"First mistake."

"After you knocked the deceased unconscious, you should have thrown him off the cliff, but for the sake of safety, you injected him with tetrodotoxin, making the otherwise difficult case simple and straightforward."

"I'm afraid you think that if you throw it into the sea, you can destroy the corpse and destroy all traces and everything will be fine..."

Sakaki shook his head regretfully:

"This leads to the second and third mistakes."

"Killing people first, and then throwing the corpse, will make the corpse have no seawater in the chest, and it will float not long after entering the water....."

"And you didn't observe the tide time, and when you left the body, it was the last stage of low tide, which caused the body to wash up on the beach."

In the end, the faces of the three of Kuroiwa Chenji were extremely ugly.

Sakaki Cheng didn't break it, they really didn't expect that there were so many ways to kill people and throw corpses.

Wrong...

In the final analysis, it is also the relationship between them who killed the wrong person.

If it was Makoto Sakaki who died last night, would there still be so much trouble today?

The answer is no.

Because they missed Conan.

This kid isn't an idle man!

"Ahem...."

Kuroiwa touched his nose again:

"Mr. Sakaki, although you are a great detective, you can't just wronged people!"

"What evidence do you have to say that we are prisoners?"

Asai Narumi clenched his fists, gritted his teeth, and his angry body trembled.

Behind her, the old policeman stationed at the station stared at her back with an expressionless face.

Makoto noticed the abnormality of Narumi Asai and was a little surprised in his heart.

But....

The top priority is to solve the case in front of us first, and then hurry back to Tokyo.

"Everyone has heard the story of Pinocchio."

"There's a lot to be said about this story."

"Physiologically, when a person is lying, the body releases a chemical called catecholamines."

In front of everyone, Sakaki Cheng talked eloquently:

"This chemical causes the structure inside the liar's nose to swell, and at the same time..."

"When a person lies, his psychological pressure increases dramatically, and his blood pressure rises rapidly."

Standing in the center, Sakaki Cheng seemed to be strolling leisurely, and circled around the three of Kuroiwa Chenji, secretly exerting psychological pressure.

"When blood pressure rises, the nose enlarges, creating the so-called Pinocchio big nose effect,"

"And, when the nose swells, the nerve endings feel a slight tingling, so...."

"The liar will involuntarily touch his nose quickly with his hand to relieve the itching of the nose."

"Chief Heiyan Village, can you tell everyone why you touched your nose so much just now?"

The fishermen listened to Sakaki's reasoning show, their faces turned red with excitement, where could they care about anything else, they only hoped that Kuroiwa Tatsuji would confess later.

And Kuroiwa Tatsuji did the same.

The sudden increase in psychological pressure caused his nose to itch again.

But I can't reach out to scratch it, I can only pull the collar, scratch my ears and cheeks, and be very anxious.

As a result, Sakaki Cheng questioned his action again:

"According to scientific studies."

"When a person lies, in addition to what I just said, there is a slight tingling or burning sensation in the sensitive tissues of the face and neck."

"In order to subside this feeling, the liar will often unconsciously pull the collar or make other movements in an attempt to subside the burning sensation."

"Chief Kuroiwa, you...."

"That's it!"

Kuroiwa Tatsuji couldn't stand it.

He felt that he was just farting now, and Sakaki Makoto could find a bunch of faults.

He really guessed it.

"When a person is extremely weak or has nothing to do, he will interrupt the other person's words, build self-confidence, and try to regain the right to speak..."

Sakaki begins again:

"It will even become more intense, hysterical, and begin to carry out many different measures such as raising the bar, being unreasonable, threatening, etc...."

"Chief Black Rock, you speak."

"It's not interesting for me to talk about it alone."

Tatsuji Kuroiwa: "....."

What do I say.

What do I have to say.

I really can't stand the birds, I don't speak, my face is expressionless, and I can't do it without movement....

See what other tricks you have ....

"Don't speak."

Sakaki nodded:

"In my experience, many prisoners fall silent when they are cornered."

"Does anyone know why?"

This is a reasoning show, and Makoto wants to use the most high-profile posture to destroy the opponent's psychological defense little by little.

"Yes! Yes! ”

Conan jumped to his feet and raised his little hands.

"Very well, Conan-san, it's up to you to answer this question."

Sakaki pushed down his sunglasses, just like a teacher pointing to a human specimen and teaching actual combat.

was named, Conan shook his head, like a genius who recited poetry, and said slowly:

"As we all know, silence is a form of cold violence."

"The silence and non-response of the prisoners are their last resort, believing that this will make the questioner helpless and thus exonerate him."

"But in fact, their behavior of not speaking or expressing their position just proves that the questioner's previous statement is correct."

"The dumbness of the Black Rock Village Chief when he was asked proves that he is a thief!"

After speaking, Conan raised his head obediently and smiled innocently:

"Brother Sakakikoto, am I right?"

“Bravo！”

Sakaki gave a thumbs up and pulled out the fruit candy from his pocket:

"That's great, I'll reward you with a piece of candy."

"Thank you, sir... Big brother Makoto! ”

Looking at the atmosphere of the strong teacher-student relationship between the two....

Kuroiwa felt as if someone had stuffed a pound in his chest, and he couldn't speak.

He wanted to scold his mother.

But there is no classic national scolding in the language.

So he can't scold ....

"Proof!"

As one of the three stinkers, Hideo Kawashima, who can barely be called Wolong, glared at the unassuming Kuroiwa Chenji at this moment, and issued a final question:

"It's useless to say this, we want evidence!"

"Otherwise, you will not be condemned!"

"Hmm...."

Sakaki pressed his hand to his chin and thought for a moment.

He really didn't have any substantial evidence.

If nothing else, the other party should have disposed of the syringe....

As for fingerprints....

He couldn't be sure if the other party was wearing gloves when committing the crime.

If you wear it and you question it again, it is likely to make the psychological pressure just exerted undone, so that the other party can restore confidence and be more tight-lipped.

When he faced the psychiatrist Nano Uekawa, he failed once.

The other party is a veteran, specializing in psychology, and it is normal to know how to counter psychological suggestion....

But the three of Kuroiwa didn't know.

In that case, it is necessary to find out what they will definitely ignore....

Sakaki's gaze wandered from the top of the three of them to the soles of their feet.

Hehehe....

"Chief Heiyan, the shoes you wore when you committed the crime yesterday...."

A gleam flashed in Sakaki's eyes:

"It should still be at home."

"Have you disposed of the dirt on it?"
