Xiang Haisheng slowly picked up a glass of cold Coke and took a big sip, which made the extremely pungent spicy taste in his mouth disappear.

Looking out the window at the endless stream of people, he gradually fell into deep thought......

A day ago, in the evening......

Jiang Xiaoyu is dead.

Loud sirens resounded throughout the downtown area, red and blue lights flashed continuously, neatly dressed police officers came in and out, and countless technicians were trying to analyze everything at the scene.

Jiang Xiaoyu died, killed by the vicious copycat, and the latter, because of his stubborn resistance, he was killed on the spot by the police officers who arrived.

…… Or, she was killed on the spot by Xu Wenxin - that girl's marksmanship is always so accurate, which can be seen from her grades when she graduated from the police academy.

But...... Why does everything seem so unreal?

"Well, okay, that's it, goodbye." Yan Feng put down the phone, breathed a long sigh of relief, turned his head, and looked at Xiang Haisheng who was wrapped in a blanket.

"It's been a hard time, these days," he walked slowly to the police car, sat next to Xiang Haisheng, and patted him on the shoulder, "The case has been solved, Harvard University has decided to let you go back, and the ticket has been prepared for you......"

"I'm not leaving."

There was a certain firmness in his voice, Xiang Haisheng slowly raised his head and looked at Yan Feng: "The case has not been completely resolved, as a policeman, I can't go." ”

"Why didn't I see your energy in handling the case before?" Yan Feng chuckled, "Are you still suspicious of Wen Yifan?" ”

"Yes, my suspicions about him have never subsided—I'm almost certain that he's the 'Yunxiang Killer'." Xiang Haisheng frowned, "Especially now, if I don't find out the truth, I will definitely not go back." ”

"Then let me ask you, does this mood come from your competitive spirit towards Wen Yifan?" Yan Feng shook his head, lit a cigarette, and continued, "No, or rather, are you just jealous of him?" ”

"No, I don't have ......"

"Professor Xiang, to be honest, I can understand your current mood, but your current state is not the state of handling cases." Slightly exhaling a puff of smoke rings, Yan Feng slowly explained, "All your conclusions now are with subjective emotions, or in a sense, you have already determined in your subconscious that Wen Yifan is the Yunxiang murderer, and all the conclusions after that are based on this psychology, to be honest, if we rely on this feeling to handle cases, I don't know how many more unjust cases will be in the world." ”

- That's because you don't know, Wen Yifan has already admitted the fact that he is a "Yunxiang Murderer" in front of me. It's just that I don't have any evidence right now.

"You mean, I'm going to be scared by the situation today?" Xiang Haisheng shook his head, as if he wanted to avoid the question, he continued: "Whether it is being kidnapped here by Jiang Xiaoyu, or witnessing that rusty imitator killing Jiang Xiaoyu and disemboweling Jiang Xiaoyu in the factory, I am indeed very frightened, but I have not lost my mind as much as you think!" ”

"Then why are you shaking? I've been shaking since just now," Yan Feng pursed his lips, and Xiang Haisheng in front of him seemed to be about to have a seizure again, so he said with a smile: "Just kidding, I can see that you haven't lost your mind." ”

"Hmph," Xiang Haisheng snorted coldly, and then said, "The reason why I haven't lost my mind is because I can see that they have no killing intent towards me. ”

"During the time I woke up unconscious, I didn't know what was going on, but through the conversation with Jiang Xiaoyu after waking up in the factory, I found out that she didn't actually want to kill me, but kept intimidating me, saying that she wanted to kill me for revenge, but her attention kept on the watch, and it felt like she was waiting for someone," spread his hands, and Xiang Haisheng continued: "If you follow Officer Yan's speculation, Then Jiang Xiaoyu was probably waiting for the 'Yunxiang Murderer' who killed two policemen one after another and committed a bloody crime ten years ago. ”

"And after that, the arrival of that clumsy imitator seems to be particularly disobedient," frowned, and explained to Haisheng: "First of all, please rule out that he came there by chance, because Yunxiang is such a big place, where he goes is not good, why do you want to come to this extremely hidden factory?" Also, why did the action stop for so long, and why did it happen that I was kidnapped again? And why, after entering this factory, did he turn a blind eye to me, but instead had to dismember the victim in front of a stranger, in front of a stranger, in the extremely difficult place to move? ”

He spoke of his suspicions in a tone that still trembled a little, and kept asking questions.

"These are actually very easy to explain, let me analyze them for you one by one," Yan Feng chuckled, and then said: "First of all, there is about the arrival of that copycat, as you said, this is indeed not a coincidence, but it was instigated by someone, and this person ...... It's what we call the 'Yunxiang Killer'! ”

"Just a few hours ago, the police received reports from the four suspects one after another, and they submitted four different emails, all of which mentioned that if it is a real 'Yunxiang Murderer' copycat, then follow the instructions on the mail, and report the case at a specific time, and hand over the letter to the person at the police station, so that the 'Yunxiang Murderer' can determine which one is his real copycat by stealing the time of the police station."

"Conversely, wouldn't the police department also use this method to deduce which offender to arrest?"

"It's not that simple, you come to see this," Yan Feng said, taking out four printed emails, "This uses time encryption, and the Yunxiang killer is very cunning to encrypt the content of the time part of the four emails." Of the four emails that have been turned in so far, three of the letters have the exact same part about time, and only one letter has the same part about time, and the other three are exactly reversed. (For example, the first three letters are 17:27 and B is 17:56, so the fourth is the exact opposite) This leads to the fact that we don't know whether the fourth letter reverses the time according to the instructions on the email, so that it becomes a different letter; Or maybe one of the three letters was the same as the fourth, but it was changed to be different. And the time when everyone received the email was around 17:27 and 17:56, almost everyone immediately called the police after receiving the email, so if you want to judge who is a copycat through this method, there is no way to start, only the real Yunxiang murderer can know his identity. ”

"As for why Jiang Xiaoyu kidnapped you, the responsibility for this is actually on you." Spreading his hands helplessly, Yan Feng sighed, "She thinks you are the policeman who shot Jiang Qing." ”

“？” Xiang Haisheng looked puzzled and looked at Yan Feng in confusion.

"It's very simple, Jiang Xiaoyu has always held a grudge against the policeman who shot her brother to death, but she didn't know which one it was because of too little intelligence, but by chance she learned that the policeman was receiving psychological treatment from Wen Yifan, so she had been squatting outside his villa for those days," stepping on the cigarette butt, Yan Feng patted him on the shoulder, "And then you also know the follow-up, in the past two days, you have drilled into Wen Yifan's house in the afternoon, which has been suspected by her, in other words, She thought you were the policeman who had been coming to Wen Yifan to see a doctor, so she killed the killer. ”

"Then, from this point of view, in fact, Wen Yifan has been exonerated from the crime," Looking at the dark sky, Yan Feng frowned slightly, "First of all, we can see that under this series of actions, what is hidden is the control of the situation by the 'Yunxiang Killer', and his desire to conceal the identity of the imitator - otherwise he would not have gone to great lengths to encrypt those letters, and the kidnapping of you by Jiang Xiaoyu is also the result of his deliberate guidance- This can be seen from the documents Jiang Xiaoyu carried with her and the evidence left in her stolen car, all of which were provided to her by the Yunxiang Killer, so in this way, Wen Yifan's suspicion was ruled out, because it was the police he reported that allowed us to save you in time. After all, if he really wants you to die, then if I were him, I would definitely not choose to call the police, but directly let Jiang Xiaoyu rob you, and then wait in the newspaper for your death the next day. Therefore, my advice is ......"

…………………

He understood what Yan Feng meant, if Wen Yifan was really a "Yunxiang Murderer", then his purpose should be to conceal the identity of the imitator, and at the same time kill himself who was a threat to himself, and the "Yunxiang Murderer" could also obtain detailed information from the police. But for now, none of these two articles match either of these two articles - it was he who called the police, which led to the death of the copycat, and he had no way of getting information from the police.

But he knew that it was all a trick laid by the cunning wolf.

In fact, he didn't think about this at the time, but through the conversation with Professor Smith that night, he quickly figured everything out.

………………

"In my opinion, the police are targeting in the wrong direction. The real method used by the Yunxiang killer to confirm his identity should not be confirmed according to time, this is just a layer of tricks. Smith took a sip of his coffee and continued, "Actually, you found out, didn't you?" The two letters at 17:27 at time A were sent around 17:27, while the last two letters at 17:56 at time A were sent around this time, and according to the local police, almost all of them reported the crime at the first moment they received the email, which means that it is difficult to tell when everyone reported the crime.

"Therefore, time does not accurately determine the identity of the copycat, this is just a trick he put on the surface, in fact, it is pointless to simply dwell on this point - if you really want to do what you said, he did admit in front of you that he had the truth about the 'Yunxiang Murderer', it means that he did have enough confidence to kill you."

"In this way, the previous events can be almost perfectly connected," Smith said slowly, as the morning sun shone into his room from the United States through the monitor, "Let me make a bold assumption for you!" The Wen Yifan you are talking about, it is very likely that he first planned the murder of the Sichuan restaurant you said, and deliberately exposed his flaws for this. ”

"This seems to be difficult to understand, but please think about it carefully, why did Jiang Xiaoyu have murderous intent towards you?" Looking at Xiang Haisheng's puzzled expression, Smith smiled slightly and explained: "Because she mistakenly thought that you were the policeman who shot Jiang Qing, she kidnapped you, and the reason why she thinks so is because you have been visiting his villa to find the truth, isn't it?" ”

"But isn't that the teacher's suggestion?" Xiang Haisheng asked.

"Yes, that was my proposal, but now it seems that I was careless and put you in such a situation, and I should apologize to you," bowing his head slightly apologetically, Smith continued: "Now it seems that his flaw at that time was probably deliberately exposed to you, and this flaw can only be discovered by you, which confirms this from the side - he deliberately made you suspect him, the purpose is to make you visit his villa in order to find evidence, so as to achieve the purpose of killing people with a knife!" ”

"This was my negligence, because I didn't expect that this cunning murderer could grow up so fast," there was a slight emotion in his voice, and Smith sighed: "Originally, through the investigation of him, I thought that this was a slightly cunning head wolf - although for ordinary agents, and even for the FBI, this is a more tricky enemy, but once you meet the top people in criminal investigation, you will naturally show flaws." But if all this is as I imagined, I can tell you responsibly that this is definitely an extremely dangerous 'monster' that even I have to deal with carefully. Ten years of growth have given him the confidence and strength to face any challenge calmly, and for him, even if he is in a desperate situation, he can escape with absolute confidence, and for such an enemy, the normal legal process will not play any role - because I believe that even if he succeeds in bringing him to court, he will be able to use all means to exonerate himself. If he were in the United States, I wouldn't have gone through any judicial process, and I wouldn't have hesitated to shoot him the first time I saw him. ”

"So what should I do?"

"Let it go, Harry, you're no match for him, I've already started investigating, and I'm sure I'll be able to figure out how to deal with it soon......"

………………

- No, teacher, you're wrong, I'm not that bad.

Looking at the white clouds in the sky, a touch of unwillingness crossed his eyes, and immediately disappeared, he slowly got up, pursed his lips, as if he was swearing some poisonous oath.

In his opinion, this is naked contempt - Smith doesn't think he is better than that damn Wen Yifan, and what he has to do now is to prove himself!

That's why, he's here.

According to Smith's reasoning, this Sichuan restaurant is the key to everything, and it not only represents the first cooperation between Yunxiang Killer and Jiang Xiaoyu, but also the beginning of the trap laid by Yunxiang Murderer.

If you really want to find a flaw, here is the best solution today.

When he came to this position and sat down, he further affirmed the idea that Wen Yifan was the source of all this - the glass that was originally surrounded on three sides of the Sichuan restaurant, two of which could not be seen here because of the angle, and the glass that was facing it was completely blocked due to the slightly complete "corner" design and the pillar in the middle of the courtyard, although after that incident, this Sichuan restaurant was installed with surveillance, but it does not mean that there was any surveillance here before that that could be photographed here.

So he came here, and through the memories of the scene that day, he ordered the exact same food as Wen Yifan at that time, trying to find the latter's psychological state at that moment.

- As long as you find the psychological state at that time, you can follow the clues to find the loopholes, as long as you can find the loopholes, you can ......

With the action of getting up, a wave of anger called "unwilling" seems to slowly rise with the action, which is the determination to win, and it is also the determination to fight everything!

- This hatred that humiliates me in front of my face, I must be honored tenfold......

Knock –

Like the ringing of the bell from the depths of the church, or like the dull and vigorous explosion on the battlefield, Xiang Haisheng only felt that the blood that was originally boiling suddenly solidified at this moment, and all that was left was a white expanse.

Heart......

It was as if he had been hit the heart by a heavy hammer, and the heart that was beating violently with the boiling blood seemed to be completely out of control at this moment, and the violent beating made his eyes seem to be covered with a black cloth, and he could no longer see anything.

- Damn it...... Is it heart disease......

Panting heavily, he subconsciously reached for his wallet, only to find that it was empty!

- No...... It's gone?!

One hand clutched his chest, his pale cheeks dripping with sweat, and he tried to rummage through every pocket with his trembling left hand, but still found nothing!

- Where did you go...... Where have you been!

"Professor Xiang, what are you looking for?"

A soft voice came slowly, this voice was so gentle, but at this moment it was so hidden in his eyes!

"Yes...... It's you! ”

With the last bit of strength, Xiang Haisheng stood up like crazy, trying to identify the appearance of the people around him, "Give it to me, give it back to me!" ”

"Bastard, give it to me! Give it back to me! ”

"Farewell, Professor Xiang."

With the last sound in his ears, his eyes went black and he lost all consciousness......
