Ke Xue: The thief Cao is actually myself

Chapter 490 How can a man say fast! (Please give me a monthly ticket!)

"Could it be that the murderer of Moriya Teiji is actually a woman?"

After looking at everyone, Inspector Megure had a bold guess in his mind.

That is, the murderer of Teiji Moritani is most likely not a man, but a woman.

After all, although with the development of the times and the change of gender concepts, the concepts of men's rings and women's rings have become increasingly blurred, the choice of rings is no longer restricted by gender, but depends more on personal preferences and style.

But generally speaking, few men wear women's rings.

Officer Shiratori pondered for a moment and offered a different opinion, "It could be possible that he was deliberately pretending to be a woman."

Although it is true that rings are divided into men's and women's styles, what if some people like to wear rings that are opposite to their gender?

What if the person in the video was trying to make people mistakenly think he was a woman?

This possibility is not impossible.

Moreover, even he was not sure whether the figure wearing a baseball cap in the video was actually the murderer of Teiji Moritani.

What if the other person just happened to pass by the Rice Flower Cinema?

We must not jump to conclusions until the real murderer is found and brought to justice.

Miwako Sato glanced at Officer Shiratori indifferently and said nothing.

Of course she knew that what Officer Shiratori said was possible.

But she knew even more that the reason why the other party made such a guess was, on the one hand, because there was indeed such a possibility, and on the other hand, because in the other party's heart, he still had doubts about her man!
In other words, in the other person's mind, this suspicion did not completely disappear with the reprimand of Inspector Megure and the "proof" produced by her boyfriend.

She wanted to scold the other person, but Sato Miwako knew very well that with the other person's personality, even if he admitted his mistake on the surface, he would probably still do his own thing as before in private.

Moreover, she didn't want to make a big fuss and cause trouble for her boyfriend and her boss, Inspector Megure.

So, she decisively chose to ignore a certain coral-headed police officer.

Because she didn't want the other person's affairs to affect her and other people's moods.

"Inspector Megure and Officer Shiratori, what you two said is possible to a certain extent, and your ideas have their merits, but they also have loopholes."

Taking in the expressions on their faces, Bai Ye smiled faintly: "After all, judging the murderer's gender based on the style of the ring is a bit too one-sided. Similarly, thinking that the other party is deliberately disguising themselves just because the ring they wear is a female style is also not based on sufficient evidence!"

"If we want to know the murderer's true gender and body, we must start from more aspects, such as other remains at the scene, nearby eyewitnesses, etc...."

"Well... I think what Bai Ye-kun said makes sense..."

At this time, Takagi Wataru, who had been standing by and observing silently, scratched his head and glanced at Officer Shiratori cautiously, looking a little hesitant. "Officer Shiratori, I think... maybe we can investigate the surveillance cameras around the cinema again, or look for other eyewitnesses. Maybe we can find some new details and find more clues about the man in the cap."

To be honest, even he, an honest man, felt that Officer Shiratori was a little too irrational today.

Sato Miwako nodded in agreement. "Officer Takagi's suggestion is good. If we can know the walking posture of the blurry person wearing a peaked cap, or the size of his footprints, then it will be easier for us to determine whether he is a man or a woman."

People have different walking postures: some jump up and down, some swing left and right, some hold their chests out and their heads high, some lower their heads and bend their waists, some have their feet in a wide position (with an abduction angle of more than 20 degrees, commonly known as external eight characters or crooked eight characters), some have their feet abducted in a medium or small position, and some walk in a straight line or asymmetrically (the left and right steps are quite different and there is no symmetry).

Moreover, there are differences in walking postures between men and women. Women swing their hips and rotate their waists when they walk, while men's knees move more clumsily when they walk. This is a natural physiological difference.

——Male, tall, steady, as solid as a mountain. Their feet are long and wide, with upright toe bones, high and narrow pelvis, and strong waist. Because they have less fat, clear muscle lines, and hip circumference smaller than shoulder circumference, their center of gravity is high when walking, their stride is wide, and their jumping ability is strong. This walking style leaves a unique mark on the footprints: the footprints are long and wide, the rising and falling steps are powerful, and they are often accompanied by tread marks and kick marks. The indentations vary in depth and are mostly biased to the outside.

Women, on the other hand, have graceful postures and walk as lightly as flowing water. They are relatively short in height, with narrow and short feet, soft arches, and slender toe bones. Their pelvis is low and wide, and their waist is narrow, like a willow tree. Because of the even distribution of fat and the fact that their hip circumference is larger than their shoulder circumference, they have a low center of gravity when walking, small strides, and excellent stability. This walking posture also leaves a unique mark on their footprints: the footprints are narrow and short, the rise and fall of the steps are balanced, the indentations are evenly distributed, and the arch pressure is wide.

In addition, it is also possible to identify whether a person is walking normally or in disguise, or walking with weight or without hands.

This is because each person's walking posture is reflected in different pressure points and degrees of wear on different parts of the foot.

For example, most men with average build walk with their feet in a middle position. Overweight people tend to swing their feet left and right when walking, with their abducted feet in a wide position. Thin people tend to walk with a small position. People who lift and put their feet down quickly and decisively are likely to have had military experience.

For shoe prints with heavy wear and tear symmetrically on the outer edges of the footprints, it is more likely that they were left by a person with bow legs. For men who walk with asymmetrical steps, there may be disease in their leg joints.

For women, the small-legged and straight-walking steps are more common, but asymmetrical steps are also common. This is because the bones and structures of men and women are different, so men and women have their own different characteristics. A person's walking posture is also related to genetics or personal experience (such as military service).

After hearing her words, Officer Megure, Officer Shiratori and others looked at each other and decided to do as Officer Takagi suggested.

But before they turned around and left, Bai Ye paused for a moment and interrupted their actions, "In fact... we don't need to investigate the Rice Flower Cinema to find out the true gender of the man in the baseball cap."

Officer Megure was slightly stunned. "Hmm? Brother Bai Ye, did you find something?"

"Bai Ye... do you know whether that person is a man or a woman?" Sato Miwako's eyes lit up.

In their expectation, Bai Ye raised his eyebrows slightly, "Of course... Just as Miwako and Inspector Megure guessed, the person wearing a baseball cap and a blurry figure is actually a woman!"

When he said this, Bai Ye paused and looked at the computer beside him. "As for the evidence, it's in that video."

As he spoke, he didn't pay attention to the expressions on other people's faces. He just stretched out his hand and tapped a spot on the screen: "Look, from this angle, if you look carefully, you can see a light shining near her ears. If I'm not mistaken, that should be the light from the earrings."

"Also, from here, we can clearly see that there is no Adam's apple on his neck."

"Based on whether he wears a female ring, earrings, and whether he has an Adam's apple, we can determine that his true gender should be female!"

After listening to Bai Ye's reasoning and analysis, everyone couldn't help but be stunned.

You have to know that the entire video is only five seconds long, and the suspect is not standing still. It is almost impossible to find clues in such a short time.

However, the scene that almost flashed by was captured by Bai Ye, and he also captured so much important information. It was really incredible.

"Brother Bai Ye, if I remember correctly, the entire content of this video should only be five or six seconds long, right? How did you find so many important clues after only watching it once?"

Inspector Megure looked at Bai Ye in shock, his eyes completely dull.

Although he had long known that his brother was extraordinary, he really did not expect that the other party could be so extraordinary!

You know, to analyze so much important information in just a few seconds, such an outrageous thing, even a high school detective who is hailed as the "savior of the Japanese police" and the "Sherlock Holmes of the Heisei era" may not be able to do it!

"This is unrealistic and impossible!"

After taking a deep look at Bai Ye, Officer Shiratori frowned slightly.

"impossible?"

As soon as these words came out, they were like a stone hitting the hearts of all the police officers in the third search department, causing ripples in their hearts.

"Officer Shiratori, is there anything impossible about this?"

Inspector Megure frowned, looking serious.

Although he also felt that this kind of thing was a little unbelievable, there are all kinds of strange things in the world. What if Bai Ye is that kind of extraordinary person with particularly sharp observation skills!
However, a certain Coral Head police officer insisted that such a thing was impossible.

Considering the other party's previous behavior of deliberately targeting his brother Baiye, Inspector Megure felt that this subordinate of his was probably not honest again and wanted to make trouble for Baiye again.

Officer Shiratori did not answer his question directly. Instead, he walked to the computer with a serious expression, then pulled the progress bar of the video back to the front and clicked the mouse to play the scene again.

"Officer Shiratori, what exactly do you want to say?"

Watching his actions, Inspector Megure frowned even more tightly, his face full of confusion and doubt.

What does this mean to his subordinate?
"As a visual organ, the main function of the eye is naturally to form an image. After taking in external information, the eye will automatically convert this information into images, and then transmit it to the brain in the form of images. Then our brain can "decode" these images. After analysis and processing, the brain will direct other organs of the body to respond. In other words, seeing something requires a process and a reaction time."

When light enters the eye, it is refracted and adjusted by a series of eye structures such as the cornea and lens, and finally forms an image on the retina.

The retina is like the photosensitive film in a camera, responsible for photosensitivity and imaging. When you look at things, the image falls on the retina through the refractive system. There are 1.1 to 1.3 million rod cells and 600 to 700 million cone cells on the retina. These cells are divided into three layers, namely photoreceptor cells, bipolar cells, and ganglion cells.

Photoreceptor cells convert light quantum energy into electrical signals, that is, light stimulation becomes the hyperpolarization of the membrane potential of the receptor cells. Bipolar cells are responsible for classifying and processing these electrical signals, and transmitting the processed signals to ganglion cells through chemical synapses. Ganglion cells transmit these classified electrical signals to the brain to form the final image. Ganglion cells are the only cells that can encode the visual information processed by the retina into nerve impulses and transmit them to the brain.

Simply put, photoreceptor cells convert light into electrical signals, bipolar cells are responsible for processing these electrical signals, and ganglion cells are responsible for transmitting these signals.

However, because the ganglion cells are on the outermost side of the retina and the photoreceptor cells are on the innermost side, due to this abnormal design, when light enters the pupil, it must first pass through the ganglion cells and bipolar cells before reaching the photoreceptor cells.

And because the ganglion cells are located on the outermost side, but they need to send the processed signals to the brain, so they have to make a hole in the bipolar cells and ganglion cells, and then pass the nerve fibers through them, that is, go back through the eyeball and then around the brain.

Such an operation undoubtedly requires a process to see something, and the person who sees it also needs a certain amount of time to react.

But Bai Ye actually managed to identify all the features of the man in the baseball cap in the video that flashed by in just a few seconds.

This is really too unbelievable.

It's so incredible that one can't help but wonder, is all this really possible?
It's so incredible that one can't help but wonder if Bai Ye had seen this video before, so he could analyze so many things after watching it for the 'first time'!
Staring at Bai Ye intently, Officer Bai Niao's eyes flickered with suspicion, "The video was only five or six seconds long, and all the images flashed by, but Mr. Bai Ye was able to see the subtle details of the characters in it so carefully..."

At this point, Officer Shiratori paused, with a meaningful look on his face, "Mr. Bai Ye, don't you think your reaction speed is a little too fast?"
