Really people?

Although they were already prepared, after hearing Xu Ye's personal confirmation, the audience was still a little surprised.

Although they have seen a lot of bones in so many live broadcasts, all of them are from animals, and this is the first time they have seen human bones in the wild, and it is only a small piece, which is even more terrifying.

"This is certainly not killed by pythons, the number of pythons in South America is very rare, most of them are alien species, here is dominated by the python family, and can have the ability to eat people, only the anacondas, they only live in the water, and the amount of food is amazing. ”

"An adult anaconda needs to eat about three or four large dog-level food every month, and in addition to poisonous snakes, there are only some hares, seabirds, rodents and insects on Viper Island, which cannot meet its growth conditions at all!"

Chen Xu directly vetoed the "python theory" in the barrage.

The audience didn't understand, since it wasn't eaten by pythons, why only half of the upper jaws?

You know, even if you are bitten to death by a poisonous snake or killed by someone else, you have to keep a whole corpse, at least it should be a skull!

He pinched this piece of tooth and bone, looked at it carefully for a long time, and finally guessed:

"The reason for the incomplete bones is probably because of decay, the high temperature and humidity in the tropical rainforest area, it is easy to breed putrefactive bacteria, which will accelerate the decay of the corpse, plus there are many insects here, some carnivorous insects will destroy the bones. ”

"Under normal circumstances, it takes hundreds of years for a skeleton to decompose naturally, it will be extended in the northern region, and it will shrink in the tropics.

"Since the tooth is the hardest part of the body, it is difficult to burn it even if it is cremated at high temperatures, so the most difficult thing to decompose is the tooth, but the appearance of this tooth bone has been worn out quite badly, and there are even many breaks, so it ......."

Without waiting for Chen Xu to finish his final conclusion, the audience directly posted it on the barrage, this tooth bone is likely to come from the Guarani warriors who were trapped in the torrential rain on Viper Island.

"That's right, that's what I thought!"

After Chen Xu put his teeth down, he immediately took out the metal detector from his backpack, "Let's search around, maybe there will be new discoveries!"

So, he centered on the location of the tooth and expanded it outward in a circle, and began a carpet search.

In a few moments, he was more than ten meters north when he heard the sound of a metal probe.

Chen Xu swayed from side to side while observing the beam intensity on the monitor.

Finally, he stopped on a barren grass.

"The machine shows that the signal here is the strongest, let's dig and see!"

As he spoke, Chen Xu squatted down.

Instead of using a sapper shovel, he dug by hand, because the sapper shovel was made of a new type of alloy steel, which was very hard.

If there were really 16th-century iron tools buried underneath, the skin would have become brittle after such a long period of corrosion, and he was afraid that this shovel would destroy the clues.

Dozens of seconds later, Chen Xu found a "small iron rod" in the pit.

After carefully cleaning off the soil, what appeared was the shape of an iron square nail of about 10 centimeters.

Chen Xu observed carefully for a moment, "This square nail is estimated to have been buried for a long time, and a layer of brick-red slurry has formed on the surface, which should be mixed with the soil." ”

"Moreover, it should not come from the tower, because the age and texture are not correct, and the tower uses reinforced concrete concrete technology, which will never be fixed with this ancient square nail, which is generally used with wood. ”

The meaning of this sentence is already very obvious, this square nail must have been left behind by the Guarani warriors when they hid their treasure!

Another new clue.

On top of that, it was also found on the treasure route estimated by Chen Xu.

"It seems that we are looking in the right direction. ”

Chen Xu grinned, the discovery of the ancient square nail undoubtedly increased his confidence.

Next, he continued to use the metal detector to look around again.

Unfortunately, nothing new has been discovered.

However, with this square nail as a clue, it is enough.

After three o'clock in the afternoon in Brazil, the sun began to set in the west, and the weather finally became less hot.

But in the same way, all snakes no longer have to hide in the shade of trees and crevices in stones.

Along the way, Chen Xu encountered three more island spearhead pitters, one of which was lying on the ground.

Thanks to his sharp eyes, he bypassed it after discovering it in advance, otherwise, it would inevitably be another struggle.

In this way, he searched for more than a hundred meters.

At this time, a huge black hole suddenly appeared in front of him.

Chen Xu's face was overjoyed, "The cave has finally appeared!"

There are caves, and they are large caves, which means that there is a chance that there will be Inca gold treasures buried inside!

So, as he was careful, he quickened his speed, and after drilling through the trunks of a few rotting trees, he finally came to the side of the hole.

"This is the real cave!"

Chen Xu looked up at the whole picture of the cave entrance.

The cave in front of him was much larger than all the caves Chen Xu had discovered before, at least more than ten meters wide and more than two meters high, and it was pitch black inside, which should have been naturally formed by the movement and fragmentation of the mountain system.

Above it was a hill, covered with bushes and grass, and many vines hung down the hill and blocked the entrance of the cave, like a curtain, which also added a lot of mystery to the cave.

Chen Xu first tentatively walked into the edge of the cave and smelled it, but there was no strange smell, and then he looked at the vicinity of the cave with confidence.

And at this moment, next to the corner of the stone wall on the left side of the cave entrance, a huge, pot-like pit rock appeared in his sight.

He looked closer, and there was a large amount of black powder in the recessed pit, and there was also a lot of it around the rock.

Chen Xu gently wiped it with his hand, put it in front of his nose and sniffed it, pinched it again, and after analyzing it for a while, he frowned and said, "It's charcoal powder......

Then, he looked up at the rock wall above the rock, and there were also blackened marks.

"There are charcoal burnt marks on this rock, it looks like someone has camped here, and the blackened marks on the rock wall will be wiped off, indicating that it will not be too long!"

His words, like a bombshell, frightened all the viewers in the live broadcast room.

What the?

Is there anyone else on this island?

Chen Xu also frowned, staring down at this camping trace and pondering.

And at this moment, above his head, that is, on the hill at the entrance of the cave, there was a sudden "click" sound.
