    Ogata saw that Arata answered quickly, but his face was a little nervous.  It was obvious that he had just put on the police uniform for a few days and had only experienced a few crime scenes and corpses.  Shiratiao arranged for him to do the autopsy with him. To some extent, in addition to letting him learn something, he also increased his practical ability during the autopsy process under his own supervision.  The first thing that forensic medicine must overcome is all kinds of psychological contradictions.  Now Ogata wouldn't feel anything even if he lay on the same bed with the corpse for the night.  After two lifetimes of forensic work, all kinds of psychological fears and discomforts have long since been eliminated.  In his eyes, the corpse, like the wardrobe and desk here, is a subjective factor that records the facts of the crime.  ???Looking at the entire study, which is the scene of the crime.  From the fallen bookshelf, it was obvious that there were scattered objects on the bookshelf, as well as the blood-stained trophy next to the deceased's head.  In the associative space in your mind, some pictures will appear involuntarily.  According to the logic of normal thinking, Ogata inferred that the deceased should have gone to get something from the bookshelf, but he was obviously not tall enough, so he stepped on the railing of the bookshelf.  But he didn't expect that he lost his balance, causing the entire bookshelf to fall down. Among the scattered objects in the process, the hardest trophy collided with the deceased's head, causing him to die.  The whole process definitely makes sense, but it definitely can’t be the truth.  "This should be an accident, right?" Ogata suddenly raised his head and asked the newly arrived coroner Nitta.  Time flies so fast. When he first returned to China, he was a forensic medicine graduate who was not even a coroner. The person who performed the autopsy at that time was Yi Chuan, who is now a colleague or even a subordinate.  Unexpectedly, more than half a year later, his identity has changed greatly, and his reputation has exceeded his expectations.  "Yeah." Nitta nodded quickly, because based on the crime scene and the body with no obvious signs of death, it was indeed an accident.  Moreover, the process of the crime that he constructed in his mind was exactly the same as what Ogata had imagined.  After seeing him nod, Ogata said slowly: "I have nothing to teach you, because you also graduated from this major and were admitted to the Metropolitan Police Department, so you should have solid theoretical knowledge. But here is where the crime happened  At the scene, you must first remember that the first thing you see is an accidental case, and you need to use reverse thinking to deduce it, because it is very likely that what you see with your eyes is fake, and the truth is hidden in the scenes and traps set by the murderer. "  Nitta was startled and looked at Ogata in surprise. His face changed immediately and he asked in disbelief: "Ogata-senpai, could it be a homicide?" Shiratori was making relevant notes with Mrs. Hirota at this time.  Hearing Nitta's voice, he couldn't help but move his eyes towards the corpse.  Because this is also his first time working on a case with Ogata.  Even though he knew that this was a powerful forensic doctor, he knew more about the autopsy report submitted by Mu Mu.  Now that he could see Ogata using forensic science to solve cases with his own eyes, he was still a little excited.  Being watched by Bai Niao and Nitta.  "Even if it's not the case, we should follow this line of thinking." Ogata came to the body and said to him: "You are a surgeon. You should use the information as a reference at the first time, not from these scattered things.  And the collapsed bookshelf. But this corpse!" "From the outside, this corpse is nothing. It should have died from a head impact." Nitta looked at Hirota Masaki's body carefully.  He answered honestly.  Ogata shook his head: "To judge a corpse, you need to pay attention to many details." He slowly squatted down and gently opened the eyelids of the deceased Masaki Hirota with his hands wearing white gloves.  "The human eye is approximately spherical. The eyeball includes the eyeball wall, contents, nerves, blood vessels and other tissues. The eyeball wall is mainly divided into three layers: outer, middle and inner layers. When you open the eyelids of the deceased and take a closer look, you will find the cornea  , there is a large area of ??scleral hemorrhage. As you are a medical professional, you should know very well that one-sixth of the transparent part is the cornea, and the five-sixth of the white part is the scleral hemorrhage, which can indeed be understood as the head.  Caused by impact. But with the height of the bookshelf from the ground, the impact of the trophy and the head of the deceased will definitely not affect the cornea. "Because when the brain is impacted, the intracranial pressure is high and the blood vessels are compressed, which affects the nerves in the brain.  Scleral bleeding is a normal phenomenon. But this normal phenomenon has a specified range! "The range refers to what kind of force can cause the cornea of ??the deceased to bleed. To understand it simply, the corpse phenomenon will appear depending on the degree of impact.  A completely different result will occur. " "You should have heard of conservation of momentum, right?" Ogata looked at him.    Nitta nodded.  "We need to refer to constant force, mass, as well as action time and distance." At this point, Ogata said to Shiratori who was approaching: "Shiratori Police Department, give me a piece of white paper." Hearing this, Shiratori started from himself  He tore out a page from his work notes and handed it to Ogata.  He was very curious about Ogata’s next answer.  "The weight of the trophy is set to be around 500g, and it falls from the height of the bookshelf, which is 210 centimeters. Then we need to enumerate an equation to calculate how much force this trophy exerts on the head of the deceased!" Ogata said  , took out the pen he carried with him, used formulas on the white paper to apply several numerical units, and explained it to Nitta and Shiratori who were standing aside.  When the dense numbers of radicals and numerical units appeared on the white paper, Bai Bird, who was still able to keep up with his thinking, couldn't help but feel his head grow bigger.  This is not forensic science, but a nerve-wracking mathematical calculation.  Ogata circled a set of numbers with the pen in his hand and analyzed calmly: "The final result is that the force of the trophy falling from a height of two meters is not enough to cause the intracranial pressure generated in the head of the deceased to break through the cornea. And the real impact on the deceased is  The force exerted on the head to cause corneal hemorrhage must not have been an extremely coincidental accidental death after the bookshelf collapsed, but someone deliberately hit the deceased's head with a heavy trophy in this study, causing the sclera to bleed.  and severe corneal hemorrhage." Nitta listened with surprise.  And Shiratori finally understood the source of Mu Mu’s confidence that ‘with him at the scene, any case can be solved’!  "Mrs. Hirota, the deceased should have drank alcohol before death. Am I right?" Ogata raised his head and looked at her standing beside him.  Mrs. Guangtian nodded slightly: "My husband did have a few drinks in the morning." (To be continued.
