"For 220,000 years, the rock has not been able to break?" Jiang Hao was a little unconvinced.

"That's right, the underworld is still only 10 floors, and the tunnels and structures are basically the same." The elder replied.

"I feel that there is a change, just now everyone has also seen the holograms of the underground world 220,000 years ago, those buildings are biased towards mechanical civilization, there are roads, cars, flying machines, etc. And now this island-like land has a bit of a paradise feeling. On the east side of this land is a cliff, and that cliff was not carved out by you? Could it have been chiseled in 220,000 years? ”

"You ignored what I just said, and I said that the situation is basically maintained. Basically, not all. Not everywhere the rocks are strong, it's just that the foundation stones become strong. ”

The elder then came to a certain part of the room, and he tapped it with his hand, and some buttons appeared in the air. The elder clicked, and a slice of the underworld was displayed in front of the room.

"This is a slice of the underworld, you see, there are 10 floors, and each layer is separated by thick rocks, and those are the so-called cornerstones, and these cornerstones are unshakable. Look at the entire outskirts of the underworld, and the rocks there are also extremely hard. To sum up, the overall structure of the underworld is dead, and only partial changes can be made. ”

"In other words, it's the cornerstones that isolate the entire underworld." Tianpeng said.

"That's right, human beings can no longer expand the underground world as they want, and they can't return to the surface, so they are locked up in the underground world for a full 220,000 years." The elder replied.

Li Ming remembered that before, he threw a punch at a rock wall with all his strength, but the rock wall was not damaged at all, and his hand was shaken to the core, which means that those rocks are the so-called cornerstones.

"If the Underworld is cut off, how did we get here?" Jiang Hao asked.

"It's hard to explain, and we don't know. But maybe there was a change somewhere, and then you were lucky enough to pass the cornerstone and make it to the underworld. ”

"Impossible, 220,000 times, you didn't encounter this kind of luck, and we ran into it. What's even more exaggerated is that Jiang Wei also encountered it. Twice in a row have encountered this coincidence, and in the space of two months? Jiang Hao thought it was incredible.

"It's also a question that we haven't been able to figure out. Over the years, we've often sent people to search, but we just couldn't find a way to the surface, but you did come in, and it's really incredible. ”

"Could it be that the acid of the construction ants dissolved the cornerstone and opened the road?" Tianpeng muttered to himself.

"Construction ants? What is that? The elder was shocked.

"It's giant ants, about half the size of an adult, that spit acid and melt solid rocks. They start at the surface and dig all the way into the ground, and they build nests, and even some earthen structures, etc. Tianpeng explained.

"Construction ants? Although there are many species of giant ants in our underworld, we have never heard of construction ants. Do they spit out so much acid? The elder wondered.

"Maybe not, because the rocks near the surface aren't really strong, and I can blow them with a single punch."

"Can you describe what the construction ants look like?" The elder asked.

"It's an ant, it's just a big ant."

"Is there anything special? Like what color? ”

"Brown-black." Tianpeng replied.

Brown-black? Li Ming, Jiang Hao, Reverse Scale and the others suddenly became alert, and they thought to themselves: The construction ants are obviously gray, and the battle ants are brown and black, why does Tianpeng want to lie? Doesn't Tianpeng want the people of the underground to return to the surface?

Everyone has a lot of questions in their hearts, but no one dares to say more at the moment, they plan to discuss this matter with Tianpeng behind their backs.

But everyone was worried about Jiang Wei, because Jiang Wei had been staring at Tianpeng now, and there was a little doubt in her two big eyes. In fact, Jiang Wei has also seen construction ants, they are all gray.

Reverse Scale and Jiang Hao are very worried that the young and innocent Xiao Jiang Wei will suddenly tell the truth, if so, the situation will become very bad.

However, Li Ming behaved calmly, and she seemed to be sure that Jiang Wei would not be stupid enough to say it.

In fact, Jiang Wei did not say it, her expression became very normal, and there was no flaw at all.

As early as when Li Ming was in the refugee camp of the Luhua District Police Department, he had already discovered that Jiang Wei was very cautious, and he also knew how to judge the time.

The elder was deep in thought, and he didn't know what was going on in his heart.

"Elder Guo?" Tianpeng shouted.

"Oh." The elder reacted immediately.

"What were you thinking?"

"Nothing, let's move on." The elder gestured to the hologram on the wall.

"Elder, I would like to ask, does our area belong to the first layer of the underground? Is it 10,000 meters underground? ”

"That's right, on land, we're 10,000 meters underground. However, we underground people are used to using the seabed as a reference, because most of the earth is the ocean, so we are used to calling it 5,000 meters underground. ”

"The ocean is above our heads?"

"That's right, but the first layer isn't just below the ocean."

"I know, each layer is built almost around the earth, like a ring. It's like dividing the earth into 11 small circles, and the surface is the largest circle, right? Jiang Wei said suddenly.

"You have to divide it that way, but the structure of the underworld is complex, and it's not just a circle. For example, in the abyss, some abysses in the first layer can be connected to the third layer underground. Besides, it is impossible for the ancestors to really dig 10 circles around the center of the earth, and if they do, the interior of the earth will become very fragile, and the natural reaction of the earth's core alone can shatter the earth. ”

"Oh, okay."

"If you think about it this way, the area of the entire underworld is only close to the surface area, which means that most of the 10 circles are semi-circles, and some don't even have half circles. In particular, the 9th and 10th floors of the underground layer have the lowest range, only one-third of the circle. ”

At this time, a crackling sound suddenly sounded outside.

"What's going on? Gunshot? Jiang Hao said vigilantly.

"Don't worry, it's firecrackers, how can you not tell the difference between gunshots and firecrackers?" The elder said.

"I'm sorry, I've heard too many gunshots, so I'm a little sensitive." Jiang Hao said with a smile.

"Why did the firecrackers suddenly go off?" Tianpeng asked.

"Because it's a holiday." Jiang Wei exclaimed excitedly.

"What holiday?"

"On the New Year's Day, there are two New Year's Festivals, a small year and a big year in the underground world, and the meeting will become more and more lively. Well, I'll arrange where you live, and then you change your clothes, and have a good evening for the festival. Anyway, the future is long, if you have any doubts, there will be opportunities in the future. The elder laughed.

"Uh-huh, okay, thank you so much." Tianpeng replied.

Half an hour later, Tianpeng and the others took a flying (flying vehicle) to a residential area, where the architectural style is very futuristic.

Everyone didn't need to take the stairs or the elevator, and they flew directly to the suite where they lived.

The 12th-floor suite is very spacious, with seven or eight rooms, and you can't even share one room for everyone. Each room has its own bathroom, which is very convenient.

Except for Jiang Wei, who was watching the giant screen TV in the living room, everyone else went to their respective rooms and bathrooms, planning to take a good shower.

It's been two months, and in these two months, everyone can't take a good shower, and today I can finally be clean and clean again.

About dozens of minutes later, Reverse Scale and Jiang Hao took a shower one after another, and changed into new clothes, they came to the living room and saw Jiang Wei sitting on the sofa, swaying her legs and watching TV.

This TV in the living room, located in the middle of the living room, does not have a physical screen, and the picture is realized through holographic image technology.

On the front of the screen, you can see the front image. Behind the screen, you can see the reverse image, which is very interesting.

The reverse scale walks directly around the screen, and also crosses the screen several times.

Jiang Wei said unhappily: "Why are you walking around?" Annoying? ”

"It's such an amazing thing, I'm just curious. Anyway, you girl, you have a lot of temper. "Reverse Scale is not a person who likes to be used to little girls, even if the other party is a Lori.

"Does it have anything to do with my temper? It's not right for you to walk around and get in the way of others. Jiang Wei shouted not to be outdone.

Jiang Hao hurriedly ran over to pull away the reverse scales, and said to Jiang Wei with a smile: "Okay, okay, this little thing, there is no need to be so serious." ”

"It's better to be Uncle Jiang." Jiang Wei replied with a smile.

"You can't get used to this kind of little girl, otherwise she won't be big or small." Reverse the scale is not cool.

"Okay, kid, what are you doing?"

At this time, Tianpeng came out of the room, and he looked at everyone who was basically ready, only Liming.

"Isn't Liming okay?"

"Don't you understand that girls take a lot of time to take a shower?" Jiang Wei replied.

"Okay." Tianpeng would never argue with Jiang Wei, he suddenly began to look around on his own, as if he was looking at the details of this living room.

"What are you looking at?" Jiang Wei said curiously.

"See if there's anything suspicious."

"Are you looking to see if there's surveillance or something? No, how can there be surveillance inside the residential area, it is against the law. ”

"Yo Yo, you even know the laws here."

"After all, it's been about a month."

"About a month," Tianpeng suddenly turned to Jiang Wei, "In that month, I really wronged you." ”

When Jiang Wei heard this, tears suddenly flashed in her eyes, and she remembered the days when she wandered alone underground. was first captured by zombies, and was enshrined as the main dish of the gluttonous feast, and was almost eaten. After finding a chance to escape, he got lost underground, and later in order to survive, he began to eat insects and all kinds of strange plants......

Jiang Wei thought about it, hugged her legs with both hands, curled up, and her eyes glistened with tears.

"Alright, it's okay, I'll definitely take you out of the ground." Tianpeng gently stroked Jiang Wei's head.

"Can I leave?"

"There must be a way."
