Zheng Ya carried Wang Xiaojun on his back, closed his eyes and breathed, as if he was resting with his eyes closed, but the momentum of the whole person was vaguely shrouded around the kayak, carefully and seriously paying attention to the surrounding environment.

Unlike his companions, Zheng Ya knew that in the river around his kayak, there was a very terrifying, extremely ruthless snake waiting for an opportunity to launch.

Zheng Ya really didn't dare to be careless.

After a while, the kayak continued to move forward, and it had gone far away, without the slightest abnormality, and even the old wolf and the flying wolf slowly relaxed their tense nerves, and the expression on their faces was much better.

But at this time, Zheng Ya, who closed his eyes and breathed and carefully observed the environment, sensed Dong Huanqing's slight inappropriateness, the professor's breathing was rapid, and he seemed to be able to hear his heartbeat not far from him.

If Zheng Ya hadn't been in the state of a great grandmaster at this time, he wouldn't have such a clear perception.

A slight doubt rose in his heart, why was Dong Huanqing so nervous? What did he know? Could it be that he had observed the existence of the forest worm?

With a move in his heart, Zheng Ya opened his eyes leisurely and looked at Dong Huanqing.

At this moment, Dong Huanqing's face was slightly red, staring at the river tightly, his hands kept rubbing, looking nervous and quite excited.

And his eyes seemed to be full of expectation.

Did he see the forest worm? If so, why didn't he have any frightened expressions, and why didn't he warn everyone?

Zheng Ya's heart was full of questions.

At this time, Dong Huanqing suddenly raised his hand and whispered: "Everyone be careful, I have observed an abnormal situation in the Amazon River, and there are big guys in our vicinity." ”

Zheng Ya couldn't help but be slightly stunned, his judgment was wrong again, is Dong Huanqing ready to reveal the information about the infestation of the forest worm to everyone?

The old wolf's body shook slightly, leaned the kayak to the side, and whispered, "What's the matter?"

Dong Huan cleared his hand to the river behind him, lowered his voice and said: "You see, under the river surface, there seems to be an undercurrent surging, I have been observing for a long time, and some unknown monsters have secretly followed us." ”

Zheng Ya looked in the direction specified by Dong Huanqing, and his brows couldn't help frowning slightly.

There may indeed be some problems there, but it will definitely not be the forest snake, Zheng Ya has seen the ruthlessness of the forest snake, there is no doubt that it will never make such a big movement in the water.

Ronaldo lowered his voice and cursed: "Damn, I'm a caiman leather kayak, how can I attract hunters?"

Dong Huanqing rubbed his hands, his eyes were full of excitement and said: "According to my understanding, this is relatively easy to analyze, caimans are powerful, but in the Amazon river, there are not many caimans who are not afraid of the existence, and the big guy in the river behind is likely to be the notorious, Amazon bull shark." ”

Immediately afterwards, Dong Huanqing was very excited to give everyone the knowledge of bull sharks.

The Amazon bull shark, also known as the bull white-eyed shark.

Often dubbed the "wolf of the Amazon river", "human killer", "mysterious river killer", "shipwreck butcher", etc., studies have shown that changes in the underwater environment and geography are enough to cause prey to attack.

According to Dong Huanqing's introduction, the bull shark ranks first among all sharks in terms of bite force.

Adult bull sharks are capable of growing to more than two meters in length and 200 kilograms.

This is really a tough overlord in the river, a fierce existence that is not afraid of caimans at all, and at some point, he has an unusual eye on the team's kayaks.

Dong Huanqing's popular science had just ended, and on the surface of the river, a big fish more than two feet long suddenly skimmed over the river and fled quickly into the river.

Under the lapping of the waves, the kayak involuntarily, up and down, and every member of the team felt that the kayak was a little bumpy.

The bull shark chased out, but before it caught up with the big fish, a giant crocodile suddenly burst out of the river, intercepted it halfway, and put the big fish in its mouth, dripping a pair of cold crocodile tears, dragging the big fish that kept struggling, and sank into the river.

The bull shark chased after it unwillingly, and in the somewhat muddy river, it began to set off huge waves, and it was not clear whether the two big guys were fighting, and they didn't know which one the big fish was swallowed in the end, and after a while, the river was calm.

On the kayak, the team members looked at each other.

Ronaldo, in particular, is now sweating even more, and his mouth keeps muttering: "How is it possible, how is it possible? In the Amazon River, how can there be so many big things, it's over, and it's been targeted by two predators." ”

Zheng Ya actually wanted to tell Ronaldo that compared to the two fierce beasts that had just appeared, there was also the ultimate hunter of the Amazon River hidden in the river, the forest dragon.

The old wolf also frowned at this time and said: "No, it is good that there are dangers in the Amazon River, but these powerful predators often have their own territory, how can they all run to target us?

Gu Tie frowned and said: "Old wolf, the situation is a little wrong, could it be that the opponent has discovered our existence and used a way that we don't know to drive these things over and cut off our retreat, right?"

The green wolf immediately stood up and protested: "Brother Tie, this may just be a coincidence, don't think about the problem so complicated, with my level of concealment, how can it be discovered by the opponent?"

Hearing the conversation of several people, Zheng Ya's heart suddenly moved, his mind suddenly brightened, his head twisted suddenly, Zheng Ya looked at Dong Huanqing with blazing eyes, and asked in a low and clear voice: "Professor Dong, you should know why this is, I think, you need to give us an explanation." ”

Zheng Ya's tone was obviously wrong, and all the members of the team couldn't help but look at Zheng Ya in surprise, and then at Dong Huanqing.

Dong Huanqing's face still had a hint of excitement, and when he saw that everyone was looking at him, he couldn't help grinning, and said softly: "Does this need to be explained? For me, a biologist, if I come to the Amazon to explore, if I can't witness the murderous creatures of the Amazon, wouldn't this trip be in vain, hehehe, yes, yes, this time I actually saw a bull shark and a caiman, if I could catch a few and make a specimen, it would be even more perfect." ”

The old wolf glanced at each other, feeling that this professor was a little abnormal.

Zheng Ya frowned slightly, stretched out his hand, fished out a small stick from the side of the kayak, and said in a deep voice: "If my guess is right, this so-called sonar device should be the culprit that attracted so many predators." ”

Dong Huanqing frowned, and said unhappily: "Zheng Ya, you are very smart, you guessed my scientific research settings, but isn't it just right? Hurry up and put him down, I am still waiting to attract more creatures to facilitate my Amazon scientific expedition this time." ”

Youhe Gu Hongchang shouted angrily: "Problem, the Amazon is in crisis, you actually attract big guys, do you think you have a long life or what?"

Zheng Ya looked at the old wolf.

Ronaldo's complexion changed greatly on the side, and he gritted his teeth and roared: "Dong Huanqing, you are playing with fire, Zheng Ya, well done, quickly, throw this thing to me, the farther away the better." ”

The old wolf stared at Dong Huanqing and said in a low voice, "Professor, what reason are you doing this?"

Dong Huanqing touched his eyes, sat on the kayak, and said in a deep voice: "You are not scholars, you don't understand the importance of studying South American biology, especially the Amazon jungle biology to my country's biology, if it weren't for the Amazon jungle for a long time, I wouldn't have made this trip? Don't look at me with that kind of idiot look, I know what I'm doing......

After a pause, Dong Huanqing continued: "As a scholar, I can show up for science, and I am not afraid of those big monsters in the river, but you are still soldiers, and you are so frightened by a few water monsters that you dare not come out, okay, it's not that serious, a few bull sharks, a few caimans, and I will naturally expel them completely." ”

The old wolf exhaled slightly, and the expressions of the other members of the team also improved slightly, as long as there is a way, then it is easy to say, Dong Huanqing wants to study, then let him be, as long as it does not endanger everyone's safety.
