll just stay in the shipyard all the time.

He asked Mio Hahara for some books about this world, thinking that being idle is also idle, so it is better to take this opportunity to make up for the common sense of this world, so that he can be more confident when talking to people in the future.

As a result, I don't know this, but I don't know about it, and I found that the history of this world is really complicated.

Mio Habara has always felt that he is a "ghost" from the last civilization that has survived to this day, so his focus is also on the last civilization.

Indeed, as the girl said, there was another advanced civilization on this planet.

It is a global civilization that is incomparably advanced in the fields of science and technology, culture, politics, and economy.

The era in which that civilization was located at that time was called the first generation of the planet.

The first generation of civilization was undoubtedly powerful.

They have solved the energy crisis that every civilization will face with miraculous means, solved complex social contradictions with a mature political system, and provided every member with a ray of hope to move forward with the broad development prospects of the universe.

According to the limited information, at that time, that civilization had already set foot in the corners of the planet, and all the secrets contained in the planet were revealed to the world, and they were ready to start taking steps towards the distant starry sky.

According to normal logic, this civilization should use the beginning of prosperity and unification.

They will travel through the stars for the next hundred years and continue to develop.

However, things are unpredictable.

Every civilization dies for a variety of reasons before moving into the future.

Unfortunately, this super civilization is also one of them.

There is not much recorded in this section, but judging from the only information about the ruins, the siren crisis broke out just as the super civilization was just about to start its space voyage.

The sirens seem to think that this civilization is a bit too urbanized.

As a result, this powerful civilization was destroyed in a short period of time.

There is no more detailed account of this part, but it is clear from the few words that the factor that led to the demise of this civilization was the Siren crisis, which the civilization of the time seemed to refer to as "the judge" in addition to the "siren".

Through various means, the sirens destroyed this civilization and destroyed almost all of life.

The traces left by civilization on this planet were erased by the sirens

And the few that remain have gradually decayed over time.

As time passed, new life began to evolve again on the planet.

As with normal development, humans began to walk upright, and gradually a new human civilization was formed.

Since the sirens erased most of the traces left by the first generation of civilizations, this new civilization did not inherit any legacy, but like a normally evolved civilization, it began with the cradle of the first life underwater and continued to ......

I'm sorry, but it's on the set.

In short, many more years have passed, and human civilization has once again become glorious on this planet.

This is the current second generation.

Through archaeology, the current human civilization has discovered a very small number of relics that have survived to this day, and it has been determined that there was an era of civilization before them, but because there are too few things left, the second generation of people do not know much about what the first generation is like, and can only summarize the knowledge content about the first generation from limited information.

Wang Yu closed the book and couldn't help but think in his heart.

This world is obviously completely different from the last one.

At least Wang Yu had never heard of the so-called distinction between the first civilization and the second civilization in the previous world.

But it's two completely different worlds, but there is the same siren crisis.

What kind of existence is the siren?

Wang Yu glanced at the battleship that was slowly being repaired little by little in the dock not far away.

When he learns that the Sirens have destroyed a super civilization, he can't help but feel a little unreal about the fact that he once operated artillery warships and Siren warships.

Why would a siren with such a high technology be willing to engage in such a rudimentary battle with human civilization?

What's the plan behind the sirens?

What does their appearance really mean?

If humanity is really forced to abandon the sea, what will the Sirens do to continue attacking?

In the past few days, Wang Yu's mind has been hovering around these questions.

In fact, this kind of problem is far from the level that an ordinary individual should think about.

Even if he tried his best to guess, he couldn't come up with a reason.

On the contrary, the more he thought about it, the more he felt that the sirens might have some ulterior conspiracy.

These conspiracies were woven into a web that gave him a feeling of being out of breath.

Maybe it's because he really doesn't have anything else to worry about these days, or maybe it's because he has personally experienced such a big thing as a time travel, or maybe it's because he has learned something beyond his own cognitive ability, which makes him think about it.

There are even some unfounded worries.

In short, if he continues to think like this, sooner or later he will have a mental breakdown.

So in order to prevent Wang Yu from continuing to be an otaku in this shipyard, on a warm winter morning, Mio Hahara came to this siren shipyard.

"Long time no see." She greeted Wang Yu with a smile.

"It didn't take long."

"It's been a month since you started repairing the battleship, and it seems that you have been immersed in the ocean of knowledge."

She saw several books piled up on the table and the notebook full of contents spread out in front of Wang Yu.

"Did time pass so quickly?"

Wang Yu stood up, he paid attention to hygiene, so even if he stayed in this shipyard all the time, there was no situation where the whole person became sloppy, and the only trace may be a faint tiredness on his face.

The smile on Mio Hahara's face was warm, dispelling a trace of Wang Yu's tiredness.

She said to Wang Yu: "I came today to ask if you are interested in going with me to the headquarters in the United Port Area?" ”

Wang Yu recalled that there were several port areas in this large area where Habara Mio was located, and they belonged to a joint port area set up by the Navy Administration, and the joint port headquarters that the girl was talking about at this time was a small city about two hundred nautical miles away from Habara Mio.

"Why are you going there all of a sudden?" Wang Yu asked.

"It's about to enter the depths of winter, and according to the convention, the port area will go to the headquarters at this time to make a big purchase before the Chinese New Year." Mio Habara told Wang Yu about her plan: "By the way, go to the Commander Trading Center to see if there are any important supplies I need." ”

Wang Yu understood that the port area of Habara Mio was relatively remote, not only did the materials for maintaining the port area need to be transferred from the headquarters of the United Port Area, but even some daily necessities needed to be purchased there according to the time.

But what is the Commander Trading Center?

"The trading center is a place for exchanging materials planned by the Navy General Administration and opened by special commanders." Mio Habara held up a finger: "The trading currency is the 'military merit' obtained by the commander after performing his usual missions, which can be exchanged for some rare resources; ”

"So that's the case...... Wang Yu nodded: "Then why did you come to invite me?" ”

"Maybe you can find something you're looking for, like a welcome gift for your ship's future consciousness."

Mio Habara made a little joke.

Then she said solemnly: "However, I am a little embarrassed that you have been staying in this shipyard these days, this is not qualified hospitality—and I think you should try to have more contact with our time, communicate with more people, and see our development with your own eyes, maybe it can bring you a different experience." ”

Wang Yu pondered for a moment.

Instead of thinking about something fake and empty in this shipyard, it's better to look at different corners of the world with your own eyes, as Mio Hahara said.

So he couldn't help but smile a little.

"Maybe you're right, I've been bored here long enough, and it doesn't hurt to go out for a walk.

"So, when are we leaving?"
