The building exposed to the ground, the ground should be a square, about 10,000 square meters in size, this building, about two or three meters above the ground, but Su Peng and others have seen that this building is not only so much on the surface, plus the part that falls into the ground, it should be an inverted triangle, and there is still a lot of space deep underground.

The exterior of this building is all black stone, which looks smooth and has a bit of a sci-fi feel.

"This ...... How could such a building come about? ”

Seeing this building, Cai Junhua forgot for a moment, his eyes stared at this building, and he muttered.

"Brother Cai, do you know this building?"

Su Peng looked at Cai Junhua, who was a little excited next to him, and asked him.

"Buildings that resemble regular triangles are not uncommon in history, such as the quadrangular pyramids of Egypt and the sub-pyramids of the Mayans, which are generally of this shape...... Some people say that this represents some kind of alien civilization that once appeared on the earth, but in fact, in my research and understanding, this should actually be a relatively simple figure worship. ”

Cai Junhua looked at the upside-down quadrangular pyramidal building in front of him, touched his professional nerves, and explained to Su Peng.

"In fact, our country is not without this kind of graphic worship, although at the beginning of the ancient tombs unearthed in our country, roughly the cross-section of the trapezoidal octagon, as well as the circle of two, but according to our research some early life in what should be the history of the barbarian land of Miaojiang, there are some similar places, have found some regular triangle tombs, but the size is not large, according to Junhua's research, this should show that there has been a kind of quadrangular pyramidal figure worship with a regular triangle in all parts of the world."

Liang Wei added beside Cai Junhua, and then said: "This is actually a topic that I am studying in reality. Junhua also made a lot of efforts. ”

"Oh? What do you two have learned? ”

Hearing this, Su Peng asked the two of them.

Cai Junhua and Liang Wei both shook their heads, and Cai Junhua said: "In reality, whether it is the pyramids left by the Mayans or the pyramids of Egypt, they are all very closely protected. You can't go into the field at all, so you can only stay on paper research. ”

"But fortunately, we also have some information about this kind of building, and it seems that although the inverted pyramid-like structure in front of us is a little weird, there should still be some commonalities in general, and we might as well follow the map and we should be able to enter."

Su Peng nodded, the river in front of the three of them was very easy to cross, and Su Peng found a place with a reef in the middle of the river. Perform your tricks and leap over.

Although Cai Junhua and his wife are a little inferior to Su Peng, they are also of sufficient grade, and it is not too laborious to cross this underground river from here.

"Brother Qi. Let's find out, according to the Egyptian theory, the West is the direction of death, and we don't know what the meaning of the pyramid architecture is. But if it's about death, then it must have a door, in the West. Or the opposite direction of the West to the East. ”

Cai Junhua and Su Peng said.

Su Peng listened and nodded, he had a good sense of direction, he could still sense the direction all the time, and after looking around, he found a clue in the place that should be in the east.

I saw that in the east of this inverted pyramid, Su Peng found a place like a totem painting on the black stone wall of unknown material.

Su Peng glanced at the totem painting and immediately frowned slightly.

And Cai Junhua and Liang Wei, who didn't search for anything, also came to Su Peng's side at this time.

The two also saw the totemic paintings on the stone walls.

I saw that on this mural, there are intricate pictograms of flames, suns, and snakes.

In the middle of this figure, there is another depression, and this depression is a pentagonal shape.

Cai Junhua walked here, looking at this pictogram, looking at the depression, and constantly touching the stone wall with his hands.

After a while, he said: "If you guess correctly, this should be the entrance, this recessed place, should be the place where the key to enter the underground is placed, and this whole building, I don't know what the road is made of, I just touched it, it looks like a black stone, but it is much harder, look at the smoothness of the outer wall, maybe this thing is also very good corrosion resistance, although it is estimated that it may have been placed here for thousands of years, but there is no corrosion and deformation at all, it is incredible." ”

Su Peng looked at the depression and was slightly surprised in his heart.

He reached into the Qiankun bag he had placed in his arms, fumbled for a while, and found something.

Cai Junhua and Lian Wei looked at Su Peng's hand, and saw that in Su Peng's hand, there was an extra pentagonal token, and on this token, there happened to be a complex image of flame, sun, and flying birds, which was exactly the same as on this stone wall, and it was completely carved out of a mold.

"Huh?"

Seeing this token, Liang Wei couldn't help but exclaim, and looked at Su Peng with some surprise in his eyes.

Cai Junhua also showed surprise in his eyes and looked at Su Peng.

Su Peng saw the reaction of the two and smiled bitterly, which was not surprising to the two of them.

This expedition was originally found by the two of them, and along the way, Su Peng also acted according to the guidance of the two, but at the most critical time, when he was about to enter the underground palace where the treasure might be hidden, Su Peng, an 'outsider', suddenly took out a token like a 'key' that could enter the underground palace, if Su Peng was Cai Junhua, it was also surprising.

Because this makes people can't help but think, is it not impossible for Su Peng to know that there is such a palace here, and then coax Cai Junhua and the others to come, in that way, Su Peng will become ill-intentioned, and even enter the palace for a while, or before that, it is not impossible to kill Cai Junhua and his wife and monopolize the treasures of the palace under them.

After all, Su Peng has already mastered the path back and forth.

Thinking of this, Cai Junhua couldn't help but stand half a step forward and blocked Su Peng in front of Liang Wei.

Seeing Cai Junhua like this, Su Peng smiled bitterly and said, "Don't misunderstand, I just found out that I have this thing on my body......"

After a pause, Su Peng continued: "I swear I didn't know that the underground palace here in Lu Dao is like this, my token was obtained half a year ago, thousands of miles away, in a place called Thousand Eyes Swamp, from a person who strayed into an underground palace in a swamp, I didn't know what the function of this thing was, and then I kept it on my body, but I didn't expect it to be used at this time, it was completely a coincidence." ”

After listening to Su Peng's explanation, Cai Junhua and Liang Wei felt better, and the two couldn't quite accept that Su Peng deceived the two of them so much along the way.

Su Peng didn't lie either, this was the token he got from him when he went down the mountain to return to Jiangning County, when he went to the Thousand Eyes Swamp to look for Ling Xiaoyu, he killed Song Zhong who turned into a zombie in the swamp.

It's just that I didn't know what the function of the token was at that time, so Su Peng kept it, but he didn't expect it to be used here.

Su Peng explained the matter in detail, and only then did he dispel Cai Junhua and Liang Wei's concerns.

"I see...... It seems that the mysterious tomb in the Swamp of the Thousand Eyes may be inextricably linked to this place. ”

Cai Junhua said.

"Well, but for now, we should see if we can open the mechanism of this underground palace."

Su Peng said, as he spoke, he took the token and pressed it down on the depression in the east of this inverted pyramid! (To be continued......)
