Between the earth's crust and the mantle, there is actually a huge layer of cavities.

To humans, the space is vast, but useless. The reason for this is that human beings are an extremely picky race about their living environment, imagine that you live in an underground world without sunlight, drinking underground water, eating food with very little variety of food, and there are only a few kinds of meat turned over and over, and there is no fish. When I look up every day, I don't see the endless sky, but a huge dome covering overhead—the crust of the earth. Although the distance between the earth's crust and the mantle is several thousand meters, it is a high wall after all. Every morning, when I wake up, I see an endless dome hanging there that stretches for thousands of kilometers, and I have to be claustrophobic.

For humans, mineral deposits buried in the earth's crust are even more attractive...... Oil, iron, all kinds of rare jewelry, anything that can be sold for money, it is a good thing. As for the huge void between the earth's crust and the mantle, at the current level of human beings, it is really powerless to explore it all. First, there is no safe environment under the earth's crust, you can go with two hiking shoes and a hiking bag on your back, you have to invest huge material resources and technological products, at least you have to dig a hole with an excavator to drill down, right? Second, it seems a bit silly to spend so much effort to explore a hollow...... On the contrary, some people have the whimsical idea to transform the hollow beneath the earth's crust into a prison, so that the harsh natural environment can bring deep self-reflection to the prisoners.

But then I thought about it, spending so much money to build a prison is really a problem in the brain.

So they were destined to find out that there were other intelligent beings beneath the earth's crust.

The underworld corresponds to the Asian continent. Dragon Kingdom.

A maverick team paced slowly in the "holy places" of the kingdom, walking here and there, and was not in a hurry, like a group of old cadres who were touring the mountains and rivers. The warm wind unique to the underground blows the tall vegetation in the holy place, most of which are prehistoric ferns, and the wide and fat leaves flutter in the wind, which is also comfortable. Interestingly, there were no half tourists in the 300-square-meter holy place today, and it was so clean that the team was walking around in it, as if they were shooting some wonderful exterior scenes. Standing in the outer circle of the Holy Land stood a column of heavily armed and armored soldiers, standing straight, staring intently at the group of people walking in the Holy Land, especially the human in the lead.

It seemed that if he showed the slightest abnormality, a large group of soldiers would pop up in any corner, raise their spears and stab him to death.

However, even though he was stared at by so many pairs of murderous eyes, the little man still seemed very calm, his speech and demeanor were normal, and his voice could not hear the slightest trembling. He was the first to walk with great style, and showed a proper curiosity about any monumental structure in the Holy Land, and consulted it, but also clicked on it so as not to disgust others.

But...... It's no wonder that the soldiers put on such a big show.

The man was followed by a total of four "men", all of whom walked unhurriedly according to his pace: the most high-ranking French king in the kingdom of the underworld, the legionnaire who commanded all the armies of the underworld, the chief priest who held power, and the old acquaintance from his last adventure, the knight Bach. Time flies, and these cold-blooded animals (literally) don't seem to have changed much, and they can't tell whether they are old or not. In Xiaofu's memory, this is the peak of power in the underground world, and if you use the analogy of the official position in the human world, it is equivalent to the prime minister and the two most powerful members of the parliament walking with him, which is not something ordinary people can have.

His Majesty's clothing is the most solemn, and the skin of the half-dragon people is different from that of humans, it is relatively hard, and naturally it does not feel the comfort of soft materials. So it's not so much that he's wearing clothes, it's more like getting the cloth right on his body...... The cloth on His Holiness alone had three different colors, a golden dragon's eye, a red comet, and a blue dragon sanctuary. These three motifs are combined in an extremely beautiful gesture to sum up all the history of the Augustan dynasty underground.

The chief priest was a little inferior, he wore the same coarse cloth, and only one color—a dark gray like embers. From top to bottom, the only bright color is the necklace he wears on his chest, in the shape of a dragon's tooth, the color of red iron, which is said to have been taken from the meteorite that exterminated the dinosaurs after he took a time machine to the "Holy War...... For the half-dragons, this necklace has the terrible meaning of the destruction of the country and the species, and reminds them how lucky they are to have the opportunity to hide underground and survive.

The Legion Commander and Bach Knight Commander were dressed as soldiers, heavily armored by their sides, and wore a half-masked helmet. Bach was a little more slender, and the Legion Commander was a burly man, standing there like a small raised mound. Half-dragon people are generally better than human physical fitness, generally two meters tall, with a thin layer of scales on their skin, and ordinary half-dragon residents can knock a human out with a single fist. After all, the basis of evolution is different, and there is a gap between apes and dinosaurs...... At this moment, the two Bach Legion Commanders accompanied the left and right, and the huge shadow of the half-dragon man was projected down, which was able to completely block the little man.

The five of them stopped and stopped, and the atmosphere was quite harmonious.

……

Unlike Fat Tiger, Guchuan Xiaofu has a treacherous and cunning face, and at first glance, you will feel that this kid has nothing good in his heart. But after getting along for a long time, the husband can always use an appropriate attitude to narrow the distance between you, and use light-hearted jokes to relieve the awkward and tense atmosphere, so that your heart will decrease little by little, and produce the illusion that he is a good fellow.

In fact, your first impression of him is the most correct.

He doesn't like to talk about things in formal settings, and in his experience, the more formal the occasion, the harder things will be. Because everyone knows that this is a serious negotiation, and the rules and regulations are very clear, it is very difficult for them to use deception...... But if at the wine table or dinner, everyone inserts two serious sentences into the eight gossip, and it is difficult to distinguish the true from the false. What the husband is best at is to pop out of his mouth a lie that is sweeter than honey, and gently persuade others to swallow it voluntarily with a slightly drunken wine. And often after others are deceived by him, they will still think of his goodness and think that he is thinking about himself.

It's the same now...... The young man didn't need to go out of his way to the Olive Leaf Alliance, he only briefly mentioned a general concept, and began to talk to Bach about the maintenance of fern rhizomes and the unique climate of the underground. Due to the large number of books he has read, Xiaofu is actually not inferior to the wooden shirt in terms of the amount of knowledge reserve, but they are not professional knowledge, and they are limited to being able to pick up various topics when chatting. At this point, this miscellaneous knowledge reserve comes in handy.

Bach didn't want to talk to him about this, but he couldn't help it, because he had something to do with the young man...... When the husband got lost in the underground world, it was Bach who took him to the underground kingdom below the Asian continent, taking care of his food, clothing and daily life along the way, and he was half an acquaintance.

Chatting and chatting, seeing that the looks of the king and the commander of the army were a little impatient, the little man knew that the time had come to close the net - under the premise that the whole thing was beneficial to the other party, if you said all the benefits at once, they might still wonder if you were okay or not. It is necessary to start with a beginning, and wait for them to realize that this is a good thing, so that the negotiations can proceed relatively smoothly.

Although his party was worshipped as gods by the "Augustan Dynasty" in the underworld, the little man did not get carried away because of this, and really spoke to them in a commanding tone. (The creators of the underworld are the Doraemon Five, who travel back in time to the mass extinction of dinosaurs billions of years ago and help a group of dinosaurs hide in the underworld.) There, these dinosaurs gradually evolved, with the most intelligent of them evolving into "half-dragons", developing the concept of tribes and kingdoms that eventually ruled the underworld)

It's better to be on the altar for something like a god to be popular.

When you step down from the altar and point fingers at the rulers, they may not accept you, but hold a grudge against you.

“…… That's all for the time being, Bach, thanks for answering these questions for me. The young man said casually, "Gentlemen, I have come all the way here, in fact, I have something more important to discuss with you. ”

As soon as these words came out, Bach, who was still cooperating with him reluctantly answering, immediately paused, took a few steps back with great interest, and gave up the conversation space to his three top bosses. The three most prominent rulers of the Underground Kingdom stopped at the same time, their long necks bent slightly like snakes in the Half-Dragons—a gesture that showed they were listening. His Majesty looked at him directly, and did not take the initiative to speak, just waiting for his next words.

"I've already said what we're going to do, and I hope you all remember." He paused slightly, as if to give these people enough time to react, "It's actually very simple, I believe that after the digestion just now, you have sorted out the stakes. ”

"Alignment, or rather, merger, right?" His Holiness's voice was deep and deep, fitting his age, giving him the impression of wisdom that belonged to an old man, "In addition to humans and half-dragons, there are many other races in this world. You want us to merge with them and form an alliance. ”

"A simple merger is not enough to summarize this great plan, to put it bluntly, the essence of Nobita's play is not to let you add one equals two, but to make one plus one greater than two...... In order to do that, you have to learn to share. The husband made a gesture to cut the cake and said in an almost exaggerated tone, "Share, share everything you have." Everything about you is completely new to another civilization, and everything about theirs is also new to you. From such a vast body of knowledge, you can pick out those that are good for you, and they can pick out what is good for them...... Taking what each needs and carrying out exchanges and cooperation in various fields is the original intention of the Olive Leaf Alliance. ”
