"The Great Detective Maori?"

Hearing this name, Sakaki Makoto was stunned at first, then asked:

"Moori Kogoro?"

"Yeah, speaking of the Great Detective Maori, who else could it be but him!"

Shancuncao took it for granted:

"Sleeping Maori Kogoro, I'm his die-hard fan! If you are also a detective, you must know him!"

“.......”

The sleeping Kogoro is certainly not in Gunma Prefecture, but his 'real body' Conan is lying in the hospital right now.

"know."

Sakaki Makoto nodded:

"And very familiar."

"So he's Mr. Maori's friend!"

Shancuncao's eyes suddenly lit up:

"Then you are definitely not criminals!"

"Police Department..."

Behind him, his men all looked as if they had lost all hope in life.

With such a boss, can you solve the case...

It all depends on God's will.

After learning that Sakaki Makoto and Maori Kogoro knew each other, Yamamura So's attitude changed 180 degrees. He walked into the house and asked:

"Have you identified the criminal?"

"Unfortunately, not yet."

Sakaki Makoto was telling the truth. The information he had collected so far was not enough to deduce the identity of the criminal.

There was no way. There were too many suspects, the only piece of evidence was a coal stove, and the clue was single, so there was no way to start the investigation at the moment.

"Come to think of it, when we were secretly eating steak in the kitchen earlier, Ms. Sera mentioned something very strange."

At this moment, Kidd suddenly spoke:

“She said the premium wagyu turned red.”

"What?"

Sakaki Cheng paused, turned back suddenly, and stared at him intently:

"The beef turned red?"

"Yes, it's very strange. The steak in the refrigerator should be red with a hint of black after thawing, but after being placed on the table for a while, it gradually becomes much brighter, just like the fresh meat under the ultraviolet light in the supermarket."

"Carbon monoxide!"

"Oh shit, yeah!"

After Sakaki Makoto's reminder, Kid realized why the beef turned red.

"Nani? Nani?"

Yamamura Cao looked around and found that he could not fit in the conversation between the two people at all:

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

"Beef is rich in hemoglobin, and carbon monoxide has a much stronger affinity with hemoglobin than oxygen. In this case, the beef placed in carbon monoxide will be brighter in color than the beef placed in oxygen!"

A trace of cold sweat oozed from his forehead, and Sakaki Makoto said to himself:

"The fundamental reason is that the maximum absorption peaks of hemoglobin combined with carbon monoxide are 570 nanometers and 542 nanometers, which is a brighter red than oxygenated hemoglobin, and carbon monoxide hemoglobin has the characteristic of being dissociated by light!"

"ha....."

Shancuncao still didn't understand.

"Generally speaking, if the color of beef becomes unusually bright, it is usually because of a gas leak or excessive concentration of carbon monoxide in the air!"

Sakaki looked at Kidd and said in a resounding voice:

"Did you burn the coal when you stole the food?"

"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!"

“But…but…”

As he spoke, Kidd became confused again:

"The kitchen is also a semi-enclosed space. If the coal stove emits a lot of carbon monoxide when burning, why didn't we get poisoned?"

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

The high-power range hoods used in the kitchen are not very effective. If the suction power is not strong, how can the fumes be drawn out?

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

Recalling the scene of himself standing in the kitchen and eating with grease dripping from his mouth, Kidd broke out in a cold sweat and was filled with fear.

He and Conan had a close call with the devil, and even had one foot in it. Fortunately, they were lucky and nothing tragic happened.

"So... someone has already sprinkled silicon dioxide into the coal?"

Kidd frowned:

"This plan was not something the criminal came up with on the spur of the moment, but was premeditated?"

“The possibility is very high.”

Sakaki Makoto said in a low voice:

"The criminal had already prepared to assassinate Ogawa Yoshio in this way. Our arrival only accelerated his progress."

"So the chef is the criminal, right?"

Shancuncao reacted at this moment:

"They purchased all the coal, so they are definitely the most suspicious!"

After stating the conclusion, Shancuncao felt somewhat complacent, thinking that he had been of great use, but he did not expect that...

Sakaki Makoto glanced at him and immediately denied it:

"It's not the chef. It's because chefs are most likely to come into contact with coal. There's no need for them to add silica to the coal in advance to put themselves in danger. They can just sprinkle it in when committing the crime. Why bother? The murderer is someone else."

"The key to the case is who entered the kitchen and touched the charcoal stove before and after the incident. It's a pity that the Ogawa family didn't install surveillance cameras, otherwise there would be no need for such trouble..."

Miss Miyano and several others were admitted to the hospital, and the police were useless. The only one who could give advice to Makoto Sakaki was Kidd, and the criminals had a thorough plan, so the situation was very unfavorable for them.
