Obviously, Nitro's performance in Kira's eyes is not to see the coffin and not to cry.

"Okay, so let's talk a little bit about the world we live in." Kira took a pen and paper that she had taken out of nowhere, spread them on the ground, and drew a straight line on them, "Lord, what do you look like in this picture?" ”

A blank sheet of paper with a straight line across the white paper, a very simple picture, Nitro stared at the so-called painting, and finally concluded that Kira was teasing him.

"Really? Teasing you? No kidding, I'm not as busy as you are, but I'm not that idle. At this moment, Kira seemed to have the ability to read minds, and he turned the pen in his hand and said, "If you can't see this, then what? As he spoke, he drew an inferior arc on the straight line, occupying the position of the center of the line.

"The sun?" As an old fellow with a deep understanding of nature, Nitro still saw at a glance that it seemed to be a sun.

"Good eyesight." Kira slapped the floor with her hand: "This arc is a sun, and with your discerning eyes, you can tell at a glance that it is a sun that has not yet fully risen or set. ”

Nitro gave him a blank look. "My eyesight isn't as good as you say, but if you want to tell me that the sun rises over the horizon, it doesn't mean anything. ”

What the?

"Doesn't the slow sight of the sun rising over the sea prove that the world is round...... "Uh" Kira felt that she must have been punched by the old man in front of her before, and her thinking was incoherent, and the sun rising from the sea level seemed to really not be able to prove that a planet was round, etc., how to prove it?

"Proof what?" The elder seemed to have heard something, but it seemed to him that the kid had overturned his own ideas, which was good.

Kira looked at him with a smile, and then slapped her thigh, how could I be so stupid!

"Of course, this is just a foreshadowing." Kira picked up the brush again and took a triangle shape at the previous sea level, "Has the president ever been a boat?" ”

Nitro was noncommittal.

"So what is it like when you see another ship rising from sea level on board? Can you tell us about it? ”

Nitro's expression finally changed, but he didn't say anything, waiting for Kira to continue.

"Yes, we tend to see the sails of another ship first, don't we? Then we slowly see the hull, which means that the world we live in is not a flat continent, but a curved sphere. Kira paused, he couldn't say bluntly that this was a planet Balabala, he guessed that the world is a ball, this theory that people like Nitro and V5 officials should know, but for some reason organized science popularization to the world, so as a native who doesn't know anything, it is enough for him to show his own conjecture.

"Since it is a sphere, then the world is divided into two poles, how can the whole world usher in light and darkness together!? It just means that the area we are in, the area we can explore, occupies a palm-sized part of the whole world, doesn't it? ”

"I've been to the ancient wolf mounds on that island, and the size of those wolves gives me enough guesses and data that they may not be extinct, but they live in places we can't reach." Kira took a deep breath as she spoke, and it was time to draw conclusions.

"The conclusion is, is the human world like an ant's nest in front of the whole world? Of course, maybe a little bigger. ”

At this moment, Nitro's eyes finally changed from indifference, but to thought, he knew the truth of the world that Kira said, that vast area was called by a few people - the Dark Continent.

And Nitro, as a person who has been to the Dark Continent, has a deeper understanding of what Kira said, the human world is indeed too small, an airship, a few days can shuttle back and forth, without seeing the outside world, you will never know how small human beings are.

Ant nest? That's really an apt metaphor, in Nitro's opinion, the continent occupied by humans is indeed no different from a larger ant nest, and he walked on the dark continent like an ant. It was precisely because he knew the truth that he still remembered the shock in his heart when he saw the truth, and he had no doubt that if everyone knew that they, human beings, human beings who thought they were the spirits of all things, were nothing more than pets kept in captivity by beasts in their eyes in a big place with a big palm, they would drive most ordinary people crazy and cause social riots!

Kira watched as Nitro's eyebrows furrowed and loosened, then furrowed again, over and over again. He knew that the old man was thinking about whether or not to answer his own question, and Kira waited patiently, knowing that he would know everything in the end.

"You, you're right, the world is big, bigger than you think." Nitro sighed and returned to normal, telling one of the juniors that it was okay to tell two.

"We call the area outside of the human world the Dark Continent, and the world we live in is located on the huge lake Morbius in the middle of the Dark Continent, don't get confused about how this name came about, it's obvious that this is the name set by someone." Nitro looked at Kira, who had a tangled face, and explained impatiently: "Human beings have gone to explore the Dark Continent many times, both known and unknown, but from the known human exploration activities, a total of one hundred and forty-nine times, five of them have survived and returned, a total of twenty-eight people, but only one person is still alive in the world. Nitro didn't say the man's name, and Kira subconsciously thought it was an inconsequential fellow.

"You also asked about the figures of those giant wolf clans before, I can tell you, old man, I also went to the Dark Continent when I was young, and in my opinion, the giant wolves thirty or forty meters tall belong to the middle class there, there are many more than their huge species."

"As for why those wolves left here in the first place, maybe it was because of some kind of rule."

"Rules?" Kira asked.

"Well, everyone who wants to go to the Dark Continent has to go through a group of people called Gatekeepers, some people say that they are Warcraft, but I don't think so, but there is no doubt that it is the Gatekeepers who make the human world stable today, and their mystery has never been removed.

Now that V5 is in control, no one can explore the Dark Continent at will, because in the past exploration, someone brought a disaster that humans can't understand from there! So for the safety of humanity, they still made a new pact even though they already had a gatekeeper!
