Feiqing is none other than

"How is it, Xiao Qin?" Gu Jianyan looked expectantly at the boy sitting on the sofa.

"One is the latitude and longitude. The other is not only the latitude and longitude, but also the time." Qin Qing put the letter and the calculation paper on the tea table: "The time is two o'clock in the afternoon today. I wonder if it might be his next time." Crime warning?"

"Announcement for the next crime?" Gu Jianyan groaned and touched his chin: "Why did you send an announcement all of a sudden this time?"

Bai Yifei guessed: "Could it be some kind of stimulation? It looks a bit like a further provocation to the police."

stimulated...

All three were lost in thought.

Qin Qing hesitated and asked: "Uncle Gu, did you find any clues after taking back the latitude and longitude coordinates last time?"

"Yes." Gu Jianyan said: "I found two unnamed corpses buried underground and brought them back to the bureau. I haven't found out their identities yet."

"Is it possible that the suspect found the buried body and was found by the police, so he was stimulated?"

Gu Jian said nothing, as if thinking about this possibility.

After a long time, he picked up the calculation paper and stood up: "In short, I will send people to guard the time and place according to the forecast. If you have any new discoveries, please contact me in time."

The two amateur detectives both nodded at him.

After Gu Jianyan said goodbye and went out, the two looked at each other, they had thousands of words on their lips but didn't know where to start.

"Shall we... want to help?" Bai Yifei stammered a sentence to break the silence.

Qin Qing asked back, "Do you want to help?"

"Think about it . . . but I'm afraid it won't help."

"That's it." Qin Qing got up and walked towards the computer: "Let's check it ourselves first, and then contact Uncle Gu after we get a definite conclusion or evidence."

"Is this latitude and longitude on Google Maps reliable?"

"It should be okay. The virtual map has developed rapidly in recent years, and it can still be used as a reference."

"This latitude and longitude shows that it is near Lanshan Mountain... Could it be that the murder is going to be committed in the deep mountains and old forests?"

Qin Qing turned the swivel chair to Brother Gan, who was running wild in his head, and analyzed, "That possibility is not very high. According to our previous analysis, the suspect was stimulated because he found that the buried body was found by the police. From this we can It is learned that the suspect is not only arrogant, but also has a habit of returning to the crime scene from time to time to check his burial place."

Bai Yifei rubbed his goosebumps: "It's really abnormal."

Qin Qing nodded and continued: "I read it in a foreign criminal psychology book before, and this kind of prisoner who lingers on the crime scene is likely to like to watch the victim's victimization process. What is more important is the time of his crime forecast, so the chances of him being at the scene are very high."

"That's right." Bai Yifei nodded in agreement, "Then why can't the murder be committed in the mountains?"

"He told the time with such a big fanfare, he should have expected that there would be many police guards. In a deserted mountain, if a large number of police found his tracks, unless he knew the terrain well, the possibility of escape was very small. And even if he escaped successfully, It was never a good deal for him to lose the 'sacred place' where he could bury his body and go back and admire it."

Bai Yifei crouched down and sneaked over.

Qin Qing lifted her foot against him and said slightly annoyed, "What are you doing!"

Bai Yifei happily hugged the kicked leg: "I hug the thigh!"

Qin Qing: "..."

You are the pervert!

All in all, the two continued to analyze in a strange posture.

"My idea is that he probably found an area with many people, and then used some method to hide himself, kill people, cause panic, and then watch the scene before escaping."

"Is this really possible?" Bai Yifei scratched his head: "It's kind of fantasy... Could it be that there is Harriet's invisibility cloak?"

Qin Qing rolled his eyes at him: "Why don't you just say that he has a special function that can make him invisible?"

"Hey, in short, just find a place near Lanshan with a lot of people?" Bai Yifei searched the map in his mind: "Lanshan Amusement Park?"

"Amusement parks are basically family or friends group outings. I don't think it fits the prisoner's announcement of 'killing one person every month'. Hey, I should have asked Uncle Gu about the physical characteristics of the two unnamed corpses, so that we can filter The criminal chooses the victim's taste."

"Why don't we go wandering around Lanshan first, if we can meet the police, we may be able to find Uncle Gu, and then tell him what we think."

Qin Qing thought for a while, nodded and said, "OK."

Although Lanshan is called a mountain, it is actually a big mound.A few years ago, an amusement park was built at the foot of the mountain. Since it was not built for a long time and the equipment was still very new, there were quite a lot of tourists.

In addition, today is the weekend, and it is spring, which is a suitable season for traveling, many families choose to take their children to relax for a while.

"Do you want to buy a ticket to go in?" Bai Yifei looked around for the ticket office.

"Wait first." Qin Qing found a thumbnail of the amusement park and studied it carefully: "There are only two exits in the park, north and south. If a homicide occurs, you only need to seal the exit, and the prisoner will become a turtle in the urn. This seems a bit stupid."

"Then if there are many people and easy escape, wouldn't there be only two exits?"

"It's not quite right." Qin Qing pondered: "The time of the notice he wrote is two o'clock in the afternoon, which is not the time when the park opens or closes when there is a lot of traffic at the entrance and exit. Most people are playing in the amusement park. Hearty."

Bai Yifei was dizzy from hearing this: "Then he is still in the park? Is it possible for him to use a secret passage that few people know about to leave the amusement park?"

Of course, there is no way to know this. After all, it is not surprising that there are secret passages in such a large amusement park.

"Don't go in yet, time is not tight, let's walk around." Qin Qing dragged Bai Yifei around the outer wall of the amusement park.

The wall is made of cement, the wall is very high, and there are colorful cartoons on the wall.There is also an anti-theft net on the top to prevent overturning. It seems unlikely that it will be over the wall.

The amusement park is located at the foot of the mountain, and one side is very close to the slope.In the past, there was even a trapeze project, which was to slide down from a high place on a hillside with a hang glider, but it was later banned because the risk factor was too high.After the trapeze project was abandoned, the hillside was no longer associated with the amusement park.In order to prevent people from turning over the hillside to evade fares and enter the park, super high iron railings were also erected.

As he walked, Bai Yifei took the thumbnails he had just taken with the camera for comparison.Suddenly he said "Huh?", stopped and pointed to a certain place and said, "It seems that you can enter here?"

"Where?" Qin Qing turned to look.

"Here." Bai Yifei handed over the camera: "This building didn't seem to be an amusement park before, but after the trapeze people disappeared, iron railings were built to enclose half of the building, half inside and half outside."

"From the picture, it seems that this is indeed the case. I don't know what kind of building it is. If there are doors or windows on the first floor, it is very likely!"

Bai Yifei put away the camera and pulled it up and said, "Let's go! Go and have a look!"

The two ran downstairs and found that it was an ordinary five-story building.

It is estimated that the amusement park also considered that someone would use this building to enter and exit, so all the windows facing the outside were sealed with anti-theft windows. Only the anti-theft door at the bottom seems to be accessible, but it is locked now.

"Can this door be opened directly from the inside?" Bai Yifei broke the doorknob curiously.

"Theoretically, it should be possible, but it may also be locked by the management staff." Qin Qing said while looking at the surrounding environment.

If you don't come out from this door, there really seems to be no other way.The iron railings are very tight, unless the opponent is a peerless martial arts master.

The two were struggling with each other, when they suddenly heard a loud noise coming from above their heads: "Hey! What are you two doing! Do you want to evade fare!"

scare?The two people below looked up at the same time, and saw an uncle in uniform lying on the window, glaring at them.

How to explain this, this, this?Could it be said that he came to be a detective?Who would believe it!

Bai Yifei hurriedly shouted: "Oh, we seem to have gone to the wrong place!" After shouting, he pulled Qin Qing and ran away.

On the way back, I happened to meet Gu Jianyan's police car.Gu Jianyan put down the car window with a face full of disbelief: "Why did you two come here... Did you find anything new?"

Qin Qing didn't answer him, but asked instead: "Uncle Gu, how are you here?"

Gu Jianyan got out of the car and signaled his subordinates to drive away first, and chatted with them himself: "That's right, the body corresponding to the latitude and longitude of the third letter has been found, and there is something on the body that has not been burnt this time. It is the work permit of Zhang Lanshan Amusement Park, so Let's come and see."

"Burned?" Qin Qing grasped the message in Gu Jianyan's words: "Are all the corpses burnt?"

"Uh..." Gu Jianyan realized that he had slipped the tongue, so he had to make up for it as an afterthought: "It's not particularly burnt, but every one has traces of being burned, and everything that can prove its identity has been burned away. You can't do this. Disclose to reporters or others!"

Bai Yifei quickly raised his hand to assure: "Don't worry, Uncle Gu, we understand."

Gu Jianyan glanced at them suspiciously, and finally had to change the subject and said, "It's your turn, why are you here?"

"We're just speculating." Bai Yifei waved his hand: "Thinking that the murderer might find a place with a lot of people, and the place he predicted is near Lanshan Mountain, so I came here to check the situation."

"Nonsense!" Gu Jianyan raised his face ferociously: "Two little brats! Knowing that the murderer might appear, they still came to watch the fun, don't they think their lives are too long!"

Bai Yifei was stupefied by him, and looked at Qin Qing for help.

"Sure enough, there was an act of arson." Qin Qing said thoughtfully: "No wonder I often go back to the scene of the burial to repeat the process of persecution."

"What do you mean?" Now it was Gu Jianyan's turn to be stunned.

"A certain criminal psychology book I read before said that the advantage of arson is that you don't need to face the victim directly, but the disadvantage is that you can't fully experience the entire process of persecution, so arsonists will always return to the scene to experience or fantasize That process. But the pleasure given by arson is limited. After several times of pleasure, the prisoner will pursue a more exciting mode, such as directly inflicting on-the-spot experience, or even letting others watch his inflicting process... Generally speaking, Although there are some deviations, it is somewhat similar to the prisoner this time."

Gu Jianyan opened and closed his mouth a few times in shock, and muttered, "... Which book are you reading?"

"It's not a book to be precise. It's a paper called "The Threat to Kill". A psychologist made a scale based on the paper. After research, they found that the ideas in the paper were indeed reflected in the prisoners, but the degree of correlation was still Statistical criteria were not met."

"..." Gu Jianyan was silent for a long time, and then asked in a wrong way: "How old are you?"

"Me?" Qin Qing pointed at herself blankly: "Sixteen, what's wrong?"

Gu Jianyan rubbed his hands excitedly: "Are you interested in coming to work in our bureau after studying in the police academy?"
