Judging from the thick smell of blood, the location of the corpse had obviously shifted from the scene of the first crime to another location, so the man with the glasses had no fear, and when he led the way, the corners of his mouth swept over the corners of his mouth.

Ogata smiled, the man seemed to be smug about his modus operandi, but soon he would show up, and when the forensic doctor appeared at the scene of the crime, his methods of confusing the crowd would be like a funny farce.

At the end of the hallway, when Twilight and several police officers push open the bathroom door, and a picture of a dead body lying in a pool of blood has formed in their heads, they are surprised to realize that the truth is not as expected.

The spacious bathroom is very clean and tidy, with a bloodless bathtub, milky white tiles, neatly arranged toiletries, and things that are often used in daily life, but there is no corpse covered in blood as Conan said

"How so!" The four imps of the Junior Detective Team were a little dumbfounded when they saw the bathroom where there was nothing, because they were sure that there was a dead body just now.

"How could it have disappeared?"

The most surprising of them all was Conan, who would never believe that his eyes were wrong, and that a dead body would disappear under his nose, that someone must have hidden it.

"Hmph." The man with the glasses smiled and snorted softly, "Look! What a corpse, it's these imps playing a prank. ”

The four members of the junior detective team were very unconvinced, and Yuan Tai shouted unwillingly: "But we really saw a corpse covered in blood in the bathroom, you must have hidden it!" ”

"If you talk nonsense here again and delay my time, I will complain to you!" The man didn't pay attention to the policemen and a few imps who were there, and this kind of bad attitude couldn't even be seen by Twilight.

Conan said calmly at this time: "Officer Dusk, fifteen minutes have passed since we called the police, and it only takes about ten minutes to hide a corpse and clean up the traces here. ”

"Conan's point makes a lot of sense." Twilight nodded slightly, and his gaze turned to the owner of the house, the man with the glasses, "If it's convenient, we need to search your home carefully." ”

"Damn! If you're looking for it, let you find one. I'm going to go up to the second floor to sleep, and don't mess with my things, or I'll not only make you pay compensation, but I'll also have to complain about your dereliction of duty. The man said a cold word, then ignored the ugly Twilight and turned to go upstairs.

Twilight clenched her fists and instructed several of her subordinates in a terrible tone, "Give me a careful search of this house, don't let go of every corner, and make sure to find the body." ”

As several police officers set out to search, Ogata returned to the bathroom he had just visited, his nose sniffing hard, his eyes glistening with the aura that remained on the floor and the bath.

"Conan-kun, Brother Ogata, he" Ayumi patted Conan who was lost in thought with her hand, and the latter came back to his senses and looked in the direction of the bathroom.

I saw that Ogata put the toolbox he had been carrying on the ground, and this toolbox contained the tools commonly used in the coroner's department, although many of them were already behind the forensic profession in the United States, but at this time, it could still come in handy.

Taking out a pair of white gloves from the toolbox, Ogata slowly put them on top of his hands, and with a nimble movement of his fingers, he found a bottle of yellow powdered agent at the bottom of the toolbox, which was the 'light ammonia' that forensic doctors often use.

The so-called light ammonia, also known as luminol. In the explanation of common terms, luminol is a strong acid, which has a certain irritating effect on the eyes, skin, and respiratory tract.

In the forensic textbooks that Ogata had learned, luminol was an essential reactive substance. Its role at the scene of the crime cannot be ignored, and even in the 21st century, the same method is being used to identify the scrubbed blood stains of a long time ago.

Ogata gently sprinkled the yellow powdered ammonia from the bottle on the side of the tub and on the ground where he smelled the foul smell, slowly waiting for the change, while the curious young detective team approached.

"What is this?" Mitsuhiko asked Ogata with great interest.

Ogata glanced at him and explained slowly, "Luminol reaction. Human blood contains hemoglobin, which is used to transport the oxygen we breathe from the air to all parts of the body. Hemoglobin contains iron, and iron catalyzes the breakdown of hydrogen peroxide, turning hydrogen peroxide into water and monooxygen, which re-oxidizes luminol to make it light. ”

"Huh?" Harata and Ayumi were dumbfounded, feeling that what Ogata said was like listening to a book from heaven.

While Conan and Mitsuhiko listened with relish and seemed to benefit a lot, Ogata continued with a smile, "In the process of examining blood stains, luminol reacts with heme and shows blue-green fluorescence. This test is extremely sensitive, capable of detecting as little as one part per million of blood, even if a small drop of blood is dropped into a large tank of water. ”

"That's amazing!" Mitsuhiko looked in amazement at the place where the ground was gradually reacting.

Conan and a few other imps looked at the surface of the tub and the floor after Lumino's reaction, and now showed the blue-green fluorescence that Ogata had mentioned, and everyone shouted with joy.

"That way, we can prove that we're not lying!" Harata excitedly looked at the luminol reaction that shone with a faint fluorescence, and said to Mitsuhiko Conan and Ayumi.

Ogata smiled slightly, and he shook his head, "Even if there is a blood reaction, there is no way to prove that there is a corpse covered in blood that you say has appeared here. ”

"Why?" Yuan Tai asked hurriedly.

Conan replied, "Just checking out the blood reaction here doesn't mean anything, because the man could have made up a reason that he fell in the bathroom or accidentally injured himself." ”

"You're smart, Conan." Ogata praised it without hesitation.

Conan was not embarrassed, he completely accepted, pushed his glasses and asked, "Brother Ogata, is there any way you can find that corpse?" ”

"Yes! Brother Ogata, help me find that corpse, or the wisdom of our young detective team! Mitsuhiko said eagerly.

Ogata didn't have much experience in coaxing children, so he said helplessly, "You guys stay quiet, and it shouldn't be a problem to find the body." ”
