After last night's heavy rainstorm, De Ye was exhausted, staring blankly at the drifting boat.

Liu Wei has the blessing of systematic medicine, his physical condition is quite normal, De Ye didn't sleep all night last night, and he is older, even if he is active in the wild all year round, he can't withstand the toss of last night's rainstorm.

The tiredness on his face was palpable.

Liu Wei got up and picked up a long bamboo pole and rowed the boat diagonally across the jungle.

The edge of the jungle has been completely submerged by the river, and it is not easy to find a piece of unsubmerged flat land or high ground in the flat Amazon basin.

But De Ye must find a place to rest.

Liu Wei walked into the jungle on a raft while looking around for a place where he could set up a temporary camp.

The overnight torrential rain turned the jungle upside down, and the branches and leaves of the trees on the ground were withered, and the trees that had not yet taken root were all floating on the water.

The surface of the water is muddy and seemingly calm.

Liu Wei used a bamboo pole to lift the floating objects blocking the road.

The further you go in, the more floats there are.

At a glance, pieces of wood of different sizes, but somewhat evenly distributed, float on the water.

Liu Wei felt a little wrong, and chose to stop and observe first.

Unlike the previous ones, these blocks did not fluctuate due to the current, but remained motionless as if they were fixed to the surface of the water.

De Ye also noticed that something was wrong, and turned around and instructed Liu Wei, "Liu, hold on a little further!"

Liu Wei nodded.

Prop up the raft and go inside.

After walking more than ten meters away, these wooden blocks floating on the water revealed their true colors.

De Ye and Liu Wei's whole body tightened.

They saw the eyes.

A pair of eyes as big as copper bells watched the movement on the water.

"No! Liu, that's too bad, it's a crocodile!" De Ye said excitedly.

Even though he was mentally exhausted, the dangerous predicament constantly stimulated his cranial nerves, forcing him to remain vigilant.

Liu Wei frowned and said solemnly: "Master De, you look at the color of their heads, as well as the protruding big eye sockets, nine times out of ten they are black crocodiles!"

Deye's shoulders suddenly rose up.

Before Liu Wei said the conclusion, he had already made a judgment in his heart, just to calm his emotions, and did not deliberately think about it.

Liu Wei is a professional in animal research, and he can identify animals by their physical characteristics.

The most obvious physical characteristics of the black crocodile are its body color, large eye sockets, and high backbone!

The crocodile in front of you only has its head on the surface, and its color is slightly yellow, which is slightly different from the black crocodile's black body. Black crocodile cubs have some yellow spots on their body color, and these macules will gradually fade with age, and become black all over the body as adults, and the older they get, the darker the color.

Even if you can't tell the crocodile species in front of you by the color of the body surface, its large eye sockets are so remarkable that even ordinary crocodile lovers can tell its identity.

De Ye's mood became more and more nervous.

He knew very well how destructive the black crocodile, the black caiman he had talked about last night, was.

Throughout the Amazon basin, it must be the apex predator at the top.

"Liu, we need to change direction!" De Ye said to Liu Wei.

Liu Wei's face was quite calm, looking at the crocodiles that were about to move, and analyzed, "At present, they are not very interested in us, last night's heavy rainstorm washed many fish in the Amazon River into the flooded jungle, this is an excellent predatory opportunity for black caimans, they are all waiting for the fish to swim past and pack a meal!"

De Ye agreed with Liu Wei's professional analysis, but because of the tension, his perception of this crocodile only stayed on the ferocity, and he said nervously: "Liu, the black caiman is one of the crocodiles that attack humans the most times in the world, second only to the Gulf crocodile and the Nile crocodile, they seem calm now, but you can't guarantee that it will suddenly divert its attention and launch an attack on us."

There are at least ten crocodiles I can see right now, and maybe some of them are lurking in the water, and if they had targeted us, we would have become food for crocodiles today!"

Liu Wei nodded, Deye's analysis was partly correct, but his understanding of the personality and living habits of the black caiman was too one-sided.

"Master De, although the black caiman is notorious for attacking humans, it is not the kind of bad guy who is heinous and has nothing to do.

In the Amazon Basin, including Brazil, Guyana, Colombia and other countries, there are black caimans in distribution, especially in Indian reservations and some primitive tribal gathering areas, the range of black caimans and human ranges overlap very highly.

They are not what you might think, using humans as food and entering areas of human activity to prey on humans.

The contradiction between black caimans and humans mainly manifests itself in two points.

One is the common food, fish, black caiman has a wide food chain, including the same kind, birds, otters, pythons and even forest snakes, etc., but fish are the easiest and most energy-saving predators.

Humans who also live in the Amazon jungle, fish are not only their food, but also an important source of economy.

So there will be a fight between the two over the common food, and the result of the fight is very tragic.

The black caiman belongs to the kind of ruthless character who generally doesn't know how to move and tears the opponent to pieces. ”

"The second reason is reflected in the vigilance of the crocodile itself, which is not only directed against humans, but also against all creatures that make it nervous and oppressive, and in the instinctive reaction of self-defense, it will actively attack each other.

We're stuck where we are, we haven't alarmed them, and we should have no big problems going around on the right. ”

Liu Wei suddenly smiled and said with some excitement, "Master De, as an animal research scholar, I don't want to miss such a good opportunity to communicate with this top predator!"

De Ye's eyes were stunned.

Looking back at Liu Wei, he was smiling and looking a little excited, which was completely different from his current nervous state.

Is it really because I didn't rest last night and was overly nervous?

De Ye thought about it.

He chose to believe Liu Wei's professional analysis, as long as he didn't bother these guys and took a detour from afar, there should be no danger to his life!

"Liu, listen to you!" De Ye can be regarded as handing over his life to Liu Wei.

Liu Wei rowed to the right with the boat according to his own ideas, and gradually approached the black caiman group in a straight line.

Their eyes rested on the black caiman's eyes.

De Ye shook his head, trying to keep his composure, and then looked back at the other side, thinking that nothing would happen.

Liu Wei's rowing movements were small, and the ripples on the surface of the water were insignificant. Don't forget to observe the movement of the crocodile when moving forward, so that you can take emergency measures.

However, what he didn't expect was that not far to the right, there was a group of black caimans floating on the water ready to hunt.

"Liu!" De Ye also observed the group of crocodiles on the right, looked back at Liu Wei, and whispered Liu Wei a little nervously, wanting to ask him what to do now?
