[Suppose the cover of the new book you see is a big beauty...... Believe me, that's a beautiful misunderstanding...... And it's being resolved...... Cover your face and run away......]

After saying his opinion, Fang Yuan turned his gaze to Dai Xu, hoping to judge whether he agreed with his opinion from his reaction, but Dai Xu didn't make any obvious reaction, but continued to ask: "Do you think, in the environment of City A, if you were asked to choose a place to throw the body, where would you choose?" ”

Fang Yuan didn't think about anything else, and hurriedly thought about this second question: "Normally, throwing a corpse must be to find a place that is as remote as possible and few people pass by, so as to avoid being discovered soon, if there is no car like me now, it will definitely not work if I want to carry a corpse to the wilderness too far away, renting a car is too easy to expose my whereabouts, after all, many rented cars have GPS records, and it is even more unrealistic to take a taxi or use other public transportation, You'll have to choose a location within the city limits. Or if I have a car, if it were me, I still wouldn't choose to drive to a place that is too remote and desolate in the suburbs, because going out of the city will inevitably need to take the road, passing through a toll booth or something like that, that kind of place either has a toll collector on duty, or there is a surveillance camera, in short, it is easy to leave traces, if the deceased is found, confirm the identity, find out the people who have had a relationship with the deceased before his death, and have contradictions, as long as he checks their license plates, it is easy to determine whether they have been haunted near the place where the body was dumped. This is also easy to expose, I think the murderer in this case, whether he is bold or cunning, dares to cut off the flesh of the deceased and throw it everywhere, which in itself shows that this person will definitely not be too timid, and he will not be very reckless, he must have some purpose in doing this, or he is planned, such a planned murderer, in such an important link as throwing corpses, will not be brute force without consideration. That's my opinion, not necessarily true. ”

"You're thinking a lot." Dai Xu turned his head and smiled at Fang Yuan while driving, "When I was at the scene before, I was in a daze thinking about these things?" So why not speak your mind? ”

Fang Yuan was a little surprised, she thought that Dai Xu was walking around by Lin Feige and Ma Kai at that time, and she didn't know what she was busy with, so she wouldn't notice herself at all, but she didn't expect him to notice, and she also guessed that she was thinking about the case in a silent voice, which made her a little embarrassed, nodded and said, "I'm just foolish, and I think what you said about Ma Kai before is quite reasonable, there are so many professionals present, I still need to listen and watch more, and learn more, It's better not to have an axe in the class. ”

"This is not right, in front of professionals, blurting out without thinking, and drawing conclusions at will, that is called the class axe, reasonable, well-thought-out, called clarifying the point of view." Dai Xu said very casually, and after finishing speaking, he suddenly changed the topic and asked, "Do you know the speed at which corpses decay in the soil?" ”

"I learned some during class, it's not very detailed, I remember I'm afraid it's not particularly accurate...... Fang Yuan struggled to recall what he had learned in class, "Probably if you are exposed to the air, for the time being, you don't consider those objective factors such as climate, temperature and precipitation, if you simply talk about the general situation, it may take about a year for the corpse exposed to the air to ossify, and it will be slower in the water and soil, if I remember correctly, it should be the speed of 8:2:1, right?" If it's winter, and it's dry and cold, it's going to be very, very slow, or even rotten. ”

"Then if the meat on the corpse is removed as much as possible, only a small amount of residual zài bone surface remains, and it is buried underground in this form, and when the spring comes, the temperature of the ground warms up, the ice and snow melt, and the soil moisture increases, the small amount of meat remaining on the surface of the corpse will begin to rot, if we do not receive a report that it is suspected that human flesh has been found, then after a long time, someone finally finds the bones buried in the ground, and by that time, the corpse may have been completely ossified. In this way, there will be very strict interference in judging the identity of the deceased and the time of his death. Dai Xu seemed to be chatting with Fang Yuan, and it seemed to be talking to himself.

Fang Yuan listened to his words, but felt as if his mind had suddenly opened up, and between Dai Xu's question and answer with himself, he was actually using such a casual way to explain his own opinion on why the victim's flesh was removed from his body. Although the two possibilities that Fang Yuan had considered before were also completely reasonable, but in comparison, Dai Xu's conclusion seemed more reasonable and more thorough and rigorous, the second possibility mentioned in his previous opinion was compared with Dai Xu's speculation, and it became almost untenable, if the murderer just wanted to reduce the weight or reduce the volume when throwing the corpse, dismembering the corpse could be achieved, so why bother to remove the meat from the bones?

"It turns out that the murderer's reason for doing this is to put a smoke bomb when the victim's body is found, confuse the police's investigation and interfere with the direction of the investigation!" Fang Yuan suddenly realized, looking at Dai Xu who was driving, he couldn't help but be a little impressed by him, if it weren't for Fang Cai he had drawn such a conclusion little by little, I'm afraid it would be hard for him to believe that such a lazy-looking man with thick lines actually had such a meticulous mind, "If it weren't for you to call me before, I might not have thought of this layer by now." ”

Unexpectedly, after listening to her praise, Dai Xu's expression looked a little confused, he turned his face to look at Fang Yuan, scratching his head: "Am I a little bit of a trick on you?" I'm just cranky and just talk about it. Also, you really don't call me senior, just call me by my name, the name of the predecessor is too raw. ”

Fang Yuan didn't expect him to react like this at all, the praise that had already reached his lips was stunned and couldn't be said in his throat, so he could only squeeze a smile at Dai Xu and nodded.

After a while, Fang Yuan gradually realized their destination from the scenery on the side of the road.

"Are we going to the children's park?" Fang Yuan was a little surprised, she thought that Dai Xu would first consider asking about the situation in a famous man-made scenic park on the outskirts of City A, but she didn't expect that his first stop would be to go straight to this City A, which is probably the oldest park - Children's Park.

"You know you're going to the children's park before you arrive?" Dai Xu turned his head to look at Fang Yuan, "I remember you said before that you weren't from City A?" ”

"Oh......" Fang Yuan froze for a moment, realizing that he had lost his words, and quickly laughed, explaining, "My family used to have relatives here, so I often came to play when I was a child, I came, remember." ”

"Then you have a pretty good memory, if you can remember the parks you visited when you were a child, if you ask the people you met a year or two ago, wouldn't you be able to remember them as well?" Dai Xu asked jokingly.

Fang Yuan didn't know how to answer, so he just smiled and didn't speak, just at this time, the car also drove to the gate of the park, only to see a long banner pulled there, which read, "The amusement area is expanded and repaired, the construction site is dangerous, please enter the park and consciously detour, and the consequences will be borne by yourself." Beneath the banner is the park's north gate, with two locked-up iron fences wide open, and the ground is dirty, with ice and snow, and the wheel marks of large trucks mixed with sand.

"Huh? It's being renovated and expanded, huh? Then let's ......" Fang Yuan finished reading the words on the banner, and then looked at the dirty condition at the door, thinking that in this way, Dai Xu would choose to change the target and go elsewhere.

Unexpectedly, Dai Xu didn't care at all, he drove the car straight into the park gate, and drove into the park, and didn't even see a staff member who came out to ask about it during the whole process, and in the process of Dai Xu driving all the way along the small road that is not too wide towards the depths of the park, they only encountered two cars in total, one is a small three-wheeler printed with the advertising sign of his own store that specializes in delivering grain and oil, and one is a medium-sized truck pulling wood, The entire park seems to be surrounded by blue colored steel plates, and only the playground area with the appearance of workers can be seen coming and going, and the rest of the park is very quiet, and there is no trace of anyone.

Fang Yuan looked through the car window, looking at the encircled play area inside the blue steel plate, it seems that it has been almost rebuilt, only some interior decoration work is still in progress, the construction site will of course be a little dirty, and the original playground has been expanded and transformed beyond recognition, not what Fang Yuan had in the past.

Nothing, it seems, will be set in stone. Fang Yuan sighed silently, thinking about the beautiful childhood memories he had left here, he couldn't help but feel a little concerned.

When Dai Xu passed by the gate of the construction area, he pulled the car on the side of the road and stopped, jumped out of the car and walked over to talk to the two workers who were resting and smoking at the door, and then returned to the car, and while continuing to drive forward, he said to Fang Yuan: "I heard that the park has been left alone recently because the construction time is not fixed, and the gate is open 24 hours a day, and you can enter and exit at will." ”

"Where are we going?" Fang Yuan watched the artificial lake in the park gradually being left behind with the car, and couldn't help but ask with some doubts, "If you drive further, it seems that there is only one road to continue, but that road seems to lead to the gate of another park." ”

Although she was not familiar with Dai Xu, and Dai Xu's way of doing things that did not follow common sense also made Fang Yuan scratch her head, but her intuition told her that Dai Xu deliberately drove over, and it was definitely not just to go around here.

"You know there's a big birch forest in this park, right?" Although Dai Xu was in an inquiring tone, it seemed that he was very sure that Fang Yuan knew there, "Let's go there and wander around!" ”
