Rewind the clock to a day ago. In one of the towers at the base of the horizon.

Nobita dispatched any for the first time like a novice village grandfather, and with a tone of 12 points of calmness, he handed out the props he had taken out of his pocket to everyone, saying things like "it's not a big deal" and "this mission is extremely simple". At first, I was secretly relieved, but the next second I heard Nobita say that he was going to set up a behemoth called the "Olive Leaf Alliance", and the members of the organization were involved in five mysterious countries that had not yet been discovered by humans, mainly for the purpose of exchanging developed technology and culture between civilizations...... Once completed, the potential significance for the future of the planet is too great to be overstated.

He was stupid at the time...... Is this what he calls the "simple mode"? This kind of properness will have an impact on the whole earth, and the big historical event is no less than the Industrial Revolution or World War II, and he handed it over to four high school students so lightly that he couldn't figure out whether Nobita was too confident in himself or too arrogant.

But on second thought, the things researched in this base alone seem to be enough to subvert the current earth civilization. Compare with the second base, unite the lost country, and form a civilization or something...... It really seems to be just pediatrics.

However, what surprised him even more was still to come: after Nobita took out the props, Fat Tiger, Xiaofu, and Shizuka didn't say a word, but each chose in silence, took some of the props on the table, and then turned around and left. It seems that they are already familiar with the use of these props and precautions, and they don't even need Nobita to explain much, so they start acting on their own...... Any of the buildings in the base of the horizon contain "portable hotels" with countless built-in rooms, ensuring that you have a place to rest wherever you go.

The young man probably found a random room to prepare, because according to Nobita, after six hours, Yu Feiyan will arrange a group teleportation. And once this group teleportation is activated, no matter where you are, you will be shrouded by a pillar of light falling from the sky, and then you will shake your eyes twice, and your body will cross several large plates to where you should go.

Izuki has an inexplicable feeling of being left behind - as a "genius", he has always been at the front, and now this feeling of companions finding things to do and being overwhelmed is very rare.

It turns out that loneliness and fear are like this......

……

"Shirts? Are you nervous? Apparently Nobita also noticed the mood changes in Izuki, and he was an expert at dealing with such emotions - and interestingly, before the age of ten, Nobita was basically the one who fell behind every time, and naturally had his own set of ideas on how to adjust his mentality...... At this time, when he was a child, he actually wanted to use this set to comfort the best in his childhood memories.

"Don't be nervous, there's nothing to be afraid of, just think about it, how could I push you into the fire pit?" Nobita smiled with relief, "We have all visited, seen, and understood these five civilizations used to form alliances before...... There may have been some conflicts with the humans on earth before, but the misunderstandings have also been resolved. Now they can all be classified as 'well-intentioned civilizations'. These five civilizations have a history of contact with us, and with me in the middle, the covenant is easy to make......

I can assure you that the merfolk are indeed a good bunch of people, and the good ones are unexpected...... You don't have to worry about saying the wrong word or making the wrong gesture and getting tied up and hacked to death. They are also a group of poor people, who have to flee because they are hunted down on their home planet because they hold a strange treasure. After coming to Earth, he has been hiding at the bottom of the sea without showing up, and it took several twists and turns to defeat his old enemy. ”

"Thank you." Izuki smiled a little reluctantly, "It's just me...... Nobita, for as long as I can remember, the farthest place I've ever been out of my home was Sapporo, and I went there to participate in the competition on behalf of the school, and the school chartered a car for us, and this is the farthest I can remember. Now, if you suddenly ask me to go down to the lowest part of the deep sea alone, to a place where there is no light, negotiate with a group of legless people with wagging fish tails, and persuade them to join an alliance of elves, dinosaurs, and erect dogs, I ...... a little."

“…… Having trouble adapting? ”

The biggest advantage of Izuki is honesty, just like now, he doesn't keep doubts in his heart, but simply admits that "it's not a problem that is difficult to adapt." Honestly, I didn't understand what you were just saying, I ...... It's not like Xiaofu and Fat Tiger, who have experienced those things with you. I haven't been to the Congo Basin, I've never been to the Bermuda Triangle, I've never been to the crevices between the earth's crust and the mantle, and I don't understand most of what you're talking about. ”

"But you're here now, by my side." Nobita replied lightly, paused, and seemed to have something else in the semantics, so he was stunned.

……

"Xiaoshan, are you my friend?"

"Of course!"

"Why join me?"

"I join you based on my own judgment: I think what you are doing, your ideas, will be beneficial to humanity in the future."

"Then be brave." Nobita looked him straight in the eye and gazed at him with the sincerity possible, "I need you now. ”

……

After that, Nobita taught himself how to use these items and what to focus on when negotiating with the mermaids. The flashlight that looks like a pistol can emit a magical light, and after irradiation, humans can adapt to any harsh environment for 24 hours, even if they go down to the deep sea, they will not be flattened by water pressure; The box of things like hand cream is called "deep sea cream", and it will have the same effect when applied to the body; Two small, short straws are inserted into the nostrils to breathe in the oxygen in the water......

Six hours later, as promised, Izuki came to the bottom of the sea.

He didn't know exactly what sea area it was, and he didn't ask - since joining Nobita's camp, he had chosen to trust Nobita 100%, so he wouldn't ask about those superfluous things. The bottom of the sea is brighter than I imagined, and I guess this is also the effect of shining on the [Adaptation Light]. Even if the real deep sea is dark, you can see underwater without any difference from land.

A large group of people gathered around the border, seemingly waiting for him to arrive.

The fact that the lower half of their bodies are indeed human legs rather than fish tails also surprised the wooden shirts...... Before leaving, Nobita explained to him various characteristics of the mermaids, one of which is that for convenience, they only take the form of fish tails when they need to travel long distances under the sea, and they can generally maintain human legs. But in any case, it always makes people shudder to see a group of guys who are no different from humans standing at the bottom of the deep sea......

Most of the soldiers are wearing armor, and the style is like a medieval warrior holding a high-tech firearm from the future world, full of a sense of disobedience. Several fish-shaped airships are suspended in the water, almost the size of a juvenile sperm whale, which is quite intimidating. But the soldiers did not turn their guns at themselves...... The curiosity in their eyes was greater than the hostility, and a few of them even deliberately stretched their necks to see what they looked like as "people on the ground".

If you look at the water pressure, you can see that it is not often visited......

Queen Sophia Mistra stood at the front of the line. The growth process of the merfolk seems to be very different from that of humans, and ten years later, she is still about the same height as before, and she has not grown much. The long aqua blue hair floated behind his head, combed into two sturdy long ponytails, and a gold headdress inlaid with rubies was embedded in the hair, symbolizing the supreme authority of the mermaid royal family. Izuki couldn't recognize the material of the clothes she was wearing, and in the deep darkness, the fabric that made up her clothes showed no signs of "floating", clinging to her body, with an ancient pattern of a pentagram printed on it.

Under the navy blue background, a golden pentagram is printed on Sophia's chest, and the perimeter is lined with a circle of ocean blue patterns, faintly exuding a glass-like brilliance. Ten years of rule had obviously made her grow a lot, and the last bit of childishness that belonged to a young girl had completely faded from her azure eyes, and staring into these deep eyes, she could only see responsibility and firmness.

Izuki took a deep breath and spat out a series of bubbles like a fish.

He had studied the ancient symbols and the meanings of these symbols derived from modern religions. Among them, the "pentagram" is a particularly ancient type, even older than the time of Solomon and David...... The origin of the pentagram dates back to that time in matriarchal societies and symbolizes the worship of the "goddess", which is still used by some ancient sects to this day. Later, with the rise of Catholicism, the Holy See, in order to eradicate other faiths, denigrated this original holy symbol, turning it upside down and becoming the embodiment of Satan.

What a coincidence, Sophia is a queen. And according to Nobita, the hero who drew the sword in the history of the mermaid clan is also a woman!

So, here's the problem.

Nobita once said that the merfolk are not the native race of the earth, they come from a place called "Blue Mercury". Why do they have the same symbolic worship as the earthlings? Is it a coincidence? A planet far away in the constellation Auriga, separated from the Earth by an unknown distance, and a civilization that lives underwater...... How coincidentally they chose the same symbols as human beings for worship?

If, if not......

Does it mean that the pentagram is a universal symbol in the entire universe, or in most civilizations? (Through Nobita's description of the Cosmos, Izuki judged that there are a large number of civilizations in the universe) The primitive things it represents, whether on Earth or on Blue Mercury, are all connected?

Out of the wood shirt is out of the wood shirt in the end, the huge knowledge gives him plenty of room to think, just by seeing a symbol, his sensitive brain began to work rapidly. In a trance, his expression became more and more astonished, as if he had seen the barren and dark universe, the magnificent nebula, and some unknown secrets hidden in the depths of the universe through this pentagram...... What does it mean to be culturally universal? He didn't understand for a moment, or maybe the discovery was too significant, and in terms of results, it could mean everything.

In contrast, the Olive Leaf Alliance may be less important.

Be sure to let Nobita know about it!

……

"Mr. Izuki?"

"Your Majesty, I beg your pardon, it is the first time for me to enter such a deep seabed, and I am a little uncomfortable." Izuki quickly figured out the current situation - hundreds of people, even the queen of the mermaid clan came out to greet him in person, and he couldn't say anything in a daze, "Now that I've adjusted, there's no problem at all." ”

"That's good." Sophia nodded slightly, "Nobita told me you were coming...... In that case, please get on board. ”
