Chen Xu squinted, looked up at a crooked-necked tree growing out of the crack in the stone, and pointed: "This bird should have been attacked and killed while weaving its nest, you see, there are still traces of unfinished nests on it." ”

Sure enough, at the fork of the crooked-necked tree, there was a small half bird's nest made of dirt and branches.

"I'm not scared of the number of venomous snakes, but I'm curious about why these vipers spit out the carcass without waiting for the carcass to be digested after they have gone to great lengths to kill the animal, and there are two more cases. ”

"I remember when I was in Guatemala, I used to say that the reason why poisonous snakes ruminate, when digesting food, is one of the weakest times for them, so once snakes encounter sudden danger, they will not hesitate to regurgitate their food, in order to maintain a high fighting ability. ”

"In that case, what exactly do these venomous snakes encounter that will cause them to regurgitate their food......

I have to say that Chen Xu's words successfully seduce the curiosity of the audience.

In particular, once the audience already knows that there are only venomous snakes on the island, they have a strong sense of anticipation for any unknown creatures that may appear.

Moreover, listening to the meaning of Xu Ye's words, if it is really a creature, it should be more powerful than a poisonous snake!

After turning a big corner, Chen Xu finally came to the cave he had seen on the ridge before.

When he looked up, he was almost surrounded by boulders and trees, and it looked like the mouth of a huge well, which was the "source" of the coin-sized black dot he saw at the bottom of the mountain.

Afterwards, Chen Xu began to observe the entrance of the cave again.

The entrance of the cave is in the shape of a huge obtuse triangle, which must be more than ten meters wide, and the audience can faintly hear a few "woo" sounds, like ghosts crying.

He explained: "This should be the sound of the wind, the wind at the entrance of the cave is so loud, it means that the cave ** is not completely closed, and there is gas circulation inside." ”

"This is good news, there are gas circulation caves, the air should be cleaner, and the probability of germs and toxic gases will be greatly reduced!"

However, Chen Xu still used the surrounding materials to make a torch, which was mainly used for lighting.

After everything was ready, he carried his equipment on his back, a torch in one hand, and a metal detector in the other, and cautiously walked into the cave.

As soon as he entered, the orange fire shone on a huge spider on the rock wall, which belonged to a large cave spider, highly venomous, and very ferocious.

Not only that, but after a few steps, another big spider lay on the top of the rock wall, less than a dozen centimeters away from Chen Xu.

He swallowed and spitted at the mouth, and said softly: "It seems that there are a lot of poisonous spiders in here, and arthropods are also one of the favorite of poisonous snakes, and the combination of these two is enough to double the danger of this cave!"

If they hadn't seen the man who had been bitten by the island's spearhead pit pit in the morning, the audience might not have felt much.

But after seeing with their own eyes the tragic situation that his life was worse than death, they knew how dangerous the environment Xu Ye was experiencing now was!

Along the way, Chen Xu didn't find any special symbols.

Turning into the next corner, two passages suddenly appeared in front of me, one of which was pitch black, while the other was a faint glow, and it looked like it was probably an exit or something.

He did not hesitate to choose the pitch-black one, and finally found such a large cave, of course he had to go all the way to the depths until he found the gold treasure of the Incas.

However, to everyone's surprise, it was not.

Not long after Chen Xu walked into the pitch-black passage, a rock wall suddenly appeared in front of him.

That is, it's a dead end!

He looked at the rock wall with a stunned expression, and subconsciously muttered, "Impossible, the internal space of this cave is so large, how can it be so short? This is not at all in line with common sense!"

The audience was also a little disappointed.

Because of the foreshadowing: poisonous snakes, ruminant corpses, unknown dangers, poisonous spiders, they are full of this cave.

And now, it's as simple as that?

Helpless, Chen Xu had no choice, just thought he was unlucky.

So, he withdrew from the dead end and walked towards another lighted passage.

Half a minute later, Chen Xu successfully passed through the passage, and he thought that he would walk out of the cave, but when he looked up, another huge hole appeared in front of him!

"This ......"

He hesitated, and walked into the cave again.

More than ten minutes later, he walked out of this hole**, and found two new holes at the same time!

"Oh my God, there are so many caves here, it's like a labyrinth!"

"The road idiot said that he couldn't tell the direction at all!"

"Set up a flag, the treasure is definitely in it, I can't find it, I'll broadcast the Japanese electric fan, fifth gear!"

"Sit back and wait for the live broadcast of the Japanese electric fan!"

Here, Chen Xu's face was also surprised for a long time, and then, he said with a little seriousness: "This is really incredible, what we found is not a cave, but a very large and complex cave system. ”

"It's no wonder that this hill is made up of boulders, and under the natural changes, geological movements, heavy rains, and flash floods will form many natural caves, and over time, when these caves accumulate more and more and are too close to each other, it is easy to form a system of interconnected caves. ”

"Latin America has the most complex cave system in the world, and these complex cave structures are often connected by a network of passages that stretch for miles, which is very dangerous, and if you are not careful, you can get lost here. ”

"Unstable rocks can collapse at any time, and due to the complex cave system, which is a perfect natural labyrinth of concealment and danger, this kind of place has been the best place to bury treasure for centuries!"

"So, some viewers are right, the Inca gold treasure buried here may be very large!"

After speaking, Chen Xu squatted down, picked up three pieces of gravel, formed them into a triangle, and arranged them on the edge of the hole.

"The cave system is very complex and it doesn't see the light of day, so it's easy to get disoriented, so I had to make some markings to sign back the way I came. ”

It's a simple, but very effective method, but it's hard for the average person to notice it.

Twenty minutes later, Chen Xu walked out of a cave again.

And the next moment, in front of him, there were five black holes!

"Damn! It's hard to choose!"

"At such a critical moment, we must resort to the Dafa of 'one bean, no pulling'!"

"The phrase 'a bean' really brings back memories to me!"71
