The Natal Shark Commission is one of the world's most authoritative scientific research institutes, located in Natal, Brazil, and is also the most comprehensive research institute on freshwater sharks, that is, bull sharks.

Immediately after the broadcast of Brazil's Globo TV "Deep Tour", Box, a scientist from the Natal Shark Commission, organized a scientific expedition team to Liu Wei's waters.

The media that were originally waiting to interview Liu Wei and De Ye in Santarém also rushed to the scene after getting the new news.

Nothing is more controversial than documenting Liu Wei's expedition on the spot!

Liu Wei and Deye reacted quickly, jumped into the river, relied on their strong bodies to fight against the turbulent river, and finally landed safely.

De Ye propped his hands on the soft sand, breathed slowly, stared at the river with his eyes, and the bull shark was nowhere to be seen.

"Liu, is it over?" asked Deye.

"Master De, it's just the beginning!" , Liu Wei raised his head and gestured to the helicopter overhead, "Now that the audience across Brazil is looking at us, isn't it boring to end like this?"

De Ye shook his head and smiled, he had already guessed what Liu Wei was going to do?

"We need a boat!" De Ye looked at the sinking wooden boat and said.

Liu Wei nodded.

If you want to catch a bull shark in the wide water, you can't do without a boat, and you need a powerful speedboat.

"Master De, look, what are you talking about?" Liu Wei pointed to the speedboat road running in the middle of the river.

De Ye got up and took off his shirt, revealing his strong muscles, twisted the river-soaked shirt with both hands, and then put the shirt on his shoulders and stretched out his hand towards Liu Wei, "Come on, man, finish the last vote!"

Liu Wei took Deye's hand and stood up.

Ten minutes later, the speedboat stopped on the shore, and a middle-aged man in a white shirt with round-framed eyes hurriedly got off the splint and walked in front of Liu Wei, "Liu, are you okay?"

"It's fine!" Liu Wei smiled and asked, "Who are you?"

"We are researchers at the Natal Shark Commission, and when we learned that bull sharks had appeared in the main channel of the Amazon River, I rushed to the scene with a research team," the man said.

Liu, I've seen the video of you going to Australia to fish for great white sharks, and I admire you!

Just call me Box!"

"Hello, Box, thank you for your support!" Liu Wei stretched out his hand and said.

Box looked back at the water and said straight to the point, "Liu, we also spotted a bull shark in the main channel of the Amazon River last month, and we tried to catch a newly grown bull shark, which is not very large, but it is a male bull shark!"

The tone of his voice was a little confused.

"What happened to the male bull shark?" De Ye asked puzzled.

"Generally speaking, the majority of freshwater bull sharks are adult females and juveniles, with the adult females swimming to freshwater rivers to give birth, and the calves spending their most vulnerable stages in freshwater, swimming to the sea around four to five years old," Liu explains.

When I was a child, in order to avoid predators and competitors in the sea, the bull shark would live in freshwater with no threat, until it reached adulthood, reached maturity in all aspects of its body, and had strong predatory skills, and then returned to the sea to compete.

Of all shark species, only the bull shark can and can do so, greatly improving its ability to survive.

It's a very intelligent shark!"

Box nodded, and then Liu Wei said, "When it comes to freshwater, the bull shark will be more short-tempered, which is why it often attacks humans. ”

Liu Wei guessed: "Box, so you think there has been a phenomenon of adult male bull shark swarming in the Amazon River?"

Box nodded, "From the observation and research in the last few months, it has been found that this is possible, so we need more observation targets!"

Liu, the bull shark that attacked you is bigger than the bull shark we caught before, so I need your help.

We need to determine its gender, put on a GPS chip, and watch its path!"

Liu Wei smiled: "If you don't come, I'm ready to go into the water to catch it, the audience in the live broadcast room wants to see it!"

Box asked, "Are you going to use the fishing method this time?"

Liu Wei looked at the surface of the river and shook his head, "Although it is not yet possible to deduce why there are a large number of male bull sharks gathered in the Amazon river?"

But one thing is for sure, the Amazon River is able to provide them with an abundance of food, and they are not short of food here, so the bait is not very tempting for them!"

"What do you want to do?" asked Box as he looked at Liu Wei.

Liu Wei smiled: "Maybe it needs something that can make it more exciting, such as people!"

The Boxs expedition team was taken aback.

De Ye asked anxiously: "Liu, do you want to ...... again?"

Liu Wei nodded, "I jumped into the river to tempt it, if it appeared, it would definitely attack me, before the bull shark was sure to bite the target, it would definitely hit the target with its body, and when it crashed into me, it was an opportunity!"

After listening to Liu Wei's plan, Box fell silent.

Of course, he knew the danger of Liu Wei's plan, but his desire to study this bull shark was very strong, and then he thought of Liu Wei's previous scene of controlling various dangerous creatures, so he decided to believe Liu Wei once.

"Liu, what do you need to tell us? I'll prepare it right away!" Box asked.

Liu Wei asked, "Is there a fish hook?"

"Yes!"

Boxes came aboard and pulled out a hook more than a meter long, which was guaranteed to keep large fish under control.

"OK!" Liu Wei gestured, "Let's go!"

As soon as they boarded the speedboat, several media rushed to the scene to debug the equipment and shoot the scene.

De Ye asked, "Box, did you arrange it?"

Box shook his head and said, "I don't really like medium-form work!"

De Ye instantly understood, smiled and waved his hand at the media.

There is a helicopter hovering overhead, the whole process is live, and there are media shots on the shore, I have to say that the attention of this finale is very high.

Liu Wei didn't have time to pay attention to his media friends, he was now only thinking about catching the bull shark.

Put on the diving live broadcast equipment provided by the system, hold the fish hook in your hand, and tie the diving rope, "Brothers, take you into the water today to catch sharks!"

After saying that, he jumped into the water.

Liu Wei's body did not swim, floating down the river, and Box instructed the speedboat driver to drive to the middle of the river.

De Ye determined the direction in which they were attacked by the bull shark, and Box relied on his expertise to analyze the range of the bull shark.

The speedboat dragged Liu Wei, the humanoid bait, forward.

Liu Wei himself observed the bull shark in the water.

"Statistics show that the bull shark attacks humans the most often happens to swimmers, I remember the last time I caught a great white shark, I told you that the great white shark will see swimmers as its favorite prey fur seal, similarly, the bull shark will also have such a visual error, and at the same time its strong curiosity and irritable personality will definitely prompt it to attack me!"
