() Gojo Xiu and Ichi Takashi did not expect that the forensic doctor promised to give an answer in an hour, but he really fulfilled it.

Glancing at the body of Nikaido, they really couldn't see that there was any evidence that could identify the murderer. The more suspicious they were in their hearts, the more curious Xun Fang's next deduction was.

"Mr. Ogata's name, I have read it in the newspaper. As Japan's leading forensic doctor, I really want to see the difference between the forensic doctor and the detective's approach to solving cases." Liutian General Si stood at Pang's place skillfully, and said Said.

Ogata nodded and became the focus of everyone's attention: "Before the autopsy report, I want to tell everyone. The two most painful ways to die in this world are drowning and burning. Even if your flesh is sliced Even if the pieces are cut off, it will not be able to achieve the pain of these two ways of death."

Everyone looked at the dead Nikaido Yuji, his face was ferocious and distorted, it seemed that just as Ogata said, he was suffering from pain and suffering at the moment of death.

"The drowned person refers to the suffocation death caused by the obstruction of the respiratory tract by liquid, which is also called drowning." Ogata walked up to the corpse and pointed to the naked upper body: "Drowning can be divided into general and suffocation. The skin of corpses salvaged in seawater swells and falls off, and the liquid seeps into the skin, causing the epidermis to swell, whiten, and wrinkle. But we all know that there are no rivers and oceans nearby, so the most likely place for the crime is the one near the corpse. fountain."

"The surface of the corpse is extremely smooth, but the blood vessels and tendons are protruding, maintaining a certain degree of elasticity. It is because the blood is mixed with a large amount of water from the respiratory tract, which makes the blood vessels expand and maintain an upper limit of contraction. The reason why it is called drowning The dead person will be very painful, because you will feel that first, the mouth and nose are filled with liquid. Then the liquid fills your lungs, heart, blood, and the whole person is like a balloon, slowly swelling and suffering Waiting for the internal organs to be unable to support the encroachment of these large amounts of liquid, there is a feeling of bursting at any time."

Ogata walked up to the head of the corpse, squatted down, and everyone's eyes followed him involuntarily.

"The evidence of a general drowning corpse all points to the fact that the deceased was struggling violently. There are foamy drowning liquid, aquatic plants, sediment, plankton and other foreign objects in the respiratory tract, the sphenoid sinus cavity communicating with the mouth and nose, and the lungs. In Kaidou's nose and mouth, we can see that there are a lot of white air bubbles."

Ogata looked at everyone and asked: "Do you know what the measures taken by the fountain to prevent the gushing water from causing the water in the pool to flow too much to form foam?"

Everyone shook their heads. Most of these people were rich young masters who stretched out their clothes and opened their mouths.Of course, the construction system of a fountain will not be known.

Including Mori Kogoro, he is not very clear about the knowledge of fountains.

Ogata saw Conan thoughtful, obviously this brat should know, it's just not convenient to speak.

"It's a nitrification system. With nitrifying bacteria as the core, the biological water purification system used to eliminate nitrate in water has a very important effect in the purification of nitrogen cycle water quality. Compared with normal water sources, the water after nitrification will have some Viscous, even salty."

Hearing Ogata talk about the cleaning system of the fountain, Gojo Osamu finally couldn't help asking: "Is there any direct connection between these things and Nikaido's death?"

Takashi Ichieda nodded in the same way, although Masaki Muta said that he also suspected that Ogata was deliberately going around in circles, what he said.There is no substantive advancement of the case.

"Listen to what I'm going on, you'll have some enlightenment." Ogata was not influenced by them.An unhurried tone.

Mori Kogoro sweated for Ogata, because it is definitely not easy to find out who the murderer is in an autopsy of a drowned corpse.In his opinion, Ogata's action of promising to give detailed results in "one hour" today is young and vigorous.

"Back to what I mentioned before, there is a lot of foam remaining in the breath of the deceased. This is a very normal performance of a drowned person. Because when the murderer held down Nikaido and poured water forcefully, the deceased would also Breathe, and these fluids reach the body and form a feedback, causing the fluid to flow back, forming foam with each breath."

Ogata pointed to the mouth and nose of the corpse, and looked closer: "But you can observe that these bubbles are very persistent and the drainage speed is slow. The formation of each bubble, in addition to the strength and elasticity, there are also factors that affect the stability of the foam. There are bulk phase viscosity and surface viscosity. The bulk phase viscosity and surface viscosity are large, and the foam is stable."

"Enough, is this the inference of your forensic doctor?" Takashi Ichiji pushed his glasses and said mockingly.

Xiaolan looked at Ogata anxiously, because his deduction today was really different from usual, and he talked about a lot of things that had nothing to do with the corpse.

Ogata ignored Ichitaka, and continued: "Whether it's the foam or the cleaning system of the fountain, the only thing I want to tell you is the reason why the remaining time of the foam in the breath of the deceased will remain so under our observation. It took a long time, because the pool water contains a lot of nitrates!"

"Nitrate?" Hearing this, Ichieda Takashi, Gojo Osamu, and Mukuta Commander, these outsiders who were still doubting Ogata's level, were all taken aback.

"That's right, the so-called nitrification system is the process of converting ammonia into nitrite and then into nitrate in the state of circulating filtration. When we found the corpse, I found nitrification on the wall of the fountain. The filter nozzle of the system. So I can tell you with certainty that the body of the deceased Nikaido Yuji contained nitrates unique to the treated pool water.”

Ogata paused, and then explained: "Nitrate is a relatively unfamiliar term. It is a salt composed of metal ions or ammonium ions and nitrate ions. Therefore, before we set a series of inferences, we must have a It is clear that the water source of this fountain is different from the normal water source, and a large proportion of nitrates can be obtained through testing."

Gradually, everyone found that what Ogata said was full of attractiveness, and it was no longer the resistance in their hearts.

"Even if you know that the water contains the nitrates you mentioned, what does it mean?" Masahiro Muta murmured.His demeanor during questioning has clearly changed, because convincing is what matters.

Ogata said: "The drowning person will subconsciously resist at the moment of entering the water, the body will violently break free, and use all the strength of the whole body to make large movements. Therefore, we can see that the corpse of this corpse is stiffer than a normal corpse. The formation speed is faster. And in the process of drowning the deceased, even if the murderer took good care of the deceased, the dead struggle and resistance of the deceased would cause the body to splash into the pool water in the fountain."

In an instant, everyone's eyes changed and their expressions were different.

Mori Kogoro looked at Ogata in surprise. Could it be that he underestimated Ogata's matter? Forensic doctors really have the ability to judge beyond detectives?

This kid!It's not youthful vigor, nor arrogance, but self-confidence under full control.

"I think everyone is very smart. The pool water splashed on the murderer's body, even if it is stained with rain, cannot be completely washed away, and the nitrate content will be detected. However, before I borrow everyone's coat to check, there is still Another thing, the evidence that fully exposes the truth!"

More and more curious, everyone felt that they felt as if they were there, feeling the deduction process described in those newspapers.

Ogata looked at Mori Kogoro: "Before I shared this autopsy report with everyone, I mentioned to my uncle about locking the murderer's height, remember?"

"Yeah." Maori Kogoro nodded.

"In addition to the fact that the murderer was confirmed to be 1.8 centimeters taller than the deceased, I also mentioned that there was a corpse plaque on the neck of the deceased that was obviously caused by pressing hard with the palm."

"It's here." Ogata turned over the corpse of Nikaido Yuji with his hands wearing white gloves, making him face everyone, and he caught a nearly bruised mark on the corpse.

ps: Thinking should not fall into a pattern, you must innovate, you must change your thinking, and you must create a second creation on a certain basis.There is also the most difficult academic question you see, a sentence, a logical structure, which was presented after a lot of effort by Xuehua.
