"Huh? Got it?"

Yan Xi was a little confused, although he was very sure who the murderer was, but he was just speculating on the author's intentions, in fact, he didn't understand the method or anything at all.

"Extrapolating the result from the condition and deducing the condition from the outcome are completely different concepts."

"That's not an answer."

"Well, don't worry."

Mo Ming smiled slightly, now he just felt that the puzzle was solved in his chest little by little, and the truth was coming to the surface more and more.

"First of all, do you think it's a sniper case?"

Mo Ming made a "1" gesture, intending to analyze the case bit by bit.

"Doesn't the bullets left at the scene, the bullet holes in the glass and the wounds on the deceased's head tell the whole story?"

Yan Wu didn't understand what Mo Ming meant, why wasn't it a sniper?

"No, I don't think that's the case, this should be the author's deceptive writing method, right?"

Yan Xi disagreed with Yan Wu's statement because he speculated on the author's psychology.

"Well, this is called trickery writing, and it is a common writing method in mystery novels, which is used to deceive readers. Its real purpose is to hide some truth."

"What's hidden there?"

Yan Xi was very devoted to thinking with Mo Ming, although he had not seen the reasoning works, but he maintained an unswerving curiosity, if there was anything he couldn't figure out, he would definitely continue to understand, this character was very similar to someone.

"Would you call the sound of glass being smashed by stones?"

"This ...... I haven't heard a gunfire except for the starting pistol at the Games, and even though I don't know it, I don't mistake it for a gunshot."

"You're right, this kind of thing is usually not misheard, after all, it is a confession, and it is impossible to guess at will, right?"

"Also, so the parking lot caretaker Zhang lied?"

"No, there wasn't that need, I guess I did hear the gunshots."

Yan Wu didn't understand the conversation between the two, what could he prove when he heard the gunshots?

"Huh? Doesn't that mean that the deceased was sniped?"

Yan Xi and Mo Ming shook their heads at the same time, Mo Ming was very satisfied with Yan Xi's reaction, and then asked him to say his opinion.

"The sound of gunfire is probably the sound of gunpowder exploding? Actually, I don't really understand, but one thing is for sure, the source of the sound must be on the gun's side, which means that if it's a sniper, the best place to snipe is on the roof of the building 500 meters away, so the person who hears the gunfire should be the person over there, not Xiao Zhang from the office building."

After Yan Xi finished speaking, he glanced at Mo Ming, wanting to confirm his conjecture, Mo Ming nodded, very satisfied, it should be said that this is what Mo Ming wanted to express.

"That's what it looks like."

The squad leader suddenly realized, and looked at the two of them with admiration, which is really amazing. But this admiration did not last long, because she had her own thoughts, and then found that it was not rigorous.

"You can't say the same about this, what if Xiao Zhang heard the sound of glass breaking, and then experienced this murder, so it's okay to think of it as a gunshot, right? Also, you can't take this side of the word for it, right?"

"That's right, that's my second point."

Mo Ming changed the gesture from 1 to 2, and the two listened carefully.

"Yan Xi, have you ever learned similar triangles? I think it's junior high school knowledge, right?"

Yan Xi nodded, he was actually quite serious about studying, and mathematics was still his better field.

"Well, do you have a pen and paper?"

"I'll go to the boss and ask for it."

Yan Wu actively got up to get the paper and pen, and after a while, a blank piece of paper and a ballpoint pen arrived in Mo Ming's hands. Mo Ming drew something very roughly on the paper, and after a while, he could see that it was a group of similar triangles.

The triangle is a right-angled triangle, with a base length of 500 and a height length of 230, and then a high line of 1 is made inside the triangle, which is vertically down.

"What is this?"

"The apex is the location of the deceased, and a point on the high line is the roof of the building, which is the position of the sniper, and one meter is the height of the window. Based on these conditions, it is impossible to snipe."

"Huh? Why is it impossible?"

Although Yan Wu understood the meaning of this triangle, Mo Ming said something like this, which made her completely incomprehensible.

"Sister, I'll explain to you. If you snipe on the rooftop, the hole in the glass shouldn't be one meter high, because then the sniping range will be the small triangle inside."

Yan Xi took the ballpoint pen and then painted the small triangle into a shadow, this position is within the range of the sniper's play, in short, it is impossible to achieve.

"In this triangular area, Chairman Chen can only squat on the edge of the wall and then remain motionless to let the murderer shoot him, even if he does make this action, the way he fell is not right."

Mo Ming said and handed the white paper with the title written on it to the two of them, circled the description of the deceased lying on the ground, and after the two read it, they instantly understood, and then nodded.

"If that were the case, the deceased would have been leaning against the wall, but the deceased was lying in the middle. It shows that before being shot, he was standing relatively far away from the window in his office, about two meters or closer to three meters."

Mo Ming took the pen in his hand, turned around, and the corners of his mouth rose slightly, now he understood, and in this time of thinking, he also figured out the motive by the way.

"What else? Xiao Li's method of killing?"

Yan Xi couldn't wait, her heart was very longing, eager for answers.

"Murder, it should also be shooting, didn't Xiao Zhang hear the gunshots? It should be Xiao Li who went to Chairman Chen's office with a gun to commit murder. The rest is easy to explain, the deceased's pupils dilated before he died, obviously frightened, that is to say, it was not a snipe, it was a burglary, and then the murder weapon. Only personnel from the Department of Security are allowed to bring them in. There is a security check on weekends, which can rule out Secretary Wu."

"Wait, what if Secretary Wu hid the gun before?"

"Well, this is unlikely, how can a gun be placed in the company with confidence, if it is discovered, not only will the purpose of killing be lost, but it may also be suspected, it will not be done, the risk is too great."

"Well...... Yes."

Yan Xi nodded.

"So, at around 14:30, Xiao Li went to the chairman's office and shot the chairman to death, probably with a pistol, and he should have brought a muffler, but because the floor on the fifth floor is not high, Xiao Zhang heard it. After Xiao Li finished killing someone, he chiseled a hole in the glass, and then left a bullet, which created the illusion of sniping, at this time, he only needed to flush the murder weapon into the sewer, and with the city's waterproof system, hide in a cold corner where no one was around."

After Mo Ming finished speaking, he looked at the two of them and waited for their questions, because he might not have spoken very clearly. But the two didn't ask any questions, Yan Wu looked at Mo Ming with some admiration, and Yan Xi was cheerful after a difficult problem was answered.

"Reasoning games are also quite interesting, Brother Mo Ming."

"Mo Ming, I didn't expect you to have such a hobby, I'm sorry to always think that you were just a simple dead house."

"Apologize in a humble tone!"

Mo Ming glanced at her.

"But I have to thank you, Yan Xi, my task is complete, I can hand over the errand, thank you."

Mo Ming got up and was about to leave, but now he just needs to pay and then slip away, and the two of them are still immersed in the reasoning game.

"Brother Mo Ming, have you forgotten something?"

Yan Xi stared at Mo Ming suspiciously, he was puzzled not by what he asked Mo Ming for, but by whether this guy was pretending to be stupid?

"Ah, this, I almost forgot, sorry, sorry."

If you fail to escape, let's sit down honestly.

"Mo Ming, just give me a hint, I think Xiaoxi still likes your cousin a lot."

"Well, cousin Mo Ming, help me."

「…… Don't be so affectionate."

"Just a reminder, please."

Yan Wu clasped his hands together, lowered his head, and asked Mo Ming very religiously, Mo Ming complained in his heart, this guy is too doting on his younger brother.

"Okay, I'll tell you a little."

"Thank you, Brother Mo Ming, I'm so touched."

"Don't be moved, it's just an equivalent exchange, you helped me solve my weekend homework, I'll tell you some information, it's just a win-win situation, it's not free."

Mo Ming didn't want to seem too enthusiastic, he knew that the price of enthusiasm was to be endlessly disturbed by others, and ah, if you don't want to one day, it's obviously not your obligation, but you will also be complained about, although Mo Ming doesn't want to speculate on people's hearts, but he still understands this very well.

"Since the equivalent exchange...... Then why did Brother Mo Ming leave just now?"

Yan Xi's casual words made Mo Ming feel ashamed, and his face flushed slightly.

"It's not leaving...... It's forgotten. Okay, don't talk about it, I'll give you some advice."

"Listen up."

Mo Ming coughed, looking like an old professor was about to start a class, but he was obviously not suitable for this style, and he was not very good at preaching this kind of thing.

"First of all, don't do anything more today."

"Today's event?"

"Yes, this kind of desire to indulge or something, it may be useful for other girls, but it is not useful for An Xiaofei, because she is not an ordinary girl. Got it?"

Yan Xi nodded, very teachable.

"Then, the hair was dyed back, An Xiaofei didn't like boys to pay too much attention to dressing up."

Yan Xi twisted the brown bangs on her forehead and bit her lip, a little unbearable, but still nodded.

"Finally, be single-minded, learn about your sister at this point."

"Huh? What are you talking about?"

Yan Wu's face was flushed, Yan Xi looked at her, a little puzzled, thinking to herself, is her sister very dedicated to a certain man? After reasoning for a moment, he smiled at Mo Ming.

"Understood, does Brother Mo Ming have any other opinions?"

"No, these three are enough for you to benefit for a lifetime."

Mo Ming spoke earnestly, and then looked into the distance, looking like an elder.

In the afternoon, when I returned home, I found An Xiaofei sitting cross-legged on the sofa watching TV with a sad face.

"What's wrong? Fei Fei."

An Xiaofei glanced at Mo Ming, fell on the sofa with a sad face, and after a while, her face turned red, and she tucked her face on the soft sofa, swinging her legs, looking very excited.

"What's wrong? Are you sick?"

Mo Ming was a little nervous, he had never seen this kind of reaction before.

"Ah! Yan Xi is so handsome! More handsome than before! I like it so much! I rejected him coldly today, will he hate me!"

Kindness...... Mo Ming doesn't understand people's hearts at all.
