"The Great Mori Detective?"

Upon hearing this name, Sakaki was stunned for a moment, then asked:

"Moori Kogoro?"

"Yes, when it comes to the great Maori detective, who else can there be besides him!"

Yamamura Cao looked matter-of-factly:

"The sleeping Kogoro Mouri, I am his biggest fan! If you are also detectives, you must know him!"

"."

Of course the sleeping Kogoro is not in Gunma County, but his 'body' Conan is lying in the hospital at the moment.

"know."

Sakaki nodded:

"And very familiar."

"It turns out to be Mr. Mori's friend!"

Yamamura Cao's eyes suddenly lit up:

"Then you must not be criminals!"

"Police Department."

Behind him, his subordinates all looked helpless.

With a boss like this, he can solve the case.

It all depends on God’s will.

After learning that Sakaki Makoto had met Mouri Kogoro, Yamamura Soo's attitude changed 180°, and he asked as he walked towards the house:

"Have you locked down the prisoner's identity?"

"Unfortunately, not yet."

What Sakaki said was true. The information he had collected so far was not enough to deduce the identity of the prisoner.

There was no way, there were too many suspects, the only evidence was a coal stove, and there was only a single clue, so it was impossible to investigate for a while.

"Speaking of which, when we were eating steak in the kitchen, Miss Sera mentioned something very strange."

At this moment, Kidd suddenly spoke:

"She said the premium Wagyu beef has turned red."

"What?"

After a pause in his footsteps, Sakaki turned around suddenly and stared at him:

"Is the beef turning red?"

"Yes, it's very strange. After thawing, the steak in the refrigerator should be red and black in color. But after it was left on the table for a while, it gradually became much brighter, just like when placed under a purple light in a supermarket. Like fresh meat.”

"Carbon monoxide!"

"Oh shit, yes!"

After Sakaki's reminder, Kidd realized the reason why the beef turned red.

"Nani? Nani?"

Yamamura Soo looked around and found that he was completely unable to integrate into the conversation between the two:

“What does the redness of beef have to do with carbon monoxide?”

"Beef is rich in hemoglobin, and the affinity of carbon monoxide to hemoglobin is far greater than that of oxygen. In this case, the color of beef placed in carbon monoxide is more vivid than that of beef placed in oxygen!"

A trace of cold sweat broke out on his forehead, and Sakaki said to himself:

"The fundamental reason is that the maximum absorption peaks of combined carbon monoxide hemoglobin are 570 nanometers and 542 nanometers, which is more vivid red than oxyhemoglobin, and carbon monoxide hemoglobin has the characteristics of being photodissociated!"

"ha"

Yamamura Cao still didn't understand.

"In layman's terms, if the color of beef becomes extremely bright, it is usually because of a gas leak or the concentration of carbon monoxide in the air is too high!"

Sakaki looked at Kidd and said loudly:

"Did you burn coal when you ate it secretly?"

"right!"

Kidd nodded and said:

"Chef Long Da said that if you want to make a good steak, you must use a charcoal stove, so that the fire is gentle and will not destroy the taste of the ingredients!"

"Cocoa"

As he spoke, Kidd was a little confused:

"The kitchen is also a semi-enclosed space. If the coal stove emits a large amount of carbon monoxide when burning, why are we not poisoned?"

"It's simple, because the high-power range hood used in the kitchen is filtering the air, otherwise you would have been poisoned."

The high-power range hood used in the kitchen is very effective. If the suction power is not strong, how can you extract the fumes?

Overall, Kidd and others were saved by the range hood.

Recalling the scene where he stood in the kitchen and devoured the food, his mouth full of oil, Kidd broke into a cold sweat and was terrified.

He and Conan and others walked through the Gate of Hell once, even half of their feet had stepped in. Fortunately, they were lucky and no tragedy occurred.

"Then it means that silica has been spilled into the coal for a long time?"

Kidd frowned:

"This plan was not improvised by the prisoner, but was planned in advance?"

"The likelihood is very high."

Sakaki said in a low voice:

"The prisoner has been preparing to assassinate Yoshio Ogawa in this way for a long time. Our arrival is just to speed up his progress."

"So the chef is the prisoner, right?"

Yamamura Cao reacted now:

"They bought the coal, so they must be the most suspect!"

After saying the conclusion, Yamamura Cao felt a little complacent, feeling that he had been of great use, but he did not expect

Sakaki glanced at him and immediately denied:

"It's not the chefs. Just because chefs are most likely to come into contact with coal, they don't need to add silica to the coal in advance to create danger for themselves. They can just sprinkle it in temporarily when committing the crime. Why bother? There is another murderer."

"The key to the case is who entered the kitchen and came into contact with the carbon stove before and after the incident. It's a pity that the Ogawa family did not install a monitor, otherwise there would be no need for such trouble."

Miss Miyano and others entered the hospital, and the police were of no use. Kidd was the only one who could advise Sakaki Cheng. The prisoner had a well-planned plan, and the situation was quite unfavorable to them.

"I remembered!"

Kidd shouted:

"Akutagawa Fuuna has entered the kitchen!"

"At that time, she came to ask about the dinner time and urged Longda and the others to hurry up. Later, when dinner was served, she could naturally touch the coal stove!"

Having said that, Sakaki Makoto always felt that something was wrong.

His intuition told him that this case was different from the previous ones and could not be speculated according to normal thinking. The criminal seemed to be playing hide-and-seek with them, laying down a lot of fog just to confuse their judgment.

At present, there are six criminals who are known to have access to the coal stove, namely the three chefs and Akutagawa Fuuna and her daughter and granddaughter.

When the three chefs were ruled out as suspects, it seemed that Akutagawa Fuuna was the only suspect left.

"No, no"

Sakaki Makoto frowned and thought, turned around a few times, and muttered:

"Silicon dioxide. Where did the criminal get the silicon dioxide? Who proposed to install the central air conditioner? The beef turned red."

The clues were too scattered, and if they wanted to connect them, something key was missing.

Dinglingling!

Ding-ling-ling!

Just then, the phone in his arms suddenly rang. Makoto Sakaki took it out and looked at it. His tense mind immediately relaxed a lot.

Caller ID: Ai Huihara

"Are you okay?"

After answering the phone, Makoto Sakaki couldn't wait to ask:

"How is your health?"

"I still feel a little dizzy, but it's nothing serious."

A familiar voice came from the microphone, it was Miss Miyano:

"Are you investigating the case?"

"Yes."

"Come to the hospital quickly, Ogawa Yoshio is not in good condition."
