Li Yan's figure had already buckled the safety buckle, and then his left hand was in front, controlling the angle of the rope and his body, and his right hand was behind, controlling the descending speed of the rope, and jumped out directly.

The rope is held to two nodes, the first of which is on an arm-like bulge in the rock.

This is the first attachment point of the safety rope, and the other attachment point is to a tree under the rock.

The tree grew horizontally on the cliff, the thickness of an adult's thighs, and its rhizomes were deep into the cliff, and it was very strong.

These two safety nodes are enough to ensure the stability of the rope.

At that time, even if the first node on the stone is cut off, the second node will ensure the safety of the rope.

If someone wants to cut off the second node, I'm afraid they can only get it with a gun.

After Li Yan fixed the second node, he glanced up at Tie Qinglan, and then said, "Let's go together, we don't need to answer and be vigilant." ”

Li Yan's location is very hidden, similar to a corner of a five-pointed star, showing narrow cliffs on the left and right, blocking most of the line of sight.

If anyone spotted them, it would only be from the opposite side of the sinkhole, right across from this corner.

And there is at least five hundred meters away from Li Yan's location in a straight line, so there is no need to worry about other safety hazards.

This location is difficult to be discovered, so Li Yan gave up his work as a vigilance.

Tie Qinglan didn't talk nonsense, looked left and right to make sure that no one was peeping on the side, and then began to rappel immediately after.

The height of the cliff of the sinkhole is about 50 meters, and although the vegetation below is dense, it can basically be judged that it is in the shape of a funnel.

Because both of them are masters, the speed of the rappelling is extremely fast, and it takes almost less than 30 seconds to land safely to the end.

"We still have a rope that we have to carry with us."

Li Yan commanded while observing the surrounding environment, quickly unfastened the safety buckle, and at the same time pulled Tie Qinglan's tactical scimitar out of his waist.

The environment inside the sinkhole is much more complicated than imagined, and here, it is completely the environment inside a sinkhole that is much more complicated than imagined.

It's a primeval jungle like no one has ever set foot in!

From above, it looks like a sinkhole, but when you come down, you realize that it is a typical tropical rainforest.

When I came down from above, the air was still cool because it had just rained before.

However, as soon as Li Yan and Tie Qinglan's feet touched the ground, they were instantly surrounded by an indescribable heat.

Almost instantly, the bodies of the two were drenched with sweat.

"Brother Yan, how do I feel like we're in the primeval jungle of the Amazon?"

As he spoke, Tie Qinglan had already taken out another captured tactical scimitar, and this large mountain opener was an absolutely indispensable tool for traveling through the jungle and mountains.

"Yes, it's like a dense canyon, and it has never been discovered or set foot in for thousands of years, and it is a unique ecological system that has formed itself as a whole."

Li Yan's gaze calmly and keenly observed the surroundings.

The vegetation of the dense forest below is unusually dense and complex, and the roots are intertwined as far as the eye can see, the ancient trees are towering, and the vines are like snakes.

The ground was covered in mud, and occasionally strange rocks appeared in the middle of the dense forest.

Tie Qinglan stretched out her hand and gently touched the stone wall on the side, and suddenly her fingers were covered with extremely slippery moss.

"The stones and tree trunks here are covered with this kind of moss, which is enough to see that this place has not been disturbed by people."

Li Yan raised his hand as he spoke, looking at his wrist compass, the direction he was going to travel was the middle part of this sinkhole.

Because he didn't have a compass or other feng shui tools, the next way was to walk towards the middle, and then look for possible caves or other terrain that could bring about changes.

"I wish it could rain a little later."

Tie Qinglan casually cut off an entangled tree root in front of her, and the sweat on her face was already flowing uncontrollably.

In such places, the biggest threat is dehydration.

Therefore, Li Yan and Tie Qinglan each brought two large kettles, each with about two liters of water.

As for whether it is enough, it is difficult to say.

Fortunately, there is no shortage of water here, as long as you know how to find clean ones.

"Let's go."

Li Yan didn't expect it to come and almost immediately entered the dense forest.

From above, the vegetation underneath was dense, but when they came down, they found that the vegetation here was even denser than they imagined.

If it takes an hour to walk one kilometer in Luoyan Mountain, then here, you may not be able to walk two hundred meters in an hour.

Li Yan waved the tactical scimitar in his hand, constantly chopping and chopping the entangled old vines and broad leaves, almost completely blazing his way.

"Brother Yan, this dense forest is like a spider spirit's silk hole, these vines and roots are even more difficult to deal with than the spider spirit's cobweb."

Tie Qinglan followed behind Li Yan, expressing her opinions and feelings to the dense forest from time to time.

"Try to talk as little as possible and maintain your strength."

Li Yan also felt an unprecedented physical exertion, which was even more primitive than the Amazon jungle.

Moreover, so far, Li Yan has not seen any living creatures, not even mosquitoes.

In this humid and stuffy environment, there is not a single mosquito, which is an absolute warning!

"Brother Yan, do you feel as if we are being targeted?"

Tie Qinglan followed behind Li Yan, and the two of them spent more than half an hour, and they only walked out thirty meters.

In the short rest that stopped, Tie Qinglan's face was a little solemn.

Sometimes, people's intuition is usually surprisingly accurate, and the feeling of being targeted is really too obvious.

"It's not a human, it's something, it's supposed to be a predator in this dense forest."

Li Yan pointed to the ground in front of him as he spoke, and then continued: "The ground here is all mud, and it is a pit when you step on it, but we haven't even seen a mosquito so far, don't you think it's strange?" ”

"Yes, it stands to reason that in this kind of environment, things like snakes, insects, rats, ants, mosquitoes, leeches, etc., should be the favorite."

Tie Qinglan underwent two months of survival training in the jungle, and without even a knife, she was thrown deep into the Amazon jungle.

She has a deep enough understanding of the jungle.

"There is only one possibility for such a situation."

Li Yan paused for a moment when he said this, then glanced at Tie Qinglan, and then the two of them invariably said the same answer.
