There was a hole in the cliff wall, and the convoy drove directly into it.

Not far in, there was a huge iron gate, a female soldier in the front team got out of the car, knocked on the iron door, and after a while, the iron gate opened, and the convoy drove in.

Behind the iron gate, there is a tall underground passage, and there are hanging ceiling lights, and every 100 meters or so, there is a lamp.

Seeing Yang Dingtian's somewhat surprised look, Barbara laughed: "Aren't you surprised?"

"There's electricity. "The tunnel is okay, there is electricity, it is really unexpected by Yang Dingtian.

"This was originally a base, built with the help of the former Soviet Union. Barbara explained: "The whole base is hidden in the depths of the Devil's Sea, in the belly of the mountain, and the underground passage inside is a full hundred kilometers long. ”

"Awesome. Yang Dingtian sighed: "It is worthy of being the overlord of the Cold War, it is really courageous, what is there in this base?"

"A whole ten divisions of weapons and equipment and food for the soldiers to eat for three years, a reserve of medical and daily necessities. ”

"Ten divisions, three years. ”

Yang Dingtian couldn't help but sigh again.

At that time, the United States and the Soviet Union competed for hegemony and confronted each other in all fields of the world, and I really don't know how much money it spent.

"The president handed over this base to the guards division because he thought that if the situation was not right, he could retreat here, however. ”

Barbara shook her head at this.

Yang Dingtian can understand that Gaddafi took this place as one of his retreats, but in the end he failed to retreat here, but was captured alive.

Seeing that the convoy kept driving, Yang Dingtian said, "Where is Iman taking me now?"

"The Heart of the Earth. ”

"The Heart of the Earth?" The name was very strange, and Yang Dingtian was a little surprised.

Barbara laughed, "Don't you think Iman's temperament doesn't match what you imagined? ”

She didn't explain in detail, so Yang Dingtian didn't ask much.

The car drove in the underground passage for about an hour and stopped.

"It's here, get off. "Barbara should get out of the car first.

Yang Dingtian followed.

The convoy stopped in a huge cave.

This is supposed to be a natural cave, very large, with a ceiling of more than 100 meters, maybe 200 meters, forming a huge dome.

The area of the entire cave, Yang Dingtian estimated, at least the size of a football field, maybe even bigger.

There are a lot of lights in the cave, some of which are searchlights, and the Red Star Factory also has them, which are used to illuminate when playing blue at night, so the light in the cave is very good.

Iman got out of the car and saw Yang Dingtian looking at the cave, she didn't urge, until Yang Dingtian looked at her, she smiled slightly, and stretched out her hand: "Commander Zeng, please come with me." ”

As she spoke, she led the way to a hole.

Yang Dingtian followed.

Only then did he notice that Iman was very tall, about 1.75 meters tall, and if it was the body of Yang Dingtian, he would be a head shorter than Iman, but Zeng Lu was 1.83 meters, which was not short.

Iman is in very good shape, the white robe is soft and close-fitting, and when he walks, the hem of his waist has a softness like water, so that Yang Dingtian can't help but stare at it more.

"The way she walks doesn't look like a soldier. ”

Yang Dingtian's mind flashed.

But after thinking about it again, it is clear that Barbara said that Iman is not mainly trained as a bodyguard, but as a swallow, and her main business is actually to be a beautiful person, so whether it is her temperament or walking posture, she is more beautiful, and lacks the heroism of a soldier.

But it is a miracle that such a woman has led the beauty guard division to endure for more than ten years.

Of course, a leader, the most important thing, is not her martial bravery, but her wisdom, brain, and wrist, just like **, without a gun, rampant in the world, exposed, not domineering, but a poet's temperament.

Entering is a passage, about twenty meters or so, there is an iron door, there is an electronic code on the door, Iman pressed a few passwords, and the iron door slowly opened.

As soon as the iron door opened, Yang Dingtian felt that it was wrong, because there was light outside, although it was very dark, under the pressure of the light inside, it was not obvious, but it couldn't hide Yang Dingtian's eyes, and the smell in the air was not right, and the wind blowing in was very fresh.

"Could it be that you are out of the ground, and you are going to the ground? Isn't it talking about the heart of the earth?" Yang Dingtian was a little curious.

But he didn't ask.

"Please. ”

The iron door opened, and Iman made a gesture, still leading the way in front.

After passing the iron gate, about forty or fifty meters away, the light became stronger and stronger, but it was not particularly bright.

Just in Yang Dingtian's curiosity, the passage came to an end, and his eyes lit up.

"Ahh ”

The scene in front of him made him scream involuntarily.

He was amazed because he had seen a strange sight that he had never seen before.

He saw an incredibly huge hole.

How big is this cave, that you can't see the edge at a glance, and you even have the feeling of looking far away.

Yang Dingtian estimated that this large karst cave is at least four to five kilometers long from east to west, and wide from north to south, and about two to three kilometers.

The top of the cave is extremely high, the highest point, about two or three meters and 100 meters, and the shortest place, it is estimated that it can also be one or two hundred meters.

The light in the cave is not dim, but very bright.

This is because there are several fissures in the roof of the cave, the largest of which is about one or two hundred meters wide at the widest point, and seventy or eighty meters at the narrowest point, and it happens to be in an east-west direction.

In this way, the sunlight can be directly entered, and there can be light all day long.

There are about seven or eight such fissures, which gives enough light to the hole.

But the brightness in the cave is not entirely due to the light overhead, but also because of the water in the cave.

Inside the cave, there is a huge lake, which is half-moon shaped, accounting for about two-thirds of the area of the cave.

At this time, it is the time when the sunset goes down, the sunset shines in through the cracks, the light hits the surface of the lake, and then reflects to the top of the cave, so the whole cave is rippling with golden light, not only the light is extremely strong, but also gives people a dreamlike fairyland-like beauty.

Two-thirds of the cave is a lake, one-third is meadow, where sheep graze, and palace-like buildings near the water.

Where is this Devil's Sea, this is simply a fairyland.

This is the reason why Yang Dingtian has run so many places over the years, but he still exclaims.

This kind of underground world is really too strange and incredible.

"This is the Inner Sea?"

It took a long time for Yang Ding to wake up.
