The kingdom of Mistra, the land of the merfolk, has far more underwater navigation technology than humans, but it still adheres to the imperial tyranny of the king who decides everything.

Izuki has never understood that the feudal imperial system, as a ruling system that has been eliminated by most human beings, undoubtedly shows that it is not advanced and excellent enough. Why do so many civilizations still maintain the rule of the "dictatorship of kings"? According to Nobita, even among the seven elder civilizations of the Cosmos, two civilizations are still using backward imperial autocracy. Obviously, it is already a kind of civilization, and it is incredible that a great existence that can shake the circle three times by stomping in the pan-civilization circle is still using imperial autocracy. He once asked Nobita this question, but what he got was a wry smile from the latter, as well as a meaningful answer - "Xiaoshan, you are right, but you made a mistake".

"What is suitable for mankind is not necessarily suitable for other races; In the same way, what is suitable for other races is not necessarily suitable for human beings. Methods and experience are not universal in all situations. ”

To be honest, he didn't understand what it meant at the time...... Subconsciously, Izuki felt that the intelligent race and humans were similar, and the way of thinking was not much different.

And at this moment, sitting on the "welcome boat" with the characteristics of the mermaid clan, watching this large-scale underwater city flash in front of him like a glimpse of light, Izuki suddenly had a flash of inspiration, and understood the deep meaning of Nobita's words. He couldn't help but feel that Nobita was actually very smart and sharp, and he was no worse than himself in terms of thinking...... Before the age of ten, his poor grades were due to his laziness and lack of motivation; After the age of ten, his grades were poor because the focus of his life was on other things.

Far away, take the mermaid clan as an example.

A race that lives at the bottom of the sea, with inexhaustible resources, and no neighbors to compete with them. Without an enemy, it would not have been possible for humans to go down to the bottom of the sea so deep to harass them, and to develop so quietly and peacefully...... They may think it's good that technology has advanced to a certain stage, and the political system hasn't changed at all. From the inside out, the thinking mode of the merfolk is different from that of humans, and if they have to say it, their old enemy, the strange fish clan, is more similar to humans.

Unexpectedly, after entering the territory of the Mistra Kingdom, the welcome ship was separated from the army escorting it. There was no grand welcome waiting for the shirts, on the contrary, the whole kingdom was peaceful, looking down through the car window, the city was still full of traffic and peaceful. Most of the citizens didn't even know that there was a land-based man flying over their heads in a welcome boat, and it was business as usual, without the slightest excitement, and everyone was supposed to do what they were supposed to do.

This makes Izuki feel a profound cultural difference - at least on the earth, if a major government sends dignitaries to visit Shinjuku, Japan, as long as they walk the streets that day, the area will be absolutely clean, and there will be government agencies to contact the local underworld groups in advance, asking them to take care of their little brother on the day of the visit and not come out to make trouble. In addition, at least a dozen bodyguards must be arranged in each building to keep an eye on the whereabouts of the bigwigs throughout the whole process, so as not to have any accidents on the way and cause an international scandal in their own country.

And in the mermaid kingdom under the sea, there does not seem to be such a set of concepts of "diplomacy". I can almost be regarded as an alien to the mermaid clan, an alien came to visit, but the city was still so calm, there was not even a movement......

The golden airship swung around the city a few times, and led the wooden shirt straight into a luxurious royal palace.

Looking at this temple comparable to the Abu Dhabi Mosque glittering in the light, Izuki couldn't help but sigh that the resources under the sea are really abundant...... The palace smells of luxury from top to bottom, and the stone is considered the most inferior building material, but even so, the rough stones have been polished with such exquisite craftsmanship that they are barely visible from a distance. In addition to the aftermath, the Mistra Palace can be said to be directly piled up with a variety of minerals, and the precious gems are processed into bricks and ornaments with great care, and stacked on top of each other in an astonishing amount, which inevitably makes people feel heartache and cry out for the destruction of heavenly objects.

"However, their understanding of 'luxury' may not be the same as that of humans, so there may be no need to be ......unbalanced for them," the keen-eyed Izuki immediately thought, "In the eyes of the mermaids, maybe these precious minerals are just beautiful stones." ”

Turning left and right, they walked through the palatial cloister and into a spacious library.

Yes, the library...... A place dedicated to books.

The first time I saw that there was a library here, my jaw was about to fall off. Because of the [Adaptation Light], he could still see clearly at the bottom of the sea, so he didn't realize that something was wrong at the first time...... It wasn't until a string of bubbles came out of his nose that he realized it was the bottom of the sea, and there was absolutely water all around! Is there a library in this situation? What's the state of your book? Carved in stone? Even the Mesopotamian plain characters on the stone tablets will quickly blur when soaked in water all day long, right?! With so much paper, not to mention the problem of water pressure, just soaking will turn into pulp, right?

Sophia led him to a long table, pulled out two soft-cushioned benches framed in granite, and motioned for him to sit down.

As if reading the confusion in his eyes, she smiled and waved her hand, explaining, "The components of these books are called 'sedges', and they are unique to the merfolk as a way of storing them. ”

"Won't it rot?"

"No, it won't."

"It's incredible...... Izuki sighed, "There are scientists in the world on earth who claim to have made waterproof paper, but if you throw it to the bottom of the sea, it is estimated that it will be reimbursed." If it doesn't break, it's certainly not made of paper. ”

"You may not know that there are no continents in our home planet, Blue Mercury. If the merfolk want to store information in the water for a long time, they naturally have to develop corresponding technologies. We've long been used to doing everything in the water. Sophia explained, "This is the library of Mistra Palace, which contains 509,811 books, which record all the stories of our journey from Blue Mercury to Earth, and then to Earth for 5,000 years. ”

"Eh......" Out of the wooden shirt felt the kindness coming from Sophia, and the tension subsided little by little, and he looked around a little relaxed.

Sure enough, the library was a separate building with a sapphire dome and dome bottom. Having learned a little bit about architectural appreciation, Izuki still likes the round floor—the design is full of spirituality. The entire library is round, with huge three-story shelves showing a pomegranate-like dark red color, which is arranged in a circular arc, like a solid wall, enclosing the square table in the center. Under the overlook of countless books, Izuki gave birth to a sense of awe of "born small", and felt fulfilled by this sense of awe.

That's not the point.

There is no third person in the huge library.

"Your Majesty, is there no one else here?" Izuki Kazumi was a little strange about this, "Building an alliance is a big deal after all, and you're sure you don't need someone like the cabinet to ......"

"No, you don't." Sophia shook her head, her long water-blue hair swaying like waves around her waist, "Actually, there is no cabinet either. I can take responsibility for my kingdom, and joining the Olive Leaf Alliance will be more good than bad for the merfolk...... Or rather, I see little to no harm at the moment. Unlike humans, the merfolk do not assess the future by mathematical analysis, but by prophecy - using a magical method inherited from Blue Mercury may be a bit difficult for you humans to understand. All in all, the outcome of the prophecy was the same as I thought, a bright light, and from Nobita's voice ringing in my head, I had actually made a decision. ”

"The kingdom of Mistra will join the Alliance of Olive Leaves and make an oath."

"This ......" Izuki froze suddenly, and he didn't know whether he was relieved or regretful. After doing it for a long time, Her Majesty the Queen already had a fixed number in his heart, and it was the same whether he came or not. Inexplicably, there is a sense of loss like "after reviewing for a long time, I found that the exam was cancelled......

"I'm sorry for you to make a special trip." Sophia smiled at him kindly, "Actually, it doesn't matter if you don't have to come here, I will trust Nobita 100% in what he says." ”

"You trust him so much?" Izuki said curiously, "What if he ...... After ten years, what has changed? ”

"Has he changed?"

"How so...... Change is change, because a little bit of something happened to him that made him not so ...... Immature? When doing things, they also use some methods that they have not considered before. "Izuki carefully searched for words to describe Nobita's changes, "But in the end, his heart has not changed, and there are still many people who will spontaneously gather around him, be infected by his ideas, and join him to do things." ”

"That's fine." Sophia smiled softly, "Mr. Izuki, you should take it as if you were here for a sightseeing tour of the merfolk clan, have a good time for a while, and taste the specialties here...... Such opportunities don't come often for humans, right? ”

"I'd love to be here so leisurely, but I'm sorry...... Since His Majesty has decided to join the Olive Leaf Alliance, he must send a representative to join me at the Alliance's first base for the inauguration ceremony. "The Congo Basin, the Smoke Ghost Forest." Nobita said the alliance's No. 1 base station would be built on a foggy rock. ”

"Can this guy already say such a godly thing......" Sophia squinted her eyes and complained, "If I'm not mistaken, it looks like there are similar sentences in the human Bible, right?" ”

"Uh...... Hawkers, it's also normal, Nobita has been more depressed over the years, and he has just improved recently, and he just happened to be at this age again. Izuki scratched his head awkwardly, it was obvious that Nobita's second illness had attacked, but when he repeated his words, the embarrassed one was himself!

Sophia covered her face with her sleeve and laughed softly, as crisp and pleasant as an afternoon wind chime.

For most of the next day, she gave up her wooden shirt and retold Nobita's experience in the past ten years.
