The man who had completely lost his vital signs, the chair blackened with blood, the dimly lit surroundings, the various objects scattered on the ground, and the pistol that had taken the life of the man.

The environment at the scene was as miserable as when Su Yuan first entered.

Walking to the low table, Su Yuan lifted the pistol that had been sealed by the file bag with one hand, and it was said that it was only stained with Lu Renjia's fingerprints.

The pistol is the same .38 caliber as Mr. Qin said, but judging from its awkward appearance, it seems to be a homespond. Because Su Yuan has practiced this thing for a while, he has never heard of such a strange person in the pistol world.

(Is this pistol that took the life of the boss's uncle?) ）

(The exhibit [murder weapon] has been added to the search file.) ）

"No, the little ghost of the Su family, let's take a look at this after reading the murder weapon."

Teacher Qin, who was behind Su Yuan, saw that Su Yuan had already seen the pistol, and threw over something like a file bag. After Su Yuan unwrapped the kraft paper, he found a piece of paper lying quietly inside.

"Is this an autopsy report?"

"Wouldn't you just know by looking at it? Inspector? ”

Su Yuan didn't bother to pay attention to Teacher Qin's complaints, and read the autopsy report.

The autopsy report has all the information about the name of the deceased, the estimated time of death, etc., but Su Yuan knows all this, so he doesn't bother to read it. What caught Su Yuan's attention was the small print at the bottom.

"Cause of death...... Pierced through the heart by a bullet at an extremely close range of less than one meter...... Instant death......"

(The exhibit [autopsy report] has been added to the search file.) ）

(The exhibit [top view of the crime scene] has been added to the search file, specifically a square space surrounded by partitions on three sides, and the remaining side is mostly covered by shelves, and behind the shelves is a long table with a short side facing the shelves, marked "be" on the inside of the table, and "murder" on the outside.) ）

"Hey, boy Su, have you finished reading?"

"I'm done, but it's ......"

"Hurry up and sign it for me when you're done! There is a murder here, and there are as many miscellaneous things as a mountain about dealing with the prisoner, pacifying the masses, and going back to discuss how to deal with this student, now that the situation is clear, hurry up and sign it! We don't have as much time as you do! ”

"However, since the scene has not been fully investigated! How can you make a conclusion about who the real murderer is! Su Yuan immediately retorted.

"Oh hehe...... Teacher Qin chuckled again, "Okay, I know what you guys think, isn't it just that you don't usually see such a scene, and you want to play a reasoning game and show off your majesty?" ”

“…… If you really think so. ”

"Okay, then I'll let you see my Qin Zhen's ......"

"Perfect reasoning!"

"I want to hear about it."

(Mr. Qin, you may not understand, but there are as many doubts on the scene as there are mountains like your work!! ）

(If there is a doubt, there must be a flaw in the reasoning that ignores the doubt.) ）

(Since there is a flaw, then it is up to me Su Yuan to make what you call "perfect reasoning"...... ）

(Break them one by one!! ）

―――――― Teacher Qin's Perfect Reasoning~1――――――

(1) "Listen, that guy named Lu Renjia came here because of business matters. ”

(2) "During the conversation, the two disagreed and had an argument! ”

(3) "The angry Lu Renjia took out his pistol and shot the victim in the heart!" ”

(4) "This is the whole picture of this case, and the whole reasoning process is impeccable!" ”

――――――――――――――――――――――

(huh...... Is it impeccable? If there are doubts, how can they be invulnerable? ）

(Let me take the flaws in your reasoning...... Expose it! ）

"That Lu Renjia...... He's just your student in Class B, right? What business is there to talk about? ”

"What I call talking about business...... But even buying a cookie is included? Besides, that Lu Renjia is no longer my student, from the moment he did such a thing. ”

(I still insist that Lu Renjia did it...... ）

"You said they had an argument...... So what exactly is the content of the dispute? ”

"This has nothing to do with this case, it's all about what he 'did', isn't it?"

(It was pushed back again, it seems that Mr. Qin will not be convinced without some conclusive evidence...... ）

"Lu Renjia is just an ordinary student, where did he get the pistol? Where did you get the marksmanship of hitting the heart directly with one shot? ”

"That kind of ** looks homemade, right? Besides, it's important that Lu Renjia hit the victim in the heart, not how he hit it, isn't it? ”

(Still sticking to your own point of view...... The important thing is that he hit the victim in the heart? And not how to hit? …… ）

（…… Right! The so-called "flaws" are here! ）

"Haha, haha, hahaha!!" Su Yuan laughed unconsciously.

"What are you laughing at?" Teacher Qin frowned, "If you understand, hurry up and sign it!! ”

"I see, I really do...... Got the hole in your reasoning! ”

"You deduce that Lu Renjia shot the victim in the heart and died, but this is simply impossible."

"Look at the floor plan, Lu Renjia is on one side of the long table, and the victim is on the other side, there is a considerable distance in between. And look at the autopsy report ......"

"The bullet holes showed strong burn marks, and the victim was killed by a bullet fired from extremely close range......"

"That's the flaw in your reasoning!!"

Teacher Qin frowned and fell into deep thought. Soon, though, her brow furrowed again.

"Su boy, you have a set...... However, your so-called 'flaws' only need to be corrected in a small place. ”

(Since there are still doubts on the scene, there are still flaws in the reasoning based on them...... ）

"I'm still the same sentence," Su Yuan smiled, "I'd like to hear it." ”

―――――― Teacher Qin's Perfect Reasoning~2――――――

(1) "The cause of the incident is the same as before, Lu Renjia came here to discuss business with the victim. ”

(2) "During the conversation, the two disagreed and had an argument! ”

(3) "During the dispute, Lu Renjia took out his pistol in a fit of rage! ”

(4) "Seeing this, the victim hurriedly dodged and had a fierce scuffle with Lu Renjia in order to take away the pistol! ”

(5) "In the process of scuffling, Lu Renjia found an opportunity to put the pistol on the victim's chest and pull the trigger!" ”

――――――――――――――――――――――

"How? It not only explains the reason why the victim was shot at extremely close range, but also finds a reason for Lu Renjia to hit the victim in the heart with one shot. Teacher Qin looked very enjoyable, "Su boy, I admit that you found the shortcomings of my previous reasoning and guided me to make additions to it." But can you still find a flaw in my 'perfect reasoning'? ”

Su Yuan didn't answer, but he was secretly observing the dead boss uncle with the rest of his eyes, comparing it with the arrested student in Class B.

(Looking at that classmate's thin size, if it were to scuffle, would it really be an opponent for the bear-sturdy boss uncle?) ）

(So, there's definitely a problem in it!) ）

After being silent for a long time, Su Yuan spoke:

"Lu Renjia's body is thin and weak, if he fights, he will generally not be the opponent of the boss uncle, shouldn't he choose to shoot continuously in this case?"

"Hehe......" Teacher Qin had an expression of "I expected you to say this", "Su Xiaozi also noticed that this is unnatural, but I said it a long time ago, right?" It is important to note the result rather than the process, and in the scuffle, Lu Renjia found an opportunity to shoot the victim in the heart, isn't it obvious? As for why he didn't choose to shoot continuously, it may have other concerns......"

(No, no!) The process must not be overlooked! Since the reasoning is unnatural, there must be evidence of contradiction! ）

After being silent again for a long time, the corners of Su Yuan's mouth gradually hooked up, forming a wonderful arc.

"Teacher Qin, you are a teacher, you should understand the truth that when you do a question, the more perfect the answer you get, the more likely you are to fall into the trap of the questioner...... Looks like I've found a flaw in your reasoning again......"

“……！”

"In your reasoning, you think that Lu Renjia had a scuffle with the victim, but why is there only Lu Renjia's fingerprints on the pistol?"

“……”

Teacher Qin's face became heavier and heavier.

"Since there was a scuffle, there must have been fingerprints of both men on the pistol. If it is to exonerate yourself, you either simply erase all your fingerprints, or keep all your fingerprints. If all the fingerprints are kept, they can still claim 'legitimate defense' and snatch the pistol from the victim, but now there are only Lu Renjia's fingerprints on the pistol, and Lu Renjia does not have the ability to erase the fingerprints of one of the parties alone......"

"So, the final conclusion is, the so-called scuffle ......"

“……”

"It didn't happen at all!"

Teacher Qin, who was still triumphant just now, fell into deep thought at this moment, while Su Yuan waited quietly on the side.

Before I knew it, an hour had passed since the moment the case occurred.

“…… The above has already been notified, this murder case is related to Niu Easter's reputation, and it must be completed as an iron case that can stand the verification of history. Teacher Qin raised his head and said solemnly, "I considered several possibilities just now, and there are all such and such problems, so I ...... say."

"Su Yuan, you are right, this case needs further investigation."

"Teacher Qin can call me by my real name, and I am very grateful." Su Yuan responded with a smile.

(Looks like my instincts were right!) There is something wrong with this case! ）

(In that case, let me put those questions into account...... ）

(Reveal it!! ）
