"Where is this?" Looking at the surrounding environment, Liu Ye was suspicious.

Just when the four of them thought they were going to be finished, a staircase suddenly appeared under the circular building where they were hiding, leading them to safety.

The walls here, like the rotunda outside, exude a soft 'mist' and 'mist' light. If it weren't for the extremely bad situation they were in, the four of them would almost have thought they had entered a wonderful environment.

"Please come out to talk about the friend who saved us, Liu Ye is overwhelmed with 'excitement'!"

The four of them shouted inside the building for a long time, but no one responded.

"What's going on? Is there no one? And who saved us just now? "Four people are strange.

After a long time, an old voice slowly sounded in the air, and the accent was also very weird, a bit similar to a foreigner speaking Chinese, which was very awkward.

"Hello, visitors from the earth!" The voice said.

"Thank you for saving us, I wonder if I can tell you who you are?" Although the other party saved himself, Liu Ye still held a trace of vigilance.

This underground city seems to have a great prejudice against the people on the ground, and it is difficult to guarantee that nothing like this will happen here as it does on the ground.

"Alas! It's a long story! Come with me, I'll talk to you slowly! The voice paused for a moment and said slowly.

As the words fell, the wall in front of Liu Ye and them automatically opened, revealing a channel that emitted a glow.

The four hesitated for a moment and walked up the aisle. So far, we can only take one step at a time.

Walking through the passage, the front suddenly opened up, and what appeared in front of Liu Ye and them was an empty square.

"This ......"

For the environment in front of them, Liu Ye and the others were completely in a state of shock.

This is because the area is so large compared to the exterior of the building that the building simply cannot accommodate such a vast space.

"It's not a fantasy!" After Menglong's identification, Liu Ye knew that this square was true inside and out, but he was still skeptical of Menglong's judgment.

"Distinguished guests, welcome to the Underworld, New Maya, and I would like to extend my welcome only on behalf of the original inhabitants here!" The old voice sounded again.

With the appearance of these words, I saw a huge stone slab slowly rising around the square. About five or six hundred people stood on the stone slab, and one of them, an old man in a wheelchair, with a soft glint in his eyes, was watching them.

The skin of these people is somewhat similar to that of the Indians of North America, and they all exhibit a pulsating red 'color'.

"New Maya? According to historical research, the Mayans seem to belong to the red 'color' race! Looking at the unique skin 'color' of the crowd on the slate, Liu Ye felt relieved.

"Aboriginal people? What do you mean? Could it be that there are other alien races here? Nan Tiancheng, who had a keen sense of smell, asked, and he first felt a little difference.

"This gentleman is very smart, I haven't said much, I've already guessed eight or nine!" The old man in the wheelchair laughed.

"Alien race?" Liu Ye and the four of them glanced at each other, and a 'fine' glint flashed in their eyes.

"This thing is very troublesome, you better come up, I'll show you an understanding!" The old man took a deep breath and said as if he had made some kind of decision.

"Patriarch!" An unusually strong red-haired young man beside the old man was a little surprised, and he spoke out as if he wanted to stop the old man's decision.

"Needless to say, I believe them!" Although the old man was old, he had a very high prestige in the crowd, and when the others heard the old man's affirmative words, they did not say much.

"Come up, please!" The old man slowly stretched out a hand and invited Liu Ye and the four of them to say.

The four of them glanced at each other and boarded the stone slab with the doubt in their hearts.

The slate continued to climb upward, and what made Liu Ye and the others feel extremely awkward was that they could see that the building was so high, but no matter how high the slate was, they couldn't see the top floor of the building.

"Isn't this the space folding technology that all countries were secretly developing before the war? Could it be that the people here have already applied this technology to people's livelihood? Liu Ye was shocked.

The scene just now may be said to be the effect of another technology, but the scene in front of him has no other explanation except for space folding technology, and Liu Ye has to believe it.

As for what kind of energy the slate is based on and can rise in the air like this, Liu Ye doesn't want to delve into it, after all, in the face of this advanced space folding technology, other high-tech has been eclipsed.

After about ten minutes of ascent, the slate finally stopped. The old man pushed the wheelchair forward slowly, and his trembling right hand swiped in the air, only to see that the empty air immediately changed.

"...... this?" Although he was already a little numb from shock, Liu Ye was still taken aback by the changes in front of him.

Ten quaint and heavy huge stone tablets suddenly appeared in the air, each of which was the size of the stone slab under Liu Ye's feet, hanging heavily above their heads, giving people a sense of fear and depression.

"These are all real stones, and the Dream Dragon can scan the 'emission' and 'sexuality' reactions of each stone, and the age of each stone is about 5,000 years old!" Liu Ye was shocked in his heart.

After the ten stone tablets hovered in the air for about half a minute, the top began to change, and one after another pictures appeared on them.

The picture begins with the first stone tablet, which is first a deep darkness, and then the darkness suddenly shrinks into an extremely bright point, which then explodes with greater brightness.

Then many small bright spots appeared in the deep darkness, bringing a lot of light.

"It's ...... The Formation of the Universe!? "How can I say that Liu Ye is also from modern society, no matter how shallow his knowledge is, he still has this common sense.

"As early as 5,000 years ago, the Mayans already knew about the formation of the universe?" Liu Ye's heart was even more shocked.

This is followed by a second stone slab, which shows the formation of life on Earth, the biological condition of the various eras.

To the third slate, it is the birth and development of the Mayan tribe, these things Liu Ye knows a thing or two, after all, there are many historical reports in the past.
