The underworld is huge, how big is it? No one knows, only that they are at least ten times the size of the surface together, because they have dozens of layers.

It is said that the world is square and oblique, and it is a square diamond. Originally, the world was supposed to be cropped into squares like the parchment scroll, but when the man who returned from traveling around the world in the ancient century and drew the map set the northern world to be due north, the world map was spun and tilted by 39 degrees.

It is an incredible place, it is not driven by any power engine, nor does it need the support of the continental shelf, it can be suspended in a void without the ocean; On the other hand, the ocean-going continents of the West are all wrapped in seawater, leaving no gaps at all. The rest of the continents are half wrapped in seawater, and the other half is resting on nothingness.

From a distance, the ocean area on the map seems to be in the shape of a horizontal droplet, and the round water droplets encircle the entire oceanic continent, but the Northern Celestial Universe is left alone.

The total area of the ocean and the four continents combined is the area of the first layer of the Underworld, and the average height of the top of the first layer is still up for debate.

Yes? What the? Elevation? Oh, sorry, the underground sea can't be counted as a sea. If you really want to use this unit as the benchmark horizon to calculate the ceiling height of the underground world, you can only calculate it from minus a few thousand to tens of thousands of meters.

In addition to the main continent of the ground named the mortal realm, the underground world, which is hundreds of times larger than the main continent and is desperately large, is a real hodgepodge, but because of the congenital bad environment of the underground world, most people on the ground cannot adapt to it. There are fewer people from the ground, but the people who start from the underground and think of the ground have never stopped, and the people who have been discriminated against and relegated to the underground world are all eager to return to the surface, and the original race in the underground also wants to go to the surface to see what it looks like.

But that's not all, just like the Human Alliance can only occupy the position in the north of the center of the continent, and no one can explore the vastness of the underground world, after all, this world is still full of unknown and mysterious beauty.

Huh? Why would I know? It seems to have read it from a book. But I don't think I've read a book, right? I never read a book because I was just a beggar of six or seven years old and I couldn't read.

But why do I think I've seen it? And it seems that I have seen all the words on it......

Indissoluble.

"I'll teach you how to read." Van said suddenly.

「？」 What's wrong, all of a sudden? Is it because I haven't asked questions for a long time and haven't bothered you? Although I don't know what's wrong with me, after entering the underworld, I suddenly don't have anything to ask, I just want to follow you quietly and stay by your side.

"......" Van was silent for a long time, "No, I just want to teach you."

"I find it strange that there is a period of time when I can't see what you were thinking, and when the blank period is over, you say you can't read." Van broke off a long, white bone from a huge dry bone passing by, maybe a fish bone, right? I guess so. After a pause, he wrote some characters on the ground along the way with his bones, and he pointed at the first character with the tip of his bones and asked, "Do you know this?"

I shook my head.

"What about this?"

Shake your head.

"This?"

Still shaking his head.

Now the Brahma didn't waste his tongue, and the characters pointed to the past, and I think he knew that I understood what he meant.

Most of the time has passed by a large list of characters, some of which are simple, some of which are abstract, some of which are extremely complex, and some of which seem to be written not on the ground at all, but on objects that stand up, and can be seen from many sides.

But shaking the head, shaking the head, shaking the head, shaking the head, none of them I knew—"Ah! I know that!"

I screamed excitedly before Van pointed the bone to the next character.

"Brahman, Liberian...... Lido? Van Rito?" It was as if I had just learned a language, and I pronounced it out loud to the font, each syllable was difficult, and each syllable was extremely simple. Then I wondered, "What is Van Rito?"

"Me." Brahma said.

Are you sure?! Oh, my God!

I stumbled off Van on his back, out of the illuminated area around Van and stumbled against the glowing moss of the surrounding underground specialties to find a slender pointed bone that had been broken, and ran back to rewrite it under the words of the same system.

When I finished writing, I turned back to Brahman and said, "Is it right?" I even saw my sparkling eyes through the reflection in Fan's eyes, and at the moment I was like a down-and-out puppy that had just been picked up, eager to show himself to his owner.

"It's a good imitation." Brahma touched my head, and the tip of his bone was ready to point to the next word: "What you just wrote is the lingua franca, the universal language, and at the same time the mother tongue of your human race, and the language we use to communicate and communicate now. Now let's move on."

The lingua franca is like a beginning, and I vaguely recognize several languages in the remaining characters, Sanskrit says that I recognize Titan, Dragon, and Orc, and I don't understand what he means by Titan, Dragon, and Orc, but I understand what he writes, and Titan, Dragon, and Orc are all written "Van Lido"! Can I infer from this that the remaining characters are also written "Van Lito"?

"What are these words?"

Van glanced at me, and I knew that my mind had been recognized, because he knew everything I was thinking.

Brahman started from the beginning, skipping the words I knew and clicking on them one by one: "Demons, Elves, Metal Life, Celestials, Protoss, Elementals, Demons, Sea Clans, Elves, Winged Clans, Undead Clans, and Demon Clans." The orcs didn't need words, so they didn't invent them."

Wow...... Better!

"There's so much you don't know." Brahma said.

After that, Van began to take the initiative to teach me things, whether it was literacy or code cracking, whether it was arithmetic or legendary magic, he was very careful to teach me one by one. Sometimes, on a whim, I would fall into a situation of rushing to absorb knowledge for a week; But when the Brahmans are lazy, I may not even be actively taught once a month.

Pass some peculiar underground scenes along the way:

For example, in the half-naked nascent crystal mine, the purple, green, and orange colors will be mixed into a brilliant color, which will be refracted everywhere through the luminous energy inside the largest central crystal, and the immature small crystal on the top of the inverted mine will refract these rays again, shining like stars in another world.

He jumped to the middle of the crystal cave with me in his arms, and smashed the upright crystal pillar that he was not holding in half with a single punch, and the upper part of the crystal pillar slipped and fell, and a sleek platform appeared for us to lie down and enjoy this rare beauty in this life.

But he didn't move the biggest crystal pillar, I think that's probably because the light comes from there, and without it, this place wouldn't be beautiful anymore, right?

I always felt that I had never seen such a rainbow-colored scene full of crystals, but I had no clue, and I couldn't figure out where I had seen it even if I broke my head, and I didn't have this place in my memory.

After the two of them lay down, I nestled in the crook of his arm, I was too small, in his hands like a baby, one hand gently hugged, I was his.

"You know what? No, you won't know. I used to ......."

These thirteen words will always be the opening words of his memories. Whenever he encountered a strange scene, he would lie down with me and tell me about his past, his past, from which I learned a lot, his resentment, his hatred, his innocence, his innocence, his loneliness, his loneliness......

He doesn't get bored, I don't get bored, look at the wonders and look at him, I will always listen quietly. (To be continued.) )
