There are many things in the world. It's just a coincidence. Just like Zhang Ailing said, "There is no step early, and there is no step late. It just happens."

Because the doctor was often attacked by this child, but could not think of a solution, he was very distressed. Just when the doctor was at his wits' end, an unexpected turn of events suddenly occurred.

This is quite a coincidence.

The doctor had a very good friend named Frank Guyton (Charles Darwin, 1822...1911). This Frank was none other than the famous cousin of Darwin, the founder of the theory of evolution.

Frank himself is also a famous anthropologist and explorer. Like his cousin Darwin, he has conducted in-depth research on human evolution.

The doctor and Frank met at an academic conference and hit it off immediately. They talked very enthusiastically and soon became friends who talked about everything.

Once people have unsolvable depression in their hearts, they often confide in good friends. Doctors are no exception. He really doesn't know how to deal with this "weird child" who is growing up. This child is only eleven or twelve years old. With such a strong attack ability, I don’t know what will happen as I grow older.

So, in a long conversation, the doctor told Frank everything about the freaks.

Frank was very shocked after hearing this, because although he was well-informed and had in-depth research on anthropology, he had never heard of such a strange thing.

There is a famous saying that "scholars are as curious as children." Frank was no exception. He was shocked and more curious about these strange things the doctor said. So he asked to go to the doctor's house to see him. See what is so special about the child that this freak developed into.

Before Frank met the "strange child" for the first time, the doctor repeatedly warned him not to get close to the child to avoid being attacked.

Frank agreed on the surface, but he was still doubtful about the doctor's words. Especially after meeting the child, he felt that the doctor's warning was a bit exaggerated. Because the child looked thin and small, even smaller than other children of the same age. Thinner. How could such a child have terrible attack power?

So Frank decided to test it out.

This child was very withdrawn. When he saw Frank and the doctor coming in, he didn't say hello. He just glanced at them expressionlessly, and then continued playing origami by himself.

The doctor did not disturb the child. He tried to make the child feel that this was a normal visit from a friend. Frank also pretended to be nonchalant and walked slowly around the room, looking at the paintings on the wall.

While the doctor was pouring coffee, the child was facing away from Frank. Suddenly, Frank took out a candy bar from his pocket and threw it towards the child from behind.

The reason why he did this was because he heard from the doctor that the child was particularly sensitive to the moving objects around him and could also fight back very quickly. The purpose of throwing the candy was to test whether the doctor said these conditions. true.

But what happened next was obviously beyond Frank's expectation:

The child seemed to have eyes on his back. Before the candy hit him, he turned around suddenly and caught the candy with his hand. Almost at the same time, the child jumped up again at an extremely fast speed. He came over and kicked Frank's calf bone at a very fast speed. All these actions were completed almost instantly. Frank didn't even see it clearly. He only felt a sharp pain in his calf. He knelt on the ground. Then He rolled on the ground in pain.

The doctor who was pouring coffee heard something wrong. When he looked back, he found that his friend was already rolling on the ground holding his legs. He knew that Frank must have been attacked by the child. So, he quickly ran over and took Frank to the ground. He picked it up and took it to his hospital.

After an examination at the hospital, it was discovered that Frank's calf bone was cracked by a kick. He was put in a plaster and lay in the hospital for half a month before he could walk. After this experience, Frank completely believed everything the doctor said.

This incident happened in 1879.

After that, what Frank and the doctor discussed most was how to find the fatal weakness of that "weird kid" so that it would be possible to subdue him.

During this half-month hospitalization, Frank was not idle. His hospital bed and table were all piled with documents. He immersed himself in these piles of documents every day, seriously thinking about all the weird things about this child.

Although it was said that it was a hundred days of "bruising", because Frank's calf bone was only cracked by the kick and not broken yet, the recovery was relatively fast. He was able to walk after half a month.

For ordinary people, after being attacked once, they should have lingering fears and would not easily see the child again. But this Frank is different. He really has an adventurous spirit. Just two days after he came out of the hospital, he asked the doctor again. Take him to see the child.

The doctor knew his good friend's temper and knew he couldn't defeat him, so he had no choice but to agree. However, he specifically told Frank to be careful this time and not to provoke that child again.

Frank had obviously learned the lesson from last time. He just observed the child from a distance and did not dare to stimulate him or get close to him again.

Just like that, Frank went there three or four more times. Each time, he observed the child's every move from a distance. At the same time, he was writing something in his notebook, and his brows were furrowed, as if in deep thought.

The doctor knew that Frank was very knowledgeable, especially in anthropology. He was very eager for his good friend to make a breakthrough as soon as possible, so as to uncover the many mysteries about the child and come up with solutions. Method.

Frank is indeed a first-class expert in this field. His research quickly made progress.

The doctor remembered it very clearly. It was an evening in the autumn of 1879. The doctor was just about to go home from the hospital. Suddenly, Frank sent a servant to invite him over, saying that he had something urgent to see him.

Although the servant didn't know what it was about, based on his understanding of Frank, the doctor could vaguely guess that the reason why Frank was in a hurry to find him was probably about the child... It was most likely that Frank suddenly thought of something. So I couldn't wait to tell him, because during these days, Frank was completely immersed in the research on that child. He even went to the British Museum to borrow a lot of materials a few days ago.

The doctor's guess was indeed correct.

When the doctor came in, Frank shouted to him excitedly like a child: "I know what's going on."

After the two sat down, Frank couldn't wait to tell the doctor the results of his research on the child.

It turns out that the pair of freaks is indeed a strange "atavism"... that is to say, the growth and development process of the pair of freaks condenses millions of years of human development history: they can both A special creature that lives in water and can also live on land;

When they were young, they should be very similar to the earliest ancestors of human beings who lived in the water. Although they can develop into adults in a very short period of time, many internal organs and many body functions are still very different from ordinary people. .

Judging from its initial eyes, skin, and amphibious characteristics, this monster is relatively close to frogs in many aspects. Especially, it is as sensitive to moving objects as a frog. This is even more illustrative. Its connection with frogs.

Now that we know that it has some characteristics similar to frogs, we can figure out how to deal with it.

The doctor could understand most of what Frank said, but he was confused about Frank's final conclusion: "Knowing that it has some characteristics similar to frogs, you can think of ways to deal with it."

Frank did not rush to explain to the doctor. He just smiled mysteriously and took out a metal object from the drawer. This object was as big as a finger and looked very much like a whistle.

Sure enough, Frank put it in his mouth and blew it. But to the doctor's surprise, the "whistle" didn't make any sound. But Frank didn't stop. He still puffed out his cheeks and blew.

The doctor became even more confused. He thought to himself: A whistle that makes no sound. Why are you blowing it?

Just when he was about to ask Frank something, suddenly something strange happened. He saw three cats running over from outside. As if they had heard the call, they ran into the house with clear goals and squatted down obediently. In front of Frank. Then they all looked up at Frank.

Only then did Frank stop. He took three fish from the jar next to him and threw them to the cats. The three cats then took the fish in their mouths and went to the corner next to them to eat.

The doctor was confused by Frank's series of strange actions. He didn't know what Frank was doing. Frank still had a mysterious smile on his face. He didn't say much. He just took a book from the table and handed it to him. The doctor said: "This is a book I published three years ago. All the secrets are in this book."

The doctor took the book with a blank look on his face. He looked at the title and it was "Inquiries into Human Faculty and Its Development". Frank also specially helped the doctor to turn to pages 26-28 of the book and let the doctor read it.

After the doctor finished reading these pages, he suddenly realized what had just happened.

Through these pages, the doctor learned that Frank had studied the range of sounds that humans and other animals can hear. After long-term research, Frank found that the range of sounds that various animals can hear is different; because Sound frequencies are different. Some sounds cannot be heard by humans, but cats can; but dogs may not be able to hear sounds that cats can hear.

The sound of the whistle that Frank blew just now cannot be heard by humans, but cats can.

What's even more amazing is that Frank not only knows the hearing range of different animals, but also knows what frequency of sound will make them extremely uncomfortable and weak.
