After winning the prize, the whole network begged me to live broadcast the pastoral pension

Professor Chen saw the little Internet celebrity in the live video bravely getting close to the great white shark.

The great white shark was at her mercy like a pet.

Is this little Internet celebrity an animal trainer?

Professor Chen suddenly became a little interested in the live broadcast.

Gan Tian is still answering questions from netizens.

A netizen mentioned the Lawrence ampulla of the great white shark.

Great white sharks have extremely high sensitivity and can sense changes in seawater to find prey. Here we have to mention a skin sensor called Lawrence's ampulla, which is common to all sharks.

In the dark seabed, the sensory organs of sharks are malfunctioning, and Lawrence's ampulla is like a detector, which emits electromagnetic waves anytime and anywhere to monitor the weak currents around it.

It helps great white sharks sense the weak electrical pulses in the water and sense the Earth's magnetic field, helping them navigate the ocean.

How powerful is this Lawrence ampulla?
Research by scientists has shown that great white sharks can even feel pulses of 1/10 billion volts in seawater.

Professor Chen's research direction is to imitate the shark's "Lawrence Ampulla", and study the technology of human physiological signal perception, but the research in hand has never found a breakthrough.

Professor Chen put his phone on the table and continued to do his own thing. He hadn't yet counted on a small Internet celebrity to provide him with ideas. A small Internet celebrity probably didn't even know what Lawrence's ampulla was.

Seeing the questions raised by netizens, Gan Tian began to introduce Lawrence's ampulla and talked freely.

"Speaking of Lawrence's ampulla, for example, it's like our sixth sense. In the deep sea, sharks hunt through their eyes, smell, hearing, taste organs and sixth sense. There are many small organs scattered around the shark's mouth. Kong, it looks like some beard stubble from a distance, everyone, it’s here.”

Gan Tian said while swimming to the mouth of the great white shark, looking for those small holes like stubble, so that the netizens in the live broadcast room can see clearly at a close distance.

Then, continue to introduce: "If you observe with a microscope, you will find that there are many balloon-like structures under these small holes, which are the Ampulla of Lawrence mentioned by netizens."

When Professor Chen heard her words, he couldn't help but turn his eyes to the live broadcast room again. This time he looked carefully, and couldn't move his eyes away. He followed the camera without blinking, and the more he watched, the more interested he became.

Gan Tian said: "In reality, if you really encounter a great white shark, attacking the Lawrence ampulla of the great white shark may be a better way to escape. We can give this place a fist, because there are a lot of electronic receptors here. Our An attack will destroy its sensory system, allowing it to flee instinctively."

Netizens on land thought it was very interesting.

The number of people in the live broadcast room is increasing...

Originally, there were only more than 300 million people, but now it has quickly increased to more than 1000 million people. They are all people who watched it in the live broadcast room and found it interesting, and spread word of mouth.

There are also some who came in just to complain about her, but ended up winning after they came in, and couldn't bear to leave again.

There are even some oceanographic researchers like Professor Chen, who were recommended by others. At first, they didn't like her at all, thinking that she was just a sensationalist, but they didn't leave the live broadcast room, and even wanted to contact her. to further their research by coming into contact with live great white sharks.

"And now to the last question."

Zhou Ran chose the last question and asked: "A netizen asked, does a drop of blood a few miles away really attract sharks? Can you do an experiment so that everyone can experience it with their own eyes?"

Gan Tian smiled: "This question, I remember that a UP owner once did an experiment. He used four surfboards, and placed devices containing human urine, cow blood, fish oil and urine on the surfboards. These devices have A remote receiving system, when the surfboards arrive at the designated positions, Mark can turn on the device through the remote control without disturbing the sharks in the distance, and then the blood, sea water and urine will slowly drip into the sea .”

"Four sharks were attracted to the surfboards filled with fish oil, 4 sharks were attracted to the surfboards filled with cow's blood and 41 sharks were attracted to the surfboards filled with seawater and urine after the drip device was in operation for a period of time. Then there is not a single shark. Through this experiment, we have seen two truths: first, peeing in the sea does not attract sharks; second, blood does attract sharks."

"In order to further understand how much blood can attract sharks, Mark conducted the next experiment. In this experiment, Marco used two surfboards with two bags of human blood on them. However, the two bags of human blood A control device for injecting a drop of blood in 1 minute and a drop of blood in 4 minutes was respectively installed."

"These two surfboards were still placed in the shark-infested position, and it was found that there were no sharks near the two surfboards. It can be seen that the shark's ability to perceive this slow and continuous bleeding is relatively poor, and Not to mention a few kilometers away, even within tens of meters, they can't sense the presence of blood at all."

Netizens in the live broadcast room booed: "Ah, I don't want to watch other people do experiments, but I just want to watch you do experiments."

"Let's do it, let's do it, let's do an experiment and let us all see for ourselves, can this vengeful shark smell a drop of blood from a few kilometers away?"

"I want to see."

"I want to see too."

Kindness is hard to persuade, Gan Tian is free anyway: "Okay then, I will personally do an experiment for everyone."

In the next hour or so, Gantian was doing experiments in the live broadcast room. She returned to the yacht and said to the shark of gratitude: "Let's play hide-and-seek. I will hide a few kilometers away. Come find me."

The repaying shark made a shark's unique cry, as if it understood it, and was responding to her.

Then the yacht drove away.

The shark did not catch up.

Only a few drones followed the shark, watched every move of the great white shark, and transmitted the pictures to the live broadcast room.

The live broadcast room became two split screens, one screen stared at the great white shark, and the other screen stared at Gan Tian who left on a yacht.

When the yacht was about one kilometer away, Gan Tian cut her finger and dripped a drop of blood into the sea to see if the great white shark could sense where she was?
Erudite stopped Gan Tian's movement, stretched out his hand, and said, "Sister, it hurts, use my blood."

"It's okay, I don't hurt."

"No, it hurts!" Brother Licking Dog insisted.

Gan Tian thought about it and didn't refuse.

She handed the fruit knife to Erudite.

The erudite cut his finger, and without blinking, a few drops of blood fell into the sea water.

Gan Tian said: "Now we are one kilometer away from the great white shark in a straight line. Whether the great white shark can find it by smelling the blood, we will wait and see."
