"It's just us sisters here! There used to be a grandfather, but he died a long, long time ago. ”

The girl in the white shirt said.

At the end, a touch of sadness flashed across her face.

"Yes, the old man has been with us for a long, long time, and suddenly he is gone. ”

The girl in blue also said sadly.

"I'm sorry. ”

Seeing this, Shi Lin said apologetically.

"It's okay, it's been a long time. ”

The girl in the white shirt said with a smile.

"Huh, there's someone else coming in?"

At this time, the blue-clothed girl on the side suddenly sighed softly and looked at Shi Lin.

The girl in the white shirt also looked at the stone forest.

"Yes, there are a lot of people here this time. ”

Shi Lin said.

"Are they with you?"

The girl in the white shirt asked.

"No, I'm alone. They are adventurers from all over the world, or experts sent from various countries. ”

Shi Lin said.

"Country, what are the countries on the earth today? Is it still China, Barhambi, Egypt, India, and a few other countries?"

The girl in blue asked, tilting her head.

"Are these all in your books?"

Ling Zhou asked without answering.

"yes!"

The girl in blue blinked and laughed.

"Well, you're right, but you're not entirely right. The countries you mentioned, except for Huaxia, although the others are still under this name, they are not the original countries. Egypt, for example, was destroyed thousands of years ago. Although the name Egypt has been passed down, it is not the same Egypt as it was, but a new country. It has nothing to do with ancient Egypt. ”

Shi Lin said.

The four ancient countries of the earth, and only Huaxia have inherited them on the earth, with a history of 5,000 years. As for the other ancient countries, they have long since disappeared.

"Thousands of years. ”

The girl in blue pursed her lips.

"Let's go, let's go to the end of the world and look at the earthlings of this era. ”

The girl in white said with a smile.

"Hmm!"

The girl in blue nodded, then walked to Shi Lin's side, grabbed Shi Lin's arm, and said, "Little brother, let's go over together." ”

"They're on the other side of the cliff?"

Shi Lin asked.

"Yes, but they won't be here. ”

The girl in blue pulled Shi Lin's arm and said with a smile.

"Why not? It's only a hundred meters away!"

Shi Lin wondered.

With the wisdom and technology of modern human beings, it is not easy to cross the 100-meter-wide cliff, but it is also difficult.

"It seems that the little brother has already been to the end of the world, but you don't know that there is only one passage to come here, which is the place where you have walked through. Anywhere else, it's impossible to get here. ”

The girl in the white shirt said.

Shi Lin frowned and wondered.

How can't you?

"You'll know when you go and see it. ”

The girl in blue said with a grin.

Shi Lin nodded, didn't say anything, and followed the girl towards the cliff.

……

Soon, they came to the edge of the cliff.

But it was too big, and they walked for a long time before they saw someone coming.

Shi Lin wondered, how did they find out in time?

Could it be that some kind of mechanism is over there? Those adventurers touched the mechanism and came here?

However, they had been there before, so why didn't they find out?

There are too many puzzles, which makes Shi Lin puzzled.

Although he was puzzled, he didn't think much of it, and looked up at the other side of the cliff. There, at this time, more than 30 people had gathered. They looked at their side, their eyes wide and shocked.

"God, is this a miracle? These buildings have been around for 8,000 years?"

"However, our human history is only a few thousand years? The history of China is only 5,000 years, and there are 8,000 years. ”

"This is an earth-shattering discovery!"

"Not to mention how long these buildings have existed, it is unimaginable that such a huge complex can be built under an unknown number of meters. ”

"Quick, find a way to report above. In addition, send drones to the cliff side to investigate. ”

“……”

A group of explorers from various countries or forces were amazed and carried out the next action plan. They currently have no equipment and no way to cross the cliff, so they can only explore with drones first.

……

"What's that?"

On the other side of the cliff, the girl in blue pointed to the drone and asked Shi Lin.

"That's a plane, don't you know?"

Shi Lin said with a smile.

"No, it's not an airplane, in the classics left by our ancestors, it is recorded that contemporary humans can fly in the air, but in an iron box, it should be the airplane you said. But there's no one up there!"

The girl in the white shirt asked.

"Yes, but it's a manned aircraft, it's a drone. It was developed by modern people and specially used to carry out some exploration and reconnaissance missions. People can know some secrets through drones. ”

Shi Lin said with a smile.

At the same time, I once again had a strong curiosity about the classics in their mouths.

Even the plane knows.

It gave him the urge to look through the tome and get a glimpse of what's to come.

"Little brother, do you want to look through the classics left by my ancestors?"

The girl in white asked suddenly.

Shi Lin was speechless, there was no expression on his face, he just thought in his heart, how did she know?

"Hee-hee, little brother, don't think about it. If you came 10 years earlier, those texts would still be useful to you. But it's late tonight, haven't you seen it, we don't even know about drones? Those classics were written by our ancestors 100,000 years ago, but at this age, we can't afford to write them down. ”

The girl in blue said.

"If you want to see it, I'll go to our house and show it to you later. ”

The girl in white smiled.

"Hmm! How do you fix that?"

Shi Lin asked.

He didn't know what would happen if people from the outside came here.

"Brother, didn't we say it before? They can't get through. They can't come from anywhere except the passage you've walked through. And the passage you walked. It takes a lot of power to open it. ”

The girl in blue said.

"Ten thousand pounds of power!"

Lori smacked his lips, if what they said was true, then no one would be able to come in.

Apart from him, who else on earth has the power of ten thousand catties?

It's just that the width of that cliff seems to be only 100 meters away! With current technology, although it is 100,000 meters underground, it is only a matter of time before you want to get over.

"Little brother, have you forgotten what I just said? This cliff is called Tianya. The end of the world is close at hand, and no one can come over. ”

The girl in the white shirt smiled.

"Why does that sound so mysterious?"

Shi Lin glared.

"That's the magic of nature. ”

The girl in the white shirt said.

"So, will the drone be able to fly over?"

Shi Lin asked again.

"No, it won't. ”

The girl in the white shirt said.

Luo Li couldn't help but glance back, it was obviously very close!

After thinking for a while, he didn't think about it anymore, and followed the two mysterious little girls towards the depths of the complex.

"I don't know your names yet. ”

On the way, Shi Lin asked.

They seem to be physically weak, but they walk unusually fast, just like ordinary people trotting, but they obviously walk again, and they seem to walk unhurriedly.

"My name is White Shirt and her name is Blue Shirt. ”

The girl in the white shirt smiled.

Shi Lin was speechless, looking at them, not knowing if they were perfunctory or if they were really called by this name. The name is too arbitrary, isn't it?

"Little brother, I am indeed our name, which our grandfather gave us at the beginning. ”

It seemed that Shi Lin was a little unconvinced, and the blue-shirted girl said with a smile.
