Underground world, light.

The netizens in the studio were very surprised.

Ning Fei also thinks it's weird.

"There's light here!"

"Light comes from the front."

"This light is natural light, not the light of flame and lamp!"

"The underworld can bring light down. How did they do it?"

Ning Fei mumbles to himself.

All these things are very magical.

There were many houses in front of him again, and in the distance of the houses, you can see a place with light falling, and there are water sources in that place, and even a lot of green plants.

"I'll go!"

At this time, Ning Fei suddenly retreated.

His action, let netizens are Leng for a while.

What's going on? 】

[has Ning Guanzhu found anything? 】

when you look carefully, you find that a large locust is flying towards Ningfei, and then Ningfei hides easily.

[it seems that insects are what Ning Guanzhu hates most. 】

[this is not affectation. I also have insect phobia. I feel uncomfortable when I see insects. 】

[+ 1, I really think this creature is disgusting. 】

[my mouth is watering. How delicious it is to fry such a big grasshopper! 】

Ning Fei looks at the grasshopper 5-6cm long.

"There are so many grasshoppers in the underground world."

"I heard that there was a plague of locusts in Lop Nor before. Locusts were all over the place

"I guess it might have something to do with this place."

"I have to see how the underground light comes from. Is it difficult for people in peacock city to make a sun?"

The scene is very strange.

The light around is not too bright, but it's not dark. It's like dusk.

In any case, it's against science.

Because under the ground, there should be only a dark environment.

Ning Fei passes through the house quickly and goes straight to the place where the light source appears.

Netizens also watched the scene nervously.

In the live broadcast, Ning Fei is wearing a Taoist robe, calm and indomitable in a slightly dark ancient city more than 2000 years ago.

[would you rather watch the Lord than be afraid? 】

[in the dark underground ancient city, the terrible ape may come out at any time. Normal people are scared to death in such an environment! 】

[is this the courage of a monk? 】

[in the vicissitudes of life, the brave have no words. Maybe that's the feeling. 】

the ancient city is much bigger than expected.

Ning Fei walked for nearly 20 minutes before finally passing through the old city and coming to the outside of the city.

"Something's wrong!"

"I've come all the way. The city is completely symmetrical."

"If I read it correctly, it should be a small gossip city!"

"The foundation of peacock city is eight trigrams?"

Ning Fei walked through the main city of this ancient city and said softly.

Netizens are surprised to hear this.

[Bagua city? In reality, there is a gossip City, just in the new stiffness! 】

[no, we had it more than 2000 years ago? So powerful? 】

[what's the matter with Ning Guanzhu saying something's wrong? 】

[you see the expression of Ning Guanzhu, he seems very confused. 】

[yes, it's rare. 】

at this time, Ning Fei explained:

"in Loulan's time, people here believed in Western Buddhism or local sects."

"Eight trigrams are Taoist things."

"I can't believe that peacock city has the origin of Taoism!"

"That's why I'm surprised."

Ning Fei explained softly.

After hearing Ning Fei's words, netizens understood.

In those days, there were few Taoist elements in the customs of the western regions, so if peacock city was really a city of eight trigrams, it would be strange.

Ning Fei has come to the outskirts of the city.

There are several walls, which are densely covered with vines, and there are many wild fruits on the vines.

Further on, you can see that the wall is very wet, and there is water flowing down the wall, like a water curtain.

Then Ning Fei raised his head.

UAVs also follow suit to shoot scenes overhead.

It doesn't matter. Everyone is confused.

How could that be! 】

[what's that? 】

[lying trough! What do I see! 】

the netizens were stunned and couldn't make a sound for a long time.I saw Ning Fei's head, and there was light falling down through the soil!

One by one light through the gap, although very weak, but still visible to the naked eye.

Ning Fei's face is also a change!

Immediately, when he looked carefully, he understood.

"That's a special kind of glass!"

"The earliest glass in the world appeared in ancient Egypt in 3700 BC, and glass beads were produced in the ruins of ancient Egypt 4000 years ago."

"I didn't expect that a small country on the border of China for two thousand years had the ability to refine glass."

"This kind of glass is buried under the sand. It looks like soil from the outside, but when there is sand, some sand will be blown away and light will fall down."

"In this way, peacock city is not forced to sink into the ground!"

"But someone has done a big project to let peacock City sink to the bottom of the earth voluntarily."

"This is a city voluntarily buried!"

Ning Fei looked at the weak light above his head, and he finally understood.

"More than two thousand years ago, Loulan wiped out the small countries around it and realized unification, including peacock City," he said

"After that, the Peacock River stopped flowing, and there was no water around Loulan. Desertification became more and more serious."

"The people of Loulan are forced to move their capital. All of them have to leave this land and go outside to survive."

"But the people in peacock city are not with Loulan."

"Some people predicted that this place would be buried by wind and sand, so they made an amazing decision with the help of the whole country!"

"Let peacock City sink underground."

"It's an epic project. In terms of difficulty, it's no less than that of the Great Wall."

"And among them, there must be a great man who knows the technology of glass making and engineering."

"They built a roof for peacock city!"

"Here is the place of light!"

Everyone was shocked to hear Ning Fei's words.

They are not free from Ning Fei's words.

How is that possible? 】

[what is Ning Guanzhu talking about? 】

[I probably understand what Ning Guanzhu meant. In Lop Nor, the lakes disappeared, the wind and sand filled the sky, and the ground of peacock city was covered with a thick layer of sand. 】

[then the people of peacock city began to build projects to build walls and roofs over and around peacock city. 】

[after that, the wind and sand became more and more and bigger until the city was completely buried. 】

[just, is it possible? 】

netizens were shocked.

At this time, Ning Fei looks at the dark ancient city.

At this moment, he was also a little nervous.

He rarely felt that way.

Then, Ning Fei said softly:

"it's very easy to verify this conclusion."

"If the people of peacock city do not leave, they will be buried with the city voluntarily."

"I'm afraid there will be several bones in each of those hundreds of houses!"

Hear Ning Fei's words, netizens instantly sweat like electric shock erect up!

Even in the spring season, everyone feels cold from head to toe!

Hundreds of houses, thousands of bones!

This is the real purgatory!
