Ye Tian quickly took off the head of the six-pointed golden scepter embedded in the stone gate, put the priceless treasure into the mountaineering bag, and then reached out to push the stone gate completely open.

With his movements, the secret passage behind the stone gate, which had been closed for at least a thousand years, finally appeared in front of everyone.

The entrance of this ancient secret passage is about two meters high and about one meter eight meters wide. It looks like an irregular door, but it is made of extremely hard and extremely heavy granite.

After more than a thousand years, this stone gate has completely integrated with the environment on the cliff outside. If it weren't for Ye Tian, ​​others would never have discovered the existence of this stone gate.

Entering through this gate is a winding secret passage that leads to the abdomen of the mountain.

Where is the end of this secret passage, how long is it, whether there are deadly mechanism traps in the secret passage, and whether a large number of highly toxic creatures are growing and entrenched. All of this is unknown for the time being.

Moreover, the more the secret passage goes, the larger the space. Looking inside from the door, the ground near the entrance of the secret passage is quite flat, and the walls on both sides are the same as the top above. The ancient Mayans should have deliberately repaired it.

Entering from the entrance, about three meters inside, there are several steps downward.

Only by walking down those steps can you truly enter this secret passage. As for the terrain deeper in the secret passage, you can't see it for the time being. The depth of the secret passage is now covered by darkness.

Fortunately, or unexpectedly, there was no dirty air or poisonous fog accumulated in this secret passage, and no poisonous insects and beasts suddenly rushed out from inside to hurt people.

On the contrary, the air blown from this secret passage is actually very fresh and moist, and seems to be a little better than the air in this tropical rainforest where everyone is.

Obviously, this dark secret passage should not be too long and is connected to the other side, so air convection is formed.

Ye Tian stood on the side of the stone gate for a while, and after confirming that there was no danger, he came directly in front of the stone gate and looked into the secret passage.

With the help of natural light illuminating into the secret passage, the situation at the entrance of the secret passage was immediately presented to his eyes.

At the entrance of this secret passage, the ground and the walls on both sides are covered with moss and dust, and there is no visible ground and walls covering the bottom.

The top of the cave was also covered with moss, and there were also a few tree roots or vines that spread along the cracks of the rocks, hanging down directly from the top of the cave.

Because there is no light entering this secret passage and lacks photosynthesis, there are no other plants here except for moss and the roots of those trees and vines.

In addition, on the ground of this secret passage, you can also see many traces and footprints, including traces of snakes crawling, footprints of small animals, and even footprints left by jaguars.

From this point of view, the other side of this secret passage should be open, so those animals can enter this hidden secret passage, but are subject to the stone gate here and cannot access the rainforest here through the secret passage.

Ye Tian stood at the entrance of the cave and pretended to be careful to check the situation in the secret passage, then stretched out the jungle machete in his hand and scraped off a piece of moss and dust from the left wall at the entrance of the secret passage.

With this action, the dust and moss covering the wall immediately fell down.

The next moment, a wet granite wall appeared.

You can see that on that wall, there are several Mayan hieroglyphs, and there seems to be a stone mural with only one corner exposed, and the rest is covered with moss and dust.

Ye Tian looked at the Mayan hieroglyphs and murals, then looked at the depths of the secret passage, and then said aloud:

"Professor Delgado, Hernando, you can come up. As for the current situation, the secret passage behind the stone gate is relatively safe, and there is no dirty air or poisonous gas escaped from it.

For safety reasons, there should not be too many people coming up to check the situation. The rest of the people wait. We will thoroughly explore this secret passage and make sure there is no danger. Let’s go into it and check it.

Mattis, Jason, you come over with two small drones and put them into this secret passage, check the situation in the secret passage, see where this secret passage leads to, and prepare for the next step of action!"

As soon as the words came, a response immediately came from behind.

Immediately afterwards, Professor Delgado and Hernando walked up quickly, with a total of six people, each of whom was extremely excited and full of expectations.

When they arrived in front of the stone gate, the guys immediately looked into the secret passage, turned on the strong light flashlight they carried, and shone it into the depths of the secret passage.

The next moment, there were a few more powerful beams of light in this dark secret passage, each shining towards different corners.

As these beams entered, the situation deeper in the secret passage suddenly appeared in front of everyone.

Unlike the entrance to the secret passage, the depth of this secret passage is like a naturally formed cave. Although there are many traces of Mayan trimming at the entrance to the secret passage, it becomes more and more primitive as it goes inside.

Especially at the top of the cave, about seven or eight meters from the entrance, there were a lot of hanging stalactites on the top of the cave, dripping water downwards, and small puddles were smashed on the ground.

In addition to the water holes, there are several small ditches on the ground inside the cave, crisscrossing, guiding the water dripping from the top of the cave to avoid causing a large amount of water accumulation.

These small ditches were all connected together and eventually led to a corner of the cave, where there happened to be a small hole, and the accumulated water in the cave eventually flowed out.

From this we can see that there should be a stream on the other side of this cave, or an underground river below the cave, which can lead all the accumulated water here.

Another point is that the entrance of this cave is about thirty centimeters higher than the inside. When entering from the entrance, you need to go down three steps to reach the ground.

In this way, even if water accumulates in the cave, it will not overflow from the entrance, exposing the location of the entrance.

Obviously, after the Mayans discovered this natural cave, they used it. Although the design was very primitive, it was very practical!

They knocked off the stalactites on the top of the cave at the entrance, sorted out, designed and created a hidden and heavy stone door to hide the cave.

They didn't deal with the depths of this cave, at least they didn't knock off the stalactites on the top of the cave, and retained some of the original appearance.

Unlike the situation at the entrance of the cave, there is no plant in this cave. Even the roots of large trees with extremely strong vitality are difficult to break through the hard granite.

Deep in the cave, there are only dripping water drops, and stalactites of various shapes hanging on the top of the cave.

In addition, in the depth of the cave, two stone statues stand against the walls on both sides, covered with moss and dust. It is not clear what the carving is.

Several powerful beams continued to extend inward, extending to a depth of thirteen or fourteen meters, but were blocked by an arc-shaped turn and could not move forward any further.

As for the situation behind the turn, there is no way to know for the time being, so I can only explore it with a small drone later.

Looking at the situation in this secret passage, Professor Delgado, Hernando and others standing at the entrance were all excited, and screams came one after another.

"Wow! This cave is really big. I wonder how the Mayans discovered it? How did they transform and utilize it? What is the other side of this cave? Is it the legendary Golden City?!"

"The Mayan hieroglyphs and stone murals carved on this wall record a battle. This battle should be very famous. I looked familiar, but I couldn't remember it for a moment."

Looking at these guys who were shouting, Ye Tian just laughed softly and didn't say much.
Chapter completed!
