Xiyuan went to the toilet of the police station, then found a window just enough to accommodate himself to go out, closed the toilet door from the inside, then quietly turned on the faucet, and put his mobile phone on the toilet lid, and played non-looping music. It's all about covering up your travels. Then he slowly climbed out of the window, went to the back mountain, and went straight to the scene of the crime of the man in police uniform that day. This was done so that the group of detectives would not keenly grasp that all of this was related to Xiyuan, and that everything was a coincidence.

When Xi Yuan just slipped to the toilet, he went to the duty room to take a look, and he knew all the monitoring locations, so he escaped from the police station easily.

At the scene of this crime, it seems that nothing has changed, because there is very little flow of people here, and there has been no rain at all in the past few days, which is also a good time for Xiyuan to solve the case.

But it's too hard to find conclusive evidence. Because it's so dirty and there's nothing left on site. Xi Yuan remembered that after the man in black was shot, he left a pool of blood, but Xi Yuan didn't go from the end of the street to the street, it was estimated that he was wiped off by the man in police uniform, not to mention the clothes on the corpse or his fingerprints on the wall.

There is no proof of death..... The case is again at an impasse.

Just as Xiyuan was thinking and meditating, when he had no clue, a figure that Xiyuan was very familiar with slowly walked over from the street, Xiyuan naturally didn't want to be recognized, and then found a dark corner and observed all this secretly.

Recognized it, it was Xiyuan's classmate, Mengyue.

The little white dress holding the flowers still can't stop the full figure, which makes people can't help but want to develop. The tall and slender white legs make people fascinated. The yellow princess wears a painter's hat on the haircut, which is cute and lively. Mei Yu bent the ground, a little shyly lowered her crystal melon seed face, looked around from time to time, looked at it for a while, lowered her head again, and walked to the side quickly, her face was red and dizzy, as if she was waiting for someone? Well? Boyfriend?

Xiyuan thought about it, since he met an acquaintance, he wanted to do this, he had no choice but to find another opportunity, he didn't want to be someone else.

And then there seems to be another person in the back? Xi Yuan took a look! It's Song Yi! This little fat man, could it be that Mengyue's boyfriend is Song Yi? It's strange that Song Yi has been chasing Mengyue is something that the whole class knows, but in the past, Mengyue seemed to ignore him, and it didn't look like he had already chased him.

At this time, Xiyuan was more vigilant, and his body curled up even more, for fear of being discovered, he only dared to peek through the cracks, and when the two of them left, he himself could retreat.

Song Yi said: "Little beauty, I am ashamed of you, isn't it a spring heart!" Ask me to come here, usually you still ignore me, but now you are so active, look at your careful dress today, I will not blame the past, you can still be my girlfriend, rest assured, no one will dare to bully you at school in the future, you still have a lot of money to spend. That lewd gaze kept looking up and down between Mengyue's chest and thighs, and her hands kept rubbing hot and hot, as if she was about to go up and down.

"Don't come here... It's not you I'm making an appointment, I'm going to shout for help when you come over! Mengyue's face was pale, full of horror, thinking about how Song Yi could be here, and while gesturing with both hands, she stepped back in small steps.

"Could it be that stinky boy from Xiyuan again!" Song Yi seemed to realize that he had been tricked, and it was not him who Meng Yue had dated, and roared angrily, "I have long seen your eyebrows, it is a dog and a male couple!" Here today, no one will pay attention to you if you shout and cut your throat! ”

As he spoke, he strode towards Mengyue, grabbed Mengyue's pair of bright hands, and rubbed Mengyue's looming white rabbit with his rough cheeks. Mengyue couldn't resist, the strength was too disparity, she thought that maybe she was stuck here today, and she couldn't help crying.

At this moment, Xi Yuan did not help, but suddenly had an extremely crazy idea! This made his mind quickly sort out, and when Song Yi and Mengyue were mixing together, while they were unprepared, Xi Yuan quietly walked to the place where the man in police uniform committed violence again, and finally found a pool of genes left over from the violence of the man in black that night on a black stain! That's right! It is it, the most conclusive evidence! Although the men in police uniforms cleaned up the scene that night, they were very dense and did not erase the very fishy genes left by the stall!

Xiyuan's brain was abnormally awake at this time, and since he had been out for a long time, he would inevitably be suspicious if he didn't go back at this time, but he had to use the grafting point of Song Yi and Mengyue's case.

Xiyuan used his clothes and bought sunglasses on the stall to wrap himself tightly, walked to the fruit vendor at the corner of the street, gave him 100 yuan and didn't need to look for it, so he bought a pound of fruit and two pounds of bananas, and asked him to help deliver them to the end of the street, and someone would come out to get them. When the fruit stall owner saw the money, he agreed to come down, and then Xiyuan ran to the telecom business office, took out his smart Hatch watch, (with a communication card function), and then bought a communication card, and reported to the police, saying that someone was plotting against a girl in a dress at the end of K City Street. Then I flushed the telecom card down the toilet at the telecom office.

Then, turning over the back mountain, Xiyuan dodged all the surveillance cameras of the Public Security Bureau and came to the "own" toilet, at this time someone knocked on his toilet door, but Xiyuan had not yet turned inside! It should be that Xiyuan has been out for too long, and the meeting has already ended, and Xiyuan's father came to find his son.

At this time, Xi Yuan immediately flushed the toilet with the bucket of overflowing water, pretended that he had just gotten on the tuba, wet the water on his pants and clothes, and opened the door.

"You, what kind of tuba are you on? So long! It's really a rush to death, and now our police have received a report and want to rush to the scene of the destination immediately! Let's go! "Father gave Xiyuan a violent shudder.

"I.... The sound of the mobile phone is too loud, and I didn't hear you outside the door, so I'm fine. Xiyuan responded with a grin like a stupid son of a landlord's family.

"People are comfortable on tuba, but you are like fighting a war!" Xiyuan's father dragged Xiyuan out of the toilet and got into the police car.

On the streets of K City

Several white and blue lights and shadows galloped on the street, and the flashing of red and yellow lights added a dazzling color to the red and green lights. Sirens blaring through the sky, breaking through the sky, but it seems that the people here have long been accustomed to it, and after stopping to watch, they hang high and do not care about themselves.

In a moment, I came to the scene where the police received a call from a mysterious person.

The abuser had already fled, but only the lovely Mengyue in a beige dress remained in Xiyuan's impression. At this time, she was disheveled, hiding in the corner and crying, but she didn't know that her beautiful eyes had already been red and swollen because of this.

Xiyuan leaned over to comfort her, took off his coat and put it on poor Mengyue, who was also heartbroken at this time, hugged Xiyuan, and hung on Xiyuan's shoulder to cry. This heart-warming gesture, there is no doubt that Mengyue, who had just been destroyed, had a lot of good feelings for Xiyuan.

Seeing this, the police couldn't bear to be disturbed, so they had to collect evidence at the scene.

For such cases, such as crime tools, condoms, direct evidence, residual genes, bloodstains, fingerprints, etc., are all necessary search points.

For these efforts, the police carefully observed the crime scene, and it seemed that nothing was found, because there was no obvious evidence.

Xiyuan's father personally searched, while teaching his subordinates how to collect, while seriously groping for himself, he has been engaged in police work for many years, and keenly captured a puddle of extremely fishy genes in the obscure corners of the way.

"Hands-on collection", under the order of Xiyuan's father, the police carefully scraped up the filth with glass sheets, and then packed it in a sterile collection bag, ready to take it back for testing.

After cleaning up the scene, Xiyuan learned that Song Yi did not succeed because of the fruit stall owner's stopping, which made Xiyuan let go of the sanction of conscience. They got into the police car together, returned to the public security bureau to make a record, and were ready to release the person, but it was very strange that the mysterious person's report phone number, the police could no longer get through, but since the case was carried out here, it was unnecessary to contact the informant, so it didn't matter.

Xiyuan's father and the police learned that Song Yi did not succeed, and Mengyue himself did not plan to pursue it, Mengyue was also kind enough to help Song Yi and his classmates talk, and he looked down and didn't look up, so he said that it was just a conflict.

But what surprised the police was the genetic sample that had just been collected. Who is this for? Could it be that there was a real misdeeds there not long ago?

After the test results, they are taken to the computer for genetic comparison of the criminals.

The results surprised everyone! A police officer is actually on the list of criminals on the computer, and the genes are extremely matched, and it is even said that this person's genes are the same!

Studied but cannot comprehend! Because the police officer's file will not exist with the criminal file, this matter, someone must have done it, looking at the surveillance video, it was found that no one in the surveillance video had touched the computer except for the person on duty.

This matter can also be put aside first, it is not the crux of the problem, because a few days ago, the scene of the crime of the man in black was linked to the genes of this beach, which had a great relationship, and all of this could not escape the eyes of Xiyuan's father. They went to the conference room again to meet and discuss the case.

At this moment, after Xiyuan sent Mengyue away, he returned to the police station and recalled what he had done before.

First of all, he bought a strip of coffee powder from the store and a little laxative, and asked the police on duty to drink it, he went to the toilet, and at the moment he turned around, he was stuck in the monitoring angle, Xiyuan quietly plugged it into the computer with a USB flash drive, and used his mobile phone to remotely control it, and put all the police officers' files on the criminal files. In this way, the plan was perfectly executed, and the show began to this day.

After that, as long as the old trick is repeated, and the police officer on duty drinks a second sip of coffee, the police officer will naturally not be suspicious of Xi Yuan, after all, he is the son of his boss. Soon after, when he had diarrhea again, he could remove the USB flash drive. (The location of the computer USB flash drive interface is just not detected by the surveillance camera.) ）

Soon after, many elite detectives concluded that the death of the man in black must be directly related to the officer, and prepared to arrest him.

In the long dark night, there was a little more unusual atmosphere.
