Chapter 621: Miyano's First Teaching (Please Vote and Subscribe!!!)

"Oh~~"

Mu Mu Shisan suddenly realized:

"So, Brother Sakaki, you said before that even the prisoner himself doesn't know when the lock will break. That's why!"

"That's right."

Sakaki nodded:

“Even if cold brittleness occurs, the lock is still a lock.”

"It may or may not break, but"

"Prisoners can make countless mistakes, but Captain Haneda will die if he makes one mistake!"

"If I'm not wrong."

"In order to ensure that you can kill Captain Haneda, you must have stored liquid nitrogen elsewhere!"

Conan and Hattori Heiji, who had always been silent, took a deep breath.

That's right

This is indeed a perfect murder.

If Saijo had been more cautious, he would have had a chance to dispose of the stored liquid nitrogen.

Any evidence or clues will disappear without a trace.

It is impossible to solve the case!

who would have thought

Can you kill someone perfectly using only liquid nitrogen?

As Sakaki Cheng said, the liquid nitrogen killing method requires a specific profession and time to be successful.

Circus Sunshine.

Exactly in this category.

"That's wrong"

Takagi Wataru, who likes to ask questions, started to shine after hesitating for a while:

"There is a loophole!"

"The metal that has been cooled by liquid nitrogen should be different from other locks!"

"It's definitely different."

Pursing his lips, Sakaki said:

"I would like to ask my assistant, Hui Yuan Ai, to answer your questions."

Turning her body sideways, Miss Miyano outside the door was stunned for a moment.

Until Takagi Wataru cast a look of eagerness to learn.

Only then did she react, glared at her boyfriend dissatisfied, and raised her head proudly.

This little bit of knowledge can’t trouble her at all!

"As Cheng said just now, the toughness of most metals is affected by temperature. This is because the crystal structure of the metal changes due to temperature. It is related to the smelting level and material type. It is also called the ductile-brittle transition temperature. "

Miss Miyano threw the scientific theory directly in Takagi Wataru's face, regardless of whether he could understand it or not:

"Most of the metals mentioned here usually refer to body-centered cubic metals, that is, chromium, tungsten, alpha iron, etc."

"But some metals are very low affected by external temperature, usually face-centered cubic metals, such as aluminum, copper, gold, silver, gamma iron, etc."

"Akito sack!"

Takagi Sheba was confused when he heard this:

"Aren't alpha iron and gamma iron both iron?"

"They are indeed iron atoms, but at different temperatures the iron atoms have different crystal structures."

Glancing at him, it was clear that Miss Miyano had never brought up such a stupid student before, and said with some displeasure:

"Pure iron is below 912°C, and the iron atoms are arranged in a body-centered cubic lattice, which is called alpha iron."

"Between 912°C and 1394°C, iron atoms are arranged in a face-centered cubic lattice, called gamma iron."

"When the temperature exceeds 1394°C, the iron atoms will rearrange into a body-centered cubic lattice, called delta iron"

"Officer Takagi, you still need to study more."

"oh"

The old man's face turned red, and Takagi Sheba hesitated and said:

"Aren't I learning?"

“What does this have to do with metal being cooled by liquid nitrogen?”

"fool!"

Miss Miyano held her forehead and sighed:

"Didn't you realize something about the three temperatures I just mentioned?"

Takagi Sheba shook his head blankly.

What goes in the left ear and goes out the right ear, he doesn't know how to draw inferences.

"well"

Miss Miyano suddenly understood why Sakaki looked tired every time he solved a case.

This kind of teammate

What thick thighs are needed to carry it!

"Don't the three examples I cited just prove that the crystal structure of steel will shift and change depending on the temperature?"

She hated that iron could not become steel and said:

"Crystal structure transformation is reversible, reversible, reversible!!!"

"You can't even imagine this, why do you think you're a detective?"

"The prisoner is dying of laughter!"

I don't know why

After being scolded by Miss Miyano,

All the police officers, including Takagi Wataru, lowered their heads in shame.

They didn't expect the feelings at all.

Genius is genius. Others will only take notes after hearing this, but Miss Miyano can instantly think that the crystal structure will change according to the temperature.

Being so smart, it is more than enough to develop APTX4869.

If you try to figure out 'ordinary people' with your genius' thinking, the result will definitely be disappointing.

but

As if he was enlightened, Takagi Sheba was scolded, and his two channels of Ren and Du were completely opened, and he transformed into a little genius:

"I see!"

"Because the crystal structure of steel is reversible, as long as the lock that has been soaked in liquid nitrogen returns to normal temperature, there will be no traces left!"

"It's summer now, and the indoor and outdoor temperatures can reach 36 degrees Celsius. By the time the police arrive at the scene, the last clue will be gone!"

"What a great move!"

Mu Mu Thirteen: "."

"Takagi, are you out of your fucking mind?!"

"Why are you praising the prisoner?!"

"Memu Police Department."

As if he had become a different person, Takagi Wataru actually patted his boss on the shoulder twice and said sincerely:

"It's not important."

"The important thing is that we now know the criminal's methods, and it's time to close the net!"

"????"

Mu Mu Shisan, who looked surprised and uncertain, touched his forehead and said worriedly:

"Takagi."

"You, you won't be called stupid, will you?"

"I'm healthy!"

Takagi Wataru hit his chest and stood at attention on the spot:

"Please order the arrest of Masato Saijo!"

"ah"

Mumu Shisan looked at this subordinate who had taken the wrong medicine, then turned around and asked:

"Masato Saijo, do you plead guilty?"

"What crime do you plead guilty to?"

Deputy Commander Saijo looked ferocious and his neck was red, as if he had just finished a sauna:

"From beginning to end, you cough!"

"You haven't produced any evidence!"

"You just want me to plead guilty with empty words?"

"Go ahead and dream!"

This class of prisoners is obviously difficult to manage.

Under normal circumstances, when the modus operandi of the crime is discovered, the prisoner should kneel down, cry bitterly, and repent loudly.

but.

Masato Saijo was completely at odds with the evidence.

He would never plead guilty without evidence.

Lao Lai.

"Takagi, search the circus for tanks containing liquid nitrogen!"

Mumu Shisan issued the order:

"Wait a minute!"

"You are in a bad state today, so you should not go. Chiba, you will be responsible for this matter!"

"yes!"

The round-cheeked Chiba and Nobu took over the task, took the two of them and set off.

Masato Saijo looked at them with disdain, unmoved.

He's not stupid.

Tank containing liquid nitrogen.

It had long been quietly hidden.

No one can be found.

"that."

At this moment, Qianxia, ​​who was wearing a single ponytail, suddenly bent down and pulled out a cylindrical iron bucket from the debris piled outside the door:

"Look, is it this jar?"

Saijo Masato's face stiffened and he slowly lowered his head.

Looking at the familiar yet dazzling jar.

He was furious and roared:

"Chinatsu!!!"
